7. Since 2008 CloudStack has powered hundreds of clouds
• Secure, multi-tenant cloud orchestration
platform
– Turnkey platform for delivering IaaS clouds
– Hypervisor agnostic
– Highly scalable, secure and open
– Complete Self-service portal
“CloudStack has successfully penetrated the – Open source, open standards
service provider market...and racked up some
solid wins in the enterprise to boot.” – Deploys on premise or as a hosted solution
James Staten
Vice President, Principal Analyst • Deliver cloud services 50 times faster at
1/5th the cost
• 130 commercial deployments

22. Architecture definition is a process
IaaS Cloud
Define target workloads
Determine how that workload will be delivered reliably
Determine the necessary functionality and performance
Develop your technical architecture
Implement your environment

26. How do you build clouds to
meet customer’s needs

- Amazon-Style availability zone
27. Designing a zone for a traditional workload

28. Designing a zone for a traditional workload
• Can achieve significant reliability for
vCenter/XenCenter
applications running in one zone.
Enterprise Networking (e.g., VLAN) • Reliability of individual nodes is very high.
• All zone storage is replicated to a second

Enterprise Storage (e.g., SAN) • In event of failure, images are recovered
from second storage array.
• Existing workloads will run reliably.
• Little cost benefit over existing approaches

34. Key takeaways
1. Understand your workload and the type of cloud you
want to build.
2. Consider the services you will be delivering from the
cloud in the future.
3. Choose a platform and architecture that is flexible
enough to support you today and in the future.
35. Learn how to build your own cloud
