Very simplified insurance sales system made in a microservices architecture using .NET Core

ASCLAB .NET Core PoC - LAB Insurance Sales Portal

This is an example of a very simplified insurance sales system made in a microservice architecture using:

• .NET 7
• Entity Framework Core
• MediatR
• Marten
• Eureka
• Ocelot
• JWT Tokens
• RestEase
• RawRabbit
• NHibernate
• Polly
• NEST (ElasticSearch client)
• Dapper
• DynamicExpresso
• SignalR

Comprehensive guide describing the architecture, applied design patterns and technologies can be found on our blog:

• Part 1 The Plan
• Part 2 Shaping microservice internal architecture with CQRS and MediatR
• Part 3 Service Discovery with Eureka
• Part 4 Building API Gateways With Ocelot
• Part 5 Marten An Ideal Repository For Your Domain Aggregates
• Part 6 Real time server client communication with SignalR and RabbitMQ
• Part 7 Transactional Outbox with RabbitMQ

Business Case

We are going to build very simplified system for insurance agents to sell various kind of insurance products. Insurance agents will have to log in and system will present them with list of products they can sell. Agents will be able to view products and find a product appropriate for their customers. Then they can create an offer and system will calculate a price based on provided parameters.
Finally agent will be able to confirm the sale by converting offer to policy and printing pdf certificate.
Portal will also give them ability to search and view offer and policies.
Portal will also have some basic social network features like chat for agents.
Latest feature is a business dashboard that displays sales stats using ElasticSearch Aggregations and ChartJS.

Architecture overview

• Web - a VueJS Single Page Application that provides insurance agents ability to select appropriate product for their customers, calculate price, create an offer and conclude the sales process by converting offer to policy. This application also provides search and view functions for policies and offers. Frontend talks to backend services via agent-portal-gateway.

• Agent Portal API Gateway - is a special microservice whose main purpose it to hide complexity of the underlying back office services structure from client application. Usually we create a dedicated API gateway for each client app. In case in the future we add a Xamarin mobile app to our system, we will need to build a dedicated API gateway for it. API gateway provides also security barrier and does not allow unauthenticated request to be passed to backend services. Another popular usage of API gateways is content aggregation from multiple services.

• Auth Service - a service responsible for users authentication. Our security system will be based on JWT tokens. Once user identifies himself correctly, auth service issues a token that is further use to check user permission and available products.

• Chat Service - a service that uses SignalR to give agents ability to chat with each other.

• Payment Service - main responsibilities: create Policy Account, show Policy Account list, register in payments from bank statement file.
  This module is taking care of a managing policy accounts. Once the policy is created, an account is created in this service with expected money income. PaymentService also has an implementation of a scheduled process where CSV file with payments is imported and payments are assigned to policy accounts. This component shows asynchronous communication between services using RabbitMQ and ability to create background jobs. It also features accessing database using Dapper.

• Policy Service - creates offers, converts offers to insurance policies.
  In this service we demonstrated usage of CQRS pattern for better read/write operation isolation. This service demonstrates two ways of communication between services: synchronous REST based calls to PricingService through HTTP Client to get the price, and asynchronous event based using RabbitMQ to publish information about newly created policies. In this service we also access RDBMS using NHibernate.

• Policy Search Service - provides insurance policy search.
  This module listens for events from RabbitMQ, converts received DTOs to “read model” and indexes given model in ElasticSearch to provide advanced search capabilities.

• Pricing Service - a service responsible for calculation of price for given insurance product based on its parametrization.
  For each product a tariff should be defined. The tariff is a set of rules on the basis of which the price is calculated. DynamicExpresso was used to parse the rules. During the policy purchase process, the PolicyService connects with this service to calculate a price. Price is calculated based on user’s answers for defined questions.

• Product Service - simple insurance product catalog.
  It provides basic information about each insurance product and its parameters that can be customized while creating an offer for a customer.

• Document Service - this service uses JS Report to generate pdf certificates.

• Dashboard Service - Dashboard that presents sales statistics.
  Business dashboards that presents our agents sales results. Dashboard service subscribes to events of selling policies and index sales data in ElasticSearch. Then ElasticSearch aggregation framework is used to calculate sales stats like: total sales and number of policies per product per time period, sales per agent in given time period and sales timeline. Sales stats are nicely visualized using ChartJS.

Each business microservice has also .Api project (PaymentService.Api, PolicyService.Api etc.), where we defined commands, events, queries and operations and .Test project (PaymentService.Test, PolicyService.Test) with unit and integration tests.

Running with Docker

You must install Docker & Docker Compose before.
Scripts have been divided into two parts:

• infra.yml runs the necessary infrastructure.
• app.yml is used to run the application.

You can use scripts to build/run/stop/down all containers.

To run the whole solution:

./infra-run.sh
./app-run.sh

If ElasticSearch fails to start, try running sudo sysctl -w vm.max_map_count=262144 first

Once the application and infrastructure are started you can open http://localhost:8080 in your browser and see our welcome page. Once there you can use Account menu item to log into the system. Valid users and passwords can be found here. You can for example login as admin with password admin.

Manual running

Prerequisites

Install PostgreSQL version >= 10.0.

Install RabbitMQ.

Install Elasticsearch version >= 6.

Init databases

Windows

cd postgres
"PATH_TO_PSQL.EXE" --host "localhost" --port EXAMPLE_PORT --username "EXAMPLE_USER" --file "createdatabases.sql"

In my case this command looks like:

cd postgres
"C:\Program Files\PostgreSQL\9.6\bin\psql.exe" --host "localhost" --port 5432 --username "postgres" --file "createdatabases.sql"

Linux

sudo -i -u postgres
psql --host "localhost" --port 5432 --username "postgres" --file "PATH_TO_FILE/createdatabases.sql"

This script should create lab_user user and the following databases: lab_netmicro_payments, lab_netmicro_jobs, lab_netmicro_policy and lab_netmicro_pricing.

Run Eureka

Service registry and discovery tool for our project is Eureka. It is included in the project. In order to start it open terminal / command prompt.

cd eureka-server
./gradlew.[bat] bootRun

This should start Eureka and you should be able to go to http://localhost:8761/ and see Eureka management panel.

Build

Build all projects from command line without test:

Windows

cd scripts
build-without-tests.bat

Linux

cd scripts
./build-without-tests.sh

Build all projects from command with test:

Windows

cd scripts
build.bat

Linux

cd scripts
./build.sh

Run specific service

Go to folder with specific service (PolicyService, ProductService etc) and use dotnet run command.

Getting error when trying to run the application - configuration

Hi, This is not issue. I need help to running the application on my local machine after I have cloned it from git. I have windows 10 and Docker Desktop.

I have followed all the steps mentioned to configure the application and run it. I have installed PostgresSQL and ran the DbScripts to create the databases and users.
I have build the application without any errors.
But when I run "docker-compose -f app.yml up -d" command I am getting "ERROR: build path C:\Study\Projects\Microservice-poc\policy-service either does not exist, is not accessible, or is not a valid URL."

Where can I find the guide or document to run the application?

• use prepared env variables in docker-compose (all.yml)

Invalid app.yml docker compose

Hi, this is a really interesting application, and good explanations at https://altkomsoftware.pl/en/blog/building-microservices-on-net-core-1

But I'm trying to run docker-compose using app.yml file with no success. It seems that the paths to "build" docker are invalids. Ex.: build: ../policy-service, there is no such of path in aplication solution.

Can help me just to run the entire solution ?

Unable to run Vue application after running the docker compose.

Hi Team,

I am unable to view the UI for the application after running the infra and app run scipts.
On the service registry all the services are up and running but if I try to access the Vue application using the URLs mentioned in the .env file it is unable to connect to the localhost.
Could you explain the way to run the application??

How to build and launch all the project

Build agent sales stats module

Create a new microservice responsible for gathering agent sales stats. Stats will be updated based on events send from policy service. Each time a policy is sold / terminated we update agent sold policies data in elasticsearch.
We use elasticsearch aggregation framework to build complex queries like: sales per product in time, or sales distribution, top agents list etc.

Run dotnetcore-microservices on both arm64 and x86_64 platforms.

Hi team,

I have tried to deploy services by using docker-compose without any changes in any file but it is failing with some error on arm64 and x86 so I have modified the below files :

For Arm64: I have modified Web/Dockerfile

- RUN npm install 

+ RUN apk add --no-cache ffmpeg opus pixman cairo pango giflib ca-   certificates \ 

&& apk add --no-cache --virtual .build-deps python g++ make gcc .build-deps curl git pixman-dev cairo-dev pangomm-dev libjpeg-turbo-dev giflib-dev \ 

&& npm install 

- RUN dotnet test --verbosity:normal 

+ RUN RUN dotnet test '--logger:console;verbosity=minimal' --verbosity quiet –filter FooBar 

and Productservice/Dockerfile :

- RUN dotnet test --verbosity:normal 

+ RUN RUN dotnet test '--logger:console;verbosity=minimal' --verbosity quiet –filter FooBar 

For X86: I have modified the Productservices/Dockerfile

- RUN dotnet test --verbosity:normal 

+ RUN RUN dotnet test '--logger:console;verbosity=minimal' --verbosity quiet –filter FooBar 

And appsetting.json file, I have changed localhost to host.docker.internal

After the changes both the script ./infra-run.sh and ./app-run.sh are running successfully on both platforms but when I am trying to see all services Ui in the browser then it’s not opening there. Only the below interface is showing in the browser:

@wojteksuwala Could you please share your feedback regarding the same?

Unable to start Postgres from infra-run.sh file

While running infra-run. sh, its unable to start Postgres database and throws following error

Error: The database is uninitialized and the superuser password is not specified.

Fix:

Need to include environment POSTGRES_HOST_AUTH_METHOD=trust in infra.yml for postgres section

Invalid path for *.Api's in Service projects Dockerfile

For instance, in PaymentService project Dockerfile:

COPY PolicyService.Api/*.csproj ./PolicyService.Api/

is pointing to PolicyService.Api in current directory but its located in its parent directory and Docker throws a forbidden error.
I am new to Docker, so I am not sure whether this config is wrong or I'am missing something.

Upgrade to .net 5

node-sass dependency is obsolete

I figured out that node-sass dependency mentioned in web package is obsolete now.

I tried to change it to

"devDependencies": {
"@vue/cli-plugin-babel": "^3.0.0-rc.10",
"@vue/cli-plugin-eslint": "^3.0.0-rc.10",
"@vue/cli-service": "^3.0.0-rc.10",
"node-sass": "^4.14.0",
"sass-loader": "^7.0.3",
"vue-template-compiler": "^2.5.16"
},

then web-vue built successfully

services are not working properly.

@wojteksuwala

I have successfully deployed microservices on both arm64 and x86_64 platforms, and I am also working on load testing using Locust. But product, pricing, and policy search services are not working properly.
Initially, when I ran docker-compose it worked fine, but the next time when I ran docker-compose the price of an insurance policy is not visible or calculated after purchase. It only works if all the images created by Docker Compose are removed.
Could you please share your feedback regarding the same?
Also, it would be really helpful if you can confirm that this demo application work only once or if can it be used for load testing.

How to scale ChatService?

Hey.

So how are you going to scale ChatService with sending policy created notification to clients? The problem is the next - clients are connected to different instances of ChatService and messages should be routed to proper instance to be sent to necessary client. Do you know how to solve this problem nicely with SignalR+RabbitMQ (if you need to of course)?

Thanks.
