A Strategy for Minimizing Live Streaming Costs with Red5 Pro
Anyone planning to use public cloud services to support live streaming at massive scales on the Red5 Pro platform has reason to expect the optimum solution will be one that’s least expensive.
How can this be?
Simple. As we all learned from economics 101, once we’ve found the solution we’re looking for, what we pay depends on our freedom to shop.
Ever more OTT video service providers are discovering the best way to stream live content to vast audiences at sub-second latencies is to create their own CDN infrastructures using Red5 Pro’s streaming platform. But what might not be so well understood is that if you’re relying on providers of public cloud resources for some or all of the infrastructure you need to instantiate Red5 Pro, you can mix and match whatever combination of those resources works best for you to reach all locations with fail-safe redundancy.
In other words, you have freedom to shop.
Of course, you can choose to implement Red5 Pro with a single supplier of cloud compute resources. If market-leading brand recognition is an important criterion, Red5 Pro has made it easy to work with AWS, Microsoft Azure or Google Cloud Platform utilizing Custom Cloud Controllers developed to translate the commands generated by Red5 Pro’s Stream Manager for interactions with their API calls.
But Stream Manager, the software set that orchestrates operations across all Red5 Pro CDN node clusters, can just as easily be used to manage those clusters in a cross-cloud configuration that may or may not involve any of the big three. Such possibilities make all the sense in the world considering that the normalization of public cloud computing as a routine aspect of doing business in today’s economy has triggered an outpouring of cloud computing providers worldwide.
Here 11 providers are highlighted in addition to the big three as examples of the many infrastructure-as-a-service (IaaS) offerings that can be used with Red5 Pro. Some of these cloud services operate at global, others at regional scales using either container- or hypervisor-based versions of virtualization technology or, more often, both.
Red5 Pro is enabling its customers to take advantage of this cornucopia of options through a single Cloud Controller that interacts with HashiCorp’s Terraform open-source multi-cloud toolset. Terraform translates IaaS resources into a high-level configuration syntax that allows APIs to be abstracted for access through a Terraform Cloud API specific to each provider.
Red5 Pro’s Stream Manager, communicating through the platform’s Terraform Cloud Controller, leverages each Terraform configured provider’s APIs to manage Red5 Pro clusters running on any combination of affiliated IaaS platforms. These clusters, consisting of Origin, Relay and Edge Nodes, enable live streaming at 200-400 ms. speeds end-to-end with scalability to millions of users anywhere in the world using any of five transport modes: WebRTC (Real-Time Communications); SRT (Secure Reliable Transport); RTSP (Real-Time Streaming Protocol); RTMP (Real-Time Messaging Protocol), and MPEG TS (Transport Protocol).
Red5 Pro customers’ flexibility to use whichever Terraform provider platforms they choose is facilitated by mechanisms that mitigate any disparities in approaches to virtualization between a Red5 Pro customer and an IaaS supplier.
In the case of customers accustomed to working with virtual machines running on hypervisors who want to leverage a Docker container-based IaaS provider that utilizes Kubernetes to orchestrate containers, the Red5 Pro Terraform Cloud Controller directly interfaces with the Terraform Kubernetes Provider, which performs the abstractions necessary for conformance with the containerized environment. Likewise, there’s an OpenStack Provider that allows a container-oriented video service provider to work directly with an OpenStack-based IaaS provider.
This sampling of 11 IaaS providers that can be employed to support instantiation of a Red5 Pro-based live streaming CDNs illustrates the flexibility video service providers now have to avoid overspending while creating the most robust means of reaching targeted audiences with backup redundancy wherever they are at ultra-low latency. This is possible because Stream Managers orchestrating individual clusters and sharing the same database are all aware of the state of the whole network.
With holistic management of all resources in the Consolidated Cloud Distribution System (CCDS), Stream Managers are able to perform load balancing and instant reconfiguration of nodes in the event of failures. Using Red5 Pro’s Autoscaling Feature, they are able to control dynamic utilization of CCDS resources, spinning instances up or down whenever and wherever conditions change.
The IaaS providers profiled here have made it simple to quickly discern their potential usefulness in any given implementation of a Red5 Pro CDN. Most of their websites provide access to comprehensive pricing information, the technical details of their platforms, locations of facilities and much else. They all offer aggressive usage-based pricing with flexibility to scale resources as needed.
Taking them alphabetically, here are snapshots of each:
In operation since 2009, China’s answer to AWS has built a cloud compute business recently ranked as the fifth largest in the world accounting for about 4% of the $206.2 billion in estimated revenue generated by the cloud service sector in 2019. Alibaba’s global cloud infrastructure offers IaaS support in 21 regions of 12 countries, including 9 regions in China. The company says it is investing $28 billion over the next three years to expand and upgrade the infrastructure. It is strongly focused on global elasticity with a China-centric perspective, enabling customers to extend the reach of their applications seamlessly across the regional footprints in China and elsewhere utilizing its Elastic Container Instance, various iterations of hypervisor-based virtualization.

The company supports a wide range of virtualization modalities including several hypervisors and container iterations based on Docker and LXC. Everything, including the Tencent Kubernetes Engine, resides in dedicated Tencent Cloud Virtual Machine instances running on its logically isolated CVM private network, which brings a uniform level of robust security, multi-OS Linux and Microsoft management, elasticity and scalability to all environments. Tencent also supports GPU cloud computing in all regions
This Canadian cloud service provider, operating from two large datacenters in Montreal and San Jose, positions itself as an ideal regionally focused choice for a cross-cloud architecture. The company is a strong advocate of OpenStack-based virtualization, which it believes is a better foundation for Kubernetes-based container operations than a bare-metal environment. It has implemented OpenStack’s Magnum API to enable containerized instantiations on its servers.
The New Jersey-based company operates 17 datacenters, including nine in the U.S., four in Europe and one per country in China, Japan, Singapore and Australia. Originally built as a KVM-based platform, Vultr’s cloud compute system has been enhanced to support Kubernetes-managed containers as well.
