Technical requirements
In this chapter, we will cover cloud providers that require a paid account to follow the example code. If you don’t have access to a cloud account, we will also cover local builders, including QEMU, which can be used for free but requires setting up a local QEMU environment on your PC. Check the QEMU documentation or your Linux distribution guide for instructions on setting this up: https://www.qemu.org/docs/master/.
Otherwise, it may be possible to contact the cloud providers for a trial to follow along with the cloud source code examples.
