I’m a bit late to the micro service party and am not read up
on many of the concepts of micro services so some of the points of the seminar
might well have gone over my head. With that said I don’t feel that the title
of the presentation was thoroughly reflected in the talk. The point seemed to be that
data should not be duplicated over service boundaries but replicating data
within service boundaries is ok to solve problems such as performance
optimizations, optimization of queries, resolving latency issues, and resolving
network issues. The data that should be duplicated over service boundaries are
state changes, identifiers for what the request relates to, and date time info.
The rest of the talk was a mash up of what monolithic and
micro services are, publish-subscribe for messaging, and a brief show case on
how NServiceBus can be used to resolve monitoring issues. Both
the positive and negative parts of monolithic applications and micro services
was discussed which I thing is great. There was a short
example of micro services that used Uber as an example. During the presentation the SOA Patterns book was recommended as a good read.
During the presentation there was a small problem with the
audio going out however this was quickly and professionally resolved. Overall I
think it was a decent seminar however I think it could have been more focused.
