Orkestrasi kontainer mengotomatisasi deployment, scaling, networking, dan manajemen kontainer di banyak mesin. Seiring aplikasi berkembang dengan banyak kontainer di berbagai host, manajemen manual menjadi tidak praktis — orkestrator seperti Kubernetes menanganinya. Memahami kebutuhan ini penting untuk scaling aplikasi berkontainer.
Masalah: mengelola kontainer dalam skala besar
Running a few containers on one host is manageable. But in production at scale:
→ MANY containers across MANY hosts (dozens/hundreds of services and instances)
→ containers crash → need to restart automatically
→ load increases → need to scale up (more instances) / scale down
→ deployments → roll out new versions without downtime; roll back on failure
→ distribute containers across hosts; route traffic; service discovery
→ Doing all this MANUALLY is impractical and error-prone. → ORCHESTRATION automates it.
