Скачать или смотреть Sequence diagram using AI chat: Microservices example

Welcome to Gleek's new video! Today, we will illustrate how microservices operate using a sequence diagram and Gleek AI chat.

Open the https://app.gleek.io/ in your web browser. Next, click the "New Diagram" button. If you have a premium subscription (https://gleek.io/pricing), you'll find the "Gleek chat" button at the bottom of the code field. Clicking this button will open a chat window where you can enter your prompt. For our purpose, we'll use: "Create a sequence diagram for microservices."

Once you send this prompt, Gleek's AI chat will begin crafting your requested diagram. The resulting sequence diagram will likely showcase several actors: User, API Gateway, Service A, Service B, and Logging Service. In this setup, the user initiates requests through an API Gateway, which directs tasks to various services, specifically, Service A and Service B. The API Gateway logs actions, and the Logging Service stores these logs. After storage, the API Gateway confirms log storage with the user. This diagram highlights the pivotal role of the API Gateway in client interactions within a microservices architecture.

To further enrich this sequence diagram, you can include more actors and interactions. For instance, let's illustrate how the user initiates an asynchronous request with the API Gateway. Simply enter the names of each actor and connect them with a labeled arrow saying "initiates asynchronous request."
Subsequently, the API Gateway forwards the request to a new actor, the 'Event Bus,' for later processing. In the Gleek App, you just need to input the following syntax in the code field: "API Gateway sends message to Event Bus."
Next, add a note above the API Gateway to emphasize the asynchronous communication. To do this, type "Asynchronous Communication," two dots, the word "note," two hyphens, and "API Gateway."
Then, we are going to illustrate that API Gateway acknowledges receipt of the request from the user. This acknowledgment indicates that the API Gateway has successfully received the user's request and is ready to process it further, ensuring a smooth and responsive interaction within the microservices architecture.


After acknowledging the asynchronous request, the API Gateway will exchange self-messages as it continues processing other requests. Since these messages go to and from the same object, Gleek will depict this with a looping arrow. We will create the same self-message for the 'User' actor. In this scenario, the User, after initiating a request and receiving a response, continues with its own processing of other requests.
Subsequently, the user, having successfully concluded its previous tasks, delivers yet another request to the API Gateway.
Eventually, we will introduce a new actor, "Service C," to showcase another possible interaction. To achieve this, type "API Gateway," a hyphen, "routes request" interaction and another hyphen. Then, press the plus key to activate the "Service C" and indicate that this object is currently in use.

Now, Service C will process the request and forward it to the API Gateway. Remove the activation bar from Service C by adding a minus symbol to the arrow. Finally, the API Gateway transmits the received response back to the User.

There you have it! Your comprehensive microservices sequence diagram is now complete. If you don't have access to Gleek Premium and Gleek AI chat, remember that you can still construct a Microservices Sequence diagram from scratch using the standard Gleek interface. Take a moment to explore the Gleek app, and please don't hesitate to share your thoughts in the comments.

Enjoy diagramming!
