The document discusses cloud computing, including definitions, benefits, characteristics, service models, and major cloud providers. It defines cloud computing as storing and accessing data and programs over the Internet instead of a computer's hard drive. The main benefits are pay-per-use pricing, availability, optimization of resources, disaster recovery, agility, and flexibility. Characteristics include on-demand self-service, broad network access, resource pooling, and rapid elasticity. The three main service models are Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). Major cloud providers are Amazon Web Services (AWS), Microsoft Azure, Google Cloud, Alibaba Cloud,

COUMPUTING

2. What is Cloud Computing
•Cloud Computing means
storing and accessing data
and programs over the
Internet instead of your
computer's hard drive.
The cloud is just a metaphor
for the Internet.

3. Benefits Of Cloud
• Cloud Follows Pay for What you Use Model
• 24*7 Availability and Performance Oriented
Infrastructure
• Cloud Technology believes in Optimization
of Existing Resources
• Disaster Recovery Plan Help to Restore Data
Quickly on Cloud
• Agile Development on Cloud
• Organizations Experience Device
Independence
• Cloud, Cost-Effective in Nature
• Cloud Architecture is Exceptionally Flexible

4. Characteristics
• On-demand self-service: This means
that cloud customers can sign up for,
pay for and start using cloud resources
very quickly on their own without help
from a sales agent.
• Broad network access: Customers
access cloud services via the Internet.
• Resource pooling: Many different
customers (individuals, organizations or
different departments within an
organization) all use the same servers,
storage or other computing resources.

5. • Rapid elasticity or expansion: Cloud
customers can easily scale their use of
resources up or down as their needs
change.
• Measured service: Customers pay for
the amount of resources they use in a
given period of time rather than paying
for hardware or software upfront. (Note
that in a private cloud, this measured
service usually involves some form of
chargebacks where IT keeps track of
how many resources different
departments within an organization are
using.)

6. Types of Service Models
Software As A
Service
Platform As A
Service
Infrastructure As A
Service

7. Service Model
Software as a Service (SaaS)
• SaaS is a software delivery method that
provides access to software and its
functions remotely as a Web-based service.
• Instead of paying an upfront fee to
purchase and/or license software, SaaS
customers pay a recurring (often monthly
or annual) fee to subscribe to the service.
In general, they can access the SaaS from
any Internet-connected device, any time
day or night.
• Well-known examples of SaaS include
Salesforce.com, Microsoft Office 365,
Google G Suite, Dropbox, Adobe Creative
Cloud and others.

8. Platform as a Service (PaaS)
• PaaS is a computing platform being delivered
as a service. Here the platform is outsourced in
place of a company or data center purchasing
and managing its own hardware and software
layers.
• Most PaaS are designed for developers and aim
to simplify the process of creating and
deploying software.
• For example, a Web developer might use a PaaS
that includes operating system software, Web
server software, a database and related Web
development tools. The leading PaaS vendors
include Amazon Web Services, Microsoft Azure,
IBM and Google Cloud Platform.

9. Infrastructure as a Service (IaaS)
• Computer infrastructure, such as
servers, storage and networking
delivered as a service.
• IaaS is popular with enterprises that
appreciate the convenience of having
the cloud vendor manage their IT
infrastructure. They also sometimes see
cost savings as a result of paying only
for the computing resources they use.
• The leading IaaS vendors include
Amazon Web Services, Microsoft Azure,
IBM and Google Cloud Platform.

10. TOP COMPANIES
PROVIDING CLOUD
SERVICES

12. AWS CLOUD
Amazon launched AWS during cloud
computing's early transitional phase.
Prior to the launch, Amazon rebuilt its
infrastructure to consolidate server power
and storage after realizing their host servers
were approximately 50 percent below
capacity.
AWS resides on the same infrastructure as
the host of Amazon's other Web properties,
such as Web store.

13. AZURE CLOUD
• Microsoft Azure, formerly known as
Windows Azure, is Microsoft's public
cloud computing platform.
• It provides a range of cloud services,
including those for compute,
analytics, storage and networking.
• Users can pick and choose from
these services to develop and scale
new applications, or run existing
applications, in the public cloud.

14. GOOGLE CLOUD
• Google offers many other services
and APIs, only the services below are
covered by the Google Cloud
Platform terms of service, service
level agreements (if applicable), and
support offerings.

15. ALIBABA CLOUD
• Apsara system of Alibaba Cloud was
born. Despite facing arduous
challenges, Alibaba Cloud finally
grew into a mature cloud provider
and benefited millions of
organizations across the globe.
• As dreamers and entrepreneurs,
Alibaba Cloud believes that by
developing our own technologies and
having a dedicated R&D team is the
best way to ensure the company
endures the passage of time.

18. How does Cloud Works?

20. Recent Updates in Cloud
Google Cloud has announced the launch of a managed cloud-hosted
hardware security module (HSM) service – joining Amazon Web
Services and Microsoft Azure in this security benchmark.
• The Cloud HSM will enable customers to host encryption keys and
perform cryptographic operations in FIPS 140-2 Level 3 certified
HSMs, according to a company blog post.
• To put this in perspective, the highest level for the FIPS 140-2
standard is Level 4, which aims to “provide a complete envelope of
protection around the cryptographic module with the internet of
detecting and responding to all unauthorised attempts at physical
access.” Level 3, instead, requires “a high probability of detecting
and responding to attempts at physical access, use or modification
of the cryptographic module.”
• Cloud HSM is tightly integrated with Google’s Cloud Key
Management Service (KMS), which enables data protection in
services such as BigQuery, Google Compute Engine, Google Cloud
Storage and DataProc with a hardware-protected key.

21. • The move came about, according to product manager Il-Sung Lee,
because customers wanted more options to protect sensitive
information and meet compliance mandates. This is despite Google
claiming to be the only cloud provider that encrypts all customer data
at rest.
• “For those of you managing compliance requirements, Cloud HSM can
help you meet regulatory mandates that require keys and crypto
operations be performed within a hardware environment,” wrote Lee.
“In addition to using FIPS 140-2 certified devices, Cloud HSM will allow
you to verifiably attest that your cryptographic keys were created
within the hardware boundary.”
• Some may consider that this has been a long time coming for Google;
Microsoft announced Azure Key Vault, a cloud-hosted HSM-backed
service for managing cryptographic keys, as far back as the start of
2015. AWS’ CloudHSM tool is also widely documented.
• Yet Google’s cloud operations have certainly been innovative
elsewhere of late. Earlier this month the company announced
the launch of pre-packaged AI services, around contact centres and
talent acquisition, as well as supporting NVIDIA’s Tesla P4 GPUs, for
graphics-intensive and machine learning applications.
