I'm currently a networking student with a growing interest in backend service deployments. I know that understanding modern software systems is crucial since they underpin much of the internet. I'm trying to get a grasp on DevOps architecture, and here's what I think I understand so far: modern applications usually operate in cloud data centers on virtual machines. These VMs host multiple services using containerized environments, which help manage network segmentation for security. Services communicate with cloud databases and are supported by load balancers to efficiently handle traffic. DDoS protection is typically managed at the cloud level instead of the internal service networks.
I'm looking for guidance on what I should focus on studying before diving deeper. Any book recommendations, labs, or videos that can help demystify real-world DevOps for a beginner would be greatly appreciated!

Kubernetes is a big player in this field, definitely worth checking out!
Just a heads up—calling yourself a 'raw networking student' might not resonate well in the industry anymore. You might want to rephrase that when discussing your journey!
In your first few years, aim to work at multiple companies to experience different technologies and deployment philosophies. The real learning happens in actual production environments. Don’t chase the highest salary—sometimes a pay cut for a more enriching experience pays off in knowledge!
You can also consider running applications on bare metal directly or using VMs. In a cloud setting, many folks provision VMs on platforms like AWS or GCP and run multiple instances per host. The key is to install your apps on OS directly or leverage containers for environment isolation, ensuring consistency across development and production. An orchestrator like Kubernetes or Docker Swarm is essential for managing these containers at scale. If you're keen, try installing a Linux distribution like Ubuntu and play with Docker to get a hands-on feel! Also, for networking basics, check out Beej's guide—it’s a great resource for understanding the underlying networking principles!
