How many Kubernetes clusters do you need

Administrators need to determind:

• The number of Kubernetes clusters to manage
• Node size
• Decide which workloads should run on which cluster
• Isolate apps for security and compliance measures

Factors:

• Compliance requirements: for example, to physically isolate data
• Primary purpose of the cluster: an internal developer platform or production?
• Workload constraints or requirements: certain workloads require specialized hardware (e.g. GPU) that's only available in certain regions
• Customer requirements: some applications need to also run on-prem instead of SaaS
• Size of the infrastructure or platform team able to support the clusters: can my team support 100s of clusters or do we need a more centralized solution?
• Scale of the workloads running on Kubernetes: is your organization a small startup serving a few customers or a large corporation needing 1000s of nodes?
