Below shows a non-redundant 3-tier architecture template usually employed primary for basic test of the interactivity between each architecture tier and for development purposes to save on resources and costs.

The figure below shows a redundant 3-tier architecture template which is essential for fail over and recovery purposes using a Server Array based application tier to take advantage of auto scaling in the cloud.

According to report of the incident, computer hackers infiltrated the cloud-computing company of which the entertainment firm had entrusted data to. 100 million customer account files were compromised because the hackers had a legitimate account set up with the cloud computing site, the cloud breach in this situation was an exceptional scenario. Secondly, the was a cloud-security breach which involved a company that delivers e-mail services to other businesses and was in charge of over 40 billion e-mails annually for more than “2,000 global brands.” After the breach in 2011, the hacked company specified that “clients’ customer data were made public by an unauthorized entry into the company’s email system. When the breach was discovered, a lot of customers of the e-mail services company sent warnings to their own customers informing them to the existence of the stolen information.
