Improving App Experience with AVC/WAAS UNIFIED PERFORMANCE MONITOR | AVC | FLEXIBLE NETFLOW & NBAR2 Branch Proliferation of Devices Users/ Machines Private Cloud DC/Headquarters Public Cloud Application Visibility & Control (AVC) 60% of IT Professionals Cite Performance as Key Challenge for Cloud No Probes • Deep packet inspection • Passive monitoring for voice, video, critical apps and best-effort apps • No additional hardware (and included in IOS-AX license) Business-Aligned Privacy Enforcement • No need for complex IP and port ACLs • See inside HTTP flows to identify specific Cloud applications Smart Capacity Planning • Better use of expensive bandwidth • Per-branch and per-application level reporting
- 14. Improving App Experience with Content Caching Extranet HTTP Akamaized Web Content Akamai Intelligent Platform Authentication to Akamai Intelligent Platform Akamai Connected Cache Branch User Network Challenges • Customer’s own content already cached in the Akamai Intelligent Platform • Last mile access may still be an issue • Users access their own and 3rd party content from the branch Akamai Connect Solution • Cache previously “non-cacheable” Internet content inside the branch • Utilizes the breadth and scale of the Akamai Intelligent Platform • Automatically takes advantages of changes in the Akamai Intelligent Platform
