Deployment Services

Cloudformation

CloudFormation Essentials

- CloudFormation is the pure definition of infrastructure as code:

-- You can “convert” your application’s architecture into a JSON formatted template (so your architecture is literally code)

-- You can then use that JSON template to deploy out updated or replication copies of that architecture to multiple regions

Benefits

- Saves time - you don’t have to manually create duplicate architecture in additional regions

- Since your infrastructure is now code, you can version control your infrastructure. Allowing for rollbacks to previous versions of your infrastructure if a new version has issues

- Allows for backups of your infrastructure

- Great solution for disaster recovery

Elastic BeanStalk

Elastic BeanStalk Essentials:

- Elastic Beanstalk is designed to make it easy to deploy less complex applications

- This helps reduce the management required for building and deploying applications

- Elastic Beanstalk is used to deploy out easy, single-tier applications that take advantage of core services such as:

-- EC2

-- Auto Scaling

-- ELB

-- RDS

-- SQS

-- CloudFront

- Why/when to use Elastic Beanstalk:

-- In order to quickly provision an AWS environment that requires little to no management

-- The application fits within the parameters of the Beanstalk service

-- Can deploy from repositories or from uploaded code files

-- Easily update applications by uploading new code files or requesting a pull from a repository

- Supported Platforms:

-- Docker

-- Java

-- Windows .NET

-- Node.js

-- PHP

-- Python

-- Ruby

Quiz: Deployment Quiz

Q: What platforms are supported in Elastic BeanStalk?

A: Docker, Java, Windows .NET, Node.js, PHP, Python, Ruby

T: Elastic BeanStalk is primarily used to deploy simple, single-tier applications.

Q: What are two benefits of Cloudformation?

A1: A great disaster recovery option

A2: Version control your infrastructure

E: Since CloudFormation allows for you to turn your infrastructure into code, you can use it to quickly spin up the infrastructure in a new region (in the case of a disaster), and since it's code, you can version control it.

T: By using Cloudformation, you can easily rollback your application's infrastructure to previous versions.

Q: What AWS service allows you to treat your infrastructure as code?

A: Cloudformation

E: Cloudformation allows you to turn your infrastructure into JSON-formatted templates.
