AWS CloudTrail is a service that enables governance, compliance, operational auditing, and risk auditing of your AWS account.

AWS provides SDKs for most programming languages along with development tools to manage version control, manage continuous integration and continuous delivery, build code and even deploy code.

AWS SDKs

AWS provide SDKs for following programming languages or platforms:

• Android

AWS Elastic Beanstalk is an easy-to-use service for deploying and scaling web applications. You simply upload your code and Elastic Beanstalk automatically handles the deployment, from capacity provisioning, load balancing, auto-scaling to application health monitoring. You still retain full control over the AWS resources powering your application and can access the underlying resources at any time.

A template is a JSON- or YAML-formatted text file that describes your AWS infrastructure. Example template for an EC2 instance in a security group is available here.

CloudFormation gives an easy way to create a collection of related AWS resources and provision them in an orderly and predictable way. CloudFormation automates and simplifies the task of repeatedly and predictably creating groups of related resources.

We will configure and demo the use of CloudFront with an S3 bucket as the origin. This note assumes that you have setup your AWS account and are familiar with using S3.

Steps:

1. Create an S3 bucket in a region far from your region, keeping all defaults.

We already created a EC2 server setup and tried few routing policies. We deleted those A records. We will create one with failover policy now. We will also need to create health check within route 53 for this. This policy lets you chose where traffic will be sent based on geographical location of users.

Steps:

We already created a EC2 server setup and tried few routing policies. We deleted those A records. We will create one with failover policy now. We will also need to create health check within route 53 for this. Use this policy when you want an active/passive setup.

Steps:

1. Copy your ELB dns address and go back to Route 53

We already created a EC2 server setup and configured and uses simple routing policy. We deleted those A records. We will create one with latency policy now. This policy allows you to route based on lowest latency for end user (e.g. which region will give fastest response time).
