Faster than rabbits

@BauerVlad, 2014

Questions / Problems

• Why are we so slow?• How to increase development productivity?• How to extend the sphere of projects to develop?• How to develop High-Load web applications?• How to develop small / medium sized projects fast?• What can we do with it?

Java principles

1. It should be "simple, object-oriented and familiar"2. It should be "robust and secure"3. It should be "architecture-neutral and portable"4. It should execute with "high performance"5. It should be "interpreted, threaded, and dynamic”

+ WORA

Spring that you might not know

• Spring Web Services• Spring Data• Spring Web Flow• Spring Integration• Spring Batch• Spring Security• Spring HATEOAS• Spring Social• Spring AMQP• Spring Mobile• Spring for Android

• Spring Boot• Spring XD• Spring LDAP• Spring Scala• Spring Roo• Spring Blazeds Integration• Spring Loaded• Spring Shell• etc.

Java disadvantages

• “Generic” solutions / Tons of code• High level of complexity in libraries / frameworks• Poor concurrency model• Stateful nature• Mutable nature• Backward compatibility• Monolithic applications architecture• High resource consumption• Poor code hot swapping• Static typing

procedural, reflective• Short time to market• Easy integration• Flexibility• Availability of resources

“I don’t know how to stop it, there was never any intent to write a programming language. I have absolutely no idea how to write a programming

language, I just kept adding the next logical step on the way.”(Rasmus Lerdorf)

Problems with customization

GWT?

• Using HTML in GWT - poor• Using CSS in GWT - poor• Separation of concerns - poor• Union of problems• Desktop != Web

• Live examples:• Simba: GWT -> AngularJS• 30-50m to build big projects

Client-side rendering

Rendering

Server-Side• Has expensive (re)deploy• Needs a lot of hardware

resources• Uses expensive caching• Needs additional REST API• Uses needed data set• Has framework components• Can split development team• Has got less JS code

Client-Side• Has instant redeploy• Does not use a lot of server

resources• Uses cheap caching• Has out-of-box REST API• Uses extended data set• Has framework components• Can split development team• Has got a lot of JS code

vs

Client-side

• Demand (Hot Google searches):• Java: about 230 000 000 results• JavaScript: about 916 000 000 results• PHP: about 3 140 000 000 results
