PHP Microservices: Authentication and Authorization

With the complexity of microservices, security becomes a harder issue to address because there are so many areas to tackle the issue:

• At the network layer that normally involves private networks, VPNs, etc
• If Restful API, at the endpoint and is usually performed with OAuth or JSON WebTokens
• At the application layer that checks communication between microservices

This tutorial will ONLY focus on securely transmitting information between microservices using a token authentication. Token will be a single-use token and also authorize actions.
