Azure content delivery network Service
What is Azure content delivery network?
A dispersed network of servers that can effectively provide consumers with web material is known as a content delivery network. To reduce latency, a content delivery network caches material on edge servers located in point of presence (POP) sites near end users.
By storing material at carefully positioned physical nodes throughout the globe, Azure material Delivery Network gives developers a worldwide option for quickly delivering high-bandwidth content to users. With the help of content delivery network POPs and other network optimisations, Azure Content Delivery Network can also speed up dynamic content that cannot be stored. Route optimisation to get around the Border Gateway Protocol (BGP), for instance.
The following are some advantages of delivering website assets with Azure Content Delivery Network:
- Enhanced end-user speed and experience, particularly in apps where users must make several round-trip requests in order to load information.
- Large scaling to better manage high loads that occur suddenly, like when a product launch event begins.
- In order to reduce bandwidth transmitted to the origin server, user requests and content are distributed and served directly from edge servers.
How it works?
How does Azure Content Delivery network works
Alice, the user, uses a URL with a unique domain name, such , to request a file, also known as an asset.AzureEdge.net. This name may be a custom domain or an endpoint hostname. The best-performing POP location typically the one nearest to the user geographically is where the DNS directs the request.
The POP asks the origin server for the file if none of the edge servers have it in their cache. Any publicly available web server, such as an Azure Web App, Azure Cloud Service, or Azure Storage account, can act as the origin server.
The file is sent back to an edge server in the POP by the origin server.
The file is cached by an edge server in the POP and sent back to Alice, the original requestor. Until the time to live (TTL) indicated by its HTTP headers passes, the file is kept in the POP cache on the edge server. The default TTL is seven days if no TTL was specified by the origin server.
The same URL that Alice used can subsequently be used by other users to request the same file, which will take them to the same POP.
The POP edge server returns the file straight from the cache if the file’s TTL hasn’t passed. A quicker and more responsive user experience is the outcome of this approach.
Conditions
You need to have at least one Azure subscription in order to use Azure Content Delivery Network.
A content delivery network profile, which is a grouping of content delivery network endpoints, must also be created. Each content delivery network endpoint has a unique configuration that users can alter to suit their needs for access and content delivery behaviour. You can utilise different profiles to arrange your content delivery network endpoints according to web application, internet domain, or other criteria.
You must construct different content delivery network profiles if you wish to employ a mix of pricing tiers since Azure Content Delivery Network pricing is applied at the content delivery network profile level.
Restrictions
The following resources are subject to default limits for each Azure subscription:
- How many profiles of content delivery networks were produced.
- How many endpoints are generated in a network profile for content delivery.
- The quantity of endpoints that are assigned to custom domains.
Summary
Boost scalability and speed for the best possible user experience.
When distributing or encrypting firmware updates, gaming software, and IoT endpoints, save bandwidth and enhance responsiveness. Shorten the time it takes for streaming media, mobile apps, and webpages to load.
Reduce latency and boost performance for high-bandwidth content by distributing user requests and serving material straight from edge servers. Deliver better online experiences by bringing the material closer to the users and reducing traffic to the origin location.
Use a platform that adapts to changes in traffic to scale quickly and without interruption. With a dispersed, worldwide presence, a content delivery network can manage severe loads and abrupt traffic spikes, such during big product launches or international athletic events, without incurring additional infrastructure expenses or capacity issues. Globally dispersed points of presence (PoPs) guarantee quick content distribution while shielding the source from excessive traffic.
Use features like DDoS mitigation and custom domain HTTPS to maximise security. To defend the origin server against hostile attacks, position edge servers in the front line. Use geo-filtering to make sure the content is only seen in designated areas, and set advanced rules to reject requests or verify users.
Create and automate worldwide applications quickly while maintaining security, dependability, and performance. Use a single API to manage all of the Content Delivery Network endpoints that have been deployed by each provider. Azure APIs provide you the freedom to optimise features for performance and availability.
