Leveraging Amazon Cloud Formation for Seamless AWS Deployments

No comments

What exactly is the Amazon Web Services CloudFormation?

AWS, A service known as CloudFormation is designed to assist you in modelling and configuring your Amazon Web Services (AWS) resources. This allows you to devote less effort to maintaining those resources and more time to concentrating on your applications that are hosted on AWS. After you have created a template that outlines all of the Amazon Web Services (AWS) resources that you require (such as Amazon EC2 instances or Amazon RDS DB instances), CloudFormation will take care of deploying and configuring those resources for you. CloudFormation takes care of tasks such as creating and configuring Amazon Web Services (AWS) resources on an individual basis and determining which resources are dependent on which elements. Several examples are provided below to illustrate how CloudFormation can be of use.

Streamline the management of the infrastructure. 

Consider utilizing an automated scaling group, an Elastic Load Balancing load balancer, and an Amazon Relational Database Service database instance in order to create a web application that is not only scalable but also incorporates a backend database. It is possible that you will use every single service to provide these resources; however, only after you have created the resources will you need to configure them so that they may collaborate with one another. It is possible that all of these tasks will add complication and time to the process beforehand you even get your program up and running. You might, as an alternative, either construct a CloudFormation template from scratch or edit a current one. You can describe all of the resources you have and the properties they possess using a template. When you use the provided template to create a CloudFormation stack, CloudFormation will automatically provision the Auto Scaling group, load balancer, and database for you. Each of your Amazon Web Services (AWS) resources will become operational once the stack of resources has been successfully established. Just as quickly, you can delete the stack, which will also erase all of the resources that are contained within the stack. Through the utilization of CloudFormation, it is readily possible to manage a group of resources as a single entity.

Replicate your infrastructure as quickly as possible. 

It is possible that your program requires more availability, in which case you may replicate it in different regions. This would ensure that your consumers are able to continue using your application in other regions even if one region becomes unavailable. The fact that you will also need to copy your resources is one of the challenges that you will face when replicating your application. You are not only required to keep a record of all the resources that your application needs, but you are also required to supply and configure those resources in each region. To ensure that your resources are created in a manner that is consistent and repeatable, you should reuse your CloudFormation template. Describe your resources only once, and then provision the same resources over and over again in a number of different regions. This will allow you to reuse your template.

Effortlessly manage and monitor infrastructure modifications 

There are situations in which you might have fundamental resources that you want to update in stages of gradual improvement. For instance, you might modify your Auto Scaling launch configuration to include a higher-performing instance type. This would allow you to limit the maximum number of instances that are allowed to be part of your Auto Scaling group. It is possible that you will need to restore your infrastructure to its initial configuration in the event that difficulties arise after you have finished installing the upgrade. In order to accomplish this manually, you not only need to remain aware of the resources that were altered, but you also need to be familiar with the settings that were initially in place.
Whenever you use CloudFormation to provision your infrastructure, the CloudFormation template will detail the specific resources that are provisioned as well as the settings for those specified resources. Considering that these templates are text files, all you need to do is monitor the differences between your templates in order to monitor the modifications that have been made to your infrastructure. This is analogous to the way that developers manage revisions to source code. As an illustration, you can make use of a version control system in conjunction with your templates in order to be aware of precisely what modifications were made, who made them, and when they were. You are able to use an earlier version of your template in the event that you find yourself in a situation where you need to undo changes made to your infrastructure.

AWS Deployment services

A key component of developing an architecturally sound application for AWS is planning how your application will be deployed. You can customise an AWS service-based deployment solution to meet the specific requirements of your application and business by considering its architecture and the foundational resources (compute, storage, database, etc.) it uses. The ever-expanding list of AWS services makes it harder to choose which services to use in your application’s architecture and even more difficult to decide how to build, operate, and upgrade your app. Take into account the following features when you create your AWS deployment solution: 

  • Supply: build the necessary infrastructure for your application, whether it’s raw resources (like Amazon Elastic Compute Cloud [EC2], subnets, etc.) or managed services (like Amazon S3, RDS, CloudFront, etc.). 
  • Configure: tailor your infrastructure to meet the needs of your application in terms of environment, runtime, security, availability, performance, and network. 
  • Installation or updating of your application’s component(s) onto infrastructural resources and management of the upgrade from an older version to a newer one are all part of the deployment process. 
  • Scale: You can change the number of resources your application has access to either in advance or in response to a set of user-defined conditions. 
  • Keep tabs on: showing you all the resources that your application’s architecture launches. Keep tabs on allocation of resources, application health, application logs, configuration drift, and the success or failure of deployments, among other things.

While planning a scalable, effective and affordable deployment strategy, it’s important to think about more than just installing new versions of your app. You also need to think about how you’ll manage the infrastructure that supports your app at all times. When you’re planning a deployment solution, it’s vital to think about a lot of different things, such managing configurations, deploying applications, updating software, monitoring, and creating access controls.
To help you maintain your applications throughout their lifecycle, AWS offers a variety of services. You can utilize these services individually or combine them to create a deployment solution with a lot of features; it all depends on the application and how you want to handle control vs convenience (like AWS resource management vs manual administration). Here we’ll take a look at the main features of the AWS services that can help businesses develop and release apps more quickly and consistently.

How is AWS CloudFormation effective

Using a custom template language defined in YAML or JSON, AWS CloudFormation allows users to supply and control nearly all AWS resources. The CloudFormation template groups infrastructure resources into a “stack,” and you may define and personalize all the components your application needs to run while keeping complete control over them. You can now apply version control to your infrastructure and reliably replicate it in a flash with the help of templates.

Everything from low-level components like route tables or subnet settings to high-level components like CloudFront distributions can be provisioned and managed with granularity using CloudFormation. When used in conjunction with other AWS deployment services or third-party tools, CloudFormation can handle the deployment of application code onto infrastructure components. This is achieved by combining CloudFormation with additional specialized deployment services.

Features for deploying AWS CloudFormation

  • The infrastructure components specified in a template can be automatically created and updated using Provision CloudFormation. 
  • Configure CloudFormation templates provide a great deal of leeway for personalizing and updating any part of the infrastructure.
  • Deploy: In order to modify the resources contained within a stack, you should update your CloudFormation templates. In order to upgrade the application version that is currently running on your infrastructure, it is possible that you will need to make use of an additional deployment service. This will depend on the architecture of your application. 
  • To scale: However, you are able to establish auto scaling policies for the resources you have as part of a CloudFormation template. CloudFormation will not autonomously handle scaling of your infrastructure on your behalf.
  • Observe: As well as “drift detection,” which monitors instances in what resources defined in a template do not meet criteria, CloudFormation offers native monitoring to track the success or failure of modifications to infrastructure that has been defined in a template. For the purpose of application-level monitoring and metrics, additional monitoring solutions will be required to be implemented.
