What is Kubernetes
Kubernetes is an open source cloud-native container orchestration platform for declarative deployment, scheduling, elastic expansion and contraction, and automated operation and maintenance of containerized applications. It implements service discovery, load balancing, rolling updates, rollback and self-healing through control loops and APIs, and supports stateful and stateless workloads.
Core functions and features
- Automatic scheduling and elastic scaling, supporting horizontal/vertical expansion
- Health check, self-healing and failover ensure high availability
- Network, storage, configuration and secret management
- Extensible ecosystem: Operator, CRD, CNI plug-ins, compatible with
kubectl, Helm, Prometheus, etc.
Applicable scenarios and target users
Suitable for DevOps, SRE, platform engineers and development teams who need to build cloud-native architectures, often used in microservices, CI/CD pipelines, hybrid/multi-cloud deployments and enterprise-level production environments.
Main advantages
Open source and cloud-agnostic, with a mature ecosystem, declarative management and automated operation and maintenance can significantly reduce operation and maintenance costs and improve application portability and stability. It is the core platform for building modern distributed systems.
