Big Data and its most prominent technical ingredient, Machine Learning, are
all the rage these days, as IT industry is trying to convince companies
technology revolution is underway. ( "If you are not doing it, your
competitors sure are, and by the time you realize it, it will be too late" ).
Data fracking, i.e. Big Data, is 21 century new oil of that will power and
grease stalled industries and reignite growth, or so the story goes.
While advanced analytics (it comes under various names - predictive
analytics, data mining, and data science, more recently) is great and in use

Amazon recently added Oracle database hosting capabilities to its RDS service
offering. You can rent an Oracle database related infrastructure in a
pay-as-you-go fashion now. We are going to explore if corporations should be
utilizing Amazon AWS Oracle Database related services (EC2, RDS ), how it
should be used, where possible savings and potential trouble points are. With
services like Amazon AWS it doesn't matter where your hardware and software
physically is - it could be in a room next to you or in some other country.

Amazon Web Services EC2 Cloud is full scale public data center offering
services that are in many aspects far ahead of ancient practices present in
regular IT environments. Fast provisioning and virtually unlimited scale make
old fashioned server procurement and installations look like what they are -
past century's practices. This article will not deal with usual objections to

reliability, performance etc. since we think that all t... (more)
