microservices versioning

Over the past two years, the authors have been involved in the MicroServices team in overseas deliveries to enhance the scalability of the Finance system for customers. The author's team, 3 pairs of development (pair programming, 2 dev for pair) Support 11 services for customers, and the continuous deployment pipeline (CD pipeline) is an essential technical practice. This sharing author will share the ongoing deployment (CD) under the

? We can fully combine the advantages of both to implement a "dual gateway" in our ASP. NET Core application.Here is a diagram of an API gateway that I drew in the MicroServices architecture:Should most of the students can understand, I will explain briefly. Openresty Api Gateway Left-to-right HTTP requests are first received by DNS after receiving first-hand traffic after load balancing to the Openresty-based API Gataway Gateway cluster

Load balancing is an essential name for any high-availability, high-load system. In a large-scale distributed computing system, a service in a single case, it is difficult to deal with a variety of unexpected situations. Therefore, load balancing is a solution that allows the system to distribute traffic in the event of a performance bottleneck or in some of these states. In the Springcloud system, many of Netflix's best products have been added, one of which is the Ribbon for server-side load b

By using source code management tools such as TFVC or git, you can easily implement version operations such as fallback, compare, branch merge, and so on for software code. Do we also need versioning for software-dependent databases,

Quickly set up Feign in microservices and set up Feign in microservices Build a declarative REST client feign in the microservice architecture ].Feign is a declarative Web service client. This makes writing to the Web service client more convenient. Use Feign to create an interface and annotate it. It has support for pluggable comments, including Feign comments and JAX-RS comments. Spring Cloud supports Spr

You can subscribe to an interface and then publish implementations based on this interface. Let's look at the next example. I have an interface IAnimal and two implementations of cat and dog: Public interface IAnimal { string Name {get; set;} } public class Cat:ianimal {public string Name {get; set;} public string Meow {get; set;} } public class Dog:ianimal {public string Name {get; set;} public string Bark {get; set;} } I am able to subscribe to the IAnimal interface and

In recent years, the rapid development of micro-service architecture, Sparkpost is one of the early landing micro-service architecture companies, they found that the ground-floor micro-service process, not only need to consider service discovery, service registration, service call tracking chain and other architectural issues, but also need to pay attention to the micro-service API change management. One of the major features of MicroServices is the i

1. Introduction Database upgrades are often dragged to the "finalize phase" of the release task, which is often left at the end of the project or the last sprint before the release, which is not ideal because: Every time the software is released on a test environment, the database is often rebuilt, which means that testers lose their test data each time. If the duration of the project is longer, the upgrade scripts are sometimes delayed until a few months after the initial database changes oc

Tags: background database management tool Oracle ClientFor the traditional large-scale software products using relational database, the continuous development and maintenance of the background database can produce a large number of script files, how to make versioning more convenient for these script files, and how to quickly manage the permissions between the teams.

SOURCE : Huang ji csdn Blog: Why database versioning is necessaryPrefaceVersioning is common in the development process, but in the world of databases, version control is second-class or even third-class citizens. When many people develop a database management and application system at the same time, it is very important to use a reasonable method to monitor the changes of the tables, stored procedures and views in the database, every time the databas

Every time the need to evolve the database arises, whether structure (DDL) or reference data (DML), simply create a new mi Gration with a version number higher than the current one.
