Amazon Web Services is a global IT infrastructure platform that runs even the
most demanding, mission critical corporate applications and databases.
Industry heavyweights like Oracle and Microsoft are trying to catch up with
the Cloud technologies that AWS started pioneering back in 2002. All major
industry players now realize Cloud can’t be ignored anymore. It is obvious
that Cloud paradigm shift is as dramatic as the move from mainframe to
client-server. Companies of all sizes are hurriedly building private Clouds,
using public Clouds, or building hybrid private-public Cloud environments.
AWS Architecture and Major Building Blocks
New services and features are constantly added to AWS. Providing a complete
overview of AWS is thus a never-ending job. I will deal with services that
are of biggest importance for corporate users throughout this book.

Most of enterprise class shops today run their Oracle databases on either
HP-UX, AIX or Sun OS operating systems. Is it possible to move these
databases to the public cloud, and, if so, who are providers who can help
with such a move?
Public cloud services are closely related to virtualization i.e. usage of
various flavors of popular Virtual Machines (VMware, XEN). VMs are one of
major ingredients giving cloud services such great characteristics as
scalability, on-demand instant provisioning and deprovisioning of resources.
Virtual Machines are able to run many guest operating s... (more)

accessible by CPU. There is a long history of academic research on how to
best utilize relatively abundant computer memory. This research is becoming
increasingly relevant as databases serving business applications are heading
towards memory centric design and implementation.
