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.

2. INTRODUCTIONINTRODUCTION
Cloud Computing provides us a means by which
we can access the applications as utilities, over
the Internet. It allows us to create, configure, and
customize applications online.
With Cloud Computing users can access database
resources via the internet from anywhere for as
long as they need without worrying about any
maintenance or management of actual resources.
3. What is Cloud?What is Cloud?
The term Cloud refers to a Network or Internet.
In other words, we can say that Cloud is something,
which is present at remote location.
Cloud can provide services over network, i.e.,
on public networks or on private networks, i.e.,
WAN, LAN or VPN.
Applications such as e-mail, web conferencing,
customer relationship management (CRM),
all run in cloud.
4. What is Cloud Computing?What is Cloud Computing?
Cloud Computing refers to manipulating,
configuring, and accessing the applications online.
It offers online data storage, infrastructure and application.
Cloud Computing is both a combination of software and
hardware based computing resources delivered as a
network service.
6. Basic ConceptsBasic Concepts
There are certain services and models working behind the
scene making the cloud computing feasible and accessible
to end users. Following are the working models for cloud
computing:
1. Deployment Models1. Deployment Models
2. Service Models2. Service Models
7. Deployment ModelsDeployment Models
Deployment models define the type of access to the
cloud, i.e., how the cloud is located? Cloud can have any
of the four types of access: Public, Private, Hybrid and
Community.
8.
9. PUBLIC CLOUDPUBLIC CLOUD : The Public Cloud allows systems and services to be
easily accessible to the general public. Public cloud may be less secure because
of its openness, e.g., e-mail.
PRIVATE CLOUDPRIVATE CLOUD : The Private Cloud allows systems and services to be
accessible within an organization. It offers increased security because of its
private nature.
COMMUNITY CLOUDCOMMUNITY CLOUD : The Community Cloud allows systems and
services to be accessible by group of organizations.
HYBRID CLOUDHYBRID CLOUD : The Hybrid Cloud is mixture of public and private
cloud. However, the critical activities are performed using private cloud while
the non-critical activities are performed using public cloud.
10. Service ModelsService Models
Service Models are the reference models on which the
Cloud Computing is based. These can be categorized
into three basic service models as listed below:
1.1.Infrastructure as a Service (IaaS)Infrastructure as a Service (IaaS)
2. Platform as a Service (PaaS)2. Platform as a Service (PaaS)
3. Software as a Service (SaaS)3. Software as a Service (SaaS)
11. The Infrastructure as a Service (IaaS) is the most basic level of
service. Each of the service models make use of the underlying
service model, i.e., each inherits the security and management
mechanism from the underlying model, as shown in the
following diagram:
12. Infrastructure as a Service (IaaS)Infrastructure as a Service (IaaS)
IaaS is the delivery of technology infrastructure as an on
demand scalable service.
IaaS provides access to fundamental resources such as
physical machines, virtual machines, virtual storage, etc.
Apart from these resources, the IaaS also offers:
•Virtual machine disk storage
•Virtual local area network (VLANs)
•Load balancers
•IP addresses
•Software bundles
13. Infrastructure as a Service (IaaS)Infrastructure as a Service (IaaS)
• All of the above resources are made available to end user via server
virtualization.
• resources are accessed by the customers as if they own them.
14. Infrastructure as a Service (IaaS)Infrastructure as a Service (IaaS)
Benefits :
• Full Control of the computing resources through
Administrative Access to VMs.
• Flexible and Efficient renting of Computer Hardware.
• Portability, Interoperability with Legacy Applications.
Issues :
• COMPATIBILITY WITH LEGACY SECURITY
VULNERABILITIES

16. Platform as a Service (PaaS)Platform as a Service (PaaS)
PaaS provides the runtime environment for applications,
development & deployment tools, etc.
PaaS provides all of the facilities required to support the
complete life cycle of building and delivering web
applications and services entirely from the Internet.
•Google's App Engine, Force.com are examples of PaaS
offering vendors.
•Developer may log on to these websites and use the built-in
API to create web-based applications.
17. Platform as a Service (PaaS)Platform as a Service (PaaS)
• For example, an application written in Python against Google's
API using Google's App Engine is likely to work only in that
environment.
Note : vendor lock-in is the biggest problem in PaaS.
18. Platform as a Service (PaaS)Platform as a Service (PaaS)
Benefits :
•LOWER ADMINISTRATIVE OVERHEAD
•LOWER TOTAL COST OF OWNERSHIP
•SCALABLE SOLUTIONS
•MORE CURRENT SYSTEM SOFTWARE
Issues :
•LACK OF PORTABILITY BETWEEN PAAS CLOUDS
•EVENT BASED PROCESSOR SCHEDULING
•SECURITY ENGINEERING OF PAAS APPLICATIONS
20. Software as a Service (SaaS)Software as a Service (SaaS)
SaaS model allows to use software applications as a service to
end users.
Software that is deployed on a hosted service and is accessible
via Internet.
There are several SaaS applications, some of them are listed
below:
•Billing and Invoicing System
