I am an author, speaker, and loud-mouth on the design of enterprise software. I work for ThoughtWorks, a software delivery and consulting company. This site contains lots of my writing on software development, which primarily focuses on software design and agile methods. To find your way around this site, go to the intro guide.

Drawbacks of Serverless Architectures

Mon 18 Jul 2016 10:08 EDT

Mike slaps serverless architectures with the wet fish of reality, looking at the drawbacks of using this approach. While some of these are due to the current state of tooling, others are an inherent "feature" of this architecture, based on a high degree of dependence on specific vendor capabilities and limitations.

Benefits of Serverless Architectures

Wed 13 Jul 2016 09:35 EDT

Mike continues his examination of serverless architectures by wandering in the land of serverless unicorns and rainbows. Here the serverless style can reduce operational and development costs, drastically reduce scaling costs, ease operational management, and even save the planet from global warming.

Bliki: BoiledCarrot

Thu 23 Jun 2016 09:37 EDT

I hated carrots when I was growing up, hating the smell and texture of the things. But after I left home and started to cook for myself I started to like them. Nothing changed about the carrots, nor did my taste buds get a radical overhaul, the difference was in the cooking. My mother, like so many English people of her generation, wasn't a great cook - particularly of vegetables. Her approach was to boil carrots for twenty minutes or more. I since learned that if you cook them properly, carrots are a totally different experience.

This isn't a site about cooking, but about software development. But I find that often a technique or tool is like the poor carrot - blamed for being awful when the real problem is that the technique is being done incorrectly.

Bliki: BimodalIT

Tue 21 Jun 2016 10:07 EDT

Bimodal IT is the flawed notion that software systems should be divided into these two distinct categories for management and control.

  • Front Office systems should be optimized for rapid feature development. These systems of engagement need to react rapidly to changing customer needs and business opportunities. Defects should be tolerated as the necessary cost for this rapid development cycle.
  • Back Office systems should be optimized for reliability. As systems of record, it's important that you don't get defects that damage the enterprise. Consequently you slow down the rate of change.

Bliki: Serverless

Mon 20 Jun 2016 11:08 EDT

Serverless architectures are internet based systems where the application development does not use the usual server process. Instead they rely solely on a combination of third-party services, client-side logic, and service hosted remote procedure calls (FaaS).

Continuous Integration and Delivery

For a long time I’ve been a champion of Continuous Integration which reduces integration risk by integrating early and often, an application of the principle of Frequency Reduces Difficulty. We’ve found CI to be a core technique at ThoughtWorks and use it almost all the time. At the heart of this is a style of development that minimizes long feature branches with techniques like Branch By Abstraction and Feature Toggles.

While this is useful, there was still risk present from software that works in the development environment to getting it to work in production. As a result we developed Deployment Pipelines to reduce this risk, moving closer to our aim of Continuous Delivery: building software in such a way that we confidently deploy the latest builds into production whenever there is a business need. We find this improves feedback, reduces risk, and increases the visibility of project progress.

For more information: take a look at my guide page on Continuous Delivery.


NoSQL Databases

I’ve been involved in enterprise software for two decades and while we’ve seen huge technological change during that time, the relational database has been a constant figure. Previous attempts to dethrone relational databases have failed, but some people think the new rise of NoSQL databases will finally consign relational databases to history. While I think relational databases are going to be an important part of the landscape for a long time, I do think that there is a big change coming in the database field.

I’ve been collaborating with my colleague Pramod Sadalage, on exploring and explaining this shift. For more information take a look at the nosql guide.

I discovered ThoughtWorks in 2000: then a small American company whose philosphy of software development was remarkably similar to my own. Now we’ve grown to around 4000 people world-wide, but kept the values that make us special. My colleagues have built critical systems for many clients in that time, and I’ve learned many lessons from them. While doing this, we found we often didn’t have the tools we needed, so we started to build them. This led to open-source tools such as CruiseControl, Selenium, Frank, and Moco as well as commercial products.

I have many opportunities, but I’ve stayed at ThoughtWorks because of the quality of my colleagues, who include both well-known speakers and those who may not be famous names but do an excellent job of software delivery (and feed me the information to write about). We are inspired by working with each other and our unusual three-pillar philosophy that raises professional excellence and social justice to the same level as financial performance.

And we are always looking for more great people to join our curious company. Maybe I’ll see you in one of our offices some day.
