Diary

Cloud Native Diary #1

The start of a new blog series. Every week, I'll share my journey working with application development, platform engineering, and cloud native.

Spring

Spring Native: Getting started with GraalVM native images

The Spring Native project provides support for packaging Spring applications as native images using GraalVM, with fast startup times and optimized memory usage.

Talks

Devoxx Ukraine 2020: "Cloud Native Spring - Migrating traditional apps" (Talk)

Learn the main steps for migrating traditional Spring applications to cloud native: embedded servers, Docker images, externalized configuration, disposability, logging and monitoring.

Spring

New Book: Cloud Native Spring in Action - With Spring Boot and Kubernetes

I’m thrilled to announce that my book is available in early access. Learn cloud native development with Spring Boot, Spring Cloud, Docker and Kubernetes.

Spring

Centralized Configuration with Spring Cloud Config

Learn how to build a central config server with Spring Cloud Config, configure a Spring Boot application with it, and refresh the config at runtime.

Keycloak

Spring Security and Keycloak to Secure a Spring Boot Application - A First Look

Keycloak is a solution for identity and access management. In this article, we're going to secure a Spring Boot application using Spring Security and Keycloak.

Quarkus

Quarkus - Develop Your First Supersonic Enterprise Java Application

In this article, we're going to getting started with our first supersonic Quarkus application. We will develop a RESTful application using the familiar JAX-RS and CDI APIs, learn how to run it in a Quarkus environment and see how to test it.

Jakarta EE

Getting Started With Jakarta EE - A Sample Application

Jakarta EE 8 has officially been released last Tuesday. It's the beginning of what it's been promised as "the Future of Cloud Native Java". Let's look at a sample application in Jakarta EE, using Wildfly, Gradle and Docker.

Keycloak

Keycloak Authentication Flows, SSO Protocols and Client Configuration

In this article, I'm going to introduce the concept of authentication flows. Then, I'll briefly mention the two protocols Keycloak can use to provide its services: OpenID Connect (on top of OAuth 2.0) and SAML. Finally, I'll show you how to configure Keycloak clients.

Blog

New Blog, New Platform, New Goal

Starting a blog is easy. Keep writing is not. This time, I'm confident it's going to be different. I'll be writing about security, Keycloak, Spring and software development on my brand new blog, just migrated from WordPress to Ghost.

Security

Access Control: Identification, Authentication, and Authorization

Unauthorized access to data and resources is one of the most significant and dangerous risks of the digital world. The OWASP Foundation, in their project about the Top 10 Application Security Risks - 2017, placed “Broken Authentication” as second, “Broken Access Control” as fifth.

Keycloak

Securing a Spring Boot Application with Keycloak - A First Look

Learn how to: set up a Spring Boot application for a public library, define the application resources, add access policies based on user roles. We're going to use OAuth 2.0 and OpenID Connect, specifically the standard Authorization Code Flow.

Keycloak

Keycloak Basic Configuration for Authentication and Authorization

Managing authentication and authorization is an essential task in every good-designed web application or service. Keycloak makes it very easy and practical, letting us focus on the application business logic rather than on the implementation of security features.

Keycloak

Introducing Keycloak for Identity and Access Management

This article is the first of a series where I'd like to introduce Keycloak as a solution to manage authentication and authorization, how to install it and which are the fundamental concepts and configurations.

Development

Highlights from HL7® FHIR® DevDays 2018 in Amsterdam

Last week I attended the HL7 FHIR DevDays 2018 in Amsterdam, the "most important and largest FHIR only event in the world" organised by Firely. It's been awesome: a lot of interesting and inspiring sessions, exciting projects and a vibrant and friendly community.

Spring

How to enable HTTPS in a Spring Boot Java application

Setting up HTTPS for Spring Boot requires two steps: getting an SSL certificate and configuring SSL in Spring Boot. Whether you're going to generate a self-signed certificate or you have already got one by a CA, I'll show you how to enable HTTPS in a Spring Boot application.

Spring

Spring Data JPA using Hibernate and Java Configuration with Annotations

Spring Data JPA makes it very easy to implement JPA-based repositories. In this tutorial, I’ll show you how to use it to integrate a relational database (PostgreSQL in my example) with a Spring Boot application.

Spring

Getting Started with Spring Data MongoDB using Java Configuration

In this tutorial, I'll show you how to use Spring Data MongoDB to integrate a MongoDB NoSQL database into a Spring Boot application. Spring lets you use either Java configuration or XML configuration or a mix of the two. I'll use a pure Java configuration.
