In the last part of this series, we will explore how to use a Service Mesh for RBAC. For the implementation of the Service Mesh we are using the Open Source […]
Option: API Gateway Foto Source: Jeswin Thomas (www.pexels.com) In the last blog “OpenID Connect & Keycloak (part 5), we have described how a 3rd party component (Keycloak) can provide intermediary services for trust and security. Amongst others, keycloak takes care of the generation and configuration of the JWT token. The good thing: As all involved […]
Read this manual if you want to setup and demonstrate (or otherwise use) all the mechanisms of Quarkus GrumpyCat. First of all GrumpyCat is a micro services based multi player game, which you can use to demonstrate and play a nice PacMan / FatCat like game. But with this demo you can also easily demonstrate the benefits of using the GitOps principles for developing and deploying a bigger application.
As a computer scientist, I think the best thing about our job is clearly the need to keep up with the latest technological achievements. Depending on the specific area you work in, you can actually always be sure that the solutions to challenges are constantly changing. Kubernetes is no different in that regard. Let’s find […]
Overview What steps can we take to establish trust in our Software Supply Chain and ensure that our software can be traced back to its origin without introducing malicious code or dependencies? Moreover, how can we integrate Open Source tools to enhance the security of our Software Supply Chain’s lifecycle? As we explained in our […]
Foto Source: Ron Lach (www.pexels.com) Option: OpenID & Keycloak In the previous blog (part 4), we have introduced JSON Web Token to allow more transparent and convenient authentication and access management. In this blog (part 5), we will explore how we can extend the concept of a JWT to achieve even better standardization through oAuth2 […]
Foto Source: Nataliya Vaitkevich (www. pexels.com) Option: JWT In the previous blog part (part 3) we have used BasicAuthentication for transferring credentials which are then enforced in the requested service. This approach has several disadvantages. First and foremost, each service has access to user credentials. Thus, if one service is hacked, all services are impacted. […]
By Robert Baumgartner, Red Hat Austria, March 2023 (OpenShift 4.12, OpenShift distributed tracing data collection 0.63) In this blog, I will guide you on how to use OpenTelemetry with a Quarkus application; how to forward your OpenTelemetry information to Tempo and display it in Grafana UI. I will use distributed tracing to instrument my services […]
As ancient Greek philosopher Heraclitus once said, the only constant in life is change. And it accurately applies to language as well. The spectacle of language change can be observed from two perspectives: synchronous (different language versions going hand-in-hand at the same time) and asynchronous (how language evolves across decades, centuries or millennia). And, taking […]
Foto Source: CottonBro Studio (www.pexels.com) Option: BasicAuthentication In the previous post (Part 2), we have set the scene by implementing a basic service-to-service communication with 3 REST end-points (publicEP, userEP, adminEP). The checking of the role has been done programmatically against an HTTP query parameter. We have elaborated on the down-sides of this option and […]
