PowerShell, originally developed by Microsoft, is a popular scripting language. With the cloud infrastructure addition and the heterogonous environment, there is a high degree of complexity in the IT environment. Without automating your routine task, it is practically impossible to keep the required governance, compliance, and control in your IT shop. Though there are many scripting tools available on the market that you can make use of to automate your workload, PowerShell stands out from others. With increasing complexity in the IT environment, you need a tool that can provide you a single pane to work with multiple cloud and hybrid environments. PowerShell provides you with that unified experience. It is a command-line and scripting language. Most of the industry-leading product creators have a module for PowerShell that can work with their product, whereas this is not the case with other tools. PowerShell is object-based, and this gives the incredible flexibility to filter, sort, measure, group, compare, or take other actions on objects as they pass through the PowerShell pipeline. Last year, Microsoft announced that PowerShell 6 is open source and will support Linux, macOS, and other platforms in addition to Windows. That makes PowerShell an even stronger candidate for providing universal shell to work in multicloud, hybrid, and heterogeneous environments.
In this book, we will explore how you can interact and work with many AWS services via PowerShell. We will learn how we can build highly available and fault-tolerant applications using Elastic Load Balancer and Auto Scaling. In addition, we will learn how Elastic Beanstalk and CloudFormation will help you to deploy the AWS infrastructure and application. We will also touch upon the popular MySQL Relational Database Service and learn how to spin up and work with DB Instances. Finally, we will learn about built-in monitoring and auditing capabilities that you should always consider in your AWS infrastructure.
