# Cloud-Computing-Concepts-Part-1 : 

*	https://www.coursera.org/specializations/cloud-computing

# What is the project? 

*	The project is about implementing a **Gossip Protocol**.

*	The main functionalities of the project :

	* **Introduction** : 

	Each new peer contacts a well-known peer (the introducer) to join the group. 

	* **Membership** : 

	A membership protocol satisfies completeness all the time (for joins and failures), and accuracy when there are no message delays or losses (high accuracy when there are losses or delays). 

# Detail & Principle :

*	Data Structure of Message : 

```cpp

typedef struct MessageHdr {

	enum MsgTypes msgType; 

	vector< MemberListEntry> member_vector; // membership list of source

	Address* addr; // the source of this message

}MessageHdr;

```

*	Principle of **Gossip Protocol** :

# How do I run the Grader on my computer ?

*	There is a grader script GraderNew.sh. It tests your implementation of membership protocol in 3 scenarios.

	* Single node failure

	* Multiple node failure

	* Single node failure under a lossy network.

```

	$ chmod +x GraderNew.sh

	$ ./GraderNew.sh

```

# Result

*	Points achieved: 90 out of 90 [100%]
