Kubernetes: What It Is and Why Your Business Needs It

Modern IT systems are becoming increasingly distributed and complex. Businesses use dozens of microservices, each requiring individual deployment, configuration, and scaling. Under such conditions, traditional server solutions quickly become inadequate. This is precisely where Kubernetes comes into play.

What Problems Does Kubernetes Solve?

The Kubernetes system enables automatic deployment, management, and scaling of containerized applications. Developed by Google, it has become the de facto standard in the world of DevOps and cloud infrastructure.

For companies actively working with web services, mobile applications, SaaS products, and digital platforms, Kubernetes addresses a comprehensive set of critical challenges:

• Accelerated application deployment—new versions go live in minutes, not hours.
• Automatic scaling—traffic increasing? Kubernetes will spin up additional containers on its own.
• Fault tolerance—a single node failure won't bring down the service.
• Resource efficiency—containers mean you only pay for the capacity you actually use.
• Development flexibility—seamless support for microservice architecture and CI/CD workflows.

Understanding Kubernetes Architecture

At the core of it all are Kubernetes containers, which package an application along with all its dependencies into a single executable unit. These containers run on virtual or physical servers and are completely isolated from one another.

A Node in Kubernetes is a server (physical or virtual) where containers are deployed. A single cluster can contain dozens or even hundreds of such nodes, all managed centrally. It is the Kubernetes Server that makes decisions about resource allocation, monitors container health, and handles all orchestration.

A Kubernetes Cluster unites numerous nodes into a single cohesive system. This allows thousands of containers to be managed as easily as a single machine. The cluster automatically redistributes workload, monitors application status, and resolves failures.

Kubernetes Services provide a mechanism for stable access to containers. Even if a container is restarted or moved to a different node, the service continues to route requests correctly. Without Services, communication between system components would be chaotic and unstable.

Kubernetes Networks enable communication between pods (groups of containers), services, and the outside world. Proper network configuration ensures security, traffic control, and stable operation of all microservices.

Many companies utilize Kubernetes with NGINX as a proxy server and load balancer. NGINX delivers high performance and security at the ingress traffic level.
