Networking for DevOps: Key Concepts Every Engineer Should Know
As a DevOps engineer, you know that the success of any application depends not only on the code but also on the infrastructure that supports it. Networking plays a crucial role in ensuring that your application can communicate with other services, scale effectively, and remain secure. In this article, we’ll explore some key networking concepts that every DevOps engineer should know.
TCP/IP
TCP/IP is the backbone of the internet and forms the basis of all network communication. Understanding how TCP/IP works is essential for troubleshooting network issues and optimizing application performance. TCP (Transmission Control Protocol) breaks data into packets, sends them across the network, and ensures they are reassembled correctly on the receiving end. IP (Internet Protocol) is responsible for routing the packets to their intended destination.
DNS
DNS (Domain Name System) translates human-readable domain names into IP addresses, enabling users to access websites and services without needing to remember a string of numbers. As a DevOps engineer, you’ll need to understand how DNS works, how to configure DNS servers, and how to troubleshoot DNS issues.
