===Content delivery network===

A [[content delivery network]] (CDN) is a network of distributed servers that deliver pages and other [[web content]] to a user, based on the geographic locations of the user, the origin of the web page and the content delivery server.

{{Main|Content delivery network}}

A content delivery network (CDN) is a network of distributed servers that deliver pages and other [[web content]] to a user, based on the geographic locations of the user, the origin of the web page and the content delivery server.

CDNs were introduced in the late 1990s as a way to speed up the delivery of static content, such as HTML pages, images and videos. By replicating content on multiple servers around the world and delivering it to users based on their ___location, CDNs can significantly improve the speed and availability of a website or application. When a user requests a piece of content, the CDN will check to see if it has a copy of the content in its cache. If it does, the CDN will deliver the content to the user from the cache.<ref name=":0">{{cite web|url=https://people.cs.umass.edu/~ramesh/Site/PUBLICATIONS_files/DMPPSW02.pdf|title=Globally Distributed Content Delivery, by J.

===Cloud storage gateway===

{{Main|Cloud storage gateway}}

A [[cloud storage gateway, also known as an edge filer,]] is a [[hybrid cloud storage]] device that connects a local network to one or more [[cloud storage service]]s, typically [[object storage]] services such as [[Amazon S3]]. It provides a cache for frequently accessed data, providing high speed local access to frequently accessed data in the cloud storage service. Cloud storage gateways also provide additional benefits such as accessing cloud object storage through traditional file serving protocols as well as continued access to cached data during connectivity outages.<ref name="searchstorage1">{{cite web|url=https://www.techtarget.com/searchstorage/definition/cloud-storage-gateway|title=Definition: cloud storage gateway|work=SearchStorage|date=July 2014}}</ref><!--[[User:Kvng/RTH]]-->
