Section 1.1 Amazon S3

Amazon S3, or Simple Storage Service, offers a highly durable and accessible storage solution. Data is stored as objects—essentially files along with any associated metadata—within containers known as Buckets. Each account can have up to 100 buckets, and every object is identified by a unique key, referred to as the Object Key.

In essence, Amazon S3 functions as a hash map that links the bucket to the object key, uniquely identifying each object.

Section 1.2 Amazon EC2

Amazon EC2, short for Elastic Compute Cloud, delivers scalable computing resources in the cloud. Users can create virtual computing environments known as Instances, tailored to specific requirements such as CPU, memory, and networking capabilities. These configurations, referred to as Instance types, allow for flexibility in resource allocation.

As an example, the m5.large Instance type provides 8 GB of memory and network speeds of up to 10 Gbps.

Section 1.3 Amazon Lambda

AWS Lambda enables users to execute code or scripts without the need to provision or manage servers. Billing is based solely on the compute time used while the code is active.

For instance, if developing an image recognition machine learning service, Lambda can automatically run code to preprocess an image upon upload, ensuring seamless integration.

Section 1.4 Amazon SQS

Simple Queue Service (SQS) is a cloud-based messaging service that facilitates the integration of distributed system components. Producers send messages to SQS, which can be processed by consumers in a first-in-first-out (FIFO) manner. Once consumed, messages are discarded, and there is no limit on the volume of messages that can be enqueued, stored, or processed.

Section 1.5 Amazon Kinesis

Kinesis is a powerful service that allows users to ingest, buffer, and process streaming data in real-time. Unlike SQS, where messages are removed after consumption, Kinesis supports multiple consumers, making it ideal for various real-time data processing needs.

For further insights into the differences between SQS and Kinesis, you can refer to detailed comparisons available online.

Section 1.6 Amazon Cognito

Cognito simplifies the implementation of customer identity management, including authentication and authorization, for web and mobile applications. It comprises two primary components:

• User Pools: Offering sign-up and sign-in options for users
• Identity Pools: Granting users access to various AWS services

Section 1.7 DynamoDB

DynamoDB is a highly scalable and durable NoSQL database service that supports both key-value and document data structures, utilizing hashing and B-trees for efficient management.

Section 1.8 Amazon CloudFront

Amazon CloudFront is a content delivery network (CDN) that accelerates the distribution of both static and dynamic web content, ensuring low latency and high performance through its edge locations.
