Mikael Lofstrand, chief technologist of Networking Technologies for Sun’s Global Sales and Services organization, has written a 27-page Sun BluePrints article on Sun’s VeriScale architecture, stating it provides an excellent foundation for cloud computing and can be implemented as an overlay to create a virtual infrastructure on a public cloud, or it can be used to implement a private cloud. He details VeriScale’s defining principles, underlying components, interactions and advantages. Applicable real-world scenarios are also described.

Targeted at technical IT managers and datacenter system architects, this article assumes that the reader has a good understanding of network centric datacenter architectures and modern networking concepts.

The following topics are addressed:

• "Requirements of a Scalable Datacenter" describing the requirements that are addressed by the VeriScale architecture.

• "VeriScale Architecture Overview" describing the automation layer and functional components of the VeriScale architecture.

• "Project OpenSolaris Dynamic Service Containers (OpenSolaris DSC)" describing the components of OpenSolaris DSC that are used by the VeriScale architecture.

• "Service Delivery Network (SDN) Architecture and VeriScale Automation" describing how the SDN architecture is used to implement the VeriScale automation requirements.

• "Network Optimization Through Distribution" describing how the VeriScale architecture can be used to distribute and optimize application deployment and load-balancing.

• "Proof of Concept for the VeriScale Architecture" describing a proof-of-concept (POC) that was implemented to verify the feasibility and utility of the VeriScale architecture.

• "The VeriScale-Enabled Business Process" describing how the Veriscale architecture concepts can be applied to business processes in a software intensive enterprise.

"The primary requirements of the VeriScale architecture are scalability, flexibility and efficiency, and the primary mechanism the VeriScale architecture uses to deliver on these requirements is POD and container self-sufficiency," Lofstrand concludes. "Self-sufficiency is achieved, to the extent possible, by encapsulating each service within a payload with the full range of capabilities it requires, while minimizing the need for external, centralized resources. Once delivered to any suitably-capable container in a POD, these payloads -- applications, application platforms, or entire VMs -- can configure themselves and provide the useful function they were designed to provide with minimal support from central resources. In addition, self-sufficiency provides additional benefits including network optimization and improved datacenter cost-efficiency."
