Our introduction to sMash


sMash Overview

• Agile web application platform for developing and running modern web applications.

• Simple environment for creating, assembling and running applications based on dynamic scripting language (PHP, Groovy, Ruby)

• Application programming interfaces optimize for producing REST services

• Rich AJAX based web user interfaces• Integration mash-ups and feeds

A complete platform for developing, assemblingand executing Agile Web 2.0 apps quickly and simply.


Why WebSphere sMash?

• Developers want to:–Build Web apps quickly.–Re-use and combine existing apps simply.–Take an Agile approach to Web app development.

•Quick reaction to change•Cost-effective development•Ease of deployment

Speed, Simplicity, Agility

• Developers are adopting:–Dynamic scripting languages for application logic (PHP, Ruby,

Groovy…)•Low barrier to entry, high productivity•Enable “Search, copy and paste” style development

–REST, JSON to tie Web Apps together•Simple, works well with Ajax


WebSphere sMash – Three Mantras

• Speed– Dynamic scripting languages – Fewer lines of code– Brower based tooling

• Simplicity– Leverage preexisting content– Use the web as your SOA platform– Visual assembly style development

• Agility– Small footprint– Easily modify your application– Restart the server in seconds


sMash Prototype/Demo Overview


GlobalLogic Project Resourcing Systemusing sMash

• Ability to map existing GlobalLogic resource skill sets and to customer specific requirements.

• Ability to forecast customer requirements, translate the same into future revenues.

• Customer Project Dashboard

• Ability to create an inventory of skills and figure out what needs to replenished.


Project Wireframes


sMash Feature Ratings

- GlobalLogic’s Viewpoint


Rating Score Terminology

Rating Scale What we are implying!

***** It is unique in this functionality. Standout from existing options. Love it!

**** Big Plus.

*** Very good implementation; and others have it too.

** Good implementation, but others seem to do it better.

* Well, sMash does not have any of this category! So let us skip this.


Highlights - I

No. Key Highlights GlobalLogic Rating

1Convention over Configuration

Allows developers to focus on writing useful code without the distraction of dealing with complex configuration files.

****

2Focus on RESTful Architecture

Increases the interoperability of the components. ***3

Loosely coupled by design

Enables componentization and extensive code reuse *****

4Enhanced Performance

All the server side scripts including PHP runs on Java Virtual Machine (JVM), which is very mature and stable

*****

5Application-centric runtime

Write the app, run it, and it’s ready for use. No need for a separate application server

****

6Scripting Languages

Low barrier to entry (PHP, Groovy) ****

7Trivial Deployment

Very easy to move an app to other machine : zip, copy , run **


Highlights - II

No. Key Highlights GlobalLogic Rating

8Modular Architecture

Features and pre-build services downloaded as required ***

9

Browser-based tooling for client and server-side development

Includes visual tools to simplify Web application interoperation

****


Non-JTA Support

(Assuming here that is an alternative which sMash is proposing in this scenario)

• Considering that sMash does not support JTA transactions, its ability to build products which has Distributed Transactions that occurs across multiple resources is an area of concern.

– Saw this as a big concern in the message boards as the impediment to build serious applications in sMash

No Longer Valid

!


Some Miscellaneous Limitations

– Not an Open Source– Not so easy to learn, requires experience developers– PHP implementation does not seem to be complete.– Error messages are too generic

• When things go wrong, it’s difficult for users to determine the reason and get things working. Documents needs to be enhanced to ease this pain out.

• For example, some commands (ex model_sync) had no message when an error occurred and other had messages that didn’t give much indication of what to do to fix the situation (ex. zso failed)

– Browser dependency to use AppBuilder, only supports Mozilla Firefox


sMash vs Ruby On Rails (RoR)


sMash Vs. RoR

• sMash seems to be providing an easier approach to configure security rules to secure the application (as compared to Java, RoR, PHP)

– For example – in RoR these rules needs to be programmatically implemented; whereas sMash facilitates the same by adding the rules in the configuration file.

• sMash easily allows you to add various types of Authentication modules without changing the authentication model. Again, this needs to be programmed in RoR.

• sMash rides on the proven and tested and matured Java VM as compared to RoR which is still in its infancy.

• By default, sMash comes with DOJO JavaScript library which is a very heavy library. RoR comes with Prototype which is much lighter.

• RoR comes with three application environments (development, test, and production). All these three come with pre-set configurations. This seems to be missing in sMash.

RoR and sMash API Integration Comparison

Key Differences• Very high security mechanism used by sMash to provide API services to the Third Party Application.

• In RoR, we need to write our own API for handling the security mechanism while sMash handles implicitly.

• Need to create a Flickr API in RoR where as in sMash APIs automatically handled in resource model.

RoR and sMash App. Initial Deployment Comparison

Start mongrel services and Restart Apache

Install Ruby, gems and rails

Install Apache and Mongrel App Server

Install Database and Setup Apache

Zip RoR Application

Copy the zip file to the server and Unzip the Application

Load Database Schema into DB

Run the Application

Ruby On Rails IBM WebSphere sMash

Install JDK, require database

Zip the sMash Application

Copy the zip file to the Server and Unzip the Application

Resolve the dependences (zero resolve)

Start the Server (zero start )

Run the application

Key Differences• It takes approx. 4-5 hours to setup the RoR server while sMash takes about 20- 30 minutes.

• RoR requires dependencies like ruby engine, gems installation etc while sMash implicitly resolves all the

dependencies by executing zero resolve command.

• RoR application requires resources having some experience of server configuration while sMash application can be easily deployed by any users.

How does sMash fit in with other Programming Frameworks?


Thumb Rule for Time Estimations

• Thumb rule for Estimations (for Web 2.0/Community-based application)

Java, .NET (C#) 8 – 9 months

PHP 7 months

RoR 5 months

sMash 3 – 3.5 months


Thumb Rule for Cost Estimations

Effort CostExtreme Scalability

CostsTotal

RoR100K * 5 months = $500K

3*(Server Costs) == ~$530K

sMash

100K * 3 months = $300K

+ License Fee = $10K

===================

Total = $310K

2 * (Server Costs) +

IBM Websphere License Costs

== ~$345K

• Thumb rule for Project Costs Calculations (for Web 2.0/Community-based application)• Assumptions –

– $100K Monthly Burn Costs– Server Costs == $10K/Server– IBM Websphere License Costs ~ $15K
