Four hot startups aim to keep AI data centers cool

Sun, 24 Aug 2025 09:00:00 +0000

Data centers consume up to one-third of their energy for cooling, driving demand for innovative solutions. Direct-to-chip cooling, a emerging technology, uses cold plates to target heat sources directly on CPUs/GPUs, improving efficiency and sustainability. Traditional cooling relies on large chillers and water systems, while direct-to-chip cooling attaches cold plates to processors. These plates use liquid or advanced materials to absorb heat locally, reducing reliance on centralized cooling and lowering energy use. By Heather Clancy.

Replace traditional email mailbox polling with real-time reads using Amazon SES and Lambda

Wed, 17 Nov 2021 11:55:00 +0000

Integrating emails into an automated workflow for automated processing can be challenging. Traditionally, applications have had to use the POP protocol to connect to mail servers and poll for emails to arrive in a mailbox and then process the messages inline and perform actions on the message. This can be an inefficient mechanism and prone to errors that result in the workflow missing messages. Since this method requires polling it’s not great if you need real-time processing of messages and introduces inefficiencies in the design. By Syed Ali Abbas Gardezi and Satish Natarajan.

Amazon MemoryDB for Redis – Where speed meets consistency

Tue, 16 Nov 2021 08:00:00 +0000

Modern apps are not monolithic; they’re composed of a complex graph of interconnected microservices, where the response time for one component can impact the performance of the entire system. For instance, a page load on an e-commerce website may require inputs from a dozen microservices, each of which must execute quickly to render the entire page as fast as possible so you don’t lose a customer. It’s critical that the data systems that support those microservices perform rapidly and reliably, and where speed is a primary concern, Redis has always been top performer. By Dr. Werner Vogels.
