CCSK Domain 1 : Cloud Computing Architectural Framework

CCSK Domain 1 : Cloud Computing Architectural Framework

What is Cloud Computing?
Cloud separates application and information resources from underlying infrastructure and the mechanisms used to deliver them.

Cloud enhances collaboration, agility, scaling and availability and provides the potential for cost reduction through optimized and efficient computing.

IBM UML Certification – Section 1

Section 1: UML and the Modeling Process (20%)

  1. The Unified Modeling Language
  2. Process an Visual Modeling
  3. Analysis and Design Key Concepts

The Unified Modeling Language (UML)

The UML is a language for specifying, visualizing, constructing, and documenting the artifacts of software systems, as well as for business modeling and other non-software systems.

Analysis and Design Concepts

Analysis emphsizes an investigation of the problem and requirements, rather than a solution. For example, If a new computerized library information system is desired,how will it be used?

Requiredment Analysis : An Investigation of the requirements

Object Analysis : An Insestigation of the domain objects

Design emphasizes a conceptual solution that fulfills the requirements, rather than its implementation. For example, a description of a database schema and software objects.

Object-Oriented Analysis and Design

During, object-oriented analysis, there is an emphasis on finding and describing the objects or concepts in the problem domain. For example, in the case of the library information system, some of the concepts include Book, Library, and Patron.

During object-orientied design, there is an emphasis on defining software objects and how they collobrate to fulfill the requirements. For example, in the library system, a Book software object may have a title attribute and a getChatpter method.

Finally, during implementation, design objects are implemented, such as a Book class in Java

public class Book{
private String tile;
   public Chapter getChapter(int pageNumber){....}



Spring Primer

Spring is Framework for enabling the use of Inversion of Control (IOC) or dependency injection.

Dependency Lookup -Application logic is in control of exactly what resource is acquired and create a hard dependency on some other class in the process. Check the below snippets of code on dependency lookup.

Auth auth = AuthFactory.getInstance(); or  Auth auth = new AuthImpl(); or Context based lookup.

Dependency Injection – solves the problem by removing the hard relationship with the classes. It helps unit testing the complex application and move application logic from one environment to another. Spring use the Don’t Repeat Yourself (DRY) Principle. This encourages developers to create logic once and only once. Use POJO – standard helper and library classes.

Aspect-Oriented Programming (AOP) – an approach to a set of problems that do not fit into Object Oriented Programing (OOP) to problem solving. The use of an AOP framework allows a solution to a problem to be applied before and after the invocation of various externally identified method calls. Example of Spring AOP is the declarative transaction management library.

With use of declarative transaction management,

public class AuthServiceImp extends ServiceImpl implements AuthService {
 public User createUser(){
           return Use());

Examples of AOP – managing transactions, security and providing auditing and logging info.

Spring libraries supports all of the Java EE – manage JTA transactions, connect to db, enforce security, send email, schedule operations, manage JMX, generated reports …list goes on.

Spring MVC – divided between views, controller classes and the model.

Views are JSPs, controller classes are provided that supports basic forms to any type complex form. you can chose the impl for the model.

Transfer classes (form beans) are conventional POJOs and validation framework is both POJO and simple to configure.

Spring Web Flow – model your application behavior as a state machine. Application resides in various states and events are raised to move application between these states. This is suited to more dynamic problems. ease of design – State machines are easy to model as diagrams.

Spring Portlet MVC – supports JSR 168 development

Eclipse Web Service Tutorial and Axis2 Setting

I was developing a simple webservice in Eclipse based on the Tutorial available in and had issue with running it. I finally found that the Eclipse IDE (Galileo) sets the wrong webservice environment that causes all this issue.

Eclipse tutor


You can fix it by going to windows ->preference->Web Service -> Server and Runtime -> Web Service Runtime

Set it to Apache Axis2 instead of Apache Axis
