TL;DR - Yes! Bastions are still the recommended solution to manage secure remote access to cloud infrastructures. There is a growing discussion among network engineers, DevOps teams, and security professionals about the security benefits of bastions. Many assume that they are the “old way” of network access and have little relevance in the modern cloud native stack. These speculations are not irrelevant as in recent years, the corporate IT network perimeter as we knew it is diminishing, and the concept has been shifted to data, identity, and compute perimeter. Software-defined networking solutions have overtaken hardware firewall boxes, and the requirement of managing bare metal servers has shifted to container deployed or even serverless applications. Where do bastions fit in these scenarios? Do we even need one?

By definition, bastions are a fortified checkpoint to counter or contain a threat. The concept of bastions can be applied to the real life fortification of a place or a building or a computer network.
