Developers have created a new application for a multinational pharma company.
This application is tested successfully on EC2 instance in the us-west-1 region & now needs to be deployed in the Production environment across the globe.
As a SysOps Administrator you need to deploy this application for all accounts within this company & ensure identical configuration across all regions.
Whichof the following is a cost-effective and efficient way to have applications deployed in a short time frame?
Click on the arrows to vote for the correct answer
A. B. C. D.Correct Answer: B.
With AWS CloudFormation StackSets, stacks can be created in multiple AWS accounts in different regions using a single AWS CloudFormation Template.
In this template, resources are defined along with all parameters.
This StackSet can be used to create, update & delete stacks in multiple accounts across regions.
Option A is incorrect as manual configuration will result in additional admin work & deploying on a large number of instances will be a tedious and time-consuming task.
Option C is incorrect as creating scripts can be error prone & will need additional efforts to validate all scripts before deployment.
Option D is incorrect as using a third-party tool will incur additional costs.

AWS CloudFormation StackSets is a service that enables you to create, update, or delete stacks across multiple accounts and regions with a single CloudFormation template. It simplifies the management of your infrastructure and applications by providing a unified way to manage resources across your organization.
By using StackSets, you can deploy your application to multiple regions in a single action, saving you time and effort. Additionally, StackSets ensure that all deployed instances are identical, which guarantees consistency across regions, reducing errors and ensuring better security.
Option A, manually configuring the application on EC2 instances in all regions, is time-consuming, error-prone, and requires a high level of expertise, making it a costly and inefficient approach.
Option C, creating a script to automatically deploy the application while launching EC2 instances in all regions, may be a viable option, but it requires a considerable amount of development time and expertise, and it may not be as scalable as StackSets.
Option D, using third-party tools to automate deployment of applications on EC2 instances in all regions, is not recommended unless the tools are thoroughly evaluated for security, reliability, and compatibility with AWS services. It may also incur additional costs and complexity to integrate with existing infrastructure and workflows.
In summary, AWS CloudFormation StackSets provide a scalable, secure, and cost-effective solution to deploy applications to multiple regions within a short time frame while ensuring consistency across regions.
