The joke used to be that no piece of software was complete until it could send and receive email.

Whether you’re delivering customer service, connecting community members, or helping colleagues communicate, realtime chat is quickly becoming a standard part of the web developer’s toolkit.

Yesterday, Thursday 15th September, Adobe agreed to buy the collaborative design tool Figma for $20bn. Figma is a browser-based tool that enables team members to work together simultaneously to create, modify and comment upon designs in realtime. It’s part of a new breed of online tools that enable the creative process to be live and collaborative. Figma was rumored to be in the running for acquisition by Microsoft, and Adobe has paid top price to snap it up.
This blog post is the first in what we intend to be a series to detail Ably’s journey in building the next iteration of our global network. It focuses on the design and we will follow up with posts detailing the building, and finally migration from old to new. If you are interested in how you can network AWS accounts together on a global scale then read on! Ably operates a global network spanning 8 AWS regions with hundreds of additional points-of-presences.
