Web Frameworks, API-Driven Development, or Microservices – There’s More Than One Way To Modularize Your Monolith.

Valued Expertise Since 1991

Design – Architecture – Development – QA – Delivery – Deployment

The Big Question Is, “How Modular Should You Make Your Monolith?”

Understanding Your Options Helps Us Understand Your Requirements


2-Tier Web Framework

A traditional web framework is considered a 2-tier architecture (client side and server side) and is like a box of tinker toys and the fastest way to develop software. It’s a piece of software that supports the development of the front end (client-side) and back end (server-side) web application software, including web services, resources, and APIs, that run on the web. A web framework helps you with your code based on your task, simplifying the development process. This architecture and application framework have several advantages, including reliability and reduced errors, easier maintenance, and faster development. And often the deciding factor, and because of all these pre-developed pieces, it is a cheaper way to build. The disadvantage is that web frameworks are typically monolithic and have limitations when customization is required. A 2-tier architecture can also see a decrease in performance when many users rely on the application at the same time. These are important factors to be aware of when deciding on a direction.


3-Tier or Modular Architecture

The concept of modular architecture is not new, but the idea of simply breaking up a system into a few parts, or tiers and layers, can be overlooked with the hype of new trigger words, like microservices and API-Driven development. However, in all cases, understanding all the elements within your architecture is critical regardless of which format you select for your transformation. The key is to define where the monolith can be separated naturally. Of course, this is easier said than done, but doing so will be the first step no matter how far you take the modular architecture design unless you’re starting from scratch. If this direction is best for your company, identify natural breaks within the system that suit your purposes and lead to a good solution. You may be surprised that modifying your monolithic system into a few parts can make it look much smaller, more manageable, and more scalable, opening up development to smaller teams that are not so reliant on each other.

“Tier” vs. “Layer” β€” The terms “Tier” and “Layer” are often used interchangeably because they denote a physical separation within the software. However, there is an important difference. A “Layer” is a functional separation of code within the software, but layers are found within “Tiers.” For example, a 2-Tier architecture (or client-server architecture) is typically made up of one Tier holding the UI layer (known as the client-side/front end) and a second tier holding a business logic layer and a database layer (or server-side/back end). A “Tier,” although also a physical separation, contains one or more layers, like a Ukrainian nesting doll – the Tier is the outside container that holds all the “layers” together and allows for scalability in development.



In keeping with the modular design and development that has gripped development, micro-frontend is a front end development pattern that splits up the client-side applications into smaller units and helps with the routing of multiple front end applications. Similar to Microservices, and almost the same as 3-tier, it splits the applications up into sections (front end, back end, & Database) so multiple teams ( independently ) can work on different features and various aspects of the application at the same time, creating a more flexible, end-to-end, architecture.


API-Driven Architecture

Another form of modularity that has gained popularity is using an Application Programming Interface, or API, as the foundation of the architecture. Separating the front and back ends from the framework eliminates the dependencies between the two and allows you to connect and disconnect at will without impacting other areas. by uncoupling the front and back Agile/DevOps/CI/CD methodologies can thrive. No longer does one development team have to keep track of everything. Instead, smaller, more agile teams specializing in different technologies can be deployed. In addition, technologies that could not be used before can now be considered. Indeed, there are pros and cons to be aware of when moving to an API-Driven architecture from an existing monolith. For example, it is more expensive than a web framework model. However, when done correctly, the higher initial costs are offset by the benefits gained through flexibility and the ability to select technologies that may have a deeper pool of developers in a tight market.



Microservices is often referred to as the peak of modularity, and this may be the case. Still, microservices can also become so big and unwieldy that they create an issue in manageability and cost. For this reason, plan and document as you go along so this does not happen. The benefits are also similar to an API-Driven architecture, where smaller teams can work on different services without impacting other areas of the enterprise. Microservices does exactly what it says, taking tasks and turning them into micro-sized loosely coupled services connected by lightweight protocols (a loosely used term often used with APIs as well). We won’t detail the elements of the process here but know that multiple technologies can be used, and we can help you assess and determine the best way forward or assist your team with experienced on-demand co-development.

What Is The Difference Between an API & Protocol?

The terms API (Application Programming Interface) & Protocol can be confusing since both help two or more entities communicate with each other. However, protocols can allow for more flexibility since they require fewer dependencies on the code it is contacting for the response. On the other hand, protocols are less direct and require different forms of logic. Conversely, APIs are more library driven, binding the client end and server end together. The reason why you hear them interchangeably is that both connect a service user with a service provider.

Where Should You Start?

Assess Your Monolith With Great Detail – Tech to Business

Do a detailed assessment of your architecture and consider all aspects of the business.

The first thing to do is have someone in your organization who can candidly detail your current architecture and define a way forward that fits your business. The assessment should consider all aspects of your IT structure, technology, and enterprise expectations, including a roadmap for short-term adjustments and long-term goals. It should also outline current resources, required resources to succeed, and areas needing temporary injections of expertise. Breaking apart a monolith is a big step and requires detailed planning, but in the end, it affords a structure that can react to requests and changes much more quickly.

Monolithic to Modular - What's Best For Your Company

Once your detailed assessment is complete, your migration begins from a monolithic system to a lighter-weight collection of autonomous services.

As the modules are identified and the decoupling process begins, we help you decompose applications by business capabilities, subdomains, technology & services. During this time, consider refactoring outdated applications or services that do not have natural separation points but should be separated into more agile modules. This is also an excellent time to consider your workflows and eliminate manual processes with updated process automation and intelligent data collection.

Intertech supports your team in modularization, API, and microservices development.

You Are Not Limited In Your Technology Selection

We can provide an outside perspective when working with these technologies!

Microservices β€” .NET | .NET Core | ASP.NET

    Microservices β€” C# - Java - Go - Javascript - Python & More

  • Design – Architecture – Delivery & Development – QA Testing – Deployment
  • Frameworks – Modularization – API-Driven – Microservices
  • You can modularize or build out your microservices with almost any programming language. The bigger question comes in when you look at what is best for your company, which languages have the most robust library and tool sets, and the availability and learning curve for the selected technology, especially in this competitive IT market. Some of the languages we find most used for actual manageable business projects fall into the ones listed above. However, each has its pros and cons that must be considered.

    Listed below are a few languages we are often tasked to use when supporting our partners

    • Java – Java has a history and is the number 1 language used with microservices. It has a wide range of libraries and frameworks that can be relied upon, and it provides good access to support. However, something to consider is resource consumption issues can show up during execution. Make sure to weigh all pros and cons before selecting any technology.

    • C# – C# is one that we find used in many projects. Perfect for your .NET company, it works with other languages that support .NET, works with Visual Basic’s integrated development environment, many turn-key products, and has excellent documentation, not to mention the investment of Microsoft behind it, so it will continue to be supported and evolve well into the future. On the other hand, there is some dependency on the Windows platform though more cross-platform products are constantly being released, especially with Blazor and WebAssembly.

    • Go – We have recently seen more projects in Go/GoLang, though it is a young language. The pros and cons are that all components are open source, which can lead to security issues. The offset and the reason it is growing in popularity is that it’s a simple language. Along with its simplicity and ease of use, Go has several advantages, from a wide selection of utilities, super fast compilation, and easy integration with Kubernetes (which is developed with GoLang), so Dockers is a snap. This is a language to consider, but make sure you can find quality resources that know it – this can be a struggle, though it is changing all the time.

    • JavaScript – the second most used in a long list of options. Just in that statement, it tells you it is probably a good solution. One reason it’s a solid option is that Node.js uses an event-driven architecture, is fast, scalable, and easy to maintain. Unfortunately, Node.js’ performance can be reduced with heavy computational tasks, has no library support, and can have issues with its API. All in all, a definite language to consider with proven developer availability.

    • Python – Number three on that list in popularity for microservices is Python. Another general-purpose programming language that first appeared in 1991 and works on multiple platforms. A language to consider but worth noting is that speed can suffer due to it being an interpreted language that generates non-machine code on execution. Because of Dynamic typing, errors made during compilation may appear during runtime, leading to added work to resolve. Once again, it is well used and a solution you may be considering that works in many cases.

    • TypeScript, Haskell, Swift, Rust, & OthersThere are plenty of options for the languages you can choose, but there are also pros and cons that should be weighed, from the pool size of developers when hiring to security and support. However, once your modular architecture is in place, it is nice to know that a modular foundation, when done correctly, can allow you to select the right language for the right task and connect and disconnect at will without impacting the rest of the system.

    API Languages

  • Design – Architecture – Delivery & Development – QA Testing – Deployment
  • Frameworks – Modularization – API-Driven – Microservices
  • You can use almost any language for your APIs, but in most cases, you’ll select the one you’ve been using for other project areas, or your internal team is built around. However, pivoting to new technology is one thing. It is more important to determine the type of API you need, like Web, Local, or Program, and what purpose it will serve, from Remote Procedure Call (RPC), like JSON-RPC or XML-RPC, or SOAP or REST.

    We won’t go into each of these in detail, but know that if you are questioning any of these items, we can help sort it out and make sense of it all.

    Azure & AWS

    Microsoft Gold Partner β€” AWS Partner Network

  • Better For Remote Work – Access Files & Applications From Anywhere
  • Easier to Scale With Business Growth
  • Part Of A Proven System That Is Maintained & Updated For You
  • It is essential to understand the differences between the wide range of choices you have and the leaders of the pack; Azure, AWS, and GCP. For example, one of the key differences between Azure and AWS is how they deal with temporary storage. Azure is based on page and block storage “Blobs” for virtual memory and object storage. At the same time, AWS assigns temporary storage during the instance and then deletes the data when the instance is terminated. So much to consider. Let Intertech experts help you evaluate which is best for your long-term needs or help you integrate into the one already selected.

    On your next project, consider injecting proven full-time expertise backed by a network of colleagues with senior skills and an extensive knowledge base instead of a VMS-selected heads-down contractor that fits their price structure rather than what defines your reputation. Intertech focuses on its people and the value they bring to all our clients so you get it right the first time.
