RGPV: Distributed System: Unit 1

GOALS OF DISTRIBUTED SYSTEM

The four important goals that should be met for an efficient distributed system are as follows:

1. Connecting Users and Resources:-

• The main goal of a distributed system is to make it easy for users to access remote resources and to share them with others in a controlled way.

• It is cheaper to a printer be shared by several users than buying and maintaining printers for each user.

• Collaborating and exchanging information can be made easier by connecting users and resource.

2. Transparency:-

• It is important for a distributed system to hide the location of its process and resource. A distributed system that can portray itself as a single system is said to be transparent.

• The various transparencies need to be considered are access, location, migration, relocation, replication, concurrency, failure and persistence.

• Aiming for distributed transparency should be considered along with performance issues.

3. Openness:-

• Openness is an important goal of distributed system in which it offers services according to standard rules that describe the syntax and semantics of those services.

• Open distributed system must be flexible making it easy to configure and add new components without affecting existing components.

• An open distributed system must also be extensible.

 

4. Scalable:-

Scalability is one of the most important goals which are measured along three different dimensions.

• First, a system can be scalable with respect to its size which can add more user and resources to a system.

• Second, users and resources can be geographically apart.

• Third, it is possible to manage even if many administrative organizations are spanned.
