Quick Summary
In this episode of Horizon 2030 for Banking from Red Hat, Dario Molinari, Senior Solutions Architect, discusses Red Hat's commitment to sustainability, the efficiency of containers, and why he believes financial institutions still take sustainability seriously.
How Does He Connect Open Source to Sustainability?
Dario describes the open source ecosystem as an ecosystem of efficiency: components are built on the principle of not building a giant system where a small one will do. A container, he says, is a lot leaner than a physical machine and a lot leaner than a virtual machine. Over the last decade, the financial institutions he works with have refactored applications to containers, which he says has produced a decrease to the tune of hundreds of millions of dollars, reflected in smaller infrastructure, lower resource consumption and better processes for maintaining a leaner estate.
What About Metering and Reporting?
- He notes additional requirements for metering, reporting and green IT.
- Red Hat is active in the green IT community.
- Red Hat is instrumenting its products and customers' environments with energy-consumption metrics, and adding monitoring, metering and telemetry to application development cycles.
Is Sustainability Still a Priority?
Dario says he has heard from the banks he works with that the industry is past the greenwashing stage. Although the geopolitical situation appears to have moved away from sustainability as an objective, he finds financial institutions still take it seriously because of their duty to investors and because many of their products are centred on it. He argues that organisations without sustainability among their top three criteria will suffer, if only from an efficiency standpoint, as energy and resources become scarce.
