The broadcast industry is changing. The cloud is perfect for television broadcasting. There are several advantages of cloud-based services – the key benefits are that the service is software-based, so one does not need a physical location to run the operations. As a result, real estate, infrastructure, and manpower cost reduces dramatically. The cloud promises to be more environment-friendly than our current system.
A community cloud links several people or organizations that share a common interest or pursuit (like broadcast engineering, or geology) and provides extra computing power and access to computer programs pursuant to that field of endeavor. The private cloud is run for the benefit of a single organization. Public clouds make certain services and programs available for public use.
In general, the operation costs are highest for private clouds (because only one organization is picking up the tab); community clouds operate more inexpensively (because expenses are paid by an entire type of community), and cheapest with public clouds because anyone can subscribe. You will not be subscribing to a hybrid cloud, per se; hybrid clouds are more of an agreement by cloud providers with other cloud providers to share resources. This type of joint operation agreement can be used to counter network problems of crashing due to an otherwise unmanageable spike in computing usage in a single cloud (this type of data surge is called a cloud burst).
Migrating broadcasting to the cloud is a natural transition. Lot of companies are beginning to trust the cloud for more applications. The cloud can offer on-demand services, which you do not pay for if you are not using them.
There are several advantages of cloud-based services – the key benefits are that the service is software-based, so one does not need a physical location to run the operations. The technology also makes a strong case for pop-up channels, basically allowing broadcasters the opportunity to experiment with their channels without the fear of steep costs.
Broadcasters need to face realty; the wave of the future is here. One thing is for certain – it is time to take a ride in the clouds.
Cloud Broadcast Security
Security is an exercise in risk management, not absolute truths and guarantees. Infrastructures and networks, as secure as they can possibly be, do rely on their clients making their software and access to their services secure. Risk management should be conducted by broadcasters to assess users' access to the system.
Basic Security – Access, Audit, and Asset Security
Your cloud provider should offer a vast array of identity and access management controls that determine who, what, and when a resource can operate or be operated on.
Log everything. Storage is cheap in the cloud, so do not be afraid to be highly verbose in tracking every action performed across your cloud infrastructure and applications.
Encrypt every asset with a unique key backed up by a secure key management implementation.
Cloud security limits itspoints of access with firewalls, advanced monitoring systems using load balancer in the server, traffic is constantly monitored for distributed denial of service attacks, brute force attacks, man-in-the-middle attacks, IP spoofing, port scanning and IP sniffing by other users, and denial port forwarding. Management uses SSH (secure socket shell) protocol that provides administrators with a secure way to access a remote computer. SSH also refers to the suite of utilities that implement the protocol. Secure shell provides strong authentication and secure encrypted data, public-key authentication, and provides audit trails of who has logged-in, and advanced levels of security (Wireshark, etc.) to protect your system from unscrupulous malicious attackers.
