How To Implement Spring Cloud Config Server In Microservices java Microservices Spring Cloud Spring Cloud Config Server by devs5003 - April 21, 2022May 3, 20267 In a Microservices architecture based Java application, we have multiple microservices in the form of multiple Spring Boot applications. Each Spring Boot application will have its separate configuration file, where we specify the values in the form of key - value pairs. If you used maven in your application, you must have guessed that we are talking about nothing but application.properties file. You might have noticed that some of the entries in each application's application.properties file are common, such as registering with Eureka server, Email, Security, JPA configurations etc. If we can keep these common entries in one central place and make them accessible by each application, it will make our development process easier. Therefore, How can we make a central
How To Implement API Gateway Spring Boot In Microservices API Gateway java Microservices Spring Boot Spring Cloud by devs5003 - April 8, 2022May 3, 20268 Microservices architecture offers us to deploy multiple services in different servers(hosts) in a private network. When a client request comes to microservices, it should get authenticated before the processing of request. Suppose we have 100 different services in a microservices based application. If client wants to interact with all of them, it will have to pass authentication 100 times. Reducing these many number of calls is one of the motivations to learn 'How To Implement API Gateway Spring Boot In Microservices'. If we have one service which takes care of authentication and also forward the request to concerned service, clients can get the response faster. Yes! We have such type of service which is responsible to do the same. It is
How to monitor Spring Boot Microservices using ELK Stack? java Elasticsearch ELK Stack Microservices Spring Boot by devs5003 - July 16, 2021May 2, 20263 While developing an application, we always incorporate a feature in our code that can direct us what went wrong if the application fails to run normally. This feature is nothing but logging. The more work you do with logging, the less work you have to do with fixing the application issue. Typically, we keep all logging information in a text format file, called a log file. This file captures all the details such as startup of a server, activities of all users, names of classes, methods, timestamp, occurred exceptions with stack trace etc. Moreover, it depends on us what all information we require in the log file. Sometimes, these log files become larger in size and finding the exact issue manually
How to Implement Distributed Tracing Logging using Sleuth Zipkin Microservices java Sleuth & Zipkin Spring Cloud by devs5003 - April 21, 2021May 20, 20261 In Microservices Architecture based Applications, there are multiple services which interact with each other. In order to serve a client request, one request may involve multiple microservices call to get the response. If any exception occurs or any latency issue appears during such calls, then how will we identify the root cause of the issue? Of course, we will make use of Spring Cloud Sleuth & Zipkin to support distributed logging & Tracing. Therefore, we are going to learn about 'How to implement Distributed Tracing Logging using Sleuth Zipkin Spring Boot' and related concepts accordingly. If we are working on a Standard application, we can implement logging by adding one log file to identify any exception or other issues like response
How to Implement Hystrix Circuit Breaker in Microservices Application? Hystrix Circuit Breaker java Microservices Spring Cloud by devs5003 - April 9, 2021November 14, 20254 Microservices based applications feature a huge amount of distributed components. These components interact with each other during the request processing. As the number of interactions over the network increases, the possibility of an abnormal behavior of a service may also increase. In that case, we need to have some handy techniques that can prevent or minimize this abnormal behavior. Here, we are talking about none other than a fault-tolerance mechanism. The circuit breaker is fault-tolerance technique that monitors and detects when a service is behaving abnormally. It temporarily rejects those calls until the service becomes healthy again. Netflix Hystrix is an open source library which provides this solution. Hence, we are going to learn 'How to implement Hystrix Circuit Breaker in
