Effective DevOps with AWS - Second Edition

Overview of this book

The DevOps movement has transformed the way modern tech companies work. Amazon Web Services (AWS), which has been at the forefront of the cloud computing revolution, has also been a key contributor to the DevOps movement, creating a huge range of managed services that help you implement DevOps principles. Effective DevOps with AWS, Second Edition will help you to understand how the most successful tech start-ups launch and scale their services on AWS, and will teach you how you can do the same. This book explains how to treat infrastructure as code, meaning you can bring resources online and offline as easily as you control your software. You will also build a continuous integration and continuous deployment pipeline to keep your app up to date. Once you have gotten to grips will all this, we'll move on to how to scale your applications to offer maximum performance to users even when traffic spikes, by using the latest technologies, such as containers. In addition to this, you'll get insights into monitoring and alerting, so you can make sure your users have the best experience when using your service. In the concluding chapters, we'll cover inbuilt AWS tools such as CodeDeploy and CloudFormation, which are used by many AWS administrators to perform DevOps. By the end of this book, you'll have learned how to ensure the security of your platform and data, using the latest and most prominent AWS tools.

  • AWS Elastic File System ( In a few words, this is a network file system that is mounted in your EC2 machine with virtually infinite space where you only pay for the space used by your file.

  • AWS S3 ( This was the first AWS service on the market and is an object storage designed to deliver 99.999999999% durability.

In general, the S3 should be your favorite solution, but it is not always applicable because it requires application software change to use it. Consequently, in some cases, you may need an alternative that you can leverage on EFS. 

The world is full of software and plugins designed around S3. For example, WordPress saves the files...
