What is middleware?

what is middleware


Middleware is a software that allows one or more types of communication between multiple applications or app components in a distributed network. Middleware helps to streamline the app development process by connecting app components easily and by offering functionality to connect them in an improved way.

There are different types of middleware for different applications. For instance, message brokers or transaction processing middleware for communication purposes. Web app servers or mobile device middleware for a wide range of communication and connectivity features required to develop a specific type of application. Others like a cloud-based integration platform as a service (iPaaS) providing an enterprise service bus and works like a dedicated integration hub to connect multiple components in an enterprise. There is a type of middleware to build your own custom middleware.

The very first middleware acted like a mediator between an application front-end, or client and a back-end resource. For instance, a database app or special hardware device from which the client might request data. This is the reason it was named Middleware. Having said that, today’s middleware offers a lot more options. 

How middleware works?

how middleware works


At a simpler level, middleware allows developers to develop applications without building a custom integration every time they need to connect to app components, data sources or computing devices. This is done by offering solutions that allow various apps and services to communicate with each other using frameworks like JSON (JavaScript object notation), REST (representational state transfer), XML (extensible markup language), SOAP (simple object access protocol), or web services. Basically, middleware also offers solutions that allow components written in Java, C++, PHP, and Python to communicate with each other effectively.

Along with that, middleware also comprises of services that assist developers in a number of ways including:

  • Configure and control integrations and connections. Depending on the information offered by a client or front-end app request, middleware can tailor the response from the back-end app or service. In a retailer’s ecommerce app, middleware app logic can sort product search results from the inventory database by the closest store location depending on the IP address or location information in the HTTP request header.
  • Protect connections and data transfer. Middleware generally builds a secure connection from the front-end app to back-end data sources using Transport Layer Security (TSL) or another network security protocol. 
  • Handle traffic dynamically across distributed systems. When app traffic increases, enterprise middleware can escalate to deliver client requests across different servers, on premises or in the cloud. Moreover, processing abilities can forbid issues when various clients try to access the same back-end data source at the same time.

What are the different types of middleware?

There are various types of middleware. Some focus on the connectivity, while others focus on particular apps, application components and devices whereas some mix the middleware abilities for a particular development task.

Some of the widely used middleware software are:

  • Message oriented middleware (MOM) allows application components using various messaging protocols to engage. Along with translating or transforming messages between apps, MOM handles message routing of messages. Hence, they always get to the appropriate components in a convenient order. For instance, message queues and message brokers are a type of MOM.
  • Remote Procedure Call (RPC) middleware allows one app to initiate a procedure in another app on the same device or on an alternate device or network. This works as though both are part of the same app or same device.
  • Data or database middleware streamlines access to, and interaction with, back-end databases. A database middleware is very similar to a SQL database server.
  • API (Application Programming Interface) middleware offers tools that the developers can leverage to build, expose and manage APIs for their applications. This is done so that other developers can connect together. Certain API middleware comes with tools to monetize APIs – which allows other enterprises to use them by paying a premium cost. For instance, API middleware consists of API management platforms, API gateways and API developer platforms.
  • Object Request Broker (ORB) middleware functions like a broker between a request from one app object or component, and the execution of that request by another object or component on the shared network. ORBs work with the Common Object Request Broker Architecture (CORBA), which allows one software component to make a request of another object without knowing where the other is hosted.
  • Transactional middleware offers solutions to sustain the execution of data transactions across a shared network. Some of the best transactional middleware are transaction processing monitors (TPMs), which makes sure that transactions begin from one step to the next till the completion. These include data exchange, adding/changing/deleting data where necessary and more.
  • Asynchronous data streaming middleware duplicates a data stream in an intermediate store, allowing data sharing between different apps. Apache Kafka is an ideal example of middleware for real-time data streaming.
  • Device middleware offers a dedicated set of integration and connectivity features to build applications for a particular mobile OS.
  • Portal middleware offers tools and resources for integrating content and abilities from different applications to build a single, uniform application.
  • Robotics middleware streamlines the robotic hardware integration, firmware and software from various locations and manufacturers.

Enterprise Application Integration Middleware

Enterprise app integration middleware allows an enterprise to establish an enterprise integration hub. It is a simple way to link all apps, app components, business processes and back-end data sources in the extended enterprise.

Till a decade ago, the most predominant enterprise app integration middleware was the enterprise service bus (ESB). It acted as the integration hub in a service oriented architecture (SOA). Currently, a cloud hosted model known as integration platform-as-a-service or iPaaS allows an enterprise to connect apps, data, processes and services across multiple on-premises, private cloud, and public cloud environments. This can be done without the additional work and cost of investing, installing, handling, and maintaining the integration middleware in its own data center.

Platform Middleware

Platform middleware or application platform middleware can bolster app development and expedite application delivery by offering a runtime hosting environment like a Java runtime environment (Java RE), or containers, or both for app or business logic. Platform middleware can entail or merge enterprise application servers, web servers, and content management systems along with different middleware types listed in this section.

Middleware and cloud-native applications

Cloud-native is an app development process that uses profound cloud computing technologies, with the primary objective of offering seamless development, deployment and management throughout on-premises, private cloud or public cloud environments.

Currently, cloud native apps are apps developed from microservices, and deployed in containers coordinated via Kubernetes. Microservices are app components that include their own stack, and can be deployed and managed independently, and engage with one another with the help of REST APIs, message brokers and event streams. Containers are lightweight executables that package app code like microservices with the OS libraries and dependencies required to run the code on any cloud infrastructure.

Together, the related technologies build a significant, build-once-deploy-anywhere platform to deliver net-new hybrid cloud apps. This is done to improve the conventional legacy systems to be used in the cloud. However, they also lead to an intricate development environment that incorporates more software apps, data sources, programming languages, tools and distributed systems.

Middleware can eradicate this complexity, though running containerized apps with conventional middleware can include complexities of its own along with infrastructure overhead that containers were designed to remove. Due to this reason, prominent cloud app development platforms like Cloud Foundry and Red Hat OpenShift improved to add containerized middleware.

Why is there a growing demand for the Infrastructure Middleware Market?

Mobility for users along with businesses is a current trend towards improving employee-consumer interaction and increased operational efficiency using various devices. Around 70% of the workforce is predicted to adopt its own devices for work which will increase the requirement for mobile middleware for data security and remote data access management.

The rising acceptance of IoT in the user and business landscape along with adoption of the 5G network in 2021, the number of IoT devices is expected to increase rapidly. As per Ericsson, the global smartphone subscription was USD 5.6 billion in 2019 and is expected to reach USD 7.4 billion by 2025.

As public cloud becomes a normal deployment solution, more businesses are likely to adopt the public cloud to migrate, build or rebuild their crucial customer-focussed apps and assets which will increase the need for middleware solutions.

Though, a significant challenge to the middleware infrastructure market growth is the presence of open-source software along with the failure of important vendors to offer PaaS offerings to enterprises.

The current COVID-19 induced pandemic is slated to induce a short-term rise in demand with the rising use of API and other services from collective infrastructure. However, in the next few years, with the rise in demand, the number of businesses shifting to digital infrastructure is going to rise significantly.
