OpenStack is an open source cloud computing platform that provides infrastructure as a service. It allows users to provision compute, storage, and networking resources on demand in a self-service manner similar to public cloud offerings. OpenStack is modular and scalable, with components that can be customized or replaced as needed. Key components include compute (Nova), storage (Cinder, Swift, Glance), networking (Neutron), identity (Keystone), dashboard (Horizon), telemetry (Ceilometer), and orchestration (Heat). Red Hat provides commercial support for OpenStack through its Red Hat Enterprise Linux OpenStack Platform.

Visão Técnica

3. POR QUE OPENSTACK ?
● Traz recursos de cloud como públicas em seu datacenter
● Fornece grande escalabilidade sob demanda
– 1,000's → 10,000's de VM's
● É Aberto!
– Fornece flexibilidade para customizar e interagir
● Desenvolvimento Aberto = maior interação “velocidade de features”
– Features e Funções para atender a sua demanda, mais rápido ao
mercado sobre o software proprietário

4. O QUE É OPENSTACK?

5. OPENSTACK
CLOUD INFRAESRTUTURA
● Arquitetura modular
● Desenhado para escalar facilmente
● Baseado em módulos independentes

6. O OPENSTACK É UM
“SISTEMA OPERACIONAL DE
CLOUD” ?

7. OPENSTACK
● Precisa acessar os recursos de hardware x86
● Precisa de um ambiente operacional, hypervisor, serviços
● Aproveita bibliotecas de código existente para a
funcionalidade

OpenStack Components: Block/Volume Storage (“Cinder”)AMQPMessageBus
* No automatic zoning support for Fibre Channel. Individual vendor FC drivers might have additional constraints

21. Block Storage (Volume) Service (Cinder)
● Provides block storage for virtual machines (persistent disks).
● Similar to Amazon EBS service.
● Plug-in architecture for vendor extensions, e.g. NetApp driver for
Cinder.

28. Monitoring and Metering (Ceilometer)
● Single infrastructure for collecting measurements from
an entire OpenStack infrastructure.
● Eliminates the need for multiple agents attaching directly to each
OpenStack service.
● Targets monitoring and metering but is expandable to collect for
other
● use cases.
