Salesforce.com, the company that offers Software-as-a-Service (SaaS) and Platform-as-a-Service (PaaS) solutions, launched its Dreamforce 2008 conference today, in what they called the cloud computing event of the year.

The conference is expected to gather thousands of attendees, hundreds of speakers, experts and partners, who will witness SaaS and PaaS plans for next year. This will include Force.com, which “reinvents the traditional development, deployment and distribution of any business application with Platform-as-a-Service.”

Force.com was designed to help developers, partners and customers create Web applications on demand, without needing a special infrastructure, and deploy them worldwide as a service. “it’s all about computing in the ‘cloud’,” the company said.

Salesforce.com explained that Force.com allows users to create applications that can then be easily shared, exchanged and installed with just a few clicks through the company’s AppExchange service, which is continuously expanding, offering services to the entire on-demand community.

The enterprise cloud computing company already serves the needs of over 47,000 enterprises and 1.1 million subscribers, and is now looking to redefine Customer Relationship Management (CRM) in the era of cloud computing, as George Hu, executive vice president Marketing, Applications, and Customer Service, said.

Salesforce.com has often reinforced the idea that cloud computing is extremely beneficial, and as a consequence of that, has now officially launched the Force.com Sites technology, allowing customers to expand CRM applications through interactive Web-to-lead forms.

As today’s businesses rely on efficient models to share and collaborate, Salesforce.com comes to meet their needs and help them collaborate entirely online, delivering the same speed, access and efficiency of the Web, the company said.
