What is a cloud computing platform? Is it simply automated provisioning
systems coupled with a resource virtualization, where the workload is policy
driven, and resources over committed and any resource contention handled by
policy driven resolution? As it turns out technologies that provide
provisioning, virtualization and policy enforcement form the building blocks
of a true cloud computing platform, but not any one technology is a cloud
offering in and of it self. IBM’s CloudBurst family attempts to provide a
single cloud solution with an appliance form factor. This paper will discuss,
and draw differences between IBM CloudBurst and WebSphere CloudBurst
So why an appliance? An appliance is generally considered a computing device
with specific function and limited configuration capability. An appliance
delivers the hardware and all the requisite ... (more)
I. Statement of Purpose
The intent of this document is to capture the discussion and provide a
prescriptive approach and consideration towards establishing a Mobile CoE.
This document is also to serve as a Body of Knowledge (BoK) that includes
agreed upon objectives, tasks and various other business and technology
related topics in context of Mobile design. This document is just a draft on
guidelines. The final charter of any CoE is task and responsibility of the
core members of CoE.
II. Intent of a CoE:
Center of Excellence (CoE) is essentially a team of people that promote
Fundamentals: How does WXS solve the Scalability problem?
In understanding the scalability challenge addressed by WebSphere eXtreme
Scale, let us first define and understand scalability.
Wikipedia defines scalability as a "desirable property of a system, a
network, or a process, which indicates its ability to either handle growing
amounts of work in a graceful manner, or to be readily enlarged. For example,
it can refer to the capability of a system to increase total throughput under
an increased load when resources (typically hardware) are added."
Day and day out, we see every technology vendor attempting to position
themselves in the cloud realm and struggling to find a niche in this 'cloudy'
1. Virtualization and Automation are the building blocks of the cloud
computing platform. They alone will not solve any problems.
2. Cloud computing is based on the premise that it is a new model that
accommodates a new services delivery and consumption model. Now the term
'service' is very elusive, and I think this is what it is exploited by every
vendor trying to find that 'fit'.
3. Without a vision and a set expe... (more)
Lately I have been engaged with many clients that are maniacally focused on
reduced costs by means of reduced footprint. In this post, I attempt to
discuss some of my thoughts and experiences towards this trend:
Growth poses a problem: As business grows so does the resulting
infrastructure and primarily the middleware which houses the business logic
and in some cases this tier shares the presentation or the store front with
business logic. So with growth in business either due to larger client base
or new business model implies similar growth in middleware. This consistent
