I have spent some time working on various Cloud Technologies evaluating, designing, developing and demonstrating cloud solutions to customers and wanted share my experience though this medium.

As a consultant we spend most of our time in sizing and hence I was a keen to share my understanding on different sizing methodology. A lot of times working in SMB segment gave me this insightful experience that if you size it right, most of the times you might win the deal. This is one of the most critical job of a Solution Architect / Consultant


You Sales engineer need more money

The customer wants to spend less

You are the bridge between these two towers and you have to do a balancing act, your maturity in handling the customer and your sales co-ordinate is the key to you, your sales engineer, and your organization.


Less Sizing: To please the customer if you size it less and give a lower BOM you are literally messing up with your sales counterpart.

You size it less and you please the customer your sales counterpart would not be happy that you are messing up with the business, this is a very serious issue with the sales team. You are messing up with their bread and butter.

More Sizing: To please your sales engineer if you give a wrong sizing you are really messing up with your customer and hence with your sales counterpart.

You size more and you give a large number the customer, remember that customer is no fool and you give a large BOM customer might give your solution a miss because of the BOM, your sales is furious with you because you are not capable of convincing the customer the right BOM.


I have dedicated a blog for the same where I have tried to list some of the sizing tools which are commonly used.

Sizing Tools

I have tried to evaluate multiple sizing tools and I have published detailed information on the same for example

HP Sizer for Server Virtualization

 An easy to use sizing tools for virtualization if you have a mix of Hyper-V and VMware, the best part of the tools is the recommendations could be used for making purchasing decisions

Microsoft Hyper-V Sizing with MAP
VMware SAP Sizing

This is one of the most discussed and debated subjects if you are a virtualization consultant and if the customer is migrating SAP to virtualization. Customer is always convinced that SAP cannot run on virtualization and he needs a physical machine but as a virtualization consultant you have work double harder (hopefully less hard in the near future) to convince that customer for the same. I have learnt a lot from my VMware BSN (B.S Nagaragan) and this is his gift to me. He spent time with me so that I understood things properly.

Nutanix Sizer

Well Hyper Convergence is the new buzz words in 2015/16 and this tool comes in handy. Nutanix has made sure to give the right set of tools the partner/customer/consultants to make sure that they size is right and this tool is one of examples about how to hide complexity and give in simple user interface to the end-user.
