What's in a DBaaS SLA
A DBaaS SLA (Service Level Agreement) is a key document that outlines what the service provider promises to deliver. It covers performance, security, and customer support. Understanding the main parts of a DBaaS SLA helps you choose the right service for your needs.
Main Parts of an SLA
Here are the key elements typically found in a DBaaS SLA:
Element
Description
Service scope
What the provider offers (e.g., database management, maintenance, support)
Performance metrics
Measures of uptime, response time, and data processing speed
Roles and responsibilities
What the provider does and what you need to do
Problem-solving steps
How issues are handled, including any compensation for service failures
Common SLA Terms and Measurements
DBaaS SLAs use specific terms to measure how well the service performs. Here are some you should know:
Term
Meaning
Uptime
How often the database is working and ready to use
Availability
How much of the time the database can handle requests
Latency
How quickly the database responds to requests
Throughput
How much data the database can process in a set time
Data durability
How well the database keeps data safe and intact
Knowing these terms helps you judge if a DBaaS provider meets your business needs. Next, we'll look at what providers promise for uptime and availability in their SLAs.
Uptime and Availability Promises
Uptime and availability promises are key parts of DBaaS SLAs. They show how reliable your database will be and how it might affect your work.
Industry Standards
Most DBaaS providers offer uptime between 99.9% and 99.999%. These numbers mean different amounts of downtime each year:

Daily
Every day
1 week
Weekly
Once a week
1 month
Monthly
Once a month
1 year
Different providers might have different backup plans.
RPO and RTO Explained
RPO (Recovery Point Objective): The most data you might lose if something goes wrong. It's measured in time, like 15 minutes.
RTO (Recovery Time Objective): How long it takes to get your data back and start working again after a problem. This is also measured in time, like 2 hours.
Knowing your RPO and RTO helps you plan for problems and get back to work quickly if something happens to your data.
Support and Upkeep Promises
Support and upkeep promises in DBaaS SLAs show how providers will keep your database running and fix problems.
Response Times for Issues
When things go wrong, you need help fast. DBaaS providers set different response times based on how bad the problem is:
Issue Type
Response Time
Critical (database down)
Under 1 hour
Non-critical
2-4 hours
Knowing these times helps you plan for possible problems.
Planned Downtime and Alerts
DBaaS providers often need to stop the service for updates. They usually:
- Plan these stops ahead of time
- Tell you when they'll happen
For example, ScyllaDB Cloud does updates every Monday and Wednesday from 05:00 to 08:00 GMT, adjusted to your time zone. Knowing this helps you work around these stops.
Steps for Unresolved Problems
If a problem doesn't get fixed quickly, providers usually:
- Send it to more skilled support teams
- Look for the cause to stop it from happening again
