The cloud has changed everything for companies all over the world, leading to an explosion in demand for skilled cloud engineers. Whether they’re maintaining an Azure buildout for a large enterprise or figuring out the best cloud-based analytics tools at a small startup, cloud engineers are critical toward building out and iterating on effective cloud platforms.
On the technical side of things, the necessary skills often depend on the size the organization, the industry, and the size of the team. For starters, though, cloud engineers should have a solid grasp of the three major cloud platforms often utilized by businesses:
A cloud engineer is expected to understand the options available on each of these platforms, including storage (and how to deploy/manage it) and compute. During the interview process, a candidate for cloud engineering position will likely face some highly technical questions designed to test their cloud-platform knowledge, so it’s not something you can fake.
As more network functions migrate to the cloud, cloud engineers should also know as much as possible about cloud-based network management, from spinning up virtual networks and servers to security. (At moments, a cloud engineer job might seem virtually identical to a network engineer job, depending on the cloudiness of the organization’s IT stack.)
Web services and APIs are also key, which means cloud engineers must be familiar with XML, SOAP, and how to automate processes.
Let’s delve into the essential skills along with the most in-demand certifications for cloud engineers. If you’re interested in jumping into this dynamic field, now’s the time!
