Orchestrating Networks with Faucet and SLATE

Software Defined Networking (SDN) is an emerging technology that allows network administrators to programmatically manage network devices in a dynamic and cloud-like manner. Faucet is an SDN controller that utilizes the OpenFlow protocol to enable managing devices in such a way. We have been working on packaging Faucet as a SLATE application to empower sites to experiment with this exciting new technology. In this post, we’ll explain the process of configuring, deploying and connecting a Faucet controller through the SLATE platform.


SLATE Quarterly Updates

This is the first in our series of roughly quarterly release notes for activities in the SLATE project. We have a whole slew of changes across all aspects of SLATE, including a revamped web experience, client/server improvements, better tooling, more applications, and new sites added to the Federation.


Setting up a Kubernetes Cluster based on Singularity

Kubernetes supports multiple container runtimes through its Container Runtime Interface (CRI). As a result, besides the typical default choice of Docker (containerd) one can also use a variety of other drop-in replacements, such as cri-o. This article will discuss another option, namely Singularity.


Easy Network Diagnostics with SLATE

Network testing is hugely important to diagnose problems within and between sites. We’re trying to make network diagnostics dead simple with SLATE, and to do that we’ve SLATE-ified pieces of the excellent perfSONAR software stack. This application has recently landed into the SLATE stable catalog, and so we thought we would give you a little tour of this handy tool!


Presenting papers at PEARC19

Jason Stidd and Chris Weaver of the SLATE team both presented papers at PEARC19. The talks were on July 30 and July 31:

Developing and Operating Edge Services on Federated Infrastructure Using MiniSLATE (presentation)

Managing Privilege and Access on Federated Edge Platforms (presentation)


Application Security for the Edge

This whitepaper how applications are managed on a federated research platform. The intended end result is that an application administrator can deploy an application to an edge cluster in a trusted manner.


Building the SLATE Platform

We describe progress on building the SLATE (Services Layer at the Edge) platform.


Site Policies and Autonomy

An important principle in the management of edge services in research computing centers, and their ScienceDMZs, is autonomy.
