Please give us a THUMBS UP if you like our videos!!! Info Level: Beginner Presenter: Eli the Computer Guy Date Created: December 17, 2010 Length of Class: 75 Minutes Tracks Cloud and Virtual Computing Prerequisites None Purpose of Class This class introduces students to the world of Cloud Computing and explains that Cloud Computing is more then Virtualization. Chapters Introduction (00:00) Web Applications (06:51) Clustering (09:26) Terminal Services (16:26) Application Servers (25:13) Virtualization (30:00) Hosted Instances (44:05) Hosted Solutions (54:41) Public vs. Private Clouds (58:06) Final Thoughts (60:00) Class Notes Introduction Cloud Computing is a design philosophy that breaks the Operating System and Applications from the Hardware Web Applications Are Created in Web Programming Languages Generally Use Databases to Store Data Clusters Are Generally Used for Database Servers (MySQL, Microsoft Active Directory) Load is balanced between servers in a cluster. If one server fails the cluster responds by not sending traffic to it. Servers maintain the same data by using replication Terminal Services Based off of old Mainframe and Dumb Terminal Architecture Now You Use Terminal Services Servers and Thin Clients Thin Clients can be Hardware Devices or Software installed on a computer All processing happens on Terminal Services Server and the Thin Client simply gets a “Window” into the server. Example: www.ncomputing.com Application Servers Uses Terminal Services but …

Sure, it’s all good as long as the cloud didn’t get hacked or screw up. This kind of computing environment remind me of the movie TERMINATOR, where Skynet is the cloud. When Skynet went crazy, the whole world got waisted. I am skeptical regarding this type of system. When you mention government, it reminded me of communism, where one government controls all. Cloud computing would be the communist of all computer technology.

Dear Eli, I like your presentation very much on cloud computing. My question is about clustering. Is it possible to form a cluster with servers that are in different location…like one server is in the US while the other is in Japan and the other in New Zealand? Or is there a limitation distance wise? I’m working on a project that connects Servers in different countries by mirroring databases… but it has a limitation of the amount of servers that can be connected. You did a great job.

I kinda of see cloud computer as a redundancy. since technology is on a exponential curve buying 3 servers is wasting money because if the power block fails for whatever reason, then the cost is most likely less especially on the fact that cloud computing opens many security risks. Not by volume of viruses but by the content of a brilliant hacker much more accessibility is achieved. Just my thoughts

@WumiO The best “small” scale thing you could look at would be online backup. You can use RSync and Deltacopy which are free pieces of software to upload client data to your own server. Being that Comcast internet is about $60 a month and a 3 TB hard drive is around $200. You could setup a linux box with a massive hard drive for around $400, and just pay for internet that you probably already have. You can probably charge up to $20 per month per system that is being backed up.
