Cloud: Tiers and Instances
- Use your portal's Products tab to raise or modify a Free node, a Development node, or a Production cluster.
- Free and Development nodes, as well as Production "basic" grade clusters, are operated by burstable instances.
- The Production cluster grades Standard and Performance are Reserved clusters.

A Free Cloud Node
Free RavenDB cloud nodes are great for experiments and evaluation. They are equipped with the
most basic configuration and capabilities. They have a single node and no Service-Level Agreement (SLA).
You can run only one free node per account.
To raise a free cloud node, use the Products tab
to create a free-tier instance.
-
A free instance is identical to a development Dev10 instance.
It comes with a monthly credit of $10, used to cover the cost of the instance and incidentals like backup storage and traffic.
If your free instance uses more resources than the provided credit, you'll need to pay for these resources or stop your instance.
-
The free instance is limited to the community subset of features.
-
If you don't use your free instance for over 30 days, it will be terminated.
A Development Cloud Server
A development server is equipped with all of RavenDB's features, though it are not suitable for production because:
- Single-node configuration (no replication),
- Burstable CPU usage which is suitable for small to medium production loads.
Burstable instances can become throttled if usage excedes allocated resources. - Lack of backup procedure and
- No Service Level Agreement.
To raise a cloud Development server, create a product using the Products tab and choose the Development tier.
Select your server's configuration
Choose from the increasingly powerful configurations Dev10 to Dev70
Select your storage
Choose your storage type and size
In addition to the CPU / memory resources allocated to your instances, you can select the type of storage that will be assigned to your RavenDB instances. It is fairly obvious why the size of the storage matters, but it is important to also understand the impact of the storage type and allocated IOPS on the overall performance.
RavenDB, as a database, is sensitive to I/O latencies resulting from slow storage. If your instances are running into
high I/O latencies, RavenDB will alert you to the issue so you can upgrade the type of storage you are using and the
number of IOPS reserved for your instances.
A Production Cloud Cluster
The default production configuration is a three-node cluster, provisioned in separate
availability zones for maximum durability.
RavenDB Cloud also offers multi-region clusters to minimize local latency and clusters with a higher number of nodes to further distribute the cluster's workload.
Contact Support to provision customized cloud-based clusters with configurations that suit your needs.
The production tier offers three instance levels:
1. Basic
2. Standard
3. Performance
1. Basic-grade Production Cluster
Basic production clusters are burstable.
While suitable for low to medium workloads, they trade-off peak efficiency for lower costs.
Throttling
If burstable instances use more than their allocated budget, they can become throttled.
2. Standard-grade Production Cluster
The resources of standard production clusters are reserved.
The cluster can utilize them at all times, and is equipped to handle constant production load.
Use the slide-bars to choose your Standard Production cluster's configuration and storage.
In addition to the CPU / memory resources allocated to your instances, you can select the type of storage that will be assigned to your RavenDB instances. It is fairly obvious why the size of the storage matters, but it is important to also understand the impact of the storage type and allocated IOPS on the overall performance.
RavenDB, as a database, is sensitive to I/O latencies resulting from slow storage. If your instances are running into
high I/O latencies, RavenDB will alert you to the issue so you can upgrade the type of storage you are using and the
number of IOPS reserved for your instances.
3. Performance-grade Production Cluster
Performance cloud clusters are reserved, and we can custom-tailor them for your production environment needs so they include:
- High memory
- Reserved IO with NVMe drives
- Powerful processing
- Terabytes of storage space.
The Performance production tier is highly customizable.
Contact Support to modify your server configuration, the number of nodes in your cluster,
and various parameters of their deployment.
If you're interested in high global availability, for example, a multi-region deployment
can be easily set and would probably suit you better than the default arrangement.
