Open Service Mesh: A Service Mesh Implementation from Microsoft
Microsoft has released open service mesh (OSM), an alpha service mesh implementation compliant with the SMI specification. OSM covers standard features of a service mesh like canary releases, secure communication, and application insights, similar to other service mesh implementations like Istio, Linkerd, or Consul. Additionally, the OSM team is in the process of donating the project to the CNCF. → Read More
How Amazon Teams Do Continuous Delivery
An AWS engineer recently wrote about how Amazon deployment pipelines look and what practices they follow to deploy continuously to production. A pipeline validates changes in multiple environments running unit and integration tests, and use stages to stagger deployments to production. Teams don't actively examine deployments as the pipeline monitors key metrics and can rollback if needed. → Read More
Cloud Development Kit Can Now Generate Terraform Configurations Using TypeScript and Python
AWS, HashiCorp, and Terrastack collaborated to release a preview of the CDK for Terraform, or cdktf. Developers can use programming languages like Python or Typescript to manage infrastructure as code. cdktf generates a Terraform configuration in JSON. Also, cdktf supports any existing modules and providers from the Terraform registry to deploy resources to AWS, Azure, or Google Cloud. → Read More
Why Coinbase Is Not Using Kubernetes to Run Their Container Workloads
Coinbase recently wrote about why Kubernetes is not part of their technology stack. Coinbase uses containers, but they run them in VMs. For deployments, they use Odin, its open-source solution for deploying their services in VMs as auto-scaling groups. Adopting Kubernetes adds unnecessary complexity to their current deployment pipeline, and it is not the right tool for them at the moment. → Read More
Krustlet: A kubelet Written in Rust to Run WebAssembly Workloads in Kubernetes
Deis Labs has released Krustlet, an open-source Kubernetes kubelet written in Rust to run web assembly workloads within Kubernetes. Krustlet initial version is functional to run an essential workload as it doesn't have support for features like pod events or Init Containers yet. Applications must implement the WebAssembly system interface (WASI) as Krustlet only runs WebAssembly containers. → Read More
Q&A on the Compose Specification Community
Docker released a community for developing the Compose specification to help developers build cloud-native applications using compose. There've been different implementations of Docker compose to make it work in platforms like Kubernetes or AWS ECS. But Docker wants to work with the community to provide better support and define the future of Compose. → Read More
Managing Infrastructure From Kubernetes with the HashiCorp Terraform Operator
HashiCorp has released the alpha version of Terraform operator for Kubernetes to manage infrastructure as code calling Terraform Cloud from Kubernetes. After installing the operator, users can synchronize Terraform workspaces using Kubernetes manifests. Then, applications running in Kubernetes can reference Terraform outputs using ConfigMaps. For now, this operator only works for Terraform Cloud. → Read More
Reimagining CI/CD Pipelines as Composable Blocks with Bryan Liles
Bryan Liles, Senior Staff Engineer at VMWare, talked at the DeliveryConf for ideas about patterns and recommendations when building CI/CD pipelines. Liles recommends thinking about CI/CD as patterns instead of implementations, like merely using Jenkins or Spinnaker. It should be possible to build a platform with composable blocks with replaceable components and agnostic to a technology stack. → Read More
How Team Interactions Help Kubernetes Adoption With Manuel Pais at QCon London
Manuel Pais talked at QCon London about how team interactions are vital to reduce cognitive load to have a successful adoption of Kubernetes. Pais recommends having a digital platform on top of Kubernetes. And, organizations can get started by assessing the team's cognitive load, defining a digital platform, and setting clear team interactions. → Read More
Exploring Costs of Coordination During Outages With Laura Maguire at QCon London
Laura Maguire talked at QCon London about how the coordinative efforts during outages cause a high cognitive cost. Maguire found out that coordination during anomaly response is difficult, that existing models can undermine speedy resolution, and that the strategies to control the cost of coordination are adaptive to the type of incident. Moreover, tooling has additional costs of coordination. → Read More
What Comes After Microservices? Multi-Runtime Microservices With Bilgin Ibryam at QCon London
Bilgin Ibryam talked at QCon London about the evolution of distributed systems on Kubernetes and the future architecture trends. Ibryam said that the next trend would be to decouple infrastructure concerns from microservices. Ibryam calls this multi-runtime microservices, a service with business logic along with a sidecar in charge of state management, networking, binding, and lifecycle. → Read More
How to Embrace “You Build It, You Run It” With Paul Hammant at QCon London
Paul Hammant talked at QCon London about having developers responsible for the first line of support in production, as the saying goes, “if you build it, you run it.” Hammant recommends following this practice only if there are proper support levels and escalation policies defined. As a result, companies could reduce the chances of burnout or staff quitting. → Read More
DevOps Beyond Development and Operations With Patrick Debois at QCon London
Patrick Debois talked at QCon London about thinking of DevOps beyond development and operation silos. DevOps is inherently complex, and there are other risks, challenges, and bottlenecks outside the software delivery pipeline where collaboration is vital. For instance, when collaborating with other groups like suppliers, HR, marketing, sales, finance, or legal. → Read More
What Will the Next 10 Years of Continuous Delivery Look Like?
Dave Farley and Jez Humble talked at the DeliveryConf about their expectations for the next ten years of Continous Delivery (CD). For CD to succeed, the IT industry needs to focus on three performance aspects: technical, organizational, and cultural–all profoundly interrelated. DORA's report has shown that technical practices can lead the change, but they alone aren't enough. → Read More
WKSctl: A Tool for Kubernetes Cluster Management Using GitOps
WKSctl is an open-source project to install, bootstrap, and manage Kubernetes clusters, including add-ons, through SSH. WKS is a provider of the Cluster API (CAPI) using the GitOps approach. Kubernetes cluster configuration is defined in YAML, and WKSctl applies the updates after every push in Git, allowing users to have repeatable clusters on-demand. → Read More
How Twitter Improves Resource Usage With a Deterministic Load Balancing Algorithm
Twitter recently shared the details of why their RPC framework Finagle implements a client-side load balancing using a deterministic aperture algorithm for their microservices architecture. Twitter ran different experiments but confirmed that with a deterministic approach, requests are better distributed, connections count reduces drastically, and they even need less infrastructure. → Read More
