Technologies are generally described for provisioning and managing access to FPGAs as a service. In some examples, a system for allowing provisioning management for shared FPGA use and access control to enable a user's processes to access their custom programmed FPGA may accept user packages for compilation to an FPGA in communication with datacenter servers. The user packages may be imaged to the FPGA with an added management payload, and a driver and user key may be employed to allow selective access to the FPGA as a service for datacenter virtual machines. Together these elements allow a datacenter to provision rentable integrated circuits as a service (ICaaS). Additional services such as billing tracking, provision management, and access control may be provided to users allowing them to realize lower cost while the datacenter realizes greater return.
