USE CASE: SHAREPOINT SAAS MIGRATION

Use Case: -  Moving to SharePoint Online (O365) company updates and document sharing. -  Expectation that performance to load the home page would be ~5 seconds globally. -  WAN acceleration was put in place to address when internally implemented with private DC -  Once the rollout started, performance of the application was considered problematic (AGAIN!). -  Of course this was a NETWORK ISSUE, nothing to do with the application or location.

Issue: -  No longer had acceleration device at SP end -  Additional WAN hops -  Limited testing – only from PSL -  Bloated homepage -  Dublin only location -  Lack of application ownership and knowledge end to end

Steps to resolve: -  ThousandEyes to the rescue -  Enterprise Pro Agents installed @ 4 locations -  Clearly presented page load timings for each step, main page access, Auth, and page loading from a location viewpoint -  Identified issues with the page design, numerous JS loading, in place RUM lacked accurate details
