Modular data center

An apparatus, comprising:

• a compute housing configured to house computing equipment of an edge modular data center, the compute housing comprising:
• an exterior configured to protection an interior of the compute housing from weather;
• a first door having an electronic lock;
• an access control vestibule accessible via the first door;
• a rack assembly enclosure configured to house the computing equipment;
• a barrier separating the access control vestibule from the rack assembly enclosure;
• a plurality of lockers, each having a respective lock, and each configured to house at least some of the computing equipment, wherein
• the electronic lock is configured to selectively provide access to the access control vestibule from outside the compute housing responsive to a technician presenting a first security credential;
• the barrier is configured to selectively provide access to at least some of the lockers responsive to the technician presenting a second security credential;
• the lockers are configured to selectively provide access to interiors of the respective lockers responsive to the technician presenting a third security credential;
• and
• the compute housing is configured to be transported by truck;
• and
• one or more cooling modules coupled to the compute housing and configured to cool and circulate air into a first region of the rack assembly enclosure, through the lockers, and into a second region of the rack assembly enclosure, wherein:
• the one or more cooling modules are configured to be transported separately from the compute housing by truck and attached to the compute housing at an installation site, wherein the one or more cooling modules are configured to provided more than 150 kW of cooling to the compute housing and the compute housing is smaller than 237.5 square feet.
