Azure Storage redundancy functions not merely as a protective veil but as a sophisticated framework interwoven with engineering intelligence, designed to defend against disruption and… Read More »

Quick SFTP Server Setup on Ubuntu EC2 for Secure File Transfers

In an era where cloud computing dominates modern infrastructure, securing data during transfer is paramount. The Secure File Transfer Protocol, commonly abbreviated as SFTP, is a robust method designed to enable encrypted file exchanges between clients and servers. Unlike traditional FTP, which transfers data in plaintext, SFTP encapsulates the communication within the SSH protocol, providing… Read More »

Cut AWS Lambda Costs Effectively Using Event Filters

AWS Lambda is a serverless computing service that allows developers to run code without provisioning or managing servers. You pay only for the compute time consumed by your function invocations. While Lambda eliminates the need for infrastructure management, costs can rise quickly with frequent or unnecessary function triggers. Understanding how Lambda charges are calculated is… Read More »

Optimize AWS Lambda Costs Using Event Filtering Techniques

AWS Lambda has transformed how serverless applications are built by abstracting infrastructure concerns and enabling event-driven architectures. However, as serverless adoption grows, many developers face escalating costs from excessive Lambda function invocations triggered by unfiltered events. Each Lambda invocation incurs a charge, regardless of whether the event is pertinent or merely noise. This financial drain… Read More »
