Check it out first. “Policy as code” is one of the more recent “as-code” buzzwords to enter the discourse since “infrastructure-as-code” paved the way for the […]
In general, AWS Lambda functions are triggered by some sort of event. Most common use cases are an event from EventBridge, SQS, or an event created by a call to API Gateway in case you have a REST/HTTP API based on an AWS Lambda function. However, the other day I was looking for an option […]
Hosting a website on AWS using Cloudfront, S3 and Route53 is a popular solution for Amazon web hosting. It typically costs $3 a month outside the generous free tier and $0.50 within the free tier. Terraform can automate the deployment of this finicky architecture, making it much easier to deploy, manage and automatically upload website […]

Cassandra is a highly scalable database with an architecture that makes it well suited for multi-region workloads. As companies are standardizing on Kubernetes, they often want their clusters to span across multiple zones within a single region. However, multi-region Kubernetes clusters have serious technical challenges to overcome to be used in production. The challenge of […]
IAM (Identity and Access Management) is one of the most important yet complicated layers of cloud security. To add insult to injury, each major cloud provider (AWS, Azure, GCP) handles IAM differently, requiring cloud security professionals to learn different capabilities, restrictions, and terminology when managing IAM in a given environment. With infrastructure cloudification growing in […]
Note: This is the second of a five-part series covering Kubernetes resource management and optimization. In this article, we explain Kubernetes requests and limits. You can check out part one explaining Kubernetes resource types. Kubernetes provides a shared pool of resources that it allocates based on how we configure our containerized applications. The allocation process occurs when a […]
