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.

You restrict access by using security groups and private subnets for all your resources. All of the monitor logs, VPC Flow Logs, and CloudTrails are active. IAM policies are enforced, everything is correctly secured, and nothing is exposed. This is because you have the VPN service to access any resources. However, if you want to provide an internet service, you have to open at least one point of access to the external world. As we already discussed in the VPC Subnets section, you should expose as few resources in the public subnet as possible, with the security group rule open. If possible, only an ELB should stay in this situation, passing connections to the EC2 machines in private subnets, since the EC2 machines communicate with the RDS databases with strict security rules. 

This is the most classic AWS application, and it is not necessary to explain it in detail here. Instead, we want to focus on increasing the security of the ELB with the AWS WAF. For more information...
