Monolith vs Microservices: Pros and Cons of each Approach

  • by

Microservices, on the other hand, enable fast and easy problem tracing and troubleshooting. This allows teams to work on each service in parallel, making the development process faster and more efficient. As each service is independent, teams can choose the language and framework best suited to their needs. This also gives teams space to innovate and experiment without impacting the rest of the system.

  • In case of microservices-based architecture, you can scale just a few microservices and save your costs.
  • Since a microservices architecture consists of units that run independently, each service can be developed, updated, deployed, and scaled without affecting the other services.
  • Microservices applications consist of multiple distributed services that have weak connections and dependence.
  • Adopt and scale microservices without exceeding your budget and losing sight of your key business goals.
  • Microservices are often deployed on their own containers or virtual machines, which means lots of VM wrangling.

However, this disadvantage can’t beat the reliability of modular microservices architecture vs. monolithic applications that work as one undivided unit. In either case, it’s important to understand the trade-offs and carefully consider your specific needs before making a decision. It may also be helpful to consider using a hybrid approach that combines elements of both monolithic and microservices architecture to get the best of both worlds.

New products from Point A

Now that we’ve defined what a monolithic architecture is, what a microservices architecture is, and what their strengths and weaknesses are, we can decide which one suits your startup best. With the possibility of fast iterations and elimination of downtime of the app, users remain satisfied which impacts their retention and loyalty. Therefore, microservices ensure an increase in revenue thanks to efficient approaches toward process management. If any update is needed, it is not necessary to redeploy the whole system since each microservice is self-contained and each element can be scaled independently. Furthermore, this solution provides time and cost-efficiency. The monolithic application model was limited and inefficient.

Monoliths are less flexible since changes usually cover the entire system. As we mentioned a moment ago, microservices enable flexibility. Modular design allows to scale services unevenly depending on growing load, new technical requirements and business needs.

PLUS, a real-world migration example with business outcomes. It can also be a good choice when the system we need is to be relatively small and support one process. In the beginning, however, due to the ease of defining the requirements and the relatively low variety of services, the monolithic system was a better solution for them. It was efficient in a single process, and as it covered a fairly narrow domain that did not change over the years, the monolith worked great.

The right tools are essential when undergoing a microserivces migration. We didn’t migrate customers right away, but rather first invested and created tools for the migration, monolith vs microservices pros and cons knowing it was a marathon instead of a sprint. The most important tool we built was Microscope, our own internal service catalog to track all the microservices.

In the rapidly evolving digital ecosystem, the quicker you can move from an executive business decision to a product release, the better chances of success you have. Tell us more about your business needs to help us serve you better. The more detailed information will allow us to route your inquiry to the most appropriate person in our team. You might compare this architecture to parts of a car (e.g. windshield wipers, brakes, ventilation, etc.). Though many of these parts only work when powered by the car battery, their functions do not rely on each other and can continue even when other systems are removed/changed. The health check is more difficult, you have to monitor every service and aggregate logs as well as track the requests passing by each microservice to debug them properly.

Time to market

The team is incredibly honest, hard working and has been a source of new ideas and improvements. It is also important that by choosing a monolithic system, we condemn ourselves to one supplier — hardly anyone will take over such a system and take care of its maintenance or reconstruction. Technology companies then suggest switching to a new system or possibly refactoring.

With microservices, individuals of a team can work on individual modules. Each individual can build a module and deploy a module independently, thereby reducing the team’s operational friction and increasing the software delivery’s agility. Service modules in monolithic applications are tightly coupled. Business logic is tightly entangled and makes it difficult to isolate the application, and hence scalability becomes a challenge. The image above shows a distributed architecture, which is enabled by the implementation of microservices.

Methodological approaches, proper estimation of possibilities and risks, and understanding of business goals are the determinant criteria when adjusting your budget. Being a conventional approach, monolith architecture is mature enough for developers who are not required to possess specific skills as with microservices. Since all functions are unified, it is easier to manage them in one centralized directory.

Pros and cons of monolithic architecture

Kubernetes has many useful features, including automated rollouts and rollbacks, horizontal scaling, automatic storage orchestration, and more. The data used throughout the operations is modeled by another class that’s called from the service class. In this way, the data and application layers are separated, and the data can be changed without affecting the business logic. As microservices are treated as standalone entities, developer teams can find the best tools and technologies for each one.

monolith vs microservices pros and cons

In order to figure out which architecture will best suit your project, it is good to formulate situations when you need either monolith or microservices. Since monolithic apps are less complicated than microservices, their deployment is much faster and easier. Moreover, a monolithic approach is a traditional way of building applications, so developers are likely to possess all the needed capabilities. The most significant business benefit of the microservice-based approach over the monolithic one encompasses a substantial increase in efficiency and elimination of technical debt. However, like any solution, the monolithic and microservices approaches both have their benefits and drawbacks. Let’s shed a light on each architecture to understand which one is right for your project.

Pros and Cons of the Monolith Architecture

For a more detailed example of migrating a monolith app to microservices, check out this case study. This is an optional step that helps simplify migration to microservices, especially when the overall application is constantly changing. The so-called Big Bang rewrite is just as radical as it sounds.

Let’s establish what monolith and microservices architectures are. The microservices approach requires expertized developers who work according to Agile methodology and can make processes go smoothly and without downtime. Typically, the deployment of microservices results in additional units which lead to increased management and operational cost overheads. In order to incorporate new technology for a particular functionality, the application needs to be rewritten as a whole, which is time and cost-consuming. Such cross-cutting concerns as, for example, logging, error detection, or caching, affect the entire application.

Monolithic architecture use cases

Firstly, the client will need to make numerous requests just to load one product page. But in more complex solutions, the number of requests can go well into the hundreds. Public Internet and mobile networks are very likely to struggle with processing this amount of information. The microservice architecture allows developers to establish a hard boundary between certain parts of the system. This helps prevent unwanted entanglements – namely, connecting parts that shouldn’t be connected.

As all functions in monolithic apps are managed in one easy-to-access location, it is simpler to implement workflows that involve different components of the application. The following five tools can help you with deploying microservice applications. This is frequently used as a rule of thumb when organizing microservice teams and structuring microservice applications.

Monolith Architecture

Since all the elements are loosely coupled with each other, it increases the agility of the entire Software Development Life Cycle . Whether you consider migrating to microservices and need an experienced partner to help you plan, estimate and implement your project without risks. Or want to up your game and expand microservices by adding agile specialists to your team, you can leverage your experience and microservices development services. Monolithic architecture and microservices can be built with the same set of skills. However, microservices provide better flexibility when it comes to team composition, distribution of tasks and ownership. Microservices have a complex structure that consists of various heterogeneous services and databases.

Back End Server-side application which contains business logic written in java, PHP, Python or some other language. “Microservices” was premiered at an event for software architects in 2011, where the term was used to describe a style of architecture that many attendees were experimenting with at the time. In the case of monoliths, the communication calls are local. This leads to considerably lower latencies and thus improved performance. And then, even the conditions would determine which architecture does a better job. To even out things, we are going to discuss the performance, based purely on latency.
