OPENSTACK

Open source cloud computing platform for building massively

scalable clouds.

Open source system for automating deployment,

scaling and management of containerized applications.

Provides framework for building distributed platforms.

KUBERNETES

An integrated infrastructure platform to run, orchestrate,

monitor and scale containers. Built around Kubernetes and

Docker.

APPLICATION CONTAINERS

1. Code: mysqld

2. Configuration: /etc/my.cnf

3. Data: /var/lib/mysql

4. Other stuff :-)

CURRENT STATE

● Orchestration and auto-scaling via Heat templates and Ceilometer

● Block Storage via Cinder volumes.

● Networking via Neutron networks.

● Load Balancing via Neutron LBaaS

● Compute via Nova virtual machines.

IDEAL STATE (ROADMAP)

● Networking integration via Kuryr

● Re-validate architecture on bare-metal using Ironic

● DNS via Designate● Load Balancing via Octavia

(LBaaS V2)● File Storage via Manila

TAKEAWAYS

● OpenStack enables operations to expose resources● OpenShift, built on Kubernetes, enables developers to consume resources and manage

their application life-cycle.● OpenShift + OpenStack = Distributed Systems Operating System
