Overview of this book

AWS is an on-demand remote computing service providing cloud infrastructure over the internet with storage, bandwidth, and customized support for APIs. This updated second edition will help you implement these services and efficiently administer your AWS environment. You will start with the AWS fundamentals and then understand how to manage multiple accounts before setting up consolidated billing. The book will assist you in setting up reliable and fast hosting for static websites, sharing data between running instances and backing up data for compliance. By understanding how to use compute service, you will also discover how to achieve quick and consistent instance provisioning. You’ll then learn to provision storage volumes and autoscale an app server. Next, you’ll explore serverless development with AWS Lambda, and gain insights into using networking and database services such as Amazon Neptune. The later chapters will focus on management tools like AWS CloudFormation, and how to secure your cloud resources and estimate costs for your infrastructure. Finally, you’ll use the AWS well-architected framework to conduct a technology baseline review self-assessment and identify critical areas for improvement in the management and operation of your cloud-based workloads. By the end of this book, you’ll have the skills to effectively administer your AWS environment.

Creating a key pair

A key pair is used to access your instances via SSH. Key pairs are an integral part of asymmetrical cryptography and are an encryption technique that makes use of two non-identical keys to encrypt and decrypt data. A user's public key can be shared freely, and data that is encrypted with the public key can only be decrypted with the private key. When you create a key pair with EC2, the key can be associated with any number of instances, and you download a .pem file, which is similar to a .ppk file in Putty or an id_rsa file on Linux machines.
