Monolithic vs Microservices Comparison: Which is the Best Architecture?

With the challenges that come along with managing each individual service, it’s even more critical for teams to have observability solutions that scale with the growth of their business. The term monolith comes from an ancient representation of a huge rock. When we talk about software, monoliths are nothing but a large block of codes having multiple modules.

SOA evolved in order to deal with the problems in monolithic architecture and became popular in the early 2000s. In SOA, the large application is split up into multiple smaller services that are deployed independently. There used to be an Enterprise Service Bus where these services expose themselves and communicate with each other through it. Also, there was no guideline to have an independent database for each service. 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.

But the tool could benefit from more tailored results and better … With a large infrastructure migration with a lot of people involved, the business wants to know about the return on investment, said Mike Tria, Head of Platform at Atlassian. It’s very important to keep up communications with the executive team, stakeholders, customers, partners, and the rest of the R&D teams. Ensure they know what you’re doing, including expected benefits. The benefits of Vertigo include increased deployment speed, disaster recovery, reduced cost, and higher performance. This allows us to get to our target faster while delivering more incremental value to customers along the way.

If there are tight timelines and you need to roll out your project as soon as possible, a monolithic approach will satisfy your needs. In order to identify the root cause of the error, developers have to inspect each service log independently which consequently leads to workload increase. Handling cross-cutting concerns such as logging, metrics, service registration, externalized configuration, etc. in a microservices architecture is required to be done in every service. BMC works with 86% of the Forbes Global 50 and customers and partners around the world to create their future. This capability gives developers the freedom to develop and deploy services as needed, without having to wait on decisions concerning the entire application. Small teams that are working in parallel can iterate faster than larger teams.

Microservices architecture makes it easy to deploy your application with smaller changes. This regular and automatic deployment provides a much deeper relationship between your customers and stakeholders because you can quickly answer problems and opportunities. You’re not waiting for a blue moon anymore to deploy your application. Because there is only one application, the deployment pipeline needs to account only for that application’s needs. On the other hand, in a microservice architecture, you need to deploy each microservice that need various configuration because of different needs.

The use of smartphones, tablets and other mobile devices are on the rise and slowly overtaking desktop devices. Since the monolithic architecture relies on desktop devices, many engineers and developers will move away from it. Therefore, they will switch to other favorable architectures such as microservices. Typically, there are three or more divisions in developing a monolithic application. However, the database, client interface, and the server must be present.

  • It is really important not to allow your application to become a big ball of mud because it creates more risks to down your whole application with one tiny change.
  • Microservices are an architectural and organizational approach to software development where software is composed of small independent services that communicate over well-defined APIs.
  • IT teams need experience in microservices, DevOps, containers and Cloud.
  • It can be challenging to determine how different components relate to each other, who owns a particular software component, or how to avoid interfering with dependent components.
  • Microservices have a complex structure that consists of various heterogeneous services and databases.
  • It’s critical to carefully consider your options and do your own research before determining.

If your goal is to upgrade the application and add new features in the future, microservices can help scale out. Moreover, with the technology progress, you as a business owner may opt for advanced solutions for your customers and be on top of your competitors. With the microservices approach, you can start to use different technologies based on your business requirements. Since microservices interprocess communication requires APIs, their performance is slower and, thus, users may deal with bigger latency and a slower response time. In contrast to microservices, within monolithic architecture, all calls are local and the processing time is streamlined thanks to communication within a single service. All the above-mentioned parts are interconnected and depend on one another.

Microservice architecture pros

This relatively simple structure makes monoliths fast and easy to build and support. A monolithic application is built as a single unified unit while a microservices architecture is a collection of smaller, independently deployable services. Deciding how to modernize your legacy applications requires you to first understand the difference between monolithic and microservices architecture.

Microservices architecture structures an application as a collection of smaller independent services communicating via APIs. Each service has its own function, codebase, processes, lifecycle, and database. Traditional monolithic architectures are built around the concept of large applications that are self-contained, independent, and incorporate myriad capabilities. As developers move advantages of microservices over monolithic to microservice-centric designs, components are broken into independent services to be developed, deployed, and maintained separately. Shifting from monolith to microservices makes it easier to test, develop, and release innovative features more rapidly. If an organization primarily uses monolithic applications, then it’s more difficult for teams to develop distributed applications.

Each module in a microservices application has its own business logic, database, and often an individual tech stack that can be completely different from the rest of the system. As a result, you can deploy and scale microservices independently. All this provides great flexibility both for business and engineering teams. The selection of the architectural type depends on the organizational structure of your project. If your business is a startup with a small team of developers, a monolithic approach will be more suitable. But if your goal is to scale your business and you are looking for solutions to upgrade your product – microservices would be a perfect fit.

The whole application is built using different layers, a user interface layer, a business layer and a persistence layer. For some organizations, SOA architecture is a steppingstone to replace the monolith, providing a more flexible and agile environment. SOA services can be developed and utilized in a large environment, but they do not address specific needs of individual businesses that wish to address business processes within their purview. DevOps can be used to help an organization transition from SOA architecture to microservices to address specific needs. Ultimately, microservices architecture saves teams time, offers more granular modifications to each service and scales with the need of every individual service and interface as a whole. The easiest way to understand what microservices architecture does is to compare it to monolithic architecture.

Monoliths are more straightforward to test than microservices since only one code set exists. As a result, there are fewer components to check, and it is easier to keep track of bugs. However, all the microservices need to be tested independently to ensure that there are no issues with the code.

A developer can focus on one service or see how different independent services affect the application overall. In conclusion, microservice-oriented applications are undeniably popular among businesses because they address issues that monolithic application designs do not. However, the choice between microservices and monolithic architecture depends on your business models and goals. For example, Mr. A is working on a multifaceted application with his team that is spread across geographical boundaries. In such a situation, a microservices architecture is more cost-effective and manages to scale the application seamlessly. Also, as far as team distribution is concerned, a monolith system poses challenges as Mr. A’s teams are not located in specific functional areas.

Large monolith architectures are both difficult and expensive to scale because you need to scale the whole application. Thus, businesses that rely on monoliths don’t deploy that often (e.g., every day) due to the risk since you always deploy the whole application. Not deploying that often accumulates features, and it is harder to have a continuous delivery mindset. That alone is a common argument for moving away from a monolith. Jay leads product marketing for Dynatrace’s Applications and Microservices and Digital Experience portfolios.

While monoliths follow the traditional deployments, microservices have given the system architects a tough time designing the deployment strategy. Since monoliths have a three-tier architecture, they have always been deployed on web servers like Apache Tomcat, Oracle Weblogic, IBM Websphere, etc. This usually consists of three parts, the UI, the database, and the server-side application. The server-side application usually handles all the HTTP requests and executes the business logic. In monoliths, the server-side logic, the UI logic, the batch jobs, etc., are all bundled in a single EAR , WAR , or a JAR file. Fig 2.1 shows us a high-level representation of the Monolith Architecture.

Microservices cons

Tools like Docker should also be embraced at the local level. This helps in speeding up the operational tasks like setting up a local database, etc. ✔ An API Gateway was introduced to connect all the drivers to the passengers. The API Gateway internally connects all the microservices such as Passenger Management, Driver Management, Trip management, etc., through REST API calls.

However, in the end, you can have huge tables that include attributes and columns that aren’t needed in most cases. In addition, your transaction time to get data from the database can increase because of the cost of the join functions. When your service is small, the code is easier for developers to understand and maintain it. Each microservice can start a lot faster than a large monolith does. This makes developers more productive and speeds up deployment time.

Different microservices communicate via API endpoints/HTTP protocols, making it into a distributed system. Microservices are small deployable services that are modeled around complex applications. A microservice is nothing but a newer version of Service-Oriented Architecture .

Developer independence

Because if you build it right the first time, you will save time and headaches in the long run. Lack of standardization – Without a common platform, there can be a proliferation of languages, logging standards, and monitoring. Added organizational overhead – Teams need to add another level of communication and collaboration to coordinate updates and interfaces.
