An introduction to Cloud Computing Services

1. CLOUD COMPUTING
Sr. Italia Joseph Maria
Assistant Professor
PG Dept of Computer Applications
Marian College Kutikanam Autonomous

2. • In the simplest forms, Cloud
Computing means storing
and accessing data, files
and programs over the
internet.
• With Cloud Computing,
users can access files, data,
storage and applications
from any device that can
access the internet.
“……THE USE OF
HARDWARE
AND SOFTWARE
TO DELIVER A
SERVICES OVER
A NETWORK.”

3. Examples of
Cloud Computing
• Software-as-a-service(Saas)
• Infrastructure-as-a-service(Iaas)
• Platform-as-a-service(Paas)
• File Sharing + Data Storage
• Big Data Analysis
• Data Governance
• Cybersecurity

4. Cloud Computing Service Providers
 Microsoft Azure
 Google Cloud
 Alibaba Cloud
 IBM Cloud
 Oracle
 Amazon Web Services
 Salesforce
 SAP
 Rackspace
 VMWare

5. Types of Cloud Computing

6. Cloud Service Models
Saas –Software as a Service
Paas –Platformas a Service
Iaas –Infrastructure as a Service

7. SAAS – Software
as a Service

8. “… is a way of
delivering
applications
over the
internet as a
service.”
Instead of installing and
maintaining software,
you simply access it via
the Internet, freeing
yourself from complex
software and hardware
management

10. HOW DOES NETFLIX WORK?
Find your suitable tabs at the top of Home, TV Shows, Movies, New
My List, and Watch Again. Scroll down, and you’ll search series and movies
categorized by Trending Now, Top 10 in the U.S. Today, Comedies,
crime dramas, Action Movies.
HOW DOES NETFLIX WORK
ON CLOUD ?
• Netflix uses AWS for
almost everything
• Cloud Computing
Includes… Online storage
recommendation engine,
video transcoding,
databases, and analytics.
• Most of the $1 billion
plans to spend on cloud
services will go to

11. PAAS – Platform
as a Service

12. “…..provides you computing platforms
which typically includes operating system,
programming language execution
environment, database, web server etc….”
“….allows us to avoid the expense and
complexity of buying and managing
software licenses, the underlying
application infrastructure and
middleware, container orchestrators
such as Kubernetes or the
development tools and other
resources…”

13. Openshift

14. ”…is a private platform as a service (PaaS) for organizations that
deploy and manage OpenShift on their own on-premises hardware or
on the infrastructure of a certified cloud provider.”
It is dedicated to the build
and the deployment of
containerized applications,
without the complexity of
managing the infrastructure
behind it.

15. IAAS - Infrastructure
as a Service

16. “…is a form of cloud computing that provides
virtualized computing resources over the internet…”
“…is the utilization of APIs to manage the
lowest levels of network infrastructure, including
networking, storage, servers, and
virtualization….”
BENEFITS
• SCALABILITY
• COST SAVINGS
• TIME SAVINGS
• RAPID INNOVATION
• HIGH AVAILABILITY
• IMPROVED SECURITY

17. rackspace

18. “…is a managed cloud computing company that aims to make it
easy to manage private and public cloud deployments…”
WHY?
ofFers multiple IaaS options, with service levels to match your needs. All service
levels include always-on service, plus 24x7x365 access to their architecture advisors,
cloud engineers, cloud services support staff and security experts.
