Do you know what a middleware is? You probably don't know that the vast majority of business processes have been digitized and, inadvertently, companies often use multiple hardware and software products that have not been developed with the same programming language.

Definition of middleware:

A middleware is software that sits between an operating system and the applications that run on it. It is, in essence, a kind of “translation layer” hidden that enables communication and data management in distributed applications.

In other words, it is like a network of pipes connecting two applications so that data and databases can be easily exchanged. Its use enables users to make requests, like submitting forms in a web browser or having a web server return dynamic web pages based on a user's profile.

Origin and history of middleware:

The term middleware first appeared in a report from the NATO conference of 1968, whose objective was to establish the field of software engineering and included the design, software production and distribution. The intention was that the new software could connect with other older systems.

Why is middleware essential for cloud computing?

Now that you know what middleware is, you should pay attention that, despite all the benefits of cloud-native development, it also implies additional complexity. Applications can be implemented in many infrastructures, from local systems to public clouds.

And it is that architectures can vary considerably, so developers must coordinate various tools, languages ​​and frameworks. There is also additional pressure to achieve more goals in less time and at lower cost.. Something logical on the other hand.

Companies are using middleware as a way to address this complexity and to get the most out of application development.. This should not surprise us, since the middleware supports application environments that run smoothly and uniformly on a highly distributed platform.

Types of middleware:

Middleware ranges from web servers to authentication systems and messaging tools. Therefore, some common use cases for middleware in modern development are as follows.

Smart business automation

Middleware is a boon for developers, architects and business and IT leaders who want to automate manual decisions to drive resource management and overall efficiency.

Application programming interfaces (API)

Many of the middleware services are accessed via APIs (tool sets, definitions and protocols that enable applications to communicate with each other), that allow totally different products and services to connect with a common layer.

Data transmission

To continue understanding what a middleware is, it is necessary to know that, although APIs are a way of sharing data, another way is asynchronous data transmission, that replicates a dataset to a staging store where the data can be shared. between various applications.

Full integration

Middleware integration tools connect essential internal and external systems. Integration functions, such as business messaging, the composition, transformation and connectivity, combined with SSO authentication, enable developers to easily extend capabilities to other applications.

Optimization of current applications

Middleware helps developers transform legacy monolithic applications into cloud-native applications, keeping important tools alive with improved performance and greater portability.

Development of new applications

Middleware enables modern and well-known runtimes for various use cases. Developers and architects can quickly work across platforms, referencing sets of basic programming languages, frames and execution times.

At the same time, middleware offers the most used functions, like in-memory caching, the courier, single sign-on (SSO) or web servers.

Middleware role in application development:

Modern business applications are designed to run at scale, on premises and in the cloud. What is a middleware without an application environment with unified basic functions? Middleware is the key to achieving this type of environment, so its functions can be thought of in terms of four layers:

Container layer

This middleware layer manages everything that has to do with the distribution of application life cycles in a uniform way.. Offers DevOps functionality along with seamless integration and delivery (THERE / CD), container management and utility network.

Runtime layer

This layer contains the runtimes for the custom code. Offers lightweight frameworks and runtimes for highly distributed cloud environments, as messaging services to speed up the transfer of such data, in-memory caching for fast access to data and microservices.

Integration layer

This layer provides services that are used to connect purchased and custom applications, as well as SaaS resources to form functional systems through messaging, integration and API. It also offers cache and in-memory database services, data or event transmission and API management.

Process automation and decision management layer

This layer incorporates fundamental decision management, optimization and automation, and intelligence.

Middleware, the “translator” multipurpose code

Understand the 100% what is middleware can be difficult, But it is clearly evolving rapidly to help transform companies and succeed in the digital economy..
