The document is a presentation by Bhuvaneswari Subramani on cloud computing and AWS, covering the fundamentals of cloud services, AWS core services, and the benefits of using AWS. It highlights the different cloud computing models (SaaS, PaaS, IaaS), the advantages of AWS including scalability and cost-efficiency, and provides insights on getting started with AWS through free tier options and educational resources. Additionally, it discusses AWS core services such as EC2, VPC, S3, RDS, and IAM along with best practices for security and resource management.

Intro to cloudComputing

5. Cloud computing is on-demand delivery of IT
resources and applications via the Internet with
pay-as-you-go pricing.
What is Cloud Computing?

6. SaaS
PaaS
IaaS
Cloud Computing Model
SaaS: Software as a Service
Provides applications to the end user.
Applications
Ex: gmail, google docs, MS Office 365, Slack, Dropbox
PaaS: Platform as a Service
Provides developers with resources that enable them to create applications.
Ex: AWS Elastic Beasnstalk, Amazon RDS, Amazon Aurora
IaaS: Infrastructure as a Service
The cloud is replacing the user’s need for some physical resource.
Ex: AWS EC2, Google Compute Engine

7. A hybrid deployment is a
way to connect
infrastructure and
applications between
cloud-based resources
and existing resources
that are not located in
the cloud.

self-service
In 2003, Amazon.com’s monolithic e-commerce app reached critical mass.
To gain agility, a significant investment in Service Oriented Architecture (SOA)
refactoring was clearly needed. DevOps culture needed too. Amazon
reorganized, and retooled …
Amazon network engineers Benjamin Black and Chris Pinkham (and others)
wrote an internal proposal (a “narrative”) describing the foundational IaaS
services
Jeff Bezos supported the narrative and envisioned anyone, such as college kids
in a dorm room, could use such a platform to start a new company!
AWS launched in 2006. Key decision:Treat Amazon.com like any other customer.
How AWS began

11. Advantages and Benefits of AWS Cloud Computing
Trade capital expense
for variable expense.
Benefit from massive
economies of scale.
Stop guessing
capacity.
Go global in minutes.
Increase speed and
agility.
Stop spending money on
running and maintaining
data centers.

12. Global AWS Infrastructure
The AWS Cloud spans 81 Availability Zones within 25 geographic regions around the world,
with announced plans for 24 more Availability Zones and 8 more AWS Regions in Australia,
India, Indonesia, Israel, New Zealand, Spain, Switzerland, and United Arab Emirates (UAE).
*as on Oct 2021

13. AWSRegion >

Datacenters
Regional Resiliency in AWS
AWS and its customers achieve high resiliency by placing redundant
infrastructure in at least 3 Availability Zones
“Multi-AZ” services in AWS have multi-datacenter diversity,
redundancy, and automatic failover across datacenters.

IAM Best Practices
• Users – Create Individual Users
• Permissions – Grant least privilege
• Groups – Manage permissions with groups
• Conditions – Restrict privileged access further
• Auditing – Enable AWS CloudTrail to get log of API calls.
• Password – Configure a strong password policy
• MFA – Enable MFA for privileged users
• Sharing – Use IAM roles to share access
• Roles – Use IAM roles for Amazon EC2 instances
• Root – Reduce or remove use of root.
