Overview of this book

Amazon Web Services (AWS) provides trusted,cloud-based solutions to help you meet your business needs. Running your solutions in the AWS Cloud can help you get your applications up and running faster while providing the security to meet your compliance requirements. This book begins by familiarizing you with the key capabilities to architect and host applications, websites, and services on AWS. We explain the available options for AWS free tier with virtual instances and demonstrate how you can launch and connect them. Using practical examples, you’ll be able to design and deploy networking and hosting solutions for large deployments. Finally, the book focuses on security and important elements of scalability and high availability using AWS VPC, Elastic Load Balancing, and Auto scaling. By the end of this book, you will have handson experience of working with AWS instances,VPC, Elastic Load Balancing, and Auto scalingrelated tasks on Amazon Web Services.

Chapter 5. Creating a VPC

In Chapter 4, Networking on AWS, we discussed networking on AWS, which laid the foundation for being able to create our own VPCs. We discussed IP addressing, subnets, and route tables. In this chapter, we will learn several methods to build, secure, and connect to a VPC. First, we're going to look at classic EC2s, which are instances that are launched outside of a VPC. Then, we'll talk about the VPC that AWS already creates for you, the default VPC. Next, we'll demonstrate creating a VPC, using the VPC Wizard, and then creating one from scratch. After that, we'll talk about several ways to connect to the instances in your VPC, and then we'll make your VPCs more secure by introducing network access control lists and Bastion instances.

Finally, we'll discuss making your architectures highly available by leveraging multiple availability zones, load balancing, and auto scaling.

The main topics that we will cover are as follows:

  • VPC EC2s versus classic EC2s
  • The default VPC...
