AWS Monthly (April ’25): Cooling the AI Heat
In April, AWS gave us a peek behind the curtain of their data center engineering. To handle the thermal output of the latest AI clusters, they unveiled Direct-to-Chip Liquid Cooling. This is more than just a hardware curiosity. From a performance standpoint, liquid cooling allows for 3x higher compute density per rack. It ensures that…
AWS Monthly (Mar ’25): The Proximity Power Play
March was about the physical foundation of the cloud. AWS announced a $100 billion global investment, and for us, that translated into over 20 new Local Zones going live. Technically, this brings “Single-Digit Millisecond Latency” to almost every major tech hub. If you are building AR/VR backends, industrial IoT, or sub-millisecond telemetry systems, the “distance…

AWS Monthly (Jan ’25): Shattering the 6MB Ceiling
We kicked off 2025 by addressing one of the oldest “bottleneck” complaints in the serverless community. For years, the 6MB payload limit for synchronous Lambda calls forced us into complex workarounds involving S3 pre-signed URLs or asynchronous patterns for anything remotely data-heavy. In January, AWS officially bumped Lambda response streaming capabilities to 200 MB. Technically,…
Setting up DKIM for Google Workspace (Gmail) using Terraform and AWS Route 53
DKIM (DomainKeys Identified Mail) is a critical email authentication technique that helps prevent email spoofing. By using DKIM, you digitally sign your email headers with a private key, and the recipient verifies this signature using your public key, which is stored in the DNS records of your domain. Google Workspace (formerly G Suite) leverages DKIM…
Automate AWS Site-to-Site VPN Monitoring

For many businesses, AWS Site-to-Site VPN serves as the bridge that connects their data centers to AWS, enabling private, encrypted communication channels. But what happens when your VPN tunnel goes down? Without proper visibility or a notification system…
Monitoring EC2 Disk Space with a Simple Bash Script and Slack Alerts
Introduction In the cloud infrastructure landscape, monitoring the health and resources of EC2 instances is essential. One common challenge for system administrators is ensuring that disk space doesn’t run out, which can lead to performance degradation or service outages. While AWS provides robust monitoring tools like CloudWatch, they can incur additional costs and complexity, especially…
Accessing AWS Services in Private Subnets Without 0.0.0.0/0
When working with AWS (Amazon Web Services), securing your infrastructure is paramount. One of the most common security practices is to restrict access to your private subnets by avoiding the use of 0.0.0.0/0, which represents all IP addresses globally. While this enhances security, it can also present challenges when your applications and services need to…
