VCDX Design selection

Operation Grandslam is now under way. I’m forcing myself to do this instead of putting it off while I try and get the VCAPs done and dusted. We’ve all been there when life at work and home consume vast amounts of time and effort as well as will power but the line in the sand has been drawn and I’ve stepped over it.

In the following weeks and months I will be doing an open design submission unless told I can’t due to NDAs or VCDX rules but at the very least I will be tracking my progress, airing my thoughts and agonising over decisions or processes. THe aim of this is so that you can perhaps get ideas or with any luck give some feedback and or support. It’s not going to be easy, if it were then everyone would be doing it wouldn’t they?

So this is just a quick post and in the next post I will be looking at the blueprint to see which of these design scenarios I will be going for in order to meet the blueprint requirements.

So these are the three I scenarios I’m considering for the VCDX design.

1. IAAS platform (non cloud)

A director of a managed services company wants to transform an existing co-lo data center and start offering Infrastructure As A Service to the current customer base as well as prospective new clients. This solution will need to take advantage of the very low network latencies between two data centers connected by Cisco Nexus switching and dark fibre services. This will be greenfield deployment in terms of VMware estate. More details to follow

2. Online banking platform

An existing customer has requested consultancy for deploying a new online banking platform service in order to keep up with technology and other services being offered by larger UK and Global banks. The new infrastructure must utilise the providers data centers, BGP networks/MPLS and meet explicit RTO and RPOs of services and data though PCI compliance is not required due to the nature of application delivery.

3. Acquisition and migration

An umbrella company has a business model of acquisitions and expansion and as such as taken over an insurance company to further increase their service portfolio and catalog. There are tight deadlines to absorb and migrate the new companies infrastructure from the existing sites due to termination of co-lo and managed services contracts. The online presence and services must not be impacted where possible with very small windows of downtime available. In addition to there are numerous Windows 2003 servers which will be out of support in the very near future as well as ageing infrastructure coming to end of life and service. There are additional requirements and constraints to follow…..


So those are the three that I’ve had to face in real life which I can draw upon in terms of experience but I will need to be tactical in which to pursue as too complex will increase the attack surface in my design defence or too little that I may not be able to score enough points on. I will be adding fictional requirements in all of these and detailing the Functional, non-functional requirements as well as the constraints, risks and of course the assumptions.

Oh and here’s the kicker…..I WILL be using hyper converged technology and will most likely be Nutanix. The reason for this was that I’ve experience with Nutanix and their products but more to do with the fact I truly believe in Hyper Convergence concepts and have seen first hand what it can do for a company and wished I had it for some of the engagements I’ve previously had to do. Just to be clear though, I’m not employed by Nutanix and if I had exposure to VMware EVO Rail or Pernix data then I’d be seriously considering these too IF and big IF in all cases it meets the REQUIREMENTS.

Until next time. Take care and have fun
