    Study Notes

    Application Integration Services

    • Amazon EventBridge: An event bus service routing events between AWS services and custom applications. Use cases include monitoring application events, triggering workflows, and automating operational responses. Events are routed to multiple targets; delivery is typically "at least once" (though may be "exactly once" depending on configuration). Order of processing isn't guaranteed. Integrates with AWS services and SaaS.

    • Amazon SNS (Simple Notification Service): A managed service sending notifications (email, SMS, push). Use cases include alert systems, sending marketing messages, or notifying users of system updates. Delivers messages to subscribers; delivery is "at least once" with no order guarantee. Supports various delivery protocols.

    • Amazon SQS (Simple Queue Service): A message queuing service decoupling and scaling microservices, distributed systems, or apps. Facilitates asynchronous communication between application components. Messages are processed by consumers. Delivery is "at least once" for standard queues; "exactly once" for FIFO queues. FIFO (First-In, First-Out) supports strict ordering. Integrates with services like Lambda and EC2.

    • EventBridge vs. SNS vs. SQS: Key differences include purpose (Event-driven, publish/subscribe, message queues), message handling (routing, delivery, processing), delivery guarantee (exactly/at least once), and order of processing.

    • When to use each: Choose EventBridge for workflows triggered by events, SNS for broadcasted notifications, SQS for decoupled, scalable components, and potentially a combination of SNS+SQS for fan-out notifications with reliable queuing.

    • Integration Example: A photo-processing application uses EventBridge to detect new S3 uploads (triggering a workflow), SNS to email users about processing, and SQS to buffer tasks for backend processing without overload.

    Business Application Services

    • Amazon Connect: A cloud-based contact center for managing inbound/outbound customer calls and chats.

    • Amazon SES (Simple Email Service): A service for sending transactional and bulk emails (e.g., marketing campaigns, invoices, application-generated emails).

    Customer Engagement Services

    • AWS Activate for Startups: Providing tools, credits, and guidance to startups on AWS.

    • AWS IQ: Connecting users with AWS Certified Experts for guidance on AWS projects/issues.

    • AWS Managed Services (AMS): Providing operational support for AWS infrastructure (managing day-to-day operations, automating backups, patching,etc.).

    • AWS Support: Technical support plans (Basic, Developer, Business, Enterprise) to address questions, troubleshoot issues, and resolve operational challenges.

    Developer Tool Services

    • AWS services for developers are comprehensive and automate aspects of the development lifecycle, covering configuration management, IDEs, command-line interfaces, artifact repositories, continuous integration/continuous delivery (CI/CD), version control, and distributed application tracing. They streamline application building, deployment, and troubleshooting.

    End-User Computing Services

    • Amazon AppStream 2.0: Streams desktop applications to a web browser, enabling remote access without local installation.

    • Amazon WorkSpaces: Fully managed virtual desktops for secure remote work environments (for workers/contractors).

    • Amazon WorkSpaces Web: Provides web-based access to cloud applications for securing access to internal applications.

    Frontend Web and Mobile Services

    • AWS Amplify: Building, deploying, and hosting full-stack web and mobile applications.

    • AWS AppSync: A managed GraphQL service for real-time data syncing, suited for applications requiring real-time collaboration (like messaging or dashboards).

    IoT Services

    • AWS IoT Core: Connects IoT devices to the cloud for data exchange, supporting real-time data processing and IoT device management.

    • AWS IoT Greengrass: Runs IoT applications on edge devices, enabling offline operation and local data processing on IoT devices.

    Real-World Scenarios

    • Event-Driven Applications: Use EventBridge for triggering workflows based on events (e.g., new S3 file uploads); use SQS to manage tasks for processing.

    • Customer Engagement: Use Amazon Connect for customer support and Amazon SES for transactional emails (receipts, order confirmations).

    • Developer Workflow: Use AWS CodePipeline for automated code deployment and AWS X-Ray for troubleshooting performance issues in microservices

    • IoT Device Management: Use AWS IoT Core for secure sensor connectivity and AWS IoT Greengrass for local data processing.
