Cloud Services for Universities & Colleges

Many Universities and Colleges are moving to the Cloud Services to save costs and provide more facilities for the students.

Curtin University, Perth Australia moves more services to the Cloud with Windows Azure.
Copenhagen Business School moves to the Cloud. They recently switched their student email to the Cloud, using Live@edu.

DFEEST (Department of Further Education Employment Science and Technology) wanted to build a new messaging platform for their 85,000 staff and students, either using their existing Novell Groupwise solution, or using an external email service. They evaluated Google & Microsoft and chose Microsoft's Live@edu. The big benefit for DFEEST is that they're saving money, at the same time as delivering a better services to their users.

The Business School at Brno University of Technology, in the Czech Republic, is one of the universities moving to Cloud services, to enable 4,000 students to connect to their learning whilst they are away from campus. They're using the Microsoft BPOS (Business Productivity Online Services) system to connect e-learning to their students in employment, and in other countries including the UK and the US. What they've found is that it gives their students more opportunities for learning, at the same time as helping them deliver a more flexible service within their limited IT budget. And a significant result for them is that they are able to do this with no more staff resources - leaving them to focus on the quality of teaching and learning.

The School of International Relations at the Economics University in Prague is another of the universities moving to Cloud services, as they have moved students studying IT management to the BPOS Cloud services.

By choosing to move to the Cloud, all these universities have claimed to have speeded up their deployment, which in turns speeds up access to educational resources for their students. They've also reduced their cost of ownership, by not having to rely on the existing university infrastructure.

Universities and Colleges are becoming a big business hub for Cloud Service Providers and the competition in this segment is heating up very rapidly!

How did Cloud Computing evolve?

There were a number of dynamics involved in contributing to the evolution of Cloud Computing. Virtualization technologies, high-bandwidth internet & communication technologies, delivery of enterprise apps, software inter-operability standards, Web 2.0 were some of the key influencing factors for the emergence of the "CLOUD" world!

In 1999, the face of Cloud Computing entered the corporate world with the introduction of SalesForce.com to deliver Enterprise Applications over the internet. This marked the beginning of Software As A Service (SaaS). In 2006, Infrastructure As A Service (IaaS) and Platform As A Service (PaaS) were introduced by Amazon's Elastic Compute Cloud (EC2) commercial web service. In 2009, Google & Microsoft entered into the foray of offering enterprise application services!

Is Cloud Computing the same as Grid Computing?
Not really! Grid Computing uses distributed virtual machines to usually complete a focused single large task, whereas Cloud Computing also uses distributed virtual machines to to complete different types of tasks!

Is Cloud Computing the same as Software As A Service?
Not really! Software As A Service (SaaS) is a software that an organization can purchase and use & it can reside on the user's machines or machines owned by a service provider. SaaS is one of the sub-sets of Cloud Computing.

Is Cloud Computing the same as Virtualization?
Not really! Virtualization can be used to implement Cloud computing.

Is Cloud Computing the same as Service Oriented Architecture?
Not really! Service Oriented Architecture (SOA) supports data exchange among different applications that are a part of a business process.

All the above perceived synonyms (not exactly synonyms!) are used with reference to Cloud Computing, but they should not be confused with Cloud Computing as they are sub-sets or bits & pieces of the Cloud Computing world!

More on this tomorrow!
