A short series on one product, written when it reached 1.0. The first post says what Lab Builder is and why a lab per student needs more than a build script. The second shows what a student actually receives, how phases let a lesson start in the right place, and why the hardware sets the class size. The third is the delivery: a site survey that becomes a site file, an offline kit, and a check at the end that proves a student can request a lab. For platform teams and trainers who need hands-on VCF environments and would rather not build them by hand. Read them in order, then carry on with Nested Labs as Code for the inside of it.
