PaaS: Definition, benefits and use cases for businesses

Cloud technologies have long since become the backbone of digital business models. Especially for companies developing software applications or operating IoT platforms, Platform as a Service (PaaS) opens up completely new possibilities. But what exactly does the term mean? How does PaaS differ from SaaS? And what should companies consider when choosing a PaaS provider?

The abbreviation PaaS stands for Platform as a Service. It refers to a cloud service model that provides businesses with a ready-to-use platform for developing, deploying and scaling software applications. The major advantage: the entire infrastructure – from the server and operating system to databases and development tools – is provided by the vendor. This allows companies to focus entirely on programming and operating their applications, without having to maintain their own hardware or middleware. It is an ideal starting point for agile teams, complex projects or IoT applications with high scalability requirements.

PaaS is aimed at companies that want to develop and operate their own software applications. The platform provides all the necessary tools, including PaaS servers, development environments, databases and automation tools.

Software as a Service (SaaS), on the other hand, delivers ready-made software solutions that can be used directly and without any development. Examples include email programmes, CRM systems or accounting software.

Many companies today deliberately opt for a mix of PaaS and SaaS to benefit from the advantages of both models. While they cover standard processes using SaaS solutions, PaaS enables them to develop customised applications – for example for real-time evaluation of sensor data or the integration of specific IoT devices.

• Faster development cycles: Pre-configured development environments and automated processes significantly reduce time to market.
• Less effort for infrastructure: Server, network and storage are managed by the provider. Companies can focus on what matters: their application.
• Scalability at the push of a button: Whether start-up or corporation – PaaS dynamically scales with the requirements.
• Seamless integration into IoT environments: Many platforms offer interfaces for IoT devices, data streaming or edge computing.
• Cost control through pay-per-use: You only pay for what you actually use – ideal for agile projects or MVP tests.

• Vendor lock-in: Switching to another platform can be complex and costly, especially with proprietary technologies.
• Less control over infrastructure: Configuration, hosting locations and security mechanisms are not fully in the company’s hands.
• Security and compliance risks: Especially in regulated industries, aspects such as data protection, encryption and access management must be carefully examined.
• Limited customisation with some platforms: Depending on the provider, platform use may be restricted by technical requirements.

In industrial environments, logistics or smart city applications, the number of connected devices is growing rapidly. As a result, so are the demands on processing large volumes of data, automated control and the development of customised applications. This is precisely where Platform as a Service comes in – as a central component in the IoT architecture.

Typical areas of application for PaaS and IoT:

• Connected machines (smart manufacturing): Sensors provide real-time data on temperature, utilisation or wear, which is analysed via the PaaS platform.
• Smart cities: Traffic flows, energy consumption or waste disposal are centrally managed via IoT applications.
• Connected cars: Vehicles send diagnostic data to the cloud, receive updates or support automated driving – managed via scalable PaaS infrastructures.
• Logistics solutions: Location data, inventory and supply chains can be tracked and adjusted in real time.

Choosing the right PaaS platform is a crucial step for companies developing complex software applications or wanting to future-proof their IoT infrastructure. It’s not just technical functions that matter, but also security, flexibility and integration capabilities.

• IBM Cloud: Strong focus on open source and high security standards. Well suited for industrial and enterprise applications.
• AWS (Amazon Web Services): IaaS platform with additional PaaS services such as Elastic Beanstalk.
• Microsoft Azure: Close integration with existing Microsoft products. Particularly attractive for companies with Windows infrastructure.

The Open Telekom Cloud (OTC) is primarily an IaaS solution. However, it provides companies with the foundation to build their own PaaS architectures – for example through managed Kubernetes, database services or container services. Combined with Telekom partnerships, e.g. with Microsoft Azure, it enables the creation of powerful PaaS environments with European infrastructure and high data protection standards.

With PaaS, your company can efficiently develop, operate and scale digital applications – without having to build its own infrastructure. Especially in combination with connected devices, data platforms and automated processes, PaaS forms a future-proof foundation for innovation across almost all industries.

The rule of thumb: Those who value European standards, data protection compliance and close integration with existing IT systems should choose a provider that focuses not only on technical functionality.
Telekom offers a powerful, GDPR-compliant infrastructure through its Open Telekom Cloud – operated in European data centres. In addition, with PaaS offerings based on OpenStack, German-language support and strong partners such as Microsoft Azure, it enables flexible and legally compliant cloud usage.

Whether for software development, IoT applications or hybrid platform strategies – Telekom provides a comprehensive portfolio of cloud services that allow companies to grow securely and scalably.
