What is cloud computing???
Cloud computing is possible because of
virtualization Virtualization is a technique of abstracting physical
resources and making them appear as logical resources and it may be implemented at compute, storage, and network
For a layman, virtualization can be mentioned as making the hardware resources appear as software resources
The hardware architecture of a system can be either X34 or X32 or X86. These architectures can run or host only one application so we go for virtualization which can host many applications despite of its underlying architecture
Virtualization !!!
Modern data centers in the cloud computing
environment host a variety of applications that run from few seconds to longer periods
By 2014, energy costs contribute 75% by the data centers because of insufficient hardware usage and inefficient resource usage
Consequently, energy costs for operating and cooling the equipment of data centers have increased significantly up to a point where they are able to surpass the hardware acquisition costs
Data centers are becoming warmer!!
For each watt consumed by the computing
resources an additional 0.5-1 watt is required by the cooling systems and CO2 emission also contribute to significant Greenhouse effect
According to McKinsey report on “Revolutionizing
Data Center Energy Efficiency”: A typical data center uses as much energy as
25,000 households uses. The total energy bill for data centers in 2010 was over $11 billion and energy costs in a typical data center doubles every five years
About 50% of power in the data center is consumed by the servers/storage and computer AC room consumes about 34% of power

The solution is green computing !!!!

VM Consolidation is a technique to reduce the
number of active PMs by migrating and consolidating the VMs into reduced number of physical machines
Consolidation includes two strategies
VM Placement VM Migration
VM Consolidation
VM Placement is the process of selecting the
appropriate host for the given VM For the efficient utilization of the physical
resources, VM should be placed on to the suitable host
The VM placement can be either saving energy by shutting down some severs or it can be maximizing the resources utilization and the next is VM Migration
VM Placement
Power based approach Application QOS based approach
Power based approach is for energy conservation by shutting down some servers
Application based approach is for maximizing the resource utilization and also maximizing QOS delivery by provider
Types of VM Placement
VM Migration is carried out after the initial VM
placement in order to reduce the number of running physical machines by migration of few VMs and consolidate them into reduced number of PMs
Four steps are involved in the VM machine migration process 1. select the PM which is overload or under loaded2. select one or more VMs from overloaded or under loaded
server3. select the appropriate destination PM where selected
VMs can be placed and 4. transfer/ migrate the VMs to destination PM
VM Migration
Selecting the suitable host is one of the
challenging task in the migration process, because wrong selection of host can increased the number of migration, resource wastage and energy consumption
VM Consolidation is of two types:
Static and Dynamic consolidation
In static consolidation a new VM is placed to PMs for processing and no migration takes place here
In dynamic consolidation the VMs are migrated from one PM to another whenever a necessity occurs
Types of consolidation
Reduce the amount of hardware, Reduce the data center footprints, Indirectly reduce power consumption, Cost reduction and Reduce staffing needs
Challenge in consolidation :How accurately to characterise an application’s resource requirements and resource usage over a time period
Advantages of consolidation
