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)

Moving to the Cloud: How Hard is it Really?

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 infrastructure. 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)

Has Virtualization Solved the Data Center Crisis?

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)

Moving to the Cloud: Key Considerations for Cloud Storage

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)

Key Considerations for Cloud Networking

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)
