Meiosys, a provider of transparent application virtualization and stateful application relocation for Utility Computing, High-Performance Computing and Fault Tolerance Computing, today announced the computer industry's first stateful relocation of a multi-tier application from one server to another without service interruption. Meiosys used a pre-release version of its MetaCluster UC 3.0, which will ship at the end of December, to demonstrate the relocation of RUBiS, an auction site application similar to eBay.com, from one machine to another, under load, while preserving the state and open connections of the RUBiS application. Meiosys accomplished this stateful relocation in a way that was completely transparent to the application and its clients, had negligible overhead (under 1%), did not require any application re-linking, was completed in seconds, and preserved all connections to the application and the memory state of the application after the relocation. The RUBiS application stack that Meiosys relocated was running on top of a JBoss application server using a MySQL database. "Multi-tier distributed applications are quite complex," said Dan Kusnetzky, IDC's VP of system software research. "It is quite a feat to move a running application system from system to system without losing the application system's state or being required to re-architect the solution to use an extensive array of virtual environment software." Stateful application relocation, driven by policies in the MetaCluster product, allows for a dynamic allocation of CPU and server infrastructure to applications, on-demand. In others words, MetaCluster makes the data center dynamic, allowing IT organizations to provision infrastructure at a much higher level (over 4X traditional methods), while actually increasing service quality on applications. By dynamically allocating capacity on multiple machines to applications, MetaCluster dramatically increases data center efficiency, enables stateful failover of applications for high availability and clustering environments, and also allows for manual relocation for on-line maintenance of servers. "Enterprises are faced with ever more complex workloads associated with multi tier applications," said Francois Richard, VP of Engineering at Meiosys. "The challenge is to best provision IT resources while respecting end users' response times, under heavy or spiking loads. As such, IT tends to over-provision infrastructure to applications which results in low efficiency. With MetaCluster UC, resources can be dynamically assigned to the applications at the right time, based on specific application load. In addition, applications can be statefully failed over from one machine to another in HA clustering environments using MetaCluster technology." "Stateful application relocation is a key enabler for next generation data centers," added Jason Donahue, President and CEO at Meiosys. "Platform vendors and software companies can bundle MetaCluster UC into their solutions to allow their enterprise customers to shift their focus from simple application provisioning to true business optimization." As applications can now be easily relocated in a transparent fashion from machine to machine with MetaCluster UC, MetaCluster enables platform and software companies which bundle the product into their solutions to make the data center truly dynamic for their customers. This allows their customers, enterprise IT managers, to shift their focus from simple application provisioning to true business optimization," added Jason Donahue, President and CEO at Meiosys. Background: Established in 2001, Meiosys develops stateful application virtualization and relocation solutions for Utility Computing, High-Performance Computing and Fault Tolerance markets. Meiosys licenses its technology to platform and software vendors who bundle MetaCluster into their on-demand and high performance computing products. Meiosys' MetaCluster product is implemented in production at leading EDA, DCM, Energy and Manufacturing companies in the USA, Europe and Asia. Meiosys is privately held with strategic financing from Alven Capital, BayTech Venture Capital, Credit Lyonnais Private Equity, Cisco Systems, Partech International, Siparex and Wellington Partners.
