, support URL detection backend server problem detection will be very good help. 4, it is just like the LVS, itself is only a foot bath powder load balancer software; simply from the efficiency of the haproxy more than Nginx has a better load balancing speed, in concurrent processing is better than nginx. 5, Haproxy can read to MySQL load balance of foot bath , the back end of the MySQL node detection and load balancing, but in the back end of the num

project, cost-effective is much higher than F5, commercial first choice! But in general this phase of the relevant talent to keep up with the business, so the purchase of commercial load balance has become the only way. The ability and quantity of talent is also increased, at this time, regardless of the development of customized products for their own, and reduce the cost of open source LVs, has become the first choice, then LVS will become the mainstream. The third stage: The Network Ser

Terms RAIDAn independent redundant disk array is a storage term. to improve performance and reliability, multiple disks are combined, which is a storage unit from the outside. the detailed introduction to RAID is not within the scope of this document; Wikipedia article "RAID" provides better content. Hard RAIDHard RAID is a RAID ("RAID card") implemented in the storage controller ")Through the unique hardware and firmware. the Controller BIOS provides interfaces for managing RAID installation. f

, files are used to store messages such as matching users' e-mail addresses (for example, bob's mail sender is changed to sales@example.org ). For a large number of users, the file will become very huge, thus affecting the system operation efficiency. Postfix can be integrated with a database background (currently only MySQL is supported) to store its configuration information. The database mode is much more powerful than the file mode in terms of scalability. With IBM's open-source copyright li

In addition to revising the article by way of review, there are often some special situations in daily work. When someone changes an article to you, perhaps the other party did not follow the Office software review and revise the way to deal with, but directly in the article made additions and deletions to modify the operation, so if not to see the original manuscript, the article changes what content, not completely see out.

Algosec, RedSeal, and Skybox can also provide charts and Topology views of their networks. In general, RedSeal and Skybox were the most impressive in this test, because they not only have all the basic functions, but also support vulnerability scanning products from multiple vendors. These vulnerability scanning products can rate risks in the ne

I guess there are two reasons: Youdao dictionary has a local dictionary, while Bing dictionary is more dependent on Internet. The server of youdao dictionary is in China and Bing is abroad.

mechanism. Later, with new features being introduced, the standard slowly evolved into today's SOAP protocol. The XML-RPC agreement is a registered patent project. XML-RPC sends an HTTP request to a server that has this protocol installed. The client that makes the request is generally the software that requires a call to the remote system. simple comparison of three kinds of schemes XML-RPC has slowly bee

Simple comparison between the compression software gzip and xz Due to the need to handle disk alarms, logs are compressed. In this compression, gzip and xz software are used respectively to compress the text. The compression results are very surprising. The objects in the delimiter format are smaller. First, let's briefly introduce gzip and xz: Gzip: GZIP was

the limited disk space, we use the 9 parameter to compress, using the highest compression ratio per compression, using the fame as follows: Gzip:gzip-9-C source_filename > source_filename.gz Xz:xz-9-C source_filename > Source_filename.xz The final test results are as follows: You can see the source file iqas-2015-07-28 size of 35G, after gzip compression, the final file is 4.6G size, compression ratio of about 1:8, this is a good result, but then look a

Comparison and evaluation of two software of protel99 and Protel99se The difference between protel99 and Protel99se is the kernel version. Protel99 is a transitional version with an internal version of 3.0, or Protel98, that is encapsulated in an Access database and integrated into a DDB file. The core of the PROTEL99SE is 4.0. SP6 is the final version, relatively perfect. Note that Protel99 cannot open
