Your own AWS account. The walkthroughs create real resources; the AWS Free Tier covers many of them. Delete what you create when you finish so you don’t keep paying. Pro members can use a CloudaQube AWS sandbox instead.
How long does it take?
About 12 hours of lessons, videos and hands-on walkthroughs across 5 modules.
