Re: What are micro-services?

I heard the folks from the NYTimes at a GOPHER meeting (that's the Go
language people, Go is being used extensively for microservice programming).

Every section of the NYT used to have its own web team and they did things
each there own way.

NYT centralized and services like "get ad" become microservices so web
programming by the vertical teams was largely reduced to handing content to
layout verbs with the return becoming the argument to composition verbs.

It's factoring. All us old FORTH programmers are factoring geeks.
Microservices is factoring your enterprise server offering into small,
coherent, "does one thing well" verbs to be woven into applications by the
web programmers.

I see them exactly as Google suggest.. small little applications that do
certain things (figure tax, shipping, exchange rates, etc). Not the best
examples, but all I could think of off hand.

I was doing (and still do) a similar thing, although local, with a lot of
my web development years ago using a lot of Server Side Includes (SSIs). I
say "local" because using SSIs you couldn't make requests outside of your
domain. But each little piece of the web site was an SSI that did a
specific job (displayed the header, footer, user id, etc). Then building
sites was as simple as popping SSIs (static or dynamic) into your table
design (now DIVs, though).

So I see micro services similar to that, only your requests can be made
anywhere to retrieve information. Maybe even down to something as simple
as providing an image or js library to your application.

In other words, something we've been doing for a long time, and now it's
just relabeled with a "cool" buzz word.. ;)

This thread is a spin-off from the "PHP options" discussion.

I became aware of the term micro-services a few years ago. I'm wondering
how people in IBM i Land define them? Are they particular to a specific
technology stack such as Node.js on Linux?

A number of Google references suggest that they are REST web services

that

have limited scope and can be developed and deployed "independently".

I kind of get the impression that people view them as "cloud provisioned"
REST web services as opposed to in-house provisioned.

What do you think?
