Asst. Professor
MANUU, Hyderabad

2. What is it?
● On demand delivery of IT resources via internet
● Anything that involves delivering services over the
internet
● Rather than managing files on a local storage device, cloud
computing makes it possible to save them on internet
● The most common services we know, Icloud,dropbox,google
drive

3. IT resources
Computing power Applications
Database storage

4. #1 Computing power
How fast a machine can perform an
operation
● Computer's processor interprets any
command you execute as a series of math
problems.
● CPU allows the computer to synchronize
all its components and it determines the
speed at which the computer can pull
data from its memory and perform
calculations.
● CPU creates a series of electrical pulses
at regular intervals.
● This is done by processor
● The number refers to how many
electrical pulses your CPU sends out
each second.
● A 3.2 gigahertz processor sends out
around 3.2 billion pulses each second.

5. PROCESSING POWER
Often known as CPU power, CPU cycles, and various other names, processing power is the ability of
a computer to manipulate data. Processing power varies with the architecture (and clock speed) of
the CPU. Normally A good processor speed is between 3.50 to 4.2 GHz, but it is more important to
have a single-thread performance. In short, 3.5 to 4.2 GHz is a good speed for processor.

8. #2 DATA STORAGE
WHAT IS DATA STORAGE?
● Data storage is the retention of information using technology
specifically developed to keep that data and have it as accessible
as necessary.
● Data storage refers to the use of recording media to retain data using
computers or other devices.
The most prevalent forms of data storage are file storage, block storage, and object
storage, with each being ideal for different purposes.

9. What is file storage?
Inexpensive and
simply constructed,
data is stored in files
and folders. This is
commonly found on
hard drives and means
that the files look
exactly the same to
the hard drive as they
do to the user
What is block storage?
Data is stored in
evenly-sized blocks.
Although more
expensive and complex
and less scalable,
block storage is ideal
for data that must be
frequently accessed
and edited
What is object storage?
Data is stored as
objects with metadata
and unique identifiers.
Although it is generally
less expensive to store
data this way, object
storage is only ideal for
data that doesn’t need
to be edited.

10. FILE BLOCK
OBJECT
Filestore! As fully managed
Network Attached Storage (NAS),
Filestore provides a cloud-based
shared file system for
unstructured data. It offers really
low latency and provides
concurrent access to tens of
thousands of clients with scalable
and predictable performance up to
hundreds of thousands of IOPS,
tens of GB/s of throughput, and
hundreds of TBs. You can scale
capacity up and down on-demand.
Typical use cases of Filestore
include high performance
computing (HPC), media
processing, electronics design
automation (EDA), application
migrations, web content
management, life science data
analytics, and more!
Persistent Disk and Local
SSD are block storage
options. They are
integrated with Compute
Engine virtual machines
and Kubernetes Engine.
With block storage, files
are split into evenly sized
blocks of data, each with
its own address but with
no additional information
(metadata) to provide
more context for what that
block of data is. Block
storage can be directly
accessed by the operating
system as a mounted drive
volume.
Cloud Storage is an object store
for binary and object data, blobs,
and unstructured data. You
would typically use it for any
app, any type of data that you
need to store, for any duration.
You can add data to it or retrieve
data from it as often as you
need. The objects stored have
an ID, metadata, attributes, and
the actual data. The metadata
could include all sorts of things
about security classification of
the file, the applications that can
access it, and similar
information.

25. Types of Cloud computing
Deployment Model
It works as your virtual computing environment
with a choice of deployment model depending
on how much data you want to store and who
has access to the infrastructure.
Types
1. Public
2. Private
3. Hybrid
4. Community
Service Model
Cloud computing makes it possible to render
several services, which can be defined
according to the roles, service providers and
user companies.
Types
1. Infrastructure as a service (IaaS)
2. Platform as a service (PaaS)
3. Software as a service (SaaS)

26. Public Cloud
● The name says it all. It is accessible by the public.
● Public deployment models in the cloud are perfect
for organizations with growing and fluctuating
demands.
● It also makes a great choice for companies with
low-security concerns. Thus, you pay a cloud
service provider for networking services, compute
virtualization & storage available on the public
internet.
● This is also a great delivery model for the teams
with development and testing. Its configuration
and deployment are quick and easy, making it an
ideal choice for test environments.

27. Private cloud
Companies that look for cost efficiency and greater control
over data & resources will find the private cloud a more
suitable choice.
What it means is that it will be integrated with your data
center and managed by your IT team. Alternatively, you can
also choose to host it externally. When it comes to
customization, the private cloud offers bigger opportunities
that help meet specific organization’s requirements. It’s
also a wise choice for mission-critical processes that may
have frequently changing requirements.

28. Hybrid Cloud
As the name suggests, a hybrid cloud is a combination
of two or more cloud architectures. While each model
in the hybrid cloud functions differently, it is all part of
the same architecture.
Let’s understand the hybrid model better. A company
that has critical data will prefer storing on a private
cloud, while less sensitive data can be stored on a
public cloud. The hybrid cloud is also frequently used
for ‘cloud bursting’. It means, suppose an organization
runs an application on-premises, but due to heavy load,
they can burst into the public cloud.

29. Community Cloud
The community cloud operates in a way that
is similar to the public cloud. There’s just one
difference – it allows access to only a
specific set of users who share common
objectives and use cases.
This type of deployment model of cloud
computing is managed and hosted internally
or by a third-party vendor. However, you can
also choose a combination of all three.

32. SERVICE MODELS
Cloud computing makes it possible to render several services, which can be defined
according to the roles, service providers and user companies.

33. In the case of IaaS, a third party provides the hardware and infrastructure
that a software developer uses to run its application (along with any necessary
middleware and support). For example, Amazon offers its Amazon Web
Services (AWS) for developers to build and deploy their cloud applications.
Infrastructure
As
A
Service
Platform
As
A
Service
Software
As
A
Service
PaaS is very similar to IaaS, but a PaaS vendor includes not just the
infrastructure, but also the operating system and middleware needed to serve
as the "connective tissue" for the cloud application, meaning that developers
can more easily just "plug into" the platform. The Google App Engine is a good
example of a PaaS - it's a hosting service offered by Google that allows
developers to quickly and efficiently deploy cloud apps.
SaaS is one of the most common examples of cloud applications and one that's
most familiar to ordinary users. In this version of a cloud application, the publisher
provides both the cloud-based software and the hardware and infrastructure on
which it runs. You're probably already familiar with a number of examples,
including Dropbox and Google Workspace (formerly known as Google G Suite).
