Cloud Hosting SLA Checklist: Availability, Support, Backup and Recovery

A cloud hosting service-level agreement can appear reassuring when it promises high availability and technical support.

However, an SLA is only useful when the business understands exactly what the provider is promising, how performance is measured and what happens when the service falls below the agreed level.

A headline such as 99.9% uptime does not explain:

• Which components are covered
• How downtime is calculated
• Which events are excluded
• How quickly support responds
• Whether backup is included
• How long recovery takes
• What compensation is available

Before signing a cloud hosting contract, the organisation should review availability, support, backup, recovery, security and commercial responsibilities separately.

What Is a Cloud Hosting SLA?

A cloud hosting SLA is a formal agreement describing the expected service level between the provider and customer.

It may define:

• Availability
• Support hours
• Response times
• Recovery commitments
• Backup frequency
• Maintenance windows
• Security responsibilities
• Monitoring
• Service credits
• Exclusions
• Escalation procedures

The SLA may form part of a larger contract, order form or managed-service agreement.

It should be read together with:

• Acceptable-use policy
• Support policy
• Privacy terms
• Data-processing agreement
• Backup policy
• Security documentation
• Pricing schedule
• Exit terms

Important commitments may be distributed across several documents.

Separate the SLA From Marketing Claims

Marketing material may describe a service as:

• Highly available
• Enterprise grade
• Fully managed
• Secure
• Resilient
• Always monitored

These terms do not always create contractual commitments.

The buyer should identify which promises appear in the signed agreement.

Ask:

• Is the availability percentage contractual?
• Is backup included in the purchased plan?
• Are recovery times guaranteed or only estimated?
• Is support available around the clock?
• Are security updates included?
• What remedy applies after failure?

A sales presentation should not be treated as a substitute for the SLA.

Define the Exact Service Covered

The SLA should identify the protected service clearly.

A cloud hosting solution may contain several components:

• Virtual server
• Storage
• Database
• Load balancer
• Firewall
• DNS
• Backup
• Network connection
• Management portal
• Monitoring platform

The provider may guarantee availability for its core infrastructure but not for the customer’s application.

For example, the virtual machine may be running while the website remains unavailable because of a database error.

The SLA should distinguish infrastructure availability from application availability.

Understand the Availability Percentage

Availability is often expressed as a percentage measured over a month or year.

Common figures include:

• 99%
• 99.5%
• 99.9%
• 99.95%
• 99.99%

Small percentage differences can represent significant downtime.

Approximate maximum downtime over a 30-day month may be:

Availability	Approximate downtime
99%	7 hours 12 minutes
99.5%	3 hours 36 minutes
99.9%	43 minutes
99.95%	22 minutes
99.99%	4 minutes

These values are illustrative.

The contract’s measurement method determines whether an incident counts.

Check the Measurement Period

Availability may be calculated:

• Monthly
• Quarterly
• Annually
• Per billing period

A monthly measurement normally gives the customer quicker visibility into missed service levels.

An annual calculation can allow several lengthy incidents while still producing an acceptable overall percentage.

Confirm:

• When measurement begins
• Which time zone applies
• Whether partial months are included
• Whether each service is measured separately
• Whether availability is averaged across several systems

Averaging can hide poor performance of one important component.

Ask How Downtime Is Defined

The provider should explain exactly when downtime begins and ends.

Possible definitions include:

• Service fails provider monitoring
• Customer opens a support ticket
• Majority of requests fail
• Entire virtual machine becomes unavailable
• Provider confirms an infrastructure incident

These definitions can produce different results.

A service may be unusable for the customer before the provider officially records an outage.

The contract should also explain whether severe performance degradation counts as downtime.

Check Who Measures Availability

Availability may be measured by:

• Provider monitoring
• Customer monitoring
• Independent monitoring
• A combination

Provider-side monitoring may confirm that infrastructure is technically reachable while users experience application failure.

Customer-side monitoring may better reflect actual business access.

A strong agreement should define:

• Monitoring location
• Test frequency
• Failure threshold
• Evidence accepted
• Dispute process

The business should maintain its own monitoring even when the provider supplies reports.

Review Scheduled Maintenance Exclusions

Planned maintenance is commonly excluded from availability calculations.

Confirm:

• How much notice is provided
• How often maintenance can occur
• Maximum duration
• Which hours are used
• Whether emergency maintenance is included
• Whether the customer can request another time
• Whether the application remains available during maintenance

A broad exclusion allowing unlimited maintenance can weaken the practical value of the uptime commitment.

For international businesses, the provider’s night-time maintenance window may overlap with the customer’s working day.

Review Emergency Maintenance

Providers may need to apply urgent security or stability updates.

Emergency maintenance may occur with little notice.

The SLA should explain:

• What qualifies as emergency maintenance
• Whether it counts as downtime
• How customers are notified
• Whether service interruption is expected
• How often it has occurred historically

Emergency maintenance is sometimes necessary, but it should not become a general exception for poor planning.

Understand Force Majeure Exclusions

Contracts commonly exclude events outside the provider’s reasonable control.

These may include:

• Natural disasters
• War
• Government action
• Widespread internet failure
• Large-scale power disruption
• Labour disputes
• Third-party infrastructure failure

The wording should not be so broad that ordinary supplier or subcontractor failures are automatically excluded.

Ask whether the provider remains responsible for:

• Data-centre supplier failure
• Connectivity supplier failure
• Hardware failure
• Staffing failure
• Capacity shortage
• Misconfiguration

The provider’s use of subcontractors should not leave the customer without a meaningful service commitment.

Customer-Caused Incidents

The SLA will normally exclude outages caused by the customer.

Examples may include:

• Incorrect firewall configuration
• Deleted server
• Application error
• Unpatched software
• Excessive resource use
• Expired domain
• Invalid certificate
• Compromised account

In a managed service, responsibility may be shared.

The contract should state which configurations are controlled by the provider and which remain the customer’s responsibility.

Infrastructure SLA and Application SLA

An infrastructure SLA may confirm that the virtual server is powered on and reachable.

An application SLA may confirm that the website, database or business application is functioning correctly.

Application-level commitments usually require managed services and monitoring.

Ask whether the provider monitors:

• Server availability
• Operating system
• Web service
• Database
• Application login
• Transaction path
• External dependency

A business-critical application may require more than basic infrastructure monitoring.

Single-Server Hosting and Availability

One cloud virtual machine can still be a single point of failure.

The provider may offer an infrastructure SLA, but recovery could require restarting or rebuilding the server after a host failure.

Higher availability may require:

• Multiple virtual machines
• Load balancing
• Replicated storage
• Database redundancy
• Several availability zones
• Automated failover

The customer should confirm whether the quoted architecture can realistically meet the required service level.

A strong SLA cannot compensate for an unsuitable design.

Availability Zones and Regions

Cloud platforms may separate infrastructure into availability zones or regions.

A multi-zone design can reduce dependency on one data-centre location.

A multi-region design may protect against a wider regional incident.

However, these designs increase:

• Cost
• Complexity
• Data replication
• Network traffic
• Testing requirements

The SLA should identify whether the service is:

• Single server
• Single zone
• Multi-zone
• Multi-region

Do not assume geographic redundancy is included because the service is described as cloud hosting.

Support Coverage

Support availability should be stated clearly.

Possible models include:

• Business hours only
• Extended hours
• 24 hours a day on weekdays
• 24 hours a day, seven days a week
• Emergency-only out-of-hours support

Confirm:

• Days covered
• Local time zone
• Public holiday treatment
• Contact methods
• Emergency process
• Additional charges

A service hosting a public website continuously may require round-the-clock incident response even if the customer’s office operates only during business hours.

Response Time and Resolution Time

Response time and resolution time are different.

Response time means the provider acknowledges and begins handling the issue.

Resolution time means the service is restored or the problem is corrected.

An SLA promising a 15-minute response does not mean the outage will end within 15 minutes.

The agreement should clarify:

• Initial response target
• Investigation update frequency
• Workaround target
• Restoration target
• Final resolution target

Guaranteed resolution times are more difficult to offer, but the customer should understand the expected process.

Incident Priority Levels

Providers often assign incidents to priority levels.

A typical structure may include:

Priority 1: Critical

Complete service outage or severe business impact.

Priority 2: High

Major functionality is unavailable, but some service remains.

Priority 3: Medium

Limited problem with an available workaround.

Priority 4: Low

General request, question or minor issue.

The SLA should define these levels objectively.

Avoid definitions that allow a complete customer outage to be downgraded because the provider’s wider platform remains operational.

Who Sets the Priority?

The customer may select the initial priority when opening a ticket.

The provider may then change it after review.

The agreement should explain:

• When priority can be changed
• Who approves the change
• How disputes are handled
• Whether response targets restart after reclassification

A critical incident should not lose its response commitment because of an administrative disagreement.

Support Contact Methods

Confirm which channels are accepted for urgent incidents.

These may include:

• Support portal
• Email
• Telephone
• Messaging platform
• Monitoring alert
• Dedicated account manager

Email alone may be unsuitable for a severe outage.

The business should know:

• Which number to call
• Which account to use
• Required authentication
• Which information to provide
• Who can raise an emergency ticket

Store these details outside the hosted environment so they remain available during an outage.

Escalation Procedure

The SLA should contain a clear escalation path.

It may identify:

• First-line support
• Technical specialist
• Duty manager
• Service manager
• Executive escalation
• Security incident contact

The customer should know when escalation is permitted and how to request it.

For long incidents, the provider should provide regular updates without requiring the customer to request every one.

Communication During Incidents

The provider should define:

• Update frequency
• Communication channel
• Information included
• Estimated next update
• Service-status page
• Final incident report

Useful updates should explain:

• Current impact
• Investigation progress
• Temporary workaround
• Recovery actions
• Next checkpoint

Repeated statements that the issue is being investigated provide limited operational value.

Root-Cause Analysis

After a serious incident, the business may need a root-cause analysis.

The report may include:

• Incident timeline
• Technical cause
• Contributing factors
• Recovery actions
• Customer impact
• Preventive changes
• Follow-up owners

Confirm:

• Which incidents qualify
• Delivery timeframe
• Whether reports are included
• Whether the customer can request one
• How confidential information is handled

A root-cause report helps the customer understand whether similar incidents are likely to recur.

Managed and Unmanaged Hosting

An unmanaged hosting service may provide:

• Virtual machine
• Storage
• Network
• Basic infrastructure support

The customer may remain responsible for:

• Operating-system updates
• Application support
• Security configuration
• Monitoring
• Backup
• Recovery

A managed service may include some or all of these tasks.

The SLA should list the management scope explicitly.

The word “managed” should not be accepted without a detailed service description.

Operating-System Management

For managed servers, confirm whether the provider performs:

• Security updates
• Routine patching
• Reboots
• Package updates
• Firmware coordination
• Vulnerability remediation

The agreement should explain:

• Patch frequency
• Maintenance window
• Emergency-update process
• Customer approval requirements
• Responsibility for application compatibility

Applying updates can create downtime, while delaying them can create security risk.

The process should balance both.

Application Support

Many hosting providers manage infrastructure but not the customer’s application.

Confirm whether support includes:

• Web server
• Database
• Content-management system
• E-commerce platform
• Plugins
• Custom code
• Third-party integrations

If application support is excluded, identify who will respond when the infrastructure is healthy but the website is not functioning.

The boundary should be documented before an incident occurs.

Monitoring Scope

The SLA should define what the provider monitors.

Possible items include:

• Server availability
• Processor use
• Memory
• Storage capacity
• Disk errors
• Network
• Operating-system services
• Website response
• Database health
• Backup status
• Security alerts
• SSL-certificate expiry

Monitoring should have:

• Defined frequency
• Alert thresholds
• Named response team
• Escalation procedure
• Reporting

Monitoring without response is only observation.

Backup Frequency

The agreement should state how often backups are created.

Possible schedules include:

• Continuous
• Every 15 minutes
• Hourly
• Daily
• Weekly

The schedule should match the business’s recovery point objective.

A daily backup may be sufficient for a static site but inadequate for an active database or e-commerce platform.

Ask whether backups are:

• Application consistent
• Crash consistent
• File level
• Image based
• Database aware

The method affects recovery quality.

Backup Retention

Backup retention defines how long recovery points remain available.

The SLA should identify:

• Number of retained versions
• Daily retention
• Weekly retention
• Monthly retention
• Archive options
• Deletion policy

A provider may advertise daily backup while retaining only a few days of history.

This may not protect against corruption or deletion discovered late.

Backup Location

Confirm where backups are stored.

Possible options include:

• Same server
• Same storage platform
• Same data centre
• Different availability zone
• Different region
• Separate provider
• Customer-controlled repository

A backup stored on the same physical platform may be lost during a wider failure.

For important systems, maintain sufficient separation between production and backup.

Backup Account Separation

Backups should be protected from compromise of the production environment.

Controls may include:

• Separate account
• Separate credentials
• Multi-factor authentication
• Restricted deletion
• Immutable retention
• Provider-managed access
• Cross-region copy

If one administrator account can delete the production server and every backup, the design has a serious weakness.

Backup Encryption

The SLA or security documentation should explain whether backups are encrypted:

• During transfer
• At rest
• With provider-managed keys
• With customer-managed keys

Confirm who can access the keys and how recovery works if a key is lost.

Encryption protects confidentiality, but poor key management can make recovery impossible.

Backup Monitoring

The provider should monitor whether backup jobs succeed.

Ask:

• Are failed jobs detected automatically?
• Who investigates failures?
• How quickly is the customer informed?
• Is backup age monitored?
• Are storage limits monitored?
• Are missed recovery points recreated?

A configured backup job does not guarantee usable protection.

Backup Testing

A strong service should include periodic restore testing or make it available.

Testing may confirm:

• Backup readability
• Database consistency
• Server boot
• Application operation
• Access permissions
• Recovery duration

Ask:

• How often tests occur
• Which systems are included
• Whether results are documented
• Whether a full application test is performed
• Who fixes discovered problems

Backup success and recovery success are different measurements.

Recovery Point Objective

The recovery point objective, or RPO, defines how much recent data may be lost.

The SLA should either state an RPO or provide a backup design capable of meeting the customer’s agreed target.

For example:

• 24-hour RPO
• 4-hour RPO
• 1-hour RPO
• 15-minute RPO
• Near-zero RPO

The provider should explain whether the target is guaranteed, designed or best effort.

Frequent backup does not guarantee the RPO when jobs fail or replication falls behind.

Recovery Time Objective

The recovery time objective, or RTO, defines how quickly the service should return.

The SLA should explain whether recovery includes:

• Infrastructure provisioning
• Data restore
• Application startup
• Testing
• DNS changes
• User access
• Business validation

A provider may quote a one-hour virtual-machine restore while the complete application takes six hours to return.

The RTO should cover the service the business actually needs.

Recovery Responsibility

The agreement should identify who performs each recovery task.

Responsibilities may include:

• Declaring the incident
• Selecting the recovery point
• Provisioning infrastructure
• Restoring data
• Starting applications
• Testing
• Changing DNS
• Reconnecting users
• Approving return to service

If the provider only supplies backup files, the customer may need another technical team to complete recovery.

Recovery Priority

During a large provider incident, many customers may need assistance at the same time.

Ask whether recovery is:

• Automatic
• First come, first served
• Prioritised by service plan
• Subject to staff availability
• Supported by reserved capacity

A recovery estimate based on an isolated test may not apply during a regional disaster.

Disaster-Recovery Architecture

Backup and disaster recovery are not the same.

Backup preserves data.

Disaster recovery restores the complete service.

A recovery design may include:

• Standby server
• Replicated storage
• Secondary region
• Infrastructure templates
• Automated deployment
• Load balancer
• DNS failover
• Documented runbook

The SLA should state which recovery components are included and which require additional services.

Regional Failure

If the provider’s complete region becomes unavailable, can the service run elsewhere?

Confirm:

• Secondary region
• Replication frequency
• Data consistency
• Activation process
• Recovery time
• DNS procedure
• Capacity reservation
• Additional cost

A single-region backup may not help when both production and backup depend on the same affected location.

Recovery Testing Frequency

Recovery plans should be tested regularly.

Possible schedules include:

• Quarterly
• Twice per year
• Annually
• After major changes

The test should reflect the real service and include dependencies such as:

• Database
• Identity
• Certificates
• DNS
• Network
• Third-party APIs
• Application configuration

The SLA should state whether testing is included or charged separately.

Security Incident Response

The service agreement should explain how security incidents are handled.

Review commitments for:

• Detection
• Customer notification
• Containment
• Investigation
• Evidence preservation
• Recovery
• Reporting

Confirm what qualifies as a security incident and how quickly the provider must notify the customer.

The provider should also identify the emergency contact route for suspected compromise.

Vulnerability Management

For managed hosting, ask who is responsible for:

• Operating-system vulnerabilities
• Web-server vulnerabilities
• Database vulnerabilities
• Application vulnerabilities
• Third-party plugins
• Network devices
• Management interfaces

The SLA may define update targets according to severity.

A critical vulnerability may require faster action than an ordinary routine update.

DDoS Protection

Cloud hosting may include some level of distributed denial-of-service mitigation.

Confirm:

• Network-layer protection
• Application-layer protection
• Automatic mitigation
• Traffic-volume limits
• Rate limiting
• Web application firewall
• Attack reporting
• Additional charges

Basic infrastructure protection may not cover application-specific attacks.

The service description should define the actual scope.

Data Location

The agreement should identify where production data and backups may be stored.

Review:

• Primary region
• Backup region
• Support-access location
• Subprocessors
• Cross-border transfers
• Disaster-recovery location

The customer should confirm that the arrangement meets contractual, privacy and regulatory requirements.

Subcontractors

Cloud providers may depend on:

• Data-centre operators
• Public cloud platforms
• Network carriers
• Backup providers
• Security vendors
• Support partners

The contract should explain:

• Which subcontractors are used
• Whether they may change
• How customers are notified
• Who remains responsible
• Where data is processed

The customer should not need to pursue several subcontractors after a service failure.

The contracted provider should remain accountable for the complete service it sells.

Data Ownership

The agreement should state clearly that the customer retains ownership or appropriate control of its data.

It should also explain:

• Provider access rights
• Support access
• Legal disclosure
• Data export
• Retention after termination
• Secure deletion

Avoid terms that give the provider broad rights to use business data beyond delivering the service.

Data Export and Portability

The customer should be able to retrieve its data in a usable format.

Confirm:

• Export formats
• Export tools
• Data-transfer time
• Egress charges
• Assistance
• Database export
• Backup export
• Configuration export

Portability is particularly important for managed platforms where the provider controls substantial configuration.

Termination Assistance

The agreement should define what happens when the service ends.

Review:

• Notice period
• Data-export window
• Migration support
• Final backup
• Additional charges
• Account closure
• Data deletion
• Certificate of deletion
• Continued access during dispute

The provider should not delete data immediately at contract termination unless the customer has been given a reasonable export opportunity.

Service Credits

Many SLAs provide service credits when availability falls below the target.

A credit may be calculated as a percentage of the monthly fee.

For example, the customer may receive:

• Small credit for a minor breach
• Larger credit for a serious breach
• Maximum credit capped at one month’s fee

Service credits usually do not compensate for actual business loss.

They are primarily a contractual remedy and incentive.

Check Whether Credits Are Automatic

Some providers apply credits automatically.

Others require the customer to submit a claim within a short period.

Confirm:

• Claim deadline
• Required evidence
• Submission method
• Approval process
• Credit timing
• Maximum amount

A credit process requiring detailed manual claims can reduce the practical value of the SLA.

Check the Credit Calculation

Credits may be based on:

• Affected service fee
• Complete monthly bill
• Downtime duration
• Availability tier
• Number of incidents

A customer paying for several services may receive a credit only against the small component that failed.

Review the actual likely compensation before treating the SLA as financial protection.

Repeated SLA Failure

The contract should address repeated service-level breaches.

Possible remedies include:

• Service-improvement plan
• Escalation
• Additional reporting
• Right to terminate
• Waiver of exit fees
• Migration assistance

A small monthly credit is not an adequate long-term solution when the provider repeatedly misses critical service targets.

Liability Limits

Cloud contracts often limit the provider’s total liability.

The limit may be linked to:

• One month’s fees
• Several months’ fees
• Annual fees
• Insurance coverage
• Fixed amount

The business should assess whether the limitation is reasonable compared with the potential impact of data loss or prolonged downtime.

Legal advisers should review important agreements.

SLA Does Not Replace Business Insurance

Service credits and contractual liability limits may not cover:

• Lost revenue
• Customer compensation
• Regulatory cost
• Recovery labour
• Reputational damage

The organisation may need appropriate business-interruption, cyber or technology insurance.

Insurance requirements should reflect the business impact of service failure.

Change Management

The provider should control changes to production infrastructure.

The SLA or service description may define:

• Change requests
• Approval process
• Maintenance windows
• Emergency changes
• Rollback
• Testing
• Customer notification

Poorly managed changes are a common cause of outages.

For managed hosting, the business should know which changes the provider can make without prior approval.

Capacity Management

Cloud resources can reach capacity limits.

The provider should monitor:

• Storage utilisation
• Memory
• Processor use
• Database limits
• Traffic
• Backup capacity
• Account quotas

The agreement should explain:

• Alert thresholds
• Upgrade process
• Customer approval
• Automatic scaling
• Cost impact

A service may remain technically available while performing poorly because it has insufficient capacity.

Performance Commitments

Availability alone may not guarantee acceptable performance.

Some agreements may include targets for:

• Response time
• Storage latency
• Network throughput
• Database performance
• Resource availability

Performance commitments are more common in managed or specialist services.

Where application response is commercially important, define measurable performance indicators rather than relying only on uptime.

Reporting

Regular service reports may include:

• Availability
• Incidents
• Support response
• Backup success
• Restore tests
• Capacity
• Security events
• Changes
• SLA credits

Confirm:

• Report frequency
• Format
• Level of detail
• Review meeting
• Data retention

Reports should support improvement, not only show a green status indicator.

Account Management

A managed hosting agreement may include a service manager or account manager.

Clarify whether the role provides:

• Regular reviews
• Capacity planning
• Incident follow-up
• Cost review
• Change coordination
• Improvement recommendations

An account manager should not replace technical escalation, but can improve communication and planning.

Price Changes

Long-term hosting contracts should explain how prices may change.

Review:

• Fixed term
• Annual increase
• Indexation
• Usage-based charges
• Currency changes
• Third-party price changes
• Renewal pricing
• Notice period

A low introductory price may not represent the long-term cost.

The business should also understand which services are billed separately during an incident or recovery.

Additional Charges During Incidents

Ask whether additional fees apply for:

• Emergency support
• Out-of-hours work
• Data restore
• Full disaster recovery
• Additional storage
• Data egress
• Security investigation
• Root-cause report
• On-site assistance

An incident should not become more difficult because commercial approval is unclear.

Where possible, define included emergency work and approval thresholds in advance.

Provider Financial and Operational Stability

An SLA is only useful when the provider can continue delivering the service.

Assess:

• Company history
• Financial stability
• Technical team
• Support coverage
• Data-centre relationships
• Insurance
• Business-continuity arrangements
• Customer references

A highly ambitious SLA from an under-resourced provider may be less valuable than a realistic commitment from an experienced one.

Customer Responsibilities

The agreement should list customer duties.

These may include:

• Maintaining contact information
• Protecting credentials
• Approving updates
• Managing application code
• Monitoring usage
• Paying invoices
• Following acceptable-use rules
• Reporting incidents promptly

Failure to meet these duties may affect SLA claims.

Responsibilities should be practical and clearly assigned internally.

Build a Responsibility Matrix

A responsibility matrix can show who manages each task.

Task	Customer	Provider
Physical infrastructure		Responsible
Cloud platform		Responsible
Operating-system updates	Depends on plan	Depends on plan
Application updates	Usually responsible	Optional
Backup monitoring	Depends on plan	Depends on plan
User accounts	Usually responsible	Support may assist
Recovery	Shared	Shared
Security incident response	Shared	Shared

The actual matrix should reflect the purchased service.

Unassigned tasks create risk.

Common SLA Mistakes

Focusing Only on Uptime Percentage

Availability does not explain support, backup or recovery.

Assuming a Response Target Is a Fix Target

A fast acknowledgement can still be followed by a long outage.

Ignoring Exclusions

Maintenance and customer-cause exclusions may remove many incidents from the calculation.

Assuming Backup Is Included

Some hosting plans provide no managed backup.

Accepting an RTO Without Reviewing Architecture

A single server may not support rapid recovery.

Relying Only on Service Credits

Credits rarely compensate for real business loss.

Failing to Review Customer Responsibilities

The customer may remain responsible for applications, updates and recovery decisions.

Ignoring Exit Terms

Data export and migration may be expensive or slow.

A Practical Cloud Hosting SLA Checklist

Before signing, confirm:

1. Which exact services are covered?
2. Is availability measured monthly or annually?
3. How is downtime defined?
4. Who measures downtime?
5. Does performance degradation count?
6. Which maintenance events are excluded?
7. Which third-party failures are excluded?
8. Is the architecture single-zone or multi-zone?
9. Is support available 24 hours a day?
10. What are the response targets by priority?
11. Are resolution or restoration targets included?
12. How often will incident updates be provided?
13. Is root-cause analysis included?
14. What does managed hosting actually cover?
15. Which systems and applications are monitored?
16. How frequently are backups created?
17. How long are backups retained?
18. Where are backups stored?
19. Are backups immutable or separately protected?
20. What RPO is supported?
21. What RTO is supported?
22. Who performs complete recovery?
23. How often is recovery tested?
24. Is regional disaster recovery included?
25. How are security incidents reported?
26. Where are production data and backups located?
27. Which subcontractors are involved?
28. How can data be exported?
29. What support is provided at termination?
30. How are service credits calculated?
31. Must the customer claim credits manually?
32. What happens after repeated SLA failures?
33. What liability limits apply?
34. Which incident services create extra charges?
35. Are responsibilities documented clearly?

A provider should be able to answer these questions in writing.

Final Recommendation

Treat a cloud hosting SLA as an operational document rather than a marketing promise.

Review availability, support, backup and recovery as separate commitments. Confirm what is measured, which incidents are excluded and whether the hosted architecture can realistically meet the stated service level.

Define response targets by incident priority, but also ask how restoration, communication and escalation will work during a serious outage.

Confirm backup frequency, retention, location, monitoring and testing. Agree practical RPO and RTO targets and identify who performs each recovery task.

Review service credits, repeated-failure remedies, liability limits and termination assistance. Do not rely on a high uptime percentage or a small credit to protect the business from the full impact of downtime or data loss.

The best SLA is one that matches the importance of the workload, assigns every responsibility and has been supported by tested recovery procedures.
