Navigating the container ecosystem can be confusing. Deciding where to dip your toes is challenging for those stepping into container and microservices waters. Even those who have already ventured knee-deep still wade through many questions as they progress in their cloud native journey. To help them guide them through the ecosystem, the Cloud Native Computing Foundation (CNCF) recently launched a Cloud Native Ambassadors program at its inaugural CloudNativeDay in Toronto.

Recognized for their expertise, Cloud Native Ambassadors are individuals who belong to a CNCF member organization and are selected based on their passion for cloud native technology and willingness to help others learn. Most ambassadors also organize or are involved in community meetups oriented toward technologies and projects governed by the CNCF. Forty-one meetups worldwide have joined the program to date (disclaimer: I’m a CNCF Ambassador  and an organizer of the Microservices and Containers Austin meetup in Austin, TX.). Continue reading »

Security has and continues to be an impediment to container adoption. Whether containers are less or more secure than their virtual machine counterparts is a topic of continued debate.

Like any debate, there are merits to arguments on both sides with a bit of FUD interlaced. Many efforts have been undertaken within the container ecosystem to educate adopters and improve their comprehension of available tooling and security postures within platforms and offerings—be that in the form of static analysis (image scanning), runtime vulnerability detection, provenance (image signing), fine-grained authorization, cryptographic verification, etc.
