Types of iPaaS Integration

1. Data Integration

The data integration process is based on collecting data from various source systems and organizing it centrally. This type of integration works in the context of BI (business intelligence) and big data – where immense amounts of data can be managed and analyzed quickly.

2. Application Integration

Application integration enables communication between cloud applications, on-premise systems, and apps in hybrid environments, often through APIs, allowing for easy synchronization of data across different apps. This is a great marketing automation tool for salespeople and marketers.

3. Cloud Integration

Cloud or cloud-based integration utilizes third-party tools or in-house resources to integrate your company's SaaS applications and legacy systems, keeping data in sync across these apps and systems.

How iPaaS Differs from Other Cloud Services

iPaaS vs. PaaS vs. SaaS

• Platform as a Service (PaaS) is a type of cloud toolbox that allows developers to create, run, and manage applications without the need to build and maintain the underlying infrastructure (servers, storage, etc.). IPaaS combines multiple platforms to prioritize application and data integration, leveraging the same advantages as PaaS but on a broader scope.
• IPaaS solutions enable hybrid integration of variety of applications, both cloud and on-premise. IPaaS offers the smooth exchange and integration of data from the connected applications and systems.
• Software as a Service (SaaS) delivers software applications over the internet on a subscription basis, allowing users to access and use the software via a web browser without needing to install or maintain it locally. SaaS applications are fully hosted and managed by the service provider, who handles maintenance, updates, security, and scalability. IPaaS tools can streamline the integration of SaaS and on-premise deployments. Those tools are the most effective when interfacing with pre-existing legacy systems and extend the digital environment of the company by adding new systems on the integration platform. 

iPaaS vs. ESB vs. API

• Enterprise Service Bus (ESB) is usually run on-premises to integrate local or legacy systems. Conversely, iPaaS is typically cloud-based and can seamlessly integrate applications from both cloud-based and on-premise environments, including those from third-party sources. An ESB may provide a more straightforward and controllable integration method suitable for traditional organizations with minimal external workloads or smaller data volumes.
• Application Programming Interface (API) management comprises a series of procedures and technology enabling organizations to construct, operate, and assess APIs within cloud environments. Compared to iPaaS, API  is a broader concept that defines the rules and protocols for communication between software applications, enabling integration as well as other functionalities such as extension and customization.
