AWS Cloud Practitioner Overview

• Entry-level certification for understanding AWS Cloud basics.

Key Concepts

• Cloud Computing:
  • Infrastructure as a Service (IaaS): Provides virtualized computing resources (servers, storage, networking).
  • Platform as a Service (PaaS): Offers a platform for developing and running applications (runtime environments, databases, middleware).
  • Software as a Service (SaaS): Delivers software applications over the internet (email, CRM, productivity tools).
  • Deployment Models:
    • Public Cloud: Services are offered by a third-party provider over a public network.
    • Private Cloud: Infrastructure is dedicated to a specific organization and managed internally or by a third party.
    • Hybrid Cloud: Combines elements of both public and private clouds.

AWS Core Services

• Compute:

  • Amazon Elastic Compute Cloud (EC2): Provides virtual servers on demand.
  • AWS Lambda: Serverless computing service for running code without provisioning or managing servers.

• Storage:

  • Amazon Simple Storage Service (S3): Object storage for data of all types (images, videos, documents).
  • Elastic Block Storage (EBS): Persistent block-level storage volumes for EC2 instances.
  • Amazon Glacier: Archival storage for data rarely accessed.

• Database:

  • Amazon Relational Database Service (RDS): Managed relational databases (MySQL, PostgreSQL, Oracle).
  • Amazon DynamoDB: NoSQL database for high-performance applications.
  • Amazon Redshift: Data warehousing service for analyzing large datasets.

• Networking:

  • Amazon Virtual Private Cloud (VPC): Private network within AWS for isolating resources.
  • Amazon Route 53: DNS service for managing domain names and routing traffic.
  • Amazon CloudFront: Content Delivery Network (CDN) for distributing content globally.

Security and Compliance

• Shared Responsibility Model: AWS is responsible for security of the cloud, while customers are responsible for security in the cloud (data, applications, user access).
• Identity and Access Management (IAM): Controls user access to AWS resources.
• Compliance Frameworks: Ensure adherence to industry standards and regulations (GDPR, HIPAA).

Billing and Pricing

• Free Tier Services: Limited usage of select AWS services for free.
• Pricing Models:
  • Pay-as-you-go: Pay only for the resources used.
  • Reserved Instances: Purchase upfront commitment for a discounted rate, typically for longer-term usage.
• AWS Budgets and Cost Explorer: Tools for monitoring and managing AWS spending.

AWS Cloud Value Proposition

• Scalability: Easily expand or reduce resources based on demand.
• Flexibility: Provides services and tools for diverse workloads.
• Cost Efficiency: Reduces capital expenditure by offering a pay-as-you-go model.

AWS Global Infrastructure

• Regions and Availability Zones:
  • Multiple geographic regions worldwide to distribute resources.
  • Each region has multiple isolated locations called Availability Zones (AZs) within a region.

AWS Management Tools

• AWS CloudFormation:
  • Infrastructure as Code (IaC) for creating and managing AWS resources.
• AWS CloudWatch:
  • Monitors and manages AWS resources and applications.
• AWS Command Line Interface (CLI):
  • Used to manage AWS services through the command line

Best Practices

• AWS Well-Architected Framework: Guide for building secure, reliable, and cost-effective applications on AWS.
  • Five pillars: Security, Reliability, Performance Efficiency, Cost Optimization, Operational Excellence.
• Regularly review and optimize usage to control costs.

Exam Preparation

• Study Materials:
  • AWS Training and Certification resources.
  • Whitepapers on AWS services.
• Practice Exams: Simulate the actual exam format.
