Jonas Bonér, CTO of LightBend and creator Akka, discusses using Akka when developing distributed systems. He talks about the Actor Model, and how every Microservice needs to be viewed as a system to be successful. 

Why listen to this podcast:

 - Akka is JVM-based framework design for developing distributed systems leveraging the Actor Model - an approach for writing concurrent systems that treat actors as universal primitives and the most successful model with abstraction has been streaming
 - Circuit breakers in Akka are a backup and retry policy; they protect you by capturing failure data and allow you to roll back 
 - Every Microservice needs to be viewed as a system, it needs to have multiple parts that run on different machines in order to function and be fully resilient - thus is a Microsystem
 - Two different trends have emerged when it comes to hardware and environments: one is the trend toward Multi-core, the is a movement toward virtualized environments and the cloud
 - Saga pattern of managing long running transactions in a distributed system fits very well with messaging style architectures

Jonas Bonér on the Actor Model, Akka, Reactive Programming, Microservices and Distributed Systems

In this podcast, Matt Debergalis, Founder and CTO at Apollo, sat down with InfoQ podcast co-host Daniel Bryant. Topics discussed included: the motivations for GraphQL, the Apollo Data Graph platform, data modelling in an enterprise context, and how incrementally adopting GraphQL can help with decoupling the evolution of frontend and backend systems.


Why listen to this podcast:

 - The challenges of defining client-side-friendly data models, building maintainable and composable backend APIs, and moving data from the cloud to a client application contributes to making modern software development difficult and time consuming. 
 - GraphQL is an open-source data query and manipulation language for APIs, and a runtime for fulfilling queries with existing data. GraphQL lets application developers describe the data they need and bring that data into the screens that they are building for their users.
 - The Apollo Data Graph platform is a middleware layer that provides a way of decoupling the core business APIs from the client-side consumption patterns. Apollo can implement cross-cutting concerns, such as transaction management, which mitigates the need to implement this in (potentially multiple) client-side applications.
- Apollo makes it possible to build a “data graph”: a series of graphs that are composed from an organisation’s data for use within client-side applications. A data graph is especially valuable in larger enterprises because it is here that many (money making) systems with existing APIs need to be combined to meet new business requirements.
 - GraphQL can be adopted in an incremental fashion. To begin adoption just build the simplest possible graph that matches the needs of the first application, the first screen, or the first component that is required to transition over to the graph. Then let that graph evolve.
