Amazon Web Services (AWS) is a subsidiary of Amazon that offers a large suite of infrastructure and application services that enable you to run nearly everything in the cloud – from enterprise applications to large data projects and mobile apps.
Amazon Web Services or AWS is a popular cloud computing platform. It is a large system of pay-as-you-go data centers that provide infrastructure for a huge portion of the World Wide Web. Amazon Web Services is become one of the key job providing areas in the IT industry.

Amazon’s internal IT resource management built AWS, which expanded and grew into an innovative and cost-effective cloud solution provider.

The Amazon Web Services (AWS) first service, Amazon S3 was launched in March 14, 2006 .  According to Amazon, the new service as “storage for the Internet.” The first objects were anywhere from 1 byte to 5 gigabytes, AWS said and as at the time AWS charged $0.15 per gigabyte of storage per month and $0.20 per gigabyte of data transferred. The company packages AWS with scalable and virtually unlimited computing, storage and bandwidth resources.

AWS is now the industry’s market leader, with customers spread over almost every country throughout the world, and a huge share of the Infrastructure as a Service (IaaS) market. 

The AWS Cloud manages 60 Availability Zones in 20 geographic regions around the world. Plans have been announced for 12 availability zones and 4 additional regions in Bahrain, Cape Town, Hong Kong (Special Administrative Region of China) and Milan.

This cloud computing platform range, though still growing, offers more than thirty services mainly IaaS and PaaS, although SaaS services have also been launched (messaging, EFSS ).

There are many AWS consulting partners who are major service providers.

In order to meet everyone’s needs, Amazon offers a range of instance types with different configurations in terms of CPU, memory, and storage and network resources. In addition, each type is available in several sizes to meet different workloads.

Instance types are grouped into families according to target application profiles: general, optimized for computation, GPU instances, optimized for memory, optimized for storage and micro-instances.

Instances are created from AMI (Amazon Machine Images) machine images.
An Amazon Machine Image (AMI) provides the information required to launch an instance. These machine images are similar to models configured with an operating system and other software, all forming the operating environment of the user.

An AMI includes the following:

  • A template for the root volume for the instance (for example, an operating system, an application server, and applications)
  • Launch permissions that control which AWS accounts can use the AMI to launch instances
  • A block device mapping that specifies the volumes to attach to the instance when it’s launched.

You can launch an instance from an existing AMI, customize the instance, and then save this updated configuration as a custom AMI. Instances launched from this new custom AMI include the customizations that you made when you created the AMI.

Users can select an AMI instance from AWS, the user community, or AWS Marketplace.

What is AWS Marketplace.

Amazon Marketplace Web Service (Amazon MWS) is an integrated web service API that helps Amazon sellers to programmatically exchange data on listings, orders, payments, reports, and more. Data integration with Amazon enables high levels of selling automation, which can help sellers grow their business. By using Amazon MWS, sellers can increase selling efficiency, reduce labor requirements, and improve response time to customers.

There are no fees associated with Amazon MWS, but to use the Amazon MWS API you must have an Amazon MWS-eligible seller account and you must register to use Amazon MWS.

With Amazon MWS, you can build applications for your own Amazon seller account. You can also build applications for other sellers to help them manage their online business. Using Amazon MWS you can create applications that look up products for sale, download orders for fulfillment, confirm shipment, and schedule and receive reports. These API operations are accessible by using a web service interface.

Though Amazon services is complex, Amazon EC2 and Amazon S3 are the two core Infrastructure as a Service (IaaS) services, which are used by cloud application solution developers worldwide.

Amazon web services stated as just a service for storing, backing up and archiving data and applications online (Amazon S3), but today you can utilize more than 70 Amazon services, including software, networking, analytics, mobile, database and others at affordable prices. New services are quickly provisioned, without the need for upfront capital expenses. This allows enterprises and others to access the building blocks they need to respond quickly to changing business requirements.
