I have been steady, since the beginning of the “public cloud”, in saying that private cloud is HERE TO STAY. I’ve told multiple managers, executives at VMware and even in the Office of the CTO that while I agree that Private / Hybrid cloud is all the rage right now, the expansion of private cloud instances will continue and will accelerate in the coming years. i made the statement that “I will retire from this career while continuing to roll out designs & instances of Private Cloud”.
Time is undefeated, it always wins – and by that I mean that once we have hindsight, we are all very wise in that regard — and in this case, the early adopters have really gained huge insights from their public cloud efforts. Many of them have proven to be very fruitful, the scale, the dynamic nature of cloud “on demand”, the ability to have a single management plane which covers all your cloud instances, private, public, hybrid etc with one management plane is simply amazing control. Amazon AWS also provides amazing analytics, the “powered by AWS” branding has really taken off and people are looking for new insights from their data and their business.
But… There have been costs and they are not insignificant in some cases. There have been migration headaches, there have been lock-ins and failure to move workloads around with impunity. (as previously promised).
As a result, i would like to welcome people BACK TO THE PRIVATE CLOUD. This is, of course, great news for the hardware vendors, HP, Dell, Lenovo, Fujitsu, Hitachi, Oracle among many others will continue to sell very competitively priced racks of gear, much of it consolidated Storage, Compute and network in the same rack just like when we designed VCE vBlocks back in 2005 on a white board in the Atlanta EMC office ( Story for another day – yeah i did help with that).
The key in all of this as we MOVE BACK INTO PRIVATE, it to remember all of the lessons from the CLOUD-NATIVE world because THEY APPLY. (These are the updated Cloud Commandments)
- Security is job 1
- Build for interoperability
- Build Cloud Agnostic
- Automate all things (this means the management plane & standards are important)
- Use industry standards (for micro-services, for blueprints, for designs, etc)
- Abstract, Abstract, Abstract
- Get early answers to questions on: HA, DR, RPO/RTO
- Leverage Infrastructure as code
- Watch ingress/egress if leveraging hybrid or public
- If you can code to VMware Cloud Foundation as a standard, VCF, your life will be better.
