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.

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 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.

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.
