The Great Cloud Bottleneck: How Capacity Issues Can Kill Your Cloud Project
Grazed from RedmondMag.com. Author: Doug Barney.
Ever fall half asleep waiting for a Web site to refresh or a Web app to respond, or freak out when your cloud mail is down? If so, you understand a fundamental problem with the cloud: Its speed utterly depends on our network connections, be it a WAN access point, the Internet or a private line.
So we’re not all confused with varying definitions, let’s agree on what a WAN is. According to Cisco Subnet, an independent community for Cisco users, "The WAN is a place in the network that aggregates various types, speeds and links running a disparate set of protocols together crossing metropolitan, state and even country boundaries. The largest example of a WAN is the Internet itself, which can be regarded as the public WAN. The primary purpose of a WAN is to connect users and applications connected to various LANs."
WANs and the Internet were getting clogged long before the cloud. Multimedia, Web and video conferencing, surfing, VoIP and unified communications already stress those networks that haven’t been thoroughly boosted.
