In the last two decades public cloud has taken hold more and more so that an increasing number of companies has decided to migrate their workflows from their own, private, datacenters to a public cloud provider. Application development needs to be more adaptable as we transition to cloud solutions, creating a new cloud native approach consisting of microservice instead of monoliths. This led to important security challenges such as workload authentication. Following the cloud’s growth, new tools and models arose, like the Service Mesh and the Zero Trust paradigm. The first one is a dedicated infrastructure layer that you can add to your applications, allowing you to transparently add capabilities like observability, traffic management, and security, without adding them to your own code.
