The increasing rate of change in applications and its amplitude footprint are causing a lot of consternation within IT organizations. It’s no coincidence, either, since everything revolves around the application, which is innovation personified. It’s the revenue-generating, value-added differentiation, and it's potentially an industry game changer. Think Uber, Facebook, Netflix, Airbnb, Amazon, and Alibaba.
Accordingly, the rate and scale of change are products in the application lifecycle. For instance, applications deployed in a virtualization stack will live for months or years, while applications deployed in a cloud stack will live for hours or weeks. Applications deployed in containers or with microservices will live for microseconds or milliseconds.
From my Interop 2016 DART Framework presentation.
For IT professionals, it’s good to know where job security is. As such, I’ve been keeping monthly tabs of the number of jobs with the key words virtualization, cloud, or (containers AND microservices), on dice.com. In the past year, since June 2015, the number of jobs with the key word "virtualization" has remained flat with around 2600 job openings. In that same time frame, the number of cloud jobs has increased by over 30% to 8900 job openings, while the number of container/microservices jobs has more than doubled, reflecting almost 600 job openings.
These trends re-affirm the hybrid IT paradigm and the need to deal efficiently and effectively with change in their application ecosystem. Let me know what you think in the comment section below.
