When you’re creating your first app, the first thing you need to ask is “Do I want to use a monolithic or microservices way of development?”. By answering this question, you can direct your IT team to start developing the app based on what’s best for the project. Learn the difference between both architectures in this quick guide.
Microservices vs Monolithic Architecture
Microservices vs Monolithic. Monolithic architecture means that the app is written as one piece of code where the components are made to work together. This architecture shares the same resources and space.
Microserve architecture means that the app is created out of independent, smaller applications capable of operating in their own memory space and scaling from each other through multiple separate machines.
Microservice architecture offers the following advantages:
- Performance: In the right circumstances, microservices have performance advantages based on how they’re organized. Users can isolate hot services and independently scale them of the rest of the app.
- Better Organization: Microservice architectures are better organized. Each microserver performs a specific task, and it isn’t concerned with the tasks of other components.
- Fewer Mistakes: Microservices created parallel development by creating a hard-to-cross boundary between separate parts of the system. With this system, you’ll find it hard to make a mistake: namely, connecting parts that should not be connected, and bringing too tightly those that have to be connected.
However here are the challenges that microservices present:
- Higher Operational Overhead: Microservices are deployed through their own containers or virtual machines, creating a proliferation of a VM wrangling work. These tasks are automated with container fleet management tools.
- Cross-cutting Concerns Through Each Service: As you’re creating a new microservice architecture, you’ll discover a lot of cross-cutting concerns that you didn’t anticipate during design time. You’ll have to incur the overhead of the separate modules for the cross-cutting concerns.
When Should You Start with a Monolithic Architecture
These are some scenarios that you should begin your project with monolithic architecture:
- Your Team is in its First Stage: You have a small team, around 2-5 members, and is unable to tackle a high-overhead and broader microservices architecture.
- You Don’t Have Microservices Experience: If your team don’t have any experience with a microservice unless you can explain “learning on the fly” at an earlier stage, it’s another sign you start with a monolith
- You’re Creating an Unproven Product or Proof of Application: Are you creating a new product in the market? If it’s a new idea, then it will evolve and change over time. So a monolith is important to allow for rapid product iteration. This applies to the proof of concept where the goal is to learn everything as possible, even if you throw it away.
Microservices is starting to become a popular service architecture. But the monolithic architecture is great when you’re starting off. It’s important to understand which one is the best for your project. Your own context, when evaluated with your own considerations, is the main key to deciding if you should start with monolith or microservices.
