Class Notes

Introduction
Cloud Computing is a design and style philosophy that breaks the Operating Technique and Applications from the Hardware
Internet Applications
Are Designed in Web Programming Languages
Usually Use Databases to Retailer Information
Clusters
Are Usually Utilised for Database Servers (MySQL, Microsoft Active Directory)
Load is balanced among servers in a cluster. If a single server fails the cluster responds by not sending traffic to it.
Servers sustain the same information by making use of replication
Terminal Solutions
Primarily based off of old Mainframe and Dumb Terminal Architecture
Now You Use Terminal Solutions Servers and Thin Clients
Thin Customers can be Hardware Devices or Software installed on a personal computer
All processing occurs on Terminal Solutions Server and the Thin Client just gets a “Window” into the server.

Application Servers
Uses Terminal Services but rather of supplying a full Atmosphere it only delivers a specific Application.
Virtualization
Uses Desktop Clientele Software or Hypervisors to enable you to set up a number of Operating Systems on to a single physical server.
Hypervisors
i. Hypervisor is installed on the physical hardware to help the Operating Systems, and Management Software is employed to configure every Virtual Machine, or Instance.
ii. VMWare utilizes ESXi as the Hypervisor and vSphere for the Management Application
Hosted Situations
Examples: Amazon EC2 , Microsft Azure
You Spend for Use (Storage Quantity, CPU Power, RAM, Bandwidth)
Edge Areas are employed by some providers to let for more rapidly access to servers over the Web. You might be charged to send information from the principal servers to the Edge Servers
Hosted Options
Are pieces of software that are hosted by vendors using the Cloud (Hosted Exchange, Google Docs, Adobe Acrobat.com, Mozy)
Public vs. Private Clouds
The Public Cloud is Cloud Computing utilised from On-line Vendors
Private Clouds are environments on company/organization home that use Cloud Technologies.
Final Thoughts….
Safety… Most Tiny Organization Safety is poor. Security for most modest to medium sized business will be greater when systems are hosted in the cloud
Regional and World wide web Bandwidth becomes far more critical with Cloud Computing. Even on the LAN you may possibly finish employing all of your bandwidth.
