Automated RDS Snapshot Management for Improved Data Security

2024-07-17T06:42:57+00:00

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 ensures that shareable snapshots are created every day without manual intervention, enhancing the reliability and accessibility of database backups. The Automated Daily RDS Export has several [...]

Solving HTTP 500 Errors by Increasing File Descriptor Limits

2024-07-08T08:56:55+00:00

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 to manage more connections at once. This enhances server reliability and efficiency, particularly during high traffic, leading to fewer errors and quicker responses. Additionally, it reduces [...]
