Healthcare is a complex business. Oscar is a company that wanted to build a new insurance provider–but realized that healthcare is so interconnected that in order to build a new insurance provider, realized it actually needed to build an entire healthcare business too, complete with patient management and facilities.

Since Oscar is a modern technology company, the focus on customer service, engineering, and data management offers an optimistic view into what healthcare might look like in the near future.

Every time a patient interacts with the healthcare system, their insurance provider collects data on that interaction. Isaac Councill helped architect the infrastructure at Oscar that manages and analyzes the patient data. In this show, we talk about the healthcare system, data engineering, and Apache Mesos, which Oscar uses to manage its applications.

Many companies are transitioning from a monolith to microservices architecture. Tools for cloud computing, containerization, and continuous delivery are making this easier. But there are still technological and organizational challenges that a company will encounter while making this transition.

Cassandra Shum is an engineer with ThoughtWorks. She has worked with major financial institutions and other large companies to architect their migrations from monolith to microservices. Also, she regularly puts on workshops to engineers who are seeking to make this migration at the company they work at.

In this episode, she describes some of her experiences and recommendations around transitioning from a monolith to microservices.

Firebase is a backend-as-a-service. The key efficiency of a backend-as-a-service is that it enables developers to go from having a 3-tier architecture (client, server, database) to a 2-tier architecture (client, backend-as-a-service).

The team who started Firebase built it as a pivot. They had started a social network, and then they realized there wasn’t a good backend for chat tools. And so they started a chat-as-a-service tool, for people who wanted to include chat in their applications. And that led them to the fundamental realization that chat is actually representative of a broader category of real-time synchronization problems. Firebase was eventually acquired by Google.

Doug Stevenson is a senior developer advocate with Google and the host of Meet Firebase, a YouTube talk show about Firebase. It was a pleasure to sit down for a conversation with him, especially because I recently started using Firebase in my own application as a backend for real-time chat.

Spring Framework is an application framework for Java and JVM languages. Spring was originally built around dependency injection, but grew to become an entire ecosystem of tools and plugins for Java developers.

Spring was originally released 15 years ago, and since then a lot has changed around application development. For example, many engineers deploy applications to the cloud in microservices architectures. The expectations around frameworks has also changed, with the rise of Django, Ruby on Rails, and NodeJS.

Spring Boot takes an opinionated view of building production-ready Spring applications. By taking an opinionated view, Spring Boot gets engineers up and running faster than the traditional Spring framework. Josh Long is a Spring Developer Advocate at Pivotal and he joins the show to discuss Spring Boot and the history of the Spring Framework.

Software Engineering Daily is having our third Meetup, Wednesday May 3rd at Galvanize in San Francisco. The theme of this Meetup is Fraud and Risk in Software. We will have great food, engaging speakers, and a friendly, intellectual atmosphere. To find out more, go to softwareengineeringdaily.com/meetup. We would love to get your feedback on Software Engineering Daily. Please fill out the listener survey, available on softwareengineeringdaily.com/survey.
