Introduction to Amazon CloudFormation and its use cases

Recipe Objective - Introduction to Amazon CloudFormation and its use cases?

The AWS CloudFormation is widely used and is defined as a service that helps users model and set up the AWS resources so that users can spend less time managing those resources and more time focusing on applications that run in the Amazon Web Services. Users can create the template which describes all the AWS resources that users want (like the Amazon EC2 instances or the Amazon RDS DB instances) and CloudFormation takes care of the provisioning and configuring those resources for its users. The AWS resources are not needed to individually be created and configured and ist important to figure out what's dependent on what so, the CloudFormation handles that. Amazon CloudFormation can also be defined as an infrastructure automation or the Infrastructure-as-Code (IaC) tool and a cloud automation solution as it can automate the setup and deployment of many Infrastructure-as-a-Service (IaaS) offerings on the AWS CloudFormation that supports virtually every service that runs in Amazon Web Services. Amazon CloudFormation templates can also be applied to the AWS services which cater to niche use cases like Ground Station and the AWS satellite management solution. Further, if a service runs on AWS, it is a safe bet that a user can use CloudFormation to automate configuration and deployment.

Benefits of Amazon CloudFormation

The Amazon CloudFormation templates when created will enable the deployment of multiple instances of the same resources almost instantaneously using just one template. This approach leads to much faster deployment than a user can achieve if a user had to manually set up each deployment by running commands on the CLI or pressing buttons in the AWS console thus it offers fast Deployment speed. The Amazon CloudFormation templates are useful because they ensure that users can scale their environment up quickly when the time comes. So, by keeping CloudFormation templates on hand, more virtual machine instances can be added or storage space, for example, at a moment's notice if an applications experience increased traffic it needs to scale the environment up thus offering Scale-up benefit. When Amazon CloudFormation templates are used to define and deploy AWS resources, the same can be applied precisely and repeatedly. In this way, CloudFormation ensures that the applications and services will be consistent and identical, no matter how many instances are created and thus offers Consistency. A single CloudFormation template can manage the deployment of individual services or resources and multiple resources and this management ability enables integration of different AWS cloud services such as a template which is written, that sets up an EC2 virtual machine within an AWS Virtual Private Cloud (VPC) or deploys an S3 storage bucket and further configures access control for it using IAM service and thus offers Service Integration.

System Requirements

  • Any Operating System(Mac, Windows, Linux)

This recipe explains Amazon CloudFormation and Use cases of Amazon CloudFormation.

Use cases of Amazon Elastic Block Storage

    • It provides the management of infrastructure with DevOps.

Amazon CloudFormation helps in automating, testing, and deploying infrastructure templates with continuous integration and delivery (CI/CD) automation.

    • It helps in Scaling production stacks.

Amazon CloudFormation enables users to run anything from the single Amazon Elastic Compute Cloud (EC2) instance to a complex multi-region application.

    • It helps in sharing best practices.

Amazon CloudFormation defines the Amazon Virtual Private Cloud (VPC) subnet or provisioning services like AWS OpsWorks or Amazon Elastic Container Service (ECS) with ease.

    • It provides Easy updates.

Amazon CloudFormation enables users to deploy new resources, in addition, to applying changes to existing resources with the CloudFormation templates. This ability of Amazon CloudFormation simplifies the process of, such as adding more storage to a fleet of EC2 instances or changing the access control rules.

    • It provides Auditing and change management.

Amazon CloudFormation helps in tracking changes based on which templates users have applied and how they change over time. Change tracking in CloudFormation means that users will be able to determine how the AWS services and resources have changed over time without looking through the logs to reconstruct the timeline of updates.
