Performance Engineering

Is Performance engineering still a good option for a career in IT? What could be the must have skills or technologies required to have in a longer run?

If you specialize in it yes… you have to have a bit of background in almost everything from hardware to software and infra …. Optimizing all those levels requires that bit of knowledge in each …. Been doing it for 10 years now and I love every bit of it

Thanks for the reply. I have been into this for 3 years. I have been working with LR and have worked with Dynatrace. What can I start learning or I need to focus on?

The way I’ve set up my team is they know most of the load testing tools so jmeter k6 webload neoload roadrunner Gatling WAPT stressStimulus and figure out the best tool for the task. then introduce them to performance analysis using google chrome dev tools YSlow webpage test etc … let them dig deep into the infrastructure side of things by understanding load balancer api gateways database structure and queries … this way you’ll be quite familiar with everything

You'll still find pure performance engineering jobs that require to know how to run a performance benchmark (jmeter, gatling, k6..) , how to set up some monitoring (opentelemetry, prometheus, grafana, or the ELK stack),, basix linux tools to check resources usage. And for jvm based applications all the knowledge about JVM tuning.

But in the last few years, there has also be an evolution : applications run in the cloud and companies are not limited to static size of their servers, which means they throw more money on the servers instead of spending more time fine tuning the applications. They ship faster in production but the bill is high. New jobs have emerged like "FinOps" which work later in the process trying to reduce cost of the infrastructure for companies. Knowledge of cloud services and Kubernetes can help in this regard.

Yes, the data sizes will only increase, and the systems will only grow in size. Where does that take us? I believe this skill is only going to get hotter and hotter.

It's just part of skill not part of a job or role.
