DNS load balancing method The RR-DNS (round-robin Domain Name System) takes turns by: In a DNS server,You can configure the same name for multiple IP addresses. When the client queries this name, it will get an address when parsing this name. Therefore, for the same name, different clients will get differentTo achieve

and block occupy about 150 bytes of space. Therefore, if there are million files and each occupies one block, at least MB of memory is required; At present, millions of files are still feasible. When it is extended to billions, it is difficult to achieve the previous hardware level; 2) The number of map tasks is determined by the split. When mapreduce processes a large number of small files, too many map tasks will be generated, and the thread management overhead will be the job time; For

Comparison of advantages and disadvantages of three Load Balancing Methods in Tomcat Cluster

cannot detect it and will not forward the request. The common advantage of R-proxy and mod_jk is that only Apache can be deployed on the public network, saving public IP Address resources. Apache can handle static web pages through settings, so Tomcat can handle dynamic requests such as JSP and servlet. The common disadvantage is that if the front-end Apache proxy server stops running, all cluster services cannot be provided externally. R-proxy and mod_jk can be used to select an optimal effect
