http://traffic.libsyn.com/sedaily/Shippable.mp3Podcast: Play in new window | Download Software deployment evolves over time. In the 90s, a “deployment” might have meant issuing a new edition of your software via CD-ROM. Today, a deployment is often a multi-stage process. A new software build will undergo automated unit tests and integration tests, before being deployed to users. The deployment might only go out to a small percentage of total users initially, with that
http://traffic.libsyn.com/sedaily/CassandraShum.mp3Podcast: Play in new window | Download Many companies are transitioning from a monolith to microservices architecture. Tools for cloud computing, containerization, and continuous delivery are making this easier. But there are still technological and organizational challenges that a company will encounter while making this transition. Cassandra Shum is an engineer with ThoughtWorks. She has worked with major financial institutions and other large companies to architect their migrations from monolith
http://traffic.libsyn.com/sedaily/developing_reactive_microservices_edited.mp3Podcast: Play in new window | Download The goals of microservices are the same as what we have pursued in software engineering for decades: isolation, decoupling, maintainability, scalability. The reason that we use the term microservices is not because we have a completely different idea of what a service is than we used to. We use the term microservices because we are signaling that we need to achieve these architectural
http://traffic.libsyn.com/sedaily/selfcontained_edited.mp3Podcast: Play in new window | Download Self-contained systems is an architectural approach that separates the functionality of a system into many independent systems. Each self-contained system is an autonomous web application, and is owned by one team. Communication with other self-contained systems or 3rd party systems is asynchronous where possible. As Eberhard Wolff explains in this episode, self-contained systems is not the same thing as microservices, but they are
http://traffic.libsyn.com/sedaily/cloudfountry_edited.mp3Podcast: Play in new window | Download Cloud Foundry is an open-source platform as a service. Companies use Cloud Foundry as a control plane to deploy and manage applications. It provides abstractions for microservices and continuous integration. Cornelia Davis joins the show to discuss Cloud Foundry. I interviewed her at the DevOps Enterprise Summit, where enterprises share their stories of improving their culture and their technology stack. Cornelia explained how
http://traffic.libsyn.com/sedaily/microservices_tools_edited.mp3Podcast: Play in new window | Download Microservices are a widely adopted pattern for breaking an application up into pieces that can be well-understood by the individual teams within the company. Microservices also allow these individual pieces to be scaled independently and updated in isolation. Past Software Engineering Daily episodes have covered the microservice architectures of Twitter, Netflix, Google, Uber and other companies. In today’s episode, I sit down with

Tech companies have a huge amount of work they need skilled employees for. Andela recruits the most talented technologists across Africa, shapes them into world-class software developers, and places them with tech companies worldwide such as Google and Microsoft. Brice Nkengsa is the director of engineering at Andela, and he joins the show to
http://traffic.libsyn.com/sedaily/distributed_tracing_edited_fixed.mp3Podcast: Play in new window | Download In a microservices architecture, a user request will often make its way through several different services before it returns a result to the end user. If a user experiences a failed request, the root cause could be in any of the services along that request path. Even more problematic is the challenge of debugging latency in this kind of request chain. Reshmi
http://traffic.libsyn.com/sedaily/github_edited_fixed.mp3Podcast: Play in new window | Download github has grown to have 10 million users and 30 million repositories. Getting to this scale has required innovation in many places–github has significantly altered the code for git itself, and has built unique infrastructure and written low level code to architect for git repository management at scale. Despite the need for cutting-edge technologies to support github, the development culture at github
http://traffic.libsyn.com/sedaily/Bouyant_Edited.mp3Podcast: Play in new window | Download Six years ago, Twitter was experiencing outages due to high traffic. Back in 2010 Twitter was built as a monolithic Ruby on Rails application. Twitter migrated to a microservices architecture to fix these problems. During this migration, the engineers at Twitter learned how to build and scale highly distributed microservice architectures. William Morgan was an engineer at Twitter during that time, and he

The process involves manufacturing, assembly lines, supply chains, and software at every step along the way. Today’s guests are Jim Sokoloff and Maarten Wensveen, who work on infrastructure and technology at Cimpress, a mass customization platform. Cimpress has t shirt printers, warehousing machines, supply chain management
http://traffic.libsyn.com/sedaily/Algorithmia_Edited.mp3Podcast: Play in new window | Download Algorithmia is marketplace for algorithms. A software engineer who writes an algorithm for image processing or spam detection or TF-IDF can turn that algorithm into a RESTful API to be consumed by other developers. Different algorithms can be composed together to build even higher level applications. Diego Oppenheimer is the CEO of Algorithmia, and he joins the show today to explain how Algorithmia

And how pieces of the system communicate will have a direct impact on how effective impact on how effective or efficient that organism or organization is.” In today’s episode, Ben Halpern interviews Juan Buritica, VP of Engineering at Ride.

Well, add a layer of abstraction.” Today’s guest is Calvin French-Owen, the CTO of Segment, a tool that companies use to aggregate their analytics into once place. As Segment has scaled, the company has had to restructure its etire technical architecture. Microservices, containers,
From Gajendra Choudhary‘s answer via Quora: Microservices architecture addresses many concern of application development but does not solve all the problems. It has its own advantages and limitations. In order to understand it fully, we need to understand one common architecture pattern in practice, i.e. Monolithic Architecture Monolithic architecture are highly tightly coupled and you can’t change something without impacting other. Look at this building and tell me how easy it
“You can have a monolith, and it can be a perfectly good thing.”
“By the time I joined, people were already starting to have this microservice fatigue.”
Distributed systems programming will always be a world of tradeoffs — there is no silver bullet in the future. But life can be made easier with tactics such as the actor pattern and the use of conflict-free replicated data types (CRDTs).
Caitie McCaffrey is a distributed systems engineer who currently works at Twitter. She previously worked on Halo 4 at Microsoft and 343 Industries. At QCon San Francisco, she will be hosting the track Taming Distributed Architecture.
What is DevOps? DevOps was an unclear term at the beginning of the week. Depending on who you ask, DevOps is: the agile manifesto applied to sysadmin the applied version of The Lean Enterprise the people who manage tools like Jenkins and containers Does the DevOps role actually exist? DevOps is a loose cultural thing, like agile. “DevOps” engineers are often software engineers or operations people that have been rebranded with minor change
http://traffic.libsyn.com/sedaily/docker_turnbull.mp3Podcast: Play in new window | Download Microservices on container architecture lead to effective workflows associated with DevOps. Docker containers wrap up a piece of software in a complete filesystem that contains everything it needs to run. This allows for quick flexibility and scaleability in business applications, a key driver of the DevOps methodology.
