Chip Zoller makes the argument in favor of running Kubernetes in/on virtual machines. Christian Posta talks about how microservices are not the only approach to software design, and then walks through the recent shift in Istio—the open source service mesh—from a microservices-based architecture to a more monolithic approach.

As opposed to just encrypting data at the transport level (although Acra does that between components of its architecture) or just encrypting data at the storage level (using an encrypted file system or similar), Acra targets encrypting data at the table/row/column level within a database. Acra is open source and available via GitHub.
