The requirement to support a 10% yearly workload growth is a non-functional requirement related to scalability and capacity planning. In VMware design methodology, scalability is intrinsically linked to performance. The core objective is to ensure the platform can accommodate future workloads without degrading service levels, such as application response time or throughput. Therefore, designing for growth is a key aspect of the performance design quality, as it dictates the initial resource sizing and the strategy for future expansion to maintain acceptable performance characteristics as the load increases.

B. Availability: This quality concerns system uptime, fault tolerance, and resilience against component failures, not the capacity to handle workload growth.

C. Manageability: This quality focuses on the ease of operating the environment, such as patching, monitoring, or provisioning resources, rather than the system's capacity to handle more load.

D. Security: This quality relates to protecting the infrastructure and its data from unauthorized access and threats, which is independent of workload growth requirements.

1. VMware Cloud Foundation Design Guide (Version 4.2)

Chapter 2: Architectural Overview

Section: "Design Objectives". This official guide explicitly groups "Performance and Scalability" as a single

key design objective. This demonstrates that in the context of VCF

a scalability requirement (like planning for growth) is classified under the performance quality.

2. VMware vSphere 7.0 Performance Best Practices Guide

Section: "Performance Management". The guide's introduction and capacity planning principles emphasize that a fundamental aspect of performance is sizing the environment to handle both current and future workloads. This directly connects the requirement for growth to performance design.

3. VMware vCloud Architecture Toolkit (vCAT) 3.1

Document: "Architecting a VMware vCloud"

Section 2: "The vCloud Service Definition". This toolkit

which outlines foundational cloud design principles

discusses service-level requirements. It links performance SLAs directly to capacity and the ability to scale on demand

reinforcing that planning for growth is a performance-related design consideration.
