3. The course has some prerequisites:
The participant should have some basic skill sets
like loading an OS, booting a system from CD,
Network Configuration, Thumb Drive etc.,
Users should be conversant with Protocols like
TCP,CIFS, NFS etc.,
All the modules mentioned above can be learnt
independently but the Virtualization of processing
power should be learnt first.
A basic understanding of Networks, Internet
Connectivity etc is essential.

5. 5What is MAINFRAME Technology?
A mainframe computer is a very large computer capable of
handling and processing very large amounts of data quickly.
They are used by large institutions, such as government
agencies and large corporations.
6. 6
What is Enterprise client-server?
Enterprise computing is the name given to distributed
computing as practiced in medium-sized or large organizations
where the need to share data between physically-distributed
sites is the primary motivator for the creation of a distributed
system.
In some ways, mainframes are more powerful than
supercomputers because they support more
simultaneous programs.
7. 7
What is Cloud Technology?
Cloud is a broad term and cannot be easily expanded in one
single line. Cloud can be IaaS, PaaS, AaaS and again there
are many internal small things that have to be understood to
have a clear grip on the massively disruptive technology.

1. Virtualization of Processing Power
2. Virtualization of Storage
(aka SDS - Software Defined Storage)
3. Virtualization of Networking
(aka SDN - Software Defined Networking)
4. Identity Access Management (IAM)
5. Imaging Service
13. 13What is Virtualization ?
In computing, virtualization refers to the act of creating
a virtual (rather than actual) version of something, including
(but not limited to) a virtual computer
hardware platform, operating system (OS), storage device,
or computer network resources.

23. 233. Virtualization of Networking (aka SDN - Software Defined
Networking)
Software-defined networking (SDN) is an approach to
computer networking that allows network administrators to
manage network services through abstraction of lower-level
functionality. This is done by decoupling the system that
makes decisions about where traffic is sent (the control
plane) from the underlying systems that forward traffic to the
selected destination (the data plane). The inventors and
vendors of these systems claim that this simplifies
networking.[1]
SDN requires some method for the control plane to
communicate with the data plane.
SoftwareDefinedNetworking
24. 24
Control Plane: A major function of the control plane is deciding
which routes go into the main routing table
Data Plane: In routing, the forwarding plane, sometimes called
the data plane, defines the part of the router architecture that
decides what to do with packets arriving on an inbound
interface.
SoftwareDefinedNetworking
26. 26The Three Key Elements of SDN:
Ability to manage the forwarding of frames/packets and
apply policy;
Ability to perform this at scale in a dynamic fashion;
Ability to be programmed.

28. 284. Identity Access Management:
Identity management (IdM) is the task of controlling
information about users on computers. Such information
includes information that authenticates the identity of a user,
and information that describes information and actions they
are authorized to access and/or perform. It also includes the
management of descriptive information about the user and
how and by whom that information can be accessed and
modified. Managed entities typically include users, hardware
and network resources and even applications.
In computing, identity management (IdM) describes the
management of individual principals, their authentication,
authorization, and privileges within or across system and
enterprise boundaries with the goal of increasing security and
productivity while decreasing cost, downtime and repetitive
tasks.

31. 31Imaging Service:
Imaging Service is a generic term and is being used almost
everyday by the Administrators even general users also.
Whenever we are using a bootable CD, we are using an
Imaging Service. ISO image is a classic example of Imaging
Service.
Every Commercial or non commercial entities are providing
proprietary formats as far as Imaging Service is concerned:
A multi-format image registry, the image service allows uploads
of private and public images in a variety of formats, including:
1.Raw
2.Machine (kernel/ramdisk outside of image, a.k.a. AMI)
3.VHD (Hyper-V)
4.VDI (VirtualBox)
5.qcow2 (Qemu/KVM)
6.VMDK (VMWare)
7.OVF (VMWare, others)

After Using Virtualization you can give the following
•Software as a Service (SaaS)
•Platform as a Service (PaaS)
•Infrastructure as a Service (IaaS)
•IT as a Service
•Storage-as-a-service
•Database-as-a-service (DaaS)
•Information-as-a-service
•Process-as-a-service
•Application-as-a-service (AaaS)
•Integration-as-a-service
•Security-as-a-service
•Management/governance-as-a-service(MaaS)
•Testing-as-a-service
•Green IT

The above mentioned modules are individual but can be
assembled to have a seamless functionality.
This is what has been done by the following Cloud
Management Platforms (CMP):
VMware VCloud
Microsoft Azure
