Apache Hadoop is a software framework (platform) that enables a distributed
manipulation of vast amount of data. Introduced in 2006, it is supported by
Google, Yahoo!, and IBM, to name a few. At the heart of its design is the
MapReduce implementation and HDFS (Hadoop Distributed File System), which was
inspired by the MapReduce (introduced by a Google paper) and the Google File
MapReduce is a software framework introduced by Google that supports
distributed computing on large data sets on clusters of computers (or nodes).
It is the combination of two processes named Map and Reduce.
Note: MapReduce applications must have the characteristic of "Map" and
"Reduce," meaning that the task or job can be divided into smaller pieces to
be processed in parallel. Then the result of each sub-task can be reduced to
make the answer for the original task. ... (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
HTTP session management is a function offered by Java Enterprise Edition
(JEE) application servers. It allows JEE applications to store state
information about a given user across many HTTP requests. The JEE
specification provides an API to store and retrieve information specific to
the given user. WebSphere application servers and other competing products,
provide session replication functionality. This is normally done either by
writing to a database or through memory-to-memory replication technology.
These approaches while extensively used today, have operational challenges ... (more)

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)
