AWS
AWS (Amazon Web Services) is a comprehensive cloud computing platform provided by Amazon. It offers a vast range of cloud services that enable businesses to build, deploy, and manage applications and services with flexibility, scalability, and reliability. AWS provides services such as compute (EC2), storage (S3), databases (RDS, DynamoDB), networking (VPC), serverless computing (Lambda), AI and machine learning (Amazon Rekognition, SageMaker), big data processing (Amazon Redshift, EMR), and many more.
Module 1: AWS Fundamentals
Introduction to AWS
AWS (Amazon Web Services) is a comprehensive and broadly adopted cloud platform provided by Amazon. It offers over 200 fully-featured services from data centers globally. These services include computing power, storage options, networking and databases, analytics, machine learning and artificial intelligence (AI), Internet of Things (IoT), security, and application development, deployment, and management.
Setting up an AWS account
To start using AWS services, you first need to create an AWS account. This includes providing your email address and credit card details. AWS offers a Free Tier with certain services free for 12 months, up to a specific usage limit.
AWS Management Console
The AWS Management Console is a web application for managing Amazon Web Services. The console provides an intuitive user interface for performing many AWS tasks. These include working with Amazon S3 buckets, launching and connecting to Amazon EC2 instances, setting up Amazon RDS DB instances, and more.
Understanding AWS Global Infrastructure
AWS is structured into Regions and Availability Zones. Each Region is a separate geographic area with multiple, isolated locations known as Availability Zones. AWS offers services from data centers in many regions around the world.
Module 2: Core AWS Services
Amazon EC2 (Elastic Compute Cloud)
Amazon EC2 is a web-based service that allows businesses to run application programs in the Amazon Web Services public cloud. EC2 allows scalable deployment of applications by providing a Web service through which a user can boot an Amazon Machine Image to create a virtual machine, which Amazon calls an 'instance', containing any software desired.
Amazon S3 (Simple Storage Service)
Amazon S3 is an object storage service that offers industry-leading scalability, data availability, security, and performance. S3 is designed for 99.999999999% (11 9's) of durability, and it stores data for millions of applications for companies all around the world.
Amazon RDS (Relational Database Service)
Amazon RDS makes it easy to set up, operate, and scale a relational database in the cloud. It provides cost-efficient and resizable capacity while automating time-consuming administration tasks such as hardware provisioning, database setup, patching, and backups.
Amazon Lambda
AWS Lambda lets you run code without provisioning or managing servers. You pay only for the compute time you consume - there is no charge when your code is not running. With Lambda, you can run code for virtually any type of application or backend service.
Module 3: Networking and Security on AWS
Amazon VPC (Virtual Private Cloud)
Amazon VPC lets you provision a logically isolated section of the AWS Cloud where you can launch AWS resources in a virtual network that you define. You have complete control over your virtual networking environment, including the selection of your own IP address range, the creation of subnets, and the configuration of route tables and network gateways.
AWS IAM (Identity and Access Management)
IAM is a web service that helps you securely control access to AWS resources. You use IAM to control who is authenticated (signed in) and authorized (has permissions) to use resources. IAM allows you to manage users and their level of access to the AWS console.
AWS Security Groups
A security group acts as a virtual firewall for your instance to control inbound and outbound traffic. When you launch an instance in a VPC, you can assign up to five security groups to the instance.
AWS WAF (Web Application Firewall)
AWS WAF is a web application firewall that helps protect your web applications or APIs against common web exploits that may affect availability, compromise security, or consume excessive resources. AWS WAF gives you control over how traffic reaches your applications by enabling you to create security rules that block common attack patterns.
Module 4: Advanced AWS Services and Best Practices
AWS Serverless Framework
The AWS Serverless Application Model (SAM) is an open-source framework for building serverless applications. It extends AWS CloudFormation to provide a simplified way of defining the Amazon API Gateway APIs, AWS Lambda functions, and Amazon DynamoDB tables needed by your serverless application.
AWS Auto Scaling
AWS Auto Scaling monitors your applications and automatically adjusts capacity to maintain steady, predictable performance at the lowest possible cost. It provides a simple, powerful user interface that lets you build scaling plans for resources including Amazon EC2 instances and Spot Fleets, Amazon ECS tasks, Amazon DynamoDB tables and indexes, and Amazon Aurora Replicas.
AWS Best Practices
Some of the best practices for AWS include: designing for failure so you're resilient to failure, using multiple Availability Zones for high availability, securing your applications by using IAM and VPC, optimizing for cost, and enabling CloudTrail for auditing.
