Message brokers are useful because the sender of a message does not always know who might want to receive that message. Message brokers can be used to implement the “publish/subscribe” pattern, and by centralizing the message workloads within the pub/sub system, it lets system operators scale

A single payment could involve 10 different networked services. If a payment fails, engineers need to be able to diagnose what happened. The root cause could lie in any of those services. Distributed tracing is used to find the causes of failures and latency within networked services. In a distributed trace, each period of time associated with
http://traffic.libsyn.com/sedaily/2018_04_20_BitcoinwithRogerVer.mp3Podcast: Play in new window | Download Bitcoin and Bitcoin Cash are two cryptocurrencies with similar properties. But the supporters of each of these Bitcoin versions have strongly divergent opinions on the direction of the Bitcoin project. At the center of this debate is the subject of block size.

http://traffic.libsyn.com/sedaily/2018_04_11_GowithErikStMartin.mp3Podcast: Play in new window | Download Go is a language designed to improve systems programming. Go includes abstractions that simplify aspects of low level engineering that are historically difficult—concurrency, resource allocation, and dependency management. In that light, it makes sense that the Kubernetes container orchestration system was written in Go. Erik St. Martin is a cloud developer advocate at Microsoft, where he focuses on Go and Kubernetes. He also

At both of these companies, the customer base was at a massive scale. At Dropbox, Tammy worked on the database that holds metadata used by Dropbox users to access their files. To call this metadata system simply a “database” is an understatement–it is actually a
http://traffic.libsyn.com/sedaily/2018_04_09_SREMikeHiraga.mp3Podcast: Play in new window | Download Software engineers have interacted with operations teams since software was being written. In the 1990s, most operations teams worked with physical infrastructure. They made sure that servers were provisioned correctly and installed with the proper software. When software engineers shipped bad code that took down a software company, the operations teams had to help recover the system—which often meant dealing with the physical

http://traffic.libsyn.com/sedaily/2018_03_28_Plasma.mp3Podcast: Play in new window | Download Ethereum is a system for running decentralized smart contracts. In the current implementation of Ethereum, every smart contract gets deployed to every full node. Whenever a user wants to call a smart contract, that smart contract gets executed on each full node–across the entire network. The current model for smart contract execution needs to be made more scalable. In today’s episode, Christian Reitwiessner
