VCF 9.0 GA Mental Model Part 5: Topology Patterns for Single Site, Two Sites, and Multi-Region

TL;DR If you want architects, operators, and leadership aligned, you need a topology mental model that starts with VCF objects and only then maps to your physical sites. The hierarchy you should standardize on is Fleet -> Instance -> Domain -> Cluster. Your topology decision is mostly about: How many instances you deploy and how […]

VCF 9.0 GA Mental Model Part 3: Day-0 to Day-2 Ownership Across Fleets, Instances, and Domains

TL;DR If you want clean accountability in VCF 9.0, anchor your operating model to the official hierarchy: VCF private cloud -> VCF fleet -> VCF instance -> VCF domain -> vSphere clusters. This post translates that hierarchy into an operating model: who owns what, where day-0/day-1/day-2 work happens, and how topology (single site vs two

VCF 9.0 GA Mental Model Part 2: Fleet Services vs Instance Management Planes (and Who Owns What)

TL;DR Standardize on the official hierarchy: VCF private cloud -> VCF fleet -> VCF instance -> VCF domain -> vSphere clusters. A VCF fleet is managed by one set of fleet-level management components (notably VCF Operations and VCF Automation), while each VCF instance keeps its own management domain and domain-level control planes. Your fastest path

VCF 9.0 GA Mental Model Part 1: Fleets, Instances, Domains, and the Fleet Management Layer

TL;DR If you want alignment fast, standardize on this hierarchy and ownership split: Organizational private cloud (program term) -> VCF Fleet -> VCF Instance -> VCF Domains (management and workload) -> vSphere clusters A fleet is the boundary for shared fleet services (operations, automation, identity, governance). It is not “one shared SDDC management plane.” An
