"Mastering Go Network Administration" is a structured beginning for network administrators looking to improve network efficiency, scalability, and security. This book provides a one-stop solution for all of your network administration needs, with comprehensive coverage of automation, security, containerization, monitoring, and performance testing.
Beginning with the fundamentals of creating a network automation lab with the EVENG network simulator and the Go programming language, readers will learn the step-by-step process of installing EVE-NG, followed by the importance of service mesh in automation and how it can simplify network operations.
The book delves deeply into critical topics such as deploying ingress controllers and implementing service mesh with Linkerd. Readers will learn about container-native storage, container storage management with Docker, and automated SSL certificates, firewall configuration, and network policies. Monitoring and performance tuning are also covered in the book, including how to monitor container performance and automatically roll out updates. The book covers a series of performance testing strategies like load testing, stress testing, and scalability testing. It shows readers how to find performance bottlenecks and optimise their network with the help of tools like Vegeta and Apache JMeter through the use of real-world examples.
Go, also known as Golang, is a programming language that was developed by Google in 2007. It is an open-source language that was designed with the goal of simplifying the process of developing high-performance network applications. The language's syntax is simple and easy to learn, and it is known for its efficiency, scalability, and reliability. Due to these features, Go has become increasingly popular for network programming and network automation. Network programming refers to the development of applications that communicate over a network. These applications can include web servers, microservices, and other network-based services.
Go provides a number of features that make it well-suited for network programming. These features include:
- Concurrency: Go has built-in support for concurrency, which allows developers to write applications that can handle multiple tasks simultaneously. This is particularly useful for network programming, where applications need to handle multiple requests and responses at the same time.
- Garbage collection: Go has an efficient garbage collector that automatically frees up memory that is no longer in use. This feature makes it easy for developers to write network applications without worrying about memory management.
- Standard library: Go comes with a comprehensive standard library that includes packages for handling networking, encryption, and other common tasks. This makes it easy for developers to write network applications without having to rely on third-party libraries.
- Error handling: Go has a robust error handling mechanism that makes it easy for developers to write applications that can handle errors gracefully. This is particularly important for network applications, which may encounter errors due to network connectivity issues.
In addition to these features, Go also has a number of tools and frameworks that make it easy to write network applications. These include:
- The net package: The net package in Go provides a set of tools for handling networking tasks such as creating TCP and UDP sockets, and performing DNS lookups.
- Goroutines: Goroutines are lightweight threads that make it easy to write concurrent applications in Go. They allow developers to handle multiple tasks at the same time without the need for complex threading code.
- Channels: Channels in Go provide a mechanism for communicating between goroutines. They make it easy to write applications that coordinate multiple tasks.
- Third-party libraries: Go has a vibrant ecosystem of third-party libraries that make it easy to write network applications. Some popular libraries include the Gorilla web toolkit, the Gin web framework, and the Colly web scraping library.
Key Learnings:
Setting up an EVE-NG network simulator, VIM IDE, kubeadm, and a comprehensive network automation lab to improve network efficiency, scalability, and security.
Configuring ports, hosts, and servers using Go scripting to streamline network automation.
Writing, testing, and validating network automation scripts to ensure smooth and reliable network administration.
Building Docker images, running containers, and managing container deployments for efficient containerization.
Automating load balancing, firewall configuration, and Kubernetes network policies for seamless network management.
Working with popular tools such as Puppet, Zookeeper, Traefik, Envoy, and various Go networking packages.
Automating SSL setup, container storage, container performance monitoring, and rolling updates.
Using powerful load testing tools like Vegeta and Apache JMeter for efficient load testing, stress testing, and scalability testing to identify and eliminate performance bottlenecks.
