As an Enterprise Architect, whether you are getting ready for the VCDX Design Scenario portion of your VCDX defence or improving your “on the fly” consulting skills in client meetings, it makes a lot of sense to have a standard set of “Go-To” logical design templates that you can rely upon when white boarding.
List of articles in my VCDX Deep-Dive series (more than 70 posts)
In my opinion, you should be able to draw a functional representation of the following technology silos:
- Cloud Management Platform
- Virtual Infrastructure Management
- IT Service Management
- Network – Traditional Core, Distribution, Aggregation, Access topology
- Network – Clos-type leaf and spine topology
- Network Virtualisation
- Storage – Fiber Channel
- Storage – FCoE
- Storage – NFS
- Storage – iSCSI
- Storage – Distributed Software-Defined Storage
- Virtual Machine
- Information Security
- Business Continuity/Disaster Recovery
- End User Computing
White boarding techniques:
- In each of those areas, you should be able to highlight the Management, Control and Data Planes, and the Failure Domains.
- Be constantly tying back to the business problems solved/business value added and the requirements, constraints and assumptions met. This also includes the design qualities you will meet, eg. RAMPS.
- Your diagrams should be very neat and tidy. There should not be any illegible scrawling.
- Keep the white board eraser handy to clean up any errors.
- Carry your own white board marker set complete with different colours to simplify complicated concepts.
- Before erasing any of your work, take a photo with your smart phone. A picture is worth a thousand words and should be added to any minutes of meeting.
- Initially, you will probably have to refer to your documented “Go-To” diagrams, but as you become more practiced, they will be ingrained in your memory.
Here are some examples of what I am talking about:
