I'm experiencing a situation where my EC2 instances are constantly maxing out at 100% CPU usage. I need to figure out the best steps to diagnose and resolve this issue. Specifically, I want to know: 1) How do I identify if my applications are stateful or stateless? 2) How does the type of compute work with different tasks such as handling requests, processing jobs, or performing heavy computations? Based on these findings, I'm looking for potential solutions for each scenario, like vertical scaling for stateful apps or using auto-scaling groups for stateless apps. Any insights or advice would be appreciated!

Have you thought about using Application Performance Monitoring (APM)? It can give you a better insight into your application performance rather than just relying on infrastructure metrics. This might help you pinpoint the real issues behind the high CPU usage.
It's not always problematic when your EC2 hits 100%, it just means your CPU is being fully utilized. However, if it’s consistently at that level, you might start facing performance issues or crashes. It’s crucial to analyze if you actually need spare CPU capacity for peaks or spikes in traffic.
Honestly, it all depends on your architecture. If your applications are stateless, you might want to consider using microservices or even transitioning to serverless options rather than sticking with standard EC2 instances. It can save you a lot of hassle in scaling.
I can relate! I was consulting on a similar project where they were stuck with a legacy EC2 setup. We found a lot of wasted resources. Revamping the architecture helped tremendously!
That's true! If it's stable at 100% and your apps are still functioning without issues, you might not need to change anything. But consistently running at that level could cause instability down the road, leading to restarts or outages.
