Kubernetes
Kubernetes is a system for managing containerized applications – automated, scalable, and fault-tolerant.
For developers: a black box where services run.
For operators: an operating system for the cloud.
For companies: the platform behind many modern software products.
And for us: the standard for dynamic, production-grade systems.
What does Kubernetes do?
Kubernetes (also known as “K8s”) ensures applications run reliably – no matter which server or cluster they’re deployed on.
It takes care of tasks such as:
- Distributing containers across multiple compute nodes
- Restarting services if they fail
- Scaling depending on load
- Performing rolling updates with zero downtime
- Managing networks, secrets, and volumes
Kubernetes isn’t “a server” – it’s a system that organizes services.
Why is Kubernetes important?
Because modern software doesn’t run “on a server” anymore – it runs as a distributed system:
- Microservices, APIs, background workers, databases
- Running in containers, dynamic, often short-lived
- With changing demands and workloads
Kubernetes makes this complexity manageable, automated, and reliable.
Key Kubernetes concepts
- Pod: the smallest deployable unit (one or more containers)
- Service: an internal or external access point
- Ingress: controls external access (typically via HTTP/S)
- Deployment: defines how many pods of which version should be running
- Namespace: logical separation of Kubernetes objects (Pods, Ingress, Services) within a cluster
- ConfigMap / Secret: configuration and sensitive operational data (like database passwords or certificates)
How we use Kubernetes at RiKuWe
We operate Kubernetes clusters for teams, agencies, and businesses – flexible, secure, and transparent:
- Dedicated clusters (on-premise or in the cloud)
- Managed clusters for projects of any size
- CI/CD, GitOps, and observability built in
- Access via UI, CLI, or API – depending on your team
Kubernetes is powerful – and for us, it’s a tool, not a buzzword.
Frequently Asked Questions
What exactly is Kubernetes?
Kubernetes is an open-source system for managing containerized applications. It automates deployment, scaling, load balancing, and self-healing across many servers.
Why should I use Kubernetes?
If your app consists of multiple services, needs dynamic scaling, or runs in multiple environments, Kubernetes brings stability, automation, and clarity.
Is Kubernetes only for large companies?
Not at all. Smaller teams benefit too – from faster deployments, better error handling, and clean separation of environments. We offer clusters in any size.
What skills do I need for Kubernetes?
Basics in containerization (e.g. Docker), networking, CI/CD, and YAML are helpful. We handle operations – your team doesn’t need deep Kubernetes expertise.
What’s the difference between Kubernetes and Docker?
Docker is a tool to build and run individual containers. Kubernetes orchestrates many containers across multiple servers – including scaling, failover, and management.
