OpenStack is an open-source cloud computing platform that provides common services for public and private clouds. It controls large pools of compute, storage, and networking resources throughout a datacenter, managed through a dashboard or via APIs. OpenStack works through a combination of interrelated components that offer services for controlling large pools of compute, storage, and networking resources throughout a datacenter, managed through a dashboard or via APIs. Some common OpenStack components include Nova for compute resources, Swift for object storage, and Neutron for networking.

1. Introduction to Openstack

2. • Cloud + Computing
• Cloud is synonym for Internet
• Cloud computing is a type of computing that relies on sharing computing
resources rather than having local servers or personal devices to handle
applications.
• It’s a kind of computing where different services – (storage, servers,
networks, applications) are provided over the internet to organizations.
What is Cloud Computing?

3. Public Cloud Private Cloud
Owned by the primary vendor and not by the
consumer/customer.
Managed by the users working within the
organization.
Unlimited Resources. Limited Resources.
Data security risks are more. Geographical
location of data is unknown.
Data security risks are less. Geographical
location of data is known in case of private
cloud.
SLA’s does not guarantee 100% ownership of
cloud services provided.
Since its own private setup, full ownership is
available.
Public clouds support more number of
different roles/services.
Private clouds support less number of
different roles/services.
Fast provisioning/allocation of resources as
billing is as per usage.
Slow provisioning/allocation of resources as
first requirement-analysis is done and later
the request is forwarded/approved.
Public vs Private Cloud
