Debugging JVM Performance Issues at Okta
Our customers here at Okta expect a highly-available service that is always there when they need it. We’ve worked hard to design a service architecture that allows us to deploy code and do maintenance without disrupting our customers in any way. How do we achieve that? If we examine one slice of our core service, we have a reverse proxy set up in front of a fleet of Java application servers. When we need to...
Java + Spring Tutorials
Spring Boot, and the Spring framework in general, are the core tools for the modern Java developer. They abstract away many nuances of development and architecture, allowing you to focus on building your business logic, aka, the parts of your app that will move the needle for your organization. Here at Okta we believe in that abstraction, and that a big part of modern development is using the right tools to make the job not...
Java Microservices with Spring Cloud Config and JHipster
Developing a microservice architecture with Java and Spring Boot is quite popular these days. It’s definitely one of the most popular combinations in the Java ecosystem. If you need any proof, just look at all of the similar frameworks that have cropped up in the last few years: MicroProfile, Micronaut, and Quarkus, just to name a few. Spring Boot provided a much-needed spark to the Spring ecosystem when it was first released in 2014. Instead...
Java Microservices with Spring Boot and Spring Cloud
Java is a great language to use when developing a microservice architecture. In fact, some of the biggest names in our industry use it. Have you ever heard of Netflix, Amazon, or Google? What about eBay, Twitter, and LinkedIn? Yes, major companies handling incredible traffic are doing it with Java. Implementing a microservices architecture in Java isn’t for everyone. For that matter, implementing microservices, in general, isn’t often needed. Most companies do it to scale...
Use Schematics with Vue and Add Authentication in 5 Minutes
Schematics is a tool from the Angular team that allows you to manipulate projects with code. You can create files, update existing files, and add dependencies to any project that has a package.json file. That’s right, Schematics aren’t only for Angular projects! In this post, I’ll show you how to use Schematics to modify a project created with Vue CLI. Why Vue? Because it’s fast and efficient. Its default bundle size is smaller than Angular...
AWS Lambda vs Azure Functions for C# Serverless
As a C# developer, I became interested in how using a serverless function could complement existing projects I had done in ASP.NET 4.x. Enhancing ecosystems by using it for new requirements - without starting over from scratch - really had appeal. AWS Lambda came along first, with Azure Functions emerging onto the scene a couple of years later. In this post, we will briefly examine my experience getting started on both after using the .NET...
Angular Authentication with JWT
User registration and authentication are one of the features that almost no web application can do without. Authentication usually consists of a user entering using a username and a password and then being granted access to various resources or services. Authentication, by its very nature, relies on keeping the state of the user. This seems to contradict a fundamental property of HTTP, which is a stateless protocol. JSON Web Tokens (JWTs) provide one way to...
A Quick Guide to Spring Boot Login Options
In this post, you’re going to work through various options for implementing a login feature using Spring Boot 2.1. You’ll start with the most simple, basic auth, which you’d likely never want to use except for perhaps an internal backend tool, and move on to a simple form-based authentication page. Next, you’ll customize the default, auto-generated form by overriding some default templates and controllers. Finally, you’ll move on to adding Single Sign-on using OAuth 2.0....
Angular 8 + Spring Boot 2.2: Build a CRUD App Today!
If you’ve been a Java developer for more than 15 years, you probably remember when there were a plethora of Java web frameworks. It started with Struts and WebWork. Then Tapestry, Wicket, and JSF came along and championed the idea of component-based frameworks. Spring MVC was released in 2004 (in the same month as Flex 1.0 and JSF 1.0) and became the de-facto standard in Java web frameworks over the next six years. Then along...
Top 10 Visual Studio Code Extensions for Node.js
I am amazed at the adoption of Visual Studio Code by developers from all platforms and languages. According to the 2019 Stack Overflow Developer Survey, VS Code is dominating. The primary reasons I use VS Code are its great support for debugging JavaScript and Node.js code, and how easy it is to customize with free extensions available in Visual Studio Marketplace. However, there are thousands of extensions available! How do you know which ones are...
