The Lean Architecture

January 21, 2010

This is the second in a series of articles on building elastic cloud applications. Read the first article here.

Adapting the Lean Startup principles to application architecture produces a few significant requirements. A Lean Architecture has the following properties:

  • requires next to none upfront cash investment
  • is flexible to changing application requirements
  • requires little time investment to scale
  • incurs moderate scaling costs

Taking these principles into account, it becomes obvious why some early design decisions may affect your business’ ability to cope with the challenges during the early stage and later growth.

While IaaS saves monetary investments in hardware and long-term hosting contracts, it also frees up valuable human resources used to set up and manage data center infrastructure. And when your user base finally grows, the elastic cloud absorbs the extra load without creating sleepless nights and requiring urgent visits to the data center.

Startups don’t fail because the technology doesn’t work. They fail because nobody wants what they are trying to build.

Eric Ries

Eric Ries and his blog ‘Lessons Learned’ offer insights on how to build a Lean Startup. A recent presentation from Eric Ries’ on Lean Startups in the Stanford University’s Entrepreneurship Corner explains his approach to building a technology product. In his pragmatic view on how to integrate Customer Development with Agile Software Development, he advocates an approach with two teams. The cross-functional problem team continuously validates the problem hypothesis and updates the product concept, while the solution team uses an Agile Software Development methodology to build the product from the product concept.
