The Keyhole team is excited to share an internal educational video that is now available to the public. In our first-ever video release, we discuss microservices platform orchestration from a broad scope.

Specifically, Principal Consultant Jaime Niswonger takes a technology-agnostic look at the โ€œbig ideasโ€ integral to platform orchestration for the enterprise. He introduces three popular orchestration platforms, Kubernetes, OpenShift, and Cloud Foundry, and discusses scaling container deployments in the enterprise. The video is 60 minutes in duration.

Go On The Fly

Go “On The Fly”

David Pitt Articles, Development Technologies & Tools, Keyhole Creations, Programming, Tutorial Leave a Comment

People that know me, know that I love to fly fish and tie flies. I made up the saying โ€œTime flies when youโ€™re tying flies.โ€ It is true, just like when you are trying to solve a programming problem, time flies.

Over the past few years, we at Keyhole have utilized Docker (with assorted technologies) and have gotten up to speed on the Hyperledger blockchain framework. Something that all of these technologies have in common is the Go language. Go is the language used to implement Docker, Hyperledger, OpenShift, and many other system-level applications.

Personally, I like to peek under the hood to better understand the tools Iโ€™m using. That led me to learning about the Go language. And in my opinion, the best way to learn a language is to build something.

So, I built an application for fly tying videos. There are numerous fly tying tutorials on YouTube, so I built an application that allows them to be organized into virtual fly boxes and types.

In this blog, I will introduce you to the Go language. Weโ€™ll go over some of the key language concepts by walking through how the https://flytyerworld.com server-side API is implemented using Go.

Integrating Azure Functions with Cosmos DB SQL API in .NET Core 2.2

Zach Gardner .NET Core, API Development, Articles, Azure, Cloud, Development Technologies & Tools, SQL, Tutorial Leave a Comment

I am working on a project that leverages both Azure Functions as well as Cosmos DB. In trying to get both of these components wired together, I found that there are very few examples that work with the most recent versions of these components. I also saw examples that could work at a small scale, but donโ€™t show industry-standard best practices, and would lead to performance issues if deployed in an environment with any meaningful traffic.

To that end, I put together this blog post showing how to set up an Azure Functions project in .NET Core 2.2 to integrate with Cosmos DBโ€™s SQL API using its native tooling.

Machine Learning: The Time is Now!

David Pitt Articles, Machine Learning, React, Tutorial Leave a Comment

Machine Learning enables a system to automatically learn and progress from experience without being explicitly programmed. Itโ€™s a subset of the artificial intelligence (AI) technology space being applied and used throughout your everyday life. Think Siri, Alexa, toll booth scanners, text transcription of voicemails – these types of tools are used by just about everyone.

Image recognition and computer vision are also widely being used in production; recently just heard that Los Angeles, CA has made it illegal for law enforcement to use face recognition technology in its numerous public video cameras. The current state of the art allows real-time identification.

Interestingly, the algorithms and know-how for Machine Learning have been around for a long time. Artificial Intelligence was coined and researched as far back as the late 1950s, the advent of the digital computer, and expert systems and neural networks, that theoretically mimics how our brain learns.

The increase in Machine Learning production-ready applications started around 2012, with increased processing, bandwidth, and internet throughput power. This is important as deep learning algorithms like Neural Networks require lots of data and FPUs/GPUs to train.

In this blog, we introduce a conceptual overview of Neural Networks with a simple Neural Net code example implementation using Go. We will interact with it by building a ReactJS interface and train the Neural Network to recognize hand-drawn images of the numbers 0-9. Letโ€™s dive in….

AWS Amplify GraphQL Queries with TypeScript and Hooks

Mat Warger API Development, Articles, AWS, Cloud, GraphQL, JavaScript, React, Tutorial, TypeScript 1 Comment

I’m a big fan of Amplify. I’m also a big fan of TypeScript. Amplify is not built with TypeScript, and to use it effectively, sometimes you need to give it a little help, especially when it comes to GraphQL. With the advent of hooks, we can create some nice utilities for ourselves that let us leverage the power of TypeScript with our GraphQL queries. Let’s see what that looks like.

I’ll be assuming familiarity with React and TypeScript, i…
