Who are these Chaps talking to us ?● Ritesh Nanda (Cloud Architect at Ericsson responsible for Enterprise Cloud Program/Data Centre Operations).● Syed Armani (Contributer at OpenStack and Google OpenSource programmes.)
Why these Chaps are here?● Mainly to talk about OpenStack based clouds, OpenStack Foundation and Quantum.● Current state and future developments in OpenStack ecosystem.
Road to the OpenStack Foundation October 2011 April 2012 July 18, 2012 Sept 19, 2012 19 companies Final legal Announced plans announce support for OpenStack to launch documents Foundation; form posted for Foundation independent Foundation in 2012 Drafting Committee ratification Launch!

It is a software which delivers massively scalable private and public clouds.

KeystoneKeystone is an authentication framework for OpenStack. It provides theability to add users to groups (also known as tenants) and to managepermissions between users and groups. Permissions include the abilityto launch and terminate instances or to administer everyone’s instance.
NOVA Nova is the brain of OpenStack based clouds. It handleslaunching, networking, maintaining, storage and terminating of virtual machines. Nova has several sub components.
Subcomponents of Novanova-api: Accepts incoming commands to interact with the OpenStack cloud.nova-cert: Manages SSL certificates.nova-compute: Manages the actual virtual machines.nova-consoleauth: Manages authentication for VNC access to the instances.nova-network: Manages the OpenStack network system.nova-objectstore: Provides a very basic object storage system.nova-scheduler: Schedules actions between nova-api and other components.nova-volume: Manages storage volumes for instances to attach and use.
GlanceGlance provides a catalogue of images. “Images” in this case canbe thought of as a virtual machine template. When launching aninstance in OpenStack, you choose a template from Glance, suchas Ubuntu 12.04 or Centos 5.8, and then OpenStack creates yourinstance based on that template.
SwiftSwift is a very robust object storage system that canmanage petabytes of data spread across severalservers.
HorizonHorizon is a web-based interface to OpenStack. The OpenStackdashboard provides administrators and users a graphical interface toaccess, provision and automate cloud-based resources. The extensibledesign makes it easy to plug in and expose third party products andservices, such as billing, monitoring and additional management tools.

Continue ... ● A compute agent runs on each compute node and polls for resource utilization statistics. There may be other types of agents in the future. ● A central agent runs on a central management server to poll for resource utilization statistics for resources not tied to instances or compute nodes. ● A collector runs on one or more central management servers to monitor the message queues (for notifications and for metering data coming from the agent). ● Notification messages are processed and turned into metering messages and sent back out onto the message bus using the appropriate topic. Metering messages are written to the data store without modification. ● A data store is a database capable of handling concurrent writes (from one or more collector instances) and reads (from the API server). ● An API server runs on one or more central management servers to provide access to the data from the data store.
QuantumQuantum is an OpenStack project to provide "networkconnectivity as a service" between interface devices(e.g., vNICs) managed by other OpenStack services(e.g., nova).
Why Network as a ServiceVirtualization : It’s in the network too!Server Don’t sleep at night but Application and Admins Do!
Network as a ServiceMultiple network per tenantMultiple network interfaces per VMAbility to connect networks to VM network interfacesIsolation b/w networksControl over IP addressingAPI for network ManagementAvoid lock in to a specific vendor technology or SolutionNetwork Infrastructure , but Virtual

What they say about QuantumQuantum to provide network connectivity as a Service b/w interfaces devices (eg-Vnics) managed by other Openstack Services e.g.(nova) Source:wiki.openstack.org/QuantumProvides a “building Block ” for Sophisticated cloud network topologies @danwendlandt@PTL for Quantum

Why Melange??IPAM management currently done by novaWill decouple Dhcp/dnsmasq functionalityStandlone service with it’s own API
What Melange Provides• IPAM Service IP address management• Enable network block subdivision• VM discovery/auto-assignment• Consumer of IPAM services are expected to be other Openstack Services i.e. LBaas etc.• Private (overlapping) address space i.e. VPN• Store ip address, gateway, subnet, DNS, NTP etc.• Floating IP support.
ConclusionOpenStack is the future of open clouds. They saythat OpenStack is kernel for cloud operatingsystems. It fits very well for Private, Public andHybrid cloud. Enterprises like HP and IBM havestarted adapting to provide enterprise servicesbased on top of OpenStack.
