Now in 2015, can you tell me all the current VMware products and how they are related?
To look at VMware's product offering, it is best to look at VMware's vision on data center - Software Defined Data Center architecture.
Data Center comprises of these functions:
- Compute
- Storage
- Network
- Management
VMware’s
idea is to provide an abstraction layer for compute, storage and network
hardware so that the entire data center is software driven.
The advantage of a Software Defined Data Center architecture is that the data center can be more agile as the hardware resources are provisioned or withdraw on demand to the compute, storage and network resources. This agility factor has huge implication to IT operations in a data center:

- More cost effective
- Ability to service user demand much faster
- Provide a stable platform for DevOps
- Eliminate or minimize human error
- Make Disaster Recovery easier thus able to improve RTO and RPO.
The
benefits of a Software Defined Data Center architecture is not limited to the above
mentioned points and it is not the main point for this article.
VMware vCloud Suite is VMware's solution to provide a "Software Defined Data Center" for customers. As shown in the diagram below vCloud Suite comprises of:
Compute
At the heart of the vCloud Suite is the vSphere Suite that provide the virtualization infrastructure for different business establishments from SMB to enterprise to cloud operators. I don't think I need to describe much about the vSphere Suite as this has been around for a number of years and are widely deployed.
Management and Automation
The VMware vRealize™ Suite provides the management and automation capability for the Software Defined Data Center architecture.VMware vCloud Suite is VMware's solution to provide a "Software Defined Data Center" for customers. As shown in the diagram below vCloud Suite comprises of:
- Compute
- Storage and Availability
- Management and Automation
- Network and Security (add on feature)

Management and Automation
Basically, the vRealize Suite comprise of Automation, Operations and Business and Log Insight for monitoring.

Note:
- vRealize Operations is formerly known as vCenter Operations Management Suite or vCops
- vRealize Automation is formerly known as vCloud Automation Center or vCAC
- vRealize Business is formerly known as IT Business Management Suite
- vRealize Log Insight is formerly know as vCenter Log Insight
VMware vRealize Suite consists of the following products:
- VMware vRealize™ Automation™ Advanced or Enterprise
- VMware vRealize™ Operations™ Advanced or Enterprise
- VMware vRealize™ Log Insight™
- VMware vRealize™ Business™ Standard
- VMware vRealize™ Business™ Advanced or Enterprise
For all IT operations, disaster recovery is an important element. Each business should defined the Recovery Time objective (RTO) and Recovery Point Objective (RPO) for acceptable level of disruption in case of a disaster event affecting the continuous operation of the IT infrastructure. Most importantly DR plans needs to be tested. VMware vCenter Site Recovery Manager provide customer the ability to automate and orchestrate non-disruptive testing of recovery plans. With automation and orchestration, the RTO and RPO can be improved.

I am not sure why VMware group storage and availability into the same category because availability also include the compute and networking pieces that support the application that we are ultimately concern with.
Regarding storage, VMware had been working on abstracting the storage hardware and to provide an easy to configured Software defined Storage products. In this area, VMware is taking 2 approaches:
- Virtual Data Plane - Virtual SAN (VSAN) and vSphere Virtual Volume (vVol)
- Policy Driven Control Plane - Storage Policy Based Management
Network and Security
This is an add-on to to the vCloud Suite. In this category is the NSX - VMware's way of providing an abstraction layer to the physical network as well as some L4 - L7 network services.
NSX is also a security product as I have talked about in my previous post.
Brad Hedlund (@bradhedlund, Engineering Architect at VMware's Network and Security Business Unit) has an good article on what network virtualization is

NSX virtualized the network as well as network functions such as load balancing, firewall and VPN. Any Cloud management platform including OpenStack can interact with NSX via RESTful API to provision network services for the cloud platform.
NSX has two flavors as I have outlined in this post. One flavor is tailor toward vSphere product and the other one is for non VMware hypervisors such as KVM.
One point worth mentioning is that NSX can optimize the VXLAN multicast traffic because the NSX Controller is able to distribute the MAC address and VXLAN ID mapping to the various VTEPs instead of using bi-directional PIM as defined in RFC 7348 (I have a summary of this RFC here). Multicast traffics takes up network bandwidths and network administrators always try to find ways to eliminate multicast traffic.
Other VMware products
For a complete list of VMware products we can find them here. In this post I have not talked about the End-user computing product of VMware - Horizon nor the VMware hybrid cloud product - VMware Air which is the VMware's offering of public cloud similar to Amazon's AWS, Google's Cloud platform or Microsoft's Azure.
I hope this will clarify VMware's product offerings and how they relate to each other.
