Chapter 1: What is Cloud Computing?
Cloud computing is a model of delivering computing services over the internet. It allows users to access and store data, applications, and other computing resources online, rather than having them stored locally on a personal computer or server. Cloud computing provides numerous benefits, including scalability, flexibility, and cost-effectiveness. It has revolutionized the way businesses and individuals approach computing, data storage, and application development.
Chapter 2: History of Amazon Web Services
Amazon Web Services (AWS) is a subsidiary of Amazon that provides on-demand cloud computing platforms to individuals, companies, and governments. AWS was launched in 2002 as an extension of Amazon's own ecommerce platform. Initially, it provided basic computing resources, such as storage and database services. Over time, AWS has expanded its services to become one of the leading cloud computing providers, offering a broad range of services, including computing power, storage, databases, analytics, machine learning, and more.
Chapter 3: AWS Services Overview
AWS offers a wide range of services, including: Compute Services (EC2, Lambda, Elastic Beanstalk), Storage Services (S3, EBS, Elastic File System), Database Services (RDS, DynamoDB, DocumentDB), Security, Identity & Compliance (IAM, Cognito, Inspector), Analytics (Redshift, QuickSight, Lake Formation), Application Services (API Gateway, Elastic Load Balancer, CloudFront), and Machine Learning (SageMaker, Rekognition, Comprehend). These services can be used to build scalable, secure, and efficient applications.
Chapter 4: AWS Pricing and Cost Optimization
AWS pricing models are designed to provide flexibility and cost-effectiveness. The main pricing models are: On-Demand, Reserved Instances, and Spot Instances. AWS also provides tools and services to help optimize costs, such as Cost Explorer, Budgets, and Reserved Instance Recommendations. Additionally, AWS offers a free tier for many of its services, allowing users to try and experiment with AWS without incurring significant costs.
Chapter 5: AWS Security Fundamentals
Security is a top priority for AWS. AWS provides a secure global infrastructure, with built-in security features and services. The AWS Shared Responsibility Model defines the security responsibilities between AWS and its customers. AWS provides tools and services to help customers secure their resources, including IAM, Cognito, Inspector, and CloudWatch. Customers are responsible for securing their resources and applications in the cloud.
Chapter 6: AWS IAM and Access Management
AWS Identity and Access Management (IAM) is a service that helps securely control access to AWS resources. IAM allows users to create and manage AWS users and groups, and use permissions to control access to AWS resources. IAM also provides features like multi-factor authentication, password policies, and access reporting.
Chapter 7: AWS Storage Services
AWS provides a range of storage services, including S3, EBS, Elastic File System, and Storage Gateway. These services offer durable, highly available, and scalable storage options for applications and data. S3 is an object store that can be used for static website hosting, data lakes, and content delivery. EBS provides block-level storage for EC2 instances.
Chapter 8: AWS Database Services
AWS provides a range of database services, including relational databases (RDS), NoSQL databases (DynamoDB), and database migration services (Database Migration Service). RDS supports popular database engines like MySQL, PostgreSQL, Oracle, and SQL Server. DynamoDB is a fast, fully managed NoSQL database service.
Chapter 9: AWS Analytics and Machine Learning
AWS provides a range of analytics and machine learning services, including Redshift, QuickSight, Lake Formation, SageMaker, Rekognition, and Comprehend. These services allow users to analyze and gain insights from their data, and build intelligent applications that can see, hear, and understand.
Chapter 10: AWS Best Practices and Architectures
AWS provides guidelines and best practices for designing and deploying scalable, secure, and efficient applications. The AWS Well-Architected Framework provides a set of best practices for designing and operating reliable, secure, and high-performing workloads in the cloud. AWS also provides reference architectures for common use cases, such as web applications, microservices, and data lakes.
