Cloud Computing Journal 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 internal network. 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)

What Does Enterprise IT Really Want from Cloud Computing?

Cloud Expo 2010 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 enterprise IT. 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)

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)

Moving to the Cloud: The Road Ahead

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...
