The Application Programming Interface is a set of functions provided for the CDN. It allows simple and standardised interoperability between your web applications and the OVH CDN. Discover the OVH API
A distributed denial of service attack is a common method of making a web application unavailable by saturating it with requests. The CDN PoP network can absorb attacks locally with reduced risk.
Backends are the actual hosting services of your web applications. These sources will be used by the PoP for the cache.
When your data quota managed by the CDN is completely consumed, the caching functionality is automatically disabled. There is therefore no loss of service, it simple returns to the previous performance of your old system.
Each PoP has its own local cache. The content can be requested by all users of your site routed to this point. The content will be refreshed automatically by the value declared in the TTL.
The "Content Delivery Network" is a caching system for static web content within the PoP network.
Static content of a web page means all components which are not subject to dynamic updates. Generally it includes images, videos, static html, audio...
You get tools in your manager which enable you to monitor the traffic saved by your backends. This traffic credit is calculated for CDN usage and must be paid in advance.
A domain is linked to the CDN when the "A" record points to the IP Anycast provided on subscription to CDN service. This change must be made in the customer account of your domain provider.
A web application pointing to an IP Anycast routed in a specific manner. When a user requests a page, the request is automatically directed to the nearest PoP.
A dynamic page is generated specifically for a user by the web application on receiving the request.
A static page is a generic page that is the same for all users of the web application. The data is requested without customisation.
The "Points of Presence" represent the local caches based in France and North America. Each PoP has its own cache, so it can deliver content locally to your users.
Configuration rules allow you to manage the caching and the TTL of your web applications. They are available via your Control Panel or the OVH API.
Search engine optimisation (SEO) can improve the search engine ranking of your websites. The search engines give a better ranking according to you website's performance, which thus improves visibility for your business.
The search engine results page is the page returned by the search engines, listing all pages deemed relevant to the keywords entered.
The conversion rate is the ratio between the number of visits and the number of purchases on a website. This rate can be improved by various parameters such as ease of use (site fluidity, fast loading, availability).
Page loading time
The time needed to provide the user with all the content on a web page.
The time needed for a hosting system to deal with a user's request and send the requested content.
The duration of time between sending the request and beginning to load the web page.
Time To Live is a parameter which enables you to define the time that data is retained in the cache of a PoP.
