Cost savings, flexibility, and increased mobility aren't the only cloud computing benefits getting the attention of CIOs these days. The energy and emissions savings associated with cloud computing is also a factor for companies that realize the inevitable business implications of climate change. A recent study found that cloud computing uses 90% less energy than traditional on-premises applications. And if all enterprise software moved to the cloud, the environmental benefits would be staggering. Join us in a deep dive on this topic with a customer, a cloud expert, an analyst, and a cloud app developer. You'll leave with a greater understanding of how and why cloud computing is an important part of your sustainability strategy.
