Virtualization and Hypervisor

Virtualization allows 𝗺𝘂𝗹𝘁𝗶𝗽𝗹𝗲 𝗼𝗽𝗲𝗿𝗮𝘁𝗶𝗻𝗴 𝘀𝘆𝘀𝘁𝗲𝗺 instances to run concurrently on a single computer.

🔹 Type 1 (Bare Metal) - Hypervisor software runs directly on top of the hardware.
Example : 𝗘𝗦𝗫𝗶, 𝗖𝗶𝘁𝗿𝗶𝘅 𝗫𝗲𝗻𝗦𝗲𝗿𝘃𝗲𝗿...

🔹 Type 2 (Hosted) - Hypervisor software runs as an application within an Existing OS.
Example : 𝗩𝗠𝘄𝗮𝗿𝗲 𝗪𝗼𝗿𝗸𝘀𝘁𝗮𝘁𝗶𝗼𝗻, 𝗩𝗠𝗪𝗮𝗿𝗲 𝗣𝗹𝗮𝘆𝗲𝗿...

▶ Allow an operating system to run independently from the underlying hardware through the use of virtual machines.

▶ Share virtual computing, storage and memory resources.

▶ Can run multiple operating systems on top of one server (𝗯𝗮𝗿𝗲-𝗺𝗲𝘁𝗮𝗹 𝗵𝘆𝗽𝗲𝗿𝘃𝗶𝘀𝗼𝗿) or installed on top of one standard operating system and isolated from it (hosted hypervisor).
