<p>These issues can be mitigated with <a href="https://www.hicloud.sg/news/blog/what-is-containerization">containerization</a>, which is also where <strong>Kubernetes</strong> comes in.</p>
<h2 id="kubernetes-a-container-orchestration-platform">Kubernetes: A Container Orchestration Platform</h2>
<p>Kubernetes is an open-source platform that automates container deployment, scaling, and management. It was originally developed by Google and is now maintained by the Cloud Native Computing Foundation (CNCF). </p>
<p>At its core, Kubernetes provides a way to <strong>manage and orchestrate containerized applications.</strong> Containers are lightweight, portable, and can be easily moved between different environments, making them an ideal way to package and deploy applications. Kubernetes allows containers to be deployed, scaled, and managed automatically, making it much easier for developers and operations teams to deploy and scale applications quickly and reliably. </p>
<p>In addition, Kubernetes is designed to be flexible and agnostic to the underlying infrastructure, which means it can run on any cloud provider or on-premises data center. Hence, the applications that Kubernetes manages can be deployed in almost any environment, despite its complexity and dynamism. </p>
<p>With its ability to simplify app deployment, Kubernetes is becoming the go-to platform for modern application development.</p>
<h2 id="key-concepts-in-kubernetes">Key Concepts in Kubernetes</h2>
<p>Kubernetes is based on a set of key concepts that provide the building blocks for deploying and managing containerized applications. Here are some of the main concepts:</p>
<ul>
<li><p>👉<strong>Pods:</strong> A pod is the smallest unit of deployment in Kubernetes. It represents a single instance of a running process in a container. Pods are used to group containers together and provide a shared network and storage space.</p>
</li>
<li><p>👉<strong>Services:</strong> A service is a way to expose a group of pods as a network service. It provides a stable IP address and DNS name that can be used to access the pods. Services can be used for load balancing, traffic routing, and service discovery.</p>
</li>
<li><p>👉<strong>Deployments:</strong> A deployment is a way to manage the lifecycle of a set of pods. It provides declarative updates for pods and replica sets, making it easy to roll out new versions of an application.</p>
</li>
<li><p>👉<strong>ConfigMaps:</strong> A ConfigMap is a way to store configuration data in Kubernetes. It can be used to store environment variables, configuration files, and other data that applications need to run.</p>
</li>
</ul>
<p>These concepts are designed to simplify app deployment and management by providing a declarative and automated way to manage containerized applications. By using these concepts, developers and operations teams can easily deploy and manage applications without having to worry about the underlying infrastructure.</p>
