<h1>Docker 101<a class="headerlink" href="#docker-101" title="Link to this heading"></a></h1>
<p>Docker is a platform for developing, shipping, and running applications. It uses containerization technology to package software and its dependencies into standardized units called containers. These containers are lightweight, portable, and isolated, allowing applications to run consistently across different environments, from development to production.</p>
<p>With Docker, developers can build, ship, and deploy applications faster and more efficiently by eliminating compatibility issues between different systems. Docker simplifies the process of managing and scaling applications, making it easier to deploy and update software in any environment, whether it’s on-premises, in the cloud, or hybrid.</p>
<p>Overall, Docker revolutionizes the way applications are developed, deployed, and managed, enabling teams to innovate more rapidly and reliably.</p>
<section id="motivation-for-containers">
<h2>Motivation for Containers<a class="headerlink" href="#motivation-for-containers" title="Link to this heading"></a></h2>
<p>To see why containers are useful, let us look at the following 2 scenarios.</p>

<h1>Evolution of Virtualization<a class="headerlink" href="#evolution-of-virtualization" title="Link to this heading"></a></h1>
<p>In modern computing, various technologies cater to different needs and scenarios. Bare metal, virtual machines, and containers represent three fundamental approaches to deploying and managing applications, each with its own set of advantages and use cases.</p>
<section id="bare-metal">
<h2>1. Bare Metal<a class="headerlink" href="#bare-metal" title="Link to this heading"></a></h2>
<p>Bare metal refers to the traditional method of running applications directly on physical servers without any virtualization layer. In this setup, the operating system interacts directly with the underlying hardware. Bare metal environments offer maximum performance and control since all resources are dedicated to the application. They are ideal for high-performance workloads where every bit of computational power counts.</p>

</section>
<section id="virtual-machines-vms">
<h2>2. Virtual Machines (VMs)<a class="headerlink" href="#virtual-machines-vms" title="Link to this heading"></a></h2>
<p>Virtual machines emulate physical hardware within a host server, allowing multiple operating systems and applications to run independently on the same physical hardware. Each VM runs its own guest operating system, providing strong isolation from other VMs. VMs offer flexibility, enabling different operating systems and configurations to coexist on the same hardware. They are commonly used for server consolidation, testing, and development environments.</p>
<p>When using VM, a hypervisor is usually needed. It is a software or firmware layer that enables the creation and management of virtual machines (VMs) on physical hardware. It sits between the hardware and the operating systems (OS) running on the VMs, facilitating the sharing of physical resources among multiple virtual environments.</p>
<p>There are two main types of hypervisors:</p>
<ol class="loweralpha simple">
<li><p>Type 1 Hypervisor (Bare Metal Hypervisor):</p></li>
</ol>
<p>Type 1 hypervisors run directly on the physical hardware without the need for a host operating system. They are often referred to as “bare metal” hypervisors because they have direct access to the underlying hardware.
Examples include AWS Nitro System, VMware vSphere, and Microsoft Hyper-V.
Type 1 hypervisors provide efficient and high-performance virtualization, making them suitable for enterprise-level deployments and cloud computing environments.</p>
<ol class="loweralpha simple" start="2">
<li><p>Type 2 Hypervisor (Hosted Hypervisor):</p></li>
</ol>
<p>Type 2 hypervisors run on top of a host operating system, which means they rely on the underlying OS for hardware access.
These hypervisors are commonly used on desktop or workstation environments for development, testing, and running multiple operating systems simultaneously.
Examples include Oracle VirtualBox, VMware Workstation, and Parallels Desktop.
While Type 2 hypervisors offer ease of use and flexibility, they may introduce some performance overhead due to the additional layer of the host OS.</p>

<h2>3. Containers<a class="headerlink" href="#containers" title="Link to this heading"></a></h2>
<p>Containers are lightweight, portable, and isolated environments for running applications and their dependencies. Unlike VMs, containers share the host operating system’s kernel, which reduces overhead and improves efficiency. Containers provide fast deployment times and scalability, making them ideal for microservices architectures, continuous integration and deployment (CI/CD) pipelines, and DevOps practices.</p>
