To shortlist VCF design blueprints, technical requirements are compared with this outline of what each blueprint delivers, which is grouped into expansion, recoverability, isolation, availability, physical site setup and consumption.

Each book explains Design profile in context, with comparison tables and the common traps.
Terms in this definition
- VMware Cloud Foundation
Broadcom's platform for private cloud. It unifies management of NSX, vSAN, vSphere, VCF Automation and VCF Operations as one fleet; VVF, by contrast, lacks automation and cloud management.
- Blueprints
Python v2 programming model objects (func.Blueprint) for splitting a function app's functions across several modules, which are then added to the main FunctionApp by calling app.register_functions().
- Agent identity blueprint
Template in Microsoft Entra Agent ID that holds credentials for one type of agent and obtains tokens for the agent identities created from it. Policies like Conditional Access set on it reach all those identities; Azure RBAC roles cannot be assigned to it.
- AMPRS
An acronym for availability, manageability, performance, recoverability and security: the five design qualities used to sort non-functional requirements and to weigh up trade-offs between design decisions.
- ACID
Four promises a database transaction makes: atomicity, consistency, isolation and durability. Azure Cosmos DB honours them, with snapshot isolation, only inside one logical partition, using stored procedures, triggers or transactional batch.
- Physical
Describes the concrete, real-world parts that put a logical architecture into effect.
- LSDOU
The sequence in which Group Policy is processed: the local policy first, followed by site, domain and organisational unit policies. The nearest, last-processed setting takes effect unless Enforced or Block Inheritance alters that.
- Consumption
Serverless, event-driven Azure Functions hosting plan charged per execution; runs are capped at 10 minutes and VNet integration isn't available.
Related terms
- Isolation
In the VCF Design Blueprints, the design profile category saying how workloads are separated from one another. Four kinds are listed (tenant-to-tenant, cluster-based physical, network traffic type and hypervisor-based logical), and the minimal-footprint blueprint supports only tenant-to-tenant and hypervisor-based isolation.
- Recoverability
One of the AMPRS design qualities, and a design profile category of the Design Blueprints: getting service and data back after a disaster, outage or data loss, judged by RTO and RPO. Availability is separate; it covers riding through failures the design expected.
