As the pace of technology accelerates and the demands on IT organizations rapidly increase, enterprises are faced with a tension between two opposing forces:
- Maintaining a stable, high-performance, highly available, secure and scalable computing environment.
- Becoming more agile to be able to deploy new, uncertain projects and technologies more quickly.
And, of course, enterprises can’t abandon the critical components of the first demand to meet those of the second demand. In 2014, Gartner coined the term “Bimodal IT” to refer to a model for handling those two competing demands. Here’s Gartner’s IT Glossary (http://www.gartner.com/ it-glossary/bimodal) definition:
Bimodal is the practice of managing two separate but coherent styles of work: one focused on predictability; the other on exploration. Mode 1 is optimized for areas that are more predictable and well-understood. It focuses on exploiting what is known, while renovating the legacy environment into a state that is fit for a digital world. Mode 2 is exploratory, experimenting to solve new problems and optimized for areas of uncertainty.
My first ebook in this Geek Guide series, An Architect’s Guide: Linux for Enterprise IT, focused on Mode 1. I considered the major factors driving adoption of Linux in the traditional enterprise. I also looked at stability, performance, scalability, high availability, security, Windows integration, ease of deployment, management and upgrades, and support. And, I made the case that SUSE Linux Enterprise Server was a natural choice in high-performance computing environments for meeting those needs.
