Infrastructure as a Service
AWS CloudFormation
In today’s digital cloud-native era, infrastructure as code (IAC) is a critical part of ensuring consistency and reusability.
Most public providers have a version of IaC they offer; for AWS, it is CloudFormation.
CloudFormation helps you model your resources by describing them in a template that can be deployed as a stack on AWS. With CloudFormation, you can go from creating resources from the console to automating complex architecture on demand. Let’s get started with the basics of AWS CloudFormation.
In the simplest terms, managing a complex application’s resources will become a problem for developers. It would be a difficult task to monitor and manage every single resource in the application.
AWS CloudFormation came in to solve this problem and did it seamlessly. AWS CloudFormation provides a common platform and language that can be used to describe and provision all the AWS infrastructure resources and services in a cloud environment.
Benefits
- It’s just code and an easy-to-read template.
CloudFormation Templates are just a code written in YAML / JSON, which makes it very simple and easy to read, understand, and modify with basic knowledge.
2. Improved Automation
The developer doesn’t have to care about provisioning resources, he only needs to make his application better. All the provisioning and management of resources will be taken care of by CloudFormation. The simplicity of the template allows developers to declare what the desired resources should look like. This eliminates the need to rely on other scripting tools to create the resources.
3. Model it all and Quick Infrastructure Replication with Infrastructure consistency
This is the best part of CloudFormation. You can model an entire AWS infrastructure in a text file and use that template to build multiple infrastructures using a single code.
The declarative way of defining templates allows for consistency—the developer can be assured that stacks created with the template will be identical.
4. Extensibility
Using AWS Lambda, developers can create their own extensions and add them to the CloudFormation template. The CloudFormation stack provides an extensible mechanism to make this possible. Custom provisioning of extensions can be made for a third-party resource.
5. Safety controls
There are no manual steps or steps that lead to an error (human errors). The controls are automated to reduce effort and increase quality and performance.
