Up to now, all resources were created manually using AWS Console or CLI tool.</p> <h2 id="cloudformation"> CloudFormation <a class="heading-link" href="#cloudformation"> <i class="fa-solid fa-link" aria-hidden="true" title="Link to heading"></i> <span class="sr-only">Link to heading</span> </a> </h2> <p>CloudFormation is the inhouse cloud provisioning tool of AWS for declaratively describing your cloud resources.</p> <p>CloudFormation is a hard, complex, inconsistent and badly documented piece of software. A stack is an atomic collection of resources in CloudFormation. Its creation or update succeeds only and only if all the resources within the stack succeed. A failure within a stack update leads to a rollback back to the previous state.</p>
