Spring Boot

We are in the process of building a modern content platform to deliver our content through various channels. We decided to go with Microservices architecture as we wanted scale. Microservice architecture style is an approach to developing an application as a suite of small independently deployable services built around specific business capabilities. You can gain modularity, extensive parallelism and cost-effective scaling by deploying services across many distributed servers. Microservices modularity facilitates independent updates/deployments, and helps to avoid single point of failure, which can help prevent large-scale outages. We also decided to use Event Driven Architecture pattern which is a popular distributed asynchronous architecture pattern used to produce highly scalable applications. The event-driven architecture is made up of highly decoupled, single-purpose event processing components that asynchronously receive and process events.

To build our #Backend capabilities we decided to use the following: 1. #Microservices - Java with Spring Boot , Node.js with ExpressJS and Python with Flask 2. #Eventsourcingframework - Amazon Kinesis , Amazon Kinesis Firehose , Amazon SNS , Amazon SQS, AWS Lambda 3. #Data - Amazon RDS , Amazon DynamoDB , Amazon S3 , MongoDB Atlas

To build #Webapps we decided to use Angular 2 with RxJS

#Devops - GitHub , Travis CI , Terraform , Docker , Serverless

Vue.js vuex Quasar Framework PubNub Apache Cordova Spring Boot We built our phone app using apache cordova since it has plugins for all native mobile functionality that we needed , and it saved us time rather than maintaining separate native swift and android codebase. We used an upcoming framework called quasar that helped us bootstrap our cordova project in vue js , and also has a ton of built in vue components. In order to push data to our phone on the fly , we used pubnub. It was super easy to add in a few lines to code to do this. We would save data on the server , and use pubnub to communicate updates to all the clients. Another nifty feature offered by pubnub that we used was mobile notifications delivery. : you send data to pubnub who inturn forward it to apns or firebase depending on the payload. On the server side we used plain old spring boot application , and configured cross domain communication to allow requests from ://file domain. ( Corodva app is a bunch of web html files packaged as app ).

We also heavily used cordova plugins to talk to phone , eg. cordova-plugin-calendar and cordova-plugin-local-notification : The second one was used to generate notifications from within the app , when the app is already open but you are in a different screen and want user to be notified . If the app is not open native push notifications delivered through apns / firebase would show.

I am pretty happy with out decision . other than the fact that quasar framework got recently upgraded to v1 and some of the newer components that replace the older ones do not maintain the same look and feel , an example of that is linked below.

I use Spring-Boot because it almost let you get things done quickly for a JVM-target project, with auto configuration components and dependency management starters. It is almost perfectly tailored for microservices applications development with a single unit deployment artifact (JAR) along with support for Service Registry and Discovery, Circuit Breaker pattern...

Any third-party library or any back-end service would perfectly integrate well since Spring offers integration support for most of mainstream services, let it be a RDBMS service, a NoSQL database, a Message Broker...

Coming to day-to-day development, Spring-Boot enjoys a great community so you can get support, direction, focused guidance from almost everywhere.
