Nowadays, as a system integrator and an agency Xtremax leverage the traditonal architecture into the cloud ecosystem. It's including the how we manage the current project and upcoming project to build an ecosystem on AWS. There are many AWS features can be used to help the migration and operation process running smoothly. One of them is AWS CloudFormation.
On the managed service itself, we want to minimize the manual touch on every system to minimize the error caused by the human. In this case, Xtremax use CloudFormation to execute customer request related to updating the resources on AWS.
CloudFormation
How CloudFormation Works
In order for AWS CloudFormation to work as shown on the picture above, it is important to create a stack. AWS CloudFormation is effective when resources are provisioned and configured for various use cases. For example, EC2 instances created using CloudFormation require permissions. Similarly, there is a requirement for permissions that limit the creation of instances once a stack is deleted.
Therefore, there is a requirement to use AWS Identity and Access Management (IAM) to monitor, control and manage permissions. Hence, it is important to create a template that automates the authority and function of CloudFormation.
Creating Code Infrastructure
We create Infrastructure from the beginning using code by using JSON format. All of the code will be created by our DevOps engineer following the customer request on particular resources. The Devops usually use their predefined template to make it lot easier then to write from scratch.
Save code into AWS S3
The code then will be uploaded to the S3 bucket, so other DevOps engineer can also access the code when they needed.
AWS CloudFormation
At first, to create CloudFormation stack Devops will describing the exact location of the template, in this case it uses S3 location. So, they will put the AWS S3 URL as the location of the template.
Secondly, they determine any parameters in the template and specify input values. It will helps them while creating the stack.
Thirdly and most importantly, enable parameters to help pass in values. It allows devops to easily customize resources while creating the stack.
Output of the Process
CloudFormation allocates and configures resources by approaching AWS. The use cases and functions of the AWS CloudFormation are mentioned in the template. Moreover, these use cases and functions arrange the stacks and resources for the template to help operate AWS CloudFormation.
CloudFormation on CWP
On CWP, the Devops use CloudFormation stack to provision and update customer resources, such as Lambda Node, RDS, EC2 instances, Network Virtual appliance, and many more. Since the DevOps use CloudFormation during the maintenance, they can save enough time to do another task. From the business perspective, it can reduce the estimated waiting time for customers to get their requests finished and increase customer satisfaction.
