Stay in the IT game long enough and you’ll see the cyclic nature that exists as well as the patterns that form as tech trends go from hype to in-production. I remember working with virtualization technologies when you had to do things via the command line interface (CLI), such as configuring to your ESX host servers to connect with your fibre channel SAN. It was tedious and prone to human errors, so vendors simplified the experience with slick GUIs and one-touch clicks. Well, things have come full circle as the CLI is all the rage to gain scale and run lean via automation and orchestration scripts. With that in mind, here are a few things that virtualization admins need to remember.

 

First, let’s start with pattern recognition as in IT silos will always be targeted for destruction, even virtual ones. Just as virtualization broke down IT silos across networking, storage, application and systems, new technology constructs are doing the same to virtual silos. In this case, the virtualization silos are embodied by vendor-locked in solutions and technologies. Don’t be that IT guy who gets defensive about virtualization without seeking to understand the pros and cons of cloud services and container technologies.

 

Second, virtualization is an enabler of the application in terms of availability and data center mobility. Well guess what - containers, clouds, and microservices enable high availability and mobility beyond your on-premises data center at web-scale. So enable high availability and mobility in your career by learning and using these tech constructs.

 

Finally, let’s bring this conversation full circle – lean on your expertise and experience. If you know virtualization, you understand the underlying physical subsystems and their abstracted relationships to the application. Put that trust in yourself and embrace the new era of continuous service delivery and continuous service integration. It’s just an abstraction using a different model.
