RPC vs Web Service: Difference and Comparison

Remote procedure call (RPC) is a type of inter-process communication technology. This speeds up a procedure or makes a subroutine of a computer programme run in a new address space.

Which is frequently referred to as a different computer with a shared network. Where the programmer codes all the specifics based on remote interaction.

Web services are a type of web API or application programming interface. These APIs are accessed and executed remotely via the HTTP or hypertext transfer protocol.

Key Takeaways

  1. RPC is a protocol that allows programs to request services from other programs on the same computer or network.
  2. Web Service is a protocol that allows programs to request services from other programs over the internet.
  3. The main difference between RPC and Web Service is the location of the programs being accessed and the network they operate on.

RPC vs Web Service

RPC is used to describe a method of communication that allows one application to call functions or services of another application on a remote system. Web services are a set of protocols and standards for exchanging data between applications over the internet using protocols such as HTTP, XML, etc.

RPC vs Web Service

A remote procedure call, or RPC, is recommended in this scenario and is used with a heavy server and client approach. The server or the client either fulfils a program’s request.

The client receives the performance request while the server handles the execution. RPC has a server environment that is extremely busy and difficult.

It is extremely difficult and difficult to assemble a large number of clients to work in this situation. Web Services communicate asynchronously.

In the case of larger facilities, this entails a variety of routing strategies and network spraying. When the Java connection can’t be seen or the application can’t execute on Java.

The use of Web Service comes into play. In other words, Web Service technology does not require extra coding on the client or server.

What is RPC?

A remote procedure call, or RPC, is an inter-process communication technology. This speeds up a procedure or causes a computer program’s subroutine to be executed.

In a new space of address, which is referred to as a different machine connected to a shared network. Where the programmer codes all the specifics based on remote interaction.

A remote procedure call, or RPC, is advised in this circumstance and is used with the support of a hefty server and client paradigm. A program’s request is either fulfilled on the server or the client side.

On the other hand, the performance request is sent from the client and executed from the server. RPC has a server environment that is extremely busy and difficult to navigate.

Getting several clientele to work with is extremely difficult and difficult in this situation. In the case of RPC, the functions can be called with the help of any multi-application.

RPC is heavily skewed toward systems that work in a similar way to Java-based applications, such as EJB, which is also a communication platform.

The activities of the Remote procedure call, known as RCP, are simultaneous.

What is Web Service?

Web services are a subset of web APIs, also known as application programming interfaces (APIs). These APIs are accessed and executed remotely via the HTTP (hypertext transfer protocol).

When there is a need for any application that cannot run on Java and is thus connected to a web service, a web service is recommended.

In the case of Web Services, working with many customers on multiple services is fairly typical. However, to use the web service, it must be accessed via HTTP.

In the case of larger sites, this entails a variety of routing approaches as well as network spraying. When the Java connection can’t be seen or the application can’t execute on Java.

The use of Web Service comes into play. In other words, Web Service technology does not require any form of specific coding on either the client or the server to function.

Web Services use asynchronous communication to carry out their tasks. Web Services, on the other hand, are mostly used to synchronise data.

The Web Service’s functions can be called from any application that uses the HTTP protocol but in XML format.

Main Differences Between RPC and Web Service

  1. RPC, or the abbreviated form of Remote procedure call, is Inter-process-based communication technology.
  2. This boosts up a procedure or causes a subroutine of a computer program for execution in a different space of address, which is commonly referred to as a different computer with a shared network where the programmer codes all the details based on remote interaction.
  3. On the other hand, web services belong to the group of web APIs or simply APIs, application programming interfaces. These APIs are accessed and executed via the HTTP or hypertext transfer protocol, which is done remotely on a system.
  4. The use of a Remote procedure call or RPC is employed with the help of a heavy server and client model and is recommended in this scenario.
  5. The request for a program is either performed on the server or client end. However, the performance request is sent on the client side, and the execution is done on the server side.
  6. On the other hand, the use of web service is recommended when there emerges the use of any application that does not possess the potential to be operated on Java and, thus, is connected to the web service.
  7. RPC possesses a server environment that is highly congested and challenging in nature. It is challenging and tough to gather multiple clients to work with here.
  8. However, on the contrary, working with multiple clients on multiple services is very common in Web Services. However, for the web service to be invoked, it needs to be over the HTTP. This involves various routing techniques and network spraying in the case of bigger sites.
  9. RPC is fully biased to platforms that work similarly to running applications like Java, that is, EJB, which is also a communication platform.
  10. On the other hand, Web Service comes into play when in any application, Java’s connection can not be witnessed or does not possess the potential to run on Java.
  11. In other words, Web Service technology does not possess the potential to function with the help of any special coding with the client or server.
  12. The actions of the Remote procedure call or RCP can be considered synchronous. On the other hand, the actions of Web Services are asynchronous communication.
  13. However, the main use of Web Services is to synchronize them.
  14. The functions in the case of RPC possess the potential to be invoked with the help of any multi applications.
  15. On the other hand, the Web Service’s functions can be invoked with the help of any application that uses the HTTP protocol but in XML format.
