- CloudStack is an open source cloud computing platform that was donated to the Apache Software Foundation in 2012. It provides infrastructure as a service and supports various hypervisors and physical hardware. - CloudStack has a scalable architecture designed to support thousands of hosts and VMs across multiple availability zones. It provides rich networking and storage capabilities. - CloudStack can support both traditional server virtualization workloads as well as "Amazon-style" workloads with software defined networks and object storage. - The CloudStack community is growing rapidly and encourages participation through mailing lists, IRC, forums and meetup groups.

• Apache CloudStack Community

3. Introducing
Apache CloudStack

4. CloudStack Background
• A proven IaaS Cloud Platform
– Developed since 2008 by Cloud.com
– Cloud.com development center in Hyderabad since 2009
– Cloud.com acquired by Citrix in 2011
– Donated to the Apache Software Foundation (ASF) in April
2012, where it is now an Incubator project
– First ASF community release in October 2012
– Powering some of the world’s largest clouds today

5. Enterprises are embracing Cloud
Service Providers Web 2.0 Enterprise

6. I’ve already virtualized my data center,
why do I need a cloud?

7. How is cloud really different from
server virtualization?

8. Virtualization does not make a cloud
Server Virtualization++ Cloud
Built for traditional enterprise Designed around big data,
apps & client-server compute massive scale & next-gen apps
•Enterprise arch for 100s of hosts • Cloud arch for 1000s of hosts
•Scale-up (pool-based resourcing) • Scale-out (horizontal resourcing)
•IT management-centric • Autonomic management
•1 administrator for Dozens of servers • 1 administrator for 1,000’s of servers
•Apps assume reliability • Apps assume failure
•Proprietary vendor stack • Open, value-added stack

9. Essentials of Cloud
• On-Demand and Self Serve
• Resource pooling, Multi-tenancy
• Massive Scale
• Rapid Elasticity
• APIs and Extreme Automation
• Total Homogeneous

24. Hadoop and CloudStack

25. Common interest
•Apache Foundation project
•Written in Java
•Runs on Linux, Mac OS/X, Windows, and Solaris
•Cloud-scale workloads
•Optimized for commodity hardware
•Hadoop Core includes:
ᵒ HDFS - Distributed file system derived from Google File System
ᵒ Map/Reduce – Distributed compute engine

26. Opportunities
•HDFS as Object Store solution for CloudStack cloud
•Hadoop on CloudStack
• Implement services similar to Amazon’s Elastic MapReduce
(EMR)
• Big Data workload readily moved to IaaS clouds
•CloudStack’s baremetal provisioning capabilities to build high
performance Hadoop clusters
•Feedback?
