Cloud meets Sustainability | hybrid

This is a joint meetup of Green Software Development Manifesto and Cloud Native Night Munich.

One of the many benefits attributed to the cloud is sustainability. But how can we measure the emissions of applications running in the cloud? Which approaches help us to limit these emissions to the bare minimum? In our joint Cloud Native Night and Green Software Development meetup, we address these questions at cloud infrastructure provider level and (k8s) cluster level.

This hybrid meetup will take place on Nov 9th, 2023 at the office of QAware GmbH at Aschauer Str. 30, Munich and remote.

Please register at Zoom Events if you'd like to attend remotely.

Measuring Emissions of Cloud Infrastructure in AWS, GCP and Azure

Dennis Breitling (IT Consultant, codecentric)

People everywhere are raving about the cloud: unlimited scaling and countless features are already available "out of the box". The issue of sustainability is rarely mentioned. Today, however, data centers already consume as much energy as small towns and the demand for energy continues to rise. This raises the question about the emissions caused by our cloud architectures. In this talk we will learn about the tools provided by the major cloud providers AWS, GCP and Azure to measure the emissions caused by our usage of their platforms.

Blue turns green! Approaches and technologies for sustainable K8s clusters

Mario-Leander Reimer

The cloud already has a larger CO2 footprint than the worldwide aviation industry. With increasing digitalization and cloudification this trend will continue if we don’t do anything about it. Many Kubernetes installations are greatly oversized in terms of the resources actually required and thus contribute unnecessarily to global warming. What is the energy balance of your cluster and its workloads?

In this session we will discuss approaches and technologies that help to make K8s clusters green(er). First of all, transparency is needed: what is the energy balance of the cluster and its workloads? Only then we can start to optimize for better energy efficiency through elasticity and reducing “waste”. And it’s not that difficult, so let’s get started!
