A service provider (ASP) application of efficient full service data center is largely dependent on the design of a redundant, high-performance infrastructure cabling System. Do you receive an alert when the computer displays a "server is not responding" message? Such experiences often occur even in IT companies with large investment and high staff quality.

Detailed description of mysql redundancy and duplicate indexes, detailed description of mysql redundant Indexes Mysql allows you to create multiple indexes on the same column, whether intentionally or unintentionally. mysql needs to maintain duplicate indexes separately, and the optimizer also needs to consider the query optimization individually, this affects performance. Duplicate indexes refer to the same types of indexes created in the same order

The redundancy configuration mentioned here refers to the configuration of multi-server Load balancer for the following purposes.

RAID (Redundant array of independent disk independent Redundant array) technology was proposed by the University of California, Berkeley, in 1987, initially to combine small, inexpensive disks in place of large expensive disks, while hoping that the disk will fail without damaging access to the data Development of a certain level of data protection technology. RAID is a

According to the actual business needs, many of the data need to be permanently saved, and not with the subsequent changes in the data to affect other data, for example, the e-commerce system of orders, the order includes the price of the goods you bought 100,n days a May fall to 90, then your order price will be 90? How to solve? My answer is: Add the Price field directly in the order table and write the price every time the order record is generated. I think if a field like "price" is too much
