What You Should Know About iPaaS

An Integration Platform as a Service, iPaaS for short, is a range of cloud services. They let an organization create, use and monitor data streams without needing to operate their own integration platform. It connects processes, services, applications and data within an organization’s own IT environment and beyond, including clouds. Using an iPaaS can help you meet your long-term cloud integration goals.

What exactly is an iPaaS and how does it work? What are the advantages and disadvantages of an iPaaS? What types of iPaaS providers are there? And most importantly, how do you find the right iPaaS solution for your business? Learn all about iPaaS here.

What Is iPaaS?

iPaaS stands for Integration Platform as a Service. Based in the cloud, it lets companies connect data, applications, processes and systems neatly, coherently and transparently. This allows companies to reap the benefits of modern and efficient cloud integration, namely seamlessly networked, reliable business and IT processes.

You often hear that using an iPaaS simplifies cloud integration work and makes it more accessible. Employees who need to perform integration tasks require little or no programming knowledge. This is embodied by the new role of the citizen integrator.

iPaaS is a coordinated collection of cloud services that ensures that data, applications, services and processes work together in a largely automated manner, both within a company and between organizations.

How Does iPaaS Work?

iPaaS means that a provider offers integration services on a public or private cloud. The integration platform has a full IT infrastructure, including solutions and tools for integration work, available online. The provider is also responsible for maintenance, updates, upgrades, security, and the scalability and reliability of the platform.

Companies using an iPaaS are only responsible for developing business processes, mapping and configuration work. The platform operator takes care of the rest. This lets companies concentrate on their core business. An iPaaS also lets you connect almost any third-party applications, services, and databases to an ERP or CRM system. This is useful when integrating clouds, SaaS or following a multi-cloud strategy.

Alternatively, the ERP or CRM system itself can be included in an overarching network such as a Hybrid Integration Platform (HIP) in a multinational company with subsidiaries, affiliates, and an ecosystem of customers, suppliers, and other stakeholders.

What Types of iPaas Providers Are There?

The iPaaS market contains providers of different sizes, offering services of varying depth.

Some iPaaS providers attempt to appeal to the broadest possible customer base with their services. Their clients will include small companies and start-ups as well as large international companies. These iPaaS providers tend to be large, well-known IT service providers.

Others are service providers that specialize in niche needs – also known as domain-specific iPaaS. An example would be reporting internationally traded goods, to national customs authorities (e.g. the EDI Service for SAP GTS) to ensure they comply with national regulations.

These niche providers tend to be smaller companies or start-ups. In practice, however, the boundaries are often blurred and many iPaaS service providers attempt to cover more than one sector.

Another category of iPaaS vendors is larger midsize companies that have a background in iPaaS-related services. This may be on-premises system integration or B2B integration. Over time, some of these companies have added both enterprise and domain-specific iPaaS solutions to their service portfolios. They regularly expand the breadth and depth of their offerings.

The number of active iPaaS providers worldwide is currently in the low hundreds, and is growing.

iPaaS Market: Yesterday, Today and Tomorrow

iPaaS in its current form is already over a decade old. The origin and growth of this integration method is closely linked to the growth of cloud computing and SaaS.

The first iPaaS providers

When the first SaaS providers entered the market, their customers needed help integrating cloud-based software solutions with each other and with their existing IT landscapes. The first iPaaS providers saw an opportunity there. They approached SaaS providers and offered them partnerships.

As a result, iPaaS providers benefited by not having to acquire customers. The SaaS providers benefitted as they could reduce – or even fully delegate – their integration work. This win-win situation fuelled the growth of both parties.

iPaaS is thriving: large software vendors are at the helm

As the IT world has become more complex, iPaaS approaches have evolved. New areas have emerged, including cloud-to-cloud, IIoT-to-on-premises and iPaaS-supported EDI. As a result, major software vendors such as SAP, Microsoft or Oracle started expanding their SaaS portfolio.

After working with iPaaS vendors for a while, they bought them out or developed their own iPaaS solutions. They wanted to make cloud and SaaS integration easier for their customers by closely integrate their own cloud solutions with their on-premises solutions.

Large providers have another advantage: they can scale via their partners or their own huge customer base. However, integrating third-party systems remains problematic with these approaches. This is why numerous other iPaaS providers have emerged in recent years with a focus on niche requirements. The domain-specific iPaaS providers mentioned above fall into this category. This all equates to a highly competitive market.

iPaaS: Choosing the right supplier in a dynamic market

If a market has growth potential, large providers often try to secure the lion's share while smaller providers occupy the niches. The smaller iPaaS providers therefore tend to have very specific knowledge in cloud or SaaS integration. This is often limited to one domain or even a sub-domain. Other providers position themselves somewhere in between.

Due to the continuing growth of SaaS and other cloud services, the integration services market remains attractive, drawing further providers to this market to get a piece of the pie. This could eventually lead to oversupply, after which the trend should reverse until it balances out.

It is therefore likely that many iPaaS vendors – particularly the smaller ones - will be bought out, will change their focus, or go out of business. It is critical to be aware of this when choosing an integration partner as it increases the risk and the potential of further costs. You also need to consider that it is difficult to transfer one provider’s mappings, workflows, and configurations to another.

Companies should therefore fully consider these issues before choosing an iPaaS partner. Chapter "Choosing the Right iPaas Solution for Your Organisation" on selecting the right iPaaS solution takes a closer look at this topic.

iPaaS & Integration Scenarios

Integration Domains

An iPaaS’s main strength lies in its ability to connect almost any combination of various data, applications and processes, and to integrate these across different IT environments. The most important environments or integration domains are:


Cloud-to-Cloud Integration

Their cost savings, high flexibility, and easy implementation and handling have made SaaS solutions very popular. Furthermore, because the barriers to entry are low, this SaaS market segment continues to grow faster than others. This is particularly true for SaaS integration. Indeed, this is also likely to account for the largest share in the future. It’s therefore worth taking a closer look at a multi-cloud strategy.

On-Premises-to-Cloud Integration

The term “on-premises-to-cloud” might trigger images of ‘dusty’ old legacy systems which need connecting to newer cloud solutions. However, the sale of on-premises software still accounts for a significant share of the software market.

While it is true that SaaS is growing strongly, new on-premises software will continue to play an important role in the coming years. The reasons for this include the fact that on-premises operation still seems attractive for highly individualized applications and software systems. There is a significant advantage to iPaaS-supported on-premises-to-cloud integration. An iPaaS expands the lifespan of existing and on-premises systems by seamlessly integrating them into a company’s cloud strategy.


Integration On-Premises-to-On-Premises

In an on-premises-to-on-premises integration approach, a company's data and applications either remain behind a firewall on premises or are hosted on a dedicated third-party server. It is crucial to be able to integrate on-premises software. It still plays a significant role in corporate IT environments, and is often intended to run for many years to come.

An example of the above would be synchronizing order data between a company’s sales, accounting and warehouse/shipping departments. Some iPaaS providers also provide on-premises solutions for this.

Integration Patterns

iPaaS vs. Other Integration Approaches

iPaaS is a newer way of integrating applications and processes, whether these are on premises or in the cloud. There are also older methods that are still used to a certain extent.

The Disadvantages of iPaaS

iPaaS is naturally not without its disadvantages. Although these are not limited to iPaaS, you need to be aware of their implications when choosing a sustainable integration method.

  • Not suited to niche or very specific needs

    Decent iPaaS solutions already cover a range of integration scenarios, and this is constantly increasing. In practice, however, there will always be scenarios for which the iPaaS market does not offer an answer. This may be because the solution required would need too high a level of technical customisation, or is generally not (yet) economical from the perspective of an iPaaS provider.

    You may find that if you have very specific integration needs, you’d be better served by a more traditional method such as ETL / hub-spoke / ESB or even point-to-point connections. Nevertheless, it is worth looking at how iPaaS can help you with your cloud integration needs. You may also want to combine an iPaaS with existing on-premises resources.

  • You need highly skilled personnel

    Citizen integrators are mentioned a lot in iPaaS discussions. While they certainly have a place, they can really only scratch the surface. Long term, you will need much more than integration tasks that are simple enough for drag & drop or point & click.

    Many integration tasks require advanced software or IT knowledge. As market and legislative forces are only making business processes more complex, this will not change in the foreseeable future.

    Furthermore, the majority of citizen integrators tend to be firefighting - solving their department’s most immediate issue. As a result, they can lose sight of the overall strategy. This can lead to data islands within the company. These are isolated, cobbled-together solutions, which are soon abandoned. Then, you will need IT professionals to tidy it all up.

    One way to prevent this development is to give citizen integrators professional support right from the start. This could come from in-house IT professionals, or from an iPaaS provider who finds skilled professionals to train the citizen integrators. In fact, many companies are completely rethinking the citizen integrator concept, and ploughing more money back into the IT budget.

  • It’s difficult to know who to choose

    Another disadvantage is that there is now a bewilderingly large number of iPaaS providers. These often focus on different areas and differ in the range of services they offer. Some try to cover as many scenarios as possible while others pursue a domain-specific strategy.

    Moreover, on comparison portals and in the trade press, more traditional integration providers who have since added iPaaS to their portfolio are sometimes lumped together with specialist iPaaS providers. For newcomers to the area, this makes it trickier to choose the right iPaaS provider.

The general shortcomings of iPaaS are not just the difficulty in finding a good provider, but that the technology doesn't offer much support for very specific functional needs.

The Advantages of iPaaS

The main benefits of iPaaS are as follows:

Lower costs

As SaaS applications become more prevalent, traditional integration methods quickly reach their limits, leading to expensive, unwieldly workarounds. iPaaS offers a more cost-effective alternative.


Scalability is one of iPaaS’s biggest strengths. If a company has grown through e.g. mergers and acquisitions, an iPaaS effortlessly connects the IT systems in the respective companies, both with each other and to the parent company.

Manage integration from one place

Another advantage is that you can manage an iPaaS's tools and services from one user interface, a little like a mixing desk.

Better availability and usability

SLAs tend to guarantee iPaaS availability to 99.99% or higher. Modern iPaaS solutions are more user-friendly than traditional ETL / hub-spoke / ESB approaches.

Multiple-tenant capability

Multi-tenancy means that processes have their own dedicated areas, even though they are actually sharing an environment. This means the customer can separate business areas and their respective integration needs, or even just have separate development, test and production environments.

Using an iPaaS as Part of a Long-Term Integration Strategy

A good iPaaS solution already covers a great many use cases in today's business world. It is often at the core of a modern integration strategy and may even fulfil the greater majority of a company's integration needs...

Nevertheless, many companies will not be able to make an iPaaS the centre of their integration strategy overnight. They will still have the obstacles of an existing integration jungle and an industry-specific or company-specific system or two to integrate. There are many reasons why the corporate world still relies on conventional integration technologies. Abandoning them prematurely would not make economic sense.

Many larger organizations, for example, already have in-house ETL/hub and spoke/ESP platforms, alongside specially trained personnel for these. In other companies, the point-to-point integrations are still doing their job well enough.

Even iPaaS solutions sometimes need supplementing, for example with a stand-alone  API management platform. You may also find that the connectors you need for new or niche SaaS applications are have not (yet) been developed. Essentially, you need to look at your IT ecosystem as a cohesive whole.

An iPaaS is a building block, albeit an important one, which must fit into the big technical and strategic picture long term. The result is often termed hybrid integration platform (HIP). As digital transformation continues to take root, iPaaS will most probably play an ever more significant role for many companies.
