2020-07-25A deep exploration of hardware virtualization support — how Intel VT-x and AMD-V enable efficient hypervisors through VM control structures, nested paging, and the clever elimination of slow trap-and-emulate paths.
Unikernels: Specializing the OS for a Single Application, from MirageOS to IncludeOS and the Performance-Security Trade-offs
2020-05-26A deep exploration of unikernel architecture — how compiling an application directly into a specialized operating system kernel produces dramatic performance and security benefits while challenging decades of OS design orthodoxy.
Exokernels & Library OS: MIT's Radical Vision, Secure Multiplexing, and the Unikernel Lineage
2020-04-01A deep exploration of exokernel architecture from MIT's Aegis/XOK/ExOS stack through the secure multiplexing problem to the modern unikernel renaissance that vindicated the library OS philosophy.
