Ably surveyed over 500 engineering leaders about the challenges of building realtime edge messaging infrastructure in-house for applications like chat, delivery tracking, and collaboration tools. The study found that outsourcing to a Platform-as-a-Service (PaaS) solution provider can save time, cost, and effort compared to building edge messaging infrastructure in-house. Ably's co-founders invested over 50,000 engineering hours before launching their dependable edge messaging infrastructure in 2016. The company aims to inform developers about the benefits of using a PaaS solution for realtime applications.
