Synopsis

The advent of reactive microservice architectures and the popularity of functional programming in recent years has prompted many companies to reconsider their traditional n-tier architectures. While traditional architectures served them well in the past, scalability, availability, and performance have become more of a concern to many organizations seeking to meet the ever-growing demands of their customers. To accomplish their goals, companies must also incorporate NoSQL and Agile DevOps into their architectures, resulting in a holistic solution that emphasizes automation and scalability.

Learning Objectives

  • Understanding reactive microservices
  • Agile DevOps using Ansible, Vagrant, and Docker
  • Developing a simple microservice application in Play or ACT framework
  • Securing microservices, encrypting data at rest, and using PKI/HMAC
  • Distributed caching and making full use of the HTTP protocol (CORS, HTTP/2, HSTS, Public key pinning)
  • Common practices/Best Practices for Microservices
  • Future of web development with web components and isomorphic JS
  • SaaS and multi-tenancy in microservices
  • Testing microservices

Prerequisite

  • Some programming knowledge in an imperative or functional programming language such as Java, .NET, PHP, etc.
  • Some background in software architecture
