Spring Boot is a framework that helps to build microservices easily. In the Java ecosystem, it’s one of the most preferred ways of building microservices as of now. In a microservice architecture, there are different options to share data among the running services: one of them is caching, which Spring Boot leverages. It also provides […]
As we have announced earlier, Jet 4.0 is out! In this blog post, we aim to give you the lower-level details needed for migrating from older versions. Jet 4.0 is a major version release. According to the semantic versioning, we apply, this means that in version 4.0 some of the API has changed in a […]
In the first blog post, I explained the Blue/Green Deployments feature of Hazelcast IMDG Enterprise in general. Now, it is time to go through the top 5 scenarios where you can benefit this feature from. When using these features, it may be necessary to copy data or synchronize data from one cluster to the other. […]
Cert-Manager became a standard way for issuing and rotating certificates in Kubernetes and OpenShift environments. Simple to install. Simple to use. Well integrated with Vault and other secret managers. No surprise it’s the way to go if you want to set up secure communication between your applications! In this blog post, I show how to […]
This is the first blog post for Hazelcast IMDG’s Blue/Green Deployments feature, which is the most recent member of the Enterprise edition. “Blue/Green deployment” refers to a software technique used to reduce or even eliminate system downtime and the associated business risk by deploying two mirrored production environments referred to as “Blue” and “Green”.

Virtual meetups with Hazelcast covering data streaming and in-memory computing topics.
Hazelcast Cloud Enterprise is the new cloud-native managed service that allows you to quickly set up a cluster of Hazelcast IMDG nodes in a public cloud (Amazon Web Services today, with Google GCP and Microsoft Azure coming later this year), and have that cluster fully managed for you by Hazelcast. Setting up the cluster requires […]
Today is PI DAY! Obviously, Pi has rather more than 2 decimal places. To have some fun, let’s use Jet to drive multiple Python workers to calculate Pi with increasing accuracy. A tiny bit of mathematics Pi is the ratio of a circle’s radius to its circumference. It’s 3.14. It’s 3.1416. It’s 3.14159266 or whatever. It […]
Machine learning projects can be split into two phases: Training Inference During the training phase, data science teams have to obtain, analyze and understand available data and generalize it into a mathematical model. The model uses the features of the sample data to reason about data it has never seen. Although it can be completely […]
