Industry-Specific Architectures

Industry-Specific Architectures

Architecture Breakdown by Industry

🏢 Banking & FinTech

  • Core Focus: Security, compliance, and zero-trust architecture.

  • PCI-DSS & Tokenization: Sensitive cardholder data (PAN) is isolated in a separate, highly secure environment. Tokenization replaces actual card data with a unique identifier (token).

  • Key Tech Stack: AWS KMS (with custom key rotation), AWS CloudTrail (immutable logging), Amazon Macie (PII discovery), and HSMs (Hardware Security Modules) for cryptographic operations.

🏥 Healthcare

  • Core Focus: Data privacy, auditability, and high availability.

  • HIPAA Workloads: Requires signing a Business Associate Addendum (BAA) with AWS. All Protected Health Information (PHI) must be encrypted both at rest (using AES-256) and in transit (TLS 1.2/1.3).

  • Key Tech Stack: Amazon HealthLake (for healthcare data analytics), AWS Nitro System (for enhanced isolation), Amazon Aurora (with encryption enabled), and AWS IAM for strict least-privilege access.

🎬 Media & Streaming

  • Core Focus: Massive throughput, ultra-low latency, and global reach.

  • Low Latency & CDN: Video origination (e.g., AWS Elemental) feeds into a Content Delivery Network (CDN) like Amazon CloudFront to cache video segments close to the end-users, drastically reducing buffering.

  • Key Tech Stack: Amazon CloudFront, AWS Elemental MediaLive/MediaPackage, and Amazon S3 (for video-on-demand storage).

🛒 E-commerce

  • Core Focus: Handling massive traffic spikes (e.g., Black Friday) and preventing database bottlenecks.

  • Scalable Checkout & Caching: Offloading static content and frequent database queries to caching layers. Checkout flows often use asynchronous, event-driven architectures to handle sudden spikes without crashing the payment gateway.

  • Key Tech Stack: Amazon ElastiCache (Redis/Memcached), AWS Lambda (serverless checkout logic), Amazon DynamoDB (for single-digit millisecond scale), and Amazon SQS (to queue orders safely).

🌐 IoT (Internet of Things)

  • Core Focus: Edge computing, device state management, and lightweight messaging.

  • IoT Core & Greengrass: AWS IoT Core manages millions of device connections and message routing via MQTT. AWS IoT Greengrass extends cloud capabilities to local devices, allowing them to act locally on the data they generate (edge computing) while still using the cloud for management.

  • Key Tech Stack: AWS IoT Core, AWS IoT Greengrass, AWS Lambda (running at the edge), and Amazon Timestream (for time-series IoT data telemetry).
