Load balancers, proxies, and web security gateways play important roles in ensuring the reliability and security of web applications and user access to external web content. In this video, learn the basic functioning of each of these three devices and the role they play in enterprise security.
- [Instructor] Some devices play a hybrid role,…serving as both important network devices…and significant security controls.…In this video, we look at three of these hybrid devices:…load balancers, proxies, and web security gateways.…Basic web server configurations look something like this,…assigning an IP address to a web server…located on a DMZ network.…Network administrators then create a DNS entry…that ties the registered domain name for the server,…let's say www.myserver.com,…to the IP address of that server.…
Then, when users type myserver.com into their web browser,…they connect to that web server located in the DMZ.…This works well as long as the web server can keep up…with those requests from users.…Eventually, if the website grows, the demand for the content…will exceed the capacity of the server.…Administrators might respond by making the server bigger,…but eventually the demand may grow again,…requiring a bigger and bigger server.…This approach is not scalable, because eventually,…administrators won't be able to purchase a bigger server…
