The IT industry has a large carbon footprint, and IT professionals have a responsibility to tackle climate change. Going to the cloud and using serverless are effective ways to reduce resource usage and carbon footprint. However, these routes are not always feasible, and making applications more efficient is another approach to reducing resource usage.

• Observability, the ability to perceive the state and behavior of IT systems at scale, can help make applications more efficient.
• Observability helps identify the root cause of high resource usage, allowing IT professionals to take action to improve efficiency and reduce carbon footprint.
• There is a cost to applying observability, but the benefits for solving problems, making better decisions, and tackling climate change far outweigh those costs.
• Gartner has named Applied Observability as one of the 2023 Technology Trends.
