Enterprises must rethink network management in the cloud computing world. This new reality is driven by the rise of software defined networking, the virtualization of everything and a business imperative to create and deploy even newer information delivery models. With the entire infrastructure stack now fully programmable, the need to integrate the network with cloud compute services is essential. Another important environmental change is that both servers and applications have joined data with respect to mobility. This leads to an increased need to categorize those assets and apply appropriate security controls with respect to business/mission functions, data user role, location of access, legal/regulatory guidelines and user devices. In meeting the challenges of mobility and globalization, enterprises must address their lack control or complete visibility into the networks they use.
Organizations often lose the economic and operational benefits of the cloud if the network provider lacks the agility afforded by network management automation. Requirements to support cloud brokerage and to bridge services between different cloud service vendor marketplaces are also coming to the forefront. Network performance expectations that are driving more advanced network management requirements include:
- Data-intensive analytics;
- Parallel and clustered processing;
- Telemedicine;
- Remote expert consultation and collaboration; and
- Community cloud services.
- Network latency management - Acceptable response times on the web have steadily been decreasing. While 10 seconds used to be considered reasonable, a 2009 study showed that 40 percent of visitors will abandon a web page if it takes more than three seconds to load. Interactions that take 1 second or less maintain a user’s seamless flow of thought.
