- ClickHouse Cloud now offers a simplified purchasing experience through AWS Marketplace, with separate options for [pay-as-you-go](https://aws.amazon.com/marketplace/pp/prodview-p4gwofrqpkltu?sr=0-2&ref_=beagle&applicationId=AWSMPContessa) and [committed spend contracts](https://aws.amazon.com/marketplace/pp/prodview-4qyeihstyym2s?sr=0-3&ref_=beagle&applicationId=AWSMPContessa).

- **Service Monitoring - Resource Utilization Dashboard**  
  The CPU utilization and memory utilization metrics display will change to show the maximum utilization metric during a particular time period to better surface instances of underprovisionment, from average.
  In addition, the CPU utilization metric will show a kubernetes-level CPU utilization metric which more closely resembles the metric used by ClickHouse Cloud’s autoscaler.
- **External Buckets**  
  ClickHouse Cloud now lets you export backups directly to your own cloud service provider account.
  Connect your external storage bucket - AWS S3, Google Cloud Storage, or Azure Blob Storage - and take control of your backup management.

- [ClickHouse Cloud Azure Private Link](/docs/cloud/security/azure-privatelink) has switched from using Resource GUID to Resource ID filters for resource identification. You can still use the legacy Resource GUID, which is backward compatible, but we recommend switching to Resource ID filters. For migration details see the [docs](/docs/cloud/security/azure-privatelink#obtaining-private-endpoint-resourceid) for Azure Private Link.

- **ClickHouse Connector for AWS Glue**  
  You can now use the official [ClickHouse Connector for AWS Glue](/docs/integrations/glue) that is available from the [AWS Marketplace](https://aws.amazon.com/marketplace/pp/prodview-eqvmuopqzdg7s). Utilizes AWS Glue’s Apache
  Spark-based serverless engine for extracting, transforming and loading data integration between ClickHouse and other data sources. Get
  started by following along with the announcement [blogpost](http://clickhouse.com/blog/clickhouse-connector-aws-glue) for how to create tables, write and read data between ClickHouse and Spark.
- **Change to the minimum number of replicas in a service**  
  Services which have been scaled up can now be [scaled back down](/docs/manage/scaling) to use a single replica (previously the minimum was 2 replicas). Note: single replica services have reduced availability and are not recommended for production usage.
- ClickHouse Cloud will begin to send notifications related to service scaling and service version upgrades, by default for administrator roles. You can adjust their notification preferences in their notification settings.

- **ClickPipes for MongoDB CDC now in Private Preview**
  You can now use ClickPipes to replicate data from MongoDB into ClickHouse Cloud in a few clicks, enabling
  real-time analytics without the need for external ETL tools. The connector supports continuous
  replication as well as one-time migrations, and is compatible with MongoDB Atlas and self-hosted MongoDB
  deployments. Read the [blogpost](https://clickhouse.com/blog/mongodb-cdc-clickhouse-preview) for an overview of the MongoDB CDC connector and [sign up for early access here](https://clickhouse.com/cloud/clickpipes/mongodb-cdc-connector)!

  - [Bug fix] Object storage ClickPipes writing to a destination table using the Null engine now report "Total records" and "Data ingested" metrics in the UI.
  - [Bug fix] The “Time period” selector for metrics in the UI defaulted to “24 hours” regardless of the selected time period. This has now been fixed, and the UI correctly updates the charts for the selected time period.
- **Cross-region private link (AWS)** is now Generally Available. Please refer to the [documentation](/docs/manage/security/aws-privatelink) for the list of supported regions.
