  • Investigating Near Misses to Prevent Disasters: QCon London Q&A

    Investigating near misses by gathering data from the field and exploring anything that looks wrong or is a bit odd can help to prevent disasters, said Ed Holland, software development manager at Metaswitch Networks. At QCon London 2019 he gave a talk about avoiding being in the news by investigating near misses.

  • Mature Microservices and How to Operate Them: QCon London Q&A

    Microservices is an architectural approach to keep systems decoupled for releasing many changes a day, said Sarah Wells in her keynote at QCon London 2019. To build resilient and maintainable systems you need things like load balancing across healthy nodes, backoff and retry, and persistence or fanning out of requests via queues. The best way to know whether your system is resilient is to test it.

  • Reconciling Kubernetes and PCI DSS for a Modern and Compliant Payment System

    Ana Calin, systems engineer at Paybase, gave an experience report at QCon London [slides PDF] on how the end-to-end payments service provider solution managed to achieve PCI DSS level 1 compliance (the highest) with 50+ Node.js microservices running on Google Cloud Kubernetes Engine (GKE), and using Terraform for infrastructure provisioning and Helm for service deployment.

  • Discovering Culture through Artifacts: QCon London Q&A

    Behavior and values are two critical components to organizational culture; values denote what the organization believes in, and behaviors are rooted in those values, argued Mike McGarr, engineering leader at Slack. At QCon London 2019 he spoke about improving your understanding of an organization’s culture, the key components of culture, and what to look for in order to learn about the culture.

  • Design and Security in Agile: QCon London Q&A

    Reviews of design diagrams by domain experts can detect potential security breaches not found by vulnerability scans or security automation. Such reviews should focus on critical functions like issuing and managing access tokens, transferring data to external services, and running untrusted code, said Kevin Gilpin, enterprise software engineer and co-founder of AppLand, at QCon London 2019.

  • Protocols are Important: Martin Thompson at QCon London

    The protocols we use should be studied and practiced more, they are really important in many aspects, Martin Thompson claimed in his presentation at QCon London 2019, where he first looked back at the evolution of mankind and argued that protocols is the most significant human discovery, and then did a critical analysis of the protocols and ideas we use today.

  • A Description of RSocket and Its Communication Model: Robert Roeser at QCon London

    RSocket is an asynchronous network communication protocol where communication is modelled as multiplexed streams of messages over a single network connection. In a presentation at QCon London 2019, Robert Roeser explained the reasons for creating RSocket and the communication model it uses. In the same presentation, Ondrej Lehecka described two use cases, and Andy Shi ran a demo using RSocket.

  • Designing and Building a Resilient Serverless System: John Chapin at QCon London

    In a presentation at QCon London 2019, John Chapin explained the basics of serverless technologies and how to architect and build a resilient serverless system. He also ran a demo of a how a globally distributed, highly available application can be built and run in multiple regions on AWS.

  • A Critical Look at Event-Driven Systems: Bernd Rücker at QCon London

    There is currently a hype in adoption of event-driven systems. Sometimes they are almost seen as the “magic thing” in our strive for decoupled systems, Bernd Rücker noted at the recent QCon London 2019. In his presentation he took a critical look at three common hypotheses around event-driven systems: events decrease coupling, Orchestration needs to be avoided, and Workflow engines are painful.

  • Recommendations When Starting with Microservices: Ben Sigelman at QCon London

    During the years Ben Sigelman worked at Google, they were creating what we today call a microservices architecture. Some mistakes were made during this adoption, which he believes are being repeated today by the rest of the industry. In his presentation at QCon London 2019, Sigelman described his recommendations to avoid making these mistakes when starting with microservices.

  • How Airbnb Simplified the Kubernetes Workflow for 1000+ Engineers

    Melanie Cebula talked about the internal tooling and strategies Airbnb adopted to support over 1000 engineers concurrently configuring and deploying over 250 critical services to Kubernetes. One key enabler was a layer of abstraction and generation of Kubernetes configuration from higher level primitives using standardized environments and namespaces (and automated validations whenever possible).

  • Building Services at Scale at Airbnb: QCon London Q&A

    The re-architecture to SOA at Airbnb improved the performance of the services and site reliability. Faster build and deploy times led to increased developer productivity, and improving clarity and boundaries for ownership increased efficiency. Jessica Tai, a software engineer at Airbnb, presented Airbnb’s Great Migration: Building Services at Scale at QCon London 2019.

  • How to Grow Teams That Can Fail without Fear: QCon London Q&A

    Blameless failure starts with building a culture where failure is acknowledged, shared, investigated, remedied, and prevented, said Emma Button, a DevOps and cloud consultant, at QCon London 2019. Visualising the health and state of your system with CI/CD practices can increase trust and ownership and invite people to help out when things fail.

  • The Risk of Climate Change and What Tech Can Do: QCon London Q&A

    Data centres create more emissions than the aviation industry due to energy usage and 24x7 availability, and the growth of the cloud computing and mining of cryptocurrencies is increasing the impact technology has on our climate. Moving existing servers to providers who use renewable sources of electricity could lead to planet-wide climate improvements. A QCon Q&A with Jason Box and Paul Johnston.

  • Tracks Announced! QCon London 2019 (March 4-8, 2019)
