Building a Spring Cloud Native Microservice Application on Azure, Part 1

Zach Gardner Articles, Azure, Cloud, Development Technologies & Tools, Java, Microservices, Spring Leave a Comment

The big three cloud providers (AWS, Azure, and Google Cloud, in that order) have their various strengths and areas of expertise. Most large organizations though typically pick one cloud provider for their cloud computing needs. This works well if you’re a Java shop that’s on AWS, or a Microsoft shop on Azure. But what if you’re on a large Java project in an organization that wants to use Azure? You’re in luck.

Microsoft Azure has come a long way, and is very supportive of non-Microsoft technologies. The proof though is in the pudding. Which is where this blog post comes in. I take Josh Long’s Bootiful Microservice Services, a great starting point to get a cloud native Spring microservice application up and running, and show how it can be run on Azure.

This first blog post will be all about setting up our basic microservices by walking through the various parts of Josh’s example application, with some best practices and patterns that I’ve found to be effective. Rather than a simplistic ToDo application, we’ll be basing our application off of my favorite bagel shop in New York, Original Bagel Boss in Hicksville, to manage its orders, inventory, etc. If we can run a bagel shop on a Spring application running on Azure, and keep customers happy and full of carbohydrates, then it proves out for applications of a similar size and complexity.

We’ll be staying mostly inside the familiar Java confines, then slowly start working our way out to getting our application deployed to Azure. Then we’ll start introducing additional complexity like Spring Batch jobs, a React front end, etc. A setup this complex will show that Azure is ready for prime time when it comes to running applications in production, even if they are built on non-Microsoft technologies…

Spring Boot and React: Happily Ever After

Matt McCandless Articles, Development Technologies & Tools, React, Spring, Spring Boot Leave a Comment

So you have mastered Spring Boot and started toying around with React. Now you want React to talk to your Boot app as your back-end API. That’s fabulous. You probably already know how to do this, but there is a kicker. You want to package them and start both of them as just one project.

Well, you’re in luck! This blog is going to take a couple of simple projects and combine them into one project. Lace up your boots and get ready to React!

Part 6: Node + Express for a ​S​imple ​S​ecurity ​M​odel

Part of the Solid Foundations Learning Series

This is an in-depth learning series focused on a specific application: a JavaScript-based suite of single-page applications optimized for use in a microservice environment. We focus on telling the story of “why” and “how” it was built.

Throughout this series, we have touched on adding navigation, content and single-page applications, but we haven’t touched on the security of the application yet.

In this article, we’re going to add a simple security model to the application which will accept a login, validate a user, redirect to a secure page, enable a logout, and catch any errors which occur during the process. Let’s get started.

Feature Addition: Mobile Push Notifications with AWS SNS

Keyhole consultant was engaged in an effort to implement a push notification solution for an existing mobile banking application.

To begin, Keyhole reviewed the application requirements to determine the best service to use moving forward. After the evaluation of Twilio and Amazon Web Services Simple Notification Service, the team concluded AWS SNS was the best solution.
