The Hazelcast Serverless means that Hazelcast manages the cloud infrastructure for you. Each Viridian Serverless cluster is an independent deployment of the Hazelcast Platform in a Kubernetes container. This design guarantees resource isolation, prevents resource stealing and provides isolated network access. Viridian Serverless clusters come in two types:1) Development: Capped storage. You can store at most 1 GiB of data; and 2) Production: Uncapped storage. The cluster scales as you add or remove data. In this tutorial, you’ll learn how to connect a client to a cluster and use SQL to query data in the cluster.

Before You Begin

You need the following:

One of the most useful features of real-time stream processing is to combine the strengths and advantages of various technologies to provide a unique developer experience and an efficient way of processing data in real-time at scale. Hazelcast is a real-time distributed computation and storage platform for consistently low latency queries, aggregation, and stateful computation against real-time event streams and traditional data sources. Apache Pulsar is a real-time multitenant geo-replicated distributed pub-sub messaging and streaming platform for real-time workloads, handling millions of events per hour. 

However, real-time stream processing is not an easy task, especially when combining multiple live streams with large volumes of data stored in external data storages to provide context and instant results. When it comes to usage, Hazelcast can be used for the following things:
