The relevance is that even a 175 LOC project in Java takes up enormous memory and disk footprint -- that the JVM is this super-heavyweight thing that's really just inherently inappropriate for a lot of applications.

The disk footprint was measuring the size of the docker container, who knows what was in it. Something would have to be wrong for 175 lines to require 650MB of dependencies... it could if it were loading all of Spring/Hibernate/etc., but then I'd challenge it wasn't a "microservice" at all.

JDK... 167MB tarball + 330MB uncompressed

But this is a step back to the cold, dead, static systems of UNIX. How about stepping back and taking a look at the dynamic, hackable environments of Lisp?

You should rather ask yourself why Lisp hasn't been able to attract the same large and active community in 5 decades that Go has been able to attract in 5 years.

Argument ad populum.

There have been several blog posts and conference presentations with a similar theme -- "Go is efficient, especially compared to X."

What are these mobile apps that don't have Web backends?

So slap an http api ?

Building native apps is hard unless you are specialized , but puking up some html and json is easy ,hence building a blog is usually good for introduction.

"Code size was reduced by almost half, from 175 lines down to 96." Hm, I how can we take a 175 LOC project as something relevant in any way?

It's merely a positive (to most) data point. Do with it what you wish. Dismissing it outright seems impruduent.

At my organization we have several Java-based services (some of them can even qualify as a form of microservices, if you squint your eyes). We have found that when you have very good developers and you write almost to the letter of the spec, Java can easily provide a stable base (which is probably true of any language/runtime/library).

However, we've been eager to try Go in several places. Believe it or not, what has held us back is the lack of a solid LDAP library. We could/should scratch our own itch and be done with it, we lack the time... still so many things to do! In the mean time, for us, Java support for LDAP is nothing short of stellar; and has been for years.

Until you have enough microservices and each microservice carries its own Go runtime. Then having one JVM suddenly isn't so bad. The problem (as someone else said) is that using Docker may not be the right solution here. There are enough solutions (e.g. servlet containers) where you can run multiple services in one VM, with isolation, and security hardening (using security manager). With regards to memory footprint -…

> With regards to memory footprint - the difference here is that Java uses a minimum and maximum heap size that can be tuned with parameters. This has ... upsides (upper bound on the maximum memory use of a process).

If you're running a Go app in a container, you can use also tune the upper bound on memory use by restricting the available memory for the container.

the only thing that's preventing me from jumping on the Go bandwagon is lack of a nice collections library (a la lodash).

That's due to a lack of generics. There are some workarounds like gonerics [1] -- a clever abuse of import declarations.

Basically Ubuntu 15.04 docker image + openjdk8 + mysqlclient + the service itself

Wow that pun in the title is painful.

Hehe, yes, I'm afraid I have a proclivity for terrible puns. I do think they're somewhat less cringe-worthy that the link-bait titles that are all the rage these days (or at least endearingly cringeworthy).
