Learning Windows Server Containers

Overview of this book

Windows Server Containers are independent, isolated, manageable and portable application environments which are light weight and shippable. Decomposing your application into smaller manageable components or MicroServices helps in building scalable and distributed application environments. Windows Server Containers have a significant impact on application developers, development operations (DevOps) and infrastructure management teams. Applications can be built, shipped and deployed in a fast-paced manner on an easily manageable and updatable environment. Learning Windows Server Containers teaches you to build simple to advanced production grade container based application using Asp.Net Core, Visual Studio, Azure, Docker and PowerShell technologies. The book teaches you to build and deploy simple web applications as Windows and Hyper-V containers on Windows 10 and Windows Server 2016 on Azure. You will learn to build on top of Windows Container Base OS Images, integrate with existing images from Docker Hub, create custom images and publish to Hub. You will also learn to work with storage containers built using Volumes and SQL Server as container, create and configure custom networks, integrate with Redis Cache containers, configure continuous integration and deployment pipelines using VSTS and Git Repository. Further you can also learn to manage resources for a container, setting up monitoring and diagnostics, deploy composite container environments using Docker Compose on Windows and manage container clusters using Docker Swarm. The last chapter of the book focuses on building applications using Microsoft’s new and thinnest server platform – Nano Servers.

Preface

Chapter 8. Container Network

An application consists of many layers such as data repository layer, business component layer and a web layer which basically forms the interacting surface for the user. Each of these layers are typically deployed using a multi-subnet secured network topology so that communication across layers can be controlled individually at a subnet level. Every application is designed keeping the network topology, scalability and extensibility features in mind but, during the normal course of application development, these features are hardly tested. This is due to the time and effort required for setting up the required infrastructure. Developers test the application in isolation using a single instance without the network restrictions applied. During this cloud era, it is important for applications to be tested (at least occasionally) in a near production-like environment so that the security, scalability and performance expectations match the real environments. Testing...
