Enterprises should implement it architecture transfer for virtualized cloud computing requirements

Three-tier network architecture in the past decades, the majority of people used the network architecture standard practice. However, today's virtualization and cloud computing applications are very different in form than in the past, resulting in changes in network traffic behavior, highlighting the efficiency of the three-tier network architecture.

Today, for the enterprise, virtualization and cloud computing are affecting the transfer of IT architecture, SSD (solid-state drive) becomes the new trend of enterprise storage application is an example, storage device vendors start to provide SSD flash storage devices, whether it is built in the storage system as a cache or a faster tiered storage architecture, or directly built into the server host, is to meet the challenges of virtualization to propose a new architecture.

Ethernet fabric is also the same trend, this is a network of netcom manufacturers to deal with the virtualization and cloud computing, and proposed a new generation of networking architecture.

Over the past few decades, the enterprise network architecture has not changed much, most people adopt the standard approach of network architecture--three-tier network architecture, through the L2 access layer, the convergence layer and the core layer to build a network architecture that can balance the expansion and management. Such an architecture can be a standard for all to follow, because the need for most applications can be grounded in both expansion, effectiveness and management.

However, this architecture faces the need for virtualization and cloud computing, but it lacks efficiency. The main reason is that the type of virtualization and cloud computing applications is different from the past, resulting in changes in network traffic behavior, thus highlighting the efficiency of the three-tier network architecture.

Today, the general application of the data flow, mainly by the end of the request, the network packet then sent to the back-end server, database, storage equipment, and then back to the data along the road to the use of the end of the network traffic flow mode is north-South longitudinal. However, virtualization and cloud computing environments add more horizontal traffic, for example, a virtual machine moved from one server to another, mainly at the level of the server, but in the three-tier network architecture, the network packet to upload to the core layer, and then down to another server, and each additional layer, The network latency will increase, and the total will affect the virtual machine online real-time switching. and cloud computing applications, the majority of decentralized computing, the use of a data request, often by the different applications located in multiple servers together to produce results, so across the server in the horizontal data transfer increased.

Ethernet Fabric is a blueprint for flattening the network architecture, trying to solve the problem of traditional network architecture, however, the new technology is still not uniform standards, but also need to eliminate the replacement of the existing architecture, so it is still a little early to accept the enterprise, but, Many of the information executives we interviewed agree that this will be an inevitable trend in the future of the network architecture.

The combination of it and business is a subject of great concern to information managers over the years, with most of the view that it will be able to work closely with business and create the maximum value of it, and that it must move away from its passive support role and become more proactive in assisting business units, It is even better to proactively propose how it can create business opportunities before the needs of the business unit. But in this issue of the CIO Talk unit, the New Sun Hing Company CIO Chan has shared a different view, saying: "Manufacturing it does not have to be in front of the business, but to build partnerships with users and pull it forward by users." ”
