Therefore, enabling them to access the most-available content is essential to meet those requirements with today's Internet business. Scalability, high availability, and performance are critical to the success of any large commercial Web deployment. Typical content delivery environment includes the replicated Web server clusters located at the edge of the network to which the end-users are connected. In such CDN environment, Web content based on user requests are fetched from the origin server and a user is served with the content from the nearby replicated Web server. Thus the users end up communicating with a replicated CDN server close to them and retrieves files from that server. ARA Networks Global Load Balancing Solution provides a complete load balancing solution for large distributed Web infrastructures. Challenges to Content Delivery Network While many enterprises attempt to scale capacity by deploying additional servers and infrastructure at a single location, these centralized architectures are subject to a number of inherent limitations. Centralized Web infrastructures present a single point of failure in the Internet topology - if the site loses connectivity to all or part of the public Internet, it will be inaccessible to end users. Quality of service is also highly sensitive to bandwidth bottlenecks and congestion in the vicinity of the site. Furthermore, users accessing the site from geographically or topologically distant locations may experience large and highly variable delays, which are exacerbated by the large number of round trips that HTTP requires to transfer some Web content. The centralized architecture is also not appropriate for international companies that must serve localized content to users in different parts of the world. The SmartDNS SmartDNS overcomes these problems by distributing Web traffic among a collection of servers deployed in multiple geographic locations. By serving content from several different points in the Internet topology, SmartDNS alleviates the impact of network bandwidth bottlenecks and provides robustness in case of local server or network failures at particular server sites. Users can be directed to the nearest or least loaded server site at the time of the request, minimizing the likelihood of long download delays and service disruptions. Key Benefits SmartDNS offers exceptional benefits for both commercial and large enterprise CDNs by providing: Faster and higher-quality delivery of content to end users Optimized use of network by directing requests based on factors such as system load and network delay Lower costs of installation and management of another device per CDN POP Highly scalable CDN deployment Increased availability of the CDN service and greater quality of service for both content owner and end user As with all ARA Networks solutions, SmartDNS provides a simple and highly scalable approach to solving the complex problem of global request management.
