Orcastráil choimeádáin a dhéanann uathoibriú ar an mbreiseán, scálúchán, líonraithe, agus bainistiú na gcoimeádán ar fud go leor meaisíní. De réir mar a bhíonn fás ar fheidhmchláir go go leor coimeádán ar fud iomadh óstach, bíonn bainistiú láimhe dodhéanta — déanann orcastrálaitheoirí cosúil le Kubernetes é. Tá sé tábhachtach tuiscint a bheith agat ar an ngá atá ann maidir le feidhmchláir choimeádáin a scálú.
An fhadhb: coimeádáin a bhainistiú ar scála
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.
