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 What 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 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

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.

12 Components of Cloud Computing :

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 What 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.

Traditional

23 3. 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.

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.

26 The 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 4. 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 Imaging 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)
