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, Daniel Bryant sat down with Bryan Liles, senior staff engineer at VMware. Topics covered included: the challenges with deploying applications into Kubernetes, using the open source Octant tool to increase a user’s understanding of Kubernetes clusters, and how “serverless” technologies may influence the future approaches to building software.

Why listen to this podcast:

 - Octant is a highly extensible platform for developers to better understand the complexity of Kubernetes clusters. Octant runs locally, using the local Kubernetes credentials. It currently displays information about a Kubernetes cluster and related applications as a web page. Soon this tool and resulting display will be provided as a standalone application.
 - The goal of Octant is to enable users to discover what they need to discover. The tool aims to provide context relevant to where a user is and what they are trying to achieve. The Octant plugin system allows integration with other tooling, such as logging and metrics frameworks. This aims to facilitate quick problem detection and resolution.
 - Cloud native platforms like Kubernetes are complicated, as there are lots of moving parts. The most important challenge to be tackled to increase the adoption of platforms like Kubernetes is “how do we move code from our IDEs to wherever it needs to run with the least amount of friction?”. Testing needs to be implicit, as does security verification, and the acts of deployment. Kubernetes needs its “Ruby on Rails” moment.
 - Creating “serverless” systems is an interesting approach, but we may currently be using this technology in a non-optimal way. For example, creating web applications using this technology enables scalability, but can lead to the creation of difficult to understand systems that also require a lot of boilerplate configuration. Arguably, a more interesting use case is implementing large-scale batch processing using simple event-driven models.
- The Cloud Native Computing Foundation (CNCF) has created a series of communities of practice called Special Interest Groups (SIGs), such as SIG App Delivery. This allows folks with similar interests to work together as a community, focusing on solving a specific set of well-scoped problems. There are many ways to get involved, from discussions, to coding and creating documentation.
