What You Will Learn
• Reduce geographic risk by moving to lower-risk data center locations
• Improve business resiliency through data center facility resiliency
• Increase data center capacity for future business growth
• Improve business agility through increased server, storage, and network virtualization
• Enable clients located anywhere in the world to access core business applications any time under any circumstances
• Roll out multiple active data centers with the capability to localize client traffic
• Increased application performance as seen by end users, be they employees, partners, or customers
• Easily deployed and established a predictable disaster recovery policy, flexible enough to support additions, moves, and changes for any networked application
• Scaled application global availability without massive increases in WAN bandwidth
• Implemented flexible global network policies that provides localization of client traffic without sacrificing the disaster recovery process
Figure 1. Cisco ACE GSS Deployments
• Cisco used the Cisco ACE GSS unique proximity technology that uses Cisco IOS® Software routers to localize client traffic and provides data center persistence required for web-based applications.
• Cisco used the Cisco ACE GSS universal disaster recovery capability to meet Cisco recovery time objective (RTO) and recovery point objective (RPO) requirements.
• Cost savings resulting from localization of client traffic: Using the Cisco ACE GSS proximity technology, which redirects client traffic to the closest device supporting the requested application, Cisco IT has seen a reduction of intercontinental WAN traffic and reduced need for a costly upgrade to the existing WAN circuits.
• Faster response time: Global networked applications that use the Cisco ACE GSS proximity technology see significantly improved application response times and shortened file transfer times. Also, Cisco ACE GSS supports proximity with persistence, so those clients that have been localized always return to the same global application.
• Increased productivity for IT personnel: Norman Fong, network architect for Cisco says, "On the GSS we leverage the role-based access to allow the user community to configure their own proximity and disaster recovery policies. The implementation is so simple and transparent to the user community they believe they have a dedicated GSS solution... This approach allows for greater levels of productivity, because the user community does not have to wait when they want to make changes in the application's global availability or policy."
• Improved application security and stability: With Cisco ACE GSS, applications experience fewer, and shorter, client-affecting outages caused by hardware failure or system maintenance activities. Applications security is enhanced because Cisco ACE GSS can mitigate the effects of a Domain Name System (DNS)-based distributed-denial-of-service (DDoS) attack. This distinctive self-protection capability can be deployed to shield any DNS infrastructure such as Berkeley Internet Name Domain (BIND) services and Microsoft-based client devices along with Microsoft Active Directory.
