microservices horror stories

One horror story could be when the communication between microservices breaks down. For example, if there is a misconfiguration in the API calls. Suddenly, data stops flowing properly between services and the whole application starts to malfunction. The end - user experience becomes terrible as parts of the app stop working.

To write good user stories for microservices, you need to understand the microservice's functionality and the user's context. Focus on the value the user gets from the service and break it down into manageable chunks. Also, make sure the stories are testable and have acceptance criteria.

The microservice registration center is a basic component of the microservice architecture. It is used for automatic discovery and dynamic route of services. It can receive registration requests for microservice instances and store the instance information in the registration table. Through the registration center, service consumers can find and call the services they need according to the service name or other identification. The registration center can also achieve Load Balancer and fail over to ensure high service utilization. A microservice gateway is a component used in a separate or independent application in a microservice architecture. Its main function was to uniformly register and access the internal microservice component modules 'API interface capabilities to the gateway, and provide a unified interface service to the outside world. Through the gateway, the client only needs to access the exposed interface of the gateway, and there is no need to directly call the interface of each microservice. The gateway could also achieve security isolation, permission verification, monitoring, Load Balancer, and other functions to provide a better user experience and system performance. In the microservice architecture, the registrar and gateway were two independent components, each with different functions and application scenarios. The registration center was mainly used for automatic discovery and route of services, while the gateway was used for unified management and exposure of interface services. They play an important role in the microservice architecture, improving the system's flexibility, flexibility, and reliability. (Source: Doc3, Doc4, Doc7)

Eureka is a microservice registration center for communication between microservices. It consists of the Eureka server and the Eureka client. The Eureka server was responsible for the registration and discovery of services, while the Eureka client was responsible for interacting with service suppliers and service consumers. When a microservice starts, it will register its service information with the Eureka server and send a heartbeat regularly to keep the contract renewed. If the Eureka server does not receive a heartbeat within a certain period of time, the service will be removed from the service list. When a service consumer needs to call a service supplier, it will obtain the service supplier's address from the Eureka server and store the address in the local buffer so that it can be directly retrieved from the local buffer the next time it is called. Eureka was easy to use, stable, and reliable, so it was widely welcomed. It is a component of the Spring Cloud framework that implements service registration and discovery functions.

Sure. There was a case where a microservice handling data storage was not properly configured for backup. Due to a hardware failure in the server, all the data it was responsible for was lost. Since the microservice was isolated, the other parts of the application couldn't access the data either, causing major disruptions in the business operations.

Well, start by clearly defining the user and their goal. Then describe the actions they'll take and the expected outcome. Keep it simple and focused.

One horror story could be about a haunted house. In the story, a family moves into an old mansion. Strange noises start at night, like creaking floorboards and whispering voices. They soon discover that the previous owner was a witch who cursed the place.

One could be about a haunted house where strange noises and apparitions terrify the inhabitants. Another might involve a cursed object that brings misfortune to whoever possesses it. And there could be a story of a vengeful spirit that haunts a particular place due to a past injustice.

Perhaps there's a story about a cursed object. It might be a doll that seems to have a life of its own. In the '49 horror stories', this doll could cause misfortune to those around it. It moves when no one is looking and gives people nightmares just by being in the same room.

Well, in 'the dream team horror stories', it might be that the team had to deal with some unethical practices that turned into horror stories. Say, they were involved in a project where they found out the client was using their work for illegal activities. This discovery led to a lot of trouble for the team, including legal threats and a damaged public image.
