My Cloud Journey — Week 3: Virtualization
- This week's article explores virtualization, a critical component of modern IT infrastructure that has made cloud computing possible.
- Physical servers are hardware with an OS, while virtual servers rely on hypervisors to manage hardware resources; they allocate resources to each VM, ensuring they run efficiently.
- There are two types of hypervisors: Type 1 hypervisors (Bare-Metal, installed directly on the physical server) and Type 2 hypervisors (run on top of an existing operating system).
- Virtual machines require CPU, memory, storage, and network, which are essential for VM performance. Proper allocation is crucial.
- Virtualization enables more efficient resource utilization, improved system scalability, and increased flexibility, as it allows VMs to be easily moved between hosts to balance resource utilization.
- VMs can be converted from physical servers to run on hypervisors. It offers benefits such as standardization and mobility.
- Understanding virtualization is fundamental to modern IT infrastructure management and lays a solid foundation for advanced cloud computing topics.
- In the upcoming week, the author plans to explore databases, with a focus on SQL (Structured Query Language).
- Virtualization is a fascinating topic critical for aspiring cloud architects to comprehend.
- Efficiency, mobility, and elasticity are the primary benefits of virtualization.
