The document introduces OpenStack and its integration with Software-Defined Networking (SDN), discussing its architecture, deployment models, and features. It emphasizes OpenStack as an open-source cloud operating system capable of managing large pools of compute, storage, and networking resources, supporting various cloud deployment options. The outline covers topics like cloud computing definitions, OpenStack's components, release history, and advantages of utilizing SDN within OpenStack environments.
![Cloud Computing :
Definition
“Cloud computing is a model for enabling
ubiquitous, convenient, on-demand network
access to a shared pool of configurable
computing resources [...] that can be rapidly
provisioned and released with minimal
management effort or service provider
interaction.”

- 10. Openstack “OpenStack is a cloud operating system that controls large pools of compute, storage, and networking resources throughout a data center, all managed through a dashboard that gives administrators control while empowering users to provision resources through a web interface.” — OpenStack Foundation
- 11. OpenStack : Feature Open source software for building private and public clouds Designed for flexibility and many different use cases Mix and match components Kit of administrative tools Enables multi-tenancy Quota for different users Users can be associated with multiple tenants Provides virtual machines (VM) on demand Self service provisioning Snapshotting capability Storage volumes Block storage for VM images Object storage for VM images and arbitrary files

- 13. Openstack : Architecture Neutron Cinder Horizon Nova keystone Glance Swift
- 14. Openstack : Architecture Compute "Nova” provides virtual servers resource (CPU, RAM, etc) on demand. Image "Glance” provides a catalog and repository for virtual disk images. Dashboard "Horizon” provides a modular web-based user interface for all the OpenStack services. Used to perform most operations like launching an instance, assigning IP addresses and setting access controls. Identity "Keystone” provides authentication and authorization for all the OpenStack services. It also provides a service catalog of services within a particular OpenStack cloud. Object Store "Swift” provides object storage. It allows you to store or retrieve files (but not mount directories like a fileserver). Block Storage "Cinder” provides persistent block storage to guest VMs. Network “Neutron” provides "network connectivity as a service" between interface devices managed by other OpenStack services.
- 15. OpenStack : Neutron Provide Network-as-a-Service (NaaS) Allowing tenants to control their own private networks Ability to create “multi-tier” networks Control IP addressing (IP address overlapping) Neutron API for operating logical networks Separate logical operations and backend provisioning Backend technologies are provisioned/configured by Neutron plugins/drivers Support multiple emerging network technologies New requirements never before in cloud data centers Multi tenancy, remote data center, VM mobility, advanced network services, ... Nova provides only legacy basic technology (VLAN + iptables) Needs new architecture/framework to support emerging network technologies SDN/OpenFlow-based network Overlay tunneling (VXLAN, NVGRE, STT, ...) L2 Fabric (Fabric Path, QFabric, ...)
- 16. Neutron Component Neutron Server • Runs on Controller node. • Exposes API. Enforces network model. • Passes requests to Neutron plugin. Neutron Plugin • Runs on Controller node. • Implements the API. • Interacts with neutron server, database and agents. Queue • Enhance communication between each components of neutron Database • Persistent network model Plugin agent (*) • Run on each compute node • Connect instances to network port DHCP Agent (*) • Start/stop dhcp server • Maintain dhcp configuration L3 Agent (*) • To implement floating IPs and other L3 features, such as NAT
- 17. Neutron ML2 Plugin Allowing OpenStack to utilize variety of layer 2 networking technologies found in complex real data-center OVS / Linux Bridge plugins will be removed in the near future We can use multiple network technologies at the same time Type Driver Manages logical network resources depending on “network type” (e.g., VLAN-ID) Support local, flat, vlan, gre & vxlan network type Mechanism Driver : Configures/provisions network devices Open vSwitch agent driver, Linux Bridge agent driver, OpenFlow Agent driver Cisco Nexus 1000V driver, Arista driver
- 18. Neutron advantages Advance Network Service LBaaS, FWaaS, VPNaaS, etc. Provide additional network features rather than simple data transfer (L2/L3) Would like to insert such network services on demand. Use network services in “Cloud” style (through API and on demand) It fits into SDN. NFV support ?
