Containerization not only makes your application more portable, but it also enables it to run on a wider variety of hardware and operating systems. For example, developers can easily port their application from a desktop computer to a virtual machine (VM) or from a Linux to a Windows operating system. These containers can run either on a virtualized infrastructure or on a bare metal server, either on-premise or in the public cloud.&nbsp;<\/p>\n\n\n\n<p>Containerization fixed the age old problem of

class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Containerization is the packaging of software code together with just the operating system (OS) libraries and dependencies required to run the code into a single lightweight executable called a container. It then creates a consistent environment for running the code across any infrastructure.<\/p>\n\n\n\n<p>When you containerize an application, you create a package that contains all of the files and dependencies required to run the application. You then can run the container on any system that has a compatible version of the docker engine installed. This includes systems like Amazon EC2, Google Compute Engine, Microsoft Azure, and IBM BlueMix.<\/p>\n\n\n\n<p>To optimize the performance of your application, you can containerize it using Docker. This makes the application run inside a virtual environment, which reduces its overhead and makes it more responsive. You can also use containers to isolate different parts of your application from each other, which can improve overall performance.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p>Related: <a href=\"https:\/\/reviewnprep.com\/blog\/containerization-in-devops-explained\/\" target=\"_blank\" rel=\"noreferrer noopener\">How containerization differs from Virtualization<\/a><\/p><cite>Blog<\/cite><\/blockquote>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_To_Containerize_An_Application_Using_Docker\"><\/span>How To Containerize An Application Using Docker?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The easiest way to containerize an application is to use docker. With docker, you simply create a Dockerfile and build an image from it. You can then deploy the image on any system that has a compatible version of docker installed.<\/p>\n\n\n\n<p>At a high level the steps involved are:&nbsp;<\/p>\n\n\n\n<ol class=\"wp-block-list\"><li>Install Docker<\/li><li>Create a file called Dockerfile<\/li><li>Build the image<\/li><li>Run the image<\/li><\/ol>\n\n\n\n<p>Users can pick up images from Docker Hub (the world&#8217;s largest public repository of image containers) and use them to create customized images and containers.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_To_Containerize_An_Application_Using_Kubernetes\"><\/span>How To Containerize An Application Using Kubernetes?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>If you want to containerize an application that uses a lot of stateless services, then you should consider using Kubernetes. With Kubernetes, you can create a cluster and deploy your containers into it. This way, the containers (or each containerized application) are isolated from each other and from the rest of the system.&nbsp;<\/p>\n\n\n\n<p>To run an application on a cluster, you need to package your app into a container, create a Docker image from the container, and then push the image to the Docker registry. Next, you need to decide which image should be installed onto Kubernetes nodes. Kubernetes manages containers using a mechanism called Pods.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Are_The_Container_Certifications_Available\"><\/span>What Are The Container Certifications Available?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>There are a number of different container developer certifications available. The major certifying authorities include Docker, CNCF and RedHat.
