A common feature of cloud computing solutions is that they enable
self-service access to the services they provide. This enables users to
directly procure services from the cloud, and it eliminates the need for more
time-consuming, labor-intensive, human-driven procurement processes familiar
to many in IT.
That's not to say that a cloud computing solution should provide its services
in a free-for-all manner, letting any user take any action within the system.
There should be strict controls over the services users have access to and
the actions they can perform with those services. This is the only way to
ensure that such solutions can actually stand up to the rigors of an
That being said, the WebSphere CloudBurst Appliance strikes a nice balance
between self-service access and security. This balance enables WebSphere

Many of you are no strangers to virtualization. In fact, lots of you have
been doing it in some form or fashion since the mainframe days.
Virtualization is probably as hot now as it ever has been, thanks in part to
the cloud fervor, but also due to the fact that it is making its way up the
stack. For so long most of the virtualization focus was at the operating
system layer, but now we see many examples of virtualization at the
application and application middleware layer. Virtualization's march up the
stack necessarily brings with it an increasing complexity, and thus the
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)
The WebSphere CloudBurst Appliance can bring speed and agility to test
organizations by drastically increasing the pace and ease with which users
interact with WebSphere Application Server environments. I recently got a
chance to catch up with IBM's Robbie Minshall. Robbie is a WebSphere Test
Architect, and he is responsible for a team of testers that harness a lab of
over 2,000 physical machines to put our WebSphere Application Server product
through some pretty rigorous testing.
Toward the beginning of 2009 Robbie’s team started to leverage the

In many cases the industry talks about cloud computing being a new and
optimized approach to delivering IT services. From the point of view of
application developers, cloud computing offers dynamic platforms that equip
them with the capability to deliver their application in an on-demand
fashion. Applications running on a cloud platform scale up and down to meet
the needs of its users. So, in the face of this new delivery model for
applications, should application architects and developers expect this to
have an impact on application architecture and design?
There are indeed con... (more)
