In the blog post we look into the unless property of the @Cacheable Spring annotation when using a custom key generator.

In this blogpost we are showing how to deploy a Spring Boot application to OpenShift levaraging the fabric8-maven-plugin and Spring Cloud Kubernetes

Many modern microservice architectures use a service discovery tool, like Eureka, that enable a client service to make requests to a dynamically changing set of service instances. Often these client services need a caching solution when the downstream services are not responding fast enough. Hazelcast is a popular distributed caching solution and with the Hazelcast Eureka plugin is possible to dynamically configure the nodes leveraging Eureka.

In this blog post we look into how to setup the development environment when deploying to a Kubernetes cluster. We will use a simple Spring Boot service which we deploy to a local Kubernetes cluster (using Minikube) and also to a remote Kubernetes cluster (using GKE).

In this blog I describe how you can run easily a multi-node Elasticsearch cluster with security enabled and access it with Kibana.

Note, that this setup is not for production. It is recommended to run only one node of Elasticsearch per server, but this setup is very useful for a development environment testing failover and different configurations.

When having a microservices environment we must think of the resiliency of our environment when platform services like config-service, discovery-service are not available for a short period of time. Let’s consider a customer-service which uses discovery first bootstrap registering with a discovery-service and getting external configuration from the config-service. What we want is to be able to start the services in any order.
