Enterprise application development and microservices

Hello everyone, Today we will see, Enterprise application development and microservices.

Introduction to microservices by putting the pieces together 

Once you’ve deployed a microservices web application to Kubernetes, you can expect it to look something like this:

A utilizer accesses the web application through an Ingress load-balancer provided by Kubernetes. It gets routed to the web application served by Node.js, which uses two other microservices on the back end, a Java authentication service and a Python image processing service.

This is just one example of how a microservice-based web application might look within a Kubernetes cluster.

Microservices  is an architectural style that structures an application as a collection of services that are,

Easier to Build and Maintain Apps

The main conception behind the microservices architecture is that some types of applications become more facile to build and maintain when they are broken down into more minuscule, composable pieces that collaborate. In other words, each component is developed discretely, and the application is then simply the sum of its constituent components. In a microservices architecture, each accommodation runs a unique process and customarily manages its own database. This not only provides development teams with a more decentralized approach to building software, but it additionally sanctions each accommodation to be deployed, reconstituted, redeployed, and managed independently.

Methodic Around Business Capabilities 

Microservice architectures invite teams to fixate on building business functionality in lieu of inscribing glue code. In other words, development teams are organized around business capabilities and not technologies. This betokens that accommodations are adaptable for use in multiple contexts. The same accommodation can be reused in more than one business process or over different business channels depending on the desideratum. Each team member is responsible for a particular service which results in building an astute, cross-functional team.

Ameliorate Productivity and velocity

The microservice architecture tackles the celerity issue of applications and its productivity by dividing it into diminutive components. In this way, these applications are developed and maintained at very expeditious haste. Different teams work independently without waiting for the other team to culminate their chunks of work. In this way, separate microservices are more facile to locate and modify. Quality assurance of this microservice architecture is very expeditious as the programs which are developed early are tested in lieu of waiting for all the programs to be consummated.

Flexibility in Utilizing Technologies and Scalability

As we ken that every microservice can be inscribed by utilizing a different technology. This feature has simplified the culling procedure of the technology staff for your concrete accommodations. Decoupled accommodations which are indited in different languages subsist tranquility by this microservice architecture. This is a very good answer to all of your quandaries if you are looking to scale up your business in the future. Microservices can integrate special features to your accommodations regardless of the interconnection of all the applications. Incipient features are facilely cranked by these microservices architecture.

Independent teams

Microservices are a benison for distributed teams. Carrying out the development of a massive monolith system can be intricate and messy if you’re working with divisions around the globe or elongated teams. Microservices grant the developers more independence to work autonomously and make technical decisions expeditiously in more minuscule groups. So, if the solution you’re developing is expected to be astronomically immense, be sure to consider the microservice architecture.

Major tools and technologies used in microservices.


Docker is an open-source containerization platform. Docker enables developers to package applications into containers—standardized executable components that amalgamate application source code with all the operating system (OS) libraries and dependencies required to run the code in any environment.

While developers can engender containers without Docker, Docker makes it more facile, simpler, and safer to build, deploy, and manage containers. It’s essentially a toolkit that enables developers to build, deploy, run, update, and stop containers utilizing simple commands and work-preserving automation.


Kubernetes is a popular open-source platform for container orchestration — that is, for the management of applications built out of multiple, largely self-contained runtimes called containers. Containers have become increasingly popular since the Docker containerization project launched, but astronomically immense, distributed containerized applications can become increasingly arduous to coordinate. By making containerized applications dramatically more facile to manage at scale, Kubernetes has become a key part of the container revolution.

3.Distributed tracing

On a microservice architecture, one of the major challenges is tracing. But, in today's situation, we have a bundle of technologies to surmount these challenges. Zipkin and ELK stack is one optimal solution to achieve distributed tracing.
Zipkin: Zipkin is a distributed tracing system. It avails accumulate timing data needed to troubleshoot latency quandaries in service architectures. Features include both the amassment and lookup of this data. If you have a trace ID in a log file, you can jump directly to it.

ELK stack: The ELK stack gives you the ability to aggregate logs from all your systems and applications, analyze these logs, and create visualizations for application and infrastructure monitoring, faster troubleshooting, security analytics, and more.

4.Best Languages/Frameworks for Microservices

Java: Annotation syntax, which is facile to read, is the key factor that makes Java a great programming language for developing microservices. This feature makes Java Microservices much more facile to develop when powered by Microservices frameworks.
There are several Frameworks for developing Microservices architecture. Some of the Java Microservices Frameworks are as follows: 
  • Spring Boot – This framework works on top of various languages for Aspect-Oriented programming, Inversion of Control, and others 
  • Dropwizard – This Java microservices framework assembles stable and mature libraries of Java into a simple and light-weight package 
  •  Spark – One of the best Java Microservices frameworks supports creating web apps in Java 8 and Kotlin with less effort
Python: Python is a high-level programming language that offers active support for integration with various technologies. Prototyping in Python is faster and easier when compared to other frameworks and languages. It includes powerful substitutes for heavy implementations like Django.
There is a broad range of Python microservices frameworks to choose from for your web application development. Some of them are as follows: 
  • Flask – Most popular Python Microframework based on Jinja2 and Werkzeug 
  • CherryPy – Mature, Python object-oriented web framework
Golang: Golang, additionally kenned as Go is popular for its concurrency and API support in terms of microservices architecture. With Golang’s concurrency possibility, you can expect incremented productivity of sundry machines and cores. It includes a puissant standard for developing web accommodations. It is exclusively designed for engendering sizably voluminous and intricate applications. Go provides two impressive frameworks for microservices development:
  • GoMicro 
  • Go Kit 
Node JS: Node JS is built with the V8 runtime; hence, microservices Node JS is going to be super-fast for Input-Output (IO) – bound tasks.

Before closing our session, Let us show you the architecture of the eCommerce application.

Microservice architecture is the coalescence of technologies. Based on the business requisites you can decide which implements and technologies are the best fit for your business.
