Using Docker + AWS to Build, Deploy and Scale your App

Brandon Klimek Articles, AWS, Cloud, DevOps, Docker, Python, Spring, Spring Boot, Tutorial 8 Comments

I recently worked to develop a software platform that relied on Spring Boot and Docker to prop up an API. Being the only developer on the project, I needed to find a way to quickly and efficiently deploy new releases. However, I found many solutions overwhelming to set up.

That was until I discovered AWS has tools that allow any developer to quickly build and deploy their application.

In this 30 minute tutorial, you will discover how to utilize the following technologies:
– AWS CodeCommit – source control (git)
– AWS Code Build – source code compiler, rest runner
– AWS Codepipeline – builds, tests, and deploys code every time the repo changes
-AWS Elastic Beanstalk – service to manage EC2 instances handling deployments, provisioning, load balancing, and health monitoring
-Docker + Spring Boot – Our containerized Spring Boot application for the demo

Once finished, you will have a Docker application running that automatically builds your software on commit, and deploys it to the Elastic beanstalk sitting behind a load balancer for scalability. This continuous integration pipeline will allow you to worry less about your deployments and get back to focusing on feature development within your application.

React NowPlaying Educational Application

We at Keyhole have been helping our clients adopt JavaScript-based single-page applications for over five years. We have been impressed with the adoption and advancement of the ever-changing JavaScript ecosystem.

React is a JavaScript technology that our teams enjoy working with. However, React differs from the other frameworks we’ve worked with in a handful of ways.

The best way to learn a new technology is to actually do something with it, as opposed to simply reading about it. So, we created a tangible React learning application to help our team get up-to-speed. The application repository has now been released publicly to help others learn.

Pull down the repo & try out React!

Angular State/Country Directive

A Lesson In ROI: Scratch vs. Adapt Existing Angular Code

On a recent client project, I needed to develop an Angular front-end for a form that included address information. As part of the address information, there were State and Country fields. I knew I needed to make these select lists, because from a UX perspective, it would be crazy to leave them as regular old text inputs. I knew I wanted to create directives to implement these select lists. I also knew I probably wasn’t the first developer to ever want to do this.

In this blog, I talk about a decision that all developers face every day: how to solve programming problems in the best way with the best use of time. The scenario we’ll talk about shows the use of Angular directives for creating select lists for country and state. In doing so, it provides a good understanding of Angular directives as one possible way they can help make Angular development great.

Converting Enterprise Applications to TypeScript

Clayton Terry Articles, Development Technologies & Tools, JavaScript, Single-Page Application, TypeScript Leave a Comment

We have all been there: some new technology comes out and we know it would improve our maintainability. But we can’t use it. We already picked a technology, it is already implemented, and we can’t change it now. We are stuck.

TypeScript does not work like that. TypeScript is JavaScript, and JavaScript is TypeScript. What this means is any existing files you have are compatible with any new file you add.

So why waste time changing if it’s all the same anyway? TypeScript has some great advantages that JavaScript does not. In this blog I will introduce some of those advantages, as well as some troubleshooting tips for if you run into issues when you choose to convert to TypeScript…

Using ELK In .NET Applications

Chase Aucoin .NET, Articles, Development Technologies & Tools, Microservices, moderntoolingseries 6 Comments

This article is part of a series of articles about modern tooling and techniques for building distributed systems in DotNet.

In our first article, we saw how easy it was to set up a full ELK stack by leveraging pre-built containers. In this blog, I show how to leverage ELK in a .NET application and aggregate our logs into a single place. You will see just how simple it is to start getting some insights into your application. Let’s get started…
