The InfoQ Podcast

Wesley Reisz talks with Sam Newman about microservices. They explore the current state of the art with regards the architectural style and corresponding tooling and deployment platforms. They then discuss how microservices increase the surface area of where sensitive information can be read or manipulated, but also have the potential to create systems that are more secure. Why listen to this podcast: - Different organisations have different risk appetites for new technology, so what may be appropriate for one organisation may not be appropriate technology choices for another. - If you are deploying micro services then you need to know why you are doing it and what benefits you expect to get from deploying them. - Micro services are defined by their independently deployable units rather than their size. - Using a cryptographic token that is verifiable off line is a common pattern for passing authentication contexts around to different services. - Serverless architectures redeuce the need to monitor server patching but does not diminish the need for monitoring application runtime or library dependencies from security patching.

In this podcast Charles Humble talks to Sylvan Clebsch, who is the designer of the actor-model language Pony programming and now works at Microsoft Research in Cambridge in the Programming Language Principles group. They talk about the inspirations behind Pony, how the garbage collector avoids stop-the-world pauses, the queuing systems, work scheduler, and formal verification. Why listen to this podcast: * Pony scales from a Raspberry Pi through a 64 core half terabyte machine to a 4096 core SGI beast * An actor has a 256-byte overhead, so creating hundreds of thousands of actors is possible * Actors have unbounded queues to prevent deadlock * Each actor garbage collects its own heap, so global stop-the-world pauses are not needed * Because the type system is data-race free, it’s impossible to have concurrency problems in Pony More on this: Quick scan our curated show notes on InfoQ http://bit.ly/2tZXcKE You can also subscribe to the InfoQ newsletter to receive weekly updates on the hottest topics from professional software development. bit.ly/24x3IVq Subscribe: www.youtube.com/infoq Like InfoQ on Facebook: bit.ly/2jmlyG8 Follow on Twitter: twitter.com/InfoQ Follow on LinkedIn: www.linkedin.com/company/infoq Want to see extented shownotes?

Wesley Reisz talks to Sid Anand, a data architect at cybersecurity company Agari, about building cloud-native data pipelines. The focus of their discussion is around a solution Agari uses that is built from Amazon Kinesis Streams, serverless functions, and auto scaling groups. Sid Anand is an architect at Agari, and a former technical architect at eBay, Netflix, and LinkedIn. He has 15 years of data infrastructure experience at scale, is a PMC for Apache Airflow, and is also a program committee chair for QCon San Francisco and QCon London. Why listen to this podcast - Real-time data pipeline processing is very latency sensitive - Micro-batching allows much smaller amounts of data to be processed - Use the appropriate data store (or stores) to support the use of the dataIngesting data quickly into a clean database with minimal indexes can be fast - Communicate using a messaging system that supports schema evolution More on this: Quick scan our curated show notes on InfoQ http://bit.ly/2rJU9nB You can also subscribe to the InfoQ newsletter to receive weekly updates on the hottest topics from professional software development. bit.ly/24x3IVq Subscribe: www.youtube.com/infoq Like InfoQ on Facebook: bit.ly/2jmlyG8 Follow on Twitter: twitter.com/InfoQ Follow on LinkedIn: www.linkedin.com/company/infoq Want to see extented shownotes?

Wesley Reisz talks to Sachin Kulkarni, Director of Engineering at Facebook, about the engineering challenges for Facebook live, and how it compares to the video upload platform at Facebook. Why listen to this podcast: - Facebook Infrastructure powers the board family of apps including the Facebook app, Messenger and Instagram. It is largely a C++ shop. There is some Java and Python, and the business logic is all done in PHP. The iOS apps are written in Objective C and the Android apps are in Java. - The video infra team at Facebook builds the video infrastructure across the whole company. Projects include a distributed video encoding platform which results in low latency video encoding, video upload and ingest. - Facebook Live does encoding on both the client and the server. The trade-off between encoding on the client side and the server side is mostly around the quality of the video vs. latency and reliability. - Facebook gets around 10x speed-up by encoding data in parallel compared to serial. - They also have an AI-based encoding system which resulted in 20% smaller files than raw H.264.

Wesley Reisz talks to Martijn Verburg, co-founder of the London Java Community and CEO of jClarity, about the JCP EC “no” vote on the Java Platform Module System (JPMS), which is due to be shipped as part of Java 9. The talk about what JPMS offers, how it works, what the no vote means and what happens next. Why listen to this podcast: - Jigsaw isn’t dead - The “no” vote was based on the submission being a bit early, and without expert group consensus that it should be submitted - Since the vote started, several amendments have been made which addressed some of the concerns listed by those who voted “no” - Daily calls with the expert group and interested parties will work to resolve the outstanding issues promptly - A resubmission is due within 30 days with a future vote expected to go through More on this: Quick scan our curated show notes on InfoQ http://bit.ly/2q20esc You can also subscribe to the InfoQ newsletter to receive weekly updates on the hottest topics from professional software development. bit.ly/24x3IVq Subscribe: www.youtube.com/infoq Like InfoQ on Facebook: bit.ly/2jmlyG8 Follow on Twitter: twitter.com/InfoQ Follow on LinkedIn: www.linkedin.com/company/infoq Want to see extended shownotes?

Wesley Reisz talks to Daniel Bryant on moving from monoliths to micro-services, covering bounded contexts, when to break up micro-services, event storming, practices like observability and tracing, and more. Why listen to this podcast: - Migrating a monolith to micro-services is best done by breaking off a valuable but not critical part first. - Designing a greenfield application as micro-services requires a strong understanding of the domain. - When a request enters the system, it needs to be tagged with a correlation id that flows down to all fan-out service requests. - Observability and metrics are essential parts to include when moving micro-services to production. - A service mesh allows you to scale services and permit binary transports without losing observability.

Rossen Stoyanchev talks to Wesley Reisz about blocking and non-blocking architectures, upcoming changes in Spring including Spring WebFlux, the reactive web stack in Spring framework 5, due this summer. He also discusses the differences between rxJava and Reactor. Why listen to this podcast: - Spring Framework 5 is due to be released June 25 2017 - Spring Web Flux provides a web programming model designed for asynchronous APIs - Back-pressure is important in a server environment; less so within a UI environment - It’s possible to use a Spring Web Flux client within a Spring MVC applciation - Managing sets of thread pools is more complicated than having a scalable asynchronous system More on this: Quick scan our curated show notes on InfoQ http://bit.ly/2pPgq0G You can subscribe to the InfoQ newsletter to receive weekly updates on the hottest topics from professional software development. bit.ly/24x3IVq Subscribe: www.youtube.com/infoq Like InfoQ on Facebook: bit.ly/2jmlyG8 Follow on Twitter: twitter.com/InfoQ Follow on LinkedIn: www.linkedin.com/company/infoq Want to see extented shownotes?
