Virtualization in Cloud Computing | What is Virtualization | Intellipaat

Summary

In this session, you'll dive into the world of virtualization and cloud computing. The video explains how virtual machines (VMs) are used to host applications online, highlighting the growing shift from on-premise to cloud-based IT workloads. Key concepts such as virtualization, hypervisors (Type 1 and Type 2), and cloud computing are explored, alongside the AWS ecosystem. You'll learn how virtualization enables cost-effective and flexible computing environments, and how AWS utilizes hypervisors like Zen and KVM. The session wraps up by guiding users on how to set up an AWS account to get hands-on with cloud services.

Takeaways

• 😀 Virtual machines running on cloud servers are increasingly popular for hosting applications as IT workloads shift from on-premise to cloud environments.
• 😀 Virtualization on the cloud is key to creating scalable and cost-effective compute environments.
• 😀 Cloud computing can be defined as virtualized compute environments over the internet or intranet, combining virtualization and internet connectivity.
• 😀 The internet is a global network that connects billions of devices, while an intranet is a local network within a specific organization or area.
• 😀 Virtualization allows you to create a virtual version of operating systems, servers, storage, or networks, enabling efficient use of resources without the need for additional hardware.
• 😀 A hypervisor is a technology used to create virtualized environments, managing virtual machines (VMs) and providing them with resources like CPU, RAM, and storage.
• 😀 Type 1 hypervisors (bare-metal) run directly on hardware, whereas Type 2 hypervisors (hosted) run on top of an operating system.
• 😀 AWS uses a Type 1 hypervisor called Zen, an open-source virtualization platform used by major cloud providers like AWS and OpenStack.
• 😀 AWS also utilizes KVM (Kernel-based Virtual Machine) as a hypervisor in certain cases, providing flexibility for different workloads.
• 😀 Cloud providers like AWS offer various virtual machine services, such as EC2, Lambda, and RDS, to help scale and manage workloads efficiently.
• 😀 AWS provides a management console with multiple services like EC2, S3, and RDS, which users can interact with to manage their cloud resources.

Q & A

What is the main focus of the session in the script?

The session focuses on virtualization in cloud computing, explaining its importance, benefits, and different types of virtual machine services on various cloud providers.

Why are virtual machines becoming increasingly popular in cloud computing?

Virtual machines are becoming more popular because many IT workloads are shifting from on-premise environments to the cloud, making virtualization a crucial part of the current IT landscape.

How is cloud computing defined in the script?

Cloud computing is defined as a virtualized compute environment over the internet or intranet, combining both virtualization and internet technologies to allow remote access to resources.

What is the difference between Internet and Intranet as described in the script?

The Internet is a global computer network providing communication and information across interconnected networks, while Intranet is a private local network that uses the internet for communication within a specific organization or group.

What is the role of a hypervisor in virtualization?

A hypervisor is a technology that creates a virtualized environment, allowing virtual machines to run on a host operating system. It manages the virtualized resources like CPU, RAM, and storage for the virtual machines.

What are the two types of hypervisors mentioned in the script?

The two types of hypervisors are Type 1 (bare-metal) hypervisor, which runs directly on hardware, and Type 2 (hosted) hypervisor, which runs on top of an operating system.

What is the significance of virtualization in cloud computing?

Virtualization in cloud computing allows for the creation of large, scalable compute environments at a lower cost by using virtualized resources such as CPU, RAM, and storage, instead of physical machines.

Which hypervisor does AWS use for its cloud infrastructure?

AWS uses the Zen hypervisor, an open-source virtualization platform, for its cloud infrastructure. It is a Type 1 hypervisor, meaning it runs directly on hardware without an underlying operating system.

What does the AWS management console provide?

The AWS management console provides a user interface to manage AWS services. It includes services for computing, storage, database management, network, security, application integration, and more.

What is the process to create an AWS account as described in the script?

To create an AWS account, visit the AWS website, register using an email ID, and provide credit card information. AWS may charge a small refundable amount for verification purposes.
