4. Pros & Cons
Generic Hosting
• Simple / Easy
– start & Use
– Cost Calculation
– Configuration
– Administration
• Pain
– Scale as you grow
– Add more
– Handle Failures
AWS Hosting
• Complex
– To start & Use
– Understand Cost
– Administer / Configure
• Benefits
– Scale as you grow
– Ease Add / Remove
– Handle Failures
– Ready for future

6. • EC2  A computer given to you with full
access, but located at AWS Data Centre
• Like your computer it comes in different CPU
types, memory, hard disk options.
• It comes pre-loaded with an OS, you get to
pick the OS you need.
• Work on the EC2 Instance like you work on a
remote server with full access (Login using
SSH/RDP)

7. Other components with EC2
AMI  Amazon Machine Image
EBS  Elastic Block Storage (Network Drive)
Elastic Ip  IP Address for your machine
Security group  Network Firewall (Not M/C)
CloudWatch  Performance Numbers
ELB  Elastic Load balancing
Takes multiple requests on internet and transfers then to
different servers & Vise-Versa for the responses

8. What Can I do with Ec2
• Install, configure and execute any software of
your choice.
– Web Server, File Server, DB Server, CRM, etc
– Backend Video Post Processing, Audio Post
Processing, Data Analysis
– Email Server, FTP Server etc

9. So what it costs me?
• It costs per every hour of usage
– Start an instance and the $$$ clock starts
– Stop an instance the $$$ clock stops
– Re-start an instance the $$$ clock start again
– Terminate the instance the $$$ clock stops
• There are three Rate Slabs in EC2
– Spot instance (AWS can take it back any time! Costs you super
low rate per hour)
– On Demand instance (Will never be taken back till you give it
back! Comes with a price)
– Reserved instance (Pay upfront and commit to use it in 12
months. Similar to On-Deman but per hour rates are lower)

10. Workshop
• Let us quickly create an AWS Instance and play
with it!

11. • S3  Network Storage Device Located in AWS
Datacentre.
• You can access it using an URL like any network device.
• Store files, static web sites, images, videos, CSS, etc.
• Dump logs
• CloudFront  S3*Many!
• CloudFront is the Content Delivery Network that
delivers S3 Data to various caching servers around the
globe for faster access in that region.

12. What Can I do with S3
• Use it as your Static Web Site Hosting Provide.
• Use it along with CloudFront for faster delivery
of static content.
• Use it for archiving data for safe storage
(Highly reliable)
• Provide Conditional access like Protected
Profile info

13. So what it costs me?
• S3 is charged based on the amount of data
you store and the amount of data you
transfer in/out
• CloudFront is charged on the amount of data
you transfer in/out.

14. Workshop
• Let us quickly create S3 Buckets and put
content in it.
• Let us also put static web site in it

15. • RDS  C-Panel kind of MySQL Data Base
Server.
• RDS Also support MSSQL, Oracle Servers
• Advanced capabilities of RDS are
– Support for Multi ZONE (Scale up)
– Support for AutoBack up and restore
– Reliable DB Option

16. So what it costs me?
• RDS comes in different configurtions like EC2
– Based on the server configuration you pay
– Based on the DB Option you pay
– Based on the Multi Zone Support (One live Server
and one Standby Server), you pay.

17. Workshop
• Let us quickly create RDS Instance.
