Network Latency

Network latency has a significant impact on user satisfaction, and the physical distance between users and servers is the biggest factor in the latency problem. 　　Problems such as application and processing latency can always be solved by adding more computing resources, but long-distance data packets always take time (for example, from London to New York), which depends largely on the physical constants of the speed of light. Because most cloud computing providers are currently located in the United States, the problem of network latency in the American continent can be tolerated by users. But if your big one ...

Reading] AIG Edison decided to adopt the cloud transplant program, and started working with the new core application platform of Salesforce.com in San Francisco last January.   Now, the system can serve AIG Edison millions of customers, more than 3,000 company employees and more than 15,000 insurance dealers and brokers. In this case, Futami says, the company faces two options-replacing all the old apps or porting them to the cloud and running the managed software. More decision making trade-offs, companies tend to ...

Because companies want to replicate large, unprocessed data files in multiple locations: "Big Data" storage continues to affect the WAN. Large enterprises, such as those in the entertainment and media industries, have had to replicate huge image files, video and data in multiple locations, and they are plagued by bandwidth constraints and WAN delays. Wan Latency Obsession: Large data cannot be ignored in order to address the WAN latency problems associated with these large data, data center wide area network (WAN) optimization Vendor Silver Peak BAE announces the creation of an integer with storage vendor EMC ...

Even if MPLS can improve the transmission efficiency of the data center WAN, the delay is still a big problem. Most WAN optimization vendors typically add physical or virtual WAN optimization devices to address problems at the end of each connection, and for them, latency is an unavoidable disaster. This approach is fairly straightforward in the traditional branch-center deployment model, but it becomes very difficult to optimize the WAN connection if the user is on a day-to-day basis in a third-party remote location with IT staff and policies. Tav ...

As you will learn from this article, many users cannot today sort out the types of solid-state disks (SSD) on the market. This analysis of SSD architecture introduces the three main ways to deploy SSD: Inside the array, within the server, and using SSD devices. 　　Each has its pros and cons, including latency issues and performance levels. Few new technologies can simultaneously improve performance while reducing costs. However, the very interesting technology of SSD achieves this goal. Most of the major storage vendors are beginning to provide a full range of SSD products. ...

This article describes the three main ways to deploy SSDs: Within the array, within the server, and with SSD devices. Each has its pros and cons, including latency issues and performance levels. Few new technologies can simultaneously improve performance while reducing costs. However, the very interesting technology of SSD achieves this goal. Most of the major storage vendors are beginning to provide a full range of SSD products. Solid-State storage drives can be deployed in three different forms: array-based SSD is generally considered for deployment in a storage area network;

"Editor's note" Network after years of development, has come to the "post-Cisco" era, software definition network, network virtualization and other nouns have come to everyone, this article focuses on the traditional network architecture and SDN network of similarities and differences, the development of network virtualization, you can see, SDN manufacturers are gearing up, because of " We usually overestimate the changes in the next two years, and underestimate the changes that will happen in the next decade ", the traditional enterprises need to actively face the future changes in the network operation, the author from the Network Transformation and technology transformation in two aspects of the network industry in-depth discussion of the ...

As cloud computing applications grow, more and more users are starting to deploy their million-gigabit networks. In order to help enterprises design, purchase private cloud, public http://www.aliyun.com/zixun/aggregation/13647.html "> Cloud data center structure, Lippis The Ixia Ethernet Data Center Switch Industry assessment was conducted by the FORCE10 and IP network test solution provider, and Dell's S4810 Gigabit switch performed well in the tests. D ...

In the era of big data, IT vendors researching big data focused their research on optimizing the software architecture of big data systems, optimizing business logic, optimizing data analysis algorithms and optimizing node performance, while ignoring the evaluation of network links in the big data environment infrastructure And optimized. This article introduces Cisco's network architecture design and optimization experience in a Hadoop cluster environment. Big Data Hadoop Environment Network Features Hadoop cluster nodes through http: //www.aliyun.com/zixun/aggregation ...

The fastest way to store a computer system is the ram traditionally used primarily as memory. As the access performance of the hard drive has deteriorated over the years, and the cost of RAM has been decreasing, many researchers have been exploring how to replace the hard disk with memory in recent years. As early as the 1980, David DeWitt and Garcia-molina and so on published a main memory database paper. Steven Robbins's article points out that the Turing Prize winner, Jim Gray, is more explicit about the idea that "memory will be a hard drive and the hard drive will become a tape."
