The video calls feature of this is a VERY interesting twist: when I'm pairing with someone via MS Teams usually we're just remote-viewing Visual Studio (and pushing/pulling code from git) but every so often it's necessary to share the screen to show what the app is doing or what the logs are doing locally. The video feature, while advertised as "see the face of your colleague" would be really useful for showing the telemetry or screen of the app you're working on together -- without the need for an external conferencing app.
Could you imagine if Amazon acquired JetBrains and GitLab and made "Code with JetBrains, Git/CI/CD with GitLab, Deploy to AWS" easier than doing it any other way they could permanently prevent GCP or Azure from threatening their lead in the cloud.
But that would take vision, charisma, the willingness to take bold steps... so it will never happen.
The nice thing is that they don't even need to acquire them, both product are open-source. AWS already has CodeCommit so I wouldn't be surprised if they came up with some integrated CI/CD that automatically builds all of your code and deploys to autoscaled EC2/Lambda instances. Indeed, close the gap with the editor (or some hybrid process) and you can have your own Google's dev infrastructure (https://cacm.acm.org/magazines/2016/7/204032-why-google-stor...).
Imagine you browse the AWS public hosting repo, you click "fork" and are immediately brought into a web-based IDE, you share the url with a friend who comes and joins you for some extreme programming, every change gets built on AWS and unit tests are run automatically and the result is shown in a background tab, you click on "commit" and the code (that was already tested) is instantaneously deployed on instances that have been automagically sized, and after 10 mins of cooking you get an URL with your service in production.
There's a real risk of lock-in but I'd love to have that experience. It could also help bring more people into programming and dissolve the "magicness" of it
