Up-and-coming computing technology that uses the internet (the “cloud”) and central remote servers to maintain information and applications. Allows consumers and businesses to use applications without installation and access their personal files at any computer with internet access. More efficient computing by centralizing storage, memory, processing and bandwidth. Three segments: ◦ Applications ◦ Platforms ◦ Infrastructure
4 Layers Clients – the computer hardware or software that relies on the cloud service ◦ Mobile, Thin Client, Thick Client Application – the program the cloud computing company offers (replaces software) ◦ Many different applications Platform – packages, services, or infrastructure offered from the company that runs the application ◦ Services, Solutions, Storage Infrastructure – mode of delivery, typically through virtualization Servers – the computer hardware or software products created to deliver the cloud services ◦ Maintained by service company
Private Cloud ◦ Also called an internal cloud, is a cloud that operates on private networks ◦ Offer higher security and better reliability but cost more Hybrid Cloud ◦ Mix of private and public cloud offerings Public Cloud ◦ Mainly web applications and services ◦ More common than others Hybrid
Al Gore gave us the Internet Broadband got cheap Not everyone had to build in house data centers The computer running the application could be far from the person using it Only a fast connection was needed which led to SOFTWARE AS A SERVICE (SaaS)
Large enterprises had complex requirements Data outside firewall Cost vs. usage
With VIRTUALIZATION : Applications and infrastructure are independent and allowing servers to be shared by applications. Runs everywhere Doesn’t have to run in you data center or in your applications providers center. -Computing Service that charges based on the computing resources you use aka Pay As You Go Open source software must be utilized in order for cloud to “grow”
Lack of confidence by business leaders in cloud computing Possible solution ◦ Introduce them to internal clouds first, eventually incorporating a system that keeps some information in house and some information public.
Helps global corporations work effectively from locations around the world. Cost Savings. $50.00 per user of Google App Enterprise version vs. Microsoft Office Pro $499.99. Saves time, provides real time updates. ◦ Installing and configuring the OS, running multiple applications, and providing database connections
Using IBM Blue Cloud software and services to turn existing corporate data centers into its own private cloud protected by a firewall.
By law corporations must know where physical copies of their documents are at all times. Complying with Sarbanes -Oxley on corporate financial reporting. Complying with Health Insurance Portability & Accountability Act (HIPPA), which sets rules for security and privacy of medical records.
Google’s search engine and applications are some of the early products of efforts. Microsoft released online software called Windows Live for photo-sharing, file storage and other applications served from new data centers. Yahoo has taken the same steps. IBM has devoted 200 researchers to this project. Amazon.com just broadened access for software developers to its “Elastic Compute Cloud” ◦ Lets small software companies pay for processing power streamed from Amazon’s data centers.
Potential uses are widespread. According Business Week, “Google, Microsoft, and others are also building online services designed to give consumers greater access to information to help manage their health care.”
Technical standards for connecting various computer systems and pieces of software could slow the progress on new products. U.S. broadband penetrations lags in Europe and Asia. Without high-speed connections, especially wireless ones, services wont be widely accessible. Privacy protection.
Convenience and Simplicity Flexibility Hybrid that allowed any software to be easily ran as a service in a data center that someone owns and manages that led to VIRTUALIZATION.
Reduce IT Infrastructure costs Business benefits from the ability to efficiently ramp up & power down Introduce New IT services Financial Savings Streamline processes and Increased Innovation Assist with Cost savings in terms of Wasted Resources Utilize Service in a Single Day
1) Where is my data stored? ◦ Can be found in many different places 2) What do I do when I can't access my data? ◦ Reset computer router, Reload program 3) What can't I do? ◦ Limited power 4) Is it safe? ◦ Off sourced material
5) Do I need to keep copies of my data at home? ◦ YES! 6) Are my files too big? ◦ Size only matters in the actual storage 7) What happens if you go out of business? ◦ Occupied storage space would be liqudated 8) What happens if I forget to pay for a month?
