Amazon Web Services

AWS is an abbreviation for Amazon Web Services, which requires no formal introduction given its enormous popularity. Amazon Web Services is the market’s leading cloud provider. It provides over 170 AWS services to developers, allowing them to access them from anywhere at any time. Web Services launched its first web services in 2002, using internal infrastructure built by to manage its online retail operations. It began providing it’s defining IaaS services in 2006. AWS was among the first to introduce a pay-as-you-go cloud computing model, which scales to provide users with computing, storage, or throughput as needed.

provides a wide range of tools and solutions for businesses and software developers that can be used in data centers in over 190 countries. AWS services are available to government agencies, educational institutions, non-profits, and private organizations.

How Does AWS Work?

AWS is divided into different services, each of which can be configured differently depending on the needs of the user. Users can view AWS service configuration options and individual server maps.

The AWS portfolio includes over 200 services, including computing, databases, infrastructure management, application development, and security. These services are classified as follows:

  • compute
  • storage
  • databases
  • data management
  • migration
  • hybrid cloud
  • networking
  • development tools
  • management
  • monitoring
  • security
  • governance
  • big data management
  • analytics
  • artificial intelligence (AI)
  • mobile development
  • messages and notification

Applications of AWS

Here are some brief explanations of how AWS is used in these areas:


AWS offers a wide range of services across numerous data centers located in 87 availability zones (AZs) around the world. An AZ refers to a place comprising multiple physical data centers, while a region consists of AZs in close geographic proximity linked by high-speed networks.

Businesses choose one or more AZs for various reasons, including compliance requirements, proximity to customers, and optimizing availability. For instance, an AWS user can create virtual machines (VMs) and replicate data in different AZs to establish a robust cloud infrastructure that remains resilient in the face of server or data center failures.

Amazon Elastic Compute Cloud (EC2) is a service that offers virtual servers, known as EC2 instances, for computing capacity. It offers a diverse selection of instance types catering to specific workload demands and applications, such as memory-intensive tasks or accelerated computing requirements. Additionally, AWS provides Auto Scaling, a tool that dynamically adjusts capacity to maintain optimal instance performance and health.


Amazon Simple Storage Service (S3) offers scalable storage for data backup, analysis, and collection. IT professionals store data and files as S3 objects, which can be up to five gigabytes in size, within S3 buckets to maintain organization. Businesses can optimize costs by utilizing S3’s Infrequent Access storage class or by leveraging Amazon Glacier for long-term, low-cost storage.

For persistent data storage with EC2 instances, Amazon Elastic Block Store provides block-level storage volumes. Additionally, Amazon Elastic File System offers managed cloud-based file storage.

To facilitate data migration to the cloud, businesses can employ storage transport devices like AWS Snowball, Snowball Edge, and Snowmobile. Alternatively, they can use AWS Storage Gateway to enable on-premises applications to access cloud data.

Internet of Things (IoT)

AWS also offers a number of services that facilitate IoT deployments. The AWS IoT service provides a back-end platform for managing IoT devices and ingesting data into other AWS storage and database services.

The Amazon IoT Button is a piece of hardware that allows for limited IoT functionality and AWS IoT. Greengrass extends AWS compute capabilities to the Internet of Things devices.

Augmented Reality (AR) And Virtual Reality (VR)

AWS provides AR and VR development tools in the form of Babylon.js and AWS Simplify. Users can use Babylon.js to create AR and VR applications without knowing how to code or create 3D graphics. Users can also test and publish applications in-browser using the service. Babylon.js can be used in the following situations:

  • 3D web applications
  • e-commerce
  • sales applications
  • marketing
  • online education
  • manufacturing
  • training simulations
  • gaming

Messages And Notifications

AWS messaging services enable users and applications to communicate with one another. Amazon Simple Queue Service (SQS) is a managed message queue that sends, stores, and receives messages between distributed application components to ensure that the parts of an application work as intended.

A business can use Amazon Simple Notification Service (SNS) to send publish-subscribe messages to endpoints such as end users or services. SNS includes a mobile messaging feature that allows for push notifications to mobile devices. IT professionals and marketers can use Amazon Simple Email Service to send and receive emails.

Game Development

AWS can also be used to develop games. They are used by large game development companies, such as Ubisoft’s For Honor. AWS can offer services for every stage of a game’s lifecycle.

For example, offers developer back-end services, analytics, and developer tools like Amazon Lumberyard, which help developers create 3D games. Back-end services such as Amazon GameLift aid in the development, deployment, and scaling of a developer’s platform, as well as the defense against DDoS attacks.

Mobile Development

AWS Mobile Hub provides a set of tools and services for mobile app developers. The AWS Mobile SDK, which provides code samples and libraries, is one of these tools.

A mobile app developer can also use Amazon Cognito to manage user access to mobile apps, as well as Amazon Pinpoint to send push notifications to app end users and analyze their effectiveness.

Migration And Hybrid Cloud

AWS offers a range of tools and services to assist users in migrating applications, databases, servers, and data to its public cloud. The AWS Migration Hub provides a central location for monitoring and managing migrations from on-premises to the cloud. In the cloud environment, the EC2 Simple Systems Manager aids IT teams in configuring both on-premises servers and AWS instances.

Amazon has established partnerships with various technology vendors to simplify hybrid cloud deployments. VMware Cloud on AWS enables the utilization of VMware’s software-defined data center technology within the AWS cloud. Another collaboration with Red Hat resulted in Red Hat Enterprise Linux for Amazon EC2, extending Red Hat’s operating system to the AWS cloud.

Once the migration of applications, databases, servers, and data is complete, either to the cloud or a hybrid environment, tools such as AWS Outposts can provide AWS services and infrastructure across multiple environments.
