What is the difference on Web API, Web Service, Microservice

We are experts in APIintegration and web services  — two things that can work together but do not serve the same purpose. Furthermore, microservices function differently than the other two so we have here tried to explain the difference.

Giving you an understanding the differences between web APIs vs. web services vs. microservices. Explain how best to use them each of them.

Web API explained

API stands for Application Programming Interface. This interface allows people to further build upon another application’s functionality and data. One might understand them as building blocks you can use to make almost anything as they can be found in everything from Spotify to Yahoo Finance.

The API frameworks allow developers to perform tasks that aren’t all that different from everyday events. For instance, think of giving an order to a server, that server putting your order in, and then bringing back the order when it’s ready. This step-by-step process returns the desired outcome: a tasty meal (in this case). A web-based example might be someone signing up to a new e-Commerce site by using their Facebook account.

Essentially, APIs help sites to communicate on the web and understand information (regardless of programming languages) in order to facilitate processes. HTTP protocol requests allow for sending data and receiving data. The only caveat is thatAPI’s demand constant testing to make sure consistent functionality.

Types of Web API

As of now, people use four distinct APIs.

  • Composite APIs. These merge service and data APIs. The series of tasks operate synchronously due to execution and NOT due to task requests. These APIs can expedite the execution process, as well as improve web interface listening performance.
  • Partner APIs. These require licenses or special rights for access as they are not generally available to public developers.
  • Open APIs. In contrast, Open or “Public” APIs bear no access restrictions and can be accessed by the public.
  • Internal APIs. As the name suggests, these operate as “Private” APIs within internal systems. They can be used among internal teams in a single company for service or product improvement.

Some APIs also require keys for authentication before allowing the mixture of information

Web Service Explained

A web service, in contrast to an API, functions more like a resource that’s available using the internet. The network-based resource can be applied to specific tasks, but they require a network to function. This means that all web services are APIs, but only some APIs are web services.

A web service works by supporting interoperable machine-to-machine communication using a network. As such, web services tend to be connected with SOA or Service Oriented Architecture. This allows for different features to be separated then made available as various services within a network.

What Is Web Services Testing?

This testing helps to validate web services in various ways. Functional testing is a main facet along with gauging overall performance, reliability, and security of APIs. Many might consider web services testing similar to unit test in some ways since it can isolate the function tested to a scope limited to requests and responses associated with a specific protocol.

Types of Web Services

Industry veterans might recall when Windows Communication Foundation (WCF) replaced Microsoft web service technology from earlier. But the average web service framework can function in many different environments  Some sample options :

 

  • .NET Framework
  • Apache Axis
  • WSO2 WSF/PHP
  • XML Interface for Network Services

Web API vs. Web Service

Now that we know what item each is, we now need to understand the difference between Web APIs and Web Services. One of the most obvious differences is that web services, unlike APIs, require a network to function. APIs can function online or offline.

Furthermore, web services are not protocol-agnostic like APIs. APIs can use any design style or protocol, but web services are restricted mostly to SOAP or Simple Object Access Protocol.

Public APIs are often also open source and more transparent about their documentation. Web services sacrifice that transparency for more specific data, partners, and security. However, API security remains a challenge.

What Is a REST API or Other Web Service APIs?

REST stands for REpresentational State Transfer and, as an architectural option, it allows for standards among web-based computer systems. These RESTful systems facilitate communication between systems more easily, thus separating server and client concerns.

Other web service APIs include JSON-RPC, XML-RPC, and SOAP.

Difference Between SOAP vs. REST

SOAP makes use of only XML as its data transference format. This means that REST can use SOAP, but SOAP is unable to use REST. But the differences don’t stop there in the REST vs. SOAP list.

Both offer different functionalities for various use cases regarding APIs and web services.

Microservice Explained

Microservices are architectural styles typically used in modern web apps that require more fragmented functionality. That means that each service is a modular, unique process that can be deployed independently. The lightweight architecture still makes use of SOA and can be especially advantageous for larger companies.

Separate teams can work on various items without encountering difficulties. But this necessitates communication among the different parts which is where APIs come in. However, web services and microservices are not quite the same either.

Web Service vs. Microservice: What’s the Difference?

It’s best to consider a microservice as an autonomous application designed for a single, specific service as part of a larger application architecture. In contrast, a web service acts as a strategy to facilitate service availability across applications by using a web interface.

API, Web service or micro service - selecting!

Microservices, APIs, and web services can all be used separately or togehter in your services. The choice between them is likely to depend on the specific protocols, messaging formats, or communication styles you need to support – or simply in what your software offer or what external providers do use.
