Estimation of software maintenance effort improves the overall performance and efficiency of software. The Constructive Cost Model (COCOMO) and other effort estimation models are mentioned in literature but are inappropriate for Python programming language. This research aimed to modify the Constructive Cost Model (COCOMO II) by considering a range of Python maintenance effort influencing factors to get estimations and incorporated size and complexity metrics to estimate maintenance effort. A within-subjects experimental design was adopted and an experiment questionnaire was administered to forty subjects aiming to rate the maintainability of twenty Python programs. Data collected from the experiment questionnaire was analyzed using descriptive statistics. Metric values were collected using a developed metric tool. The subject ratings on software maintainability were correlated with the developed model's maintenance effort, a strong correlation of 0.610 was reported meaning that the model is valid.

It is widely used in many organizations nowadays and becoming more popular because it changes the way in which Information Technology (IT) of an organization is organized and managed. It provides lots of benefits such as simplicity and lower costs, almost unlimited storage, least maintenance, easy utilization, backup and recovery, continuous availability, quality of service, automated software integration, scalability, flexibility, and reliability, easy access to information, elasticity, quick deployment and lower barrier to entry. Due to increasing use of cloud computing service in this new era, the security issues of cloud computing have become a challenge. Cloud computing must be safe and secure enough to ensure the privacy of the users and the cloud providers. In this paper current emerging and researchable privacy concerns affecting cloud pr...
