cloud technology stack comparison (openstack) - cloud connect chicago 2012
DESCRIPTION
Cloud orchestration stacks are an important component in completing the move to a private cloud. In this rapid fire session, speakers representing key cloud orchestration stacks will have 10 minutes each to present their responses to key questions about the functions, features and capabilities of each cloud stack. Questions include: services and capabilities offered; languages, operating systems, APIs and image formats supported; virtualization stacks supported; management tools; portability; hardware, capacity, performance and availability constraints, pricing and more. Presentations will be followed by an open Q and A discussion. This presentation covers the OpenStack cloud stack.TRANSCRIPT

What standards or de-facto standards does it support?
• OpenStack API– Open API built by the community. Technical
meritocracy determines how it is constructed and how it should be implemented.
• EC2 API via euca2ools– Mandatory for some business models, offered as
an elective service for maximum coverage.
• http://wiki.openstack.org/Nova/APIFeatureComparison
• Open SDKs– Community support around OpenStack and EC2
API

Capacity, performance, availability• What are the capacity, performance, and availability constraints?
– Horizontally & massively scalable
• Some of the largest deployments are thousands of nodes large
• Hypervisor agnostic – more hypervisors being added each release
• What high availability features are available to eliminate any single points of failure?– Modular Services
• API
• Compute
• Network
• Schedule
• Object Storage
• Block Storage
• Scheduler
