Advanced Tools for Operators at Amazon.comDespite significant efforts in the field of Autonomic Computing, system operators will still play a critical role in administering Internet services for many years to come. However, very little is know about how system operators work, what tools they use and how we can make them more efficient. In this paper we study the practices of operators in a large-scale Internet service Amazon.com and propose a new set of tools for operators. The first tool lets the operators explore the health of system components and dependencies between them; the other monitors the actions of operators and automatically suggests solutions to recurring problems.
Large-scale Internet services invest significant amount of time and money to achieve high availability of their service, typically in the form of labor-intensive monitoring and response teams. Despite the high human resource expenditures, software and hardware failures still occur, and the human-intensive approach to monitoring and troubleshooting scales poorly as the service’s complexity and workload grow [1]. We hypothesize that the right kind of visualization and automation can reduce the human effort required for monitoring and repairing failures, allow operators to more quickly recognize a problem as recurrent, and facilitate better knowledge transfer in quickly-growing or high-turnover teams.
One of the authors spent three months working alongside the Amazon.com team responsible for real-time monitoring of hardware and software and for providing monitoring tools for the rest of the company. We collected quantitative data via interviews and surveys and analyzed the data in the trouble ticket database that contains information aboutMySQL and JavaSetting up the tutorial database
In this section we will create a new database, a new user, and a very simple table. MySQL has a two level directory like hierarchy for keeping databases and tables. At the root there is MySQL; under root you can only create “databases.” Database is almost like a directory, you can create “tables” under a database. Follow the steps listed below.
1. Start the mysql server (follow the CSIF MySQL tutorial).
2. Check if mysql server is running.
$ mysqladmin -u root -p status
Uptime: 434 Threads: 1 Questions: 86 Slow queries: 0 ...
3. Start the mysql client. We will use the command line client to create a new database, a new user and a table in the new database.
(a) $ mysql -u root -p
Welcome to the MySQL monitor. Commands end with ; or g.
mysql>
(b) Create a new database named ecs160tutorial.
mysql> CREATE DATABASE ecs160tutorial;
Query OK, 1 row affected (0.06 sec)
(c) Create a user with all privileges on this database. The user name will be tutorial user and the password will be 123456. Although this is NOT good practice, it will suffice.
mysql> GRANT ALL ON ecs160tutorial.* TO tutorialuser@’%’
-> IDENTIFIED BY ’123456’;
mysql> GRANT ALL ON ecs160tutorial.* TO tutorialuser@’localhost’
-> IDENTIFIED BY ’123456’;

The Eclipse Platform is designed for building integrated development environments (IDEs), and arbitrary tools. This paper is a general technical introduction to the Eclipse Platform. Part I presents a technical overview of its architecture. Part II is a case study of how the Eclipse Platform was used to build a full-featured Java development environment. Introduction When people speak of Eclipse, they very often mean the Eclipse Software Development Kit (SDK) which is both the leading Java™ integrated development environment (IDE) and the single best tool available for building products based on the Eclipse Platform.
The Eclipse SDK, a critical piece of the Eclipse tapestry, is a combination of the efforts of several Eclipse projects, including Platform [http://eclipse.org/platform], Java Development Tools (JDT [http://eclipse.org/jdt]), and the Plug-in Development Environment

Because of this growth the complexity of managing, accessing, and collaborating on electronic data has also grown. Secure access over the Internet has become essential for sharing files with team members in the next office or around the world. WebDrive® offers users secure file access and collaboration.
WebDrive uses industry standard Secure Socket Layer (SSL) and SFTP to ensure secure transmission of your files. WebDrive® can provide S/Key password encryption so that passwords cannot be read during transmission. WebDrive supports WebDAV protocol, which allows you to lock files, change the files, and then release the locks to allow other users to review and update the information.
WebDrive allows you to connect to a GroupDrive® , FTP, WebDAV (DAV), SFTP, Amazon-S3®, or FrontPage® Server using a LAN or Internet connection and to map a Network Drive to the server. You can then treat the server as if it were a hard disk on your system. Drag and drop files or copy files to and from the server using Windows Explorer; or use familiar DOS commands such as copy and xcopy. WebDrive FTP or HTTP enables any application instantly by integrating the server site into the Windows file system.

Web 2.0 is the term pioneered by O’Reilly for new generation Web applications.Live.com, start.com, Google maps, Google Docs, YouTube, Flickr, and MySpace are few examples. Adaptation of this technology vector has changed the web application development approach and methodology significantly.AJAX (Asynchronous JavaScript), RIA(Rich Internet Applications) and Web Services form the core components of Web 2.0applications.
AJAX delivers a rich user interface by displaying more dynamic content. Another common technique is Real Simple Syndications feeds (RSS), an XML based standard that allows subscribers to promote information feeds. This is most commonly used to subscribe to blogs and news articles. AJAX and Rich Internet Application (RIA) clients are enhancing client-end interfaces in the browser itself. XML is making a significant impact at both presentation and transport (HTTP/HTTPS) layers. To some extent XML is replacing HTML at the presentation layer while SOAP is becoming the XML-based transport mechanism of choice.
With Web 2.0, the functionality and experience of the sites become the primary focus, and the technology empowering the dynamic content is hidden behind the scenes to the average user. Yet the web applications underneath the polished finish remain just as complex, and add a variety of new and often unproven or unsecured technologies to the back end.
