OpenStack is an open source cloud computing platform providing infrastructure as a service (IaaS). The presentation will encapsulate the contents of OpenStack, amplified by practical demo and simple but effective guidelines to access OpenStack. ——— Speaker: Chi Le – Head of Infrastructure System at Da Nang ICT Infrastructure Development Center

7. Enterprises are building clouds to...
Where is your enterprise on the path to cloud?
Meet departmental resource needs & timelines
Control & monitor the entire environment
2. Cloud Data Center 3. Cloud Federation1. Virtualization

8. Datacenters are being virtualized, Servers are first
Hypervisors provide abstraction between SW and HW (Servers)
HOST 1 HOST 2 HOST 3 HOST 4, ETC.
VMs
Hypervisor:
Turns 1 server into many “virtual machines” (instances or VMs)
(VMWare ESX, Citrix XEN Server, KVM, Etc.)
2. Cloud Data Center 3. Cloud Federation1. Virtualization
Automation & Efficiency
Better resource utilization for each serverHardware abstraction for each server
Compute Pool Network Pool Storage Pool
Virtualized Servers Virtualized Networks Virtualized Storage
Next: Storage, Network…the building blocks
Resource pools for apps starting to form...Flexibility, Efficiency are key drivers

9. But questions arise as the environment grows...
“VM sprawl” can make things unmanageable very quickly
Where should you provision new VMs? How do you keep track of it all?
+
How do you empower employees to self-
service?
USERS ADMINS
How do you make your apps cloud aware?

14. In Summary, the Cloud Operating
System enables enterprises to:
1. Control and automate pools of resources
2. Efficiently allocate resources
3. Empower admins & users via self-service portals
4. Empower developers to make apps cloud-aware via APIs
Top 3 Benefits of a Common Platform
1. Easy to migrate data and applications to public clouds
when conditions are right
- based on security policies, economics, and other key
business criteria
2. No longer locked in with major investment in one
provider
3. Disaster recovery Source: from SlideShare

15. II. OPENSTACK

16. What is OpenStack?
1. Originated at NASA, with Rackspace
2. Driven by an open community process
3. First Three core projects:
 OpenStack Compute
 OpenStack Image Service
 Open Object Storage
4. Multiple hypervisors: Xen, KVM, ESXi,
Hyper-V, …
