I need to ensure the highest level of stability and streamability without buffering or friction for our viewers. Is an end-to-end solution of an OVP the right choice?

End-to-end solutions speed media delivery up because all aspects of streaming - from transcoding and file optimization, bitrate-adaptive delivery, seamless integration of the largest CDNs on the planet, web players and frontends like OTT players and apps, are all fully integrated, synchronized and optimized with each other. 

A full end-to-end OVP-CDN-OTT solution is exactly the setup designed to reduce buffering, friction or glitches between providers, loading times or incompatibility-caused issues - as long as it utilizes the largest and most solid top-tier CDNs, such as Akamai, Limelight or Verizon CDN - which Lightcast.com does.
