It is quite a remarkable feeling to watch as the pieces fall into place and the picture, anticipated for so long, is finally revealed in all its splendour. ...
EUCALYPTUS - Elastic Utility Computing Architecture for Linking Your Programs To Useful Systems - is an open-source software infrastructure for implementing "cloud computing" on clusters. The current interface to EUCALYPTUS is compatible with Amazon's EC2 interface, but the infrastructure is designed to support multiple client-side interfaces. EUCALYPTUS is implemented using commonly available Linux tools and basic Web-service technologies making it easy to install and maintain.
Platform-as-a-Service (PaaS)
The VMforce collaboration is VMware’s first public implementation of Platform-as-a-Service (abbreviated as “PaaS”). PaaS offerings aim to make developers incredibly efficient by hiding many of the complexities that they face in typical enterprise IT environments such as:
* Waiting for the provisioning of physical machines and their software
* Changing your code to work with the specific middleware components your company uses
* Handling code modifications that may be required as the middleware versions change
* Dealing with new environments as your code moves from development to staging to production
* Frustrating interactions with the separate operations team when things aren’t working well
PaaS offerings typically offer add-on services available for developers to incorporate into their applications. These include capabilities such as location-based services, identity management, tweeting, chatter, search, and many forms of data storage. The developer efficiency and application richness to be gained through PaaS offerings is clear and we see it as one of the major trends in cloud computing. Today’s PaaS offerings are not without challenges though, and we believe VMware is in a unique position to attack these challenges and help bring PaaS to the mainstream.
"Nel 2011 il social networking sarà più diffuso della collaborazione face-to-face".Nonostante i progressi delle tecnologie di internet, questa affermazione per la gran parte dei cosiddetti knowledge-worker non si è ancora avverata. Anche nelle imprese piccole, in quelle più avanzate...
Amazon Elastic Block Store (EBS) enables a single Amazon EC2 instance to attach to one or more highly available, highly reliable storage volumes of up to 1 TB of data each. Once attached, applications on a single Amazon EC2 instance can read or write from the Amazon EBS volume similar to a disk drive. With Amazon EBS, an Amazon EC2 instance can now be terminated without losing the data that resides on the Amazon EBS volume. One use case involves running a relational database within an Amazon EC2 instance, but maintaining the data within an Amazon EBS volume.
