Platform-as-a-service provider Longjump is looking to help those wary of the cloud after announcing that its on-demand Business Applications Platform can now be licensed and used within a customer's four walls.

"Now we are shifting gears. We've found that some large companies are not ready to push all their information into the cloud," said Pankaj Malviya, founder and CEO of Longjump. "We are trying to solve this problem."

So customers and ISVs can now opt to license the software and install it in-house to create so-called private clouds.

Malviya explained that the Business Applications Platform lets IT and business collaborate to create applications that business users, in turn, can easily customise. Longjump also provides a unified interface to integrate business data and create transactional applications, according to the company.

By installing the software in-house, IT shops can take control of otherwise hosted functions, such as multi-tenancy, application delivery, and portability, Malviya added. Likewise, ISVs and SaaS providers can use Longjump's Business Applications Platform to add more features and capabilities to existing services, he said.

This has been a busy week for cloud computing. Hewlett-Packard on Tuesday unwrapped Cloud Assure products and services to improve the availability, performance, and security of cloud-based resources. And on Monday, a number of vendors, including Longjump, published the Open Cloud Manifesto.

Earlier in the year, Longjump offered a "Database as a Service" (DaaS) product is aimed at organisations that want a web-enabled relational database management system, without the hassle of provisioning a server and dealing with data access, availability, backup and security issues.
