Service continuity is the guarantee that your video is available to subscribers, all the time. It's a prerequisite for video streaming and broadcast, especially for live content. However, sometimes, things happen.
Certain content for major global events, like international sports competitions, or even the news, can attract a significant number of simultaneous viewers. Whether streamed live, with catch-up TV, or on-demand, it can create peaks in traffic. If your system is overloaded, or if there is a power outage or a hardware failure, outages can occur. Viewers are unaware of the pressure on video streaming systems and expect the experience to be flawless. And so do advertisers.
Let’s say you’re broadcasting or streaming video for a major event, with millions of viewers watching. Suddenly the feed goes completely black. A worst-case scenario that you absolutely never want to experience. A service failure during a live event, whether it’s delivered via broadcast or OTT, could be disastrous for your reputation. That’s when being able to maintain your channel with 100% service up-time is most critical.
So, what happens after a service glitch or failure? There are troubleshooting, video service recovery efforts, and the implications of receiving calls from unhappy subscribers. From a management angle, it can be a whirlwind that you have to financially absorb and resolve. It can be even harder if the outage or problems persist.
No one wants to be caught in that situation. In times of limited travel options or constrained global logistics, spares and services could be harder to come by. Your service failure that would normally last only minutes, may turn into days, or weeks. By implementing a recovery strategy for your video streaming or broadcast service, you can effectively avoid the worst-case failure scenarios.
Service Continuity Solutions
Service continuity solutions are designed to help you avoid service failures. Here are a few options when it comes to ensuring that your services are always running.
Replicate hardware: One video recovery strategy is to fully replicate your equipment for the on-air service. You would need to recreate your entire infrastructure with a second set of hardware. That includes playout servers, storage, receivers, decoders, transcoders, channel modulators, channel processors, origin systems and channel signals. Duplicating your hardware infrastructure does give you a redundant system, but it may have additional implications regarding cost, management, and maintenance.
Replicate your on-premises configuration in the cloud: A more modern and flexible strategy is using the cloud. You can replicate some or all of your services in the cloud and on top of any existing video SaaS. Your video recovery service can also be an intelligent complement to any existing on-premises infrastructure. Your service continuity provider, like Harmonic, accompanies you to define the end-to-end design, configuration and set up to take the guesswork out of securing your services. There are two main contexts for service continuity and video recovery in the cloud: 1) To secure an event. In this case, the service is activated just before the event, and then after, it’s released. You can use this model for one, or even multiple channels at a time. In this context, the on-air time might only be for a few hours or days. 2) To secure a complete infrastructure. In this context, you can have all or even just a set of premium channels running 24/7 with a backup in the wings. The redundant version of the service is only activated as needed. The video recovery service can also be activated for testing or service adjustment. This redundant recovery service can run for days, weeks or even months, depending on the need.
Harmonic’s VOS® Cloud-Native software, for on-premise configurations, and VOS®360 platforms are examples of products that use cloud-based recovery services with intelligent and powerful workflows. With these or similar solutions, you get the most reliable service continuity and only pay for the time that the service actually runs.
Key benefits of recovery services in the cloud
Creating a duplicate hardware infrastructure requires a significant investment, which is not always the most economic option. A duplicate infrastructure must be constantly maintained, updated, and monitored. It may be a more familiar option since you know the systems and vendors. Although, if you do choose to replicate your infrastructure for service continuity, just remember that you would also have to replace the system components every three to five years. And, that would increase costs even further. Or, in some cases, it may create additional risks for downtime, if ever your machines are offline.
With advances in service recovery today, cloud-based solutions now offer the same level of high-availability as the traditional hardware solutions.
Pay-per-use: A recovery service in the cloud is based on a pay-per-use model. The recovery service in the cloud business model makes service continuity affordable for everyone, from large broadcasters to small TV providers. It’s hard to justify the cost of maintenance, power, space, and human resources that a hardware-based solution requires when you have an option that is just as efficient. And it may even offer more advantages for your business.
Total coverage worldwide: The recovery service is linked to all of your TV sources. You can use the video recovery service on-demand for tests, for pop-up channels, premium channels, or for whichever channel you want. You can provide the highest availability to all your subscribers around the world, and they'll appreciate it.
Simplicity: A fully managed SaaS recovery service in the cloud lets you avoid the complexities and costs associated with installing hardware or having to manage and operate.
Essential features in a recovery service
Committed activation time: Take committed activation time seriously. When a service failure occurs during a live event, time is of the essence. Video recovery solutions need to provide you with additional resources that can be activated in seconds.
Reliability: Reliability is also critical. Ensure that your video recovery service is ready for any event by testing it, periodically. This is also known as performing fire drills. For example, with Harmonic’s VOS360 platforms, you can schedule testing on a regular basis. Your service is consistently and reliably tested, and at the fraction of the cost compared to hardware installations. The solution should also let you easily update service recovery definitions, whenever needed. With a recovery service in the cloud, your solution is updated more often, and it’s instant. You get greater protection and more robust security when your solution is up to date.
Scripting: Scripting via API is another essential capability to look for in a recovery service. You can then fine-tune your service configuration however and whenever you want.
Diverse feature sets: Your recovery solution for service continuity should support not only live streaming but also a wide range of features, such as scheduled playout and statmux for broadcast. A truly cloud-native recovery service, based on microservices, is future-proof by design. You get new features fast, and instant upgrades so your solution is always running at its best.
Security: A successful video recovery service hinges on security. Premium live content, especially sports, needs to be protected. Look for a solution that can easily integrate DRM capabilities to ensure that only users that should have access to the content are able to view it.
Service continuity is the key for zero downtime
Regardless of the event or issue, you want to know you can count on continued service. Your goal is to have zero downtime.
A cloud-native recovery solution for service continuity lets you duplicate all your services in the cloud, instantly. You only activate them as needed. It’s cost-effective, scalable and resilient.
