Limelight EdgeFunctions is a serverless compute platform that automatically makes your code available to many edge locations around the world, executes at the network edge close to your users to ensure the lowest latency, and scales to meet demand. EdgeFunctions is ideal for customers needing to implement streaming video and content delivery use cases such as personalized streaming, access control, dynamic ad insertion, A/B testing, image manipulation and more. It is tightly integrated with one of the world’s highest-performing video and Content Delivery Networks (CDNs). EdgeFunctions gives developers tools to boost performance, customize workflows and scale rapidly while only paying for resources used.
With EdgeFunctions, developers are able to run their code without having to worry about the underlying infrastructure, simplifying development and reducing time to production. It enables developers to concentrate on what they are good at: coding!
It’s fast and easy to create new applications, add new features and improve user experience. The ability to execute functions at the network edge close to your users provides opportunities for flexible, highly responsive experiences.
An API-first approach to serverless computing with support for Node.js, Python and Go means developers can focus on innovation and integration without the complexity of managing underlying infrastructure.
Enhance your ability to control and customize your streaming video and content delivery workflows by moving functions to the network edge, providing the control you need with fast response time.
Delight your users by moving compute to the edges and executing at the closest location for each user session, providing significantly lower average latency compared to centralized cloud serverless compute. The farther the user is from a centralized cloud location, the bigger the benefit.
Limelight automatically makes your code available to many edge locations around the world for global coverage and snappy response wherever your application needs it. Plus, EdgeFunctions features elastic resource allocation so capacity automatically scales as demand changes.
Fast access, compute and delivery all contribute to the exceptional performance of Limelight EdgeFunctions. With peering connections to over 1,000 global last-mile providers, each user’s request has fast and efficient transit into and out of the Limelight network, minimizing latency. Limelight further reduces latency by executing serverless compute tasks at the network edge close to the user. Compute resources are distributed in PoPs globally at the network edge, collocated with Limelight’s delivery infrastructure. Results are delivered over the same high-performance delivery network that the most-demanding video streaming services trust. And when used to optimize video and content delivery, the ultimate result to the user is high-performance delivery optimized by high-performance serverless compute at the edge.
EdgeFunctions serverless compute is ideal for streaming video and content delivery use cases. Today’s streaming video ecosystems often include in-house and third-party services that enhance the core delivery, and EdgeFunctions is an excellent way to manage those services. Customers can implement their innovative ideas to solve business problems and craft new experiences. Example use cases include:
Deliver video optimized for user’s device, content preferences, location, and other personalization factors.
Authenticate, authorize or block access to video and other content. You can also offer a subset of your library to non-authenticated users to create upsell opportunities.
Maximize revenue with ads targeted by viewer, region profile or other desirable demographics, integrating with advertising ecosystems of your choice.
Deter piracy with uniquely identifiable streams per viewer, integrating with the watermarking technology of your choice
Capture client data for augmentation, normalization or filtering to feed analytics systems.
Improve usability by testing alternative layouts and content to determine which are more appealing to your users.
Optimize and/or customize user experiences with active origin selection.
EdgeFunctions is API-first and supports Node.js, Python and Go. The serverless architecture makes deployment easy and removes concerns about infrastructure and scale. Just upload your code using the Upload API at no cost, and in seconds it is available globally. To run your code, simply embed calls in user sessions using the Invoke API — Limelight executes compute tasks at the network edge close to the user, and automatically scales compute capacity to meet demand. You only pay for resources used, without worrying about infrastructure or paying for overprovisioning.
A ‘Function-as-a-Service’ (FaaS) platform that provides compute resources without a developer needing to worry about the underlying infrastructure
Limelight automatically makes your code available across the network edge
Minimize latency by executing code at the network edge close to the user
REST APIs to upload code and to invoke the functions make integration easy and flexible
EdgeFunctions supports multiple popular programming languages
HMAC authentication requires username and a MAC hash generated with the user's shared key and timestamp
Limelight automatically scales compute capacity as demand changes, handling spikes without costly overprovisioning
Simple metered billing for requests and compute time
Integrated with a high-performance content delivery network featuring private backbone, advanced software and peering with over 1,000 ISPs
Managing infrastructure is a constant challenge and a constant drain on your resources. Even with cloud infrastructure you need to worry about software versioning, compute locations, and the stresses of ensuring peak capacity which often means paying for overprovisioning.
Limelight EdgeFunctions means no more overprovisioning costs, no more worrying about scale and capacity. Just upload your code and Limelight takes care of the rest.
