I'm a software engineer at a startup with a focus on our largest product, which has grown significantly since its launch 11 months ago. Initially, we deployed on a simple platform but switched to EC2 instances as our user base exploded to 30,000 daily active users. I took the lead on our CI/CD setup, managing successful deployments with minimal downtime. Now, I'm looking to advance my DevOps skills and explore setting up observability with Prometheus and Grafana. Specifically, I have two questions: 1) What additional skills should I focus on to improve my DevOps expertise while continuing my role as a software engineer? 2) For deploying Prometheus and Grafana, I'm considering using a separate EC2 instance. Would a 2 core machine with 2GB RAM and 30GB disk enough for running both services? What are the minimum requirements for these tools to run effectively?

In my view, DevOps encompasses much more than just software reliability. It’s about creating product teams that are responsible from planning to user feedback. Integrating reliability considerations into your product team’s workflow can produce better outcomes and seamless deployments.
It's great that you're already handling CI/CD! To further enhance your DevOps skills, dive deeper into networking and Linux systems management. These are crucial areas to master. Also, for Prometheus and Grafana, I'd recommend starting with at least 4GB of RAM and more disk space. It’ll help with performance as your usage grows. Since you're on AWS, utilizing their services for scaling could be beneficial too. Remember, monitoring is key in a production environment.
For running Prometheus and Grafana, consider using Amazon ECS or another container service. They are designed to streamline deployment and scaling for containerized applications. This will simplify your infrastructure management and make things more efficient.
Absolutely, deploying on a single EC2 instance can lead to a single point of failure, which isn't ideal for high availability. Familiarizing yourself with VPCs and setting up private/public subnets is important to enhance security. It seems like you're on the right track wanting them as part of your architecture. Think about exploring auto-scaling groups (ASGs) as well; they can provide automatic scaling capabilities based on traffic.
