TL;DR – Last Week’s Container News (1/27/17–2/3/17)
Tutorials & How-Tos: Docker on Triton
Docker on Triton Tutorial — Joyent’s “Triton” allows containers to run on bare metal, bypassing the need for VMs. According to Joyent, benefits of this approach include easier application management, quicker scaling, and more optimal resource use. However, according to Joyent, the “prevalence of VM-based infrastructure” may cause users to “think within the limitations and confines of the VM.” Their 2/2/17 blog post, “Optimizing your Docker operations for Triton,” is a guide to help users escape the VM mindset, and navigate the transition from Docker in VMs to Docker on Triton.
Products & Features: Twistlock, Platform9 Managed Kubernetes & Fission, Photon Kubernetes
Twistlock — A 1/31/17 episode of The New Stack Makers podcast featured Twistlock, a container security platform. Twistlock features “environment checks, policy enforcement, and role-based access control,” and can check images to alert developers when an aspect of their image is non-compliant.
Managed Kubernetes & Fission — Platform9 has launched a managed service for Kubernetes (meant to simplify Kubernetes) and an “open source serverless framework” called Fission. The latter helps escape “single-source vendor lock-in” by providing an alternative to AWS Lambda. Check out the 1/27/17 episode of The New Stack Makers for insight into both of these products.
Photon Kubernetes — Last week, VMWare said they were launching, “a beta of a project that will link [VMWare’s container host] Photon to the Kubernetes container orchestration engine by way of Kubernetes’ own Container Network Interface,” according to The New Stack. This means, “Kubernetes should be able to support network microsegmentation directly,” and, “through the Kubernetes interface, you are now able to create networking and segmentation policies, which are delivered by [VMWare’s network virtualization platform] NSX.” Check out The New Stack’s coverage here: VMWARE PHOTON KUBERNETES NSX
Insight & Analysis: APMs and Microservices, Joyent + Hart, Conductor Suggests Scalability Limits
APMs and Microservices — Can traditional Applications Performance Management (APM) platforms be extended to support microservices environments? That’s the focus of a 2/2/17 episode of The New Stack Context. The podcast delves into the differences between the simple applications typically supported by APMs, and the much more complex architecture of a cloud-native system.
Joyent + Hart “Fireside Chat” — Joyent CTO Bryan Cantrill recently sat down with Mo Alkady and Christopher Dickey, (both from Hart — a company in the healthcare space), to discuss challenges and new technologies. The discussion covers the practical problems of technological innovation in the healthcare industry, the problems of technological innovation broadly, and some concerns specific to both Joyent and Hart.

Conductor Suggests Scalability Limits — A recent The New Stack editorial wonders if, “Netflix’s Open Source Orchestrator, Conductor, May Prove the Limits of Ordinary Scalability.” According to the article, “at the turn of the century… the orchestration argument centered around the nature of business transactions,” and, from the perspective to SOA architects, “a computing function could map to a business transaction.” However, the approach Netflix has taken with Conductor suggests that, “for computing processes to be more effective and viable at huge scales, they have to behave less and less like anything a rational businessperson would expect.”
