server| Solution | data | The concept of data synchronous replication
Replication is the technique of copying a set of data from one data source to multiple data sources, and is an effective way to publish a single piece of data to multiple storage sites. With replication technology, users can publish a single piece of data to multiple servers so that different server users can share the data within permission. Replication technology ensures data consistency by ensuring that data is automat

A porttype represents an interface (a collection of operations supported by the Web service), and each WEB service can have multiple interfaces, all of which are represented using porttype. Each operation also contains the input and output portions.· How part--Contains binding elementsThe binding element binds porttype to a specific communication protocol (such as the SOAP Protocol on HTTP)· Where part--made up of service elementsIt describes the porttype,binding and

Virtual Private Network VPN
Virtual Private network VPN is "virtual private network". Defined as a temporary, secure connection through a public network (usually the Internet), a secure, stable tunnel through a chaotic public network. VPN through virtual private network can help remote users, branch, partners and distributors, such as the establishment of internal trusted security links to ensure the safe transmission of data, so that
Plugins are programs that will automatically execute as the Internet Explorer starts, depending on where the plugin is loaded in the browser, it can be divided into toolbars (Toolbar), browser Assist (BHO), search hooks (URL searchhook), and download ActiveX (ActiveX).
Because plug-ins by different distributors for plug-in development and distribution, its technical level is mixed, the plug-in program is likely to conflict with other running programs

After in-depth communication with system users, the system analyst is clear about system scope, system function and external related things. The identification of the activity needs to be repeated several times, by asking the user to identify the active person. For example: WHO/what is interested in the results of system operation, will change the data in the system, get information

As mentioned earlier,Nginx does not derive a process or thread for each connection, but rather the worker process accepts a new request by listening on a shared socket and uses an efficient loop to handle thousands of connections. Nginx does not use arbitrators or distributors to distribute connections
