Decoupling microservices with Apache Camel and Debezium

Decoupling microservices with Apache Camel and Debezium

The rise of microservices-oriented architecture brought us new development paradigms and mantras about independent development and decoupling. In such a scenario, we have to deal with a situation where we aim for independence, but we still need to react to state changes in different enterprise domains.

I’ll use a simple and typical example in order to show what we’re talking about. Imagine the development of two independent microservices: Order and User. We designed them to expose a REST interface and to each use a separate database, as shown in Figure 1:

Diagram 1 - Order and User microservices

Figure 1: Order and User microservices.

How to secure microservices with Red Hat Single Sign-On, Fuse, and 3scale

How to secure microservices with Red Hat Single Sign-On, Fuse, and 3scale

In this article, we’ll cover microservice security concepts by using protocols such as OpenID Connect with the support of Red Hat Single Sign-On and 3scale. Working with a microservice-based architecture, user identity, and access control in a distributed, in-depth form must be carefully designed. Here, the integration of these tools will be detailed, step-by-step, in a realistic view.

This article exemplifies the use of tools that can securely run your businesses, avoiding using homemade solutions, and protecting your services by using an API gateway, preventing your applications from being exposed to the public network. The use of an API gateway also provides additional access control, monetization, and analytics.

Introduction to microservices observability with Eclipse MicroProfile

Introduction to microservices observability with Eclipse MicroProfile

Microservices provide a modern approach to development, which is compliant with the cloud environment and gives us the ability to create cloud-native applications. With microservices, we promote resilience, fault tolerance, and scale; however, a microservice approach also presents different challenges than monolithic applications because of its distributed nature.

One of these challenges involves monitoring and logging, which naturally brings us to the concept of observability. In this article, we’ll look at how Eclipse MicroProfile can help you implement observability in microservices.

Understanding Red Hat OpenShift’s Application Monitoring Operator

Understanding Red Hat OpenShift’s Application Monitoring Operator

Monitoring systems are usually composed of three layers: a database layer that hosts metrics data, a layer to display the stored metric data graphically in dashboards, and an alerting layer to send out notifications via methods such as email, on-call notification systems, and chat platforms. This article presents an overview of the components used in Red Hat OpenShift‘s Application Monitoring Operator, how to install them using the Operator, and an example of the Operator in action.
