Cloud Computing

Cloud computing is a style of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet. Users need not have knowledge of, expertise in, or control over the technology infrastructure in the "cloud" that supports them.
The concept generally incorporates combinations of the following:
  • infrastructure as a service (IaaS)
  • platform as a service (PaaS)
  • software as a service (SaaS)
The image basically sums up the complete cloud-computing platform.

The term cloud is used as a metaphor for the Internet, based on how the Internet is depicted in computer network diagrams and is an abstraction for the complex infrastructure it conceals.

Some of the major players on Cloud computing. Microsoft is relatively new into the platform and relies on its traditional .Net for enabling the cloud, is the solution that actually made the concept popular.
Amazon has come up with excellent cloud computing platform and Google always rules with their policy, 'All good things come for free' !!!!

Imagine my happiness when i found a big big page with many big big examples to solve the problem. The document I am referring to is from W3C, paged Box media . Long story short, I now possess the ultimate secret of rendering the page in any format I want. So here are few tricks I learned from the p

Top four design patterns and algorithm that every Salesforce Developer should know

A few days ago I was speaking to a developer friend, he was asked about a Singleton design pattern and he had no idea about. He spoke about how we developers never talk about patterns. And that time it hit me, we developers do not talk about design patterns and algorithms. There are many design patterns available off the shelf, they talk in detail about the problems they can solve. However, in my experience, I have come across and used the following 1. Singleton This is one of the most common and important design pattern to be used. When initiating objects, we need to make sure only one instance of the object is initiated. In a multi-tenant system like Salesforce, it becomes imperative that we do not hog more resources than needed Lets look at an example trigger AccountTrigger on Account (before insert, before update) { for(Account record :{ AccountMasterRecordType rt = new AccountMasterRecordType (); .... } } public class AccountMaster
