Join Mike Chapple for an in-depth discussion in this video Load balancers, proxies, and web security gateways, part of CompTIA Security+ Exam Prep (SY0-401): Network Security.
- 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 web site 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 and they'll also be left…
