What should you do while choosing the right SLOs? "A natural structure for SLOs is thus SLI ≤ target, or lower bound ≤ SLI ≤ upper bound." Lower bound SLOs ≤ SLI ≤ Upper bound SLOs This forms as a controlling characteristic while measuring and monitoring the entire system architecture. There is an intricate dependency between SLIs and SLOs. The target value of a service level is always measured only by an SLI. Here are few key practices that can help you in deciding the right SLOs. Thus, SLIs are the foundational blocks that help in building SLOs which in turn helps with overall reliability mentioned in your SLA.Ĭhoosing the appropriate SLOs or target values is in itself a complex technique! Here you have to list out the reliability values and help them understand your product's capabilities. This is a completely data-driven phase where you have to accumulate the data from customer queries, stakeholders' expectations, find the insights and finalize the target/threshold values to achieve better reliability.Īs the final step, you should create your SLA.
Secondly, you have to set targets of availability for achieving these indicators, which forms your SLOs. Remember these are a direct measure of your system’s behaviour in every stage of your business. These service-level metrics would help you gain customer trust and improve your system reliability and performance.Īs a service provider/vendor, you should start by coming up with key performance indicators that measure your product's performance, which forms your SLIs.
If you are a business that sells any product or service to your customers and assures them about your product capabilities, then you should draft your SLI, SLO and SLA now! How these SRE metrics help in drafting system performance and reliability
