Amazon Web Services
With AWS you can requisition compute power, storage, and other services–gaining access to a suite of elastic IT infrastructure services as your business demands them. With AWS you have the flexibility to choose whichever development platform or programming model makes the most sense for the problems you’re trying to solve. You pay only for what you use, with no up-front expenses or long-term commitments, making AWS the most cost-effective way to deliver your application to your customers and clients.
Using Amazon Web Services, an e-commerce web site can weather unforeseen demand with ease; a pharmaceutical company can “rent” computing power to execute large-scale simulations; a media company can serve unlimited videos, music, and more; and an enterprise can deploy bandwidth-consuming services and training to its mobile workforce.
Amazon Web Services delivers a number of benefits for IT organizations and developers alike, including:
• Cost-effective. Pay only for what you use, as you use it, with no up-front commitments. As the Amazon Web Services cloud grows, our operations, management and hardware costs shrink, and we pass the savings onto you.
• Dependable. Utilize a battle-tested, web-scale infrastructure that handles whatever you throw at it. The Amazon Web Services cloud is distributed, secure and resilient, giving you reliability and massive scale.
• Flexible. Build any application you want using any platform or any programming model. You control the resources you consume and fit them into your application as you see fit.
• Comprehensive. Don’t start from scratch. Amazon Web Services gives you a number of services you can incorporate into your applications. From databases to payments, these services help you build great applications cost effectively and with less up-front investment.
The AWS cloud computing platform provides the flexibility to build your application, your way, regardless of your use case or industry. You can save time, money, and the difficulties of managing your own infrastructure, without compromising on scalability, security, or dependability.
A handful of the types of solutions customers have built include:
Application Hosting, Backup and Storage, Content Delivery, E-Commerce,High Performance Computing, Media Hosting, On-Demand Workforce, Search Engines,Web Hosting
1). Amazon Elastic Compute Cloud (Amazon EC2)
It is a web service that provides resizable compute capacity in the cloud. It is designed to make web-scale computing easier for developers.
Amazon EC2’s simple web service interface allows you to obtain and configure capacity with minimal friction. It provides you with complete control of your computing resources and lets you run on Amazon’s proven computing environment. Amazon EC2 reduces the time required to obtain and boot new server instances to minutes, allowing you to quickly scale capacity, both up and down, as your computing requirements change. Amazon EC2 changes the economics of computing by allowing you to pay only for capacity that you actually use. Amazon EC2 provides developers the tools to build failure resilient applications and isolate themselves from common failure scenarios.
Functionality:
Amazon EC2 presents a true virtual computing environment, allowing you to use web service interfaces to launch instances with a variety of operating systems, load them with your custom application environment, manage your network’s access permissions, and run your image using as many or few systems as you desire.
To use Amazon EC2, you simply:
• Create an Amazon Machine Image (AMI) containing your applications, libraries, data and associated configuration settings. Or use pre-configured, templated images to get up and running immediately.
• Upload the AMI into Amazon S3. Amazon EC2 provides tools that make storing the AMI simple. Amazon S3 provides a safe, reliable and fast repository to store your images.
• Use Amazon EC2 web service to configure security and network access.
• Choose which instance type(s) and operating system you want, then start, terminate, and monitor as many instances of your AMI as needed, using the web service APIs or the variety of management tools provided.
• Determine whether you want to run in multiple locations, utilize static IP endpoints, or attach persistent block storage to your instances.
• Pay only for the resources that you actually consume, like instance-hours or data transfer
2). Amazon SimpleDB
It is a web service providing the core database functions of data indexing and querying. This service works in close conjunction with Amazon Simple Storage Service (Amazon S3) and Amazon Elastic Compute Cloud (Amazon EC2), collectively providing the ability to store, process and query data sets in the cloud, making web-scale computing easier and more cost-effective for developers.
A traditional, clustered relational database requires a sizable upfront capital outlay, is complex to design, and often requires a DBA to maintain and administer. Amazon SimpleDB is dramatically simpler, requiring no schema, automatically indexing your data and providing a simple API for storage and access. This approach eliminates the administrative burden of data modeling, index maintenance, and performance tuning. Developers gain access to this functionality within Amazon’s proven computing environment, are able to scale instantly, and pay only for what they use.
Functionality:
Amazon SimpleDB provides a simple web services interface to create and store multiple data sets, query your data easily, and return the results. Your data is automatically indexed, making it easy to quickly find the information that you need. There is no need to pre-define a schema or change a schema if new data is added later. And scale-out is as simple as creating new domains, rather than building out new servers.
To use Amazon SimpleDB you:
• Build your data set:
Use CreateDomain, DeleteDomain, ListDomains, DomainMetadata to create and manage query domains
Use Put, Batch Put, & Delete to create and manage the data set within each query domain
• Retrieve your data :
Use GetAttributes to retrieve a specific item
Use Select to query your data set for items that meet specified criteria
• Pay only for the resources that you consume
3). Amazon S3
It is storage for the Internet. It is designed to make web-scale computing easier for developers.
Amazon S3 provides a simple web services interface that can be used to store and retrieve any amount of data, at any time, from anywhere on the web. It gives any developer access to the same highly scalable, reliable, fast, inexpensive data storage infrastructure that Amazon uses to run its own global network of web sites. The service aims to maximize benefits of scale and to pass those benefits on to developers.
Functionality:
Amazon S3 is intentionally built with a minimal feature set.
• Write, read, and delete objects containing from 1 byte to 5 gigabytes of data each. The number of objects you can store is unlimited.
• Each object is stored in a bucket and retrieved via a unique, developer-assigned key.
• A bucket can be located in the United States or in Europe. All objects within the bucket will be stored in the bucket’s location, but the objects can be accessed from anywhere.
• Authentication mechanisms are provided to ensure that data is kept secure from unauthorized access. Objects can be made private or public, and rights can be granted to specific users.
• Uses standards-based REST and SOAP interfaces designed to work with any Internet-development toolkit.
• Built to be flexible so that protocol or functional layers can easily be added. Default download protocol is HTTP. A BitTorrent™ protocol interface is provided to lower costs for high-scale distribution. Additional interfaces will be added in the future.
• Reliability backed with the Amazon S3 Service Level Agreement.
4). Amazon CloudFront
It is a web service for content delivery. It integrates with other Amazon Web Services to give developers and businesses an easy way to distribute content to end users with low latency, high data transfer speeds, and no commitments.
Amazon CloudFront delivers your content using a global network of edge locations. Requests for your objects are automatically routed to the nearest edge location, so content is delivered with the best possible performance. Amazon CloudFront works seamlessly with Amazon Simple Storage Service (Amazon S3) which durably stores the original, definitive versions of your files. Like other Amazon Web Services, there are no contracts or monthly commitments for using Amazon CloudFront – you pay only for as much or as little content as you actually deliver through the service.
Functionality:
Amazon CloudFront has a simple, web services interface that lets you get started in minutes. In Amazon CloudFront, your objects are organized into distributions. A distribution specifies the location of the original version of your objects. A distribution has a unique CloudFront.net domain name (e.g. abc123.cloudfront.net) that you can use to reference your objects through the network of edge locations. If you wish, you can also map your own domain name (e.g. images.example.com) to your distribution.
To use Amazon CloudFront, you:
• Store the original versions of your files in an Amazon S3 bucket.
• Create a distribution to register that bucket with Amazon CloudFront through a simple API call.
• Use your distribution’s domain name in your web pages or application. When end users request an object using this domain name, they are automatically routed to the nearest edge location for high performance delivery of your content.
• Pay only for the data transfer and requests that you actually use.
5). Amazon Simple Queue Service
It offers a reliable, highly scalable, hosted queue for storing messages as they travel between computers. By using Amazon SQS, developers can simply move data between distributed components of their applications that perform different tasks, without losing messages or requiring each component to be always available. Amazon SQS makes it easy to build an automated workflow, working in close conjunction with the Amazon Elastic Compute Cloud (Amazon EC2) and the other AWS infrastructure web services.
Amazon SQS works by exposing Amazon’s web-scale messaging infrastructure as a web service. Any computer on the Internet can add or read messages without any installed software or special firewall configurations. Components of applications using Amazon SQS can run independently, and do not need to be on the same network, developed.
Functionality:
• Developers can create an unlimited number of Amazon SQS queues with an unlimited number of messages.
• A queue can be created in the United States or in Europe. Queue names and message stores are independent of other regions.
• The message body can contain up to 8 KB of text in any format.
• Messages can be retained in queues for up to 4 days.
• Messages can be sent and read simultaneously.
• When a message is received, it becomes “locked” while being processed. This keeps other computers from processing the message simultaneously. If the message processing fails, the lock will expire and the message will be available again. In the case where the application needs more time for processing, the “lock” timeout can be changed dynamically via the ChangeMessageVisibility operation.
• Developers can access Amazon SQS through standards-based SOAP and Query interfaces.
• Developers can securely share Amazon SQS queues with others. Queues can be shared with other AWS accounts and Anonymously. Queue sharing can also be restricted by IP address and time-of-day.
6). Amazon Elastic MapReduce
It is a web service that enables businesses, researchers, data analysts, and developers to easily and cost-effectively process vast amounts of data. It utilizes a hosted Hadoop framework running on the web-scale infrastructure of Amazon Elastic Compute Cloud (Amazon EC2) and Amazon Simple Storage Service (Amazon S3).
Using Amazon Elastic MapReduce, you can instantly provision as much or as little capacity as you like to perform data-intensive tasks for applications such as web indexing, data mining, log file analysis, machine learning, financial analysis, scientific simulation, and bioinformatics research. Amazon Elastic MapReduce lets you focus on crunching or analyzing your data without having to worry about time-consuming set-up, management or tuning of Hadoop clusters or the compute capacity upon which they sit.
Functionality:
Amazon Elastic MapReduce automatically spins up a Hadoop implementation of the MapReduce framework on Amazon EC2 instances, sub-dividing the data in a job flow into smaller chunks so that they can be processed (the “map” function) in parallel, and eventually recombining the processed data into the final solution (the “reduce” function). Amazon S3 serves as the source for the data being analyzed, and as the output destination for the end results.
To use Amazon Elastic MapReduce, you simply:
• Develop your data processing application authored in your choice of Java, Ruby, Perl, Python, PHP, R, or C++. There are several code samples available in the Getting Started Guide that will help you get up and running quickly.
• Upload your data and your processing application into Amazon S3. Amazon S3 provides reliable, scalable, easy-to-use storage for your input and output data.
• Log in to the AWS Management Console to start an Amazon Elastic MapReduce “job flow.” Simply choose the number and type of Amazon EC2 instances you want, specify the location of your data and/or application on Amazon S3, and then click the “Create Job Flow” button. Alternatively you can start a job flow by specifying the same information mentioned above via our Command Line Tools or APIs.
• Monitor the progress of your job flow(s) directly from the AWS Management Console, Command Line Tools or APIs. And, after the job flow is done, retrieve the output from Amazon S3.
• Pay only for the resources that you actually consume. Amazon Elastic MapReduce monitors your job flow, and unless you specify otherwise, shuts down your Amazon EC2 instances after the job completes.
