To ensure high standards, it’s essential that your organization establish automated validations in an early phase of the software development process—ideally when code is written. While the first guardian validates the traffic, the second guardian checks the business transactions generated during the observation period.

This includes metrics such as query execution time, the number of queries executed per second, and the utilization of query cache and adaptive hash index. That said, it should also be monitored for usage, which will exhibit the traffic pressuring them. This is not an exhaustive list but an example of what we can watch for.

If we had an ID for each streaming session then distributed tracing could easily reconstruct session failure by providing service topology, retry and error tags, and latency measurements for all service calls. Using simple lookup indices in Cassandra gives us the ability to maintain acceptable read latencies while doing heavy writes.

SLIs are the actual performance metrics of your services. For example, if your SLO states that your uptime must be 99.9%, the actual SLI must meet or exceed that performance metric in order meet that specific SLO. An agreement within the SLA that states specific metric, like uptime, response time, security, issue resolution, etc.

There is no way to model how much more traffic you can send to that system before it exceeds it’s SLA. Every opportunity for delay due to more work than the best case or more time waiting than the best case increases the latency and they all add up and create a long tail. Mu is the mean of each component, the latency.
