What you should know about a monolithic application Vs. microservices

The adoption of microservice architectures by organizations is generating not only good results, but also a better perception of their systems by companies. We will teach you the difference between a monolithic application and microservices.

In fact, according to data provided by O'Reilly, a large majority of companies (54%) indicate that such adoption has been “mainly successful”, while a 10% indicates that it has been “absolutely successful”.

But it is not only decision makers who understand the advantages of this phenomenon. The same employees show a clear tendency for this type of software development:

  • Almost a third of developer employees are migrating the majority of their systems (more than a 50%) to microservices architectures.
  • There is talk of a trend, as by the end of 2020, approximately 61% of respondents reported having been using microservices for more than a year.

Because of the above, you may wonder what is a monolithic application vs microservices, and which one should be implemented in your development processes. If you want to know more, find out below.

Importance of software architecture

The importance of architecture in software development, and specifically in application development, it is undeniable:

  • A correct architecture allows better communication between stakeholders: decision makers, outsourcing companies, on-site developers, part-time collaborators, and even clients.
  • Software architecture is a reflection of how the organization works. For example, does your company have a rather flexible and adaptable vision to the environment, or absolutely rigid?
  • Architecture is key in the early stages of application design. What will be the most difficult thing to correct in the event of eventualities? Also, is the design consistent with the mission and vision of the company?

Knowing these essentials will help you better understand the differences between monolithic and microservices applications.

The differences between a monolithic application vs microservices:

While an app microservices It is made up of various modules and components that communicate with each other (but without losing their degree of independence), monolithic applications stand out for grouping all the functions in a single large code.

In that sense, it can be said that the first is more innovative than the second. This is the main difference between both types of architecture.

Now, to better understand what a monolithic application is, it is worth dwelling on some of the key concepts that differentiate one from the other:

  • Efficiency. At the beginning, it was said that monolithic applications tended to be more efficient, since everything was agglomerated in the same code. However, advances in information technologies, and the speed of cloud and internet architectures (such as fiber optics), have allowed microservices codes to be deployed equally effectively.
  • Probability of errors. Being a linear development process, monolithic architecture tended to immediately show the possible bugs, which is why it was often preferred over microservices, which were supposedly more prone to code failures as they were more complex structures. But today, thanks to more agile methodologies and more elaborate QA Testing processes, it has been possible to considerably reduce errors between connected microservices.
  • Stiffness and flexibility. Regardless of the advancement in technology, stiffness is one of the main characteristics of monolithic applications, making them more difficult to upgrade. A microservices application tends to be more flexible, adaptable and multifunctional in front of all types of environments, also offering some autonomy to each of the development teams.

Amazon Lambda: Achieve Application Modernization with Microservices

In conclusion, it is possible to achieve a better application modernization by implementing architectures that allow you to be adaptable to a changing environment, such as those of microservices.

For example, Amazon Lambda, which is part of AWS (Amazon Web Services), is a cloud service that allows you to run microservices code and architectures without the need to manage on-premises servers. That is to say, it is a serverless technology that can positively impact the culture of your company.

For back-end application development, Amazon Lambda helps you integrate your processes with other cloud services, such as API Gateway and RDS, all without having to worry about managing servers.

In Codster we are an official AWS partner and experts in the implementation of serverless technologies, helping you develop a more agile culture through microservices architectures.
