Study Notes
Virtualization
- Virtualization allows multiple operating systems and applications to run on a single machine.
- The physical machine is called the host machine and the virtual machine is called the guest machine.
- A hypervisor or virtual machine manager (VMM) is a software that creates and runs virtual machines.
- The hypervisor manages the allocation of physical resources among virtual machines.
- There are two types of Hypervisors: Type 1 (Bare Metal) and Type 2 (Hosted).
Type 1 Hypervisors (Bare Metal)
- The hypervisor is installed directly on the physical machine, making it the first layer over hardware resources.
- Examples of Type 1 hypervisors include VMware vSphere/ESXi, Microsoft Hyper-V, Citrix Hypervisor (XenServer), Red Hat Enterprise Virtualization (RHEV), and Kernel-Based Virtual Machine (KVM).
Type 2 Hypervisors (Hosted)
- An operating system is first installed on the physical machine, and then the hypervisor is installed over it.
- The operating system on the physical machine is called the host operating system while the virtual machines run on top of it.
- Examples include VMware Workstation, Oracle Virtual Box, Microsoft Virtual PC, and Oracle VM Server for x86.
Virtualization and Cloud Computing
- Virtualization is a fundamental part of cloud computing.
- Cloud computing automates the interaction with the hypervisor using an Application Programmable Interface (API).
- Data center virtualization is a foundation of cloud computing, providing access to pooled resources.
Network Virtualization
- Network virtualization combines network resources, such as switches, routers, and firewalls, to centralize administrative tasks.
- Administrators can adjust and control these elements virtually, simplifying network management.
Storage Virtualization
- Storage virtualization abstracts physical storage resources and presents them as logical units to applications or systems.
- It improves efficiency, speed, and utilization of storage infrastructure.
- It is commonly used in Storage Area Networks (SAN).
Application Virtualization
- Application virtualization separates the application layer from the hardware and operating system.
- Applications can run independently of the physical machine's operating system.
- Users can run Windows applications on Linux or vice versa.
Desktop Virtualization
- Administrators can deploy simulated desktop environments on a remote server, allowing users to access their desktops from any device.
- It simplifies updates, security checks, and configurations for all virtual desktops.
Data Virtualization
- Data virtualization provides a single point of access to data from multiple sources, regardless of location, format, or source.
- It allows applications to access all data as if it were stored in a single location.
Containerization in Cloud - Docker
- Docker is an open-source software container system that allows for the creation and management of application environments using Linux containers.
- It addresses challenges related to complex, multi-node application deployments.
- Docker containers are highly portable, lightweight, and faster to start up, offering scalability and cost efficiency.
- Docker facilitates resource sharing and pooling within cloud environments.
