Optimizing Network Connectivity to your Data Center
3 likes1,085 views
This document discusses optimizing network connectivity to data centers. It describes how enterprise networks have become more complex with connections to cloud providers, SaaS applications, mobile users and branch offices. This lack of clear boundaries creates visibility challenges across different network segments. ThousandEyes provides visibility into data centers, WANs and the internet to help monitor performance, identify issues in specific locations or with particular ISPs, and troubleshoot connectivity problems collaboratively with service providers.
