Jakarta Tech Talk: Thriving in the cloud, going beyond the 12 factors

Enabling applications to really thrive (and not just survive) in cloud environments can be challenging. The original 12 factor app methodology helped to lay out some of the key characteristics needed for cloud-native applications... but... as our cloud infrastructure and tooling has progressed, so too have these factors.
In this session we'll dive into the extended and updated 15 factors needed to build cloud native applications that are able to thrive in this environment, and we'll take a look at open source technologies and tools that can help us achieve this.

48. Summary @gracejansen27
49. Summary: • Twelve-factor applications = great start • But… to thrive in the cloud, we need to look beyond the 12 factors • No excuses! • Lots of open-source tools and technologies available to help • Action: Evaluate your own applications against these 15 factors and consider what you could do to enable them to truly thrive in the cloud @gracejansen27
