The old constraint when it came to technology was hardware -- how many CPUs can I get my hands on. Today, spinning up compute can be done from any smartphone with an AWS account or something similar.

What are the emerging platforms, ecosystems, and tools that help developers succeed at what is increasingly the most important job in any company – writing and running software.
