Mastering Event-Driven Architecture: When and Why to Use It ⚡

Event-Driven Architecture (EDA) is gaining popularity for real-time processing and scalability, offering benefits like scalability and decoupled systems.
Challenges of EDA include debugging complexities and eventual consistency, despite its advantages in modern systems.
EDA consists of core components like Event Producers, Event Consumers, Event Broker, and optional Event Store for event processing.
Key event patterns in EDA include Event Notification, Event-Carried State Transfer, Event Sourcing, and Command Query Responsibility Segregation (CQRS).
Essential characteristics of events in EDA include immutability, atomicity, uniqueness, ordering, and idempotence.
Event-Driven efficiency ensures only necessary processes are triggered, optimizing resource utilization.
Implementation patterns like Event Schema Versioning, Dead Letter Queues, Saga Pattern, and Outbox Pattern enhance the effectiveness of EDA.
Anti-patterns to avoid in EDA include Event Overload, Synchronous Event Processing, Missing Event Versioning, and Tight Coupling Through Events.
Benefits of choosing EDA over traditional architectures include loose coupling, scalability, resilience, and real-time processing.
EDA aligns well with microservices, enabling independent scaling, asynchronous processing, event replay, and extensibility.

Convert GeoJSON to PMTiles with AWS Serverless Pattern

PMTiles is a Cloud-optimized format for storing and serving map tiles in a "serverless" way.
Protmaps provides examples of serving PMTiles with AWS Lambda or serverless infrastructure.
The article demonstrates creating PMTiles in a serverless manner using AWS services.
The architecture involves S3 buckets for input GeoJSON and output PMTiles, along with a Lambda function for conversion.
S3 event notifications trigger the Lambda function for GeoJSON to PMTiles conversion.
The Lambda function downloads GeoJSON, runs tippecanoe for conversion, and uploads PMTiles to S3.
The article includes CDK Stack and Lambda codes for implementing the serverless PMTiles conversion.
A Docker container image is used for the Lambda function with tippecanoe dependencies.
The article covers testing by putting GeoJSON to S3, Lambda processing, and PMTiles upload.
PMTiles Viewer is suggested for checking the contents of PMTiles.

Simple SIEM Home Lab Using Elastic Cloud

This article serves as a guide for setting up a SIEM home lab using Elastic Cloud and a Kali Linux VM, providing hands-on cybersecurity experience.
Prerequisites include virtualization software, an Elastic Cloud account, and basic Linux and virtualization knowledge.
Tasks include setting up an Elastic account, configuring a Linux VM, setting up an agent to collect logs, querying for security events, creating a dashboard, and setting up alerts.
Setting up the Elastic account involves creating a deployment, while configuring the Linux VM follows official documentation guidelines.
The agent plays a crucial role in collecting and forwarding logs from the Kali VM to Elastic Cloud for analysis and monitoring.
Querying for security events involves accessing the Elastic deployment, searching for logs, entering search queries, executing searches, and reviewing search results.
Creating a dashboard allows visualization of security events, while setting up alerts helps in detecting and responding to security threats promptly.
Configuring alerts involves defining rules based on custom queries, adding descriptions and actions, and enabling the rules for continuous monitoring.
This project enhances skills in security monitoring, incident response, and familiarity with SIEM tools, offering practical experience in security analysis.
Overall, the article provides a comprehensive overview of setting up a SIEM home lab using Elastic Cloud, enabling hands-on exploration of cybersecurity concepts.

One CloudFront distribution to rule them all

In a startup environment, consolidating services into a single CloudFront distribution can reduce costs and latency by minimizing requests.
Successful consolidation requires unique paths for APIs and S3 resources, avoiding overlaps.
Using AWS CDK simplifies setup for various AWS resources like DynamoDB tables, S3 buckets, Lambda functions, and more.
Maintaining CORS support and access control during consolidation without compromising existing caching strategies is crucial.
Configuration examples for HTTP APIs and static websites with CloudFront distributions showcase effective setup techniques.
Lessons learned include optimizing CORS protocols, handling 404 Not Found errors, and managing HTTP headers for improved performance.
Mitigation strategies involve leveraging CloudFront, optimizing caching, and using WebSocket connections for efficient communication.
Consolidating services under a single CloudFront distribution can simplify infrastructure management, reduce costs, and enhance performance.
Custom headers, error handling, and security considerations are key aspects to consider when consolidating services.
The approach of consolidating CloudFront distributions offers benefits for various applications, making it a compelling strategy to explore.
