I also thought I'd never use it. At some point I realized that Amazon's free tier allows me to execute some minor periodic tasks (like hourly site monitoring, verification that backups have been performed, an easy way to send notifications to myself).

This way, the deployment issue of an application and its maintenance kind of goes away. It's also free, meaning I don't have to spend any more money or pack the code in another server.

As I like to joke, I am a simple liberal arts major...with about 24 years on/off Wall Street. Have been an intermediate user of R seemingly forever. While I find node.js painful, early days still, the capabilities that I have and will have in the near future to improve my Shanghai based professional services business speaks to the power of the technology/framework, whatever you want to call it. Working on a Hugo website and then will move to microservices offerings to clients both as lead generators and new service offerings. I am psyched.

As an aside, I've messed with EC2, and used Linode and DO hosting Dokku and Docker containers. Can't complain as they are excellent service providers. Still not worrying about the server is a g-d send for those who just want to get stuff up.

Queuing works great when you have mostly constant load. Take image resizing, if you size a queue system to handle resizing 10k/images a day it will fall over on the day you get a million. If you use serverless it might cost a few extra bucks but you will not have a capacity problem.

The million at once thing happens more often then you think, take the case where a website gets a new logo. Now you have to redo the watermark on all the images. Or maybe you want to convert your jpg to webp.

You can also use lambdas to process your images on-the-fly as clients request them. We use both pre-process and on-the-fly depending on if we need hashes ahead of time.

It's not there yet (so, admittedly not a particularly practical answer to your question) but what I envision it to be in the future is an expansion of the "functions as a service" paradigm: Deploying functions and building blocks without having to worry about plumbing, infrastructure and cross-cutting concerns such as security or logging.

Serverless is a misnomer; what’s important is that it’s provisionless.

That means you won’t have to preallocate (and pay for) resources that will go unused during non-peak load. It enables automatic scaling.

There are plenty of “serverless” offerings for computation, but very few for databases. Without the later, I don’t think it has much value.
