infra:u Software as a Service (SaaS)
From German data centers
Cloud telephony,
mail, and S3 storage
Operating standard applications ties up unnecessary resources in many companies. The trend is clearly moving away from rigid, one-time purchases of complex software solutions and running your own hardware, toward flexible, ready-to-use solutions from the cloud.
With the infra:u Software as a Service (SaaS) solutions, UPONU complements its outsourcing offerings with a smart SaaS portfolio. We provide you with ready-made tools, from phone systems to secure groupware hosting to scalable S3 storage, all operated within the controlled environment of our German data centers, with a clear focus on data protection and resilience.

The ISDN phone network is history, and running your own on-premise phone system is no longer the most economical option either. Our cloud telephony replaces local systems and offers a software-based, virtual phone system that scales with your business.
Connecting devices is straightforward: whether an IP phone in the office, a softphone on a laptop, or an app on a smartphone, your employees are always reachable on their individual extension, regardless of location. Maintenance, updates, and the provisioning of new extensions are all handled centrally from the cloud.

Data such as backups, archives, or large media files grow exponentially. Classic file servers quickly reach their limits here. S3 object storage is the industry standard for handling large data volumes. Data isn't stored in classic folder structures but as "objects" (including metadata) in so-called "buckets".
Our S3-compatible storage gives you the established AWS interfaces for high interoperability with existing backup solutions, but with one key difference: your data isn't held by an international hyperscaler, but stored GDPR-compliant in our German data centers.
Email remains the central communication channel in the B2B environment. A mail server outage often means a complete standstill of business processes. Beyond this service, a wide range of additional services are needed today when it comes to collaboration. File storage, chat, video conferencing, and contact and calendar management are just some of the features users expect. With openDesk, we rely on a dependable open-source solution that is continuously developed further and offers open standards. We take over operation of your highly available groupware infrastructure. For you, that means no patching effort of your own and reliable availability without the administrative burden of running it yourself.
Predictable costs (OpEx)
You pay per user or storage volume instead of making large upfront investments in hardware and licenses (CapEx).
No infrastructure maintenance of your own
Disk failures, firmware updates, or changing technical requirements are no longer your concern.
Scalability
A new team member or growing storage needs can be accommodated with a single click.
Software as a Service transforms IT from a cost factor into an agile tool. The benefits are clear:
FAQ
Frequently asked questions
Especially for SMBs, avoiding the upfront cost of a hardware phone system makes good economic sense. You benefit from enterprise features (such as complex call routing or voicemail-to-email) and only pay for the extensions you actually need.
Yes, provided the provider processes communication data within the EU, operates servers in ISO-certified data centers, and provides a data processing agreement (DPA).
File storage stores data in a hierarchical folder structure. Block storage splits data into blocks (ideal for databases). Object storage stores data together with rich metadata in flat structures ("buckets"). It's excellent for huge, unstructured data volumes (archives, backups) since it scales practically without limit.
S3 storage offers mechanisms such as "Object Lock" (WORM, Write Once, Read Many). This means data, once written, cannot be modified or deleted for a defined period — a very effective protection against unauthorized encryption by ransomware.
