This document provides an overview of cloud computing concepts and Amazon Web Services (AWS). It defines cloud computing and its service models of infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS). It also outlines the deployment models of public, private, and hybrid clouds. The document then explains that AWS is an IaaS as it provides compute and storage infrastructure, a PaaS by allowing deployment and management of applications, and includes a software marketplace. It describes how AWS services interact through the use of virtual private clouds to connect resources like Elastic Beanstalk, RDS, and more.

What is Cloud Computing?
It is the use of remote servers on the internet to store, manage and process data rather than a
local server or your personal computer.

Cloud Computing
• Provides virtualized computing resources over the
Internet
• No worries about the underlying physical machine.
• Abstract the user from the physical machine

Cloud Computing
• No control over the underlying architecture including
operating systems, storage, servers etc.
• The Cloud Provider gives the ability to the customer to
deploy customer created application using programming
languages, tools etc that are provided by the Cloud
Provider.
Platform as a Service

SaaS
Cloud Computing
• Cloud Provider leases applications or softwares which are
owned by them to its client
• Example: salesforce.com provides the CRM(Customer
Relation Manager) on a cloud infrastructure to its client and
charges them for it, but the software is owned by the
salesforce company only
Software as a Service

Deployment Models – Public Cloud
Private Cloud
Hybrid Cloud
Public Cloud
• Easy and inexpensive set-up because hardware, application
and bandwidth costs are covered by the provider.
• A service provider makes resources, such as applications and
storage, available to the general public over the Internet.
• No wasted resources because you pay for what you use

Hybrid Cloud
Public Cloud
• Private cloud gives companies direct control over their data.
• Offers hosted services to a limited number of people behind
firewall, so it minimizes the security concerns.

Public Cloud
• It helps you leverage the best of both worlds
• A cloud computing environment which uses a mix of on-
premises, private cloud and third-party, public cloud services

What is AWS?

12. www.edureka.co/cloudcomputingEDUREKA AWS ARCHITECT CERTIFICATION TRAINING
What is AWS?
Amazon Web Services (AWS) is a secure cloud services platform, offering compute power, database
storage, content delivery and other functionality to help businesses scale and grow.
Having said that, let’s take a broader look at what AWS is, and see which Service Model it fits in.

AWS IaaS
AWS, is an IaaS because it provides infrastructure in the form of its AWS services
For example,
EC2

18. www.edureka.co/cloudcomputingEDUREKA AWS ARCHITECT CERTIFICATION TRAINING
AWS PaaS
It is a PaaS because it allows you to focus on deployment and management of your applications
For example,
Elastic Beanstalk

19. www.edureka.co/cloudcomputingEDUREKA AWS ARCHITECT CERTIFICATION TRAINING
AWS SaaS
It is not a SaaS in itself, but it provides a marketplace where you can discover and subscribe
to dozens of SaaS and API products
For example,
AWS MarketPlace

How do services interact in the Amazon Cloud?

21. www.edureka.co/cloudcomputingEDUREKA AWS ARCHITECT CERTIFICATION TRAINING
How do services interact in the Amazon Cloud?
In AWS, you use various services which work together to form an application. But how do
these services interact with each other?
VPC AWS
Using VPC you can control the following things:
• Internet Access to your instances
• Communication between each of your instances
• Isolating your resources from the rest of AWS
VPC
Elastic Beanstalk
RDS
