These services are adaptable for use in multiple contexts and can be reused in multiple business processes or over different channels. If any updates are needed in the system, developers must build and deploy the entire stack at once. A company transformation requires a senior executive sponsor who is accountable for results and is willing to enforce the necessary tradeoffs, said Sri Viswanath, CTO of Atlassian. This person should enable the organization to invest in new tools, systems, and processes to make improvements permanent. We have a service internally that allows us to spin up a new service on a particular stack and it precedes things like logging, monitoring, and cacheing.

  • To sum up, this type of architecture is used to create an indivisible unit without rigid boundaries between its constituents.
  • Often, organizations continue investing in older applications much longer than is appropriate in the belief that they’re saving money.
  • Get free online training on our container management software, Rancher, or continue your education with more advaned topics in the Kubernetes master classes.
  • When there are several units that communicate with each other, there is always a possibility of communication failures or issues.
  • Yes, they have certain issues but at the same time, monolithic applications have several benefits that are really hard to beat.
  • Operations staff must allow these functions to be hosted outside of the data centers they directly control.

Each service has its own scope and can be deployed, updated and scaled independently. There is little to no centralized management of these services. We moved 100K customers to the cloud, built a new platform along the way, transformed our culture, and ended up with new tools.

Microservices ArchitectureThe fundamental characteristic of microservices is their agnosticism toward technology. Using one or more network endpoints, microservices expose the business capabilities that they encapsulate. They also encapsulate data storage and retrieval, exposing data via well-defined interfaces, making them a form of a distributed system. Databases are therefore hidden inside the service boundary. As microservices are written in various frameworks and languages, they require substantial resources to accommodate each service requirement.

Microservices Security Design Patterns

End-to-end automatic testing doesn’t have to overcome any significant hurdles since there is no need to orchestrate different runtime environments and technologies. In this article, we will examine two approaches to choose the most relevant one for your needs. The team and product will expand in the future, implementing new specialists and technologies. The future product will be large and will have a lot of features and services.

High reliability – You can deploy changes for a specific service, without the threat of bringing down the entire application. Technology flexibility – Microservice architectures allow teams the freedom to select the tools they desire. Performance – In a centralized code base and repository, one API can often perform the same function that numerous APIs perform with microservices. Each microservice can use different technology based on the business requirements. It is very difficult to adopt any new technology which is well suited for a particular functionality as it affects the entire application, both in terms of time and cost.

Eventually, as services within the monolith demonstrate stability, they can be cleaved off into their own microservice, and removed from the monolith code. Since there are a number of independent services in a microservices application, testing the application is more complex compared to monolithic applications. Since all services in a microservices application can be built, deployed and updated independently, they have more flexibility versus using a monolithic architecture. Any issue in one microservice does not have an impact on the entire application and only affects that service itself. It is also much easier to add new features to a microservices application. When discussing microservices, it is also important to understand how they relate to containerization tools, such as Docker, and container orchestrators, such as Kubernetes.

Monolithic Vs Microservices Architecture: Modernizing Monolithic Apps And Databases For The Cloud

If your enterprise hasn’t adopted this approach, it would be wise to learn more about it. Suppliers like Rancher Labs have helped their clients safely make this journey and they may be able to help your organization. Unfortunately, that’s true – if there is a single issue with a component, the whole app will most probably fail simply because all components are interconnected. At the same time, you will need to determine which functions should be transitioned first to ensure your business continues to operate smoothly.

Monolithic vs microservices architectures

On the other hand, using microservices requires time and skills, and may be overly complex for some applications. When we moved from a small number of monolithic codebases to many more distributed systems and services powering our products, unintended complexity arose. We initially struggled to add new capabilities with the same velocity and confidence as we had done in the past.

How Do Microservices Benefit The Enterprise?

Simplified testing – Since a monolithic application is a single, centralized unit, end-to-end testing can be performed faster than with a distributed application. Skilled developers are required to work with microservices architecture, which can identify the microservices and manage their inter-communications. As above, microservices teams require enough in-house or outsourced skills in enough areas to develop each module / tech stack or to work with SaaS options for different modules. If your company has hundreds of microservices to manage, you need an orchestration tool to handle them. Such tools are responsible for deployment and load balancing, as well as for provisioning, scaling, and communication management.

Microservice vs Monolithic is the comparison between two standard approaches or architecture for software design and development. Microservice is a present trend in the software industry that utilized some of the latest technologies and programming languages for software development. Whereas monolithic is an industry-standard approach that is implemented for several years.


As the codebase grows, the architecture becomes more complex to understand. For example, new developers hopping onto a new project will struggle to comprehend the changes to the entire codebase — even with air-tight documentation. Once you know the best way to divide the monolith, it’s time to write the new microservices. Writing new programs is time-consuming and costly, so it’s important to do it right.

Monolithic vs microservices architectures

By standardizing on contracts expressed through business-oriented APIs, consumers are not impacted by changes in the implementation of the service. This allows service owners to change the implementation and modify the systems of record or service compositions — which may lie behind the interface and replace them without any downstream impact. A server-side application — which will handle HTTP requests, execute domain-specific logic, retrieve and update data from the database, and populate the HTML views to be sent to the browser.


And most importantly, start working on a modular monolith architecture to get the best of both worlds. Developers can still use a monolithic architecture to build lightweight applications that require no updates — a calculator application, for example. DZone shows that 73% of companies believe that microservices will become indispensable for building next-gen software applications. Making changes to one microservice allows you to redeploy it without disrupting other components.

Building another crucial piece of a small application or validating a business idea with a monolithic development cycle is relatively easy. However, growing enterprises can’t afford the risks of downtime, scalability hurdles, lack of agility, and other critical issues. Luckily, there is a way of avoiding the pitfalls of a monolithic approach to software development. This is the traditional approach to building applications that all of us have come across. Despite the fact that modern trends are forcing digital companies to increasingly make their choice in favor of a microservice architecture, the monolithic approach still has its advantages.

Microservice Vs Monolithic

In Monolithic architecture, external service calls to different modules are not required for small applications and this produces faster response time. However scaling large applications is usually difficult in such a framework. A microservices-based architecture allows for shorter development cycles, faster deployment, and adjustments. To deploy a monolithic application, it is necessary to collect some executable artifacts from the source code in the repository and transfer them to the server.

So for a car, one person puts the axles on the chassis, another fits the steering wheel, and so on. All workers on the line collaborate to get the car assembled, but they essentially work independently. Remember the old, “our systems are down, we can’t work right now? An example of this would be if your app focuses on collecting, aggregating, and analyzing data flow. While the system as a whole may live for a long time, its components—the containers—do not.

For many companies, it’s refactoring the monolithic application to create microservices and migrating it to the cloud. In this article, we’ll discuss how refactoring and migrating Monolithic vs microservices architectures work. For some situations, the monolithic software architecture works well. For instance, it suits startups that need to get a product up and running as soon as possible.

This also provides more opportunities to penetrate the system. Since the code is stored in one database, it can be easily shared across all the stages of the development. If an issue arises, you can reuse code from other applications to solve it. All the components have been combined into a single program, and all its functions are managed in one place. So, if any component is updated, the whole application has to be rewritten. Before starting a new project, you should understand what the application architecture is.

Independent units can scale horizontally or vertically, depending on your needs. Scaling isn’t limited by the capacity of each service and can be completely automated. You can isolate services that require a greater workload and scale them independently of the rest of the app.

So, common schedule delays can affect the release of the entire project. Some services can be created by a couple of developers; others require the collaboration of a large team. For improved productivity, you can form mobile and flexible teams. Now, let’s find out which one is best for your project—monolithic or microservices.

Monolithic applications lack proper modularity, and it has only a single code base. Monolithic application deployments follow a traditional approach, that is to release the application on a web server like Apache, Oracle, or IBM’s. Microservices can be deployed on on-premise servers, or in the cloud. Those microservices are now independent, capable of scaling as needed. Cleaving off the code which is most suited for scaling makes a good first microservice candidate. Individual teams can then be assigned to manage those microservices with dramatically less difficulty, and better efficiency.
