Springboot - Eureka

Springboot - Eureka - registry

Eureka is a registry that helps with service registration and discovery. It is a central component of the microservices ecosystem, allowing service instances to register themselves and facilitating service discovery.

Eureka Server is a RESTful service that maintains a registry of all service instances. It provides a way for services to register themselves and for clients to discover the location of a service.

Eureka Client is a library that interacts with the Eureka Server to register, deregister, and discover other services.

Eureka is a key component of the Spring Cloud Netflix project, which provides a set of tools for building microservices.

Following are the benefits of using Eureka in Spring Boot:

Service Discovery: Eureka helps in discovering services in a distributed system.
High Availability: Eureka provides high availability by maintaining a registry of all service instances.
Load Balancing: Eureka can be used to implement load balancing between service instances.
Failure Detection: Eureka can detect failures of service instances and remove them from the registry.
Client Side Caching: Eureka clients can cache the registry information to improve performance.

Here are some of the challenges you might face while using Eureka:

Complexity: Eureka can be complex to set up and configure.
Performance: Eureka can have a performance impact on your system.
Security: Eureka needs to be properly secured to prevent unauthorized access.

Overall, Eureka is a powerful tool that can help you build and manage microservices. However, it is important to be aware of the challenges involved in using it.

Daily Agile Scrum stand-up meeting guidelines

Followers of the Scrum method of project management will typically start their day with a " stand-up meeting ". In short, this is a quick daily meeting (30 minutes or less) where the participants share the answers to the three questions with each other: • What did I accomplish yesterday? • What will I do today? • What obstacles are impeding my progress? Some people are talkative and tend to wander off into Story Telling . Some people want to engage in Problem Solving immediately after hearing a problem. Meetings that take too long tend to have low energy and participants not directly related to a long discussion will tend to be distracted. These are the minimum number of questions that satisfy the goals of daily stand-ups. Other topics of discussion (e.g., design discussions, gossip, etc.) should be deferred until after the meeting. Here are few tips for running a smooth daily meeting: • Everyone should literally stand-up and no one should sit down ...

Empiricism (Scrum)

Empiricism asserts that knowledge comes from experience and making decisions based on what is observed. Pillars of Empiricism . Various practices exist to forecast progress, like burn-downs, burn-ups, or cumulative flows. While proven useful, these do not replace the importance of empiricism . In complex environments, what will happen is unknown. Only what has already happened may be used for forward-looking decision making. Each artifact contains a commitment to ensure it provides information that enhances transparency and focus against which progress can be measured: ● For the Product Backlog it is the Product Goal. ● For the Sprint Backlog it is the Sprint Goal. ● For the Increment it is the Definition of Done. These commitments exist to reinforce empiricism . The sum of the Increments is presented at the Sprint Review thus supporting empiricism .
