    Study Notes

    AWS Identity and Access Management (IAM) Overview

    • IAM allows secure control of individual and group access to AWS resources.
    • It provides centralized account control and shared access management.
    • By default, new users have no access; permissions must be explicitly granted.

    IAM Users

    • IAM users are entities that represent individuals or services accessing AWS accounts.
    • Each user has three main components: security credentials, permissions, and user names.
    • It's best practice to create individual accounts for users rather than sharing credentials.
    • Up to 5,000 users can be created per AWS account.

    Permissions and Policies

    • Granular permissions can be applied to IAM users.
    • IAM users can be assigned access keys, passwords, and configured with multi-factor authentication (MFA).
    • Permissions are defined using policies written in JSON, and all permissions are implicitly denied by default.

    Multi-Factor Authentication (MFA)

    • MFA can be enabled for the AWS account and individual users, enhancing security.
    • MFA involves a device generating random, single-use authentication codes.

    Roles and Groups

    • Roles define a set of permissions and can be assumed by trusted entities.
    • Groups are collections of users with attached policies, but cannot be used as principals in IAM policies.
    • Roles can grant temporary security credentials without permanent credentials.

    Policy Types

    • Types of policies include managed policies (AWS-defined) and inline policies (user-defined for specific users/groups).
    • AWS managed policies cannot be modified, while customer-managed policies can be attached to multiple roles or users.

    IAM Policy Evaluation Logic

    • All requests are implicitly denied unless explicitly allowed.
    • An explicit deny in any policy overrides any allow.
    • The most restrictive policy takes precedence if multiple policies apply.

    AWS Security Token Service (STS)

    • STS provides temporary, limited-privilege credentials for IAM users and federated users.
    • Credentials can be requested globally, and help facilitate cross-account access.

    Cross-Account Access

    • Allows users from one AWS account to access resources in another account.
    • Requires attached resource-based policies or assuming roles in the target account.

    IAM Best Practices

    • Do not use the root account for administrative tasks.
    • Use MFA for all users, especially for privileged accounts.
    • Implement the principle of least privilege when assigning permissions.
    • Regularly change access keys and passwords.

    AWS Application Integration Services

    • A suite of services designed for decoupled communication between application components.
    • Supports microservices, distributed systems, and serverless architectures.
    • Enables connectivity without custom code, ensuring resilience against failures in individual components.

    Amazon Simple Notification Service (SNS)

    • Managed messaging service for application-to-application (A2A) and application-to-person (A2P) communication.
    • Utilizes a pub/sub model for high throughput, push-based messaging.
    • Supports notifications to multiple platforms, including mobile devices, SMS, email, and any HTTP endpoint.
    • Triggers AWS Lambda functions to process messages automatically.
    • Messages can be stored redundantly across multiple availability zones, ensuring durability.
    • Allows grouping of multiple recipients via Topics, enabling dynamic subscription to notifications.

    Amazon Simple Queue Service (SQS)

    • Provides a distributed queue system for reliable message queuing between application components.
    • Acts as a buffer to help manage differences in processing speed between producers and consumers, promoting decoupling.
    • Messages can be stored for 1 minute to 14 days, with a default retention of 4 days.
    • Guarantees at least once delivery of messages, with two queue types: Standard and FIFO.

    Standard Queues

    • Default type, supports nearly unlimited transactions per second.
    • Guarantees at least once delivery but may deliver duplicates out of order.
    • Best-effort ordering generalizes message delivery in the order sent.

    FIFO Queues

    • Ensures strictly ordered, exactly-once processing of messages.
    • Supports message groups for containing multiple ordered groups within a single queue.
    • Limited to 300 transactions per second, preventing duplicate messages with Message Group ID and Message Deduplication ID requirements.

    SQS Visibility Timeout

    • Defines the period a message remains invisible after being read to avoid multiple processing.
    • Default is 30 seconds, adjustable to a maximum of 12 hours.

    SQS Polling

    • Long polling retrieves messages only when available, improving efficiency compared to short polling, which returns immediately.
    • Long polling can be activated at the queue or API level.

    Dead-Letter Queues

    • Isolates and manages messages that fail processing for further analysis.
    • Messages move to this queue after exceeding a predefined maxReceiveCount.

    Delay Queues

    • Allows postponing message deliveries for up to 900 seconds (15 minutes).
    • Changes affect only new messages, not those already in the queue.

    Amazon Simple Workflow Service (SWF)

    • Coordinates distributed application components through workflows with parallel or sequential steps.
    • Ideal for longer tasks that require state tracking and retry capabilities.
    • Integrates with a task-oriented API, providing a domain for application resources and managing tasks' state.

    Amazon MQ

    • Managed message broker service supporting ActiveMQ, facilitating migration without code rewrites.
    • Automatically provisions infrastructure for high availability and redundancy across Availability Zones.
    • Supports standard messaging APIs such as JMS, NMS, MQTT, and WebSockets.
    • Ensures security through SSL connections, VPC isolation, and message encryption.

    AWS Step Functions

    • Orchestrates components of distributed applications via visual workflows and state machines.
    • Allows the definition of tasks with sequential, parallel, and branching steps.
    • Provides a visual interface for execution status and detailed logs for monitoring each step.
