FASTLY’S CORE VALUES
Based on edge cloud platform, Fastly integrates many useful features into its CDN edge nodes such as Image Optimization, Video On Demand, Streaming, Cloud Security and Load Balancing. Fastly not only helps company deliver and secure their content, but also ensure high availability and reliability. In recent years, many businesses are seeking for digital transformation and gradually moving their infrastructure or services to cloud. Meanwhile, people can do more things through the Internet. For example, patients see the doctor online, people can buy everything from online retailers or e-commerce platforms, traditional media is moving to new media and shifting their content to online platforms. All of these changes give rise to the huge growth of network traffic. In order to provide a better user experience while fetching content from the Internet, edge computing becomes one of the most popular solutions.
MODERN CDN – DELIVER CONTENT FROM CLOUD
In Fastly, all features are built on the Edge Cloud Platform. For legacy CDN, most computing were done in centralized servers which introduced more latency due to the requirement on passing data between servers and POPs. Until edge cloud platform was released, a lot of things can be done in edge node (distributed computing), e.g. image optimization, WAF, load balancing, and this change reduces the frequency of communication between origin and edge node while cache hit rate is high enough. Other than the decrease of latency, it also helps companies reduce the cost of bandwidth.
POPs are driven by SSD, businesses can store more data in cache for fewer trips to origin, further increase the cache hit rate for lower page load time and renew cache by Instant Purge or Batch Purge to ensure the user is always served with the latest content. Fastly also supports instant log analysis and integration with third-party analysis tools which allows businesses to use their familiar tool for quickly delivering the data-driven business decision. For developer, they are able to leverage APIs exposed from Fastly’s platform and integrate them into existing CI/CD flow. In addition, they do not need to stop the application while updating platform settings and what the most impressive thing is configuration update only needs up to 5 secs for taking effect which greatly improves the efficiency of maintenance and development of website or applications deployed on the edge cloud platform.
Fastly also optimizes the handling of common contents. For example, transforming images at edge node eliminates the latency by reducing the number of requests back to origin. Moreover, image optimization reduces not only the cost of bandwidth but also the requirement of storage in origin. To summarize, with Fastly’s image optimization, website or application is able to provide a better experience of image loading and achieve huge cost savings. More than image, Fastly also emphasizes on the rapid delivery of video and high quality of live streaming. With 97% or more cache hit rate, it greatly reduces the time to get the first frame.
Given everything is kept in the cloud, cloud security is also a key factor for edge cloud platforms. DDoS protection, Web Application Firewall(WAF), Threat Detection and TLS encryption are all available. Other than security, load balancing is also supported at the edge node to ensure the server will not overload while handling a large number of incoming requests which may cause service outage. With all of these amazing features, Fastly’s edge cloud platform especially empowers the business having rising customer expectation, e.g. Amazon, Shopify or Youtube etc. to ensure their website and service can be loaded smoothly with heavy traffic.
