While choosing unified communications for more efficient and productive business processes and growth, the choice betweenon-premise deployment or moving on to cloud delivered service provided by a service provider has always been a bit confusing among users, particularly, business houses and enterprises. And this paradox has been witnessed not only in unified communications, but most of the services like implementing a secure email system to video conferencing solution.
Unified communications offers the most significant support to business communication inaudio video collaboration. Some of the most heard concerns about the cloud managed unified communications are around the reliability and security, other than customised solutions. But with the advanced encryption technology, the cloud-based unified communications services are as secure and impregnable as any system installed on-site.
The hype around cloud computing has taken hold of the unified communications market. For technology vendors, simply attaching the term ‘cloud’ to any service that resides beyond the firewall of the organisation has become the norm. The trick for telecom administrators is cutting through the hype to exactly know what unified communications cloud services have to offer and what is the difference between them and traditional hosted and managed unified communications services.
Cloud-based unified communications provide services that hosted and managed services never have. Cloud-based unified communications offerscorporate organisations elasticity and agility. Companies have the ability to scale their deployments up and down and add new features and functionality whenever required.
With traditional hosted PBX offerings, service providers build the required networking and computing infrastructure within their own data centers and sell access to this infrastructure to their customers as per their requirement. The carrier owns and has the licenses for both the software and hardware and takes care of the maintenance and support of these systems. Typically, the carrier has sole discretion over whether it applies software updates and new features to the hosted service.
Managed service providers usually manage unified communications infrastructure installed within an enterprise, providing remote or on-site support.
Here are some features that show how unified communications as a service (UCaaS) is better thanon-site installation, and what are the advantages and disadvantages thereof:
Multi-Tenacy vs Single-Tenacy
Organisations providing unified communications as a service build, run and manage a complex infrastructure that includes licensing of software, provisioning the equipment, putting in place a customer service team, etc. Among many available technologies and solutions in unified communications, an expert service provider makes the most appropriate selection of equipment and technologiesfor a client keeping in mind the unique requirements of a business. Sometimes, resources are shared between various clients to keep the operational costs low. This is called a multi-tenacy model. One disadvantage of multi-tenacy model is that it doesn’t allow for integration of other systems already in place in your organisation.
Opposed to this, single-tenacy model works well with organisations who opt for cloud-based unified communications but also want complete integration of other proprietary systems or tools the company has on premise.
With on-premise deployment of unified communications system, one has to buy a new license for every new user added to the system. So, whenever there is a new employee in the organisation, IT and other teams have to coordinate to provision user rights for a new person joining in. This takes up extra cost and time. With on-cloud unified communicationsservice, that provisioning is done by the service provider for every new user. The system provides good flexibility to adapt to the requirements. Whenever the organisation wants to scale up or down the system, based on the changing number of people using the unified communications service, the scaling up or down can easily be done by the service provider.
