Benefits Of NGN Based Clouds
Cloud’s integration with NGN (Next Generation Network) is perhaps one of the most actively pursued areas within Cloud R&D given the promise of efficiency. NGN will inject interoperability in already established network infrastructures where every communication will be done in one format using a common protocol. Packet based communication is proposed in NGN standard along with circuit switched PSTN networks. Currently, interoperability is a pain within Cloud computing where different VMs (Virtual Machines) can’t interact in cross platform environments. This also presents a challenge for hybrid Cloud deployments.
NGN integration with Cloud will also significantly reduce the need for expensive switches, routers and memory devices since that could easily be replaced with commercial off-the-shelf (COTS) hardware. COTS hardware will allow more easy, efficient and optimized load balancing because the XED mobile technology, which allows mobile and data communication to take place on different layers of the networked physical architecture. The cloud service offered by Amazon in the form of EC2 is the best example of this integration. NGN will also enable the third party integration with the cloud based IaaS applications for SLA compatibility.
DSS (Decision Support Systems) based on Clouds are very open for extension with NGN since it’s integration provides optimal access to remote resources in a secure and interoperable manner. There are no issues of security and data redundancy because of the service oriented architecture of NGN based Clouds which allow deep penetration testing of data integrity issues. GOS middle and CNGid is the most useful technology being used for the integration as most of the clouds using NGN integration are implemented in Job Submission Description Language (JSDL). JSDL gives an option to implement different middle wares for the cross platform interaction ease.
NGN based clouds also allow temporary, adequate resumption of services in case SLA based applications are not working. This will enhance the quality of service of the overall communication with the end users since the service provider will gain time for enabling error handling mechanisms which run in the back-end. Service discovery techniques like API calls to the UDDI with the encrypted language support can also be easily used for problem solving. Security issues in Cloud that are perhaps one of the intensely discussed topics of today’s Cloud computing domains and this can be adjusted with different techniques like User Equipment (UE) authentication and authorization.
