Transferring an Amazon Route 53 Domain to Another AWS Account: Troubleshooting DNS Propagation

2024-08-28T06:02:20+00:00

I recently transferred my domain to a different AWS account. However, despite waiting for the standard 24-48-hour DNS propagation period, I noticed the changes were not propagating as expected. In this article, we’ll delve into the steps I followed, potential pitfalls, and solutions to ensure a smooth domain transfer process. DNS propagation is the process of updating and reflecting changes made to your domain's DNS records across all DNS servers worldwide. When you make changes to DNS records, for example, updating your domain's IP address or name servers, these changes need to be communicated to all DNS servers on the [...]

Understanding Security Groups and Network Access Control Lists (NACLs) in AWS

2024-08-26T09:31:42+00:00

Security within cloud environments is a critical consideration, and AWS offers robust tools to ensure that your cloud infrastructure remains secure. Two critical components in AWS for managing security are Security Groups and Network Access Control Lists (NACLs). These tools act as virtual firewalls, controlling the traffic that enters and exits your Virtual Private Cloud (VPC). While they serve similar purposes, they operate differently and are used in distinct scenarios to provide layered security. Security Groups: Instance-Level Security Security Groups in AWS are designed to control inbound and outbound traffic at the instance level. They are stateful, meaning that if [...]

Path-Based Routing with Application Load Balancer (AWS ALB): Efficiently Directing Traffic Based on URL Paths

2024-08-11T13:05:16+00:00

An Application Load Balancer enables you to set up a listener with rules that direct incoming requests to target groups based on the URL. This capability is unique to Application Load Balancers and is not offered by other load balancer types like Classic Load Balancer, Network Load Balancer, and Gateway Load Balancer. The path pattern rules only apply to the path of the URL and do not consider the URL's query parameters. Path-based routing allows you to host multiple microservices behind a single ALB, directing traffic to the appropriate service based on the requested path. Important Purposes of Path-based Routing [...]

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 [...]
