How to rebuild monolithic application to micro services architecture?

Presentation Plan

1. Business context2. Technology3. Architecture4. Configuration management5. Monitoring6. Aggregating logs7. Deploying ( vagrant, docker )8. Modern documentation

Monolith

Application Domain

One entity – multiple identities

Same functionality – new architecture

Redirecting request

Url Rewriting

#Apache rewrite url, work for post requestRewriteEngine OnRewriteRule /generate http://reportservice.no/generate [P]

Needs

i

Embedded Container

Starting Service

./sbt>container:start[info] Started SelectChannelConnector@0.0.0.0:8090[success] Total time: 2 s

How microservice looks like?

Using via imported client

Many clients

Scala java - interoperability

Rest, json, http

Architecture

Architecture Evolve

Managing configuration

Configuration Service

Asking for configuration

Switching configuration dynamically

Services monitoring - status

Monitoring of dependencies

Graph visualization

Visualization of dependencies

Where is service with configuration?

etcd

Circuit Breaker

Hystrix

Implementation

Many services = many logs

One aggregation point

+ logstash

Configuration of Logstash

/_search?pretty&type=batch-staging

Amazon EC2

vagrant plugin install vagrant-aws

vagrant up --provider=aws

vagrant ssh <MACHINE NAME>

Technology stack

Proper documentation

Documentation

Generated json

Swagger-ui

Documentation as a client

Time for building microservices !
