OpenStack journey from Folsom to Grizzly

Srinivasa Acharya

Agenda

• Openstack and release timelines• Folsom features• Folsom Architecture• Folsom request flow• Grizzly Themes and work areas

Openstack – www.openstack.org

OpenStack is a Open source cloud operating system that •Controls large pools of compute, storage, and networking resources throughout a datacenter•Resources managed through a dashboard that gives administrators control •Empowering their users to provision resources through a web interface.

Why Openstack?• Dynamic community & ecosystem• Open, web-based API• Highly Scalable• Flexible, plug-in technology to accelerate time-to-market

Project Name No . of Blue PrintsCompute - NOVA 48Object Storage - SWIFT 10Image Service - GLANCE 25Identity management - KEYSTONE 8Dashboard - HORIZON 31Network Service - QUANTUM 42Block Storage - CINDER 13

Focus on•Usability and deployability improvements•Hardening of Nova•Security Enhancements – Sec groups, RBAC, trusted messaging etc•Decoupling Network and Volume from Nova – Quantum and Cinder

General user/admin experience improvements

• More consistent CLI• Robust Dashboard with Quantum/Cinder support • Nova Hardening – Instance status tracking

improvements• Robust networking Model– Create and maintain n/w in Horizon– Create virtual ports and routers

• Glance image manipulation in Horizon• New Hypervisors support – Hyper-V

New Network Service -Quantum• Provide a rich and tenant-facing API for defining network connectivity and addressing in

the cloud.• Gives the operators the ability to leverage different networking technologies to power

their cloud networking. Available Plug-ins•Linux Bridge•NICIRA NVP•OpenVSwitch•CISCO( UCS Blade+Nexus)•Ryu Openflow Controller•NEC ProgrammableFlow Controller

Quantum Architecture

Feature Nova-Network

Quantum

Multi-Host Yes No

VLAN N/w Yes Yes

Flat(DHCP) n/w Yes Yes

Tunneling(GRE) No Yes

Multi Bridge No Yes

SDN No Yes

IPAM Yes Yes

Dashboard Support No Limited- No floating IPs

Security Groups Yes Limited – Only with non-overlapping IP pools

New Volume Service- Cinder•Started with nova volume code base, but a separate project•Consistent with decoupling non compute services from Nova•Provide rich set of Volume APIs•Has own scheduler and ability for multiple volume plug-ins

New features:Volume from glance ImagesStorage backend:Netapp /w NFSZadara VPSA

Cinder Architecture

Nova Improvement and features• Block Live migrations – Xen, KVM• Improved XenAPI Support– Boot from Volume– Live migration

• Better Instance state tracking• New Hypervisor Drivers

• Hyper-V back in Openstack• LPAR driver- IBM

• Project Specific Instance Flavors• Nova API Scalability• Placement of Instances on LVMs

Folsom Conceptual Architecture

Folsom Logical Architecture
