Microservices vs Monolithic Architecture: Which Approach is Suitable for a Start Up?

Microservices vs Monolithic Architecture: Which Approach is Suitable for a Start Up?
mobile app development company
Monolithic Architecture is a traditional approach in which the entire app is integrated into a single unified model. The prime objective is to interconnect all features making them co-dependent on each other. This model may sound simple, but creates roadblocks in handling bigger and more complex projects.
Microservices architecture, on the other hand, splits an app into smaller services that are interconnected and interact with each other with the help of APIs. Every microservice is independent, loosely coupled, and possesses a distinct hexagonal architecture comprising of business logic and different adapters. Here, each service is a separate codebase, has its own database, and can be deployed independently. This approach has gained momentum these days as modern-day businesses expect more agility in their operations. Some renowned brands using the microservices approach are Uber, Twitter, AWS, Netflix, and Spotify.
This post explores Monolithic and Microservices architecture in detail, outlines their differences and provides suggestions based on specific project requirements. A quick read will help you to pick the best-suited approach for your upcoming software development project.

Monolithic Architecture: Strengths & Weaknesses

Monolithic apps perform speedily at the initial stages as they use local calls in place of API calls throughout the entire network. But, this speed reduces with the expansion of the app. A monolithic app, being a single solution, rather than a set of separate apps, is easily manageable, involve much lower development cost, and encounter very few cross-cutting issues initially.
When the codebase of a monolithic app becomes huge, the IDE slows down, adversely affecting the developers’ productivity. Moreover, it’s challenging to scale the app, and modifying the programming language or framework that hampers the app’s functioning. Also, it’s pretty expensive to migrate to different technology in situations where monolithic architecture is used.

Microservices Architecture: Strengths & Weaknesses

Microservice architectures are well organized – each microservice is responsible for carrying out a particular task, without being concerned about the tasks carried out by the other components. And, since such services are decoupled, they can be effortlessly reconfigured and recomposed to fulfill the needs of various microservice applications. For instance, microservices can serve public API as well as web clients.
Each microservice can be written employing a different technology; for instance, one microservice can be handled by Java developers while the other can involve DotNet developers. Thus, you have the flexibility to choose a particular technology for catering to specific business requirements without having to lock other services with that technology. This helps in optimizing the performance of crucial functions.
Microservices allows you to auto-scale an application as per the load on the app, promises speedier deployment, and eases out rolling updates as there aren’t any dependencies between the services. With this type of architecture, you can execute parallel development by setting up boundaries between various parts of the system; these boundaries are difficult to violate resulting in fewer errors.
Microservices apps consume more memory; involve higher development costs initially; come with complex requirements regarding the operation, testing, deployment, and management; and need a greater level of developmental proficiency and expertise.

Microservices vs Monolithic Architecture: Comparison

Here are some major differences between Microservices and Monolithic architecture based on these crucial parameters.
In Monolithic architecture, the app’s UI, database, business logic, front-end, and back-end are integrated into a single codebase; whereas in microservices architecture, all the aforesaid app elements are subdivided and operated independently of each other. Likewise, the processes of testing and deployment are executed under one line in monolithic apps, while in microservices apps, these processes are scattered across different adapters and databases.
Monolithic architecture is deployed in a traditional format and caters to standard web servers. For deploying microservices, on the other hand, a plethora of approaches are supported – One service-One host approach (each service is deployed to one virtual host machine); One Service-One Container approach (microservices are isolated by docker containers, but resources like frameworks, libraries, and operating servers are shared); and Serverless deployment (third-party cloud services host and manage the servers on which the program runs).
Developing a monolithic application is easy if the app is new, but as the app gets bigger developmental challenges crop up. This is because the huge indivisible database needs the joint effort of the development team.
Microservices, on the other hand, offer loose coupling and several options to choose from while picking the tech stack; but the app developers must possess a more profiled knowledge. However, this structure allows developers to work independently on each component.
Testing is pretty simple in a monolithic app as a single script is used for testing the whole system while testing a microservices application becomes complex as every part of the app needs to be tested separately.
Microservices architecture enables continual development and deployment as every service gets individually implemented. With monolithic architecture, deployment becomes slower.
App Updation
The process of updating a microservices application happens uninterruptedly and doesn’t slow down the entire system. Contrarily, updating a monolithic app is voluminous and burdensome and for every update, the entire app has to be redeployed.
The bigger the monolithic app the more challenging it becomes to scale the app – for handling new changes the entire system has to be redeployed. In microservices apps, each part is scaled independently without downtime and so, involves fewer hassles while carrying out modifications.
Security and Reliability
Monolithic architecture involves a single source code; communication happens within a single unit, resulting in secure data processing and a simple monitoring procedure. Microservices architecture, contrarily, involves inter processing between multiple API connections increasing security threats, and hence, greater security monitoring is needed. However, in monolithic apps, one bug can hamper the whole system, while in microservices apps, one bug affects only that specific service and the bug can be topically fixed. Therefore, even when one service fails other services are not affected.

When should you pick Monolithic Approach?

You intend to develop a Simple App with faster Time-to-market
Monolithic architecture is an ideal choice for building a simple app that doesn’t require reinventing the wheel and the app is unlikely to scale rapidly. Moreover, developing the prototype of a simple app will take place at a fast pace leading to quicker time-to-market.
Smaller-sized Team and No prior Experience with Microservices
Start-ups with smaller-sized teams will benefit from the monolithic approach as experience and expertise in one tech stack will suffice and your team will not have to handle any developmental complexities. Furthermore, if your team doesn’t have any prior experience of working with microservices, picking this approach will be a risky business. In such a scenario, it’s better to start with a monolithic approach and migrate to microservices later on as and when needed.
Your app idea is Novel, Unproven, or the Proof of a Concept
If you have a novel app idea or planning to create a product that is unproven, your application is likely to evolve with time. Here, a monolithic approach will help in iterating the product speedily. Similarly, if your intended app is all set to prove a particular concept, you need to learn more within a short time and monolithic architecture will prove beneficial.

When should you pick Microservices Approach?

Your app is Complex and needs unprecedented Scaling
If you wish to develop a complicated software solution that involves a rich feature set, a substantial amount of personalization, extensive use of interactivity, a huge amount of business logic, or needs to be run by various modules; microservices architecture is your ideal pick. Start-ups who plan to build a highly innovative and revolutionary app that targets a humongous audience base and comes with heavy scaling requirements are recommended to adopt the microservices approach.
Need for Isolated Service Delivery
Microservices work better if you need to deliver independent services speedily. However, for this, you need a sufficient amount of resources as well.
A part of your Platform needs High Efficiency
For instance, your business is intensively processing petabytes of log volume. In such a scenario, you’ll have to create a service with a super-efficient programming language like C++ whereas the users’ dashboard can be created in Ruby on Rails.
Effortless Team Extension
If you commence your start-up with microservices architecture, your team will get accustomed to the idea of developing small services right from the very beginning and the teams will be segregated by service boundaries. So, later on, you can effortlessly scale up your team as per the need.

When is it advisable to migrate to Microservices Architecture?

It’s time to migrate to microservices architecture when your monolithic app grows big enough to create maintainability issues, when your business functions and their boundaries are crystal clear enough to be converted into individual services, and when your app needs scaling to deal with a humongous user load.
Example: The popular app Netflix started as a monolithic application. With time, the app experienced a surge in the demand leading to issues concerning performance and reliability. As such, the owners migrated their app to the cloud-based microservices architecture. Consequently, the app got segregated into hundreds of microservices and this approach enabled boundless expansion and scaling.

Summing Up:

Monolithic architecture as well as microservices architecture comes with its own set of strengths and challenges. So, when deciding on the most suitable pick for your start-up, you need to first define the requirements of your software development project. If you plan to develop a lightweight app and have budgetary constraints, it’s advisable to go with the monolithic approach. But, if your project is huge with complex requirements or you need to work with futuristic models like Big data, and you can spend on hiring several cross-functional teams, microservices is the most viable option.

Why Think of CNC Software as Digital Tooling?

Why Think of CNC Software as Digital Tooling?

If you have ever used a CNC machining tool, you would know how important the associated tools are for the CNC machine to work. The vises, grips, cutters, holders, tool heads, drawbars, and more complete the CNC machine, and they form the physical tooling part of the whole machine.
However, there is one more aspect of the machine which is just as important – the “digital tooling” of a CNC system. The CNC software is required to make the hardware of a CNC system work, and you think of it as digital tooling for the machine.
Here’s what this digital tooling does and why it makes for the central part of the CNC machine:
The CNC software that feeds the G-code into your machine is your digital tooling. If it weren’t for this software, you won’t be able to run the programs according to your designs.
There is no one software included in your digital tooling packet. It includes various software and systems required to complete the whole process of manufacturing a certain part. The CAD/CAM software has also advanced to be able to add G-code to CNC machines.
Let’s take a look at the CNC software and learn how they work and fit into the digital tooling box.

CAD/CAM Software as Your Digital Tooling

Whether you have a CNC lathe, mill, router, or some other machine, there is a typical workflow process followed by the CAD/CAM software to complete the task.
CAD software makes the 2D drawings and solid models that serve as the starting point from where the CAM software picks up and produces the G-code to run the CNC machine accordingly. Other than CAM, there might also be a Slicer software that feeds the G-code to the CNC system or a 3D printer.
Mechanical CAD programs are mostly used in CNCs rather than architectural CAD software. Some most popular CAD names for the CNC machine include AutoCAD, Inventor, Solidworks, Rhino3D, and more.

Other Software in CNC Digital Tooling

Slicer software is similar in function to CAM software but is a bit more complicated and used for 3D printers.
There are other CNC programming apps associated with work related to G-code such as G-code simulators, G-code editors, G-code verification software, and more. Another inclusion in the digital tooling kit is the CNC control software which takes the G-code and provides the right electrical outputs, so the CNC could move in the correct order to manufacture according to requirements. It could be separate software or come in a combination of software and hardware.
Then there are CNC Utilities which are used for calculating feeds, speeds, and many more functions. There are several shop floor and manufacturing software as well which help in taking inventory, predicting job costs, managing operations, and more functions associated with the manufacturing process via a CNC machine.

What should you look for in CNC software?

So, how do you choose which software to buy for your digital toolkit from among the many options available today? This is especially complicated with different software performing different functions. You may not know which software function a certain CNC machine needs for optimum performance. Read on to find out what attributes you should look for in CNC software for your CNC machine.
Free and Paid
Take a quick look at CNC software for machines, and you will be bombarded with hundreds of results. There will be AutoCAD, AutoDesk, and other latest software. Some will work online through cloud computing, while others will need to be downloaded onto the computer.
However, the critical distinguishing factor between most of these options will be the price of the digital tool. The pricing could vary. There are free ones as well as paid ones with a one-time fee. You might be tempted to jump on the first free option you land upon. But here’s what you need to remember before taking the plunge with either free or paid software.
Your machining tools and the outcome will only be as good as the codes running the machines. The G-codes will be as good as the programs or software they are created on, no matter whether you are using a CNC lathe or a mill. This doesn’t imply that all free tools are bad. But your focus must not be on the price rather the quality of work they can provide you. The fact is, a free program with a buggy code can ruin your products and lead to more costs incurred than saved during the purchase.
Paying a small fee at the beginning might be worth all the effort, time, and money you will save later in the manufacturing process.
2D and 3D
Your choice of software will be strongly influenced by the kind of machine you are using and the resultant need. If you are designing in 3D, the CAD programs that work best with it will be different than if you are working with 2D designs.
There are some CNC software that support working on 3-axis, while others work better with 5-axis machines or multiple axes. You would want to consider that as well.
Feeds and Speeds
Advanced feeds and speeds software help with calculations for the final G-code that gets fed into the CNC machines. Other than a CAM program for dealing with the G-code, it could be good for precise measurements to install a feeds and speeds program.
Separate or Combined
CAD and CAM can be separate programs and can be all-in-one programs as well. Look into which one suits your needs the best. A centralized option may not always work the best. You need to audit your skills and output required and then make the decision.


Digital tooling is just as significant, if not more, as hardware tools. Softwares and programs need to be in top shape as well if you want the output to be precise and accurate. Most people won’t pay much attention to choosing software.
Don’t leave it to pricing only. Choose your digital tools with caution. They are going to run your hardware.
