With cloud-based resources, teams can spin up infrastructure in seconds, begin testing immediately, scale up or down as needed, and easily eliminate resources that are no longer needed. In case of a spike in traffic, you can automatically spin up more resources, often in a matter of seconds. Improved performance and availability.

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.

As defined by the Google SRE initiative, the four golden signals of monitoring include the following metrics: Latency. Latency is the amount of time, or delay, a service takes to respond to a request. Traffic refers to the amount of user demand, or load, is on the system. Monitoring can provide a way to differentiate between.

A quick canary test was free of errors and showed lower latency, which is expected given that our standard canary setup routes an equal amount of traffic to both the baseline running on 4xl and the canary on 12xl. What’s worse, average latency degraded by more than 50%, with both CPU and latency patterns becoming more “choppy.”
