Foojay Podcast #84: Developing Performant, Cost Efficient, and Eco-friendly Code

Cloud bills keep growing and so does the energy footprint of the software we run. Tuning code often has a bigger impact than chasing a cheaper cloud contract. In this conversation we look at concrete techniques Java developers can apply today to ship faster, cheaper, and greener applications. I host Daniel Witkowski, Ko Turk, Ronald Dehuysser, and Jan Ouwens for Foojay Podcast #84.

What we talked about

• Performance tuning and cloud cost optimization with Daniel Witkowski
• Sustainable engineering and the Kepler monitoring tool with Ko Turk
• Carbon-aware job processing using JobRunr with Ronald Dehuysser
• Reducing application costs and CO2 emissions with Jan Ouwens
• Why optimizing code can outweigh a 30% cloud discount by a factor of a thousand
• Measuring energy consumption of running Java workloads
• Scheduling work to match cleaner electricity windows

Why it matters

Most teams treat cost and sustainability as separate problems. The guests show how the same engineering choices solve both. Smaller heaps, fewer wasted cycles, and smarter scheduling cut the invoice and the emissions at once.
