This blog will clear your understanding of how developers use microservices to scale their applications according to their need. This blog is a foundation for Microservice Certification Training.In this blog, you will learn about the following:Why Micr oservices?What Is Microservices?Features Of Microservice ArchitectureAdvantages Of Microservice ArchitectureBest Practices To Design MicroservicesCompanies Using MicroservicesWhy Microservices?Now, before I tell you aboutmicroservices, lets see the architecturethat prevailed before microservicesi.e. the Monolithic Architecture.In layman terms, you can say that its similar to a big container wherein all the software components of an application are assembled together and tightly packaged.Listed down are the challenges of Monolithic Architecture:Figure 1: What Is Microservices Challenges of Monolithic ArchitectureInflexible Monolithic applications cannot be built using different technologiesUnreliable Even if one feature of the system does not work, then the entire system does not workUnscalable Applications cannot be scaled easily since each time the application needs to be updated, the complete system has to be rebuiltBlocks Continous Development Many features of the applicatio ns cannot be built and deployed at the same timeSlow Development Development in monolithic applications take lot of time to be built since each and every feature has to be built one after the otherNot Fit For Complex Applications Features of complex applications have tightly coupled dependenciesThe above challenges were the main reasons that led to the evolution of microservices.What Is Microservices?Microservices, aka Microservice Architecture, is an architectural style that structures an application as a collection of small autonomous services, modeled around a business domain.Figure 2: What Is Microservices Microservices RepresentationIn Microservice Architecture, each service is self-contained and implements a single business capability.Differences Between Traditional Architecture and MicroservicesConsider an E-commerce application as a use-case to understand the difference between both of them.Figure 3: What Is Microservices Differences Between Monolithic Architecture and Mi croservicesThe main difference we observe in the above diagram is that all the features initially were under a single instance sharing a single database. But then, with microservices, each feature was allotted a different microservice, handling their own data,and performing different functionalities. Want to learn more about Microservices? Learn Now Now, let us understand more about microservices by looking at its architecture. Refer the diagram below:Microservice ArchitectureFigure 4: What Is Microservices Microservice ArchitectureDifferent clients from different devices try to use different services like search, build, configureand other managementcapabilitiesAll the services are separatedbased on theirdomains and functionalities and are further allotted to individual microservicesThese microservices have their own load balancer and execution environment to execute their functionalities at the same time captures data in their own databasesAll the microservices communicate with each other through a stateless server which is either REST or Message BusMicroservices know their path of communication with the help of Service Discovery andperform operational capabilities such as automation, monitoringThen all the functionalities performed by microservices are communicated to clients viaAPI GatewayAll the internal points are connected from the API Gateway. So, anybody who connects to the API Gateway automatically gets connected to the complete systemNow, let us learn more about microservices by looking at its features.Microservices FeaturesFigure 5: What Is Microservices Features Of MicroservicesDecoupling Services within a system are largely decoupled. So the application as a whole can be easily built, altered, and scaledComponentization Microservices are treated as independent components that can be easily replaced and upgradedBusiness Capabilities Microservices are very simple and focus on a single capabilityAutonomy Developers and teams can work independ ently of each other, thus increasing speedContinous Delivery Allows frequent releases of software, through systematic automation of software creation, testing, and approvalResponsibility Microservices do not focus on applications as projects.Instead, they treat applications as products for which they are responsibleDecentralized Governance The focus is on using the right tool for the right job. That means there is no standardized pattern or any technology pattern. Developers have the freedom to choose the best useful tools to solve their problemsAgility Microservices support agile development. Any new feature can be quickly developed and discarded againAdvantages Of MicroservicesFigure 6: What Is Microservices Advantages Of MicroservicesIndependent Development All microservices can be easily developed based on their individual functionalityIndependent Deployment Based on their services, they can be individually deployed in any applicationFault Isolation Even if one service o f the application does not work, the system still continues to functionMixed Technology Stack Different languages and technologies can be used to build different services of the same applicationGranular Scaling Individual components can scale as per need, there is no need to scale all components togetherSubscribe to our youtube channel to get new updates..! Best Practices To Design MicroservicesIn todays world, complexity has managed to creep into products. Microservice architecture promises to keep teams scaling and function better.The following are the best practices to design microservices:Figure 7: What Is Microservices Best Practices To Design MicroservicesNow, let us look at a use-case to get a better understanding of microservices.Use-Case: Shopping Cart ApplicationLets take a classic use case of a shopping cart application.When you open a shopping cart application, all you see is just a website. But, behind the scenes, the shopping cart application has a service for accep ting payments, a service for customer services and so on.Assume that developers of this application have created it in a monolithic framework.Refer to the diagram below:Figure 8: What Is Microservices Monolithic Framework Of Shopping Cart ApplicationSo, all the features are put together in a single code base and are under a single underlying database.Now, lets suppose that there is a new brand coming up in the market and developers want to put all the details of the upcoming brand in this application.Then, they not only have to rework on the service for new labels, but they also have to reframe the complete system and deploy it accordingly.To avoid such challenges developers of this application decided to shift their application from a monolithic architecture to microservices.Refer to the diagram below to understand the microservices architecture of shopping cart applicationFigure 9: What Is Microservices Microservice Architecture Of Shopping Cart ApplicationThis means that develo pers dont create a web microservice, a logic microservice, or a database microservice. Instead, they create separate microservices for search, recommendations, customer services and so on.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.Companies using MicroservicesThere is a long list of companies using Microservices to build applications, these are just to name a few:Figure 10: What Is Microservices Companies Using MicroservicesIf you wish to learn Microservices and build your own applications, then check out our Microservices Architecture Trainingwhichcomes with instructor-led live training and real-life project experience.This training will help you understand Microservices in depth and help you achieve mastery over the subject.
