AWS Certified Cloud Practitioner – 21 Day Builder Sprint

AWS is one of the most widely used cloud platforms, but beginners often make mistakes that can lead to security risks or unexpected costs. Before you start learning and creating resources on AWS, it's important to set up your account properly.

The Cloud Computing Revolution refers to the shift from traditional on-premises IT infrastructure to cloud-based services delivered over the internet. Instead of purchasing and maintaining physical servers, organizations can access computing resources such as storage, databases, networking, and software on demand from cloud providers like AWS. This transformation has enabled businesses to reduce costs, scale resources quickly, innovate faster, and deploy applications globally with greater flexibility and efficiency.

AWS Global Infrastructure is the worldwide network of data centres and cloud resources that power services offered by Amazon Web Services (AWS). It consists of multiple geographically distributed AWS Regions, which contain several isolated Availability Zones connected through high-speed networking. This infrastructure enables organizations to deploy applications closer to users, achieve high availability, improve fault tolerance, meet compliance requirements, and scale workloads globally with low latency and strong security.

Cloud Architecture Principles are best practices that guide the design and operation of cloud-based systems. They focus on building applications that are secure, reliable, scalable, efficient, and cost-effective. Key principles include designing for failure, implementing elasticity, automating processes, using loose coupling, and leveraging managed services to improve performance and reduce operational overhead. These principles help organizations maximize the benefits of cloud computing while maintaining high availability and resilience.

Step by step description on how to create a account on AWS.

The AWS Shared Responsibility Model defines the security responsibilities of both AWS and its customers. AWS is responsible for the security of the cloud, including the physical infrastructure, hardware, networking, and facilities that run AWS services. Customers are responsible for security in the cloud, which includes managing their data, configuring security settings, controlling access through IAM, and securing applications and operating systems they deploy. Understanding this division of responsibilities is essential for maintaining a secure cloud environment.

AWS Identity and Access Management (IAM) is a service that enables organizations to securely manage access to AWS resources. IAM allows administrators to create and manage users, groups, roles, and policies, ensuring that only authorized individuals and services can access specific resources. By following the principle of least privilege, IAM helps improve security by granting only the permissions necessary to perform required tasks. It is a core security service.

Amazon EC2 (Elastic Compute Cloud) is a web service that provides scalable virtual servers, known as instances, in the AWS Cloud. It allows users to quickly launch, configure, and manage computing resources without investing in physical hardware. EC2 offers flexibility in choosing operating systems, instance types, storage, and networking configurations, enabling organizations to run applications securely and scale resources based on demand. It is a fundamental AWS compute service

The-Modern-Way-to-Build-Cloud-Applications is a software engineering framework that unifies infrastructure provisioning and application code into a single workflow. It allows developers to define and manage cloud architecture using standard programming languages like TypeScript, Python, or Go. By leveraging containers, serverless functions, and managed services, this approach ensures environment consistency and accelerates delivery. It enables teams to scale applications seamlessly, representing a fundamental shift to dynamic, software-defined cloud engineering.

Amazon S3 (Simple Storage Service) is a web service that provides highly durable and scalable object storage in the AWS Cloud. It allows users to securely store and retrieve an unlimited amount of data, from anywhere on the web, without managing physical infrastructure S3 offers flexibility across various storage classes, automated lifecycle management, and robust access controls, enabling organizations to optimize costs and seamlessly scale data resources based on demand.

AWS Block, File, and Snow Family storage services provide versatile storage types and physical migration devices in the AWS Cloud. They allow users to provision high-performance block volumes, set up scalable shared file systems, or transport massive datasets offline without complex physical infrastructure. Offering options like EBS, EFS, and physical Snow appliances, this portfolio provides extreme flexibility to balance cost, performance, and bandwidth constraints, enabling organizations to optimize data management and securely scale on demand.

This lesson covers the fundamentals of AWS networking, including VPCs, public and private subnets, Internet and NAT Gateways, Security Groups, NACLs, route tables, VPC Endpoints, and global networking services. It also explains how to build secure, scalable AWS network architectures and prepares learners for networking-related AWS Cloud Practitioner exam questions.

AWS Database Services provide a portfolio of fully managed, purpose-built database engines in the AWS Cloud. They allow users to quickly deploy, configure, and scale specialized databases without investing in physical hardware or administrative management. Offering flexible options like RDS, Aurora, serverless DynamoDB, and Redshift, this portfolio enables organizations to run applications securely, offload complex queries, and scale operational or analytical workloads based on demand.

AWS Application Integration Services is a suite of web services that provides messaging and workflow routing, such as SQS and SNS, in the AWS Cloud. It allows users to quickly connect, configure, and decouple independent components without investing in physical hardware. These services offer flexibility across point-to-point queues, pub/sub topics, and serverless event buses, enabling organizations to run applications securely and scale resources based on demand.

AWS Security and Protection Services is a web service suite that provides threat detection, vulnerability assessment, and compliance monitoring in the AWS Cloud. It allows users to quickly deploy, configure, and manage security tools like GuardDuty, Inspector, WAF, and Shield without investing in physical hardware. This arsenal offers flexibility across network defense, automated encryption key management, and data discovery, enabling organizations to run applications securely and scale threat protection based on demand.

AWS Monitoring and Infrastructure as Code Services is a web service suite that provides resource performance monitoring, API audit logging, and automated resource deployment in the AWS Cloud. It allows users to quickly launch, configure, and manage operations tools like CloudWatch, CloudTrail, and CloudFormation without investing in physical hardware. This portfolio offers flexibility across real-time metrics, infrastructure templates, and best-practice optimization checks, enabling organizations to run applications securely and scale resource management based on demand.

Real-world AWS environments are rarely built by hand. Large organizations build infrastructure through code, scale it automatically based on demand, let employees sign in once across many accounts, and govern every account with consistent rules. This chapter covers the five services that make this possible.

In today's session, we explore AWS AI/ML and Analytics Services, one of the most important topics for the AWS Certified Cloud Practitioner exam.

You'll learn the difference between ready-made AI services and custom machine learning, understand when to use each AWS AI service, and master the AWS analytics pipeline from data ingestion to visualization.
