5th International Cloud Expo New York
Last week's post explored federation in the cloud, allowing enterprises to
move workloads seamlessly across internal and external clouds according to
business and application requirements. Advances in federation are good news
for companies considering a move to the cloud since deployments no longer
need to be custom projects and applications no longer have to be tightly
coupled to a particular cloud.
To follow up, there's been lots of discussion recently about the concept of
the "Intercloud," a direction for cloud computing that is closely related to
federation and ties in with much of our work at CloudSwitch. A term
introduced by Cisco, the Intercloud refers to a mesh of clouds that are
interconnected based on open standards to provide a universal environment for
cloud computing. Like the name suggests, it's similar to the Inter... (more)
Many IT managers would love to move some of their applications out of the
enterprise data center and into the cloud. It's a chance to eliminate a whole
litany of costs and headaches: in capital equipment, in power and cooling, in
administration and maintenance. Instead, just pay as you go for the computing
power you need, and let someone else worry about managing the underlying
But moving from theory into practice is where things get complicated. It's
true that a new web application built from scratch for the cloud as a
standalone environment can be rolled out qu... (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)
Every enterprise has a unique network infrastructure for accessing servers
and allowing applications to communicate between components. Various layers
support the management of network addressing, deliver critical services, and
ensure security. The infrastructure includes specific addressing
(sub-nets), address services like DHCP/DNS, identity and directory services
like LDAP, and firewalls and routing rules – all reflecting the specific
requirements and evolution of the given enterprise.
Clouds are not different from the enterprise in this respect; they have
unique networking... (more)
