sent by the system administrator, and making high-level VM instance scheduling decisions. It also processes service level agreements and maintains system and user-related metadata. A cloud controller is composed of a group of services used to process user requests, verify and maintain systems, user metadata (Virtual Machine images and SSH key equivalence ), it can also manage and monitor the running of Virtual Machine instances. These services are configured and managed by the enterprise servic

corresponding log file can be used by new transactions. Note that this space reuse or truncation does not automatically reduce the physical size of the log file. If you need to reduce the space, you must use commands such as dbcc shrinkfile/DATABASE. The process of reusing a log space is called truncation. In simple mode, this process is called auto-truncate ). In this mode, logs usually do not need to be managed, but for a single large transaction, log files may grow very fast. In this case, i

Safety Summary Protecting the customer and ASP's data from malicious attacks (intentional or unintentional) is the entire content of security management. A clear understanding of what security management is and how the ASP and its customers can take it is critical, including what security policies are and what level of security needs to be achieved. You need to determine the SLA itself and the level of security it provides, and you need to take approp

log backup, every 3 months a full backup, every 15 minutes a log backup, when the disaster occurs, only through full backup and log backup to recover data, so although no data loss, But because the recovery of data took two days, resulting in 2 days of the banking system is not available, so the loss of a large number of customers. Another example is a domestic online video web site, using SQL Server as a backend relational database, the front-end uses no-sql, regularly no-sql data into the rel

itself, and the data synchronization method uses MySQL replication technology. MySQL replication is a log copy process, during the replication process one server acts as the primary server, while one or more other servers act as slave servers, simply to pull binary log files from the server to the master server, The log file is then parsed into the appropriate SQL to re-perform the operation of the master server from the server, in this way to ensure the consistency of the data.MySQL replicatio

the processing of extensible flag languages. On a Web page, objects that organize pages (or documents) are organized in a tree structure that represents the standard model for objects in a document called the DOM.The Document Object model dates back to the late 1990 's "browser Wars" between Microsoft and Netscape, which gave the browser powerful features in order to make life and death in JavaScript and JScript. Microsoft has added a number of proprietary things to Web technology, including VB

browsers with JavaScript. In 1997, in coordination with ECMA (European Computer Manufacturers Association), a working group composed of Netscape, Sun, Microsoft and Borland established a unified standard: ECMA-262. Because JavaScript is compatible with the ECMA standard, it is also known as ECMAScript. Juery jquery is a cross-browser JavaScript library that simplifies the operation between HTML and JavaScript. The first version was released by John Ressig (John resig) on the BarCamp

cannot be provided by cell-based transmission. In addition, TMX 880 is designed based on the connection-oriented structure to provide high service quality, meet SLA business requirements, and achieve more comprehensive control and faster fault recovery. All of this is based on the unique vswitch hardware and strictly guaranteed QoS of TMX 880. Finally, TMX 880 is managed by Navis, allowing TMX 880 to be seamlessly integrated into existing customer ne

forward decision. Group replication is required under 1 + 1 protection. CPU intervention should be completely avoided, or the lowest possible level should be maintained. This poses a challenge to the design of data paths. OAM Like protection, OAM is another feature that traditional L2 exchange ignores. From the operator's perspective, this is a required feature. CFM and PM are required for both PW and LSP levels to support APS and ensure compliance with SLA
