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.

- 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 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.

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.
