AWS Introduction

You need to have a solid understanding of key components on AWS services, best practices for integrating with Java applications, and the ability to architect a scalable, efficient, and secure solution in the cloud.

Prerequisites

JDK 17+ is good to have.

What is AWS ?

AWS stands for Amazon Web Services. It is a comprehensive and evolving cloud computing platform provided by Amazon.

AWS offers a wide range of cloud services, including computing power, storage, networking, databases, machine learning, analytics, security, and more. These services are available on-demand, allowing businesses and individuals to access and utilize computing resources without the need for owning and managing physical hardware.

It offers different types of cloud services that allows businesses and developers to build, deploy and manage applications and services in a flexible and and cost effective manner.

Some of the key services provided by AWS include:

  1. Compute Services: AWS offers various compute services such as Amazon EC2 (Elastic Compute Cloud) for scalable virtual servers, AWS Lambda for serverless computing, and Amazon ECS (Elastic Container Service) for container orchestration.
  2. Storage Services: AWS provides multiple storage options like Amazon S3 (Simple Storage Service) for object storage, Amazon EBS (Elastic Block Store) for persistent block storage, and Amazon Glacier for long-term archival storage.
  3. Database Services: AWS offers managed database services like Amazon RDS (Relational Database Service) for relational databases, Amazon DynamoDB for NoSQL databases, and Amazon Redshift for data warehousing.
  4. Networking: AWS provides networking services such as Amazon VPC (Virtual Private Cloud) for isolated cloud resources, Amazon Route 53 for domain name system (DNS) management, and AWS Direct Connect for dedicated network connections.
  5. Machine Learning and AI Services: AWS offers services like Amazon SageMaker for building, training, and deploying machine learning models, Amazon Comprehend for natural language processing (NLP), and Amazon Rekognition for image and video analysis.
  6. Analytics: AWS provides services such as Amazon EMR (Elastic MapReduce) for big data processing, Amazon Redshift for data warehousing and analytics, and Amazon Athena for interactive query analysis.
  7. Security and Identity: AWS offers security services like AWS Identity and Access Management (IAM) for managing user access, Amazon GuardDuty for threat detection, and AWS WAF (Web Application Firewall) for web application security.

These are just a few examples of the extensive range of services offered by AWS. It has become a popular choice for businesses of all sizes due to its scalability, flexibility, reliability, and cost-effectiveness in managing cloud infrastructure and services.

Cloud Computing Basics

Cloud computing shifts the traditional model of owning physical hardware and infrastructure to a model where resources are provided and accessed over the internet.

Now this offers scalability, flexibility, and cost efficiency.

Key Features :

  • On-Demand resources – you can quickly provision and release resources as needed.
  • Scalability – It allows you to scale applications up or down based on demand.
  • Flexibility – You can be able to choose from different operating systems, programming languages, databases, and more.
  • Global Reach – data centers and multiple regions around the world.
  • Security – offers robust security features compliance with different industry standards.

AWS Service Categories

There are different service categories for AWS.

  • Compute – Amazon EC2 – provides virtual servers for computing power.
  • Storage –
    • Amazon S3 – offers scalable object storage
    • Amazon EBS – Elastic Block Store – provides block storage
  • Databases – Amazon RDS or Relational Database Service and Amazon DynamoDB offers managed database solution.
  • Networking – Amazon VPC allows you to create isolated networks in the cloud.
  • Developer tools – AWS Code Deploy, Assist, and deploying applications.
  • Security –
    • AWS IAM – controls access to resources
    • AWS Shield – provides DDoS Protection

We can say that Amazon Web Services is a powerhouse and a world of cloud computing. Because it provides a different services and tools to empower developers and businesses.
