Integrations

Change one system without rewriting the rest

The integration layer cures four ailments of rigid data exchange: data loss, cascading rework, source overload and inconsistency. ESB, Kafka and n8n solve different problems.

50flows in 6 months — a speed benchmark for an ESB project

48flows in production with a target loosely coupled architecture

16xfaster launch of standard integrations compared to code

ESB

Routing, transformation, guaranteed delivery and low-code support of legacy exchanges.

Kafka

Durable log: an event is stored, re-read, multiple consumers read at their own pace.

n8n

Fast orchestration of a process and AI steps where heavy event streaming isn't needed.

up to 16xfaster to build integration through a bus than point-to-point in code

13 yearswe build integrations for mid-sized and large businesses

The bus keeps systems from needing to know about each other

Every direct integration ties together the release cycles of two systems: update one, and you have to revise the other.
With ten systems, that is up to 45 pairwise links, and any one of them can break with the next release.
The integration bus takes over the data exchange.
The source sends data once in its preferred format; the bus stores messages, transforms them, and delivers them to recipients.
Replacing or upgrading a system changes one adapter on the bus, not a cascade of pairwise integrations.
This is loose coupling, which DORA links to delivery speed and stability.

What changes after bus implementation

Point to point

Every new system becomes a separate integration project with each neighbor
A developer tracks the error through logs from two systems
If one system fails, neighboring systems can fail in a cascade
Data in the systems contradicts itself

Through the bus

A new system connects to existing flows in a few days
A support operator isolates the error using bus monitoring
Systems are isolated: messages wait in a queue and are delivered after recovery
The bus keeps message history; lost messages can be restored without custom fixes

The source sends data once. The bus stores, transforms, and delivers it, and recipients do not know about each other.

We choose the tool for the task, not for the trend

We start by assessing the system landscape, workload, licensing requirements, and team expertise. Where KT.Team has a public case, we link to it; for n8n, to our analysis of use cases and limitations.

Tool	When we choose it	Constraint	KT.Team experience
n8n	Lightweight processes and automation when launch in days matters	Complex logic requires JavaScript and engineering oversight	n8n use cases and limitations
Datareon	Enterprise environment with 1C, MDM, and master data	Proprietary delivery: we include licenses and support in TCO	Developer case: Datareon integrations
Apache Kafka	High-load event streams and asynchronous exchange	Kafka is a broker, not a ready-made bus: routing, transformation, and monitoring must be built around it	Furniture holding case study
MuleSoft	API-led architecture and reusable APIs across a large system landscape	Commercial platform: we include Anypoint licenses and expertise in TCO	Fix Price: supplier portal
Talend ESB	Jobs and data transformations when integration logic is easier to assemble than build from scratch	Before scaling, we define the version, support model, and job owners	Logistics: integrations 4x faster
WSO2	Open-source enterprise integration when you need API management alongside the bus	Open source without vendor lock-in; higher entry barrier for the team	Marketplaces via WSO2

A detailed breakdown of licensing, community, and fault tolerance is in the article comparison of ESB solutions in the CIS market.

How we implement

01
Pre-project assessment
Map of systems and data flows (SOA diagram): what moves, from where to where, and where the business loses speed.
02
Pilot flow
The first flow on the chosen tool across three environments: test, preprod, production.
03
Scaling
Flows are copied and adapted for new systems; each connector gets up to three monitoring dashboards.
04
Support handoff
Documentation for copying and maintaining integrations; errors are handled by the operator, not the developer.

We build integrations that

No data loss

The bus stores message history. Even if the target system did not accept a thousand messages, they can be restored without involving developers.

Maintained by an operator

A self-documenting low-code layer with built-in monitoring: the support operator isolates the issue by following the instructions.

Not tied to a vendor

The integration code is packaged as a standalone service (JAR or Docker image); the tool can be replaced without rewriting the setup.

All reviews

The KT.Team team is a mature development partner. The delivery process is very clearly organized, and the smooth collaboration within the engineering team deserves special mention. When the team sees that the development process needs fine-tuning, it does it. During discussions, the team digs into the essence of the tasks and seeks to understand the business context. The work is aimed not at formally fulfilling the specification but at solving the real problem. Thanks to strong engineering expertise and product thinking, the team can be trusted not only with implementation but also with the architecture of the entire system.

Vadim MizhenskyHead of Digital Product Development, FSK Group

The Muztorg group of companies has been working successfully with the KT.Team team for more than two years. The high professionalism of our partners helps us a great deal, as does their ability to combine well-structured project management with minimal formal constraints. I would especially like to note the friendliness and openness of the KT.Team staff.

Dmitry SavelievBoard Advisor on Digital Development, Muztorg

You set a high standard for working with contractors. After you, dealing with others leaves a feeling of falling short of expectations.

Project estimation

We will calculate the timeline and cost of bus implementation

We start with a pre-project assessment: a map of systems and flows, the right tool for the task, and a pilot flow plan.
