export them back at any time. . 8) AWS Marketplace is an online store that helps you find, buy and quickly deploy software that runs on AWS. . 9) Enhanced Networking enables you to get significantly higher packet per second (PPS) performance, lower network jitter and lower latencies. 6. Repeat the same exercise as above for the following Amazon services: a. SimpleDB; and b. Simple Storage Service (S3). a. SimpleDB Amazon SimpleDB is PaaS. PaaS provides platform on which new software can be developed and deployed. Amazon SimpleDB works as platform that provides core database function and the ability to process data sets in the cloud. Amazon SimpleDB is also IaaS(by ec2 instance) . 1) Highly available and flexible non-relational data store . 2) Automatically creates multiple geographically distributed copies of each data item you store. b. Simple Storage Service (S3) Amazon S3 is PaaS. PaaS provides platform on which new software can be developed and deployed. Amazon S3 utilizes a simple web services interface that can be use to store and retrieve any amount of data from anywhere on the web. It is a platform that developers can run their own applications. Amazon S3 is also IaaS (by ec2 instance) 1) Write read, delete on objects containing from 1 byte to 5 TB each 2) Each object is stored in a bucket and retrieved via a unique key
. 3) HTTp or BitTorrent download protocol . 4) Support for multiple access control mechanisms, as well as encryption for both secure transit and secure storage on disk . 5) Objects are redundantly stored on multiple devices across multiple facilities in an Amazon S3 region. . 6) Put and copy operations synchronously store your data across multiple facilities before returning success. . 7) Data integrity regularly verified using checksum . 8) Reduced Redundancy Storage(RSS) allows to reduce cost storing non-critical data at lower level of redundancy. 7. Consider the example of Zing Interactive Media and explain how you would launch the same service today using Amazon EC2. Specifically list the steps (and costs) you would avoid by doing so. 1) Rent space on a hosting site—the “cage” on an AT&T hosting facility 2) Anticipate the peak use amount and develop a redundancy schema 3) Specify the technical requirements for the servers to meet the capacity plans . 4) Negotiate vendor- and support contracts . 5) Lease T1 lines for the “cage” connectivity and pay for them regardless of the actual use . 6) Purchase and install the computing and networking gear (load balancers, switches, firewalls, and other networking appliances) . 7) Purchase and install the software platform (operating systems, databases, software libraries, compilers) . 8) Hire an IT team of networking experts, a systems administrator, and a database administrator . 9) Deploy and maintain the unique software that actually delivered the service By applying the Amazon EC2, the steps to lunch the Zing Interactive Media is: . 1) Buy a server . 2) Rent T1 lines, or go through the other hoops described above.
