Original article:Http://www.yeeyan.com/articles/view/pestwave/26832 Rackspace recently released a survey on cloud hosting. The company visited 1500 British and U.S. small and medium-sized companies and asked if they knew what cloud hosting was and whether they planned to use cloud hosting in the future. The results are surprising. The most important finding is that there is a big gap between small and medium-sized enterprises in their acceptance of c

Background and overviewSwift was originally a highly available distributed object Storage service developed by Rackspace, and in 2010 contributed to the OpenStack open source community as one of its initial core sub-projects, providing virtual machine image storage services for its Nova subproject. Swift is built on a less expensive standard hardware storage infrastructure, eliminating the need for RAID (redundant array of disks), enabling high availa

: Ubuntu Server.Like Rhel and SLEs, Ubuntu also offers technical support and product certifications, but its resource reserves are not as rich as Red Hat and SuSE. On the other hand, however, Ubuntu is easier to manage when performing simple server tasks.

, tracking, reporting, and so on. Patching systems are similar to fire extinguishing, where users should isolate worms or viruses on the network segment before initiating the patching process. Rackspace's CTO, Mr. Engates, believes that patching routers and firewalls are very similar to the version of the upgrade software. The company is staffed by a network engineer to track vulnerabilities in firewalls and routers. After a patch is identified, the engineer notifies the IT director that if the

machine. By analyzing the log, you find the slowest place where the queue machine handler is located, which is the bottleneck. With two actual pressure-measurement simulations, it is not surprising that we find that the system at the extreme pressure, the first to reach the bottleneck is not the database write, but cache update. Therefore, in order to improve the throughput of the queue processor under extreme pressure, we have optimized some of the cache updates. Challenge 3: How to ensure t

. Carriers need a fast and cost-effective way to provide advanced network services for enterprise customers. Therefore, they need to abandon this time-consuming manual service deployment model, in addition, it is necessary to quickly provide new network services to improve the competitiveness of enterprises. To meet these requirements, carriers need standardized high-level APIs to abstract networks. When the network traffic model becomes more dynamic, operators begin to face the complexity of th

Therefore, a system capable of automatically associating terminal data based on relevant network information can immediately report any device fault or insert service quality to service providers. Passive monitoring of end-user devices can be successfully supplemented by the active test solution, which continuously veri

initializing and installing the server.9. The role of IIS logging is mentioned above, but the most important role of logging is to monitor specific events for you, which may cause problems in servers or hosted applications. It is equally important for you to monitor the running time, availability, and performance of the server itself. You can also monitor the SLA of an IIS server, whether it is an internal (company) or external (client)
