Learn Kubernetes with The Kubernetes Book by Nigel Poulton: A Comprehensive Guide for 2021
The Kubernetes Book Nigel 13: A Review
The Kubernetes Book Nigel 13 is a book that aims to teach you everything you need to know about Kubernetes, the popular platform for deploying and managing containerized applications. Whether you are a beginner or an expert, this book will help you understand the core concepts, architecture, and features of Kubernetes, as well as how to use it in real-world scenarios. In this article, we will review the book and its author, Nigel Poulton, and see how it can help you master Kubernetes.
What is Kubernetes and why should you learn it?
Kubernetes is an open-source system that automates the deployment, scaling, and management of containerized applications. It was originally developed by Google, based on their experience of running billions of containers per week. It is now maintained by the Cloud Native Computing Foundation (CNCF) and supported by a large community of contributors and users. Kubernetes has many benefits for cloud-native applications, which are applications that are designed to run on distributed systems using microservices architecture. Some of these benefits are: - Portability: Kubernetes allows you to run your applications on any cloud platform or your own data center, without changing your code or configuration. You can also migrate your applications across different environments with ease. - Scalability: Kubernetes can automatically scale your applications up or down based on the demand or resource availability. You can also define horizontal or vertical scaling policies for your applications based on metrics or events. - Reliability: Kubernetes ensures that your applications are always available and resilient to failures. It can restart crashed containers, reschedule them to healthy nodes, balance the load across nodes, and perform rolling updates without downtime. - Efficiency: Kubernetes optimizes the utilization of your resources by packing multiple containers on a single node, reducing the overhead of running multiple virtual machines. It also allows you to specify resource limits and requests for your containers, ensuring fair allocation and preventing starvation or contention. Kubernetes is one of the most popular and widely used platforms for cloud-native applications. According to the CNCF survey in 2020, 83% of respondents use Kubernetes in production, up from 58% in 2018. Learning Kubernetes can help you develop, deploy, and manage modern applications that are scalable, reliable, and efficient.
The challenges of Kubernetes and how to overcome them
Kubernetes is not without its challenges. Some of these challenges are: - Complexity: Kubernetes has a steep learning curve and requires a lot of knowledge and skills to use it effectively. It has many components, concepts, objects, and commands that you need to understand and master. It also has many configuration options and parameters that you need to tune and optimize for your specific use cases. - Security: Kubernetes exposes a large surface area for potential attacks and vulnerabilities. You need to secure your cluster, your nodes, your containers, your network, your data, and your access. You also need to comply with the security policies and regulations of your organization and industry. - Maintenance: Kubernetes requires constant monitoring and maintenance to ensure its health and performance. You need to keep track of the status and metrics of your cluster, nodes, pods, services, and other resources. You also need to update and patch your Kubernetes version and components regularly to fix bugs and vulnerabilities. To overcome these challenges, you need a reliable and comprehensive source of information and guidance that can help you learn and master Kubernetes. This is where The Kubernetes Book comes in.
