AWS offers “bare-metal” Mac cloud services

Amazon Web Services has announced that it is offering what it calls bare-metal Macs in its cloud, although Amazon’s definition of “bare metal” doesn’t exactly jibe with the generally accepted definition.

“Bare metal” typically means no operating system. It’s very popular as a means of what is known as “lift and shift,” where a company takes its custom operating environment, starting with the operating system, libraries, apps, databases, and so on, and moves it from on-premises to the cloud without needing to make a modification to its software stack.

Here, Amazon is offering Macs running macOS 10.14 (Mojave) or 10.15 (Catalina) on an eighth generation, six-core Intel Core i7 (Coffee Lake) processor running at 3.2 GHz. (Amusingly, the instances are run on Mac Minis. What I wouldn’t give to see a data center with racks full of Mac Minis.)

But really, it’s all they had to work with. The only other Macs are laptops, all-in-one desktops with an unnecessary monitor for cloud data centers, and the giant, overpriced Mac Pro. So this really was AWS’s only option.

EC2 Mac instances with the Apple M1 custom Arm chip are already in the works, and planned for 2021, according to a blog post by Jeff Barr, chief evangelist for AWS.

The macOS EC2 instances are accessible over SSH shell or as a VNC remote desktop with up to 32GB of memory for access to AWS services. They are fairly limited in their offerings: you can access Amazon Elastic Block Store (EBS), Amazon FSx for Windows File Server, Amazon Simple Storage Service (S3), AWS Systems Manager, and Amazon Machine Images.
