Enterprise integration uses technologies and methodologies to integrate business applications, data, processes, and devices across the entire IT landscape. Enterprise integration is important because it connects functionality and communication across systems, allowing organizations to react quickly to the needs of the business and become a more responsive, agile enterprise.

A holistic approach to integration helps to resolve the complexity of most enterprise environments where an ever-growing sprawl of applications and data has made it difficult to manage the business. Enterprise integration takes a holistic approach to solving integration challenges by bringing together the separate data and application integration disciplines into one combined effort with one governance model.

With enterprise integration, organizations can connect customers, employees, and partners to all applications, processes, systems, and other technologies that drive the business.

The evolution of enterprise integration

Interest in enterprise integration solutions started in the early days of application management. Integration was an aspirational goal and focused primarily on data integration, especially within the manufacturing sector where computer-integrated manufacturing (CIM) was taking off.

By the 1990s, enterprise integration became a focal point as businesses grappled with a multitude of applications, all working in isolation from each other. The value of integrating these disparate systems to create unity across the enterprise was clear. However, initial efforts to integrate systems involved point-to-point integrations from one business application to another, using data integration software. This linear approach did not address the objective of building and maintaining a consistent and secure integration framework for the entire enterprise.

Today, enterprise integration has become a strategic imperative, especially given the exponential growth of disparate applications and data as companies adopt more cloud solutions. Many CIOs view enterprise integration as the cornerstone to unlocking greater responsiveness and agility.

Enterprise integration is quickly gaining ground, with organizations around the world incorporating the strategy to optimize efficiencies and transform their businesses. For example, Zuellig Pharma Holdings Pte. Ltd., one of the largest healthcare services groups in Asia, uses cloud-based integration to make healthcare more accessible in 13 Asian markets.

Problems solved by enterprise integration

As illustrated above, enterprise integration can help to resolve long-standing inefficiencies across a business, including:

By implementing enterprise integration, organizations can support real-time, digital interactions. The result is greater business velocity and collaboration within a broader ecosystem of customers, co-creators, suppliers, and partners.

Types of integration

There are a number of types of enterprise integration that connect critical systems and applications across all lines of business within an organization and drive benefits.

  1. Application integration: With application integration, processes and data can be optimized, integrated, and shared between separate software applications in real-time to deliver improved insights, visibility, and productivity across the organization.
  2. Data integration: With data integration, information – or data – is discovered, retrieved, and compiled from disparate sources into a structured and unified view.
  3. Process integration: With process integration, workflows and processes that span multiple applications and systems can be optimized and orchestrated to transform operations and drive efficiency.
  4. Device integration: With device integration, different devices are connected so they can communicate, interact, and interoperate to support business needs and drive productivity.

In summary, by integrating applications, data, processes, and devices, business leaders can leverage real-time data and processes from across the organization to make informed decisions. With no need to aggregate and update systems manually, people will be more productive, using real-time data on demand to work more efficiently. Customer experiences are also enriched with faster, more satisfying interactions.

Best practices in enterprise integration

By disseminating knowledge and standardized processes across the enterprise, an ICoE can mitigate unnecessary duplication of projects, boosting speed, efficiency, and effectiveness. This allows companies to more easily integrate processes, data, and applications in a coherent, scalable, and cost-effective manner.

With an ICoE, organizations can expect:

  • Accelerated project delivery time
  • Operational and IT budget efficiencies by investing in technology solutions that serve multiple projects
  • Lower maintenance costs
  • Improved ROI through the creation and reuse of enterprise assets such as source definitions, application interfaces, and codified business rules

FAQs about enterprise integration

This strategy will be most helpful to businesses that are grappling with the exponential growth of disparate applications and data. Often, this is due to the adoption of different cloud and on-premise solutions over time. Enterprise integration consolidates these unconnected components, with all applications using a common data model to work together in real time. This model approaches integration holistically and can serve businesses of all sizes.

Enterprise integration supports a range of recipients within the business and beyond:

  • Leaders can leverage real-time data from across the organization to make informed business decisions.
  • Workers can be more productive using real-time data on demand, replacing manual, time-consuming processes.
  • Customer experiences are enriched with faster, more satisfying outcomes.
  • Partner and collaborator interactions with the business are seamless.

Integration platform-as-a-service (iPaaS) supports projects involving any number of cloud and on-premise endpoints, including APIs, mobile devices, and the Internet of Things (IoT). The model develops, deploys, executes, manages, and monitors integration processes and flows that connect multiple components so they can work together.

Although this model delivers integration within the enterprise, it does not support enterprise-class integration given its narrow scope and focus, which is typically applied to a single line of business.
