Atlas Infinite and its documentation might change at any time during the Preview period. To learn more, see [Preview Features](https://www.mongodb.com/docs/preview-features/). Atlas Infinite is a MongoDB Atlas edition, built on an architecture that separates compute from storage into independent layers, designed for mission-critical high-performance use cases, with built-in security controls. This design delivers high performance, scalability, and elasticity. You can scale compute and storage independently and rapidly, recover quickly from failures, and simplify operational workflows. To learn how this documentation is organized across editions, see [About This Documentation.](https://www.mongodb.com/docs/atlas/infinite/atlas-infinite-landing.md#std-label-atlas-infinite-about-docs) ## Architecture The following diagram shows how Atlas Infinite separates compute from storage. ![Diagram showing Atlas Infinite compute nodes, a primary and a standby, connecting to a separate Atlas-managed storage layer.](/images/infinite/atlas-infinite-storage-overview.svg) In Atlas Infinite, compute and storage are separate layers. Your application's queries, transactions, and aggregations run on compute nodes. MongoDB manages the storage layer independently of the compute layer, so operations such as scaling the cluster tier, adding read-only nodes, and recovering from a node failure run without moving or replicating data. Your application connects to your Atlas Infinite cluster using MongoDB drivers and other connection methods. You can also access and manage the cluster with MongoDB programmatic tools. To learn more about the architecture, see [MongoDB Atlas Infinite: Architecture.](https://www.mongodb.com/docs/atlas/infinite/atlas-infinite-architecture.md#std-label-atlas-infinite-architecture) ## Benefits By separating compute from storage, Atlas Infinite lets you: - **Scale independently**: You scale the cluster tier and storage capacity independently, so scaling the cluster tier doesn't require scaling storage capacity. - **Scale quickly**: Scaling Atlas Infinite vertically and horizontally is quick, so you don't have to preprovision for peaks or preplan scaling in anticipation of events. - **Simplify operations**: In Atlas Infinite, you can increase storage capacity without downtime. - **Maximize throughput and performance**: Atlas Infinite runs backup, restore, and point-in-time recovery at the storage layer, independently of the compute layer. This offloads that work from the compute layer, leaving more capacity to serve your application's workload. ### Performance The Atlas Infinite architecture is optimized for performance. Many workloads achieve high throughput on Atlas Infinite. Performance depends on the workload, so test with your own workload to measure the impact. ### Elasticity Atlas Infinite scales compute and storage independently, so you can add compute capacity for a workload spike without changing storage. Atlas Infinite supports [auto-scaling for the cluster tier](https://www.mongodb.com/docs/atlas/cluster-autoscaling-compute-infinite.md#std-label-cluster-autoscaling-compute-infinite), and scales up and down in reaction to changes in demand. You can scale horizontally by [adding read-only nodes](https://www.mongodb.com/docs/atlas/cluster-config/multi-cloud-distribution.md#std-label-atlas-infinite-workload-isolation), which read from the storage layer and start serving reads in minutes. ### Scalability Atlas Infinite scales storage independently of compute, so you can increase storage capacity to support growing, enterprise-level applications without scaling the cluster tier. In Atlas Infinite, you scale your cluster vertically by increasing the cluster tier. A larger tier provides more storage throughput and storage IOPS. When you scale your cluster vertically, Atlas Infinite doesn't move your data. When you add read-only nodes to an Atlas Infinite cluster, they read from the storage layer and start serving reads in minutes, without an initial sync. ## Security Atlas Infinite is designed to be secure. It always encrypts your data before it leaves the compute node, so the storage layer cannot read your application's data. Encryption is mandatory, and Atlas Infinite supports customer-managed data encryption keys (CMK/BYOK). Atlas Infinite supports the following security controls: - [PrivateLink](https://www.mongodb.com/docs/atlas/security-configure-private-endpoints.md#std-label-private-endpoint) - [IP access lists](https://www.mongodb.com/docs/atlas/security/ip-access-list.md#std-label-access-list) - [IAM and single sign-on (SSO)](https://www.mongodb.com/docs/atlas/security/federated-authentication.md#std-label-atlas-federated-authentication) - [Auditing](https://www.mongodb.com/docs/atlas/database-auditing.md#std-label-set-up-database-auditing) - [Field-level encryption (FLE)](https://www.mongodb.com/docs/manual/core/csfle.md#std-label-manual-csfle-feature) - [Network peering](https://www.mongodb.com/docs/atlas/security-vpc-peering.md#std-label-vpc-peering) To learn how Atlas encrypts your data at rest and which security controls apply, see [Encryption at Rest on Atlas Infinite.](https://www.mongodb.com/docs/atlas/security-encryption-at-rest-overview.md#std-label-atlas-infinite-encryption-at-rest) ## Resilience and Recovery In Atlas Infinite, the storage layer keeps your data durable. MongoDB doesn't rely on the compute nodes for the durability of your data. An Atlas Infinite cluster has two electable compute nodes, a primary and a standby. Together they form a highly available shard (HA shard), a unit specific to Atlas Infinite and distinct from a MongoDB [shard](https://www.mongodb.com/docs/manual/reference/glossary.md#std-term-shard). If the primary fails or restarts, the standby becomes the primary. The storage layer coordinates the failover from the primary to the standby instead of an election among the cluster's nodes and keeps your recent data readily available. Backup, restore, and point-in-time recovery run at the storage layer. To learn how replication and failover work on an Atlas Infinite cluster, see [Replication and Failover](https://www.mongodb.com/docs/atlas/infinite/atlas-infinite-architecture.md#std-label-atlas-infinite-replication). To learn about backup and restore, see [Restore an Atlas Infinite Cluster.](https://www.mongodb.com/docs/atlas/backup/cloud-backup/atlas-infinite-restore.md#std-label-atlas-infinite-backup) ## Operational Experience Your application runs on Atlas Infinite without code changes. Atlas Infinite uses the MongoDB wire protocol and supports the full MongoDB query API, including queries, aggregations, indexes, and transactions. Atlas Infinite also works with the following tools: - `mongosh` - Compass - [Atlas Administration API](https://www.mongodb.com/docs/atlas/api/atlas-admin-api.md#std-label-atlas-admin-api), with some endpoints specific to Atlas Infinite - Atlas CLI, with some commands specific to Atlas Infinite - [Terraform Provider](https://www.mongodb.com/docs/atlas/terraform.md#std-label-getting-started-terraform), with some attributes specific to Atlas Infinite - [SQL Interface](https://www.mongodb.com/docs/sql-interface.md#std-label-connect-with-sql-overview), enabled directly on the cluster On an Atlas Infinite cluster, you can enable the SQL Interface directly on the cluster rather than through a federated database instance. Atlas provides alerts specific to Atlas Infinite. ## Public Preview Availability ### Supported in Public Preview Atlas Infinite supports the following features in public preview: - **The complete MongoDB database semantics and features**: For the duration of public preview, Atlas Infinite clusters run the latest MongoDB 9.x version, using the Latest Version With Auto Upgrades release option in the Atlas UI.

To compare the two editions in detail, see [MongoDB Atlas Database Editions.](https://www.mongodb.com/docs/atlas/database-editions.md#std-label-atlas-editions) ## About This Documentation Most Atlas documentation applies to both Atlas Core and Atlas Infinite, because the Atlas interface, drivers, APIs, and most operational workflows are the same across editions. Documentation describes which editions each page or section applies to, as follows: - **Applies to both editions**: Unless a page says otherwise, its content applies to both Atlas Core and Atlas Infinite. - **Applies to one edition only**: When content applies to a single edition, the page identifies that edition in its title or text. - **Not supported on Atlas Infinite**: When a feature isn't available on Atlas Infinite during public preview, the page includes a note and links to the supported features. - **Behaves differently on Atlas Infinite**: When a workflow or option differs between editions, the page or section calls out the difference in place. This page is the starting point for Atlas Infinite. To find information about a specific feature, go to the Atlas topic for that feature and look for Atlas Infinite callouts. ## Take the Next Steps - [Compare the database editions](https://www.mongodb.com/docs/atlas/database-editions.md#std-label-atlas-editions) - [Understand the Atlas Infinite architecture](https://www.mongodb.com/docs/atlas/infinite/atlas-infinite-architecture.md#std-label-atlas-infinite-architecture) - [Review Atlas Infinite public preview limitations](https://www.mongodb.com/docs/atlas/infinite/atlas-infinite-landing.md#std-label-atlas-infinite-availability) - [Review encryption and security controls](https://www.mongodb.com/docs/atlas/security-encryption-at-rest-overview.md#std-label-atlas-encryption-at-rest-overview) - [Create an Atlas Infinite cluster](https://www.mongodb.com/docs/atlas/tutorial/create-new-cluster.md#std-label-create-new-cluster) - [Load data into an Atlas Infinite cluster](https://www.mongodb.com/docs/atlas/import/atlas-infinite-load-data.md#std-label-atlas-infinite-load-data) - [Manage an Atlas Infinite cluster](https://www.mongodb.com/docs/atlas/manage-clusters.md#std-label-manage-clusters) - [Modify an Atlas Infinite cluster](https://www.mongodb.com/docs/atlas/infinite/atlas-infinite-modify-cluster.md#std-label-atlas-infinite-modify-cluster) - [Manage Atlas Infinite cluster storage](https://www.mongodb.com/docs/atlas/infinite/atlas-infinite-storage.md#std-label-atlas-infinite-storage) - [Monitor Atlas Infinite cluster metrics](https://www.mongodb.com/docs/atlas/review-available-metrics.md#std-label-atlas-infinite-metrics) - [Back up and restore an Atlas Infinite cluster](https://www.mongodb.com/docs/atlas/backup/cloud-backup/atlas-infinite-restore.md#std-label-atlas-infinite-backup) - [Stop, start, and delete an Atlas Infinite cluster](https://www.mongodb.com/docs/atlas/pause-terminate-cluster.md#std-label-pause-terminate-cluster) - [Review Atlas Infinite billing](https://www.mongodb.com/docs/atlas/billing/atlas-infinite-costs.md#std-label-atlas-infinite-billing)
