Study Notes
AWS Global Infrastructure
- AWS infrastructure is deployed globally.
- The infrastructure is structured around AWS Regions.
- Each AWS Region comprises multiple Availability Zones (AZs)
- Data centers locate within these AZs within each region.
- This global structure minimizes latency (delay between action and response).
- Each region is isolated from others.
- Resources and data storage can be placed across multiple regions and AZs within a region.
- AZs are geographically separated within a region, mostly in low-risk flood plains.
Content Delivery Network (CDN)
- Data is distributed geographically, stored close to consumers.
- This approach accelerates content access.
AWS CloudFront
- A global CDN service.
- It determines user location and routes traffic to the nearest cached location for rapid loading.
- Content delivery depends on user location, website origin, and CDN server location.
- CloudFront integrates with other AWS services for optimal performance and security.
- CloudFront uses edge locations worldwide to cache resources for quicker user access near the location.
Security
- The AWS Well-Architected Framework includes security as a core pillar.
- It entails establishing a strong identity foundation, enabling traceability, and implementing security measures at all levels.
- Automation of security best practices and protection of data in transit and at rest are crucial components.
- Separating users from sensitive data is vital to security.
- AWS service providers provide a range of security tools.
Shared Responsibility Model
- Cloud Service Providers (CSPs) are responsible for securing the cloud infrastructure.
- Their responsibilities include the data center, data isolation, and network security within the data centers.
- Cloud consumers are responsible for securing their data and applications in the cloud.
- Their responsibilities include direct user access rights management, data backup, and restoration.
AWS Security & Compliance
- The AWS Cloud employs a shared responsibility model.
- AWS manages the cloud's security, but consumers bear responsibility for the security of their applications, data, and networks.
- AWS offers tools and features for network security, configuration management, access control, and data encryption.
- AWS environments undergo continuous audit with certifications from accreditation bodies.
Cloud Service Models
- Traditional IT: Customer manages all aspects of the infrastructure, applications, and data.
- Infrastructure as a Service (IaaS): Customers manage application, data, and runtime layers while AWS manages the infrastructure.
- Platform as a Service (PaaS): Customers manage applications and data while AWS manages the platform.
- Software as a Service (SaaS): Customers manage data while AWS manages the entire software service.
Access Management
- Authentication: Verifying user identity using credentials.
- Authorization: Determining authorized access level based on identity.
- Principle of Least Privilege: Granting only essential permissions.
AWS CloudWatch Monitoring
- Monitors the utilization and status of resources under AWS management.
- CloudWatch Agent gathers metrics at the system level for Amazon EC2 instances and on-premises servers.
- Event-based and time-based monitoring mechanisms exist.
AWS Identity and Access Management (IAM)
- Securely manages user and group access to AWS resources.
- Integrates with most AWS services.
- Supports federated identity management and granular permissions.
- Enables Multi-Factor Authentication (MFA).
- Provides identity information for assurance and compliance audits.
Data Security
- Data at rest: Secure storage for data.
- Data in transit: Secured data movement between systems.
- Mechanisms for key management, encryption, access controls, and data auditing are employed.
AWS Key Management Service (AWS KMS)
- Facilitates cryptographic key creation and management.
- Utilizes hardware security modules (HSMs) for key protection.
- Integrates with other AWS services.
- Enables customized usage policies for determining user key access.
Logging and Monitoring
- Logs capture activity and event data for specific services.
- Monitoring continuously verifies security and performance.
- AWS provides services for comprehensive visibility into issues.
CloudWatch Dashboard
- Presents data about the running AWS ecosystem.
- Leverages existing monitoring tools.
AWS CloudTrail
- Logs and monitors account activity across AWS infrastructure.
- Records API calls from most AWS services, including Console and CLI.
- Automatically uploads logs to S3.
- Tracks events across AWS services.
- Provides analysis tools and identifies issues like unauthorized access or configuration changes.
Amazon CloudWatch
- A unified monitoring and observability service for AWS resources.
- Provides system-level metrics from both AWS resources and pre-existing on-premise systems.
- Provides customization features for logs and events.
