Implementing a virtual Data Environment: WAN optimization is the key

http://www.aliyun.com/zixun/aggregation/13868.html "> Software definition Network may bring the most fundamental change to the enterprise to date. In the near future, companies will be able to run the entire data environment on a fully virtualized infrastructure that is likely to be distributed in remote locations.


This also allows us to make some assumptions about the data network. For example, in a broader sense, subdivide the edge of the datacenter as well as the WAN and local area networks.


In most cases, businesses use cloud computing to limit storage operations. However, the growing reliance on SaaS, PAAs, and IaaS architectures can drive enterprises to deploy higher-order applications, even the most critical applications, such as e-commerce and financial statements, across widely distributed architectures.


at this point, companies will encounter many problems. First, the WAN is not designed for highly dynamic data traffic pouring into the local area network. Traditionally, WANs divert large chunks of data into field offices and remote areas, where local infrastructure is assigned to designated locations. Second, wide-area services are not cheap. Although worldwide bandwidth should be sufficient to meet foreseeable future requirements, the general enterprise is concerned about the rising cost of WAN traffic, even with the deployment of powerful optimization technologies.


but from the real capitalization of the way, where there is need, there will be people find ways to make money. The need to improve WAN performance for cloud computing applications is driving a large number of start-ups to develop a wide range of innovative solutions.


For example, cloud computing provider Axcient recently introduced a new synchronization protocol designed to speed up the data transfer of its service products. The system has a local device for tracking block-level changes within the enterprise environment, reducing the volume of data in the cloud to 90%, and shortening the backup and recovery process from hours to minutes. Axcient said that next month they would integrate the agreement into their general cloud services product line, and that existing customers would not have to pay additional fees.


At the same time, Pertino is trying to simplify WAN operations by adding more functionality to the edge of the network. This network services virtualization (NFS) system shifts traditional edge functionality, such as mobile VPN functionality, malware detection, monitoring, and even WAN optimization itself, into cloud computing services, which it serves as a service-based approach to network file virtualization (NFV). By decentralizing the network library and providing uniform configuration, data collection, policy execution, and other tools across multiple data environments and on multiple devices, this will not only reduce the complexity of the local infrastructure, but also increase application and user functionality. In Pertino's latest version of the Cloud network engine (Cloud receptacle Engine), NSV is a key component.


In addition, Cloudopt has also withdrawn from its new speed, a service offering, which has increased data transfer speeds of about 90% to the mainstream cloud services, such as AWS and EC2. This allows the database to be nearly real-time across the region, as well as full day backups and high-speed uploading of large data volumes to available cloud computing resources. In addition, the system can be accessed via a simple installation of Windows or Linux clients without the need for hardware or software devices or any network experience. Cloudopt recently expanded the service to the West coast of the United States and the European Union region.

The rise of the
WAN optimization service illustrates some of the key issues that cloud computing can use to address it. WAN functionality is already an important part of the enterprise Data Environment, and WAN functions play an increasingly important role as enterprises get rid of the traditional data center infrastructure. This means that it will become more and more similar to the LAN in terms of its performance.

The
data world is getting smaller, and as businesses become more reliant on cloud computing, all the infrastructure will soon become a local facility.
