Introduction to AWS
Amazon Web Services (AWS) is a comprehensive and widely adopted cloud computing platform provided by Amazon. It offers a broad set of cloud services, ranging from computing power to storage options, to cater to businesses and developers of all sizes. AWS allows users to run applications and services on Amazon’s infrastructure rather than investing in physical hardware and data centers. With a pay-as-you-go pricing model, AWS has become one of the most popular and scalable cloud platforms, serving businesses worldwide across various industries—and offering a wide range of Cloud Computing course to support skill development and adoption. As a cloud provider, AWS has revolutionized the IT industry by enabling businesses to deploy applications and scale resources quickly based on demand. AWS also provides services for artificial intelligence (AI), machine learning (ML), data analytics, security, and more. It has become the de facto standard for cloud infrastructure and continues to innovate in the rapidly evolving cloud space.

AWS Global Infrastructure
AWS operates in a global network of Regions, Availability Zones (AZs), and Edge Locations. The AWS global infrastructure is designed to provide customers with scalable, reliable, and low-latency cloud computing services worldwide. Here’s how AWS organizes its infrastructure:
- Regions: AWS divides its global network into geographic areas. An area is a physical location that consists of multiple Availability Zones. AWS has many regions worldwide, allowing customers to deploy resources closer to their users and ensure compliance with local data regulations.
- Availability Zones (AZs): Each region contains multiple Availability Zones, essentially isolated data centers within an area. These AZs are connected by low latency links, allowing users to build highly available applications across multiple AZs while benefiting from regional redundancy.
- Edge Locations: AWS also has a global network of edge locations primarily used for content delivery and caching services (e.g., Amazon CloudFront). These edge locations bring Top AWS Services and content closer to users, reducing latency and improving performance.
By offering this distributed infrastructure, AWS enables customers to deploy their applications globally while ensuring high availability, fault tolerance, and disaster recovery capabilities.
Core AWS Services Overview
AWS offers extensive services that cater to various business needs, from computing and storage to machine learning and artificial intelligence. The core categories of AWS services include:
- Compute: Services that allow you to run virtual machines, containers, and serverless applications.
- Storage: Services to store and manage data, including object storage, block storage, and file storage.
- Database: Managed database services that support relational, NoSQL, and in-memory databases.
- Networking: Tools for setting up secure and scalable networks, including VPC (Virtual Private Cloud), Load Balancer, and Route 53 (DNS).
- Security & Identity: Services like AWS Identity and Access Management (IAM) and AWS Key Management Service (KMS) for securing resources.
- Analytics: Big data services for analyzing large volumes of data and deriving insights using services like Amazon EMR, Athena, and Redshift.
- AI & Machine Learning: A wide range of services for building, training, and deploying Machine Learning Techniques and models using tools like Amazon SageMaker and Rekognition.
- Amazon S3 (Simple Storage Service): S3 is an object storage service that allows users to store and retrieve metadata such as documents, images, videos, and backups. It is designed for durability, scalability, and low-latency access.
- Amazon EBS (Elastic Block Store): EBS provides block level storage volumes for EC2 instances, allowing users to store data with low latency and high throughput. EBS is ideal for databases, enterprise applications, and workloads requiring persistent storage.
- Amazon EFS (Elastic File System): EFS provides scalable, cloud-native file storage that can be accessed concurrently from multiple AWS EC2 Instance. It’s suitable for workloads that require shared access to file-based data.
- Amazon Glacier: Glacier is a low-cost, long-term archiving and data backup storage service. It provides secure, durable storage at a fraction of the cost of other services but with slower retrieval times.
- AWS Identity and Access Management (IAM): IAM enables you to securely manage access to AWS services and resources. It allows you to create users, groups, and roles and define permissions for accessing AWS resources.
- AWS Key Management Service (KMS): KMS is a managed service that allows users to create and control encryption keys to encrypt data across AWS services.
- AWS Shield: Shield protects against Distributed Denial of Service (DDoS) attacks. AWS Shield Standard is included with all AWS accounts, while Shield Advanced provides enhanced protection for critical applications.
- AWS CloudTrail: CloudTrail enables governance, compliance, and auditing by providing logs of API calls on your AWS resources.
- AWS WAF (Web Application Firewall): WAF helps protect web applications from common security vulnerabilities like SQL injection and cross-site scripting (XSS).
- Pay-as-you-go: AWS’s most common pricing model, where users pay only for the resources they use, such as computing, storage, and data transfer.
- Reserved Instances: Users can reserve EC2 instances for a one- or three-year term at a discounted rate, providing cost savings for long-term workloads.
- Spot Instances: AWS EC2 Spot Instances allow users to purchase unused EC2 capacity at a reduced price, making it ideal for non-critical applications or batch-processing tasks.
- AWS Free Tier: The AWS Free Tier provides a limited set of services at no cost to new customers, allowing them to get hands-on experience with AWS services.
AWS Compute Services (EC2, Lambda, etc.)
AWS provides several computing services that allow users to run applications on its cloud infrastructure. Some of the most popular computing services are, Amazon EC2 (Elastic Compute Cloud), EC2 provides resizable compute capacity in the cloud. It allows users to launch virtual machines (instances) and scale them based on workload demands. EC2 provides flexibility in choosing the operating system, instance type, and size, making it a powerful and customizable option for running various applications.AWS Lambda, Lambda is a serverless computing service that lets you run code without provisioning or managing servers. Users can write functions triggered by events, such as changes in data or API calls, and Lambda automatically handles the scaling and execution. This makes it an efficient solution for event-driven applications. Amazon ECS (Elastic Container Service), ECS is a fully managed container orchestration service that allows users to run Docker containers. ECS can be integrated with other AWS services like EC2 or AWS Fargate, which provides container serverless computing. Amazon EKS (Elastic Kubernetes Service), EKS simplifies running Kubernetes clusters on AWS, providing a managed environment for deploying containerized applications.
