Introduction to Amazon VPC Amazon Virtual Private Cloud (VPC) is a logically isolated section of the AWS cloud where you can launch AWS resources in a virtual network that you define. It gives you full control over your network setup, including: IP address ranges Subnets Route tables Network gateways Security settings  Key Building Blocks of a Secure VPC Architecture 1. CIDR Block Planning Choose an appropriate CIDR range (e.g., 10.0.0.0/16 ) to avoid overlap with on-prem or other VPCs. Plan for subnet segmentation by reserving smaller CIDR blocks. 2. Subnets Public Subnets : For internet-facing services like ALB, NAT Gateway. Private Subnets : For databases, internal services. Isolated Subnets : No route to the internet—used for critical data. 3. Internet Gateway (IGW) Needed for outbound traffic from public subnets to the internet. 4. NAT Gateway Allows outbound internet access for private subnets while blocking inbound connections. Deploy in a highly available setup across mult...

Introduction In today’s cloud-native ecosystem, event-driven architecture (EDA) is critical in building scalable, decoupled, and highly responsive systems. AWS Lambda and Amazon S3 are among the most powerful tools for implementing EDA on AWS. This guide walks you through how to build an event-driven architecture using S3 as the event source and Lambda as the event handler. What is Event-Driven Architecture? Event-driven architecture is a design pattern in which services communicate through events. Events are state changes or updates triggered by a user action or system operation. Instead of polling for changes, services react to events in real time. Benefits of EDA include: Loose coupling of components Real-time data processing Improved scalability and maintainability Efficient resource utilization Key AWS Components for EDA 1. Amazon S3 (Simple Storage Service) A scalable object storage service that can emit events such as PUT , DELETE , or COPY actions on objects. 2. AWS Lambda ...
