- 5. Delivery Models ● Software as a service (SaaS) – Web-based applications (Google, Facebook) ● Platform as a service (PaaS) – Software environments (Google App Engine, Microsoft Windows Azure) ● Infrastructure as a service (IaaS) – Computing environments (Amazon Web Services, Rackspace Cloud) – This presentation will focus on IaaS 5
- 6. IaaS Deployment Models ● Public – Third party off-site service provider (Amazon Web Services, Rackspace Cloud) ● Private – Virtualization running in your data center (OpenStack, Xen Cloud Platform) ● Hybrid – Combination of public and private models 6
- 7. Managing Your Online Presence ● Use an IaaS deployment model to: – Create an online presence – Expand and scale to meet demand ● Amount of investment varies for each deployment model – Public – Private – Hybrid 7
- 8. Public IaaS ● Only pay for exactly what you use (computing resources, storage, bandwidth) – No upfront hardware cost – Costs scale with increased demand – Opportunity to outsource IT services 8
- 9. Public IaaS - Examples ● Amazon Web Services (AWS) – Elastic Compute Cloud (EC2) – Simple Storage Service (S3) ● Rackspace Cloud – Cloud Servers – Cloud Files 9

- 14. Private IaaS ● Many free and open source software options available – No software cost – Leverage existing hardware infrastructure – Adjust resources with changing demand – In-house IT services 14
- 15. Private IaaS - Examples ● OpenStack – OpenStack Compute – OpenStack Object Storage – OpenStack Imaging Service ● Xen Cloud Platform (XCP) – Xen Hypervisor – Open vSwitch – Xen Management API (XAPI) 15
- 16. OpenStack Architecture openstack.org 16
- 17. XCP Architecture xen.org 17
- 18. Hybrid IaaS ● Leverage existing private infrastructure while bursting and/or migrating into the public cloud – Carefully mix public and private cloud resources – Optimize public and private infrastructure costs – Selectively outsource IT services 18
- 19. Hybrid Cloud Architecture cloudave.com 19
- 20. Cloud Computing Challenges ● Privacy and security – Data stored on public servers – Malware protection outsourced ● Availability and performance – Online service outages and backups – Content delivery networks or content distribution networks (CDNs) ● Open standards – Image format compatibility 20
- 21. Cloud Computing Adoption spiceworks.com 21
- 22. IaaS Adoption gogrid.com 22
- 23. Future of Cloud Computing ● Web-based operating systems – Google Chrome OS ● Virtual desktop infrastructure (VDI) – Citrix XenDesktop, VMware View, Spice ● Client virtualization – Citrix XenClient, Virtual Computer’s NxTop, Qubes OS ● Desktop as a service (DaaS) – Combination of the above 23
