An orchestration layer is a software component that manages how different systems coordinate with one another. It can automate workflows by triggering tasks across connected tools or transform data as it moves between services, making it particularly valuable when working with large language models (LLMs).

The orchestration layer often operates within a broader integration setup, which connects separate systems so that information can move between them. While integration enables the connection, orchestration enhances it by shaping how processes unfold and the ways each system responds.

To build an orchestration layer, developers define rules that determine when tasks begin and how different components interact. The result is a system where operations run in a controlled sequence, allowing tools to work together without manual coordination.

Core functions of an orchestration layer 

An orchestration layer plays a key role in how modern systems operate behind the scenes. It acts as the control center for managing automated processes and ensures that actions take place in the correct way.

The following functions highlight how orchestration layers maintain order across increasingly complex environments.

Defining workflows and dependencies

At the heart of orchestration is the ability to define how tasks relate to one another. Some tasks can run at the same time, while others must wait for earlier steps to complete. Developers can express task relationships clearly with an orchestration layer, which helps to keep workflows predictable and reliable.

Scheduling and triggering tasks

When a workflow has been defined, the orchestration layer will take responsibility for when it begins. It may start at a fixed time or in response to a specific event. Whether the trigger is a new file being uploaded or a process finishing in another system, the orchestration layer will react and trigger the next task accordingly. 

Coordinating system resources

Different tasks often rely on shared computing resources. The orchestration layer helps to manage how those resources are allocated and makes sure that no single process will overload the system. It prevents conflicts and ensures tasks receive the capacity they need to run without issues.

Managing execution and resilience

Sometimes tasks will fail or stall due to disruptions such as missing data or network problems. The orchestration layer monitors each step and can reroute workflows or automatically retry failed tasks when necessary. Fallback mechanisms like these help to maintain the stability of the system.

Monitoring performance and logs

Visibility is a vital element of component systems. An orchestration layer will provide logs and status updates for each task. People can then track performance and identify any delays or troubleshoot errors with ease to improve operations.

Orchestration layer use cases

Orchestration layers have many use cases. For example, in retail AI transformations, enterprise layers coordinate functional and foundational systems to manage multi-step operations across departments.

In banking, McKinsey describes the decision-making layer as the “brain” of the AI-first enterprise. When AI agents are coordinated by an orchestration layer, they unlock productivity and form the basis of more engaging experiences.

Tools like Maestro from AI21 apply orchestration to deliver structured results across a range of sector use cases. Below are three examples:

Enterprise deep research

Research across large document sets often involves complex, multi-part questions. Maestro handles these by orchestrating tasks into discrete steps, retrieving relevant information using Retrieval-Augmented Generation (RAG), and validating outputs against defined requirements to ensure accuracy and relevance.

Complex document analysis

Legal and financial sectors often work with long, complex documents where critical details must not be missed. Maestro orchestrates how these documents are processed by guiding tasks such as summarizing earnings calls or comparing versions of contracts. It plans which parts of the document to prioritize and how to sequence analysis steps, using dynamic evaluation to generate results that meet task-specific requirements.

Data extraction

Many businesses need to extract structured insights from complex or inconsistent documents. Maestro orchestrates each stage of this process by breaking down tasks and retrieving relevant content before validating results. It supports use cases such as analyzing regulatory documents or migrating unstructured data from legacy systems into structured, modern platforms.
