Substantial development of Information and Communication Technologies (ICTs) has imprinted a great role in our lives and lifestyles. The ICTs provide a convenient environment for the customer for computing, communication and collaboration. The Cloud Service Providers (CSPs) offer several types of IT resources/services via the internet. These are provided based on a Service Level Agreement (SLA) signed by both the parties, i.e., CSPs and customers/ clients. As a matter of fact, several trust violations and lack of transparency have been observed in terms of metering of consumed cloud services along with nonfunctional requirements promised (i.e., quality, availability/uptime and greenness) in products/services provided by CSPs over the cloud. In order to establish satisfactory trust and transparency in billing and metering of services, a trusted environment is needed. As a primary investigation, several discrepancies are observed in billing, because SLAs are designed and used by CSPs side only for measurement and billing along with the Quality assurance of Services (QoS). It implies that CSPs have no transparency and monopoly on the measurement and billing systems. This study is an effort to empower the cloud clients/customers through introducing a new clientside metering and billing system model for consumed cloud services. This system can help the customer to cross-verify the measured/metered and billed services with promised quality attributes like greenness. It can assure better transparency and trusted billing. This paper considers the performance, service outage, performance satisfaction, update, violation, and greenness, etc. Finally, a simulated model for Client-Side Metering and Monitoring of SLA, termed as DPS-Yemane-Shareme Client-Side Measuring and Monitoring (CSMM) model, is developed and validated using E-Draw Max, AppNeta and 42U.
The use of Internet and Information and Communication Technologies (ICTs) is considered to deliver cloud computing resources in the 21st century. The resources available on cloud computing can be accessed by anyone from anywhere over digital devices without any digital divide. In order to access and use the services efficiently, an agreement between the customers and Cloud Service Providers (CSPs) is needed. The Service Level Agreement (SLA) is assumed to facilitate a transparent and trusted environment.
