Session Objectives

•  Introduction to Openstack

• Openstack Architecture

• Openstack Use case & challenges

• Closing Thoughts


What Is OpenStack?

OpenStack is both Software and a Community

5


What Problem Does OpenStack Solve?

OpenStack provides a framework for building elastic cloud infrastructure at massive scale.

✦Facilitates management of

✦COMPUTE, ✦NETWORK, and

✦STORAGE resources

✦Provides natural infrastructure for elastic applications

6


OpenStack Components Provide..

✦Compute ✦Virtual machine management

hypervisor support ✦Comprehensive ✦Networks

✦IP address management

✦Security ✦Storage

✦Volumes

services (block storage)

✦Object storage for VM images and files

7


OpenStack as Community

Technical Committee - defines and stewards technical direction Board of Directors - provides strategic and financial oversight of

Foundation Resources User Committee - created to represent enterprise, academic and

service provider users

Openstack Deployment Challenges

51

• Personal Skills • Linux, Cloud Infrastructure & Openstack architecture

• Tweaking of devstack is needed at some cases where the general code is unable to cater user’s requirement.

• Security concern in Openstack deployment • Getting operation, network & system engineering team

to understand openstack & familiarize with it. • How about IPv6 services ? • How about Service Load balancer, VPN, Firewall ?
