Monolithic systems are often used with legacy systems, but this software architecture has been in use especially for building simple programs and proof-of-concept applications.<\/p>\n

However, businesses these days increasingly seek flexible and scalable software solutions as applications become more complex. Approximately 63% of tech companies<\/a>, including industry giants such as Spotify and Amazon, have initiated their migration to microservices.<\/p>\n

Given this trend, many forward-thinking tech companies are considering to migrate from monolithic to microservices. However, to ensure a smooth migration, a clear and feasible strategy needs to be chalked out by understanding the differences between the two.<\/p>\n

Difference between Monolithic and Microservice Architecture<\/strong><\/h2>\n

A monolithic application is built as a unified unit, while a microservices architecture combines more minor, independently deployable services. Understanding its suitability depends on several factors.<\/p>\n

A monolithic architecture is a system where a universal codebase handles all operations, data storage, and migrating on-premise data to the cloud<\/a> and requesting processing. Typically, monoliths consist of a client-side user interface, a server-side application, and a database. The server-side application receives and processes requests, executes domain logic, returns data from the database, and presents it to the user interface of the requestor (client).<\/p>\n

On the other hand, microservices refer to a software architecture that contains multiple services responsible for specific operations. This is why microservice architecture is also known as service-oriented architecture (SOA).<\/p>\n

The following are some primary advantages of Microservices Architecture:<\/strong><\/h3>\n
    \n
  1. Enhanced Agility<\/strong>: The microservices architecture center promotes agile work practices by enabling small teams to deploy updates frequently. Microservices architecture breaks down a large, complex application into multiple small, independent services that can be developed, deployed, and scaled separately. This modular and flexible approach enhances agility and enables organizations to respond quickly to changing business needs. It streamlines the development process, allowing faster and more efficient software delivery.<\/li>\n
  2. Scalability on Demand<\/strong>: When a microservice nears its capacity limit, additional instances of that service can be swiftly deployed within the associated cluster, alleviating any performance bottlenecks. This is particularly valuable for multi-tenancy scenarios where customers are distributed across various instances, enhancing support for larger instance sizes.<\/li>\n
  3. Continuous Deployment<\/strong>: Microservices facilitate more frequent and rapid release cycles than the previous weekly update schedule. Now, updates can be pushed out approximately two to three times daily.<\/li>\n
  4. Improved Maintainability and Testability<\/strong>: Teams can experiment with new features and quickly revert if necessary. This simplifies code updates and accelerates the introduction of new functionalities. Additionally, it becomes simpler to isolate and rectify faults and bugs within individual services.<\/li>\n
  5. Independent Deployments<\/strong>: Microservices are self-contained units, as a result of which they allow a SaaS software development company<\/a> to swiftly and autonomously deploy specific features, which enhances development efficiency.<\/li>\n
  6. Technology Flexibility<\/strong>: Microservice architectures allow teams to choose the tools and technologies that best suit their needs, fostering innovation and adaptability.<\/li>\n
  7. High Reliability<\/strong>: Deploying changes for a particular service doesn’t jeopardize the overall application’s stability, ensuring that updates can be rolled out without the risk of bringing down the entire system.<\/li>\n<\/ol>\n

    5 Indispensable Steps to Migrate from Monolithic Applications to Microservice Architecture<\/strong><\/h2>\n

    Migrating from monolithic applications to microservice architecture is a transformational journey that empowers businesses to achieve greater agility, efficiency, and innovation. In the section below, we will walk you through the five indispensable steps to successfully navigate this migration and harness the full potential of microservices.<\/p>\n

    1. Project specification <\/strong><\/h3>\n

    Migrating from a monolithic to a microservices architecture requires a comprehensive project specification as a guiding blueprint. Following are some usage of this helpful document.<\/p>\n
