Microservice Design Patterns

software-development-2-logo

The main characteristics of a microservices-based application are defined in Microservices, Monoliths, and NoOps.  They are functional decomposition or domain-driven design, well-defined interfaces, explicitly published interface, single responsibility principle, and potentially polyglot. Each service is fully autonomous and full-stack. Thus changing a service implementation has no impact to other services as they communicate using well-defined interfaces. There are several advantages of such an application, but its not ...

Microservices for Enterprises Part I

Technology is the foundation of differentiation whether you’re a large enterprise or the small startup. If businesses fail to embrace that fact, they run the risk of losing marketshare and ultimately headed for the history books. Providing new services, products, or innovative creativity to improve the experience of existing services all have a foundation in technology and IT can help ...

Microservices, Monoliths, and NoOps

devops-logo

Monolithic Applications A monolith application, in layman terms, is where entire functionality of the application is packaged together as a single unit or application. This unit could be JAR, WAR, EAR, or some other archive format, but its all integrated in a single unit. For example an online shopping website will typically consists of customer, product, catalog, checkout, and other features. Another example is of a movieplex. ...

Microservices, DevOps, and the cost of change?

devops-logo

As developers, we all love shiny new things. New technologies (Docker, Kubernetes), new languages (Golang, NodeJS), new hyped conversation starters (Microservices, DevOps, Cloud). And everyone seems to have an opinion about why you should do this architecture, or why you should use that language. At the end of the day, your employer is expecting you to deliver using a means ...

Microservices Maturity: Dogma or Dogfooding? You Decide…

software-development-2-logo

I’ve received some great feedback after posting my proposal for a microservice maturity/classification model last week, some positive, and some negative. Some private communications suggested that I may be getting caught up in the marketing hype, and several emails suggested that the microservice architecture really is just classical SOA re-invented. Other emails balanced out these comments by suggesting that microservices ...

Microservices Development with Scala, Spray, MongoDB, Docker and Ansible

scala-logo

This article tries to provide one possible approach to building microservices. We’ll use Scala as programming language. API will be RESTful JSON provided by Spray and Akka. MongoDB will be used as database. Once everything is done we’ll pack it all into a Docker container. Vagrant with Ansible will take care of our environment and configuration management needs. We’ll do ...

Microservices in the Enterprise: Friend or Foe?

java-interview-questions-answers

A micro approach to a macro problem? The microservice hype is everywhere, and although the industry can’t seem to agree on an exact definition, we are repeatedly told that moving away from a monolithic application to a Service-Oriented Architecture (SOA) consisting of small services is the correct way to build and evolve software systems. However, there is currently an absence ...

Good Microservices Architecture = Death of the Enterprise Service Bus (ESB)?

java-interview-questions-answers

These days, it seems like everybody is talking about microservices. You can read a lot about it in hundreds of articles and blog posts, but my recommended starting point would be this article by Martin Fowler, which initiated the huge discussion about this new architectural concept. This article is about the challenges, requirements and best practices for creating a good microservices architecture, and what ...
