Understanding every organization has unique requirements and almost more importantly each IT leader feels differently on how to manage their system, which emphasizes the need for a customized solution, not one size fits all. Knowing the advantages and disadvantages for each premise, hosted and hybrid deployment options is one way to begin the analysis of which of solution is best for your needs as well as taking the Deployment Quiz.   


The 3 Deployment Options: Premise, Hosted, or Hybrid

Deployment Infrastructure Quiz


A premise based architecture, aka on-premise infrastructure, is the traditional deployment option for both conventional and IP-based systems. In this model servers are acquired, operating systems are installed, additional hardware may be involved, but all components of the system live within the walls of your personal data center. 


  • Environmental Control
  • Physical Security
  • Capital Expenditure (CapEx)
  • Highly Customizable
  • Equipment Ownership
  • Fixed Resources
  • Installation Complexities
  • Maintenance Costs


The hosted or a cloud deployment option is often referred to as a cloud-based system. In a hosted deployment the company's IT department takes a smaller role in both managing the system as well as maintaining equipment and leaves it in the hands of the hosted service provider.  Rather than purchasing, installing and maintaining business phone systems, users of cloud based phone systems and various UC solutions subscribe to a monthly service from that same provider.


  • Monthly Operational Expenditure
  • Lower power consumption
  • Greater capacity for scalability
  • Managed Updates


  • Limited Customization
  • Less Control
  • Security Risks



A hybrid deployment option in a cloud computing environment is an architecture which uses a mix of on-premise infrastructure for resiliency and cloud delivery models for scalability and balances between the two platforms. In this system design both the public and private cloud framework are deployed. These systems can engage independently from each other, with the ability to communicate through an encrypted connection.  This is made possible by using technology that allows for the portability of data and applications, giving you the best of both worlds. 


  • Greater Flexibility
  • Redundancy
  • Enhanced Security
  • Scalability


  • Dependent upon the configuration
  • Existing infrastructure must be up to date before transformation


Finding the deployment option that best fits your organization's business communications solution is imperative. The delivery of voice, video, and data in the workplace is the backbone of business communications which directly impacts the success of your company. The phone system you choose for your solution should also be flexible in supporting any option, like Avaya IP Office for example. IP Office is scalable enough to grow with your business whether your needs are to go from on-premise to cloud or hybrid. When done properly, your customized solution should meet budgetary demands and the needs of the IT staff and management.
