Overview
Kubernetes (K8s) has become the standard platform for container orchestration, providing a portable, extensible foundation for running containerized workloads.
Key Features
Declarative Configuration
Define application deployments, services, and configurations in YAML:
apiVersion: apps/v1
kind: Deployment
metadata:
name: nginx
spec:
replicas: 3
selector:
matchLabels:
app: nginx
template:
spec:
containers:
- name: nginx
image: nginx:1.21
Self-Healing
Automatically replaces failed containers, reschedules workloads, and manages rollouts.
Horizontal Scaling
Scale applications based on CPU, memory, or custom metrics.
Service Discovery
Built-in DNS and load balancing for service communication.
Best For
- Microservices architectures
- Organizations standardizing on containers
- Teams requiring portability across clouds
- Applications needing high availability
Limitations
- Significant operational complexity
- Steep learning curve
- Overhead for simple applications
- Security requires careful configuration
Our Take
Kubernetes is essential for organizations running containerized workloads at scale. The learning investment pays off in operational consistency and ecosystem access.
