Scope and description of the service
Rahti is a cloud computing service that allows Users to host applications and make them accessible over the web. The Rahti service is based on OKD, which is a distribution of Kubernetes. The main features of Rahti are:
- Hosting of containerized applications
- Storage services
- Virtual networks for connecting container instances
- Load balancing of traffic to User Applications
- An application catalog with templates for ready-to-use common applications
- Features for replication, rolling updates, auto-recovery and auto-scaling of User Applications
- Basic default domain name and TLS for hosted User Applications (under rahtiapp.fi)
Users can manage their resources using a web interface accessible through a web browser and through a set of APIs which allow programmatic management of resources. In order to access and use the service the User must have a CSC user account.
The User's applications are isolated from other Users’ applications from a network, storage and computational view.
Service hours & exceptions
The service is designed to run continuously. However, the following exceptions apply:
- Planned service breaks - announced to Users at least three weeks in advance.
- Downtimes caused due to upgrades for fixing critical security issues are not considered SLA violations. In the case of critical security upgrades CSC reserves the right to apply the upgrades with minimal notice.
- Any other causes outside the service provider’s direct control.
Service components & dependencies
The Rahti service depends on the following services:
- Kajaani datacenter infrastructure
- Funet network
- The cPouta service

|Webpage and contact form||https://research.csc.fi/cloud-computing https://research.csc.fi/support|
|Response time target||Within three working days|
Disruptions to the agreed service functionality or quality will be handled according to an appropriate priority based on the impact and urgency of the incident. In this context, the following general priority guidelines apply:
- Ensuring normal levels of security
- Restoring normal service operation
- Restoring User Applications where possible
Response and resolution times are provided as Service level targets.
Fulfilment of service requests
In addition to resolving incidents, the following standard service requests are defined and will be fulfilled through the defined support channels:

Response and fulfilment times are provided as Service level targets.
Service level targets
The Rahti service level targets adhere to JHS 174 as follows:
|Service level targets|
|Service Level||A (basic)|
|Service time / incident handling||P1 Weekdays 8.00-16.00|
|Response||V1 reaction: 4h, solution: 2 BD|
Availability is calculated by subtracting the service break time from the ideal availability during service time. This information is obtained from internal monitoring systems and defined as Users’ ability to manage their User Applications, and the availability of the User Applications.
The normal functioning of the service is defined as:
- the ability to launch new User Applications.
- the availablility and integrity of the storage services.
- the functioning of the network, and the accessibility of User Applications.
- the functioning of replication, auto-recovery and auto-scaling of User Applications.
The Service Provider commits to inform the User if this SLA is violated or a violation is anticipated. For this, email as a communication channel will be used.
A User contacts the CSC Service Desk for the case of a possible SLA violation. The case will be analysed internally and, if the violation is confirmed, CSC will inform the User about the reasons for the violation, planned mitigation actions and expected resolution time.
Limitations and constraints
The provisioning of the service under the agreed service level targets is subject to the following limitations and constraints:
- Support is provided primarily in English and Finnish.
- A technical failure which affects individual Users does not count as downtime.
- Failures of single container instances is expected behaviour and do not count as downtime.
