“To be effective in fulfilling your goals, you must break them down into little tasks and then spend most of your time working on the task in front of you, instead of being overwhelmed by the enormity of the big goal.” ― Sunday Adelaja,

This may not be the ideology on which Microservices work, but it surely is the principle we follow while developing an App on the Microservices architecture.

Microservices are gaining popularity in the market as businesses work towards building complex and larger applications that can be segregated and handled as a compilation of smaller services. There have been an increasing number of people looking to redesign their traditional monolithic systems into a sequence of single independent microservices.

The natural question that comes to your mind is, Which is the most favorable language to be used while developing microservices for your next project?

You can use various technologies based on what best serves the purpose of your microservices. Let’s go through some of the programming languages that have the features and libraries, which will help you in getting your job done. But first, let’s begin by understanding Microservices.

What is Microservices Architecture?

The microservices architecture is a development methodology wherein you can fragment a single application into a series of smaller services, each executing in its own process and interacting with lightweight mechanisms. The microservices are developed around business capabilities, which are independently deployable with automated deployment mechanism. The microservices architecture needs a bare minimum of management of these services, built in different programming languages and employs different data storage technologies.

Reasons to Migrate to Microservices Architecture

5 Best Technologies To Build Microservices Architecture (1)

  • In a monolithic architecture, for a large application, it is hard to comprehend the complexity and sometimes it is tough to handle the code.
  • Applications require extensive manual testing in order to comprehend the impact of alterations.
  • Even for a small change, the entire application requires to be deployed again.
  • The heavy application with monolithic architecture can slow down the start-up time.

Benefits of Microservices

  • Easier Process Adoption – With a microservices architecture, new technology, and process adoption become simple.
  • Small Modules – As the application is broken into smaller chunks, it is easy for developers to develop and maintain.
  • Independent Scaling – Each module in microservices can scale independently through
    • X-axis scaling – by cloning with more memory Or CPU
    • Z-axis scaling – by size using sharding
  • DURS - Each service in microservices architecture can be independently DURS (Deployed, Updated, Replaced & Scaled)
  • Unaffected - Even the failure of a single module won’t affect the remaining part of applications.

Microservices guarantee increased the autonomy of development teams (speed to market), better fault isolation (reliability), re-usability and scalability.

Criteria for Choosing a Technology for Microservices

With microservices, you can build a reliable platform to extend the business while taking advantage of diversity in languages. Of course, you can use different technologies or languages for different services, but it does not mean it is effective. The microservices architecture comes with lots of operational overhead; hence adding a diverse programming language on top of that can exponentially raise that performance overhead. To reduce that, you should standardize your microservices technology stack by choosing the programming language based on your business needs. Here are the criteria to evaluate the programming language for microservices development:

  • Highly observable
  • Support for automation
  • Consumer-first approach
  • Independent deployment
  • Modelled around business domain
  • Decentralization of components
  • Support for continuous integration

Best Languages for Microservices

Microservices can be implemented with a horde of frameworks, versions, and tools. Java, Python, C++, Node JS, and .Net are few of them. Let us explore the languages that support microservices development in detail:

1. Java

Annotation syntax, which is easy to read, is the key factor that makes Java a great programming language for developing microservices. This feature makes Java Microservices much easier to develop when powered by Microservices frameworks. It offers more value in readability, particularly while working with complex systems. Java includes many opinions to support developing & deploying Java Microservices. It offers a user Interface, model components as well as connectivity to back-end resources, everything within the boundaries of a single, isolated and independently deployed apps.

In addition, many of Java EE standards are well suited for microservices applications like:

  • JAX-RS for APIs
  • JPA for data handling
  • CDI for dependency injection & lifecycle management

In addition, service discovery solutions like Consul, Netflix Eureka or Amalgam8 are effortless in connecting with Java Microservices.

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
  • Restlet – It supports developers to build better web APIs, which trail the REST architecture model
  • Spark – One of the best Java Microservices frameworks, supports creating web apps in Java 8 and Kotlin with less effort

2. Golang

If you want to enhance your existing project, the Golang can be a good choice for microservices development. Golang, also known as Go is popular for its concurrency and API support in terms of microservices architecture. With the Golang’s concurrency possibility, you can expect increased productivity of various machines and cores. It includes a powerful standard for developing web services. It is exclusively designed for creating large and complex applications. Go provides two impressive frameworks for microservices development:

  • GoMicro – It is an RPC framework, which comes with the advantages like Load balancing, server packages, PRC client, and message encoding.
  • Go Kit – The key difference of Go Kit from GoMirco is it needs to be imported into a binary package. Moreover, it is advanced for explicit dependencies, Domain-driven design, and declarative aspect compositions.

In addition to simple syntax, Go microservices architecture includes excellent testing support as it makes it simple to write robust tests as well as embed them flawlessly into workflows.

3. 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. Microservices Python ensures compatibility with legacy languages like ASP and PHP, which allows you to create web service front-ends to host Microservices.

With all these benefits, Microservices Python is considered to have an edge over other languages. Developers who implement Microservices Python use a RESTful API approach - a comprehensive way of utilizing web protocols & software to remotely manipulate objects. With this technology, it becomes easier to monitor the application since it is now broken into components. There is a broad range of Python microservices frameworks to choose from for your web application development. Some of them are as follows:

(Video) SAGA | Microservices Architecture Patterns | Tech Primers

  • Flask – Most popular Python Micro framework based on Jinja2 and Werkzeug
  • Falcom – Create smart proxies, cloud APIs and app back-ends
  • Bottle – Simple, lightweight and fast WSGI micro framework
  • Nameko – Best among the Python Microservices frameworks that allows developers to concentrate on application logic
  • CherryPy – Mature, Python object-oriented web framework

4. Node JS

Node JS became the go-to platform in the past few years for enterprises and startups who want to embrace microservices. Node JS is built with the V8 runtime; hence, microservices Node JS is going to be super-fast for Input-Output (IO) – bound tasks. Normally, Microservices Node JS is developed either using CPU-bound or IO-bound code. CPU-bound program demands many intensive calculations. Every time you run an IO call, Node JS doesn’t block the main-thread but submits the tasks to be executed by the internal IO daemon threads. Hence, Microservices Node JS gains popularity in terms of IO-bound tasks.

Stephen Commisso, senior software engineer of GoDaddy states that proper utilization of microservices and Node JS can help to handle the same load with just 10 % of the hardware.

Highly innovative enterprises accept that Microservices Node JS is an excellent combination for attaining increased productivity, high performance, satisfied developers and reduced costs.

5. .Net

ASP.Net, the .Net framework for web development makes it simple to build the APIs that becomes the microservices. It includes built-in support for building and deploying microservices using Docker containers. .Net comes with APIs that can simply consume microservices from any application you developed including desktop, mobile, web, gaming and more. If you have an application, you can start adopting .Net microservices without entirely revamping that application. The initial setup for .Net Docker images has already been done and available on Docker Hub, helping you to concentrate only on building your microservices.

The .Net microservices architecture allows a compilation of technologies between each service; as such, you can use .Net for a certain part of your app without implementing it everywhere. You can mix the .Net microservices with applications written in Java, Node JS, or any other languages. This allows a gradual migration to .Net core technology for new microservices that function in combination with other microservices and with services built with other technologies. Similarly, the .Net microservices can run on all leading cloud platforms.

The future of microservices leads us closer to serverless architecture; particularly, the promise of cost savings by only paying the amount of compute utilized is even more appealing. Microservices is an extensive concept that applies to churn apps, products or solutions to more granular and modular level. Keep in mind, it is not recommended to start microservices architecture from scratch since it is difficult to define the boundaries of each service at the beginning. There is no better way to choose the perfect technology for your microservices. Every technology decision depends on the tools you will use to develop other parts of your application. It also depends on the current knowledge of your development team.

In this blog, you will learn What is Microservices, differences between monolithic architecture and microservices, features, best practices with a use-case.

Features Of Microservice Architecture Advantages Of Microservice Architecture Best Practices To Design Microservices Companies. Inflexible – Monolithic applications cannot be built using different technologies Unreliable – Even if one feature of the system does not work, then the entire system does not work Unscalable – Applications cannot be scaled easily since each time the application needs to be updated, the complete system has to be rebuilt Blocks Continous Development – Many features of the applications cannot be built and deployed at the same time Slow Development – Development in monolithic applications take lot of time to be built since each and every feature has to be built one after the other Not Fit For Complex Applications – Features of complex applications have tightly coupled dependencies. Microservices is an architectural style that structures an application as a collection of small autonomous services, modeled around a business domain.. Different clients from different devices try to use different services like search, build, configure and other management capabilities All the services are separated based on their domains and functionalities and are further allotted to individual microservices These microservices have their own load balancer and execution environment to execute their functionalities & at the same time captures data in their own databases All the microservices communicate with each other through a stateless server which is either REST or Message Bus Microservices know their path of communication with the help of Service Discovery and perform operational capabilities such as automation, monitoring Then all the functionalities performed by microservices are communicated to clients via API Gateway All the internal points are connected from the API Gateway.. So the application as a whole can be easily built, altered, and scaled Componentization – Microservices are treated as independent components that can be easily replaced and upgraded Business Capabilities – Microservices are very simple and focus on a single capability Autonomy – Developers and teams can work independently of each other, thus increasing speed Continous Delivery – Allows frequent releases of software, through systematic automation of software creation, testing, and approval Responsibility – Microservices do not focus on applications as projects.. Independent Development – All microservices can be easily developed based on their individual functionality Independent Deployment – Based on their services, they can be individually deployed in any application Fault Isolation – Even if one service of the application does not work, the system still continues to function Mixed Technology Stack – Different languages and technologies can be used to build different services of the same application Granular Scaling – Individual components can scale as per need, there is no need to scale all components together. To avoid such challenges developers of this application decided to shift their application from a monolithic architecture to a newer architecture.. Refer to the diagram below to understand the architecture of shopping cart application. This means that developers don’t create a web microservice, a logic microservice, or a database microservice.. This type of architecture for the application not only helps the developers to overcome all the challenges faced with the previous architecture but also helps the shopping cart application to be built, deployed, and scale up easily.. If you wish to learn more on this subject and build your own applications, then check out our Microservices Architecture Training which comes with instructor-led live training and real-life project experience.

A scalable architecture in Reactjs is hard to define! This article explain React architecture best practices for building large react projects.

The poor performance of UI – Since the application has a single component, each change in state would result in the re-rendering of components.. So every time any component needs data, it’s the components that will serve as the single source of truth and help them with data..

Since every feature has a dedicated folder, the teams can work on them more effectively.. Need help in building a scalable React architecture for a large web application project?

This reference guide is the second in a four-part series about designing, building, and deploying microservices. This series describes the various elements of a microservices architecture. The series includes information about the benefits and drawbacks of the microservices architecture pattern, and how to apply it.

In figure 2, module Z is the service candidate that you want to extract from. the monolithic application.. Modules X and Y are dependent upon module Z.. Microservice modules X and Y use an IPC adapter in the monolithic application to. communicate with module Z through a REST API.. Therefore, when you modernize your monolithic application into. microservices, you must split the monolithic database based on the service. boundaries that you identify.. In monolithic applications, it's common for modules to access required data. from a different module through an SQL join to the other module's table.. A service uses an API call to get data from another service.. In figure 4, an order module uses an API call to get data from a product. module.. Another way to share data between two separate microservices is to replicate. data in the dependent service database.. In figure 5, the product service database is replicated to the order service. database.. Loose coupling : An asynchronous model splits the request–response. interaction into two separate messages, one for the request and another one. for the response.

There is a couple of microservices which implemented e-commerce modules over Catalog, Basket, Discount and Ordering microservices with NoSQL (MongoDB, Redis) and Relational databases (PostgreSQL, Sql Server) with communicating over gRPC and RabbitMQ Event Driven Communication and using Ocelot API Gateway.. ASP.NET Core Web API application REST API principles, CRUD operations MongoDB NoSQL database connection on docker containerization N-Layer implementation with Repository Pattern Swagger Open API implementation Dockerfile and docker-compose implementation. A single small team of developers can write and maintain a service.. Each service is a separate codebase, which can be managed by a small development team.. Services can be deployed independently.. A monolithic application has a single codebase that contains multiple modules.. Even with a small change in the application, the entire application must be deploy.. The challenge of testing: The large number of services deployed independently of each other makes the testing process extremely difficult.. A single small team of developers can write and maintain a service.Each service is a separate codebase, which can be managed by a small development team.. Services can be deployed independently.. A monolithic applications has large development organizations.Single code base created communication overhead.. When using Docker, a developer develops an application and packages it with its dependencies into a container image.. In order to run the application, the application’s image is instantiated to create a container, which will be running on the Docker host.Containers can be tested in a development local machines.

Learn all about component-based development and what are the best practices to follow to experience all its advantages to build a scalable frontend.

Component-based development, for one, is a modular approach that decomposes frontend monoliths and introduces benefits similar to that of microservices at the frontend.. In this article, you’ll develop a better understanding of what components are, how component teams function, and get actionable tips to adopt this fantastic web development strategy.. Component-based development is a software development strategy that uses loosely coupled components to build applications with emphasis on reusability.. This makes for a modular system where multiple teams can work simultaneously on individual components in the same interface.. Since component based development breaks down the system into independent components, the organization structure also works best with component teams.. If you still have to deal with a frontend monolith, now is the right time to start moving towards this modular approach.. Style guide, universal design guide, design language system, etc., are the different ways organizations lay down component development standards.. There are plenty of tools available to take care of specific functions throughout the development process.. Inspired by chemistry, Brad Frost introduced a practical approach to develop interfaces called Atomic Design.. Find ways to automate as many processes in component-based development.. Developers across teams end up writing similar code for different instances across the applications.. With a component-based software development process in place, components once created can be easily used across as many modules as needed.. It realized it needed some structure in its development approach.. As these components are further used across the different interfaces, the frontend appears highly consistent despite being made out of multiple independent components.. Component-based development allows for extending the benefits of a modular architecture to the frontend as well.

Discover when to use SaaS architecture over on-premise environments — and 10 best practices you can use for efficient SaaS architecture design.

In IaaS, a cloud computing service provides an organization access to computing resources such as servers, storage, and networking in the cloud.. In PaaS, a cloud service provider provides a cloud environment where an organization can develop, manage, and deliver its applications.. It is also known as a 'one to many' SaaS architecture.. Using a single app instance with several databases will make all users entering your environment access different databases simultaneously.. As a result, your application will scale faster, provide more resources to users concurrently, and feel more responsive.. Most organizations opt for a monolithic or on-premises architecture out of concern for losing control over their data.. RBAC is a data access control method that restricts different users from accessing and changing data that does not directly relate to their role in an organization.. One way to ensure your SaaS application puts users’ vendor lock-in concerns to rest is to make it supports standard integration APIs, so users are free to connect the solution with other SaaS or on-premises applications.. With a tool like CloudZero, you can track SaaS architecture costs by customers, products, teams, and units within your company.. Our cloud cost intelligence platform helps engineering and finance align on cloud costs and gain better visibility into their SaaS COGS, unit costs, and cost per customer.

What is SOA? SOA is an architectural pattern in computer software design. In this type of application, components provide services to other components via a communications protocol, typically over a n

SOA makes it easier for software components over various networks to work with each other.Web services that are built as per the SOA architecture tend to make web services more independent.. Transport : This component transports the service requests from the service consumer to the service provider and service responses from them to the service consumer.. SOAMicroservicesSOA model has a single data storage layer which shared by all of the services in that application.Microservices apps mostly dedicate a database or other type of storage to services that need it.Communication between different services in an SOA app uses simple and straight forward approaches.Microservices use complex APIs.Focused on maximizes application service reusability.More focused on decoupling.A systematic change requires modifying the monolith.A systematic change helps you to create a new service.DevOps and Continuous Delivery are becoming popular but yet not become mainstream.Strong emphasis on DevOps and Continuous DeliveryMonolithic in natureFull-stack in natureSupports multiple message protocols.Uses lightweight protocols like HTTP, REST, or Thrift APIs.It is designed to share resources across services.It is designed to host services that can function independently.Frequently involves component sharingTypically, it does not include component sharingInvolves sharing data storage between servicesEach service can have independent data storage.Better for large scale integrationsBetter for small and web-based applications.Communicates through an ESBCommunicate through an API layerRelies on sharing resourcesRelies on the bounded context for coupling.Less flexibility in deploymentQuick and easy deployment.The technology stack of SOA is lower compared to Microservice.Microservice technology stack could be very large.Business units are dependent.Business units are independent of each other.An SOA app comprised of two or three services.A Microservices app could have dozens of services.SOA applications are built to perform numerous business tasks.They are built to perform a single business task.Deployment is a time- consuming process.Deployment is straightforward and less time-consuming.Business logic components are stored inside of single service domain simple wire protocols(HTTP with XML JSON) API is driven with SDKs/Clients.Business logic can live across domains enterprise service bus like separate layers between services.Uses enterprise service bus (ESB) for communicationIt uses the less elaborate and straightforward messaging systemSoftware size is larger than any conventional softwareThe size of the Software is small in MicroservicesMulti-threaded with multiple overheads to handle I/OSingle-threaded mostly use with Event Loop features for non-locking I/O handlingA systematic change needed for modifying the monolithIn Microservices, systematic change is to create a new serviceFocus on maximizing application service reusability.Emphasis on decoupling.Common governance and standards.Relaxed governance, as is more focused on people’s collaboration and freedom of choice.The deployment process is time- consuming.Deployment is easy and less time-consuming.Less scalable architecture.Highly scalable architecture.. SOA requires high investment cost There is bigger overhead when a service interacts with another service this will increases the response time SOA service is not suitable for GUI (graphical user interface) applications that so it will become more complicated when the SOA needs heavy data exchange.. SOA involves sharing data storage between services while in Microservices, each service can have independent data storage.. SOA is designed to share resources across services while Microservices is designed to host services that can function independently.
