There are a couple points that resonate with me. I strongly believe there is a need to provide transparency and accountability to cloud engineers. How many cloud enginners know the…

It looks interesting. Is the Basti EC2 instance deployed in a private subnet? Do you have a high-level diagram?

I am working on eliminating waste in cloud resources. Cloud providers made too easy to start resources. But unless there is a stringent upfront process (that usually defeats the pu…

I am working on a cloud governance and remediation solution. Our first product was a CO2 monitor for your AWS infrastructure https://www.li10.com/ The next logical step is to provi…

yes, but it will give you a misleading number (close to 0 for any workload you run in US or EU). So it is useless.

I totally agree with you! There are so many layers we could optimize, with various level of difficulty and return in term of cost and co2 reduction. Legacy tech stack are especiall…

Shameless plug: we built www.li10.com to help companies using AWS cloud measuring and reducing their cloud carbon footprint. To measure it, we use your detailed billing data and lo…

Hi there! I'm Matt. Leader in cloud technologies, with a 17-year track record in both the US and EU. As a Senior Director of Cloud Solution Architecture at NTT DATA, I lead the dev…

Most cloud providers already claim being carbon neutral for EU and US regions. Unfortunately, there is a lot of waste there too, so there goes the little bit of green energy we hav…

What you are saying makes sense. If you are running other valuable apps, then it isn't a waste. I am curious though, how did you come to 1.75kg per user? I calculated 20.9kg / user…

Turning a service on/off makes a lot of sense for this kind of application. I sincerely didn't post my comment to shame anymore. Need for computing is growing fast and it is actual…

An idle server still consumes energy. Energy consumption increases with CPU load, RAM consumes the same regardless of the usage. When Google manages your pictures, they don't have …

Where did you get the carbon you exhale? Food. If you go by that logic, you might as well stop eating. The CO2 we exhale does not contribute to climate change because it comes from…

I used an AWS instance with similar specs as reference. What kind of low power servers are you referring too?

Yes, I assumed 1 user per server. If a family shares the server, then you can divide by the number of family members. The link I shared has the details of the calculation. The calc…

The recommended spec is 4 cores and 6GB. Running this 24/7 for a year in US where the carbon intensity is about 400 gCO₂eq/kWh would produce about 150kg of CO2 per user per year. I…

Your answer is spot on. This makes me think of Yoichi Kaya's formula: https://en.wikipedia.org/wiki/Kaya_identity It shows illustrates the dependency between GDP, population, energ…

I agree both Hertz and Accenture share some responsibility here. I didn't mean to blame it all on Hertz. "They might have been better off building a team internally". For a busines…

Here is my summary of the mistakes Hertz made: - hired the vendor based on a cool demo & vendor size - did not have a Hertz employee as Product Owner - tried to go big fast instead…

What was the best finding in your experience?

The best way I know to find new routes in my city is to join a local strava club and see where others are running. If I travel, I rely on the Segment Explorer but I agree it is not…
