Abstract:
The present demand for cloud computing is driven by its scalability and adaptability, making it widely employed in enterprises. A Service Level Agreement (SLA) is a contractual arrangement between cloud providers and clients that ensures the stated level of services will be available. In order to evaluate the compliance of the services to the SLA, it is critical to monitor the availability of the cloud services. Cloud service companies offer several monitoring tools. However, such assessments are often influenced by bias, which prompts demands for impartial assessment of service level agreements (SLAs). The objective of this study is to address the issue of monitoring service availability characteristics, specifically uptime and downtime, in relation to SLA. To achieve this, a monitoring tool called SLA Analyser is proposed. The solution comprises a cen-tralised application that generates and collects data in the primary registry database, along with a compliance report generator tha
t computes cloud service availability using previously gathered data and compares it to the SLA availability parameter. An illustrative report is generated based on the gathered and processed data. This study specifically addresses the reliable assessment of SLA for both clients and service providers. Moreover, this study analyses the challenges associated with SLA monitoring and the repercussions of neglecting its assessment. This approach is particularly essential to organisations that use many cloud services from various vendors. The SLA Analyser was employed to monitor the availability of the cloud database services. In order to mitigate financial losses and uphold a positive reputation for consumer confidence, it is essential to validate the SLA.
