Unit 3: Developing Cloud Services

Blue Cloud, built on IBM’s expertise in leading massive-scale computing initiatives, is based on Notes
open standards and open source software supported by IBM software, systems technology and
services. The Blue Cloud concept grew out of work IBM did in support of its own software
innovators with an IBM innovation portal called the Technology Adoption Program.

IBM provides open source workload, scheduling software called Hadoop to manage its cloud
hardware, which is based on the MapReduce software used by Google in its offerings. It also
includes PowerVM and Xen virtualization tools, along with IBM’s Tivoli data center management
software.
3.4.4 Salesforce.com

Salesforce.com founded in March 1999 is the enterprise cloud computing leader. It is probably
best known for its sales management SaaS, which is also a leader in cloud computing development.
It’s social and mobile cloud technologies along with sales and CRM applications help companies
connect with customers, partners, and employees in entirely new ways.

The company’s cloud computing architecture is called Force.com. The platform as a service is
entirely on demand, running across the Internet. Salesforce.com provides its own Force.com
API and developer’s toolkit. Pricing is on a per login basis. Force.com is an extremely powerful,
accessible and secure cloud platform. It delivers a complete technology stack covering the
ground from database and security to workflow and user interface.
Supplementing Force.com is App Exchange, a directory of Web-based applications. Developers
can use App Exchange applications uploaded by others, share their own applications in the
directory, or publish private applications reachable only by authorized companies or clients.
App Exchange usually offers a huge variety of free applications that can be conveniently used.
Besides the free of cost applications, App Exchange library has other applications that can be
purchased or licensed from the original developers.

A majority of existing App Exchange applications are sales related, financial analysis apps, sales
analysis tools, email marketing systems etc. Force.com can be used by companies to develop
any type of applications they want. In fact, many small businesses have already used Force.com
to develop applications.

Example: In an April 2008, article in PC World magazine quoted Jonathan Snyder, CTO
of Dream Builder Investments, a 10-person mortgage investment company in New York. “We
are a small company,” Snyder said, “We do not have the resources to focus on buying servers
and developing from scratch. For us, Force.com was really a jumpstart.”

3.4.5 Other Cloud Services Development Tools

Amazon, Google, IBM, and Salesforce.com are not the only companies offering tools for cloud
services developers. A number of smaller companies are also increasingly providing these
services.
These companies include the following:

3tera: Offers the AppLogic grid operating system and Cloudware architecture for
on-demand computing. CA 3Tera AppLogic is designed from the ground up to expect
hardware failures and recover applications quickly and automatically.
