Build Linux Remote Procedure Calls - from scratch in C

Course details

About This course is about Developing your own Remote procedure calls. The essence and real strength of this course is No use of any third party libraries. I follow this principle in all my other courses. Whatever you learn through my courses, you learn from absolute ground level. This course does not violate the principle and teaches you how to build Remote Procedure Calls step by step from absolute scratch - No framework, tools, supporting libraries or anything - just pureC.

This course actually lays the foundation of many future System Software Projects. Few of which are below and is a part of this course curriculum.

Remote Procedure Calls (RPC) is a technique to invoke the function/procedure which actually resides on different physical machine running somewhere else in the network - hence the name remote procedures. In this course, you will learn the concepts working behind the scenes. The same concepts can be extended to implement other system programming concepts, besides RPC, such as - Data Synchronization andCheck-pointing the application state. This course promise to deliver the complete content on developing RPCs in its initial release.

Data Synchronization - It is a process to synchronize the complete application Heap state to remote machine. The remote machine will build the mirror heap state. In the event, the first machine fails, the remote machine can take over as it has all the state required to resume the operation of failed machine.

Check pointing - It is a process of saving the application Memory state to disk/file persistently, so that, the application can be restarted/resumed any time building the exact same Memory state from Memory snapshot stored earlier to secondary storage.

Check pointing shall be delivered in subsequent releases of this course.

Who should do this course?

Beginners Please take this course at your discretion. You should be good with C pointers and how C objects are laid out in memory. I expect you to be at-least above beginner level in C programming. This means, that only very enthusiastic students who wants to get an edge over the smartest student in their college should enroll. Average students Pls excuse. Job seekers and professional developers Must enroll. The concepts you learn from this course is language agnostic and having learned them will enable you to implement the RPC/Data-Synch/Checkpointing in any programming language of your choice. If tomorrow you happen to work in Java, you shall be knowing how RPCs work at the lowest level of implementation.

Pre-requisite

C and being good at pointers is a pre-requiste of this course. A minimal socket programming back-ground is desirable but not mandatory. We designed this course starting from absolute basics and building the foundation of learners first before actually pulling the course at full throttle. If you are not good with pointers and memory manipulation in C, Pls enroll only after meeting the pre-requisite criteria.

Also, Please just do not sit and watch my codes. Write your own codes, even if it is same as mine !

Programming Language used In this course :

We have a strong reasons to choose C as a language for this course:

RPC is a technique which if knowing the concepts can be implemented in any programming language of your choice. Learning RPC using C helps you understand what is going on behind the scenes. C language really exposes the low level details about how system actually works. In System programming, C is the only language to be used and there is not even a remote substitute of this language when it comes to System programming.

No Third Party libraries

Whatever logic you implement, you need to implement it from scratch, beginning from #include<stdio.h>. This course do not suggest taking help of any third party library to get the jobs done. Use of external libraries completely defeats the purpose of the course. However, it is recommended to use third party libraries for commonly used data structures such as linked lists/Trees/Queues etc which saves a lot of time implementing these data structures.

RelatedCourses

RPC is one way of carrying out Inter Process Communication between two processes running on separate machines in the network. You may also want to check my another course in which Linux IPCtechniques has been discussed.
