Bimodal IT??? An introduction to combining reliability and agility.

Early June 2014 Gartner introduced a new word to indicate a two-speed IT delivery: Bimodal IT.

I am sure Bimodal IT is a word you will hear a lot in the future!

Bimodel IT is an IT-model which has both the robust, traditional way of delivering IT plus the new, agile DevOps way of delivering IT.


These are basically two eco-systems  with different expectations, cultures, mindsets and tools. Traditional IT is called mode 1 by Garner, while agile, business focussed IT is called Mode 2.

Mode 2 has terms like SDDC, SDS, SDN, SDI, DevOps, Continious Delivery & Continuous Integration.


Business, consumers are used to speed, agile services. The only way for IT-departments to adopt to this demand and avoid shadow-IT is to adopt the agile way of delivering IT to their customers while maintaining the legacy, often business critical applications.

Bimodal IT is not some hype which will be gone in a couple of years. At a recent Gartner Datacenter Conference 68% of the attendees at a presentation answered they are or will implement Bimodal IT within 3 years.

An example of traditional organizations using Bimodal IT are banks. In mode 1 they operate all kind of specific, legacy, business critical applications. These often run on mainframes and are written in legacy code like Fortan. Changes in these applications take many weeks to complete.

Banks needs to compete and be cost-effective. Many public facing jobs are being replaced by web and mobile apps available for customers on internet. The applications require a must faster delivery than the mode 1 legacy applications.

The same applies for airlines or large retailers which are shifting from shops (bricks) to e-commerce (clicks).

To survive in a competing market they need both robust mode 1 IT-delivery as well as agile & fast delivery.

Hybrid cloud is an ideal model to operate Bimodal IT on.On-premises legacy applications combined with cloud native apps in a hybrid infrastructure combing the best of two worlds.
