What is a Hypervisor? Complete Guide to Virtualization Technology

A hypervisor is a key virtualization technology that allows multiple virtual machines (VMs) to run on a single physical server by managing and allocating hardware resources efficiently.

In this guide, you’ll learn what a hypervisor is, how it works, and the difference between Type 1 and Type 2 hypervisors used in cloud computing, data centers, and server environments.

Hypervisors are the foundation of modern cloud infrastructure, VPS hosting, and virtualization systems.

What is Virtualization?

Virtualization lets businesses run multiple systems using one physical machine, reducing the need for extra hardware.It creates virtual machines (VMs) like splitting one house into many rented rooms. Each VM works independently, sharing the same physical resources in a smart way.This improves efficiency, cuts costs, and makes cloud computing more powerful and scalable.This blog ‘What is Virtualization?’ explains the basics simply a great start for smarter IT decisions.

Containers vs VMs: Why Use Containers Over VMs in 2026

Containers and Virtual Machines (VMs) are powerful technologies used to create isolated computing environments by packaging applications along with their required libraries and system tools. Containers focus on speed and efficiency, enabling faster deployment and better portability. In contrast, Virtual Machines provide stronger isolation by running a complete operating system for each instance, making them ideal for supporting diverse workloads.

Choosing between containers and VMs depends on whether your priority is efficiency and portability or robust isolation. In the upcoming sections, this blog clearly explains the key differences between containers and virtual machines to help you make informed decisions. Let’s begin.

The Virtual Machine Life Cycle in Cloud Computing

Imagine being able to instantly create an exact copy of your computer whenever you need it deploy it within minutes, complete your task, and remove it when done.That’s the power of virtual machine management in the cloud environment.Understanding the virtual machine life cycle helps organizations boost efficiency, enhance security, and optimize costs.It’s not just about technology it’s about smarter, faster, and more controlled cloud operations. Mastering this process unlocks the true potential of cloud computing.

Virtual Machine Provisioning in Cloud Computing

In a traditional setup, you’d send requests, wait for approvals, buy hardware, set it up and by the time it’s ready, the project’s already halfway through!

But in the cloud world, that same setup happens in minutes thanks to virtual machine provisioning. With just a few clicks, organizations can create, configure, and deploy servers instantly. It’s like moving from building a car piece by piece to summoning one ready to drive.

This automation has completely changed how companies access computing power boosting agility, but also bringing new challenges in governance and cost control.

Virtualization vs. Cloud Computing

Virtualization and cloud computing are often linked, but they’re not the same. Virtualization creates multiple virtual machines on a single physical server, while cloud computing delivers those resources over the internet on demand. This blog breaks down their key differences and how they work together to power today’s IT infrastructure.

Google Cloud C4D machine series Compute with AMD Turin

Confidentiality VMs running AMD SEV on C4D machines preview

Google Titanium hardware gives the C4D machine series excellent, reliable, and consistent performance with 5th-generation AMD EPYC (Turin) CPUs.

Google Cloud offers Confidential Compute on AMD N2D, C2D, and C3D machines worldwide. The general-purpose C4D machine series' confidential virtual machines (VMs) with AMD Secure Encrypted Virtualisation (AMD SEV) technology are in preview today and will soon be released.

C4D virtual machines use Titanium and fifth-generation AMD EPYC Turin processors. C4D outperforms C3D by 30% on the anticipated SPECrate2017_int_base benchmark, growing performance with fewer resources and maximising expenditures.

C4D supports web, app, and game servers, AI inference, web serving, video streaming, analytics, and relational and in-memory databases.

C4D can execute 38% more Memorystore for Redis operations and 56% more Cloud SQL for MySQL queries than C3D due to its higher core frequency (up to 4.1 GHz) and improved IPC.

With C4D, AMD EPYC Turin may boost web-serving throughput per vCPU by 80% and enhance branch prediction and L3-cache efficiency.

Features of C4D machines

The C4D machine series has these traits:

Titanium and AMD EPYC Turin power it.

Supports 384 virtual CPUs and 3,024 GB DDR5.

Local Titanium SSDs up to 12,000 GiB are supported.

Preconfigured machines with 2–384 virtual central chips are available.

Future bookings, Spot VMs, and on-demand consumption are supported.

Allows conventional network setup with 100 Gbps bandwidth.

Supports Tier 1 VM networking at 200 Gbps.

For HyperDisk volumes only.

Confidential Virtual Machine AMD SEV support Flexible, resource-based committed use discounts

Supports compact and distributed placement policies.

C4D machine series types

Regular, high-cpu, and high-mem C4D virtual machines have predefined configurations from 2 to 384 vCPUs and up to 3,024 GB of memory.

Build your instance with the C4D machine type -lssd option to use Titanium SSD. Selecting this machine type creates a Titanium SSD-partitioned instance of the required size. Different Titanium SSD volumes cannot be joined.

Custom machines are incompatible with C4D.

Supported C4D VM disc types

It supports only NVMe disc interface and Hyperdisk block storage:

Hyperdisk-steady

Hyperdisk Extreme

Certain system types automatically receive local titanium SSD with the -lssd option.

Persistent Disc is incompatible with C4D.

Disc and capacity limits

A virtual machine (VM) can use a variety of hyperdisks, but their total disc capacity (in TiB) cannot exceed:

For systems under 32 vCPUs, all hyperdisks have 257 TiB.

Different computers with 32 vCPUs or 512 TiB for the hyperdisk

Networking C4D machines

Network interfaces for C4D virtual machines must be gVNIC. C4D can handle 100 Gbps for regular networking and 200 Gbps for per-VM Tier_1 networking.

Make sure your operating system image supports the gVNIC driver before switching to C4D or starting instances. Choose an OS image with “Tier_1 Networking” and “200 Gbps network bandwidth” on the Networking features tab of the OS information table for optimum C4D performance. Although the guest OS lists gve driver version as 1.0.0, these images upgrade the gVNIC driver. If your C4D instance runs an operating system with an outdated gVNIC driver, it may have greater latency or less network bandwidth than it should.

Custom OS images for the C4D machine series allow manual installation of the newest gVNIC driver. C4D instances should use gVNIC driver v1.3.0 or later. Google recommends using the latest gVNIC driver for new features and bug fixes.
