In what cases can Kubernetes be used?

Kubernetes is suitable for:

• Microservices architecture: Managing a large number of small, independent services becomes easier.
• Application scaling: Automatic load distribution and horizontal scaling of containers.
• CI/CD: Integration with continuous integration and delivery pipelines for automatic deployment and updates.
• State management: Working with StatefulSets for applications that need to retain data.
• Multitenant environments: Isolating workloads of different teams or clients within a single cluster.
• Ensuring fault tolerance: Automatic restart of containers and load redistribution in case of failures.
• Efficient resource utilization: Optimizing placement of containers on cluster nodes.

Use cases:

• Deployment of web applications and APIs.
• Management of background tasks and queues.
• Processing streaming data.
• Hosting Big Data platforms.

Not suitable for:

• Simple monolithic applications that do not require scaling.
• Small projects with limited resources (may be excessive).
• Tasks requiring full control over hardware.
