Notes de l'éditeur
- The Akamai Intelligent Platform is the leading cloud platform for delivering secure, high-performing user experiences to any device, anywhere. It is a network of over 120,000 servers equipped with proprietary software and deployed in over 75 countries. It relies on applied mathematics and algorithms to help solve congestion and vulnerability problems on the Internet. These servers monitor the Internet in real time - gathering information about traffic, congestion, and trouble spots. Akamai uses this intelligence to optimize routes and replicate data dynamically to deliver content and applications more quickly, reliably, and securely. The Akamai Intelligent Platform can: identify, absorb, and block security threats. provide instant device-level detection and optimization. make decisions based on comprehensive knowledge of network conditions. present unprecedented business and technical insights.
- The globally-distributed Akamai Intelligent Platform continuously pulls and caches fresh content onto servers that are closer to the end user. Akamai’s intelligent dynamic mapping system directs user requests for dynamic content to an optimal Akamai Edge Server. Through route optimization the fastest and most reliable path back to a customer’s data center is identified to retrieve dynamic/interactive content. Trips to the origin server to refresh and retrieve content are optimized via the use of persistent connections, thereby reducing connection setup and teardown latency. Additional connection optimization techniques tune the parameters that govern server-to-server connections, as well as reduce the number of long-haul round trips required to retrieve content embedded in the site.
- Load testing provides insight into site performance, which is closely tied to conversion, engagement, and end user satisfaction Load testing also provides means for accurate evaluation of Dos/DDoS impact
- Artificial load is necessary to simulate peak load conditions
- Evaluate origin infrastructure by stress testing directly against the origin, bypassing CDN and excluding 3rd Party content/services
- The growing requirements of delivering dynamic transactions and interactive content must be matched with an increased ability to scale under high traffic load and perform reliably to meet increased consumer demand. Organizations competing for customers measure their success based not on seconds, but on milliseconds. Research has shown that users will visit a website less often if it is slower than a close competitor by more than 250 milliseconds. The difference between a two second load time and a one second load time can mean the difference between a user conversion, and a lost opportunity. In short, organizations seeking the maximum speed and offload must continue to further refine and optimize website performance.
- With Akamai, fewer unique machines connect to your origin server directly and fewer requests are served by your origin.
