Overview of this book

Amazon Web Services (AWS) is a bundled remote computing service that provides cloud computing infrastructure over the Internet with storage, bandwidth, and customized support for application programming interfaces (API). Implementing these services to efficiently administer your cloud environments is a core task. This book will help you build and administer your cloud environment with AWS. We’ll begin with the AWS fundamentals, and you’ll build the foundation for the recipes you’ll work on throughout the book. Next, you will find out how to manage multiple accounts and set up consolidated billing. You will then learn to set up reliable and fast hosting for static websites, share data between running instances, and back up your data for compliance. Moving on, you will find out how to use the compute service to enable consistent and fast instance provisioning, and will see how to provision storage volumes and autoscale an application server. Next, you’ll discover how to effectively use the networking and database service of AWS. You will also learn about the different management tools of AWS along with securing your AWS cloud. Finally, you will learn to estimate the costs for your cloud. By the end of the book, you will be able to easily administer your AWS cloud.

Preface

Creating a load balancer


AWS offers two kinds of load balancers:

  • Classic load balancer
  • Application load balancer

We're going to focus on the application load balancer. It's effectively an upgraded, second generation of the ELB service, and it offers a lot more functionality than the classic load balancer. HTTP/2 and WebSockets are supported natively, for example. The hourly rate also happens to be cheaper.

Note

Application load balancers do not support layer-4 load balancing. For this kind of functionality, you'll need to use a classic load balancer.

How to do it...

  1. Open up your text editor and create a new CloudFormation template. We're going to require a VPC ID and some subnet IDs as Parameters. Add them to your template like this:
      AWSTemplateFormatVersion: '2010-09-09' 
      Parameters: 
        VPCID: 
          Type: AWS::EC2::VPC::Id 
          Description: VPC where load balancer and instance will launch 
        SubnetIDs: 
          Type: List<AWS::EC2::Subnet::Id> 
      ...
