Orchestration vs Choreography - Which is better?

Due to some exceptional features, microservices are widely employed in the building of complicated apps. There are several ways you can employ this development practice. The most favored methods among these are orchestration and choreography. 

Each one offers unique features and has a certain combination of benefits and drawbacks. Before choosing a strategy, you must comprehend each of these factors.

Orchestration vs Choreography - Which is better?

What Are Microservices Orchestration and How Do They Work?

To put it simply, it is the logical service management entity that is used to combine several services and enable them to communicate data inside. 

Its foundation is the orchestra theory.

The process uses several microservices interacting together to form an application, just like a real-time orchestra band does to produce a masterpiece.

The microservices, in this scenario, are similar to how individual musicians collaborate together to ensure that good music is formed.

The conductor’s usage and role are also considered important here. In a musical orchestra, its counterpart’s job is to make sure that each player is competent to play their part and has access to notes of the song to be played. 

The conductor is here to make sure that every musician is playing the notes in the correct order.

In Microservices orchestration, the conductor acts as the parent service taking care of the requests. It ensures that all the linked services can view the request and fetch the crucial data accordingly.

Parent service gathers all responses given by the corresponding services and forwards them to the main service, the orchestrator. It hands the details over to the client application and is responsible for establishing continual communication with every service that is important for API request processing.


Advantages and Shortcomings of Orchestration


  • Centralized access and observability to all the key workflows and data

The orchestration framework works utilizing individual services. Instead of keeping the overall application on surveillance, it keeps an eye on every individual process that is related to creating the application. It regularly gathers data from specific processes and makes them available for examination. Because of this, developers will be able to understand the workflow in parts and, thus, more efficiently.

  • Processes are synchronous

With orchestration, improving workflow is easier, as mentioned above, and developers can synchronize all of them according to the development needs.

  • Easy scalability is possible

As orchestration helps you have an eye on all the processes from the foundational level, scalability is quick and easy to attain. 

You can coordinate with diverse transactions happening around a microservice and pair them smoothly with the overall application.

  • Quick error tracing

With orchestration, it’s easy to find out where the error that is existing within a workflow. Not only errors of bugs are spotted, but developers are also able to find out why the error occurred and how one can debug it.

While all these benefits are lucrative, we must not overlook their limitations, which are many. For instance, it’s too time-consuming. A single application development can involve thousands of services, and their synchronization will take too much time. 


Other than being time-consuming, Microservices orchestration is a dependent approach. Orchestrators have to be in touch with every microservice to make sure data access is possible. They will not be able to work if data is not there.

As orchestration keeps every microservice linked together, failure in one service will cause failure in the entire chain.


As you plan to use this approach, you need to learn about some of the best Microservices orchestration tools that will make this approach implementation easier than ever. Kubernetes is the best-known orchestration tool to use. It has a wider scope, offers multiple features, and works in almost all development scenarios. It’s used as an orchestrator in this approach.

If you’re looking for Kubernetes alternatives, then you can try Docker Swarm and Mesos. They all work in the same way and are very practical. 

Crossplane is another CNCF-managed orchestration platform that is still in the incubation phase. Five more orchestrators, Karmada, Fluid, Volcano, wasmCloud, and Open Cluster Management, will be soon ready to help you.


Microservices Choreography: What Is It And How Does It Work?

Choreography in Microservices is the exact opposite of Orchestration in this context. It’s a completely decentralized approach and involves the staging of services. The real-time analogy of this concept is choreographers in a dance troupe that doesn’t perform the dance itself but stages the performance for the dancers.

Just like dancers of a dancing group are responsible for playing their roles indecently, microservices in the choreography approach are accountable for their workflows. 

It also has the concept of an orchestrator, which is mostly a middleware like Kubernetes. Here, this element is redundant and remains at the center of this approach. All lightweight services are self-sustaining and are capable of working without any 3rd party intervention. 

Microservices are loosely coupled and make development highly flexible. Because of these loosely coupled services, this approach makes the application development a little less complex, as actions of one service will not influence other aspects. It doesn’t demand any controller for individual programming and management. 

There is also no single node in this approach. So, the legit question here is:

How does communication take place when the middleware is absent?

Well, the key component for this approach is the Event Broker that is also known as Message Broker. Microservices, bound with this approach, work based on the messages received from other associated services in the channel. Every microservice is aware of its responsibilities as they are event-driven automatically. 

Because of this process, communication keeps on happening asynchronously. Microservices listen to the Event Broker and act accordingly.

The approach also uses loose service coupling logic that permits involved Microservices in modifying as necessary. While it happens, the underlying logic remains unchanged or unaffected. 

Advantages and Shortcomings of Choreography


The use of Choreography pattern Microservices has substantial pros and cons, and an ideal user is one that knows both these aspects very well. 

Let’s start with the pros first. This approach is ideal for automating the entire message exchange process with the least possible effort. As a highly effective and distributed control logic is at work, message automation remains an easy task.

Unlike orchestration, it’s not very dependent. Every microservice has its stand and process. This is why there is no single point of failure. Errors and bugs remain contained within a given architecture. When it comes to scalability, choreography has an upper edge as compared to orchestration.

Scalability is also easy-to-achieve as you can make it happen without any performance loss. Lastly, we would like to add to the benefits list the fact that this approach would like to modify the processes without disturbing the key logic of the app. This makes Choreography pattern Microservices maintain their original effectiveness.


First, we would like to inform you that this approach is not for everyone and its users need to upgrade their mindset before using it. As it works in an entirely different manner, a certain mindset shift is essential.

Secondly, the management process of this approach is a little bit difficult as business processes are spread all across the microservices. As each microservice is independent and has great autonomy, maintaining operations is very tough. The loosely coupled nature of this approach makes things more complex. 

The handling complexity is also way too high than what you will experience with orchestration. Every involved microservice is controlled by a specific logic and reacts differently to the incoming API message. Even if messages are coming from the same source, having different resources makes things utterly complex. The final outcome of this complexity is more failure risk. 

This approach also asks for more tools, which can be a little extensive for many. Along with Event Broker, you have to use service mesh and runtime DAPR as well to make this approach into action. 

Procuring and maintaining three tools are not doable options for every business. On the contrary, orchestration only requires one tool, an orchestrator. So, it has a wider approach. 


To automatically apply this approach and ensure things go smoothly, you can try choreography tools like Kafka, Amazon SQS, and RabbitMQ. They all are Event Brokers, which is the main tool for this approach. A service mesh like Istio and runtime system DAPR are also used for the choreography approach.

Choreography Vs Orchestration

Hybrid Approach

Both the above-mentioned approaches, Orchestration in Microservices and Choreography, are not flawless. This is why one has to find a middle path that has the maximum benefits of both approaches and the least possible limitation.

Gladly, there is one approach, and it’s the Hybrid approach. This approach features both asynchronous and synchronous factors. It features a fully centralized component that is based on the orchestration concept. This approach grants more extensive visibility over key workflows, which is not possible with the choreography approach.

But, this approach is also not flawless. Like the orchestration approach, a hybrid approach is also very dependent on the orchestrator, and if there is any error in this, the whole application will be affected severely. Making changes in the logic is also a very tedious job to do.


Choreography Vs Orchestration - So, Which One To Choose?

From this extensive analysis, we are able to deduce that both these approaches are mixed bags. They are good for many reasons and must be avoided for certain evident limitations. Now, which one should you pick?

Well, the clear answer to this question is what you want for your project. You need to figure out how the project implementation should go, what specific requirements are, what’s the final goal to be achieved, and which kind of precious resources you have.

Microservices choreography is recommended if you’re expecting your project to be highly scalable and have enough resources to deal with extreme complexity.

If you aim to have better control over every application aspect and plan a stable implementation, go with orchestration, as it makes the development highly measurable.


Anyone interested in using the services-based development approach will have a time when they have to do a detailed study of orchestration v/s choreography. Both are widely used approaches for Microservices architecture implementation and work distinctly.

Orchestration is coupled, and choreography is decoupled. Orchestration is easy to implement, while choreography is too complex. Choosing one out of these two is a taxing job as multiple factors should be kept in mind.

The article intended to make key differences between orchestration and choreography clear to future users. We hope that it succeeded. Microservices architecture is great but needs a deeper level of understanding of key concepts to reap maximum benefits. We have many more articles on Microservices. Do check them out.
