microservices

Let's say we have a User, Wallet REST microservices and an API gateway that glues things together. When Bob registers on our website, our API gateway needs to create a user through the User microservice and a wallet through the Wallet microservice. Now here are a few scenarios where things could go wrong: User Bob creation fails: that's OK, we just return an error message to the Bob. We're using SQL transactions so no one ever saw Bob in the system. Everything's good :) User Bob is created but before our Wallet can be created, our API gateway hard crashes. We now have a User with no wallet

I'm learning about microservices and I'm gonna build a project with a microservices architecture. The thing is, one of my team mates want to use one database for all services, sharing all tables so "data doesn't get repeated", each service would be built with different frameworks and languages like django and rails which use very different ORM standards. What would be the correct approach? Since I think working with one database would involve a lot of "hacking" the ORMs in order to make them work correctly. You are not likely to benefit from a Microservices architecture if all the services

I did some reading about microservices, and I'm little bit intrigued.Seems like it is interesting concept. But I wonder, what are advantages and disadvantages using microservices over monolithic architecture, and vice versa. When microservices suitable better, and where better to go with monolithic architecture. Kaj While I'm relatively new to the microservices world, I'll try to answer your question as complete as possible. When you use the microservices architecture, you will have increased decoupling and separation of concerns. Since you are litteraly splitting up your application. This

I'm having a hard time choosing a decent/secure authentication strategy for a microservice architecture. The only SO post I found on the topic is this one: Single Sign-On in Microservice Architecture My idea here is to have in each service (eg. authentication, messaging, notification, profile etc.) a unique reference to each user (quite logically then his user_id ) and the possibility to get the current user's id if logged in. From my researches, I see there are two possible strategies: 1. Shared architecture In this strategy, the authentication app is one service among other. But each service

I am trying to create a microservice architecture using Lumen / Laravel Passport . I have a multiple dockerized services, which all run as an separate Lumen app container in different VMs: API Gateway service (integrated with Laravel Passport for authentication & request validation to further proceeding) Chat Service (service for messaging/chat rooms) News Service … (and many other services) All of this services has it’s own separated Redis/MySQL databases e.t.c. In monolithic application, for example, there was a User table in the database, there was the relations between the tables and so

I am planning to use the Microservices architecture for the implementation of our website. I wanted to know if it is right to share databases between services or if it is preferable to have a separate database for each service. In this regard, can I consider having one common database for all services or does it violate the very essence of Microservice architecture ? Nitish Bhardwaj Microservices offers decoupling . You must break down your application into independent domains. Each domain can have a DB. In case other MS needs to access data owned by some other microservices, they have to

I'm getting an error trying to use the Docker functionality with my .NET core 2.0 project. I've been getting an error message saying Visual Studio Container Tools requires Docker to be running before building, debugging or running a containerized project. For more info, please see: http://aka.ms/DockerToolsTroubleshooting I followed the link, and upon realizing I have Windows 10 Home x64, and had to install Docker Toolbox, instead of Docker For Windows. Now it installed this executable called Docker Quickstart Terminal Is this the way one is supposed to start up that docker services? I have
