- 2. Today’s Objective • To Explain how to get the “Cable” into the “Cloud” © Simplified Innovations Inc
- 3. What is Cloud Computing • Many definitions! • Model of enabling convenient, on-demand network access to shared computing resources (e.g., networks, servers, storage, applications, and services) that can be released with minimal service provider interaction. • It is simply a classification, an add-on to: • LAN, WAN, Grid, Etc… • The “Cloud” is a metaphor for the Internet • Data and applications now live in the internet © Simplified Innovations Inc

- 5. Characteristics of Cloud Computing • User Perspective • Accessible from anywhere you have internet • Minimal to no software to install • Typically OS agnostic • Work On Demand • No Backups to worry about • Scalable - Just add users and modules © Simplified Innovations Inc
- 6. Characteristics of Cloud Computing • Technical Perspective • High Availability • Typically web based • Pooled Resources • 5 nines • Data Redundancy • Scalable - Just add server resources © Simplified Innovations Inc
- 7. Cloud Options? • SaaS: • Software as a Service • IaaS: • Infrastructure as a Service • PaaS: • Platform as a Service • Colocation: • Private Cloud • Managed Hosting • Public Cloud • Hosted Applications: • Outsourced Cloud © Simplified Innovations Inc
- 8. Software as a Service (SaaS) • Delivers software through the internet, typically through a web browser, avoiding the challenge of installing and maintaining software at the customers site. © Simplified Innovations Inc
- 9. Characteristics of SaaS ADVANTAGES DISADVANTAGES Pay for only what you use Another login to remember Easily Scalable Can’t use offline (some exceptions) Automatic updates Data isn’t portable Web/Browser based Customer owns nothing No software to purchase Subscription based Customer owns nothing © Simplified Innovations Inc
- 10. © Simplified Innovations Inc
- 11. Infrastructure as a Service (IaaS) • Provides a technical computer infrastructure typically in the form of virtualized servers. Servers are rented by the customer and managed by the customer © Simplified Innovations Inc
- 12. Characteristics of IaaS ADVANTAGES DISADVANTAGES Complete Computing Environment Customer manages server operations Underlying Infrastructure fully managed Customer requires technical expertise Virtualized Infrastructure Customer owns software Scalable Pay per use Customer owns data Customer doesn’t own servers © Simplified Innovations Inc
- 13. © Simplified Innovations Inc
- 14. Platform as a Service (PaaS) • Provides a computing platform to facilitate deployment of typically SaaS application by limiting the challenges and cost of managing the underlying hardware and software foundation. © Simplified Innovations Inc
- 15. Characteristics of PaaS • A service used for software programmers to develop web applications • Software Platform is provided and managed • Programmers plugin their code and focus on their application rather than the challenges associated with managing the software components: • Servers • Databases • Bandwidth • Etc © Simplified Innovations Inc
- 16. © Simplified Innovations Inc
- 17. Colocation • A service where server racks, equipped with power, cooling, and bandwidth are rented on a monthly basis. Colocation eliminates the need to build and maintain a server room and all of its complexities. © Simplified Innovations Inc
- 18. Colo Features ADVANTAGES DISADVANTAGES Highly Secure – Physically Requires the technology experts in-house or consultants High Availability Infrastructure: • Internet, Power, Cooling Requires some sort of remote access technology On-site monitoring Customer owns software Computer hardware sensitive fire prevention Customer owns hardware © Simplified Innovations Inc
- 19. Colocation • Rent rack space in a datacenter • DataCenter Classifications • Tiers • Tier 1 – Server Closet • Tier 2 – Office Data Center • Tier 3 – Enterprise Datacenter • Tier 4 – Armed Guards © Simplified Innovations Inc
- 20. A Datacenter Tour © Simplified Innovations Inc
- 21. © Simplified Innovations Inc
- 22. Managed Hosting • The benefits of IaaS combined with the technical expertise of a managed services provider, effectively IaaS with an IT Department. © Simplified Innovations Inc
- 23. Managed Hosting ADVANTAGES DISADVANTAGES Complete Computing Environment Customer owns some software Underlying Infrastructure Fully Managed Server Operations Fully Managed Fully Virtualized Scalable Subscription Based Can be OS agnostic 99% of non-SaaS applications can be supported Licensing benefits with the right providers Customer owns data Customer doesn't own servers © Simplified Innovations Inc

- 25. Hosted Applications • Applications that are not natively designed as SaaS applications however in their nature can easily be supported by and outside service provider. © Simplified Innovations Inc
- 26. Hosted Applications • Non-SaaS Applications • Popular Examples: • Phone Systems • Microsoft Exchange • SharePoint • QuickBooks • Web Security • Creative Solutions Virtual Office © Simplified Innovations Inc
- 27. © Simplified Innovations Inc
- 28. Who is using it? • Home Users • Businesses • Non Profits • Government • Everyone © Simplified Innovations Inc

- #3: We are going to get the cable into the cloudsWith nearly 18M hits how can anyone begin to understand what CC is?High Level overviewAnswer QuestionsDiscuss concepts
- #4: WikidefinitionNational Institute of Standards and Technology
- #5: Standard Network DiagramInternal NetworkDMZ – Demilitarized ZoneThe InternetMove Apps and Data to the cloud
- #6: User perspectiveDiscuss the ubiquity of the internet (or lac there of) NC tripActive X installs
- #7: Technical perspectiveHA – brief explanation, datacenters, virtualizationPooled, explain virtualization, simply add RAM, HD, Servers
- #8: Ask questions and try to get definitions
- #10: Pay for, discuss modules, users, add-ons, integrationsDiscuss some software the ability to export
- #11: Some examples of Saas solutions.One talking point is that most Saas solutions will not integrate most other apps, therefore you will have to manage different logins for each Saas product being used.
- #15: Note that Paas solutions are typically used by many Saas providers. Typically not a consumer service.
- #16: Explain subscription based can be based on users, logins, etc.
- #17: Others include external IT and MindShift
- #18: Colo can be used by private companies and is typically used by most service providers as well unless they are using Iaas or have their own datacenter
- #24: Explain subscription based can be based on users, logins, etc.
