merge, you must first define the merge goals for your merged teams and customers, and for the business owners of the user database. These goals are different depending on how you merge: Merging on a virtual machine, piling up a SQL Server environment, and using a storage area network (SAN), and so on.
It is critical that the merge team discuss the actual service level agreement (SLA) with the customer beforehand. These SLAs provide more than just ex

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

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

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
