NIST Definition of Cloud Computing September 2011 http://csrc.nist.gov/publications/PubsSPs.html#800-145

Cloud computing is a model for enabling convenient, on-demand

network access to a shared pool of configurable computing resources

(e.g., networks, servers, storage, applications, and services) that can be

rapidly provisioned and released with minimal management effort or

service provider interaction.

This cloud model promotes availability and is composed of:

Source: NIST Definition of Cloud Computing v15

3 Service Models

• SaaS: Software as a Service

• PaaS: Platform as a Service

• IaaS: Infrastructure as a Service

4 Deployment Models

• Public Cloud • Community Cloud • Private Cloud • Hybrid Cloud

5 Essential Characteristics

• On-demand self-service • Broad network access • Resource pooling • Rapid elasticity • Measured service

What is OpenStack? Open source software for managing private and public clouds

• A set of distributed services which control compute, storage, network, identity management, orchestration, and much more

– Open source • Governed by Apache 2.0 License

– Driven by a global community

– 6 month release cycle

• Initial focus on Iaas, evolving into PaaS and SaaS

• Single management dashboard

• Open standardized API’s

17


OpenStack - Modular Architecture

• Web portal / dashboard for cloud admins and self-service users

• Cloud services exposed through APIs

• CLI, Python libraries, ...

• Interoperating services with REST APIs

Additionally Required Infrastructure Services Inter-Service Communication und Persistence

• Between services themselves, RPC calls are performed using the Advanced Message Queuing Protocol (AMQP)

– OpenStack services use a messaging broker to rendezvous with another • OpenStack can be configured for Rabbit MQ (most often) or the Apache QPid broker

• MySQL is the default detabase server used by many OpenStack services

– MongoDB is the recommended storage backend for Ceilometer • May alternatively use MySQL or any other SQLAlchemy-supported DB like PostgreSQL

– SQLAlchemy is a Python SQL toolkit and Object Relational Mapper
