Requirements for Content Delivery Network(CDN)

4.1 Functional Requirements for Content Delivery Network(CDN)

• Content Distribution:
  • Define how the system will correctly distribute web content material globally. This includes techniques for replication, content material synchronization, and ensuring the present day content is to be had across all CDN nodes.
• Caching:
  • Specify the caching approach for each static and dynamic content material. This involves figuring out what content need to be cached, for how lengthy, and the way the cache eviction policy ought to work.
• Load Balancing:
  • Define the load balancing algorithm to evenly distribute incoming requests across CDN nodes. Consider dynamic load balancing based totally on real-time server conditions.
• Content Purge Mechanism:
  • Describe the mechanism to invalidate or update cached content material. This involves defining the situations under which content material should be purged and how speedy the purge must propagate.

4.2 Non-Functional Requirements for Content Delivery Network(CDN)

• Scalability:
  • Specify how the system will scale horizontally to deal with increased visitors. This could involve automatic scaling based totally on demand or a manual method for including more CDN nodes.
• Redundancy and Reliability:
  • Define the redundancy mechanisms at diverse levels to ensure high availability. This includes techniques for data replication, failover, and backup structures.
• Global Load Balancing:
  • Detail how global load balancing will be performed to calmly distribute traffic across CDN nodes worldwide. Consider the usage of Anycast routing for green load distribution.
• Content Optimization:
  • Specify techniques for Content Delivery Network , consisting of image compression and minification, to enhance the rate of content delivery.
• Mobile Optimization:
  • Describe how the CDN will optimize Content Delivery Network for mobile devicce, considering factors like responsive design and adaptive content material delivery.

In the digital age, where online content material is king, the importance of delivering a seamless and rapid user experience can not be overstated. Content Delivery Networks (CDNs) play a vital role in attaining this aim by distributing content material strategically throughout servers globally. This article will guide you through the process of designing a Content Delivery Network.
