What is Amazon Web Services

  • Amazon Web Services (AWS) is a subsidiary of Amazon.com that provides an on-demand cloud computing platform.
  • It stands out in the cloud computing market for offering a wide range of services and features, surpassing many other cloud providers.
  • It covers computing resources, storage, and databases, machine learning, AI, data lakes & analytics, and the Internet of Things (IoT).

Key points about AWS :

  • Virtual Computing: AWS enables the partitioning of virtual servers, allowing users to create and manage multiple virtual machines on a single physical server.

  • IaaS (Infrastructure as a Service): AWS offers fundamental computing resources over the internet => Users can access and manage these resources without needing to invest in physical hardware.

  • Other Cloud Computing Services: Google Cloud Platform and Microsoft Azure. These platforms provide a range of services for businesses and individuals to deploy and manage applications, data, and services.

  • Comparison with On-Premise Data Centers: Contrasting AWS with on-premise data centers (IDC), which are maintained within an organization’s own facilities.

IAM - Identity and Access Management

  • Identity and Access Management (IAM) provides a framework for controlling access to your AWS resources
  • It allows you to centrally manage permissions and access controls for users, groups, and roles across your entire AWS infrastructure.
  • It’s important to note that IAM is not specific to any AWS region, meaning the configurations and permissions apply globally.

EC2 - Elastic Compute Cloud

Creating an instance

  • This means renting a virtual computer that is configured based on a selected AMI.
  • This configuration encompasses factors such as OS, CPU, RAM allocation, storage setup, and runtime environment.
  • Users can customize these parameters according to their specific needs.

EC2 Instance Types

  • EC2 instance types cater to various performance characteristics, making them suitable for different purposes.

  • Depending on your focus and requirements, you can choose an instance type.

  • Examples…

    1. Compute-Optimized: Prioritizing CPU performance, making them suitable for compute-intensive tasks.
    2. Memory-Optimized: Emphasizing high RAM capacity, making them ideal for memory-intensive applications.
    3. Storage-Optimized: Demanding substantial storage capacity and high throughput.
