Amazon Web Services (AWS) is a cloud services platform that is totally secure, offers compute power, database storage, content delivery and other functionality to help businesses scale and grow.

AWS’ version of virtual computers has most of the attributes of a real computer including hardware (CPU(s) & GPU(s) for processing, local/RAM memory, hard-disk/SSD storage); a choice of operating systems; networking; and pre-loaded application software such as web servers, databases, CRM… nearly anything.

Each Amazon Web Services (AWS) system also virtualizes its console I/O (keyboard, display, and mouse), allowing Amazon Web Services (AWS) subscribers to connect to their AWS system using a modern browser.

Amazon Web Services (AWS) includes more than 70 services and is continually launching new features and functionality.

Amazon Web Services (AWS) operates 35 availability zones within 13 geographic Regions around the world, with 12 more availability zones and 5 more regions coming online soon.

What AWS offers?

• Low ongoing cost: Pay-as-you-go pricing with no up-front expenses or long-term commitments.
• Instant elasticity and flexible capacity scaling up and down: Eliminate guessing on your infrastructure capacity needs.
• Speed and agility:  Develop and deploy applications faster Instead of waiting weeks or months for hardware to arrive and to be installed.
• Apps, not ops: Focus on projects lets you shift resources away from data centre investments and operations and move them to innovative new projects and applications.
• Global reach: Take your apps global in minutes.
• Open and flexible: You choose the development platform or programming model that makes the most sense for your business.
• Secure: Allows your application to take advantage of the multiple layers of operational and physical security in the AWS data centres to ensure the integrity and safety of your data.

Elastic Compute Cloud (EC2)

• A web service that provides resizable computing capacity in the cloud, allowing you to use web service interfaces to launch instances with a variety of operating systems.
• EC2 allows creating virtual Machines (VM) on demand. Pre-configured template Amazon Machine Image (AMI) can be used to get up and run immediately.
• Amazon Elastic Compute Cloud (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.
• Elastic load balancing automatically distributes incoming application traffic across multiple Amazon EC2 instances.
• With auto-scaling, you can ensure that the number of Amazon EC2 instances you’re using scales up seamlessly during demand spikes to maintain performance and scales down automatically during demand lulls to minimize costs.
• Cluster Compute, Cluster GPU, and High Memory Cluster instances have been specifically engineered to provide high-performance network capability and can be programmatically launched into clusters – allowing applications to get the low-latency network performance required for tightly coupled node-to-node communication.
• It enables you to get significantly higher performance, lower network jitter and lower latencies.
• Pay only for resources actually consumes hours.

Simple storage services (S3)

• 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.
• Amazon S3 is simple to use with a web-based management console and mobile app. S3 provides full REST APIs and SDKs for easy integration with third-party technologies.
• Write, read and delete objects containing from 1 byte to 5 terabytes of each data. 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 stored in one of the several A bucket has a flat directory structure.
  • A bucket is a container for objects and describes the location, logging, accounting, and access control.
  • You can choose a region to optimize for latency, minimize costs or address regulatory requirements.
  • Objects stored in a region never leave the region unless you transfer them out.
  • 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.
• S3 charges based on per GB-month and per I/O requests and per Data modification requests.
• Pricing: Pay as you Go, Payless by Using More.
  • Up to 50 TB storage : US $ 0.023 GB/Month
  • 51TB to 100 TB : US $ 0.022 GB/Month
  • 500 TB + : US $ 0.021 GB/Month

Mozilla Extension for Amazon S3
