The trial period is available to businesses only as a means of testing and exploring the cloud infrastructure features. During the trial period, you can use Yandex Cloud resources with some restrictions.
Service Level Agreement (SLA)
The Service Level Agreement (SLA) does not apply to the trial period. We do not recommend running production applications in Yandex Cloud during the trial period.
Support
Technical support is provided in full during the trial period. For more information, see Requesting technical support.
Yandex Cloud Billing
Each cloud in Yandex Cloud must be linked to a single billing account. If you relink an existing cloud, you are effectively transferring it between billing accounts. For legal entities, you cannot relink a cloud and your DataSphere, Tracker, and DataLens services from a paid account to a trial period account.
Yandex Cloud Marketplace
During the trial period, no Yandex Cloud Marketplace paid products are available. However, once your paid consumption starts, you will be able to use the balance of your starting grant to pay for them.
Service quotas and limits
- Quotas
are organizational restrictions that can be changed by technical support. - Limits are technical limitations due to Yandex Cloud architectural features. You cannot change the limits.

Read and write operations utilize the same disk resource. The more read operations you do, the fewer write operations you can do, and vice versa. For more information, see Read and write operations.
4 To achieve maximum IOPS, we recommend performing read and write operations whose size is close to that of the disk block (4 KB by default).
5 To achieve the maximum possible bandwidth, we recommend performing 4 MB reads and writes.

Outgoing traffic filtering
Yandex Cloud automatically blocks traffic sent from Virtual Private Cloud public IPs to TCP port 25 of any servers on the internet and Yandex Compute Cloud VMs. The only exception is the traffic sent to Yandex Mail email servers, which is allowed and not blocked.
Yandex Cloud can provide a special public IP address with TCP port 25 opened upon request to the support team if you follow the Acceptable Use Policy
For public IPs that are already in use, port 25 cannot be opened.

Other restrictions
A single target group may only contain target resources from a single cloud network.
A target group can include resources that are connected to the same subnet within a single availability zone.
A resource will not be directly available on the target port if you add it to the internal load balancer's target group.
You can create a load balancer without a listener.
Health checks are transmitted from the 198.18.235.0/24
and 198.18.248.0/24
IP address ranges.
When connecting resources to the load balancer, keep in mind the limit on the maximum number of concurrent TCP/UDP connections per VM.
