In an effort to be as simplistic as possible, software design architecture can be described as such:
- Microservices: The application is autonomous and small, meant to handle a designated service for a much larger architecture, usually for business capabilities. Go herefor microservices design ideals.
- Web Services: These are specific strategies meant to avail the services of a single application to another through a web-based interface.
Both of these are useful in developing application architecture. A microservices structure is almost like a community of independent software modules loosely connected with an intention to serve. You can integrate more apps/microservices with the current ones that offer APIs in order for you to do so.
Web services are comparable in every aspect, service-oriented and also a modular structure, but these connect through web services. Developers have the opportunity to connect monolithic apps, microservices, and other options using web services to form an extensive app.
Comparing Web Services and Microservices
While there are distinct differences between the two software developments, there are also comparable. It is not uncommon for architectures to include a mix of web and APIs for integration of the microservices “tasks” and the applications comprising the architectures. Let us tackle the question “microservices vs. web services: what is the difference?” and read further below to know the answer.
** Specificity of Services
You will find with a microservice development, distinctly specific service or duty occurs. Constantly, within a single application, web services have the capacity to perform many services. With this option, you can manage and control access to different services belonging to a single app.
In either situation, a developer has the ease of adding to the structures as well as upgrading or even removing microservices and apps that are a part of a bigger component. The modularity of this nature creates a sense of flexibility and agility since upgrades are much more cost-effective, are simple to carry out and give a rapid result without significant disruption.
With API connectivity, there is great flexibility since HTTP and HTTPS are supported, and message formats/protocols of a dissimilar nature can achieve connection. HTTPS is not supported by web services with the message protocol/format being shared with the connected components. That can be overcome with the right tools.
Many containers can run together on an operating system, and these are how microservices function. In this way, there is less overhead due to minimal operating system licensure necessary for varied services comprising an extensive structure.

APIs also offer universal connectivity saving time and costs in attempting to establish an API connection. There is no need for intensive labor to develop a “point-to-point, hand-coded” option.
Being an HTTP-based display of APIs means web services can avoid the time-intensive labor and expenses. Each is also pluggable, meaning upgrades will be fast, budget-friendly, and straightforward.
Why Use Web Services and Not Simply Implement Microservices?
API and microservices generate the most attention in the modern age, but there are some situations where the web architecture is ideal for connecting apps. In some instances, there is a possibility you might implement a blend of monolithic and micro applications with which a mix of the web and APIs are responsible for the connectivity of such a diverse scheme.
With a microarchitecture, each “container” has a database connection of its own which can prove draining on resources when all of them are “reaching out” to the databases simultaneously. Monolithic applications do not require the magnitude of calls or connections preserving resources.
The developer can still benefit from a service-oriented approach but decrease the likelihood of slowdowns caused by a run on databases.
We tried to make the language as simplistic as possible in describing the differences between the two architectures. Software development is complex, with a novice (plus business leaders) getting lost in the language. It is often necessary to reach out for assistance in the development process.
As far and micro and web design, each has its own pros and cons with comparable and distinct differences. There are instances where the two can work cohesively and times when the web makes more sense. You need to look at your particular needs and move forward from that point.
