If you are starting to flirt with using the cloud at your business, chances are you’ve probably taken a hard look at Azure from Microsoft. Odds are you have a few Microsoft products in your architecture already and it only seems natural that they would probably work best in the cloud that’s run by and designed for Microsoft products.
Now, as much as every geek would love to say, “Let’s build it all in the cloud right now!” Chances are, unless you are a startup company, moving your infrastructure to the cloud will probably be done in phases and projects over time depending on the size of your company and IT infrastructure, and budget.
You will most likely end up with a hybrid environment for a while or permanently before possibly transitioning to a cloud-only environment.
The following link from Microsoft is a great starting place on architecting that hybrid environment and securing the link between the two.

Or maybe you already have a hybrid environment and could use some best practices on servers or application deployments. Azure is a huge environment and it’s challenging to remember all the boxes and levers you need to check or pull to build something in the most secure manner. This checklist is very thorough and should cover the majority of workloads you might use in the Azure cloud environment.

And lastly, maybe Azure is completely foreign to you and you need to start studying and learning more about it. There are tons of resources available. You can find books on Amazon as well as purchase great courses on Udemy and linuxacademy.com. You can also start with some high-quality free content from Microsoft on their Microsoft Learn platform.
