Where do I start with DevOps as a beginner on DigitalOcean?

Question

I am a backend developer who recently started using DigitalOcean to host my projects. I can deploy a basic app on a Droplet but I feel like I am missing a lot of fundamentals around things like CI/CD, infrastructure as code, monitoring, and security hardening.

Is there a recommended learning path or roadmap for someone who wants to get serious about DevOps? Not sure where to focus first or what order makes sense.

Hi there, The order you learn things in matters more than most people think, and jumping straight to Kubernetes or Terraform before you have the fundamentals down is a common mistake. A rough order that makes sense for someone already comfortable with Droplets: Start with Linux fundamentals if you have any gaps. SSH, file permissions, process management, and systemd are things you will use every single day. Then move into networking basics: how DNS works, firewalls, reverse proxies with Nginx, and SSL certificates. From there, version control workflows and basic CI/CD. GitHub Actions is a good starting point since it is free and integrates easily with DigitalOcean deployments. Get comfortable with automated testing and deployment pipelines before touching infrastructure as code. Infrastructure as code comes next. Terraform works well with DigitalOcean and has good documentation. Start small, manage a Droplet and a firewall with it, then expand from there. Monitoring and observability is something people leave too late. DigitalOcean has built in metrics, but learning how to set up alerting, log aggregation, and uptime monitoring early saves you a lot of pain in production. Security hardening runs through all of it, not a separate step. Things like disabling root SSH, setting up fail2ban, keeping packages updated, and using firewall rules properly should be habits from day one. If you want a structured roadmap that covers all of this in order, this one is worth bookmarking: https://devops-daily.com/roadmap DigitalOcean’s own tutorials are also excellent for the hands-on parts: https://www.digitalocean.com/community/tutorials

Hey, @72e571841e7f4a6881090a2f3e93c0 I think the biggest mistake people make when getting into DevOps is jumping straight into Kubernetes and advanced tooling before really understanding Linux, networking, deployments, and automation. Since you can already deploy apps on a Droplet, I’d focus first on learning how to make deployments reproducible and reliable. Things like Docker, CI/CD with GitHub Actions, basic server hardening, monitoring with Prometheus and Grafana, and infrastructure as code using Terraform will teach you much more than just spinning up servers manually. What helped me understand DevOps better was treating servers as something disposable and automated instead of “pets” I SSH into and configure manually. Once you can recreate your infrastructure, deploy automatically from Git, monitor failures, and recover quickly when something breaks, that’s when everything starts to click. The roadmap Bobby mentioned is solid. Regards
