1. Deploying Moodle with Red Hat Enterprise Virtualization Brian McSpadden Director of Network Operations Remote-Learner.net

2. Traditional Web Hosting – it works, but... Consists of single servers: Some shared, some dedicated Limited flexibility Data “stuck” on a single server – limits scalability, upgradability and disaster recovery More difficult to manage and maintain consistency Difficult to fully utilize hardware

3. What is Cloud Hosting? It depends on who you ask Most would define it as computing on the “grid” Pooled resources – but not necessarily shared Underlying infrastructure is abstracted from the application layer Typically more green

4. RL is not simply cloud hosting Generic cloud hosting doesn't fit Host in an optimized environment

5. Hosting in an optimized cloud Entire stack designed for eLearning Unique hardware for unique needs Flexibility while maintaining consistency Grows with you Keeps up with the pace of eLearning innovation

6. What makes an optimized cloud different System resources are based upon eLearning's needs CPU Disk I/O Memory Application Stack (LAMP, Java) Provider keeps up with Moodle's changing needs Designed to handle peak loads – such as finals week

7. Remote Learner Cloud design principles Separate the user data from the OS image Design to handle failures Runs at 60% of capacity – handles minimum of two server failures – not oversold Designed to scale Consistent and well managed

8. Visualized

9. Major advantages over traditional hosting Built to scale – handles peak usage times Server hardware maintenance is a thing from the past Data stored on HA storage apart from server Disaster recovery simplified – easier to rebuild than fix Hardware can be fully utilized High levels of reliability for hosting big and small

10. Advantages of the RHEV Platform KVM Virtualization – Linux kernel as hypervisor Virtualization gets everything the kernel gets KSM (Kernel SamePage Merging) Live Migration Drivers/Modules (Hardware and Virtio) Extremely low overhead – outperforms bare metal in some cases with lower cost over VMWare Simplified/Unified Management Tools

11. Best in class applications: Meet best in class infrastructure
