Why using Kubernetes is important in deploying cloud software

What is Kubernetes?

Kubernetes is a container orchestration platform that automates the deployment, scaling, and management of containerized applications. This tool is designed to solve the challenges of large-scale container deployment. The containers themselves are light and portable and easy to use. However, managing them on a large scale can be challenging. By providing a unified platform, Kubernetes automates many tasks related to container management and solves problems related to their scalability.

Why is Kubernetes important?

Kubernetes has become an essential tool in the cloud. This tool provides a consistent way to manage containers in different environments, from development to deployment. With Kubernetes, developers can focus on writing code and let the platform handle the deployment and management of containers. Kubernetes also offers several advantages, including:

• Scalability: Kubernetes allows you to easily increase or decrease the execution power of your applications. You can add or remove containers on demand, ensuring that your application can be responsive as traffic increases.
• Fault tolerance: Kubernetes provides built-in fault tolerance, ensuring that your application remains operational even if one or more containers fail.
• Flexibility: Kubernetes works with a variety of container runtimes, including Docker, containerd, and CRI-O. This feature gives you the flexibility to use whichever system works best for your needs.
• Portability: Kubernetes provides a consistent approach to managing containers in different environments, such as data centers and cloud services such as AWS, Google Cloud, and Microsoft Azure.

How does Kubernetes work?

Kubernetes creates a collection of nodes under a cluster. Each node runs one or more containers, and Kubernetes manages the deployment and scaling of those containers. When a new container is deployed to the cluster, Kubernetes creates a pod. A pod is the smallest deployment unit in Kubernetes and consists of one or more containers.

Kubernetes also offers other features, including:

• Service Discovery: Kubernetes provides a built-in mechanism that allows you to expose your containers to other containers in the cluster.
• Load Balancing: Kubernetes provides internal load balancing for services, ensuring that traffic is evenly distributed across all available containers.
• Rolling Updates: Kubernetes allows you to do non-disruptive deployments, which means you can update your application without downtime.

Kubernetes and container systems have revolutionized application deployment and distribution by providing a standardized and portable solution for preparing and running applications. This has enabled developers to write code once and deploy it on any platform, automate deployment and management, scale applications up and down on demand, benefit from high availability and ensure the availability of resources and adopt modern application architectures. These improvements have resulted in faster, more efficient and more reliable deployment and distribution.

To learn Kubernetes, you need to have a general understanding of container systems such as Docker. Kubernetes is designed to work with containers, so if you're familiar with containers, reading about Kubernetes will be invaluable.

To learn and study, you can use the official documentation on the Kubernetes website.
