The expansion of virtualized data centersStarting with this section, the key techniques for how the network architecture within the data center respond to the wave of cloud computing business are explained.Main content1, the structure and defects of the traditional two-layer networkProblems with the 2,STP protocol3, the need for a sophomore network to change4, three pillars--cisco, IETF, IEEE5, the solution: two layer network to increase the control planeCloud computing and the Big Data

Flexible network channelsCloud computing networks require security, stability, and flexibility, this section focuses on the need for cloud computing for network flexibility, how traditional networks evolve at the bottom to support dynamic scheduling of cloud computing resources.Main content:1, Legacy scheme DNS redirection2, traditional scheme route health injection RHI3, new ideas Loc/ids split position and identity separation best solution: LISPThe secrets of network technology in cloud comput

are hosted on the Ethernet link layer and are connected to 2 worlds by a redesigned FCoE control plane (map)Summary This chapter is more content, storage is a relatively independent technical field, so storage media, storage devices are not too much introduction,This paper focuses on the open extended storage architecture in the data center area, and introduces the evolution direction of the mainstream technology of San. The origin and principle of FCoE, realize the idea, for further study. Clo

Cloud computing Applications-Virtual desktopsVirtual Desktop Infrastructure is a server-based computing model, and the VDI concept was first proposed by VMware and is now a standard technical term.With virtual desktops, resources can be managed centrally in the data center, while ensuring that users have access to a complete PC experience. The current delay is the biggest problem affecting its development.Figure Virtual DesktopCloud computing and the Big Data

Big Data Network Design essentialsFor big data, Gartner is defined as the need for new processing models for greater decision-making, insight into discovery and process optimization capabilities, high growth rates, and diverse information assets.Wikipedia is defined as a collection of data that cannot be captured, managed, and processed within a manageable time frame, using conventional software tools.4V features of Big Data: Volume (Mass), velocity (high speed), Variety (multiple), value.Big da

This is the best of times, it is not the worst of times.I am very happy to be born in this time, the vicissitudes of life.Remember that Darwin seemed to have said that the ultimate survival, not the strongest, nor the smartest, but the most adaptable to change.Seen a lot of crosstalk sketches, those who always popular actors, is able to adapt to the changes of the times, always keep up with the audience's preferences, and those short-lived actors, style single, difficult to make a breakthrough i
