  • eBPF and the Service Mesh: Don't Dismiss the Sidecar Yet

    While eBPF looks promising to improve service mesh sidecar proxy performance, there are other, simplier ways to improve performance. The layer 7 processing needed for service meshes is unlikely to be feasible in eBPF for the foreseeable future, which means that meshes will still need proxies.

  • Best Practices for Running Stateful Applications on Kubernetes

    Running stateful applications on Kubernetes is not a common use-case but it is possible. This article covers a number of techniques for safely operating stateful applications on Kubernetes including the StatefulSet and DaemonSet controllers, secret management, ConfigMaps, and the effective use of namespacing.

  • Reducing Cloud Infrastructure Complexity

    Cloud computing adoption has taken the world by storm, and is accelerating unabated. According to Flexera’s annual State of the Cloud Report for 2020, 93% of respondents used multi or hybrid cloud strategies. This article examines different aspects of cloud infrastructure complexity, and approaches to mitigate it.

  • A Cloud-Native Architecture for a Digital Enterprise

    This article describes a vendor/technology-neutral reference architecture for a cloud native digital enterprise that can be mapped into different cloud-native platforms (Kubernetes and service mesh), cloud providers (Microsoft Azure, Amazon AWS, and Google GCP), and infrastructure services.

  • Edge Computing and Flow Evolution

    Edge computing echoes science from the field of complex adaptive systems that explains scaling patterns. Understand this science to make better decisions about what to run "on the edge."

  • Service Catalog and Kubernetes

    Cloud-native applications do not just live inside Kubernetes—they also benefit from using the available cloud managed services. Similar to Kubernetes' declarative object configuration model, the Open Service Broker API with the Service Catalog provides a declarative way to describe cross-platform/cross-cloud managed service dependencies.

  • Resilient Systems in Banking

    Resilience is about tolerating failure, not eliminating it. To build a resilient system, you must build a system that absorbs shocks, and continues or recovers. Following best practices for resilient architecture, including established cloud patterns, allowed Starling Bank to build a bank, from scratch, in a year, against a backdrop of highly public outages amongst incumbent banks.

  • Cloud Native Architectures - a Conversation with Matt Stine

    Rags Srinivas caught up with Matt Stine at the O'Reilly Architecture conference in Boston, MA. Matt talks about Cloud Native Architectures and some of the cultural and technological challenges. He talks about some of the NetFlix services and how Spring is wrapping it up to be able to architect and develop microservices on the platform. He also talks about SOA and what it probably missed out.
