AWS Lambda Just Got Faster: What the New Network Bandwidth Increase Means for Developers
A function might need to download a large file from Amazon S3, call another service, process the response, and upload the result somewhere else. In such cases, giving the Lambda more CPU does not necessarily solve the problem if the function is spending most of its execution time waiting for data to move across the network.
Crazy prototypes in JavaScript
Managing prototypes manually feels heavy on your head because you are forced to write fragmented code across different lines, whereas classes let us group everything inside a single, clean block.
Terraform State Lock: A Common CI/CD Pipeline Challenge and How to Resolve It
Terraform uses state locking to prevent multiple operations from modifying the same state file simultaneously.
Why I should care about a Rate Limiter?
your system need a rate limiter– To prevent the DDoS attacks,– reduce costs,– error handling – it prevents DDoS attachs – distributed denial-of-service attempts.– limits unnecessary strain on computing resources, saving infrastructure spend.– it avoid overloading on our workload – ensures our happy users don’t accidentally or maliciously hog resources and ruin the experience for […]
Mistake we have to AVOID:
“Many engineer think – If my system is highly available, then I have disaster recovery.” Not necessarily. A system can be highly available and still have poor disaster recovery.
Rate Limiting in C# (Part 1): Fixed Window Algorithm Explained with Real-World Edge Cases
Rate limiting is one of the most critical components in backend systems. It protects APIs from abuse, ensures fair usage, and stabilizes systems under load.
Understanding Encapsulation and Abstraction in C#: From Syntax to System Design
When developers start learning object-oriented programming, concepts like encapsulation and abstraction often feel theoretical. But in real-world systems, these ideas are not just academic—they directly influence how maintainable, scalable, and reliable your code becomes.
