What do I expect from serverless or, for that matter, any type of deployment services?

Personally, I do not think that managed Functions as a Service are a good idea. Functions are too small for my taste. The execution model in which each request is served by a fresh instance is deeply flawed. The pricing is too high for my budget.
All that being said, I can see use cases where managed FaaS is a perfect fit, but only if that would be the only flavor of serverless deployments. But it's not, even though many are putting the equation between FaaS and serverless computing.

We should ask two significant questions when contemplating whether we should use managed Functions as a Service (FaaS) flavor of serverless computing. Should we use them? If we should, shall it be AWS Lambda, Azure Functions, Google Cloud Functions, or something completely different?
So, should we use managed FaaS? We probably should. But that's not the right question. We can almost certainly find at least one good example. A more important question is whether managed FaaS can be the solution for a significant percentage of our workload. That's the question that is much more difficult to tackle. To answer it, we might need first to establish good use cases for deploying and running functions.

Linux Shell is essential and I will not go into great length to explain the reasons given that I am assuming that you already know that. So, we'll jump straight into Windows Subsystem for Linux (WSL). It lets us run Linux environment directly on Windows, and without the overhead of a virtual machine. It is part of Windows (not a replacement), so you can keep doing "Windows stuff", while still benefiting from Linux Shells and quite a few other things. It is a much better solution than using Shell emulators like Cygwin or GitBash, and it saves you from wasting resources on a virtual machine. WSL might be the best thing that happened to Windows, at least during the last couple of years.
Deployment strategies affect everyone, no matter whether we are focused only on a single aspect of the application lifecycle or we are in full control. The way we deploy affects the architecture, testing, monitoring, and many other aspects. And not only that, but we can say that architecture, testing, and monitoring affect the way we deploy. All those things are closely related and affect each other.
We'll discuss different deployment strategies and answer a couple of questions. Is your application stateful or stateless? Does its architecture permit scaling? How do you roll back? How do you scale up and down? Do you need your application to run always? Should you use Kubernetes Deployments instead of, let's say, StatefulSets? Answers to those questions will not serve much unless we are familiar with some of the most commonly used deployment strategies. Not only that knowledge will help us choose which one to pick, but they might even influence the architecture of our applications.

We all live in difficult times. Coronavirus pandemic is raging. There is the danger of a global crisis. Many of us are confined to our homes.
I believe that this is the moment when we should re-evaluate our priorities on many different levels, professional being one of them. We should all take this opportunity of being at our homes to raise our profile and become more proficient at our jobs. We cannot know for sure what the future brings. But, whatever it is, it's always best to be prepared. Professionally, the best way to be ready for turbulent times is to learn.
