Microservices can be a great way to work: the services are simple, you can use the right technology for the job, and deployments become smaller and less risky. Unfortunately, other things become more complex. You probably took some time to design a deployment pipeline and set up self-service provisioning, for example. But did the rest of your thinking about what “done” means catch up? Are you still setting up alerts, run books, and monitoring for each...

Collecting and Interpreting Large-Scale Data Collected @SkyUK

With the recent surge in highly available microsevervices with high incoming traffic, it is becoming more and more important to know how your service is performing right now and to be able to diagnose issues in production quickly. It took a while for us to understand how to produce meaningful graphs and alerts that help us truly understand our application performance.

We initially found that most developers did not understand...

Serverless architectures are attracting more and more interest from the IT professionals and companies hoping to lower the costs of creating and operating distributed systems without constant worrying about availability, scalability and capacity management. Despite all the attractive properties that serverless architectures offer, such systems still need to be comprehensively monitored to be effectively operated and maintain the expected quality of service and...

by Dr. Stefanos Zachariadis
Senior Software Engineer

Modern software development allows us to prove that new work is functionally complete. We write a set of executable specifications. We automatically execute them in the form of acceptance tests as part of our continuous delivery pipeline. When all the tests pass, we are done!

This approach is superior to what came before it but is by no means perfect. Testing frequently ends at the point of release, meaning that bugs in...

What is a way to have complete transparency of the state of a service? Ideally we would record everything - the inputs, outputs and timings - in order to capture highly reproducible and transparent state changes. However, is it possible to record every event or message in and out of a service without hurting performance? Join Peter for an exploration of the use cases and practicalities for having downstream services consuming all of the state changes of an upstream service in order to...
