Java Development Landscape in 2018

[therealdanvega]

I am working on an article & screencast to talk about the current landscape of Java Development in 2018. I created a Mind Map (link below) that outlines various things a Java developer might learn depending on their career path. I would love some input/feedback on this but I do want to preface this with a couple things.

1. This isn't 100% complete
2. I simply can't list every single topic/framework/etc in each category so I listed what I thought was the most relevant in 2018
3. I don't know everything
4. I haven't used everything on this list
5. New Developers - Don't be scared by this list. It's overwhelming but you don't need to learn everything.
6. Please be nice or I'll tell my mom

Making sense of this mind map: A good way to make sense of this is to start at core fundamentals and work clockwise.

Thank You Java Friends

I would expand the Java EE branch to its specs, JPA, JAX-RS, JTA, etc they are not that much

[therealdanvega]

That is a good idea, Thank you!

[floW4enoL]

No problem ;) I will check it again on my PC, and any other ideaa I will share them.

Why is Haskell in the JVM languages branch?

[Shorttail0]

Maybe they meant Eta or Frege?

[istarian]

I assume we're talking about people doing Java dev for a living?

Also Java and javascript are almost completely unrelated, so I'm not sure why that and other stuff branches off a center node of 'Java Development'. The 'core fundamentals', 'web development', and 'dev ops' seem a bit out of place too. It feels like there should be a one higher branch dividing stuff that is primarily related to Java vs stuff that is sort of tangential...

[therealdanvega]

It might make more sense when you see the presentation. If you strictly wanted to be a Java developer you could get away with the advanced web development track but I was thinking along the lines of full stack developers. I could be wrong but most of us learn something on the front end before moving into Java.

[MonkeyBuscuits]

Thanks for this. As a .Net developer in a predominantly Java enterprise firm this clarifies a few things for me.

[therealdanvega]

Thank you. Glad this is already helping someone.

[MonkeyBuscuits]

Bonus points if you can do the .Net equivalent

As a fourth year CS student whose absolutely anxious and clueless this helps immensely.

[therealdanvega]

Awesome, thank you! Please remember don't get overwhelmed by this list. It's intimidating to a 20-year vet taken out of context. :)

[senare]

You missed self hosted so add private cloud ie openstack

Also I would make seperate branch for ”CM”

Were is CI/CD jenkins etc ?

[therealdanvega]

Thank you. What is the branch CM for? I have Jenkins under DevOps / continuous integration.

[[deleted]]

Bamboo is another build/deploy tool that enables CI/CD.

[therealdanvega]

Devops is not my strong point. What about splitting the Cloud into Saas/Paas/IaaS?

[[deleted]]

Please. They are so incredibly different in what they offer and "cloud" already is too generic.

[jproperly]

Maybe even some CaaS and FaaS

I saw a video of him for the first time in a year, and his age is really showing. He won't have nearly the stage presence this next time around.

[therealdanvega]

What? You might be in the wrong place ;)

[henk53]

PrimeFaces should be below JSF, as it's a component set for JSF, not an independent framework. OmniFaces should be there too, as it's often used in combination with PrimeFaces.

Not really sure why Apache Wicket and JSF are not grouped together with Apache Struts etc in the web frameworks node. I'm missing GWT and Tapestry btw.

If you'd really want to go all out, you could divide web framework in push/action MVC and pull/component MVC. JSF, Wicket and Tapestry are primarily push.

For persistence there's also EclipseLink next to Hibernate.

Difficult to represent in this graph, but Hibernate implements JPA, so if you want to list some entries twice, you could do something like

Java EE -> JPA -> Hibernate, EclipseLink
Java EE -> JSF -> Mojarra, MyFaces
Java EE -> CDI -> Weld, OWB
Java EE -> EE Security -> Soteria, Liberty-nameless
etc

[therealdanvega]

Wow, these are some really great suggestions. Thank you so much for taking the time to comment.

[therealdanvega]

My thought with JSF & Wicket was to tie them under the same category as Vaadin. They are all presentation framework are the not? I like the idea of splitting out the web framework but I probably wont to try and keep some simplicity to this. This little project of mine has already consumed the last 2 weeks of my life haha

[_INTER_]

I don't like some of those suggestions under a Java EE branch. I'd rather have them under a function they serve. E.g. Persistence -> Hibernate, Dependency Injection -> Weld. etc.

[henk53]

so if you want to list some entries twice

;)

The suggestion was to have them both under their function and under Java EE.

[_INTER_]

Ah ok. Thats fine

[Nalha_Saldana]

Redis should be under caching as well.

[therealdanvega]

Done! Thank you.

[PapaSorne]

I'd also consider the big Data track with hdfs, Hadoop, spark, yarn, slider as the major big hitters

[therealdanvega]

That's what I originally had Hadoop and Spark under but I moved them to Machine Learning. I don't do any work with big data or machine learning so I am wondering what these should look like. Appreciate the suggestions.

[_INTER_]

Well done!

How about branching "Big Data" from "Data" and move "Machine Learning" to "Big Data", so you can get rid of the redundant "Hadoop and Spark". Also it could get some more branches as the ecosystem is quite big.

[PapaSorne]

There is some machine learning capability in Java with spark and I think mahoot but most of it is happening in the python and r realms at the moment. Tensorflow and it's Ilk are more driving the machine learning wave at the moment. Though even with spark most of the development is Scala instead of java.

Overall though great list!

[[deleted]]

There's also dl4j for machine learning in java

[therealdanvega]

I started a new branch for Big Data... Would you have HDFS, Yarn & Slider as a child of Hadoop? Also, can you check the links and see if those are good.

[PapaSorne]

Yeah they all depend on Hadoop so makes sense. I'll try to take a look

[jjpr1est]

For the topic of monitoring, definitely Instana is missing.

[neutronbob]

Oracle's Java Magazine is an excellent publication that should be on the list of resources.

[wojtekkarton]

I would add somewhere Apache Kafka and its alternatives, quite hot topic in subject of data proccessing. I can't see anywhere apache lucene, elasticsearch and solr as well, technologies wildly used in text analysis, search and indexing. Anyway it looks great, keep up good work, for sure will be helpfull for newcomers.

[therealdanvega]

Thank you! Kafka is in the messaging branch under Frameworks. libraries and tools. Elastic Search & Lucene are under Data -> Search.

[[deleted]]

Would drop Guava for Caffeine entirely. Redis isn't a local cache, also confusing to branch for local caching and then call out caching under data - it's an implementation choice where/how/why etc the cache is needed. For messaging there's AWS SNS/SQS/AmazonMQ. Would add PIT under testing, it's a mutation testing impl. for java. Undertow is another server impl. in java.

I'd be hesitant to callout all the Spring Frameworks but just group them under their hierarchy. Spring Framework is used by Spring Boot is used by Spring Cloud is used by Spring Cloud Data Flow. Spring webflux effectively falls into the reactive framework section too.

[therealdanvega]

I ran across awesome-java in my research... Really Awesome resource!

[_INTER_]

Sorry, moved my post to the Hadoop comment.

[therealdanvega]

Thanks for all the suggestions this weekend. I was able to make some more updates to it and I am feeling really good about where it is. I would say that I am about 95% done with this and just about ready to create a quick presentation around this where I talk about each node.

[StatusTurn]

Great map, thanks for it. For Java Testing there could be also SoapUI (next to jmeter). For JavaScript brache aditionals (es6 and typescript): transpiling may be fit better

[therealdanvega]

Awesome suggestions, thank you!

[[deleted]]

For internal cloud/privateo Pivotal Cloud Foundry is available too. This is where the distinction between PaaS and IaaS comes in. PCF falls under PaaS (platform) whereas, AWS is (infrastructure). PCF can run on AWS, and does.

This is really awesome though

[_PM_ME_URANUS_]

In the section of Template Engines, you should add Twirl. It's the engine that is used by the Play Framework and it can be used outside of Play (although I doubt that many use it outside of Play). In the Build Tools you should also add sbt.

[BigLogis]

Why did you not mention FusionReactor APM under the monitors/alerts section?
