Does your IT shop use a combination wrench?

More and more, IT shops seem inclined to consolidate and simplify their infrastructure to one platform. A mindset that all workloads can or should run on a single platform incorporated into ‘Software-defined this’ and ‘Software-defined that’.  It tantalizes the decision makers senses as vendors claim to reduce complexity and cost.

Technology has become Ford vs Chevy or John Deere vs Case International.  Whereas these four vendors each have some unique capabilities and offerings they are also leaders in innovation and reliability.  For IT shops, there is this perception that only Intel & VMware are viable infrastructure options to deploy every workload type.  Mission / Life critical workloads in healthcare, high-frequency financial transactions, HPC, Big Data, Analytics, emerging Cognitive & AI but also traditional ERP workloads that run entire businesses – SAP ECC, SAP HANA and Oracle EBS are probably the most common that I see as there are also some industry specific ones for Industrial and automotive companies – I’m thinking of Infor.

When a new project comes up, there is little thought given to the platform. either the business or maybe the ISV will state what and how many of server X should be ordered. The parts arrive, eventually getting deployed.  Little consideration is given to the total cost of ownership or the the impact to the business caused by the system complexity.

I’ve watched a client move their Oracle workloads to IBM POWER several years ago. This allowed them to reduce their software licensing and annual maintenance cost as well as to redeploy licensing to other projects – cost avoidance by not having to add net new licensing.  As it happens in business, people moved on, out and up. New people came in whose answer to everything was Intel + VMware.  Yes, a combination wrench.

If any of you have used a combination wrench,  you know there are a few times it is the proper tool. However, it can also strip or round over the head of a bolt or nut if too much pressure or torque is applied. Sometimes the proper tool is a SAE or Metric box wrench, possible a socket, even an impact wrench.  In this clients case, they have started to move their Oracle workloads from POWER to Intel.  Workloads currently running on standalone servers or at most using 2-node PowerHA clusters.  Moving these simple (little complexity) Oracle VM’s to 6-node VMware Oracle RAC clusters that have now grown to 8-nodes.  Because we all know that Oracle RAC scales really well (please tell me you picked up on the sarcasm).

I heard from the business earlier this year that they had to buy over $5M of net-new Oracle licensing for this new environment. Because of this unforeseen expense, they are moving other commercial products to open-source since we all know that open-source is “free” to offset the Oracle cost.

Oh, I forgot to mention.  That 8-node VMWare Oracle RAC cluster is crashing virtually every day.  I guess they are putting too much pressure on the combination wrench!
