If you have any particular feature requests or enhancement ideas that you would like to see, please [get in touch with us](/contact-us/). Major announcements ------------------- ### ClickHouse® [Instaclustr for ClickHouse® on Azure is now generally available](https://www.instaclustr.com/blog/instaclustr-for-clickhouse-on-azure-is-now-generally-available/) We’re excited to announce that Instaclustr for ClickHouse® continued its momentum after [GA in November 2024 on AWS](https://www.instaclustr.com/blog/clickhouse-is-now-ga/), and is now fully available on Microsoft Azure. Customers can now enjoy lightning-fast queries, robust compression, and advanced new features while leveraging their existing Azure credits and billing arrangements through integration with the Azure Marketplace. ### Apache Kafka® [Automated migrating Apache Kafka clusters from ZooKeeper to KRaft](https://www.instaclustr.com/blog/migrating-apache-kafka-clusters-from-zookeeper-to-kraft/) Apache Kafka has made a significant architectural shift with the introduction of Kafka Raft ([KRaft](https://www.instaclustr.com/support/documentation/kafka/useful-concepts/apache-kafka-kraft-useful-information/)) mode, eliminating the dependency on Apache ZooKeeper for metadata management. ZooKeeper has been deprecated since Kafka 3.5.0 and has been removed in [version 4.0](https://www.instaclustr.com/blog/instaclustr-for-apache-kafka-and-kafka-connect-4-0-are-generally-available/), replaced by [KRaft](https://www.instaclustr.com/support/documentation/kafka/useful-concepts/apache-kafka-kraft-useful-information/) mode. KRaft enables Kafka nodes to self-manage metadata and leader elections, resulting in improved performance, scalability, and lower latency—making migration essential. Unlike manual migration, which is often error-prone and disruptive, NetApp Instaclustr’s automated migration process simplifies the transition, minimizing risk and downtime. Migrate now to keep your streaming platform robust, compatible, and focused on maximizing Kafka’s capabilities. ### Instaclustr Managed Platform [Stay in control: New notifications with the NetApp Instaclustr Maintenance Event System](https://www.instaclustr.com/blog/stay-in-control-new-notifications-with-the-netapp-instaclustr-maintenance-event-system/) NetApp now offers Customer Configurable Notification Preferences and Slack webhook integration for the Instaclustr Maintenance Events System. Customers can choose to receive cluster maintenance notifications via email or Slack, tailored per account. This flexible system enhances visibility and control over maintenance communications for all Instaclustr Managed Platform, ensuring targeted, meaningful, and timely updates at no additional cost. [Public Preview release of Zero Inbound Access](https://www.instaclustr.com/support/documentation/announcements/general/instaclustr-releases-zero-inbound-access-public-preview/) Zero Inbound Access clusters provide our most secure management connectivity option, removing the requirement to expose any components directly to the internet. Unlike Private Network clusters, or Public Network clusters, Zero Inbound Access eliminates the requirement for any routable public IP addresses in the customer deployment—including the bastion or gateway instance. Other significant changes ------------------------- ### Apache Cassandra® - Released [Apache Cassandra 4.1.9](https://www.instaclustr.com/support/documentation/useful-information/lifecycle-status-of-application-versions/#section-cassandra-cassandra) into General Availability on the NetApp Instaclustr Managed Platform. - Support for i4g node sizes and the new r7g and r8g families of EBS throughput and IOPS optimized instances for Apache Cassandra has been added to the platform. - The default `network_authorizer` for all Apache Cassandra 4+ clusters on the Instaclustr platform has been changed to `CassandraNetworkAuthorizer`, enabling users to restrict access to specific data centers. - Cassandra 3 End of Life has been announced for November 30, 2025, on the NetApp Instaclustr Platform.
