Introduction
SaaAS
Mobile Agent based Service for Cloud Computing in Internet
Cloud Computing
paradigm for sharing data and computations over a network.
Mobile Agent
Characteristics In Internet:
Autonomy, Personality, Communication, Mobility, High
Performance and Fault-tolerance .
Codes Load
loading code from one domain to another domain.
Convergent Coherence
can reduce the communication in WAN.

Abstract
Current cloud computing systems perform
only in LAN.
SaaAS implements cloud computing for
Internet environment.
Parts:
1. introducing mobile agent into cloud computing
2. presenting a high performance code and data
3. presenting a novel data coherence mechanism

Existing System
To implement service migration:
uses RPC and RMI can achieve good
performance in LAN.
• Disadvantage:
not suitable for Internet or WAN.

Proposed System
Mobile Agents are used for service
migration.
By using the mobile agent rather than
RPC/RMI , SaaAS is more suitable to
work in Internet.

Modules of the System:
◦ 4 modules in the system
1. Admin: To maintain the data in Clouds
and to provide them to users.
2. User: A user can utilize the services.
3. Domain Code Server: To check the
data locks and provide the data to user.
4. Main Code Server: Maintains the
locks of data stored in clouds

Testing cases
1. Unit Testing
2. Integration Testing
3. Integration testing for Database
Synchronization

1 . UnitTesting:
 All field entries must work properly.
 Pages must be activated from the identified link.
 The entry screen, messages and responses must not
be delayed.

2 . IntegrationTesting
 Check that components or software applications.
 Testing of two or more integrated software
components on a single platform

3 . Integration testing for Database
Synchronization:
 Testing the Username & password, Migration and
Synchronization screens.
 user does not have enough privileges to invoke a
screen, the link should be disabled.
 Any modification in the Master server should be
reflected in the Slave server.

CONCLUSION
The cloud computing system can not only
work in Intranet but also work in
Internet.
SaaAS is more suitable to the cloud
computing system which works in
Internet.
SaaAS to have good flexibility, adaptability
and usability and to be more suitable to
work in Internet than conventional cloud
computing system
