AWS
- 5. - Cloud refers to a Network or Internet.
- Cloud is something, which is present
at remote location.
- Cloud can provide on demand services
over network.
- 8. - In which large groups of remote servers are networked to allow
centralized data storage, and online access to computer services or
resources.
- 9. - Using cloud computing,
organizations can use shared
computing and storage
resources rather than building,
operating, and improving
infrastructure on their own.
- 10. - Cloud Computing provides us a means by which we can
access the applications as utilities, over the Internet.
- 11. - It allows us to create, configure, and customize applications
online.
- 12. - It offers online data storage,
infrastructure and application.
- 14. 1. Cost
2. Resource accommodation.
3. Easy to manage.
4. No direct coupling between hardware and operating system.
5. Portability.
- 17. - Virtualization typically refers to the creation of virtual machine
that can virtualize all of the hardware resources, including
processors, memory, storage, and network connectivity using
virtualization software
- With the virtualization, physical hardware resources of a server
node can be shared by one or more virtual machines.
“Creating a computer within a computer.”
- 19. - With the virtualization, physical hardware resources of a server node can
be shared by one or more virtual machines.
- Multiple virtual machines can run simultaneously on the same physical
computer.
- Each virtual machine provides its own virtual hardware, including CPUs,
memory, hard drives, network interfaces and other devices.
- The virtual hardware is then mapped to the real hardware on the physical
machine which saves costs by reducing the need for physical hardware
systems along with the associated maintenance costs that go with it, plus
reduces power and cooling demand.
- The multiple operating systems run side-by-side with a piece of software
called a hypervisor to manage them.
- 21. - Hypervisor is also called Virtual Machine Manager(VMM).
- A Software that allows multiple operating system to share a single
hardware host.
- Using a hypervisor we can create and run number of virtual machines on
a Host node.
- A hypervisor is a virtualization technique that allows multiple
guest operating systems (OS) to run on a single host system at the same
time.
- 25. A Cloud computing model in
which an enterprise uses a
proprietary architecture and
runs servers within its own data
center
CHARACTERISTICS:
Single-tenant architecture
On-premises hardware
Direct control of underlying clod
infrastructure
TOP VENDORS:
Microsoft, Red Hat, OpenStack,
VMware, Dell EMc
Private
A Cloud computing model that
includes a mix of
on-premises,private cloud and
thirs-party public cloud services
with orchestration between the
two platform
CHARACTERISTICS:
Cloud bursting capabilities
Benefits of both private and
public environments
TOP VENDORS:
A combination of both public
and private providers
Hybride
A Cloud computing model in
which a third-party provider
makes compute resources
available to the general public
over internet. With public cloud,
enterprise do not have to set up
and maintain their own cloud
servers in house
CHARACTERISTICS:
Multi-tenant architecture
Pay as you go pricing model
TOP VENDORS:
AWS, Microsoft
Azure,RackSpace

- 30. What is AWS?
- Amazon Web Services (AWS)[ https://aws.amazon.com/ ] is a subsidiary of Amazon.com.
- It provides on-demand cloud computing platforms.
- The AWS technology is implemented at server farms throughout the world, and
maintained by the Amazon subsidiary.
- 31. Server farms
- A data center is also called a server farm
- It is a facility used to house computer systems and associated components, such as
telecommunications and storage systems.
- AWS are operated from 16 geographical regions across the world and operated using zone
and edge location.
- 33. Region
- An AWS Region is a geographical location with a collection of availability zones
mapped to physical data centers in that region.
- Every Region is physically isolated from and independent of every other Region in terms
of location, power, water supply, etc.
- You can't describe or access additional regions from an AWS account, such as AWS
GovCloud (US) or China (Beijing).
- 35. Availability Zones (AZs)
- An Availability Zone is a logical data center in a Region available for use by any AWS
customer.
- Each zone in a Region has redundant and separate power, networking and connectivity to
reduce the likelihood of two zones failing simultaneously.
- Each zone is backed by one or more physical data centers.
- Single Availability Zone can span multiple data centers, no two zones share a data cen
