🚀 Improving Security and Reducing Latency in AWS ECS-Lambda Integrations 🌐 In modern cloud applications, balancing performance and security is a critical challenge. Recently, I refactored infrastructure for my Formula 1 app running on ECS to achieve both goals by enhancing how it communicates with Lambda. Here’s what I implemented: 1️⃣ Lambda Functions in the Same VPC as ECS • By placing Lambda functions within the same VPC as my ECS tasks, and using tightly controlled security groups, I significantly improved the app’s security posture. • This eliminated the need for Lambda function URLs, and having to traverse the public internet. 2️⃣ VPC Endpoints for API Gateway • Since my app required URL-based endpoints, I leveraged VPC endpoints to enable ECS to securely connect to Lambda through a private API Gateway via AWS’s internal network. 3️⃣ VPC Endpoints for DynamoDB • My Lambda functions query DynamoDB tables, so I added another VPC endpoint to connect to DynamoDB internally. This avoided the need for traffic to flow through a NAT gateway, further reducing latency and costs. 🌟 Results: • Improved Security: Eliminated exposure to the public internet for internal Lambda and DynamoDB interactions. • Reduced Latency: Optimized the app’s performance by routing all communications through AWS’s private network. This setup has proven to be a game-changer for both security and performance.

Great post series about DDD and JPA I have really enjoyed reading these posts: https://lnkd.in/dNE__8aC I am an strong follower of DDD. However, when it comes to implement persistence, there is always a mismatch. And you must evaluate some trade-offs. Mostly when you are using a RDBMS. It doesn't matter the language, the framework or the ORM framework. This series of posts offers valuable thoughts and suggestions how to address this mismatch when using JPA.

🚀 Exploring Prometheus: Unveiling a Powerful Monitoring Toolkit 🌟 Prometheus, an open-source monitoring and alerting toolkit fostered under the CNCF umbrella, boasts a robust time series database. This design ensures optimal performance in storing and querying metric data, offering real-time insights into system health and performance. Utilizing a pull-based approach, Prometheus actively collects metrics from application endpoints and servers at regular intervals. This methodology enables dynamic discovery of targets through mechanisms like K8s service discovery, empowering users with comprehensive monitoring capabilities. Dive deeper into the world of Prometheus and discover how this toolkit revolutionizes monitoring in the tech sphere: [Link to the full article](https://lnkd.in/e4KqcP7n) #Prometheus #OpenSource #Monitoring #CNCF #Tech #Innovation

InvalidImageName: In Kubernetes, if you encounter the status InvalidImageName, it usually indicates that there is an issue with the container image specified in your Pod or Deployment manifest. This status is set by the Kubelet when it attempts to pull an image but encounters problems due to an invalid image name format.
