IaC, with its declarative approach, ensures that the desired state is clearly defined, and the automation tools handle the implementation, reducing the chance of discrepancies.<\/p>\n\n\n\n<p>Moreover, because the IaC solution is code that uses configuration files, it can follow the traditional version control process.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Code_Tools_vs_Manual_Configuration\"><\/span><strong>Code Tools vs. Manual Configuration<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>IaC tools like Terraform or Ansible streamline infrastructure provisioning through code. This contrasts with the traditional manual approach, where each configuration change required time-consuming manual intervention. Code tools enable faster, more reliable, and repeatable deployments. Code tools use config files that serves as the single source of truth for deploying infrastructure.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Imperative_vs_Declarative_Approach\"><\/span><strong>Imperative vs Declarative Approach<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>In Infrastructure as Code (IaC), the imperative and declarative approaches represent two distinct paradigms for defining and managing infrastructure configurations. Let&#8217;s explore each approach with examples:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"1_Imperative_Approach\"><\/span><strong>1. Imperative Approach<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The imperative approach is characterized by specifying the step-by-step instructions for achieving a desired state. In this method, the focus is on describing the sequence of actions that need to be taken to configure the infrastructure.<\/p>\n\n\n\n<p><strong>Example (using AWS CLI for provisioning an EC2 instance):<\/strong><\/p>\n\n\n\n<div class=\"wp-block-kevinbatdorf-code-block-pro\" data-code-block-pro-font-family=\"Code-Pro-JetBrains-Mono\" style=\"font-size:.875rem;font-family:Code-Pro-JetBrains-Mono,ui-monospace,SFMono-Regular,Menlo,Monaco,Consolas,monospace;line-height:1.25rem;--cbp-tab-width:2;tab-size:var(--cbp-tab-width, 2)\"><span style=\"display:block;padding:16px 0 0 16px;margin-bottom:-1px;width:100%;text-align:left;background-color:#22272e\"><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"54\" height=\"14\" viewBox=\"0 0 54 14\"><g fill=\"none\" fill-rule=\"evenodd\" transform=\"translate(1 1)\"><circle cx=\"6\" cy=\"6\" r=\"6\" fill=\"#FF5F56\" stroke=\"#E0443E\" stroke-width=\".5\"><\/circle><circle cx=\"26\" cy=\"6\" r=\"6\" fill=\"#FFBD2E\" stroke=\"#DEA123\" stroke-width=\".5\"><\/circle><circle cx=\"46\" cy=\"6\" r=\"6\" fill=\"#27C93F\" stroke=\"#1AAB29\" stroke-width=\".5\"><\/circle><\/g><\/svg><\/span><span role=\"button\" tabindex=\"0\" data-code=\"# Imperative approach using AWS CLI\naws ec2 create-key-pair --key-name MyKeyPair --query 'KeyMaterial' --output text &gt; MyKeyPair.pem\naws ec2 run-instances --image-id ami-0c55b159cbfafe1f0 --instance-type t2.micro --key-name MyKeyPair\" style=\"color:#adbac7;display:none\" aria-label=\"Copy\" class=\"code-block-pro-copy-button\"><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" style=\"width:24px;height:24px\" fill=\"none\" viewBox=\"0 0 24 24\" stroke=\"currentColor\" stroke-width=\"2\"><path class=\"with-check\" stroke-linecap=\"round\" stroke-linejoin=\"round\" d=\"M9 5H7a2 2 0 00-2 2v12a2 2 0 002 2h10a2 2 0 002-2V7a2 2 0 00-2-2h-2M9 5a2 2 0 002 2h2a2 2 0 002-2M9 5a2 2 0 012-2h2a2 2 0 012 2m-6 9l2 2 4-4\"><\/path><path class=\"without-check\" stroke-linecap=\"round\" stroke-linejoin=\"round\" d=\"M9 5H7a2 2 0 00-2 2v12a2 2 0 002 2h10a2 2 0 002-2V7a2 2 0 00-2-2h-2M9 5a2 2 0 002 2h2a2 2 0 002-2M9 5a2 2 0 012-2h2a2 2 0 012 2\"><\/path><\/svg><\/span><pre class=\"shiki github-dark-dimmed\" style=\"background-color: #22272e\" tabindex=\"0\"><code><span class=\"line\"><span style=\"color: #768390\"># Imperative approach using AWS CLI<\/span><\/span>\n<span class=\"line\"><span style=\"color: #F69D50\">aws<\/span><span style=\"color: #ADBAC7\"> <\/span><span style=\"color: #96D0FF\">ec2<\/span><span style=\"color: #ADBAC7\"> <\/span><span style=\"color: #96D0FF\">create-key-pair<\/span><span style=\"color: #ADBAC7\"> <\/span><span style=\"color: #6CB6FF\">--key-name<\/span><span style=\"color: #ADBAC7\"> <\/span><span style=\"color: #96D0FF\">MyKeyPair<\/span><span style=\"color: #ADBAC7\"> <\/span><span style=\"color: #6CB6FF\">--query<\/span><span style=\"color: #ADBAC7\"> <\/span><span style=\"color: #96D0FF\">&#39;KeyMaterial&#39;<\/span><span style=\"color: #ADBAC7\"> <\/span><span style=\"color: #6CB6FF\">--output<\/span><span style=\"color: #ADBAC7\"> <\/span><span style=\"color: #96D0FF\">text<\/span><span style=\"color: #ADBAC7\"> <\/span><span style=\"color: #F47067\">&gt;<\/span><span style=\"color: #ADBAC7\"> <\/span><span style=\"color: #96D0FF\">MyKeyPair.pem<\/span><\/span>\n<span class=\"line\"><span style=\"color: #F69D50\">aws<\/span><span style=\"color: #ADBAC7\"> <\/span><span style=\"color: #96D0FF\">ec2<\/span><span style=\"color: #ADBAC7\"> <\/span><span style=\"color: #96D0FF\">run-instances<\/span><span style=\"color: #ADBAC7\"> <\/span><span style=\"color: #6CB6FF\">--image-id<\/span><span style=\"color: #ADBAC7\"> <\/span><span style=\"color: #96D0FF\">ami-0c55b159cbfafe1f0<\/span><span style=\"color: #ADBAC7\"> <\/span><span style=\"color: #6CB6FF\">--instance-type<\/span><span style=\"color: #ADBAC7\"> <\/span><span style=\"color: #96D0FF\">t2.micro<\/span><span style=\"color: #ADBAC7\"> <\/span><span style=\"color: #6CB6FF\">--key-name<\/span><span style=\"color: #ADBAC7\"> <\/span><span style=\"color: #96D0FF\">MyKeyPair<\/span><\/span><\/code><\/pre><\/div>\n\n\n\n<p>In the above example, the commands outline the specific steps to create an EC2 key pair and launch an instance.
