Disaster Recovery In The Cloud, Or DRaaS: Revisited The idea of offering Disaster Recovery services has been around as long as SunGard or IBM BCRS (Business Continuity & Resiliency Services). Disclaimer: I worked for the company that became IBM Information Protection Services in 2008, a part of BCRS. It seems inevitable that Cloud Computing and Cloud Storage should have an impact on the kinds of solutions that small, medium and large companies would find attractive and would fit their requirements. Those cloud-based DR services are not taking the world by storm, however. Why is that? Cloud infrastructure seems perfectly suited for economical

Leveraging a Virtualized Data Center to Improve Business Agility – Conclusion Read Part 1, Part 2… Virtualized Data Center – Keeping it Simple Early designs of cloud computing focused on blades with an independent Storage Area Network (SAN) architecture. This blueprint consolidated the CPU and memory into dense blade server configurations connected via several high-speed networks (typically a combination of Fibre Channel and 10GB) to large Storage Area Networks. This has been a typical blueprint delivered by traditional off the shelf pre-built virtualization infrastructure, especially in the enterprise in private cloud configurations. More recently, hardware vendors have been shipping modular
Virtualization and the emergence of private cloud computing provide today’s organizations with powerful new ways to provide business groups with the computing and infrastructure resources they need—more quickly and cost-effectively than ever before. For many business groups, virtual machines (VMs) can provide precisely the resources they require without those groups having to jump through the hoops associated with gaining access to the same resources delivered through a physical infrastructure. Both the IT team and the business organization benefit from the absence of physical infrastructure, the elimination of long approval and purchasing cycles, and the speed with which virtual resources can
