Cloud Middleware

Cloud Middleware

"Something goes in somewhere and something comes out somewhere" - this could be a very simplified definition of middleware. But unfortunately it is not quite that easy. We clarify what middleware is, what it is good for, the significance of cloud middleware, what the advantages are and how it is used.  

So, let's jump right in.

What Is Middleware?

The name says it all: a middleware issoftware that works between two other applications. These two applications are an operating system or an application on one side and other running apps on the other. The middleware is therefore a middleman that provides services and functions for these apps. However, users usually do not notice this, as middleware acts invisibly in the background and is to be understood as a glue.  

Why All This? Why Not Simply Connect The Operating System and Apps or Apps and Apps Directly with Each Other?

Because unfortunately that is not always possible. Like interpreters for people, middleware is sometimes needed as a translation tool to mediate between two languages or applications. In this way, applications become compatible that were not before. Middleware can handle data management, data transfer, application services, messaging, authentication or API management. In short, data or entire databases can be shared by both applications, and the middleware translates them into the respective language of the application.  

But Why The Effort? Aka. What Is Middleware Good for?

Middleware builds bridges between other applications, databases or tools to provide users with a seamless application experience.  

As a service provider for cloud automation, we deal with these seamless customer and employee journeys on a daily basis. Middleware is therefore essential, especially for the world in the cloud. By connecting applications, whether through middleware or other technologies, we save time, create simpler, more efficient workflows and increase productivity. All by letting applications communicate directly with each other, rather than having people in between.  

Cloud middleware is a particularly efficient and cost-effective way to connect the execution of applications and makes them enormously scalable. This means that even as your company grows, the middleware grows with it.

Example Middleware

To illustrate what I have just described, here is an example from our work as a cloud middleware service provider. Here we worked with Make.

Example from a project

In the first place, there is an interface from which the relevant data for this process are drawn. This data is then evaluated (according to certain criteria) and modified if necessary. If certain defined conditions are met, the data is enriched by further interfaces, which is structured in detail like this:  

Data runs into the process and is checked for a value, for example, whether a customer number is present in the data supplied.  

If there is no customer number, then this is added through another interface.  

The next step is to check whether the customer number already exists. If not, a new customer is created (this can be seen in the upper part of the first branch).  

If the customer number already exists, further data is fetched and added via a third software (the lower part of the first branch).  

The next check refers to the number of products.  

If only one product was ordered (lower part of the second branch, highlighted in purple), a certain variable is set that indicates that the customer can cancel the product at time X or that the product will expire at this time. This information is then sent to another app.

If several products have been ordered, information about the different cancellation dates, billing periods and variants is provided. These are obtained via another interface. Finally, the data is transferred back to the original tool.  

If necessary, all data obtained and processed are stored in another database.  

Other examples of middleware applications include:

Many websites have ready-made contact forms. When these are filled out, the data is "translated" by middleware and then stored in a database. This means that the data is immediately visible to the company and can be used in the right place.  

Cookies are used to create individual user experiences. YouTube, for example, uses middleware to present an individualised homepage to all users, depending on their preferences and history.  


One form of middleware that accompanies us every day is a programming interface or Application Programming Interfaces (API). This interface is usually provided by applications and thus enables the integration of a wide variety of applications on a specific operating system. In this way, apps communicate with each other and a wide variety of services and products are linked together.

APIs are indispensable in the digital world. They enable us to use external offers, i.e. services, applications or devices, in the company and, conversely, to link the offers and services of companies with external platforms such as Google and thus reach a broader target group.

Cloud Middleware and Its Advantages

To our delight, the integration of a wide variety of applications by means of middleware is increasingly taking place in the cloud. Cloud middleware adapts flexibly to the requirements of the company and is thus enormously flexible and versatile.  

The term Middleware as a Service (MWaaS) is thus becoming increasingly important in this context.


Middleware as a Service

Integration platform as a Service (iPaaS) is certainly no longer a niche trend and, following it, Middleware as a Service is also becoming an increasingly used term. What is meant by this?

The provision of middleware as a service means a prefabricated package of cloud-based automation services to be used for complex, compound automations. This results in a MWaaS suite.

This includes various cloud services, API integrations, API management, B2B integration and the integration of data sources. Thus, iPaaS, apiPaaS, mobile backend as a service (MBaaS) and other cloud-based integration services are combined in a MWaaS suite. The goal is to automate and support digital business processes, customer journeys and employee journeys in the best possible way.  

So: Middleware as a Service is a mixture and a package of various cloud automation services and services that are quickly and flexibly ready for use for a wide range of scenarios, companies and processes.  

Advantages of Cloud Middleware

As already mentioned, middleware takes on a variety of tasks that are fundamentally based on making data and databases available to countless applications and translating them if necessary.  

In this way, middleware acts as a link between applications, data and users without being visible.  

Creating a high-performance and scalable software architecture in a company can become increasingly difficult due to countless developments. More and more different tools, languages or frameworks are being used and make ever new demands. Nevertheless, the software architecture is expected to perform efficiently, guarantee low costs and make the entire company more productive.  

To meet all these requirements and the increasing complexity of such environments, middleware can provide a fast and cost-effective solution for integrating all applications, services and systems. Middleware supports smooth, reliable operation of all relevant applications, regardless of their environment.  

But Why Cloud Middleware?

The advantages of cloud middleware are the same advantages that cloud applications generally bring with them:

Cloud computing is a growing market. More and more cloud services and suites are being developed and offered, so the choice for businesses is immense

Cloud solutions are mostly cheaper, easy to implement and agile to use

Thus, cloud middleware creates a fast and flexible integration of applications

Cloud solutions are more scalable and less sensitive to change, innovation or restructuring

Cloud middleware is future-oriented:

IPaaS and MWaaS are fast growing markets and cloud middleware is increasingly the first choice for middleware as opposed to in-house middleware. Investments for iPaaS are steadily increasing and especially in the international market there is no way around middleware

Conclusion: Cloud Middleware for The Enterprise

Middleware is essential for high-performance integration and automation. It is the glue and intermediary between the most diverse applications and thus opens up countless possibilities to let applications talk to each other.

The demand for cloud middleware, its possibilities and its market potential are constantly growing, which is why we use cloud middleware directly or indirectly in almost every customer project.

Cloud middleware and MWaaS also offer the greatest agility and flexibility in everyday business and even if the terminology is not yet 100 per cent understood and there is still a lot happening in the market, these technologies are fundamental for cloud automation, business process automation and all things digital.

Last but not least, MWaaS, as a further development of iPaaS, offers a short time-to-integration, low operating costs and an increase in productivity throughout the entire organization.
