Fundamentals of Cloud Computing

2023-05-03T05:40:24+00:00

In the previous post, we discussed what cloud computing is all about. In this section, we'll talk about the fundamentals of cloud computing. Before you deep dive into the different cloud services, let's first take a look at the summary of the fundamentals of cloud computing. Cloud services are usually classified by their general use cases that make up an IT infrastructure. You can think of them as lego blocks. One piece of a lego block looks dull and doesn't really mean much. But once you've learned how to fit those blocks on top of each other in a creative [...]

What is Cloud Computing?

The first time you hear the term Cloud Computing, you probably have asked yourself these questions: “What exactly is the Cloud in Cloud Computing?” and “Why do so many companies use it?” Basically, cloud computing is an on-demand computing service that you can avail over the Internet to host and run your applications.

AWS CloudFormation Deletion Policy

2023-06-03T04:57:38+00:00

Deleting a stack on CloudFormation also removes all the provisioned resources in it. In some cases, you want some resources to be retained even after deleting its stack. The good thing is that you can do this by defining its DeletionPolicy.  This is pretty straightforward - you just need to define DeletionPolicy with Retain value and for the resources that support snapshot, (like RDS databases) you can set Snapshot as its value. With DeletionPolicy: Snapshot, a snapshot is created before a resource is deleted. This allows you to have a backup of the resource that's been deleted from the stack.  [...]

AWS CloudFormation StackSets and Nested Stacks

2023-06-03T04:59:37+00:00

AWS CloudFormation lets you model and provision resources for your environment using programming language, leveraging the concept of Infrastructure as Code (IaC). You don’t need to manually create all of your resources one by one, CloudFormation will do this for you. All resources are defined on the AWS CloudFormation template. This means that this AWS environment can be reliably and easily reproduced since everything is declared on a template. For example, creating a new Test environment similar to your current setup, or when creating a Disaster Recovery environment in another region.  With AWS CloudFormation, you can either upload your own [...]
