The Tao of Microservices : Convert legacy modules to microservice(s)

[Vijitha Kumara]

Hi,

What's your thoughts on making old legacy systems as microservices? Do you discuss about the approaches/best practices in the book?

I see some references to monolithic systems under Services chapter but do you discuss in detail about the process?

Hi Vijitha - I cover this topic in the book. It is not only technical but also requires navigation of organizational politics.

The solution is to break the old system systems
into “macroservices” where possible so that you can leverage the rapid deployment system that microservices give you.

When this is not possible, you wrap the old systems using proxy services, so that they are abstracted by message flows.
