Amazon Web Services AWS, Pricing, Core Services, Advantages, Uses

Amazon Web Services AWS, Pricing, Core Services, Advantages, Uses AWS stands for Amazon Web Services. AWS service is provided by Amazon which uses distributed IT infrastructure to provide multiple IT resources available on demand. It provides various services such as Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Packaged Software as a Service (SaaS). Amazon launched the cloud computing platform AWS to allow many organisations to take advantage of reliable IT infrastructure.

Amazon Web Services AWS

Amazon Web Services (AWS) is a comprehensive and widely adopted cloud platform provided by Amazon. It offers a vast array of cloud services that include computing power, storage, and networking, as well as tools for machine learning, analytics, security, and IoT (Internet of Things). Here’s a detailed overview of AWS.

Core Services of AWS


Amazon EC2 (Elastic Compute Cloud): Provides scalable virtual servers for running applications.
AWS Lambda: A serverless compute service that runs code in response to events and automatically manages the underlying compute resources.
Amazon ECS (Elastic Container Service) and EKS (Elastic Kubernetes Service): Services for deploying, managing, and scaling containerized applications.


Amazon S3 (Simple Storage Service): Highly scalable object storage with a range of management features.
Amazon EBS (Elastic Block Store): Provides block storage for use with Amazon EC2 instances.
Amazon Glacier: Low-cost cloud storage service for data archiving and long-term backup.


Amazon RDS (Relational Database Service): Managed relational database service supporting multiple database engines.
Amazon DynamoDB: Fully managed NoSQL database service.
Amazon Redshift: Data warehousing service that makes it simple and cost-effective to analyze all your data.


Amazon VPC (Virtual Private Cloud): Enables you to provision a logically isolated section of the AWS cloud.
AWS Direct Connect: Establishes a dedicated network connection from your premises to AWS.

Developer Tools:

AWS CodeDeploy: Automates code deployments to any instance, including Amazon EC2 and on-premises servers.
AWS CodePipeline: Continuous integration and delivery service for fast and reliable application and infrastructure updates.

Advanced Services of Amazon Web Services AWS

Machine Learning & AI:

Amazon SageMaker: Fully managed service that provides every developer and data scientist with the ability to build, train, and deploy machine learning models quickly.
AWS Rekognition: Adds image and video analysis to applications.


Amazon EMR (Elastic MapReduce): Managed Hadoop framework for big data processing.
Amazon Kinesis: Platform for real-time streaming data.


AWS IoT Core: Managed cloud service that lets connected devices easily and securely interact with cloud applications and other devices.

Security & Identity:

AWS Identity and Access Management (IAM): Enables you to manage access to AWS services and resources securely.
AWS Key Management Service (KMS): Makes it easy to create and control the encryption keys used to encrypt your data.

AWS Global Infrastructure

AWS operates in multiple geographic regions across the world, each consisting of multiple availability zones (data centers). This infrastructure is designed to provide high availability, redundancy, and low latency.

AWS Pricing

AWS uses a pay-as-you-go pricing model, allowing users to pay only for the services they use without requiring long-term contracts or complex licensing. It also offers a free tier with limited usage for new users.

Uses of Amazon Web Services AWS

  • A small manufacturing organization can leverage its IT expertise to grow its business by leaving its IT management to AWS.
  • A large business that spans the globe can use AWS to train a distributed workforce.
  • An architecture consulting company can use AWS to obtain high-resolution renderings of construction prototypes.
  • A media company can use AWS to deliver a variety of content, such as eBooks or audio files, to users around the world.

Advantages of Amazon Web Services AWS

  • Flexibility
  • Cost effictiveness
  • Scalability
  • Security

How Works Amazon Web Services AWS?

AWS generates its own network infrastructure by locating datacenters in multiple regions around the world. Its global infrastructure serves as the backbone for the operations and services offered through AWS. It allows users to create secure environments using Amazon VPC (Virtual Private Cloud). Services like Amazon EC2 and Amazon S3 are essential for using compute and storage services with elastic scaling.

It supports dynamic scaling of applications with services like Auto Scaling and Elastic Load Balancing (AWS ELB). It provides a user-friendly AWS Management Console that allows users to seamlessly configure and manage AWS services.

Applications of Amazon Web Services AWS

  • Netflix
  • Airbnd
  • NASA’s Jet Propulsion Laboratory
  • Capital One

Amazon Web Services AWS Cloud Computing Models

IaaS (Infrastructure as a Service) in AWS

Flexibility and Control: IaaS provides virtualized computing resources such as VMs, storage, and networks, allowing users to have control over operating systems and applications.

Reducing Hardware Costs: IaaS provides cost savings to businesses by eliminating physical infrastructure investments, making it cost-effective.

Scalability of Resources: Cloud helps in scaling up or down hardware resources as per demand, thereby providing optimal performance with cost efficiency.

Example: VPC, EC2, EBS.

PaaS (Platform as a Service) in AWS

Simplifying development: Platform as a Service provides a system for application development by abstracting away the infrastructure involved. It helps developers to focus completely on the application logic (code) and background operations are completely managed through the AWS platform.

Increasing efficiency and productivity: PaaS reduces the management of infrastructure overhead, speeds up execution times and brings updates to market faster by streamlining the development process.

Automating Scaling: By managing resource scaling, program workload efficiency is guaranteed through PaaS.

Example: RDS, EMR, Elastic Search.

SaaS (Software as a Service) in AWS

Collaboration and Access: Software as a Service (SaaS) helps users to easily access applications without the need for local installation. It is completely managed through AWS software as a service over the internet which promotes seamless collaboration and ease of access.

Automation of Updates: SaaS providers manage software maintenance operations with automated new updates, keeping users updated with new features and security patches.

Cost Efficiency: SaaS serves as a cost-effective solution by reducing IT support overhead by eliminating the need for individual software licenses.

Example:, Web-based email, Office 365.

Use Cases of AWS

  • Web Hosting: Scalable web hosting services for websites and applications.
  • Big Data Processing: Tools for processing large data sets efficiently.
  • Disaster Recovery: Solutions for disaster recovery and data backup.
  • Mobile and Web Apps: Services to build, deploy, and scale mobile and web applications.
  • Enterprise IT: Solutions for enterprise-level IT needs, including migration and hybrid cloud deployments.

AWS continues to be a leader in the cloud services industry, offering an extensive suite of tools and services that cater to a wide variety of use cases, from startups to large enterprises.
