Organizations and companies often have large monolithic applications that serve and support business requirements. Those applications are rigid and hard to deal with when it comes to maintenance and fulfilling changes required to shift or improve businesses quickly. A change in a monolithic application often requires the code-base to be rebuilt and recompiled, which may affect other services and components during the implementation and deployment of the changes; due to the high intercomponent dependency. The impact is proportionate to the size of the application. In addition, it often requires down-time to deploy a new version of the application, which may have impact on Time to Market.It is vital to measure the risks and understand the complexity in development and operation that result from transforming a monolithic application to microservices. Microservices requires organizational changes, such as breaking the development team into small teams per microservice and special skills in developing and operating microservices. Once all aspects are considered and the value of the transformation is realized, 21Style and its professionals can help and guide this transformation.- Application Analysis- Domain-Driven Design- Event Driven Architecture- Decoupled Components- Edge Services- Service MeshIntroducing, since 2014, modern Angular application based on microservices (mainly based on Quarkus and Dropwizard frameworks, some in Go language) in a complete and easy to use architecture with:- Kubernetes- Docker Swarm- Api Gateway (Apache ApiSix, WSO2, Tyk, HAProxy)- Keycloak (Identity Management/IDP)- Observability and APM (Prometheus)- KPI Management and TimeSeries Management (InfluxDB)- Neo4J (GraphDB) - MongoDB (DocumentDB)- Elastic Search (Search Engine)- RabbitMQ and Kafka (Message Bus)- Redis (cache)- WebSocket (STOMP)
