5. Public Cloud vs. Private Cloud
• Private Cloud is a Cloud Computing platform
within a company’s firewall and physical
boundaries
• Private Clouds try to offer the same features
and benefits of public cloud systems, while
removing a number of objections to the Cloud
Computing model
• Control over enterprise and customer data
• Worries about security
• Issues connected to regulatory compliance

6. Public Cloud vs. Private Cloud (2)
• Private Clouds don’t get the same level of
elasticity because of the lack of scale
• AWS does not offer a Private Cloud service
• AWS offers a Virtual Private Cloud (VPC)
service
• VPC lacks physical separation

7. Security
• #1 concern for enterprises to move to Public Cloud
• #1 priority of AWS
• Security is shared responsibility of AWS and
customer
• AWS provides physical security and security upto the
operating system level
• Customer to ensure that the EC2 instances and
applications are secure
• AWS physical security better than the largest enterprises.
AWS datacenters have several security certifications.

8. AWS Best Practices
• To get the most out of AWS, one
needs to think a little differently when
hosting the applications on AWS
• To get the most out of AWS, one
should use AWS building blocks as
much as possible

9. AWS Best Practices List (1)
• Use Elastic Block Store (EBS) as root volume of
EC2 instances
• Use Elastic Load Balancer (ELB) for load
balancing between EC2 instances
• Use Auto Scaling for automatically scaling EC2
instances depending on load
• Replicate the application stack in at least 2
Availability Zones (AZ) in an active-active setup

10. AWS Best Practices List (2)
• Backup data to a different region for
disaster recovery purpose
• Use S3 for static content or large data that
needs to be shared across EC2 instances
• Use CloudFront for edge caching the high
volume content

11. AWS Best Practices List (3)
• Use Replicated Database Service (RDS) to
manage database aspects such as replicas
and backup
• Use provisioned ops option in Replicated
Database Service (RDS) and DynamoDB
for high performance database access
