Passing Go: polyglot Kubernetes Operators

Posted on: October 28, 2019October 28, 2019

Operators within Kubernetes are useful tools, designed to extend the container orchestration platform with additional resources. More directly, an Operator, sometimes referred to as custom controllers, is a method of packaging, deploying, and managing a Kubernetes application.

As useful as Operators are, they have had one limitation: originally they all had to be written in the Go programming language. Thanks to the Operator SDK, you do not need to develop your Operators in Go. The Operator SDK has options for Ansible and Helm that may be better suited for the way you or your team work. But, it can still be limiting for dev teams trying to build an operator if they don’t happen to be skilled in Helm or Ansible.

Diagnosing apps with AI

A well-known tactic for figuring out how to identify the root cause of a problem that has caused an outage in a production environment is to go back and see what the environment has been doing so far. Through the analysis of logs, developers and operators alike can determine usage information that ideally reveal what’s wrong with a given application or how it can be improved to work better.

In the early days of logging, there wasn’t a great deal of activity going on, so it was possible for a human being (or two) to examine such logs and figure out what was up. It didn’t hurt that the logs were not only sparse in content, but also not terribly complicated in terms of what they reported. Alerts such as “Help, my processor is melting” really didn’t take a lot to figure out how to fix. Applications now are more distributed and that further complicates the situation. But over time, logs got far more voluminous and more detailed in what they were reporting.

Managing chaos in a containerized environment

Quick, name some weird stuff that’s happened to your production machines.

Accidentally dropping a production database table? Rolling out a patch that enabled any user to log in with any password? Disabling a load balancer? Using a dictionary to physically keep keyboard keys depressed so “terminals [could] repeatedly [hit] the enter key in order for the logins and print jobs of about 40,000 people to work”?

It’s happened to Alex Corvin, a senior engineer at Red Hat. Well, not that last one. But Corvin has been around long enough in his career to have met Mr. Murphy and his Law: if it can go wrong, it will.

How Open Data Hub learners become the teachers

The prospect of true machine learning is a tangible goal for data scientists and researchers. It has been long known that the platform on which such ML apps can run have to be fast and hyper efficient so that learning can be that much faster. This is the motivation for Red Hat engineers in the Office of the CTO who are working to optimize such an open source platform: Open Data Hub.

Open Data Hub is built on Red Hat OpenShift Container Platform, Ceph Object Storage, and Apache Kafka/Strimzi integrated into a collection of open source projects to enable a machine-learning-as-a-service platform. That’s a lot of components to be integrated, and to ensure that their contributions to Open Data Hub perform well, Red Hat engineers have taken the step of creating an Internal Data Hub within Red Hat as a proving ground and learning environment.

Trust No One, Run Everywhere–Introducing Enarx

Posted on: August 16, 2019

Mike Bursell, Red Hat

When you run a workload as a VM, container or in a serverless environment, that workload is vulnerable to interference by any person or software with hypervisor, root or kernel access. Enarx, a new open source project, aims to make it simple to deploy workloads to a variety of trusted execution environments (TEEs) in the public cloud, on your premises or elsewhere, and to ensure that your application workload is as secure as possible.

When you run your workloads in the cloud, there are no technical barriers to prevent the cloud providers–or their employees–from looking into your workloads, peeking into the data, or even changing the running process. That’s because when you run a workload as a VM, container or serverless, the way that these are implemented means that a person or software entity with sufficient access can interfere with any process running on that machine.

Machine Learning with Open Source Infrastructure

As machine learning becomes more interesting to technology companies, it is hardly surprising that a company like Red Hat is going to approach the challenges of this aspect of artificial intelligence with an open source methodology in mind.

The immediate benefits to open source machine learning tools are plain as day to anyone familiar with how open source works: lower cost, more flexibility, no vendor lock-in… you know, the usual.

But dig a little deeper and it quickly becomes apparent that open source means more for cutting-edge software than just a faster way to get cheaper software.

Exploring Unsupervised Deep Learning

The concept of artificial intelligence, which seemed so much like science fiction a few decades ago, has made real, practical inroads in producing results that organizations can find useful. What’s making those results happen, though, isn’t esoteric pie-in-the-sky theory: it’s creating statistical models that have been trained to make decisions. And trained a lot.

Artificial intelligence itself is a term that, for now, has had less of a focus than the more results-oriented machine learning, where a computer system is given input and output data and then is directed to infer the mathematical rules that govern the transformation of that data.

“It’s like pointing a program to look at the solar system and then have it figure out the laws of motion that govern a planetary system,” explained Sanjay Arora.

Understanding and Applying Storage Federation Patterns Using KubeFed

Posted on: July 3, 2019July 3, 2019

Erin Boyd

As a cloud user, how do you avoid the pull of data gravity of one provider or another? How can you get the flexibility and tooling to migrate your infrastructure and applications as your needs change? How do you get to the future of storage federation as data agility?

In this blog we cover the primary motivations and considerations that drive the enablement of flexible, scalable, and agile data management. Our subsequent blogs cover practical use cases and concrete solutions for our 6 federated storage patterns.

All of this is grounded in Red Hat’s work to take a lead in multi-cluster enablement and hybrid cloud capabilities. Our work is focused on leading and moving forward projects that lay the groundwork for this vision in OpenShift, driven via the Kubernetes project KubeFed.

Keylime: Using TPM to Secure Your Slice of the Cloud

As people move workloads to shared and public cloud environments, what methods are available to attest their environment has not been tampered with? Is there a good way to use a standardized cryptographic module to do remote attestation, trusted system boot, and so on?

In this post we’ll introduce the Keylime project in some detail, and save a technology demo for a following hands-on article.

Keylime is an open source community-based project endeavoring to be the go-to technology for establishing and maintaining trusted infrastructure in distributed system deployments via two technologies: the use of embedded Trusted Platform Module (TPM) hardware (version 2 and later); and the Linux kernel subsystem – Integrity Measurement Architecture (IMA).

Building a Scalable TensorFlow Twitter Bot for Red Hat Summit

Posted on: June 4, 2019

Anand Sanmukhani, Red Hat

Red Hat’s AI Center of Excellence and PerceptiLabs wanted a way to demonstrate a TensorFlow model to the public during the 2019 Red Hat Summit. The plan was for this model to take images as input, and then respond with the likelihood of a Red Hat fedora being in that image. Here’s what we learned during Red Hat Summit.

This application, which we called Fedora Finder Bot, would be featured during Red Hat CTO Chris Wright’s keynote, where PerceptiLabs demoed their AI platform.

Our initial solution for this objective would be a Twitter bot that receives tweets or direct messages and replies with the output from the TensorFlow model. Twitter being a public service, we felt it could make the model available to a large number of users, so that any user could just tweet to the bot with a picture and the bot would respond with the model’s output.
