What Is VMware Cloud Foundation (VCF)?
VMware Cloud Foundation (VCF) is a powerful solution that provides a complete set of software-defined data center components in a single, integrated virtualization stack.
It combines compute virtualization with vSphere, network virtualization with NSX, storage virtualization with vSAN, and cloud management with VMware Aria Suite (formerly vRealize Suite). This integrated approach simplifies the deployment and management of private and hybrid clouds, enabling organizations to achieve greater agility, efficiency, and scalability.
When we consider VMware Cloud Foundation, we see that Broadcom's acquisition of VMware has significantly reshaped the VMware landscape. There is a shift away from perpetual licenses towards a subscription-based model. This means that instead of purchasing licenses outright, organizations now subscribe to VMware and specific capabilities on an ongoing basis.
Broadcom has streamlined the VMware product portfolio and bundled certain components that were previously sold separately. This bundling strategy aims to simplify purchasing and deployment.

vCenter also offers advanced features like performance monitoring, capacity planning, and automation capabilities, streamlining operations and improving efficiency.
vSAN
vSAN provides software-defined storage capabilities within it. It pools resources from multiple servers to create a distributed, highly available storage cluster.
vSAN, as a core component of VCF, creates a hyperconverged infrastructure by pooling storage resources from multiple servers into a distributed storage cluster, eliminating the need for dedicated storage arrays.
vRealize
VMware Aria Suite (formerly vRealize Suite) delivers cloud management capabilities to VCF, enabling automation, orchestration, and self-service provisioning of IT.
It includes components like vRealize Automation, which automates the deployment and management of applications and infra, and vRealize Operations, which gives intelligent monitoring and performance optimization for the entire center.
SDDC Manager
SDDC Manager is a key component of it that simplifies the deployment and lifecycle management of the entire SDDC stack.
It automates the installation, configuration, and upgrade components, reducing complexity and ensuring consistency across the environment. The manager also provides centralized management and monitoring capabilities for the entire deployment.
Tanzu
VMware Tanzu is included for organizations embracing modern application development and containerization.
Tanzu provides a stage for building, running, and managing Kubernetes clusters, enabling organizations to easily deploy and scale containerized apps. This integration of Tanzu brings the benefits of containerization to the SDDC, fostering agility and innovation.
Subscription Offerings and Editions
VMware Cloud Foundation offers flexible subscription options and a range of editions to cater to diverse needs and deployment scenarios. These offerings have evolved significantly under Broadcom's ownership, with a stronger emphasis on subscription-based models and bundled components.
VCF Subscription Offerings
It is primarily offered through subscription licenses, aligning with the broader industry trend toward recurring revenue models.
This subscription model provides several advantages, including predictable costs. It allows organizations to budget for VCF on an ongoing basis and avoid large upfront capital expenditures.
It also offers flexibility and scalability, enabling organizations to adjust their subscriptions as needs change and scale their deployments up or down. Finally, subscription licenses typically include access to the latest software updates, security patches, and technical support.
Available VMware Cloud Foundation Editions
VMware offers different editions tailored to specific use cases and sizes. These editions typically include a combination of vSphere, vSAN, NSX, vRealize, and SDDC Manager, with specific features and functionalities variations.
Some of the common editions include the VCF Standard, which provides a foundational set of SDDC components suitable for smaller deployments and organizations looking to adopt a hybrid cloud approach.
VCF Advanced includes more advanced features and functionalities, such as enhanced network virtualization capabilities with NSX and advanced automation with vRealize. It's designed for larger systems and organizations with more demanding requirements.
VCF Enterprise Plus is the most comprehensive edition, offering full features and capabilities. It's ideal for large enterprises and organizations seeking to build a fully software-defined data center with advanced management and automation.
VMware Cloud Foundation Architecture
VMware Cloud Foundation is built upon a modular architecture that centers around the concept of Workload Domains. These domains act as logical containers for allocating and managing topics like computing and networking.
A typical deployment includes a Management Workload Domain, which hosts the core management components like SDDC Manager and vCenter Server, and one or more VI Workload Domains dedicated to running apps and workloads. This separation enhances security and simplifies managing.
Benefits of VMware Cloud Foundation
VMware Cloud Foundation offers compelling benefits for organizations seeking to modernize their data centers and embrace a hybrid cloud strategy.
Integrating core components into a single solution simplifies management, reducing complexity and operational overhead. This leads to faster time to value and allows IT teams to focus on strategic initiatives rather than day-to-day maintenance.
VCF provides a consistent operational model across private and public cloud environments, enabling seamless mobility and hybrid cloud. This flexibility allows organizations to optimize resource utilization and leverage the best of both worlds.
With its software-defined approach, VCF delivers enhanced scalability and agility. Resources can be easily provisioned and scaled on demand, enabling organizations to respond quickly to changing business requirements.
Workload Domain Sizing in VCF
Workload domains are a fundamental concept in VCF, allowing you to segment and manage effectively. Proper sizing of these domains is crucial for performance, availability, and cost optimization. VCF typically includes three types of domains:
Management Domain
The management domain is the heart of your VCF environment, housing essential components like SDDC Manager, vCenter Server, and NSX Manager.
It's critical to size this domain adequately to ensure smooth operation and support for other domains. Factors to consider include the number of hosts, CPU, and memory capacity required for managing components.
Virtual Infrastructure Workload Domain
This domain is dedicated to running your core applications and workloads. Sizing depends on factors like your machines' number and resource requirements, anticipated growth, and performance needs. To ensure optimal performance and avoid resource contention, you must consider computing, memory, storage, and network capacity.
Virtual Desktop Infrastructure (VDI) Workload Domain
