Excelsoft has had success with AWS. According to Subbakrishna MV, the company has measurably increased its bottom line since switching to AWS and has experienced other benefits including the folliwng:

• Cost Savings: As a result of the AWS technology, Excelsoft has drastically reduced its operating costs. With AWS, the cost to deliver one online assessment is about 10 times lower than the cost associated with using the physical hardware (co-located servers).
• Development Hours Saved: Because deployment is efficiently managed with AMI creation and bundling, AWS has enabled Excelsoft to reduce the total developer time required for deployment and associated tasks to about 20 percent of its team's focus. This is a marked reduction from the 70 percent required to perform the same tasks on the physical hardware.
• Reduced Time to Market: Amazon's solutions allow the company to deploy its products to customers very quickly. Now, it takes only a day or two to provide product service to a new customer, where deployment previously took at least a month using physical hardware.
• Site Traffic Management: Excelsoft estimates that the cloud infrastructure receives approximately 200,000 visitors per month using applications on AWS. The applications include taking tests and assessments, uploading content, browsing courses, etc. Despite the number of visitors, computing capacity is handled well.

Mr. Subhash M, Head e-Learning at TIME, one of Excel-Soft's customers, adds, "We are one of the biggest management entrance training institutes in India conducting about a million tests every year. After evaluating several online assessment engines, we zeroed in on Excelsofts's SARAS due to configurability of the application and reputation of the organization. Initially we installed the application on a dedicated server. We faced problems due to huge variability in our load -- the number of test takers on weekends is almost 10 times that on week days.

"Having dedicated servers to meet the peak load was becoming expensive. On the recommendation of Excelsoft, we moved to the AWS Cloud. This provided us the flexibility to scale up/down the hardware infrastructure depending on the expected load. This took care of the variability in load without having to spend on dedicated servers for peak load.

"Excelsoft also took the responsibility to manage the cloud infrastructure for us. They have done a very good job of managing the cloud infrastructure for us and helped us in achieving good service levels.

"We have conducted more than 300,000 tests on SARAS using Amazon's cloud computing facilities in the last five months. All in all, we are very happy with the AWS Cloud as well as Excelsoft's services in managing cloud computing for us."

Subbakrishna MV summarizes Excelsoft's experience: “Our customers’ business expects a high level of scalability and availability. This was a continuous challenge to fulfill for us when using physical servers. AWS enabled us to achieve higher levels of scalability and availability. Our relationship with AWS is a win-win situation for Excelsoft, its customers, and AWS.”
