Many enterprise IT decision makers are probably currently, or will be shortly, contemplating some type of cloud computing solution that promises to deliver benefits to their operation. After all, cloud computing solutions, when utilized prudently, are hard to resist. As these decision makers prepare to weigh the pros and cons of such solutions, there is one consideration that is perhaps more important than all others: Will this solution enable elasticity among my services and applications? Hopefully the answer to the above question is a confident 'Yes'. A lot of discussion is given to providing virtualized, dynamically scaled resources such as servers, processors, operating systems, etc. and rightfully so. By optimizing the usage and consumption of these infrastructure resources, IT operations can be significantly enhanced. However, these resources are often times j... (more)

Five Reasons to Choose a Private Cloud

As enterprise interest in cloud computing offerings and concepts continues to increase, the number of solutions in both the public and private cloud spaces increases as well. There's been much debate over public versus private cloud, even to the point of debating whether there can be such a thing as a private cloud. I'm not here to debate the latter (in my opinion the location of the service has nothing to do with whether or not it is a cloud), but rather I want to take a look into why consumers would choose private clouds over their public counterparts. During the last several ... (more)

New IBM Software for Amazon EC2

IBM expanded its software offerings on the Amazon Elastic Compute Cloud (Amazon EC2) by delivering a WebSphere eXtreme Scale 7.0 Development AMI (Amazon Machine Image). The Development AMI can be used for development and test of commercially available applications without any IBM charges. It means, users do not pay for the WebSphere eXtreme Scale software, but only for the Amazon EC2 usage charges. In other words, the AMI can be used for as little as ten cents per hour. WebSphere eXtreme Scale provides a robust, linearly-scaling distributed caching platform for the Amazon EC2 env... (more)

A Framework for REST in Java

Not long ago I worked on a team charged with building up a Java-based REST infrastructure. Our goals were to first support what was then an emerging specification for Java-based RESTful services called JAX-RS. Beyond that, we had thoughts of building an entire framework, both server and client, around RESTful services written in Java. Some of the people I worked with on that team are now part of the team that is responsible for an open source implementation called Apache Wink which embodies some of our early ideas and much more. Developers have been implementing RESTful services... (more)

IBM's Smarter Cloud

A recent announcement from IBM signaled the availability of a new offering in the smarter planet initiative: IBM Smart Business Development & Test on the IBM Cloud. One of the newest offerings in the suite of cloud products from IBM, the IBM Cloud provides a public cloud where users can launch and run selected IBM software. As its name implies, the IBM Cloud is especially focused on development and test scenarios. The idea is to let developers and testers quickly spin up both development and application runtime tools, use them, and just as quickly tear them down. Since all of th... (more)
