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 Joe Duffy, founder and CEO at Pulumi, and discussed several infrastructure-themed topics: the evolution of infrastructure as code (IaC), the way in which the open source Pulumi framework allows engineers to write IaC using general purpose programming languages such as JavaScript and Go, and the future of multi-cloud environments.

Why listen to this podcast:
●	Infrastructure as Code (IaC) enables engineers to programmatically define the configuration and provisioning of computing infrastructure, on-premises hardware, and cloud services. 
●	Traditional IaC tools were often imperative, requiring engineers to define and enumerate the necessary steps and SDK calls in order to configure the underlying infrastructure. 
●	Modern IaC tools like HashiCorp’s Terraform, AWS CloudFormation and other related cloud vendor tooling enable engineers to write declarative code to define a required state of the infrastructure. The tools parse the declarative configuration and take appropriate action to enact the specified state, for example, calling SDKs and APIs, verifying results, iterating etc.
●	Pulumi is an open source framework that enables engineers to define IaC using general purpose programming languages, such as Node, Python, .NET Core, and Go.
●	Pulumi allows imperative specification of IaC. Engineers can use their favourite language-specific features, idioms, and patterns. The use of language modules, packages, and libraries can also enable code reuse.
●	Under the hood, Pulumi transforms code written in the supported languages to a declarative specification model. This model is then used to enact the required infrastructure state.
●	Frameworks like Pulumi enable engineers to deploy and configure infrastructure across multiple cloud vendors and services (including Kubernetes clusters).
