Automated RDS Snapshot Management for Improved Data Security
The Automated Daily RDS Export ensures that daily snapshots of Amazon RDS instances are created and made shareable. While RDS takes daily snapshots automatically, these are not shareable by default. To address this, we copy the snapshots and share the copies with a designated backup account. This process uses AWS Lambda Functions and Amazon EventBridge to automate the task. EventBridge triggers the Lambda function daily, which handles copying and sharing the snapshots. This automation [...]
Solving HTTP 500 Errors by Increasing File Descriptor Limits
When it comes to web hosting and server management, facing HTTP 500 errors can be a challenging obstacle. Such errors frequently arise from file descriptor limits, which restrict the server's capacity to manage incoming requests efficiently. However, by understanding how to expand these limits, you can reduce the occurrence of HTTP 500 errors and guarantee more seamless operations for your web applications. Raising file descriptor limits helps fix HTTP 500 errors by enabling servers [...]
Exploring C++ with AWS Lambda Custom Runtime
AWS Lambda is a great service for running code without worrying about server management.

This is where real-time Slack notifications for AWS budget alerts come into play. By integrating AWS budget alerts with Slack, these notifications are sent [...]
Understanding and Managing AWS Lambda Recursive Loop Invocations
Introduction AWS Lambda is a serverless computing service that allows developers to run code without provisioning or managing servers. It automatically scales applications by running code in response to events and only charges for the compute time used. This makes AWS Lambda an ideal choice for building scalable and cost-effective applications. However, one challenge that developers might encounter is recursive loop invocations. This occurs when a Lambda function inadvertently triggers itself, leading to a [...]
