CPaaS vs on-premises deployment: what is below the water level? Greg Sikora, Head of Presales EMEA, Telestax RestcommONE is Telestax's CPaaS enabling technology. It provides REST APIs and a visual design tool with drag­and-drop programming capabilities for building real­time messaging, voice and video applications and services. The platform supports cloud, on­premises and hybrid deployment configurations. I'm going to share the experience of the real difference between cloud and on-premises deployment.

15. Rationale for CEO
• Expertise - Top talent comes with top costs, and niche skills may be very expensive to attract and
retain. Cloud service providers specialize in an offering, and staff it with the necessary expertise.
• Support & Monitoring - Monitoring systems can run 24x7, but keeping staff around the clock can be
very expensive
• SLA - Choosing CPaaS you can expect certain SLA. When there’s an outage on-premises, there is your
IT responsible for the system restore.
• Cost model - On-prem solutions involve assets that must be purchased, may need to be financed, and
must ultimately be replaced. Cloud solutions are services to which you subscribe without buying any
assets.
• Compliance - When you run it yourself, you have to worry about ensuring compliance with all the
laws and regulations that apply to your business.

16. Rationale for CTO
• Scale - Cost effective scaling is the key asset of CPaaS offering. This PAYG model which you don’t have to
bother any more.
• Support & Monitoring - Monitoring systems can run 24x7, but keeping staff around the clock can be very
expensive
• Product development and roadmap - now you can benefit from the Product roadmap provided by the 3rd
party. You can concentrate at E2E use case using existing of future features provided by the CPaaS.
• SLA - Choosing CPaaS you can expect certain SLA. When there’s an outage on-premises, there is your IT
responsible for the system restore.
• Cost model - On-prem solutions involve assets that must be purchased, may need to be financed, and must
ultimately be replaced. Cloud solutions are services to which you subscribe without buying any assets.
• Compliance - When you run it yourself, you have to worry about ensuring compliance with all the laws and
