Bridget Kromhout discusses four things to consider about containers: 1) They aren't new technology but are different than previous implementations, 2) They aren't just for development and can be used for production environments, 3) They require rethinking architecture to take advantage of their benefits, and 4) Containers cannot be ignored as their use continues to grow.
