Abstract
Green SLA (GSLA) is a formal agreement between service providers/vendors and users/customers incorporating all the traditional/basic commitments (Basic SLAs) as well as incorporating Ecological, Economical, and Ethical (3Es) aspects of sustainability. Recently, most of the IT (Information Technology) and ICT (Information and Communication Technology) industries are practicing sustainability under green computing domain through designing green services at their scope. However, most of these services only focused on power consumption, energy efficiency, and carbon emission. Moreover, the sustainability can not achieve without considering 3Es simultaneously. The recent development of sustainable GSLA are assisting to identify the missing green services under 3Es. This research attempts to design all missing green services for sustainability by using global informational model of Green SLA. All these newly identified green IT services could reside with other existing services in the industry. Additionally, the design and evaluation technique of these new green services could be used as a guideline for the ICT engineers and as well as other industries too. Moreover, the evaluation and monitoring of new green services are justified using general questionnaires design and analytical tools among the 20 startup ICT industries in Bangladesh and Japan. The proposed idea of designing new green services and their justification methods would be helpful for the ICT engineer to practice sustainability in their competitive businesses.
