7 - Introduction to OpenStack & SDN by Ady Saputra
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.” — NIST
Cloud Computing : Essential Characteristic  On-demand self-service  Rapid elasticity  Ubiquitous network access  Resource pooling  Measured service
Cloud Computing : Delivery Model Openstack technology 101, Boston OpenStack Meet-up, Feb 19, 2014
Cloud Computing : Deployment Models  Public cloud  Private cloud  Community cloud  Hybrid cloud
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
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
Openstack : Release History  Austin : Oct 2010  Bexar : Feb 2011  Cactus : April 2011  Diablo : Sept 2011  Essex : April 2012  Folsom : Sept 2012  Grizzly : April 2013  Havana : Oct 2013  Icehouse : April 2014  Juno : Oct 2014  Kilo : April 2015
Openstack : Architecture Neutron Cinder Horizon Nova keystone Glance Swift
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.
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, ...)
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
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
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 ?
OpenStack & SDN SDN controllers with OpenStack : Controller on every compute node SDN controller with OpenStack : Centralized controller model
How to deploy  Public Clouds  Cloudwatt, DreamCompute, eNocloud, HP, Rackspace.  Local Dev Environment  http://devstack.org/  distributions powered by OpenStack  Cloudscaling, Debian, Fedora, Piston Cloud Computing, RedHat, SwiftStack, SUSE, Ubuntu, Stackops  build from scratch
 OpenStack Compute (nova): https://launchpad.net/nova  OpenStack Object Storage (swift): https://launchpad.net/swift  OpenStack Image Service (glance): https://launchpad.net/glance  OpenStack Identity (keystone): https://launchpad.net/keystone  OpenStack Dashboard (horizon): https://launchpad.net/horizon  OpenStack Networking (Neutron): https://launchpad.net/Neutron  OpenStack Block Storage service (cinder): https://launchpad.net/cinder  Ceilometer: https://launchpad.net/ceilometer  Heat: https://launchpad.net/heat  Database Service (Trove) - Scalable and reliable Cloud Database as a Service provisioning functionality for both relational and non-relational database engines  Bare Metal (Ironic) - Provides an API for management and provisioning of physical machines.  Queue Service (Marconi) - message queueing API and service for distributed application messaging  Data Processing (Savannah) – Hadoop on OpenStack
