EC2 Container Service (ECS)
Amazon EC2 Container Service (Amazon ECS) is a highly scalable, fast, container management service that makes it easy to run, stop, and manage Docker containers on a cluster of Amazon Elastic Compute Cloud (Amazon EC2) instances. Amazon ECS lets you launch and stop container-based applications with simple API calls, allows you to get the state of your cluster from a centralized service, and gives you access to many familiar Amazon EC2 features
AD Connector – uses your existing on-premises Microsoft Active Directory to access AWS applications and services
Simple AD – is a Microsoft Active Directory – compatible directory that is powered by Samba 4 and hosted on the AWS cloud.
Simple AD is the least expensive option and your best choice if you have 5,000 or less users and don’t need the more advance Microsoft Active Directory

Terraform is a tool for building, changing, and versioning infrastructure safely and efficiently. Terraform can manage existing and popular service providers as well as custom in-house solutions.
idempotent
Terraform have three files with “tf” extension (Terraform extension):
This makes it possible to use a value returned as a parameter for another function later.
1.Download terraform

Terraform state storage ( local vs remote)
2. Terraform commnads
terraform version
terraform init
terraform fmt
terrafom validate
terraform plan
terraform apply ( Deploy )
terraform apply -auto-aprove
terraform modules
configure Terraform backend – AWS S3 backend with Terraform
3. Configure Terraform on AWS

Refreshing Terraform state in-memory prior to plan…
The refreshed state will be used to calculate this plan, but
will not be persisted to local or remote state storage.
The Terraform execution plan has been generated and is shown below.
Resources are shown in alphabetical order for quick scanning. Green resources
will be created (or destroyed and then created if an existing resource
exists), yellow resources are being changed in-place, and red resources
will be destroyed. Cyan entries are data sources to be read.
Note: You didn’t specify an “-out” parameter to save this plan, so when
“apply” is called, Terraform can’t guarantee this is what will execute.

infrastructure, so keep it safe. To inspect the complete state
use the `terraform show` command.
