  • [AWS CCP] 14, AWS IAM Fundamentals
    This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams.
    In this episode you will learn:
    - The root user should be secured with MFA and not used for daily tasks; always use IAM users with specific permissions.
    - IAM policies are JSON documents that define permissions and can be attached to users, groups, or roles to manage access.
    - The principle of least privilege is a core security concept that involves granting only the minimum permissions required for a task.
    - IAM roles provide temporary credentials and are the secure way to grant permissions to AWS services like EC2, avoiding the use of long-term access keys.
    - For the exam, remember that users are for people needing permanent credentials, while roles are for services or temporary access scenarios.

  • [AWS CCP] 13, Shared Responsibility Model
    This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams.
    In this episode you will learn:
    - The core distinction between AWS's responsibility (security OF the cloud) and the customer's responsibility (security IN the cloud).
    - For IaaS services like EC2, the customer is always responsible for guest OS patching and security group configuration.
    - In a PaaS model like RDS, AWS manages database engine patching, but the customer still controls data access and encryption.
    - For SaaS services like S3, the customer's primary responsibilities are managing data and configuring access permissions through policies.
    - A simple mnemonic for the exam: 'If you can configure it, you are responsible for securing it.'

  • [AWS CCP] 12, Containers on AWS
    This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams.
    In this episode you will learn:
    - A Docker container is a portable package with an application's code and all its dependencies.
    - Amazon ECS is the AWS-native, fully managed service for orchestrating Docker containers.
    - Amazon EKS is the managed service for running Kubernetes, ideal for portability and existing Kubernetes users.
    - AWS Fargate is a serverless compute engine for both ECS and EKS that removes the need to manage EC2 instances.
    - Choose containers for portability, serverless (Lambda) for event-driven tasks, and EC2 for full OS control.

  • [AWS CCP] 11, Serverless Computing Concepts
    This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams.
    In this episode you will learn:
    - Serverless means you don't provision or manage servers; AWS handles all underlying infrastructure management.
    - AWS Lambda is the core serverless compute service that runs code in response to events from over 200 AWS services.
    - The serverless pay-per-use model is most cost-effective for workloads with unpredictable or sporadic traffic.
    - A complete serverless architecture often includes Lambda (compute), API Gateway (APIs), DynamoDB (NoSQL database), and S3 (object storage).
    - A common exam scenario involves choosing between Lambda for event-driven tasks and EC2 for long-running, consistent workloads.

    - The Business support plan is the minimum tier required to unlock the complete set of AWS Trusted Advisor checks.
    - A dedicated Technical Account Manager (TAM) is an exclusive feature of the top-tier Enterprise support plan.
    - Response times are a key differentiator, with the Enterprise plan offering a less-than-15-minute response for critical issues.
    - The Enterprise On-Ramp plan provides access to a pool of TAMs, unlike the dedicated TAM in the full Enterprise plan.

    - How Multi-AZ deployments serve as the foundation for building resilient applications in AWS.
    - Why Amazon RDS Multi-AZ is a prime example of a fault-tolerant service.
    - That RPO (Recovery Point Objective) measures the maximum acceptable data loss in terms of time.

  • [AWS CCP] 8, Elasticity and Scalability
    This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams.
    In this episode you will learn:
    - Elasticity is about automatically adapting to variable demand, while scalability is about handling overall growth.
    - Horizontal scaling (adding more instances) is the preferred AWS method for achieving high availability and fault tolerance.
    - Vertical scaling (increasing instance size) is simpler but creates a single point of failure, making it a common exam distractor.
    - Elastic Load Balancing (ELB) distributes traffic, while Auto Scaling Groups (ASG) automatically add or remove instances.
    - Exam scenarios involving unpredictable traffic spikes are best solved with the combination of ELB and ASG for horizontal scaling.

  • [AWS CCP] 7, AWS Cloud Adoption Framework
    This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams.
    In this episode you will learn:
    - The AWS CAF is a strategic framework to reduce business risk in cloud adoption, not a specific AWS service.
    - The six perspectives are grouped into Business Capabilities (Business, People, Governance) and Technical Capabilities (Platform, Security, Operations).
    - The Business perspective ensures cloud investments align with business outcomes like ROI and strategic goals.
    - A common exam trap is confusing the Governance perspective (program management, risk mitigation) with the Security perspective (data confidentiality, integrity, and availability).
    - The People perspective directly addresses challenges related to staff training, skills gaps, and organizational change.
