Are you new to SRE or taking on an SRE Manager role and looking to implement SLAs, SLOs and SLIs?

Here are some SLAs, SLOs and SLIs that you can consider to measure and ensure the reliability and performance of your services:

As an SRE (Site Reliability Engineering) manager/engineer, you can consider the following SLOs (Service Level Objectives), SLIs (Service Level Indicators), and SLAs (Service Level Agreements) to measure and ensure the reliability and performance of your services:

SLOs (Service Level Objectives):

1. Availability: The percentage of time your service is expected to be available to users.
2. Latency: The maximum acceptable response time for user requests.
3. Error Rate: The acceptable percentage of errors or failures in service operations.
4. Throughput: The number of successful requests your service can handle per unit of time.
5. Scalability: The ability of your service to handle increasing user load without performance degradation.
6. Recovery Time Objective (RTO): The maximum acceptable downtime for your service during a failure.
7. Durability: The probability of data loss or corruption, usually measured in terms of percentage.

SLIs (Service Level Indicators):

1. Response Time: The time it takes for your service to respond to a user request.
2. Error Rate: The percentage of failed or erroneous requests.
3. Availability: The percentage of time your service is up and running.
4. Uptime: The total time your service has been available without any interruptions or failures.
5. Throughput: The number of successful requests served per unit of time.
6. Request Success Rate: The percentage of successful requests out of the total requests made.

SLAs (Service Level Agreements):

1. Availability SLA: A commitment to the minimum uptime percentage for your service, typically agreed upon with customers or stakeholders.
2. Response Time SLA: A commitment to the maximum acceptable response time for your service.
3. Escalation and Resolution Time SLA: The maximum time allowed for escalating and resolving incidents or issues.
4. Communication SLA: A commitment to the frequency and quality of communication with customers or stakeholders during incidents or planned maintenance.

It’s important to define these metrics and agreements based on the specific needs of your services and the expectations of your users or customers.
