  • Cloud Native Ambassadors and Docker Captains navigate users through the container ecosystemNavigating the container ecosystem can be confusing. Deciding where to dip your toes is challenging for those stepping into container and microservices waters. Even those who have already ventured knee-deep still wade through many questions as they progress in their cloud native journey. To help them guide them through the ecosystem, the Cloud Native Computing Foundation (CNCF) recently launched a Cloud Native Ambassadors program at its inaugural CloudNativeDay in Toronto.
  • Container Networking: A Breakdown, Explanation and AnalysisWhile many gravitate toward network overlays as a popular approach to addressing container networking across hosts, the functions and types of container networking vary greatly and are worth better understanding as you consider the right type for your environment.

  • Developer-defined application deliveryCloud-native applications are designed to draw upon the performance, scalability, and reliability benefits of distributed systems. Unfortunately, distributed systems often come at the cost of added complexity. As individual components of your application are distributed across networks, and those networks have communication gaps or experience degraded performance, your distributed application components need to continue to function independently.

  • Going Native with OpenStack Centric Applications: MuranoMurano is an OpenStack-native application catalog that allows application developers and cloud administrators to publish applications in a categorized catalog to be perused and deployed by application consumers. The selection of applications available within the catalog is intended to be that of released versions (ready-state) of applications (cloud-native or enterprise-architected), not application versions that are mid-development. Ideally, these are applications ready to be consumed and run by application users.

  • The Container Networking Landscape: CNI from CoreOS and CNM from DockerThere are two proposed standards for configuring network interfaces for Linux containers: the container network model (CNM) and the container network interface (CNI). Networking is complex, and there are many ways to deliver functionality. Arguments can be made as to which one is easier to adopt than the next, or which one is less tethered to their benefactor’s technology.
  • The Hybrid Evolution of ITIt’s a great time to be in Information Technology.” While this is a true statement, not everyone clearly understands why (or perhaps, has the fortitude to make it so). In the face of a massive movement to public cloud many in IT feel their value in the workplace eroding along with their identity. This feeling doesn’t need to be reality. Businesses are changing the way they operate and are transforming to leverage information technology more strategically. IT has a real opportunity to lead this transformation, not let the transformation happen to them.

  • Understanding Container NetworkingMuch of what container networking is today revolves around core Linux network technologies, whether that be iptables for port-forwarding, firewalling and network address translation, or ipvs for load-balancing and service abstraction (virtual IP addressing). These battle-tested technologies are old friends of systems engineers, who have leveraged these kernel capabilities as they’ve built container engines and orchestrators.

  • What is the Moby Project?Being an Austinite, I enjoyed having DockerCon local and co-authored a guide to visiting Austin in the hopes that attendees would enjoy having DockerCon in Austin as well. During this installment of Dockercon, a few major announcements were made, including the Moby Project. So, what is the Moby Project? It's a framework to assemble specialized container systems without reinventing the wheel.
