Hypervisors, Containers, Virtualisation, KVM/Docker can work has hypervisor, VMWARE / PROXMOX are virtualisation OS with built in capabilit

Dockers is a container - so will need an OS, and then will make containers on top of it

so we use PDU's (Power strips) that taken an SNMP Command and supply power to the server or cut it off

we use a command that is sent via IPMI Interface to boot the PC, and check bios data and boot into OS (such as VMWARE / proxmox - which runs on debian, or xcp-ng which runs on centos, or pure simple ubuntu)

Once the machine is on, the containers spin on and start serving, all ip schemes eetc is handled by software, and when we dont need machines we just shut them down as we want to save power consumption

OS such as Ubuntu (has KVM / Docker built in) and can work as HyperVisor

VMWARE / PROXMOX are virtualisation OS with built in capabilit

Dockers is a container - so will need an OS, and then will make containers on top of it

VMWARE - No, HYPER-V No, these are proprietary Virtualiastion systems

You would either go with Proxmox / Xen or Pure simple KVM as the Base, and then inside this you will provision virtual machines that could host windows, docker etc

DC's don't use Blade Servers, Blades are for customers, not for Data Center owners. Yes we have high density servers, and yes we have stacks that let you compete with amazon. But Amazon code is not portable - so if code is written strictly for amazon - it can't be ported without changes

SDN's are a big part of how the internet gets delivered, and kubernates / dockers can't operate without them. The Stack to learn is called openstack https://www.openstack.org/) that is working on enabling how the internet and networks of the future will be built.

Your UNIFI / Amplifi all use SDN's in a matter of speaking

  1. Yes you can do vmware on raspi - but not a good idea - it's a very small machine - but for theory you can
  2. Aws uses KVM at the bottom layer and it's own version of Debian
  3. Azure uses Windows server and Hyper-V at their bottom end
  4. You can use XCP-NG (XEN) or Proxmox - System3 uses ProxMox
  5. No one uses VMWARE now :)

There are 2 types of Hypervisors Type1 and Type 2

  1. Type 2 is you will install ubunut, and then install kvm or something
  2. Type 1 is you will install VMWARE / Nutanix / Prmoxmox

VMware or Oracle Virtualbox are hypervisors that manage the host resources. They can run on bare metal or on top of another OS as windows. AWS runs such a hyper visor on its baremetal servers. Yes there is boot and bios which trips the hyper visor to fire up much as it fires up windows. hypervisor functionally is more of is a Resource mapper to the guests instead of a full blown OS that’s it.

Docker can be similarly installed on your PC as Birtualbox, it has commands to create a container or load a standard docket image of say a Ubuntu machine with OracleDV pre built by someone else.

They run atop hypervisor software that allows multiple operating systems to share the same underlying physical hardware and operate in isolation from each other. The hypervisor virtualizes the underlying hardware, and each VM runs its own operating system (OS). Containers are also software-defined computing instances, but they run atop a shared, host OS. They package software into portable, executable units with all of the necessary dependencies to run anywhere—on a laptop, on a server, in the cloud, etc.
buzz1 an overview of how servers are built and connected to storage
buzz1 the difference between Type1 and Type 2 HV's. in type 2 - there is machine + OS + hypervisor (such as window)
buzz1 how this talks - So you have VM Host physical machine VM OS HYPERVISOR and then guest OS

  1. Open stack is a collaboration of companies to do what amazon does using open source
  2. xcp-ng open source stack such as Proxmox / XCP
  3. XEN hypervisorl
  4. open stack is a stack. A stack is a collection of software components designed (and often required) to operate together as a single unit. even HP / NEC use openstack in their products.
  5. https://www.openstack.org/use-cases/bare-metal/
  6. cisco is also now making products that work with openstack
  7. https://www.nutanix.com/ - this company will run vmware out of breath
