Introduction
Hello to all readers of the blog about IT Architecture and Training!
In the previous article of the “VMware Training and Certification. Year 2025” series, we examined VMware Aria Automation as the automation and orchestration layer of VMware’s cloud management platform.
In this article, we shift our focus to the Network Virtualization learning domain and explore VMware NSX – VMware’s software-defined networking and security platform that forms the foundation of modern virtualized and cloud-native network architectures.
The VMware NSX training direction includes educational programs designed to help IT professionals design, deploy, and operate virtualized networks and security services across vSphere, VMware Cloud Foundation, and multi-cloud environments. Key areas include overlay networking, logical switching and routing, microsegmentation, distributed firewalling, load balancing, VPN, and advanced security services.
This article provides an overview of the current VMware Authorized Training programs for VMware NSX, their structure, learning objectives, and their alignment with real-world enterprise network and security architectures.
VMware NSX

VMware NSX-T Data Center is the network virtualization and security platform that enables the virtual cloud network, a software-defined approach to networking that extends across data centers, clouds, and application frameworks.
VMware has updated the product name for the VMware NSX-T data center to VMware NSX. This change better reflects the capabilities and benefits the product brings to customers.
From an architectural perspective, VMware NSX implements a full-stack software-defined networking (SDN) and security model by virtualizing network functions in software and decoupling them from the underlying physical infrastructure.
At its core, NSX provides overlay networking using encapsulation technologies such as Geneve to create logical Layer 2 and Layer 3 networks that are independent of the physical topology. Logical switches and routers enable flexible network segmentation, dynamic routing, and workload mobility across clusters, data centers, and cloud environments.
A defining architectural component of NSX is its distributed firewall (DFW), which operates at the hypervisor or workload level, enabling microsegmentation with fine-grained, identity-aware security policies. This allows security controls to follow workloads wherever they move, enforcing zero-trust principles within the data center.
NSX also delivers network services virtualization, including load balancing, VPN, NAT, and advanced threat prevention. When integrated with VMware Cloud Foundation, NSX becomes the native networking and security layer of the SDDC, tightly coupled with vSphere, vSAN, and VMware Aria for unified operations, automation, and lifecycle management.
This architecture enables organizations to implement agile, secure, and scalable network infrastructures that support hybrid and multi-cloud strategies.
The main current training programs for VMware NSX technologies are:

Brief Summary
This article explored VMware NSX as the core platform for network virtualization and security within modern VMware-based infrastructures. We examined how software-defined networking, overlay architectures, and distributed security services enable flexible, scalable, and secure network designs across vSphere, VMware Cloud Foundation, and multi-cloud environments.
By introducing capabilities such as microsegmentation, distributed firewalling, and virtualized network services, VMware NSX establishes a security-first networking model where policies are tightly coupled to workloads rather than physical network boundaries. Integrated with VMware Cloud Foundation and VMware Aria, NSX becomes a foundational layer for secure, automated, and operationally consistent SDDC architectures.
In the next article of the “VMware Training and Certification. Year 2025” series, we will shift our focus to the End-User Computing (EUC) learning domain and explore VMware Horizon 8 — VMware’s platform for delivering virtual desktops and applications.
We will review the Horizon 8 training programs, their architectural components, and how EUC solutions integrate with vSphere, NSX, and VMware Cloud Foundation to deliver secure, scalable, and centrally managed digital workspaces.
Follow the news until the meeting is on air in a few days.
Sincerely, AIRRA.
