Introduction to “Cloud Computing” Presented by Larry Studdiford April 4, 2011 1 EMGT 520 Information Systems Engineering

Slide 2:

What is the cloud vs. cloud computing? Services Capabilities Benefits Security Top 10 Cloud Computing Providers Summary Resources 2 EMGT 520 Information Systems Engineering Topics for Discussion

Slide 3:

…Just another metaphor for the Internet 3 EMGT 520 Information Systems Engineering What is the Cloud?

Slide 4:

Virtual servers available on the Internet More than 15 years in the making An offering of abstracted internet services “Just In Time” provisioning and scaling of services on shared hardware Three types of clouds: Private Cloud: on-premises, dedicated to an organization Hosted Private Cloud: Third party hosted; inaccessible to other customers Public Cloud: Externally hosted; available to multiple organizations; typically billed on a utility basis 4 EMGT 520 Information Systems Engineering What is Cloud computing?

Slide 5:

Software as a Services (SaaS) Multitenant architecture; single application delivered to thousands of customers From human resources to ERP to Google applications; single license for maintenance Utility Computing Storage via on-demand virtual servers Potentially replacing mission-critical datacenters one day Team Collaboration (ProjectWise, etc.) Web Services Discrete to full range of business services (Payroll processing, USPS, credit card processing, etc.) E-mail; Video Conferencing Platform as a service Delivers development environment as a service Build-your-own applications running on the provider’s infrastructure 5 EMGT 520 Information Systems Engineering Services

Slide 6:

Managed Service Providers (MSP) One of the oldest forms of cloud computing Applications exposed to IT in lieu of end-users Virus scanning, application monitoring, etc. Service Commerce Programs SaaS/MSP hybrid; most common in trading venues Expense management systems, travel or secretarial services, etc. Coordinates service delivery & pricing within user-established guidelines Internet Integration Integration of cloud-based services Typically concerned with SaaS providers 6 EMGT 520 Information Systems Engineering Services (continued)

Slide 7:

7 EMGT 520 Information Systems Engineering Capabilities A means for increasing capacity or add capabilities on the fly without investing in new infrastructure Accessible anywhere, from anywhere, anytime Personal Computer, Web Browser, Smartphone, etc. 24/7; 365 days/year Multi-office execution – connecting Teams remotely Multiple suppliers Competition to provide 99.9% uptime Delivery of services, from full-blown applications to storage servers to spam filtering

Slide 8:

Reduce Costs Pay-as-you-go Software updates; license fees No need for increased data capacity as business grows Improve Agility Rapid scalability – up or down Deploy services as-needed Exploit global business opportunities more rapidly Better user experience – collaboration tools Increased IT Reliability Back-up systems for failover protection -- simplified Server virtualization Reduced server sprawl 8 EMGT 520 Information Systems Engineering Benefits

9 EMGT 520 Information Systems Engineering Security

Slide 10:

Biggest concern in cloud computing Hackers: key logging, etc. Privacy: logging in from anywhere Concerns: Privileged User Access: Who do the service providers use, and what is their level of hiring scrutiny? Regulatory compliance: SSI, FOUO, etc. concerns with data transfer. Certifications, audits, etc.? Data Location: Jurisdiction issues; U.S.-friendly countries Data Segregation: firewalls between customers? Recovery: Complete restoration procedures, how long, etc. Investigative Support: has the provider gone through this before? Long-Term Viability: Return of data in the event of provider solvency, buy-out, etc. 10 EMGT 520 Information Systems Engineering Security

Slide 11:

Mitigation: Authentication techniques; authorization privileges for specific data Most up-to-date virus detection applied enterprise-wide; no need for individual computer installation Cloud providers’ reputation on the line; one slip up = loss of clientele Most providers work hand-in-hand with law enforcement Continual risk-based assessments ISO certifications; regulatory audits, Trade Association Memberships (Cloud Security Alliance, CSA) Security incident management Data encryption 11 EMGT 520 Information Systems Engineering Security

Slide 12:

12 EMGT 520 Information Systems Engineering Top 10 Cloud Computing Providers (in no particular order)

Slide 13:

Low Overhead: Reduce IT capital expenditures and operational overhead by up to 50% Subscription-based pricing: provide greater business flexibility through an on-demand, pay-as-you-go model that scales with your business Faster Deployment: Increase IT responsiveness and efficiency Ease of Access anytime/anywhere High Availability => Frees up IT resources for innovation 13 EMGT 520 Information Systems Engineering Summary
