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

Sander Mak and Wes Reisz discuss the Java module system and how adoption is going. Topics discussed on this podcast include Java modularity steps / migrations, green field projects, some of the concerns that caused the EC to initially vote no on Java 9, and a new tool for building custom JREs called JLink. Additionally, as Java 10 was recently released a short bit at the end was added to discuss some of the latest news with Java.

Why listen to this podcast:

• People quickly moved to Java 8 because of features like Streams and Lambdas. Java 9 has a different story around modularity and application architecture. Adoption is slower and more intentional.
• Migrating large codebases to use modularity is hard. Many of the projects using modules are greenfield, and those large codebases that are moving now are most often using the classpath.
• Jlink is a new command line tool released with Java 9. It allows developers to create their own lightweight, customized JRE for a module-based Java application.
• Java version scheme has dropped the 1.* prefix. Future releases of the JDK will have the version number and follow the form *.0.1 (i.e. 9.0.1)
• While the module system will likely show it’s benefit mostly for new development, many 3rd party libraries are moving to adopt modularity and removing their dependencies on JDK internal APIs. It’s improving the experience for teams adopting modularity.
• There are no known open JEPS regarding the enhancement of the Java module system.
• Java 10 has been released. The release features changes to the freely available Java versions, local variable type inference (var), experimental GRAAL JIT compiler, application class data sharing, improved container support/awareness, and others.

Sander Mak on the Java Module System

Wes Reisz sits down and chats with Uncle Bob about The Clean Architecture, the origins of the Software Craftsperson Movement, Livable Code, and even ethics in software. Uncle Bob discusses his thoughts on how The Clean Architecture is affected by things like functional programming, services meshes, and microservices.

Why listen to this podcast:

* Michael Feathers wrote to Bob and said if you rearrange the order of the design principles, it spells SOLID.
* Software Craftsperson should be used when you talking about software craftsmanship in a gender-neutral way to steer clear of anything exclusionary.
* Clean Architecture is a way to develop software with low coupling and is independent of implementation details.
* Clean Architecture and Domain Driven Design (DDD) are compatible terms. You would find the ubiquitous language and bounded context of DDD at the innermost circles of a clean architecture.
* Services do not form an architecture. They form a deployment pattern that is a way of decoupling and therefore has no impact on the idea of clean architecture.
* There is room for “creature comforts” in a code base that makes for more livable, convenient code.
* “We have no ethics that are defined [in software].” If we don’t find a way to police it ourselves, governments will. We have to come up with a code of ethics.

Uncle Bob Martin on Clean Software, Craftsperson, Origins of SOLID, DDD, & Software Ethics

Vaughn Vernon is thought-leader in the space of reactive software and Domain Driven Design (DDD). Vaughn has recently released a new open source project called vlingo. The platform is designed to support DDD at the framework and toolkit level. On today’s podcast, Vaughn discusses what the framework is all about, why he felt it was needed, and some of the design decisions made in developing the platform, including things like the architecture, actor model decisions, clustering algorithm, and how DDD is realized with the framework.

Why listen to this podcast:

 - Vlingo is an open source system for building distributed, concurrent, event-driven, reactive microservices that supports (at the framework level) Domain Driven Design.
 - The platform is in the early stages. It runs on the JVM. There is a port to C#. All code is pushed up stream.
 - The platform uses the actor model and all messages are sent in a type-safe way.
 - Vlingo supports clustering and uses a bully algorithm to achieve consensus.

Vaughn Vernon on Developing a Domain Driven Design first Actor-Based Microservices Framework

This week on the InfoQ Podcast, Wes Reisz talks to Tanya Reilly (Principal Engineer at Squarespace and previously a staff SRE at Google). Tanya discusses her research into how the fire code evolved in New York and draws on some of the parallels she sees in software. Along the way, she discusses what it means to be an SRE, what effective aspects of the role might look like, and her opinions on what we as an industry should be doing to prevent disasters. This podcast features discussion on paved roads, prevention, testing, firefighting (in software), and reliability questions to ask throughout the software lifecycle.

Why listen to this podcast:

- Teams increasingly   are responsible for the entire software lifecycle. When this happens, they think about the software differently because they know their the ones that will get paged if it fails. This idea is at the core of the “You Build It, You Run It” philosophy in DevOps.
- The role of SRE is to define how to do things in a really reliable way. The focus is to make the majority of the operations work go away, and, for the things that can’t go away, it’s as easy as possible.
- At the very start of a project (when you’re writing the initial design), you should be thinking about the dependencies for a system and how will those that follow with be able to determine that. A great way to do this is to offer an API that people will want to use and then instrument it.
- We can learn a lot from the growth of fire safety regulations as metaphors for software, including: fireproof interior walls, socializing best practices, software inspections, and circuit breakers are all examples.
- The work SREs do varies in many places. SREs range from making recommendations on patterns to library creators in other areas. Occasionally, SREs are firefighters of last resort. In these cases, they’re the last resort though.
- We use error budgets and SLOs to quantify how many much risk we’re comfortable taking. It’s used to inform how much less (or more risk) we’re willing to take on.
- We need to consider software reliability throughout the full cycle of software development. When you build systems. Think about as if there will not be someone on call for it .

Tanya Reilly on Site Reliability Engineering and the Evolution of the New York City Fire Code

On this podcast, Wes talks to John Xmas. Johnny works for Kasada, a company that offers a security platform to help ensure only your users are logging into your web applications. Johnny is a well-known figure in the security space. The two discuss common attack vectors, the OWASP Top 10, and then walk through what hackers commonly do attempting to compromise a system. The show is full of advice on protecting your systems including topics around Defense in Depth, Time-Based Security, two-factor authentication, logging/alerting, security layers, and much more.

Why listen to this podcast:

 - While there are sophisticated web attacks out there that use things like PhantomJS or Headless Chome, the vast majority of the web application attacks are the same unsophisticated scripted attacks that you always hear about. These are simple scripts using tools like curl and BurpSuite with Python or JavaScript. These simple scripts are still incredibly effective.
 - OWASP Top 10 really hasn’t changed all that much in the last ten years. For example, despite being the number one approach used to educate defensive engineers on how to protect their apps, SQLI (SQL Injection) is still the most common attack. We continue to repeat the same mistakes that have exposed systems for a decade now.
 - Phishing is by and far the quickest way to compromise a system. Defensive in Depth, security boundaries, limiting local admin rights are all things that corporations can implement to minimize the blast radius.
 - Attackers have hundreds of gigs of actual username/password combinations that have been exposed from all the breaches over the past few years. These are often a first step when attempting to compromise a system. It’s more often likely that they will figure out a valid email pattern for a company and then feed actual names into that pattern to go after the username. From there, brute force attacks with those usernames against libraries of passwords is a common approach.
 - A common approach is to go after an email login. While the email can be a treasure trove of information, it’s more about using those credentials in other places. It’s pretty common, for example, to use those credentials to get into a network with a VPN.
 - Captcha/reCaptcha is not very effective and preventing these brute force attacks. There are a large number of bypasses and even Mechanical Turk companies that are available to bypass these tools. What can be effective is Time Based Security because it slows the attackers down. If you can slow them down, you can make the attack say long to succeed that they’ll go somewhere else.
 - Once inside the network, most companies often have little security on internal systems. Multi-factor authentication, not just on the front door, but on internal systems is a huge step in the right direction. Monitoring not only for failed login attempts but, in some situations, valid login attempts (such as when a domain admin logs into a domain controller) should absolutely be used.
 - When it comes to application security between services within a network, the best advice is to make sure developers really understand what is trying to be accomplished by something like JWT (JSON Web Tokens). Often its the lack of understanding of what they’re actually doing that leads to system vulnerabilities.
