Differences between a monolithic and microservices architecture

Past, present and future. Monolithic architecture vs microservices

In 2009, Netflix faced major growth challenges as its monolithic infrastructure was unable to meet the demand of its exponentially growing users.

So, they decided to migrate their platform to a microservices architecture, becoming one of the first high-profile companies to successfully migrate to a cloud-based microservices architecture.

Today, Netflix has more than a thousand microservices that manage and support separate parts of the platform, and has become responsible for 15% of the world’s internet traffic.

Basic differences between both architectures

A monolithic architecture consists of traditional software development built in a single block. In this model, all components are interconnected and deployed as a single entity. A monolithic architecture runs all processes as a single service, meaning that if you experience a spike in demand, the entire architecture must be scaled, limiting experimentation and making it difficult to implement new ideas.

In contrast, microservices are an architectural approach that composes software into independent services, each performing a single function and communicating with the rest through a well-defined interface. Running independently, each service can be updated, modified or scaled based on demand needs.

According to a study by Mordor Intelligence, the cloud microservices market is expected to grow from USD 1.3 billion in 2023 to USD 3.72 billion by 2028, at a CAGR of 22.8%.

Innovation capacity

If you have read our section “Eureka By Calímaco” you will have seen some ideas to improve the retention and participation of your users. But… Does your platform allow you to develop them?

Implementing innovative strategies and working on the retention and motivation of your casino users is essential to improve your casino’s KPIs. A microservices architecture allows new ideas to be implemented in an agile way, since if one component fails, the entire system is not compromised. This is crucial in the online casino industry, where a downtime on the website leads to a large loss of income and a decrease in user confidence.

Agility in processes

Microservices foster an organization of small, interdependent teams that take ownership of services, which are empowered to work independently and quickly, shortening development cycle times.

Imagine there is a problem with a game provider. A monolithic architecture would imply that, to solve it, all computers would have to be affected, which would greatly slow down processes and multiply the chances of experiencing website crashes.

However, this same problem with a microservices architecture could be solved in an isolated, fast and effective way.

Security considerations

Microservices security is crucial for several reasons: It prevents data breaches, protects system integrity, supports innovation, and ensures customer trust.

By working with microservices, you reduce the risk of a security breach affecting the entire system. In addition, it allows implementing specific and stricter security protocols for critical services, such as those that handle financial transactions.

Do you know the principle of least privilege? Microservices can be designed to operate with the minimum level of privileges necessary to perform their function, which limits the scope of what an attacker can do if they manage to compromise a service. Unlike monolithic systems, which can be at greater risk if a part of the system is compromised, since they operate with a broader level of privilege.

Summary of differences: Monolithic vs microservices architecture

Category

Monolithic architecture

Microservices architecture

Design

Unique code base

Independent software components with autonomous functionalities

Developmet

More complex to mantain

Easier to manage and mantain over time

Implementation

The entire application is deployed as a single entity

Each microservice requires an individual containerized deployment

Modification

Small changes pose greater risks, since they affect the entire code base

Easy to modify individual services without affecting the entire application

Growth

The entire application must be scaled, even if only certain areas experience increased demand

Ability to scale independent microservices, saving scaling overhead costs
