The recent announcement from Amazon of the Virtual Private Cloud (VPC)
represents the next big advance in the evolution chain for cloud computing.
Enterprises can now integrate their IT infrastructure with Amazon's vast
computing and storage resources, using a VPN connection from their data
center to their own virtual private cloud which then looks like part of their
Until the release of VPC, companies were left to build applications and
utilize the cloud as a separate and somewhat siloed portion of their
computing environment. In addition to the VPN connection, VPC allows cloud
users to control their IP addressing within the Amazon cloud (previously IT
addresses were assigned randomly). This may sound trivial, but it solves some
tricky problems that made it hard to integrate cloud and internal resources.
Prior to VPC, eve... (more)

Analysts, bloggers and mainstream media have spent 2009 promoting cloud
computing as “the next big thing” that will revolutionize the way
companies buy and use computing power.
But beyond the hype and the C-level interest in an exciting trend, there’s
value to the cloud that appeals to the pragmatic, “show me” nature of
The two main drivers for cloud computing are the same ones that have always
motivated enterprise IT: save money (do more with less) and be more
responsive to business needs. These goals are typically in conflict with each
other, s... (more)
Over the past several years, many IT departments have committed to
virtualization as an antidote to the spiraling costs and inflexibility
plaguing corporate data centers everywhere.
By running applications on virtual servers and consolidating underutilized
hardware, data centers can get maximum value from their equipment.
Virtualization also makes IT more responsive to the needs of the business:
rather than spending weeks or months to provision a physical server, a
virtual server can be launched in minutes.
Virtualization was meant to be the solution to today's data center woes -... (more)
This post is part of a series examining the issues involved when moving
applications between internal data centers and public clouds.
The true challenges in storage and data management in the cloud result from
the diverse and often unfamiliar processes and infrastructures offered by the
cloud providers, including: new provisioning methods, storage properties,
data population and transfer, and systems for data management (snapshots,
clones, replication, backup). The cloud providers define the relationship
between servers and storage and often impose constraints on everything from ... (more)
Over the past few posts I covered a number of key points to consider as you
plan to move to the cloud. These issues are based on our experiences with
many public clouds, as well as what we have learned from working with
enterprises adopting the cloud.
I hope it’s clear that today’s clouds are powerful resources that can be
used to rapidly develop and deploy applications; they provide on-demand
resources and true value. The challenges I outlined in configuration,
storage, networking, and management really come into play when you try to
integrate the power of the cloud with your... (more)
