 What is LEAN technology?


Technologies often require a large number of dependencies or significant infrastructure, thus, increasing the complexity and cost to install, operate, and maintain. Lean technologies minimize the requirements necessary to use them, reducing the total cost of ownership.


Many technology products begin with a single, focused objective. They do that one job and do it well. However, to meet customer demand, the product evolves into a swiss army knife. Lean technologies deliver specific, individual capabilities with the ability to add or activate additional features in a simple, non-disruptive manner.

Low Cost

There is no such thing as free technology. While it may not appear in your accounting ledger, acquiring new technology requires some amount of resources to assimilate into your IT ecosystem. Lean technologies are well documented, offering guides for installation and configuration as well as tutorials and examples.

 Kickstart Your Project

Did you know that LEANSTACKS can help your project get up and running faster?

When a new application project is started, too often teams spend hours or days working on the project structure, application development scripting, and development operations automation. In the rush to work on actual project features, the bootstrapping initiative often falls short. When the project transitions from a "beta" or "proof-of-concept" into a production application, the shortcomings of the initial bootstrapping become even more painful.

To help project teams start new applications faster and with a solid foundation, LEANSTACKS has several starter project repositories available on GitHub including React, Angular, Marionette, and Spring Boot. For more information, go to the  Stacks page.

 Applications and Architectures

At LEANSTACKS we believe that to teach, you must also "do".

Hypothesize, experiment, construct, test, optimize, and repeat. Like any successful scientific process, that is how strong and long-lived systems architectures are created. No shortcuts. Just grit and ingenuity. That is the LEANSTACKS philosophy.

See how modern technologies and techniques combine to create robust, scalable, and highly available application systems. Learn how to use the  Stacks in conjunction with leading-edge cloud DevOps techniques to simplify and streamline application development workflows so that you can focus on what matters most... features.

To illustrate this approach, a sample of LEANSTACKS applications and their high-level architectures is available on the  Applications page.
