Using the following advice can help further with reducing server load: With support for all HTTP methods, including GET, PUT, and POST, CloudFront can speed up your entire website. For parts that are not cached locally, such as newly updated content or specific dynamic requests, CloudFront obtains them from your origin server through a fast and optimized path due to persistent connections on the global network privately managed by AWS. Parts of your website (such as HTML, images, style sheets, and JavaScript files) are served by cached copies stored in CloudFront edge locations and regional edge caches. Reducing server load with Amazon CloudFront CDNĪmazon CloudFront has a global network of edge locations and intelligent software that can deliver content to users around the world from the locations closest to users or with the best performance. With such capabilities, caching hit potential increases to 70%–90%, or more. More advanced CDNs, like Amazon CloudFront, can also cache dynamically generated content (e.g., API calls, ads that are computed on the fly). This alone can save upwards of 60% of your bandwidth usage. While most CDNs offload a considerable part of all content delivery tasks, the exact amount depends on the CDN’s capabilities and the particulars of your website, application or use case.ĬDN edge servers will be able to cache static resources, including images, CSS stylesheets, and JavaScript files. The main metric to understand for this is the cache hit ratio. Is it possible to offload all content delivery by CDN from my origin server? Given that a typical site can contain up to 80% of static assets, using a CDN can greatly help to offload data from the origin server. Therefore, the round-trip time is greatly reduced, and visitors from far away will not slow down for local users. By storing copies of your website at access points around the world, CDN ensures that visitors receive content from servers that are geographically close to them. CDN is a distributed network consisting of strategically placed edge servers that can quickly deliver web content to users around the world.ĬDN can reduce your server load and speed up your website by caching the static content of your website. If you haven't used a content delivery network, it may be time to consider investing. Reducing origin server load How CDNs reduce your server load Other edge devices can include routers.Ī CDN origin server and edge server work together to bring content to users, as you can see in the picture below: An edge server is an edge device that provides an entry point into the network. The main purpose of the edge server is to store content as close as possible to the requesting client machine and help by reducing latency and shortening page load time. CDN edge servers store content in strategic locations to take the load off of one or more origin servers. Edge servers are usually used as connections between different networks. This increases the load time, which increases the distance between the server and the client machine making the request.Īn edge server is a computer or service that exists at the “edge" of the network. Using an origin server without a CDN means that every request must be returned to the physical location of the origin server, regardless of where in the world it resides. edge serverĪn origin server, sometimes called a CDN origin server, is a computer or service, which is the last point of your network and receives all traffic when you are not using a CDN. The most used origin In the AWS Cloud environment is Amazon S3 bucket, Amazon EC2 instance, AWS Elemental MediaPackage, or Elastic Load Balancer. This term is usually used to identify the webserver from the cache (edge) server of a CDN. An origin server can have for instance the original version of your website files (HTML, CSS, JS files). What is an origin server?Īn origin server (origin) is a computer or service where content is stored or computed and is designed to listen and respond to incoming requests. If you want to know what an origin server is, the difference between edge and origin servers, or how to reduce the load on the origin server, read more below. When talking about Content Delivery Network (CDN) you will nearly always see some reference to an origin or origin server.
