Fine-grained authorization for Quarkus microservices
Raffaele Spazzoli
Quarkus has support for Relationship-Based Access Control (ReBAC) to implement permissions robustly in microservices.
Container-native integration testing
Raffaele Spazzoli
It can be complex to set up an end-to-end integration test infrastructure, but the process can be simplified by using an infrastructure-as-code approach. In addition, running integration tests for multiple OS/browser combinations can waste resources and time, but a container orchestrator and ephemeral workloads can help mitigate that. This article shows how to build behavior-driven development (BDD) container-native integration tests and run them in OpenShift to overcome these obstacles.
Dynamically Creating Java Keystores in OpenShift

Introduction With a simple annotation to a service, you can dynamically create certificates in OpenShift. Certificates created this way are in PEM (base64-encoded certificates) format and cannot be directly consumed by Java applications, which need certificates to be stored in Java KeyStores . In this post, we are going to show a simple approach to enable Java applications to benefit from certificates dynamically created by OpenShift. Why certificates Certificates are part of a PKI infrastructure and can be used to...
An Incremental Path to Microservices
Raffaele Spazzoli
As a consultant for Red Hat, I have the privilege of seeing many customers. Some of them are working to find ways to split their applications in smaller chunks to implement the microservices architecture. I’m sure this trend is generalized even outside my own group of the customers. There is undoubtedly hype around microservices. Some organizations are moving toward microservices because it’s a trend, rather than to achieve a clear and measurable objective. In the process, these organizations are missing...
Architectural Cross-Cutting Concerns of Cloud Native Applications
Raffaele Spazzoli
Several organizations are wondering (and sometimes struggling on) how to port their current workloads to cloud environments. One of the main characteristics of a cloud environment is that the infrastructure is provisioned dynamically. This implies, for example, that we don’t know a priori where our resources are being allocated (we can find that out, though). VMs or containers will receive a dynamic IP. Storage will be allocated somewhere and attached to our VMs or containers and so on. So, how...
The fast-moving monolith: how we sped-up delivery from every three months, to every week
Raffaele Spazzoli
Editor's note: Raffaele Spazzoli is an Architect with Red Hat Consulting's PaaS and DevOps Practice. This blog post reflects his experience working for Key Bank prior to joining Red Hat. A recount of the journey from three-months, to one-week release cycle-time. This is the journey of KeyBank, a super-regional bank, from quarterly deployments to production to weekly deployments to production. In the process we adopted all open source software migrating from WebSphere to Tomcat and adopting OpenShift as our private...
