4 OpenStack Short Introduction 4

5 Cloud Computing: State of the Enterprise What s Driving Enterprises to Cloud Systems? Cloud Benefits IT Consumers Agility through self-service automation On-demand provides OpEx vs. CapEx options Cloud Benefits IT Providers Better capacity planning and asset utilization Centralized monitoring and reporting Manage IT as a collection of provided services Not surprising: Many Enterprises have, or are looking to either deploy new clouds, or shift to cloud based management for existing infrastructure 5

6 OpenStack Overview What is OpenStack? Open source cloud software Generic solution for IaaS, PaaS and SaaS Modular architecture Web portal for cloud admins and self-service users Cloud services exposed through APIs CLI, Python libraries,... Combines compute, network and storage resources Self-service dashboard Services exposed through REST APIs Single Management Pane VM VM VM Virtualized Data Center Resources 6

9 Drivers for OpenStack Cloud Infrastructure What s exciting customers about OpenStack? Broad Industry Adoption and Participation in the Community Over 400 companies involved! Rich technology Ecosystem Provides choice / freedom to leverage underlying, Storage, Networking Infrastructure Standardized Cloud API layer Abstracts higher level Cloud Software & Services from Undercloud infrastructure specifics 9

10 OpenStack Use Cases Heterogeneous IaaS Consolidate Oracle Solaris and SPARC in existing OpenStack cloud Oracle Solaris Zones Based SPARC and x86 Centralized management 10

11 What OpenStack is not Out-of-the-Box Ready to Use Lots of work to configure underlying infrastructure Overall Integration Lots of moving parts Dependent on expertise, experience, vendors, maturing technology Mature Aggressive release cycle; short support lifespan Update capability is limited, often rip and replace However, it is improving Free OpenSource does not mean free Large investment to set up and support environment 11
