- InMobi moved to using Citrix CloudPlatform to power their private cloud, replacing their home-built systems which were brittle and difficult to scale. - Their architecture with CloudPlatform includes management servers, MySQL servers, primary storage using NexentaStor on JBODs, and secondary GlusterFS storage for redundancy. - This allows InMobi to easily provision development and test environments in a self-service manner while maintaining isolation, security, and scalability as their needs grow.

- 4. About InMobi
- 5. About InMobi
- 7. • Development and Test Environment • Scalable Web Applications and Content Services • High Speed Server Resource Deployment • And More.. Why Cloud ?
- 8. • Disconnected Tools, Servers, People • Slow Build and Release Cycles • Multiple Build and Test Systems Across Locations • Home-Built Systems are Brittle, Error-Prone, and Not Scalable • Difficult to Build, Test, and Recreate the Data • Difficult to Audit Processes and Predict Schedules • Time, Money Wasted on Broken Builds • Dedicated Build/Test Servers are not Fully Utilized Why Dev / Test in the Cloud ?
- 9. • Self-Service Developers can provision their own environments • Usage Measurement We worry about VM sprawl • Isolated Networks Must not let dev/test interfere with the real world • Commodity As cheap as practical • May also House Production Workloads How Does a Dev/Test Cloud Look Like ?
- 10. • Budget • Integration with Public Cloud • Scaling • Reconfiguration • Legacy Hardware Early Assessments & Results
- 11. • Leverage Existing Infrastructure • Customization and Control • Regulatory/Security Requirements • Cost Why Private Cloud ?
- 12. • Scalable Grow-as-you-need, expand across borders • Open Source Community Support Active user and development support base • Advanced Networking VLAN integrated, SDN ready • Multi-Tenancy • Multi-Hypervisor Support Why Citrix CloudPlatform ?
- 13. • Easy to Deploy • Speed to Production • Documentation Why Citrix CloudPlatform ?
- 15. • Bring Everyone in the Room • Know the Fine Print • Understand Workloads • Understand Bottlenecks The Design Phase
- 16. • CloudStack Management Server • MySQL Servers • Primary & Secondary Storage • Hypervisor Farm Redundancy and Resilience
- 17. Management Layout & Design
- 18. • Dell PE R610’s & R720’s • 96 – 256 GB RAM • 40-80 CPU Cores • 2 Advanced + 1 Basic Zones • 1 Pod in Each Zone • 1 – 5 Clusters in Each Pod • XenServer 6.2 Compute
- 19. • Gigabytes • Management Uses 1 Bonded NIC • Public + Guest Uses 1 Bonded NIC • Storage Uses 1 Bonded NIC (10G) • Access & Storage Networks are Isolated • Dell 6248 • Dell 8132 Network
- 20. • ZFS Filesystem, Based on OpenSolaris and Debian • Linux Open Source Code Bases ( Moving to illumos) • Software Only • Platform, Plugins and Adapters • Compelling Advantages over Proprietary Filesystems Primary Storage Design (NexentaStor)
- 21. What is NexentaStor ?
- 22. • Simple Installation and Management. • Optimized Base Configuration that Allows for: ‣ Easily reproducible configuration on a massive scale ‣ Generalized storage skill set required to maintain extensive infrastructure ‣ Little or no need for modification to achieve high performance Advantages of NexentaStor Storage Appliance
