What is the Tech Radar?
The Tarmac DevOps Tech Radar is a list of technologies, complemented by an assessment result, called ring assignment. We use four rings with the following semantics:
- ADOPT — Technologies we have high confidence in to serve our
purpose, also in large scale. Technologies with a usage culture in our Tarmac production environments, low
risk and recommended to be widely used.
- TRIAL — Technologies that we have seen work with success in
project work to solve a real problem; first serious usage experience that confirm benefits and can uncover
limitations. TRIAL technologies are slightly more risky; some engineers in our organization walked this
path and will share knowledge and experiences.
- ASSESS — Technologies that are promising and have clear potential
value-add for us; technologies worth to invest some research and prototyping efforts in to see if it has
impact. ASSESS technologies have higher risks; they are often brand new and highly unproven in our
organisation. You will find some engineers that have knowledge in the technology and promote it, you may
even find teams that have started a prototyping effort.
- HOLD — Technologies not recommended to be used for new projects.
Technologies that we think are not (yet) worth to (further) invest in. HOLD technologies should not be
used for new projects, but usually can be continued for existing projects.
What is the purpose?
The Tech Radar is a tool to inspire and support DevOps engineering teams at Tarmac to pick the best
technologies for new projects; it provides a platform to share knowledge and experience in technologies, to
reflect on technology decisions and continuously evolve our technology landscape. Based on the pioneering work of ThoughtWorks, our Tech
Radar sets out the changes in technologies that are interesting in DevOps — changes that we think our
engineering teams should pay attention to and consider using in their projects.
How do we maintain it?
The Tech Radar is maintained by the DevOps team. Assignment of technologies to rings is the outcome of ring
change proposals, which are discussed and voted on in regular meetings. The Tech Radar depends on active
participation and input from all engineering teams at Tarmac.
BTW, if you would like to create your own Tech Radar — we use open source the code to generate this
