WOLF Weekly Cloud Sum-up, Sep 23, 2011

Cloud computing is often referred to as a technology. However, it is actually a significant shift in the business and economic models for provisioning and consuming information technology (IT) that can lead to a significant cost savings. This cost savings can only be realized through the use of significant pooling of these “configurable computing resources” or resource pooling. According to NIST, this capability is an essential characteristic of cloud computing. Resource pooling is the ability of a cloud to serve multiple customers using a multi-tenant model with different physical and virtual resources dynamically assigned and reassigned according to demand. Cloud computing economics depends on four customer population metrics:

1. Number of Unique Customer Sets 
2. Customer Set Duty Cycles 
3. Relative Duty Cycle Displacement 
4. Customer Set Load

Tackling the Challenges of Securing the Cloud

By moving the focus of IT applications beyond the confines of traditional corporate infrastructures, business processes are also simplified and streamlined. Some, however, consider the technology “too risky” and question the levels of data security and transparency in the cloud, which has been accused of exposing organizations to unnecessary security risks. It cannot be taken lightly, nor can it go unchallenged.

The secret to cloud success: Get a grasp on SOA

Those IT organizations that move to cloud computing are moving to SOA (service-oriented architecture), whether they understand it or not. Private and public clouds often rely on APIs for their functionality, which are typically Web services that can be combined and recombined into solutions. The result: SOA, at its essence.

Cloud computing market is starting to look a lot like one big data center

An interesting thing has been happening on the way to the fully cloud-ified IT universe in which every company is able to call on as much computing power as it needs, of whatever kind, using whatever software, then return it to the vast, immutable ether, paying later only for what the used of this vast and magical power without being responsible for creating, training, feeding or protecting anything at all.

Cloud computing a serious contender for email services

Companies are increasingly using Software-as-a-Service (SaaS) and cloud computing applications in place of traditional email platforms, it has been claimed. A new report published by Gartner has found that Google's Gmail service is beginning to rival Microsoft's platforms in companies with more than 5,000 seats for the first time. It is likely that cloud email will amount to 20 per cent of the market by the end of 2016 and more than half by 2020.

We hope these short sum-ups on cloud computing will help you to take a more knowledgeable approach towards moving to the cloud. Stay tuned for more sum-ups on in the forthcoming weeks.

Don’t forget to add your comments and suggestions. I will have more around the cloud a week later.
