Three key points about the document: 1) It provides an overview of public cloud providers like Amazon Web Services (AWS), describing some of its core services like EC2, S3, and EBS. 2) It also discusses private cloud platforms like OpenStack and key concepts in private clouds around virtual machines, images, provisioning, auditing and monitoring. 3) The document outlines some of the core components of OpenStack including Compute, Storage, Image Service, Dashboard and Identity Management and how they help manage instances, storage and user access in a private cloud.

4. Our Coverage
Public Cloud – IaaS & PaaS
Private Cloud

5. Public Cloud Providers

6. Amazon Web Services - IaaS
All Services are pay-as-you-go billed
monthly based on monthly usage.
EC2 - Provides resizable compute facility
on top of Amazon cloud.
EBS – Block Level storage like online NAS
for EC2 particularly for database, file system
S3 - Store and retrieve objects
Cloud Front – low latency content distribution

7. Other Stuff
Amazon Elastic MapReduce
Amazon Auto Scaling
Elastic Load Balancing
Amazon Virtual Private Cloud
Dynamo db, Simple db – No SQL
Amazon RDS - RDBMS

8. Setup Accessible Protocols

9. AMI Manager

10. Launch an Instance

11. Launch an Instance

12. Connecting to Instance
Download a shell client like Putty
Login via ssh using the pem
(privacy enhanced mail) key pair
ssh -i xxx-keypair root@ec2-XXX-XXX-XXX-XXX.z-2.compute-1.amazonaws.com


13. Terminating an Instance

14. Creating Own AMIs
S3 Bucket – to save the AMI as an object
Bundling – taking a snapshot of the file
system so it can be booted and modified.

15. Bundle an Image

16. Sending the Bundle to an S3 Bucket

17. Bundle tasks

18. Registering the Image

19. Electronic Block Storage
Block Level Storage for EC2
Can be provisioned for other AWS services
ISCSI disk – internet SCSI
EBS Volume
EBS Snapshot

20. Create an EBS Volume

21. Attach Volume to an Instance

22. EBS Snapshot

23. Detatching a Volume

24. Deleting a Volume

25. Deleting a Snapshot

26. Elastic IPs
Elastic IPs are associated with AWS
account not instances.
Elastic IP addresses allow you to
mask your instance

27. Creating a new EIP

28. Associate it to an Instance

29. Private Cloud Providers

30. Terminology
Hypervisors – Virtual Machine
Images – OS instances residing on hypervisors
Provisioning – deployment strategy for applications
Auditing – Security, Bandwidth , Usage
Monitoring – Managing cluster health
Metering – Bandwidth , Cost of Running an instance
Orchestration – Automatic Arrangement and
Coordination of resources

31. OpenStack - components
 Compute(nova) – Cloud Fabric Controller
 Storage(swift) – Redundant Storage Service
 Image Service(glance) – Registration and
Provisioning of Disk images
 Dashboard (horizon) – Manage images and
lifecycle of instances
 Identity Management(keystone) –
Policy, Token and Catalog

33. Dashboard

34. Role Based Auth
Tenants – Tenants are projects for Consumers
or Customers
Users – Users can be part of multiple tenants
Roles – role based authentication & access
Tokens – authenticaiton tokens

35. Flavours
Available Hardware configurations
for each server
Diskspace, Memory, I/O level definition


36. Services
Shared Services Across various
OpenStack Instances
Identity Service
Image Service
Available to nova, swift

37. Uses
Secure In-firewall usage for
insfrastructure for Banks, financial
institutions
Best use of existing hardware
