What is Cloud?

OpenStack 1013

Cloud is more than virtualization

• Virtualization is an integral part of cloud computing

– Virtualization allows to fully maximize the computing resources but it still requires a system administrator to provision the virtual machine for the end-users

– Virtualization itself does not provide the customer a self-service layer and without that layer you cannot deliver compute as a service.

• Cloud computing is about providing self-service to end users

– Architecture and tools to enable virtualization to be delivered as a service and virtualization is one possible service that could be delivered.

– Self-provision servers, applications and other resources

– Utility model similar to power or water – meter resources and pay for what is used

What is OpenStack?

As described by the OpenStack Foundation:

“Open source software for creating

private and public clouds.”

OpenStack 1016

Why OpenStack?

• Standard– OpenStack is not a “cheap alternative” to proprietary, it is a dominant

standard as an IaaS.

• Compatible– Compatibility with public cloud makes it easy to migrate data and

applications to public/hybrid clouds.

• Proven– OpenStack today powers some of the largest public and private clouds in

the world.

How to provision a VM in your OpenStack development environment?

OpenStack 10132

Launch a VM

OpenStack 10133

• Set environment:

– export OS_AUTH_URL=https://keystone.ash2.symcpe.net/v3

– export OS_USERNAME=priti_desai

– export OS_PASSWORD=<password>

– export OS_USER_DOMAIN_NAME=<domain name>

– export OS_PROJECT_DOMAIN_NAME=<domain name>

– export OS_PROJECT_NAME=<project name>

– export OS_IDENTITY_API_VERSION=3

Launch a VM

• Choose flavor:– openstack flavor list

• Choose Image:– openstack image list

• Choose Network:– openstack network show <private-network>

• Choose Security Group:– openstack security group list

• Create a VM– openstack server create –flavor=<flavor-id> –image=<image-id> --min=1 --max=1 --nic net-id=<net-id>--

security-group=<security-group> openstack-test-server

OpenStack 10134

Access VM

• List VM– openstack server list

• Create Floating IP– openstack ip floating create <public-network>

• Attach floating IP– openstack ip floating add <floating IP> <server>

• Logging into VM– Ping <floating IP>

– ssh root@<floating IP>
