They must also be willing to learn how to decompose application logic from a monolithic, static design to a collection of independent, but cooperating, microservices. One example of a course designed to help developers learn to “think in microservices” comes from IBM. Just like monolithic apps, modular software can be built with a wide range of coding languages and frameworks. Therefore, most of the rules forchoosing a tech stackapply here as well. That being the case, a microservices tech stack is effectively larger and much more versatile than that of traditional software.

“Monolith” in this sense describes the application as a single mass, but monoliths are developed with multiple files, modules, classes, etc. Modules are used as ways for developers to organize their code into useful and manageable pieces. Because these files are so tightly coupled, in practice, this modularity does not impact operations the same way as in microservices.

Although a monolithic application can be easier to work with initially, it becomes more challenging as the application evolves. Development tasks, such as isolating services for independent scaling or code maintainability, become more difficult. Each component in a microservices application can be scaled independently, making the entire process more cost and time effective. Since microservices applications are split up into smaller components and are better organized, they are easier to understand and manage. Developers can focus on specific services related to the business requirement they are trying to realize. There can be performance advantages with monolithic applications since all communication is local, which is faster than inter-process communication.

Applications Architecture

The architecture comes with a single system of development that allows for developing a whole application. An app has its inner structure, for sure, consisting of a database, customer-side interface, business logic, but it still remains an indivisible entity. Where applicable, it comes with a single executable binary as well. And microservices, so as user demands across countless services go up and down, they can scale the needed resources.

Furthermore, new technologies can be added more easily to each microservice as needed without affecting the entire application. A server-side application that handles and serves client-side requests, retrieves and stores data from/to the database and executes business logic. The service that is updated is deployed while the remaining system is still working. We do not need to take down and relaunch the entire system for one update. When it comes to deployment, monolithic systems are easier to deploy.

Making a small change in a single function requires compiling and testing the entire platform, which goes against the agile approach today’s developers favor. The Microservice architecture has a significant impact on the relationship between the application and the database. Instead of sharing a single database with other microservices, each microservice has its own database. It often results in duplication of some data, but having a database per microservice is essential if you want to benefit from this architecture, as it ensures loose coupling. Another advantage of having a separate database per microservice is that each microservice can use the type of database best suited for its needs. Each service offers a secure module boundary so that different services can be written in different programming languages.

Disadvantages Of The Microservices Architecture

On the other hand, Microservice architecture follows a modular approach to develop various applications. A Microservice Architecture comprises a set of small, independent, and autonomous modules which does various services. Every service should have the capability of independent implementation of its corresponding business units. But the Microservice architecture has a group of small independent units, which collectively works as a single application.

The application has a single tech stack.This means that the process of new technology implementation becomes extremely difficult. This leads to the ease of continuous development and the deployment of complex and huge applications. Development, deployment, operation, and scaling of every component of Microservices application are independent.

Microservice Vs Monolithic: Which Software Architecture Is Best?

First, in a monolithic application, all code must be written within the internal structure of a unified codebase. Well in software development, bridges, or networks, are vulnerable to malicious attacks that will threaten your application’s security. This involves setting up connections between modules and databases and actually doing the work of deploying these services independently. The weaknesses of microservice architecture are a bit harder to stand out. That said, you’ll want to be sure of whether microservices are right for you before employing the architecture in your business.

Furthermore, functions can now reside in a customer’s pocket or in some combination of cloud-based or corporate systems. As enterprises address these trends, they soon discover that the approach that they had been relying on — focusing on making the best use of expensive systems and networks — needs to change. The most significant costs are now staffing, power, and cooling. This is in addition to the evolution they made nearly two decades ago when their focus shifted from monolithic mainframe computing to distributed, X86-based midrange systems. Data synchronization also adds up to the complexity of running dispersed software as opposed to its locally-contained rival. Nevertheless, a monolithic architecture is innately more clear and transparent.

Codebases in microservices are broken into multiple code units, which makes them easy to manage and update. If you have more than one microservices that share a common element, re-write them so that they are different. Attempting to re-use the same logic can lead to unnecessary complications.

Disadvantages Of The Monolithic Architecture

The more services in a microservice architecture, the more complicated things will get. Each service in software-oriented architecture is tied to specific functionality. To add, services are self-contained and do not rely on external resources to function properly. With microservices, you’ll be able to deploy a highly efficient, easy-to-scale platform.

  • No longer are software monoliths able to meet the demands of today’s fast-paced competitive business landscape.
  • Knowing this, developers must thoroughly test each module, as it may be impossible to predict the outcome of any change–no matter how small–to the codebase.
  • This will, of course, require hiring a whole bunch of specialists to implement, as mentioned earlier.
  • Microservices is a complex model to adjust to and you cannot hold just any team responsible for its management.
  • He has written for more than 40 different publications on subjects ranging from technology, science, business, finance, and education.
  • Microservices don’t have the same resilience, fault tolerance, and isolation issues that plague monolith applications.

Monoliths have no future-proofing ability as you need to grow your business, provide more services to clients/customers, or increase back end operational agility. HiTechNectar’s analysis, and thorough research keeps business technology experts competent with the latest IT trends, issues and events. Basically, we thrive to generate Interest by publishing content on behalf of our resources. Since there is one codebase for the whole software, any minor change reflects on the entire software.


Because microservices are relatively new, there’s no universal definition that lays out what exactly a microservices architecture should look like. It can be both time consuming and costly for the organization to go through a complete audit process. Often, organizations continue investing in older applications much longer than is appropriate in the belief that they’re saving money.

Latency represents the amount of time data takes to travel between two destinations. Withjust above half of the enterprisesout there adopting the loosely coupled services approach, it’s a tough one to crack. VironIT is an international software development company established in 2004.

Microservices Vs Monolithic Architecture: A Detailed Comparison

A microservices approach and monolithic approach seem to be on opposite ends of a spectrum, but the idea of microservices is a response to the unwieldy mess that many monolith codebases have become. Deploying a monolith is the classic method of service development. In this model all of Monolithic vs microservices architectures the modules are interconnected in a single unit. This means that the entire code exists within a single codebase. In this type of development, scaling can be achieved by adding extra nodes. This is why monoliths are recommended for simple applications rather than more complicated ones.

You plan to build multiple independent teams that would work on different functions of your solution. If your team has no experience with microservices and has to learn “on the fly”, it’s another sign you should start with a monolith. To save you some clicks, we will explain the difference between monoliths and microservices using one picture https://globalcloudteam.com/ that represents them as food. Due to the microservice architecture, new app features can be released faster and more seamlessly. As each unit can be built independently, you can update system components without bringing down the whole application. Moreover, new features can be added as needed without waiting for the whole app to launch.

Your resources for development and maintenance will face the same fate as each individual service should have its own system of organization. Microservices are composed of isolated services which are packaged as a unit in a container along with all the service’s dependencies. Thus, each container or service calls for a computer processing unit and runtime environment.

However, the approach you choose should finally depend on the scope and specifics of your project. The right match will allow you to get your desired performance and get your project done with efficient use of your resources. In this approach, services are split into smaller parts which can be modified and developed independently.

Monolithic and microservices both have their advantages and disadvantages. But, we can’t say that microservices will work best for one or another project. Your business context is crucial while considering to start with monolith or microservices. Before adopting microservices, Walmart had an architecture for the internet of 2005. The company decided to re-platform its system in 2012, since it could not handle 6-million page views per minute and retain any kind of positive user experience.

Stackgeeks has experienced teams in many innovative technologies, frameworks, and libraries. This is to help bring your idea to life – and to help support it in the short term. While the program creates will run on a server, the servers hosts and manages completely by a third party who worries about all the patching, scaling, and load tasks. Docker containers help to isolate microservices but to allow those containers to share resources such as operating servers, libraries, or frameworks. These three parts are managed and served fromone large code basethat is then connected to thedatabase. Microservices work really well in organizations that have embraced Agile, DevOps, and CI/CD, and the decentralized decision-making culture that empowers small teams to move quickly.
