Right now your marketing speaks to people who have already implemented something across multiple different platforms - but having learned all that they're probably more willing to accept the marginal cost of maintenance than to abandon the time and effort already invested in setting it all up.
Building from scratch is a much easier and more pleasant decision than migrating. So you'll gain more users from people who want an accessible infrastructure experience that can grow with their (presently unknown) needs than with grizzled veterans - who might prefer just demanding a larger budget or more hires for infrastructure on a future project than learning a new technology that will render their previous knowledge obsolete.
Your short intro video kind of addresses this, but shows your example developer deploying her app and then 5 different infrastructure platforms with zero effort - she doesn't care about the problem until it comes to the boring maintenance stage. A lot of people would take away that the market leading technologies are super-easy to deploy and that they can just hire someone to do the maintenance while they focus on product or the business side. (Also, the music doesn't match the visual story at all and feels cringey - again, not the emotional impression you want to create.)
In general, people will go with whatever the default tool is because it's socially proven and there will be a big community of prior users who can help them through the teething problems. And there's a sense that the right tool for the right job is usually better than a do-everything tool. So you need to show where the pain points are early in the process of cloud deployment - when your target user is figuring out what infrastructure they need, and why.
