Cloud computing is becoming a mission critical factor as more corporations move their infrastructures to the cloud. A key to a successful cloud migration is not in the deployment but in the management after you are there. Here are some graphs showing performance over time for some of the most common cloud computing providers. Graphs provided by cloudclimate.com. GoGrid Performance Graph Amazon EC2 US Performance Graph Amazon EC2 EU Performance Graph cloudImpact will be updating these performance graphs periodically and trending the results over time. ...

Types of Cloud Computing

There are several kinds of Cloud Computing service offerings.  Here are the most common ones. Common Services. Some products offer Internet-based services—such as storage, middleware, collaboration, and database capabilities—directly to users. SaaS. Software-as-a-service products provide a complete, turnkey application—including complex programs such as those for CRM or enterprise-resource management—via the Internet. PaaS. Platform-as-a-service products offer a full or partial development environment that users can access and utilize online, even in collaboration with others.... (more)

Sun Microsystems' View on Cloud Computing

“In many ways, cloud computing is simply a metaphor for the Internet, the increasing movement of computer and data resources onto the Web. But there’s a difference: cloud computing represents a new tipping point for the value of network computing. It delivers higher efficiency, massive scalability, and faster, easier software development.  It’s about new programming models, new IT infrastructure, and the enabling of new business models.” Excerpt from  – Sun Microsystems' White Paper on “Taking Cloud Computing to a Higher Level” ...

Main Advantages of Cloud Computing

Availability. Cloud-computing proponents say a system run by a large service provider that has money and redundant equipment should offer more availability than an infrastructure run by a small or even mid-sized company. Application integration and support. The systems generally use SOAP, the Web Services Description Language (WSDL), and other nonproprietary Web service protocols, many XML-based. This enables easy interaction with and support of legacy resources and other infrastructure services. Flexibility. Most cloud-computing vendors don’t require contracts and let users work... (more)

Cloud Computing – The Stormy Side/The Upside

Provided below are two quotes, one from Larry Ellison of Oracle and one from Andy Isherwood of HP (both from 2008 so maybe their perspectives have changed).  Not everyone, even those that would be serving this new Cloud Computing environment, are convinced that Cloud Computing is a new and improved way to do business.  In fact, these two are claiming that they are already doing it.  Luckily for us, not everyone is of the same mindset as these two but clients do have concerns and in some instances, rightly so. “The interesting thing about Cloud Computing is that we’ve redefined C...
