I was asked give a talk at a microservices seminar. My job was to cover/demo the tools used for 'typical' microservices deployments. ('Typical' is a generic term and does not lend itself well to this kind of talk, but whatever.) The tool-specific section of that talk is less important than the overarching themes I explored when I introduced the tools. Specifically, I outlined a hierarchy of dependencies that will enable (or derail) any microservices initiative.* They are, in descending order of criticality:
No strategic microservices initiative will succeed without a culture shift. No amount of brilliant developers and their concomitant skills can overcome a weak or antagonistic strategy. And the best tools cannot help you if you don't have the requisite skills.
If you are considering a microservices strategy and aren't sure what tools to use then it is very likely that you have other, more serious challenges. Is your culture in alignment with microservices principles and best practices? Is your strategy in alignment with your culture? Does your team have the skills to execute your strategy? If so, what tools are they most comfortable with?
Of course there are a great many other issues to consider - that's why Amundsen, et. al. wrote a book. Go there for more information, or use the google. It will not take very long to find more information than you ever wanted to know. If that's not enough then I will unpack each of the component dependencies in a later post (get excited!), but if all you take from this is the four key elements then you are off to a good start.
Thanks for reading.
* None of this happens in a vacuum. I adapted the work of the authors of this book along with some interesting and useful strategic thinking from some other hobby interests of mine.
