Scalable File Service (SFS)

When working on projects, you may face the situation that you need data to be accessed by multiple servers or services. Or, when using a container engine like the Open Telekom Cloud Cloud Container Engine (CCE), a persistent storage service or data storage for multiple containers may be required.

The Scalable File Service (SFS) is the perfect fit for these demands. SFS combines the the scalability of Object Storage Service (OBS) with the performance of Elastic Volume Storage (EVS) while providing the convenience of data availability for all network participants via NFSv3 protocol. The SFS File storage is available in multiple types depending on your preference. Higher performance file-types with high Input/Output operations suits handling of large amount of files with a small size while lower performance types may fit to larger file-sizes and smaller amount of files. SFS is made available within a high-availability cluster within a single-AZ. We highly recommend to even protect the data via the Cloud Backup & Recovery (CBR) service. This service stores your backup data on the Object Storage Service, meaning that it is automatically replicated to multiple Open Telekom Cloud availability zones (AZs), protecting it against AZ outages.

Scalable File Service in the Open Telekom Cloud

Reasons for SFS in the Open Telekom Cloud

Compliant

SFS data is stored in the Deutsche Telekom's data centers. These run in Europe and comply with General Data Protection Regulation (GDPR) requirements. This ensures that any service built on top of the Open Telekom Cloud also easily and heedlessly complies to the GDPR.

Reliable & durable

The SFS runs in a high-availability cluster within a permanently monitored availability zone (AZ) and offers an availability of up to 99.95% and a durability of up to 99.9999999% (9 nines). The backup functionality provides additional security as the CBR service creates and stores backups of your file storage redundantly in all 3 availability zones of your Open Telekom Cloud region

Fast & secure

SFS is a high-performance storage system with high IOPS, low latency, and high bandwidth suitable for High Performance Computing. It supports up to 1,000,000 IOPS, provides a latency within 1-3 ms and provides a max bandwidth of up to 20 GB/s. In addition, all your data stored on SFS can conveniently be encrypted via the Key Management Service (KMS) of the Open Telekom Cloud.

Key Features of SFS

Fully managed file service

Scalable file service is a fully managed file storage service that can be accessed via NFSv3. You can access files across your Elastic Cloud Servers (ECS), Bare Metal Servers (BMS) or containers from the Cloud Container Engine (CCE). Simply create a file share via the Open Telekom Cloud console or the API.

Backup of SFS Turbo

SFS runs in a high availability cluster within your selected AZ. You can make use of the SFS Turbo backup functionality provided via CBR to extend your data protection. The creation of backup policies ensures that your backups are executed automatically and that they are retained in the system as long as you need them. In addition, new file system can be made based on created backups.

Encryption

The Scalable File Service provides an encryption functionality that automatically encrypts the data on your created file systems. The encryption service is provided via the KMS using the industry standard XTS-AES-256 encryption algorithm.

Monitoring

Monitor the performance of your SFS shares via the Cloud Eye Service. This allows you to monitor key performance indicators like read or write bandwidth.

Structure and Function

Use Cases

File Sharing

Thanks to a high IOPS, high bandwidth and low latency, the SFS service can be used for any kind of file sharing demands. Companies with a larger number of departments and employees can simply use the SFS company-wide for data & document creation, editing & sharing.

High Performance Computing

High performance computing executes computationally intensive operations on multiple resources. For an efficient execution, the data storage solution needs to ensure that the desired performance does not become the bottleneck. Thanks to the high IOPS, low latency, and high bandwidth, SFS is the ideal solution for high performance computing demands.

Data sharing for distributed applications

More and more development teams are creating applications using modern container technologies. SFS can be the persistent storage for your cloud container or data share across multiple containers, enabling you to create distributed applications. The Scalable File Service is therefore a good solution to provide a common storage system for your development teams.

Content management and web services

The Scalable File Service can be the data source for your scaling content management services as well as web services. It allows you to quickly publish content like documents, videos or other files through your services by utilizing the SFS share as a backend storage solution.
