Cloud Case Study

About Customer:

This customer is one of the largest Government universities in Kerala, who required Cloud migration services.

The Challenge:

Till 2018, this university used physical servers, storage, and networking equipment hosted in own datacenters and co-located datacenters to support students in 300 + affiliated colleges. However, as the number of students and the prospective students increased, servers started to overload and critical applications and services like e-Payment for fees, Common Admission Program (CAP) and the subdomains of various departments could not be accessed during peak times. These availability issues persisted during every admission season and during the period of fees collection/payment. The unavailability of compute resources and subsequently the applications during crucial times were unacceptable to the university.

Why Amvion?

The university determined that a public cloud service could deliver the availability needed, as well as the scalability to support growth and the elasticity to manage demand peaks. The university reviewed Amazon Web Services (AWS) through Amvion and undertook a detailed assessment for about 4 – 6 months by running the said applications in a production environment although in a test/assessment mode.

This university is now running Amazon Elastic Compute Cloud (Amazon EC2) instances to provide the compute resources to run its applications and services, with Amazon Elastic Block Store (Amazon EBS) and Amazon Simple Storage Service (Amazon S3) providing storage resources. While Amazon Cloud Watch provides monitoring and alerts for AWS resources and university’s applications and website. The university also uses Amazon Relational Database Service (Amazon RDS) for the following advantages over database on a traditional environment.

  • Lower administrative burden with AWS Management Console, the Amazon RDS Command Line Interface or simple API calls to access the capabilities of a production-ready relational database in minutes.
  • Performance with general purpose and provisioned IOPS (SSD) storage.
  • Scalability with Push-button compute, easy storage and read replica scaling.
  • Availability and durability with Automated backups, Database snapshots, Multi-AZ deployments and Automatic host replacement.
  • Security with Encryption at rest and in transit and Network isolation.
  • Manageability with Monitoring and metrics, Event notifications and Configuration governance.

The Benefits

The university has achieved a range of benefits from using AWS. The university has achieved 99.9999% availability for its website, applications and services. There is a considerable amount of savings in personnel and datacenter facilities costs with AWS in comparison to the on-premises and co-located datacenters. The admission season in the year 2018-19 had hits of 4500 – 5000 hits/second during peak hours which was handled seamlessly on AWS cloud with zero second downtime. The university was also able to understand the exact compute resources being used at normal and peak hours and were able to downsize the resources from that being used in on-premises and colocated datacenters and optimize the resources to that needed exactly on the cloud thereby reducing the operational cost.
