Scalable cloud for urgent massive email delivery

When there is the necessity to send an email message to a big list of email destinations and following the valid standard Simple Mail Transfer Protocol (SMTP), it takes too much time to be delivered, because this message is sent one by one to each of the email destinations. If we talk also of an important message that all the recipients are in need to receive it in a timeless way, converting this need as a Real Time System, that will let them being able to take the corresponding immediate actions and specifically we can say that all the destinations of this email are really looking forward of this message, with this we can say that it will never be taken as a SPAM email. With all the mentioned above, in this paper we propose a solution by provisioning resources, and escalating the exact infrastructure needed for the time that is going to be used to deliver the message within a small time requirement defined by a Service Level Agreement (SLA). In this manuscript, we designed the procedure to determine the structure, not only the VMs needed to achieve the requested time, and taking into account the contention problem and we also made a cost/efficiency comparison with the different parameters available for the customer.
