This document discusses different techniques for virtual machine migration. It begins with an introduction to virtualization and how virtual machine migration involves copying a VM from one physical machine to another. There are three main categories of migration techniques: fault tolerant techniques which migrate VMs to prevent failures, load balancing techniques which distribute load across servers, and energy efficient techniques which optimize resource utilization to conserve energy. Live VM migration is described as migrating the entire OS and applications between physical machines without disrupting applications. The document also covers background details on virtual machine migration methods being either hot/live where the VM continues running, or cold/non-live where the VM status is lost during migration.

Implementation levels of virtualizationGokulnath S
Virtualization allows multiple virtual machines to run on the same physical machine. It improves resource sharing and utilization. Traditional computers run a single operating system tailored to the hardware, while virtualization allows different guest operating systems to run independently on the same hardware. Virtualization software creates an abstraction layer at different levels - instruction set architecture, hardware, operating system, library, and application levels. Virtual machines at the operating system level have low startup costs and can easily synchronize with the environment, but all virtual machines must use the same or similar guest operating system.
On-demand computing refers to a delivery model where computing resources are made available to users as needed. These resources can be maintained within a user's enterprise or provided by a cloud service provider, in which case it is referred to as cloud computing. Effective use of cloud computing requires properly provisioning resources to avoid over-provisioning, which wastes money, and under-provisioning, which hurts performance. Efficient resource provisioning in the cloud is challenging due to the variety of VM types, pricing models, demand and cost uncertainties, and the need to balance multiple objectives like cost and quality of service.
Cloud computing provides shared resources, software, and information over the internet. It allows users to access applications from anywhere without installing them. There are three main types of cloud computing - public cloud (resources owned by a cloud provider and shared among customers), private cloud (dedicated resources for a single organization), and hybrid cloud (combination of public and private). The main components of cloud computing include SaaS, PaaS, IaaS, and utility computing. The advantages are flexibility, low costs, easy management, and scalability while the disadvantages include dependency on providers and security risks.

4. INTRODUCTION TO CLOUD COMPUTING
• Cloud computing was a hazy term, in the sense computing would occur in remote
location without the need of human intervention.
• In the real world, computing developed progressively and can be viewed in two
stages. One is more centralized and the other is desktop.
• The limitations of centralized computing did not give users enough control was
flexible.
5. HISTORY OF CLOUD COMPUTING
