An overview of the cloud landscape and OpenStack as a basic component for programmable infrastructure among so many modern open-source technologies.

1. Athens OpenStack User Group #OSATH

2. Outline
• Cloud and automation
• OpenStack cloud solution
• brief – How to start designing a cloud
• #OSATH, local OpenStack community

3. Automation makes the cloud
to enable ad-hoc and elastic access to computing resources

4. On the cloud …
• IT resources provisioning
• Platform and stack deployment
• Software delivery
… are faster
and easier …
• Software and system updates
• Operations monitoring
• Experimenting in new ideas

5. Automation is accomplished with many players in the game
• Virtualization
– KVM, OVS, docker
– and more
• Scale-out Storage
– Ceph, Glusterfs
– and more
• Orchestration and lifecycle management
– Ansible, Puppet, Terraform and more
– OpenStack, Kubernetes, swarm
… it ’s a collaboration

6. OpenStack exposes API set
to automate all IT infrastructure management service

7. Architecture Overview

14. Think BIG, start small
to validate new processes around the IT services
and scale smoothly while the demand grows

15. Guidelines to design
• Account for services to offer
• Learn with PoC
• Test with other stakeholder – e.g. developers
• Realize benefits and measure success
• Prepare for administrative – process change

16. Tip: improve everything
Plan
• Design solution
• Schedule steps
• Evaluate design
based on analyse
stage feedback
Implement
• Automate tasks
• Deploy services
• Configure systems
• Maintain with backups
and upgrades
Analyse
• Monitor
• Troubleshoot
• Feedback to
Planning stage
… take that as Principle
