This document discusses how virtualization can benefit branch offices. It notes that virtualization in the data center can help deliver applications and services to branch offices more efficiently. Virtualizing services directly in the branch using a virtualization engine allows for centralized management and delivery of a variety of virtualized applications and services to meet branch needs. This virtualized services approach improves the user experience, lowers costs through operational efficiencies, and increases productivity at branch offices.

6. Next Generation Branch characteristics
Datacenter / Cloud Branch
Applications are centralizing, people are decentralizing
Branch Growth, Remote and mobile worker growth
WAN
Challenges with survivability, user experience, security, green
Users need consistent availability, performance & security irrespective of where
applications are
Internet
Data Center/Cloud & Branch IT boundaries continue to evolve
Applications & services continuum between centralized / decentralized models
Branches need a new Service Paradigm

15. Conclusion
• The next-generation branch Infrastructure will provide:
– Flexibility, ease-of-use, lower TCO and business
– Close linkage to cloud-based services with performance
optimization
– Versatile platform for services and application integration
– Remote management, provisioning and monitoring
– Small physical, energy and carbon footprint
Virtualization should simplify, not complicate
