1. Faster than rabbits
@BauerVlad, 2014

2. 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?

3. 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
James Gosling, 1991-1995
What's the catch?

7. Java disadvantages
• “Generic” solutions / Tons of code
• High level of complexity in libraries / frameworks
• Poor concurrency model

• Monolithic applications architecture
• High resource consumption
• Poor code hot swapping
• Static typing
Hussars keep silence!

9. PHP: Hypertext Preprocessor
• Original name: Personal Home Page Tools
• Paradigms: imperative, functional, object-oriented,
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)

Server-side rendering
Components:
PrimeFaces, JBoss RichFaces, ICEfaces, Apache MyFaces, Oracle ADF Faces Rich
Client, Backbase Enterprise Ajax, IBM Notes, Sun Java BluePrints, ZK Ajax
Problems with customization

25. 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

26. 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

27. Client-side
• Demand (Hot Google searches):

• JavaScript: about 916 000 000 results
• PHP: about 3 140 000 000 results
