The cloud has had a major impact on broadcast workflows, with media companies moving their infrastructure to the cloud or private data centres in a bid to simplify workflows and reduce costs. Many broadcasters are now looking to a hybrid cloud approach, which leverages a mixed computing storage and services environment that combines on-premises infrastructure (and/or private cloud services) and a public cloud – such as Amazon Web Services (AWS) or Microsoft Azure – with orchestration between these various platforms.
In the IABM’s executive keynote speech at last year’s IBC, the organisation said that over 47 percent of media companies are deploying public cloud services, up from 39 percent in 2018. The question to ask now is: How can your media facility benefit from a hybrid cloud environment?
Maximise storage opportunities, reduce costs and increase value
The hybrid cloud offers broadcasters the ability to meet business objectives quickly while maintaining full control of media archives and costs. It also ensures a low-risk transition into the cloud by moving the operation in line with business needs. Sensitive data and valuable content can be secured on-premises under company control in a safe IT environment with multiple security layers.
Hybrid cloud architecture also reduces the total cost of ownership. CAPEX is lower, as the upfront investment is calculated based on the nominal usage and not for peaks, which allows the broadcaster to keep the investment at the desired level. In 2020, on-premises costs of deep archive management (tape library) will continue to be lower than the public cloud as the download costs from the public cloud are still a key factor when production teams require constant download (either full or partial) from the archive. This is especially true when UHD content is considered.
By using computing storage and services architecture that combines the privacy and security of a private cloud with the scalability of a public cloud, users benefit from orchestration among various platforms and multiple sites. They can store sensitive data and high-value, high-resolution content on-premises, inside a secure IT environment that’s not accessible outside their facility and fully under the control of their IT team, all the while less critical operations can be deployed and run in the cloud. This provides flexibility, as burst or peak demands in business operations can also be quickly deployed and run in the cloud. This means that media companies pay only for the period of time required by the additional business operations. High-cost services such as storage for archiving can benefit from the ability to tailor operations to the business cost criteria.
Using hybrid cloud architecture also means that optimisation and control of bandwidth: latency is improved, as is the prioritisation of ingest and delivery workflows. Low-res data can be accessed from the public cloud from anywhere in the world, at any time providing the same quality of service for end users thanks to public cloud geographical deployments. Media companies can move business processes to the cloud at their own pace, as their business grows. Their business is future-proofed as cloud technology will evolve faster than the technology used on-premises or in a private data centre.
Also because cloud costs evolve over time, the split between the on-premises versus cloud business operations can be reviewed frequently to keep costs under control.
Hybrid cloud allows the transition of certain processes into the cloud with minimum risk as the workflows can move seamlessly without affecting normal operation. This assists the customer with the change management process.
Another key benefit is the capability to test new ideas and deploy new workflows or new solutions outside of the current primary workflows, without affecting normal operation, using the latest cutting-edge cloud technology and only for the duration of the test. If the test is successful, then it can be integrated as part of regular operations. If the test is unsuccessful the project is simply discarded, and the facility has only incurred the cost associated with the time and infrastructure used to carry out the test.
The hybrid cloud allows the integration of updated cloud AI tools for automatic content enrichment. AI tools will improve considerably in the incoming years and executing them from the cloud will guarantee the most up-to-date version is always used.
Cloud is also ideal for content delivery, as many delivery services are currently running in the cloud and customers can securely access content due to the native cloud security mechanisms.
Meeting technology demands now and in the future
To take advantage of hybrid cloud architecture media companies need a dynamic content management solution that transparently manages various tiers across departments, locations or in the cloud. This includes on-premises live storage, nearline storage, deep archive tape libraries or public cloud storage such as AWS S3 or AWS Glacier. This technology should enable media companies to efficiently operate using their chosen current architecture with the capability to evolve as future operational and commercial factors change.
Tedial’s Evolution MAM is built with aSTORM, a dynamic storage management solution that is agnostic to storage tiers (on-premises live storage, nearline storage, deep archive tape libraries or public cloud storage). aSTORM provides the ‘link’ between various storage and hosting scenarios available today and in the future.
Using logical storage groups and rules defined within each group, the technology seamlessly moves, backs up and restores content when and where required. Live content can be kept on online storage for a period of time depending on its genre. The content management solution can immediately archive content to tape while storing it online for a certain period of time depending on the logical storage group. News content can be kept online for 48 hours, while live sport, which might need to be kept for editing throughout a whole week, can be kept in online storage for seven days, for example. Similar rules can be set using a public cloud.
Providing advanced security features in addition to standard IT protections, Tedial Evolution also integrates with cloud-based AI technologies. Although workflows can be deployed on-premises or in cloud, non-critical workflows such as automating metadata tagging with AI would typically be deployed in the cloud, while critical workflows would be deployed on-premises. The advantage of this hybrid cloud integration is that customers keep full control of their critical workflows and operation while benefiting from the latest cutting-edge cloud features, technologies and infrastructures, providing increased value to the production team.
Using Tedial’s HTML5 web-based Evolution MAM, operators from all departments and external partners can access content from anywhere, anytime. For example, teams are able to find more content, browse proxies, download or edit files without going through an archive team, who can now fully focus on their primary work of cataloguing and preserving content, significantly improving efficiency and productivity.
In a typical hybrid cloud solution, users should deploy all workflows needed for normal operations on-premises and deploy additional workflows in the cloud for peak operations, and keep low resolution content and metadata in the cloud and high resolution content on-premises on online storage and in a tape library, to avoid high costs related to downloading content from the cloud. High resolution content can be managed by on-premises delivery workflows, which can ensure QoS of delivery is met. Users can also implement delivery workflows in the cloud to maximise performance and efficiency. Using Tedial’s Evolution MAM with aSTORM, media companies can achieve a secure and successful hybrid cloud approach.
