    Study Notes

    Cost Governance

    • Architecture optimization is a best practice for cost governance, which focuses on refining workloads to be more cost-conscious and create better architected systems.

    Hosting Databases

    • To host MySQL databases on AWS with full control over the operating system, database installation, and configuration, use Amazon EC2.

    AWS Global Infrastructure

    • The AWS global infrastructure offers high availability and fault tolerance through multiple AWS Regions within various Availability Zones, which are located in areas with low flood risk and are interconnected with low-latency networks and redundant power supplies.

    Security Threats

    • Amazon GuardDuty is a threat detection service that continuously monitors AWS accounts and workloads for malicious activity and delivers detailed security findings for visibility and remediation.

    Support

    • An AWS Enterprise Support plan includes designated support from an AWS technical account manager (TAM).

    Encryption

    • DynamoDB encryption at rest provides enhanced security by encrypting all user data stored in Amazon DynamoDB using encryption keys stored in AWS Key Management Service (AWS KMS).

    Cost Allocation

    • Create cost allocation tags to track AWS costs on a detailed level and apply tags that represent business categories to organize costs across multiple services.

    Reliability

    • Following the reliability pillar of the AWS Well-Architected Framework achieves the design principle of testing recovery procedures.

    Database

    • Amazon DynamoDB is a high-performance NoSQL database that can be used for mobile apps.

    Deployment

    • Amazon Lightsail can be used to quickly deploy a small website and database from on-premises infrastructure to the AWS Cloud.

    Cost Management

    • To monitor AWS Cloud costs incurred by each application, set up budgets in Cost Explorer.

    Responsibility Model

    • According to the AWS shared responsibility model, the customer is responsible for maintaining the guest operating system on Amazon EC2 instances.

    Network ACLs

    • Network ACLs are stateless, and they evaluate all rules before allowing traffic, processing rules in order, starting with the lowest numbered rule.

    AWS Services

    • Amazon RDS provides cross-region read replicas, which help create globally redundant databases.
    • AWS CloudTrail monitors AWS accounts for security threats.
    • Amazon S3 is a durable storage option for retaining database backups for immediate retrieval.
    • Amazon DocumentDB (with MongoDB compatibility) is a high-performance NoSQL database that can be used for mobile apps.

    Microservices

    • Amazon Simple Notification Service (Amazon SNS) helps developers use loose coupling and reliable messaging between microservices.### Cost Allocation
    • Use tags to organize resources and track AWS costs on a detailed level
    • Apply tags that represent business categories (e.g., cost centers, application names, or owners) to organize costs across multiple services

    AWS Well-Architected Framework

    • The reliability pillar is achieved by testing recovery procedures
    • This design principle ensures reliability in the system

    AWS Services

    • Amazon DynamoDB is a non-relational database that can be quickly deployed without managing underlying hardware or database software
    • Amazon RDS is a service where AWS is responsible for installing the database engine
    • Amazon Lightsail is a service that supports quick migration of small websites and databases from on-premises infrastructure to the AWS Cloud with limited operational knowledge
    • AWS App Mesh is a service that publishes and manages web services that provide REST APIs

    AWS Shared Responsibility Model

    • Customers are responsible for maintaining the guest operating system on Amazon EC2 instances
    • AWS is responsible for maintaining the infrastructure needed to run AWS Lambda, updating the operating system of Amazon DynamoDB instances, and maintaining Amazon S3 infrastructure
    • The customer's responsibility also includes managing, patching, and configuring their resources, as well as maintaining least privilege access to the root user account

    AWS Cost Management

    • Use cost allocation tags to track AWS costs on a detailed level
    • Set budgets in Cost Explorer to monitor and manage AWS Cloud costs

    Network ACLs

    • Network ACLs are stateless, which means that responses to allowed inbound traffic are subject to the rules for outbound traffic (and vice versa)
    • Rules are evaluated starting with the lowest numbered rule when deciding whether to allow traffic
