How a multinational oil & gas company achieved cost savings with AWS

Migrating to a highly compliant cloud setup leveraging Wipro’s expertise in AWS led to cost savings of 47%

Client background

Industry: Energy

Products or Services: One of the six oil and gas “supermajors”

Areas of operations: Global

Challenges

The client’s business had complaints about IT costs, speed of delivery and quality of service, which were all deemed unacceptable. Also:

Data centers were running out of space, cooling ability and power. (It was taking 3.5 months to put a router in data center)
Number of servers was increasing dramatically (7-10% per year)
The existing service levels, where it was taking 42 days to provision server for storage, was unacceptable
There was no incentive to deliver something sooner than the agreed upon SLA

There was no transparency in the system– business did not understand what they were paying for. IT charges were not commensurate to business.

Solution

Wipro’s solution included the following:

Establishing a cloud Center of Excellence to enable enterprise-wide access to cloud
Designing, deploying and maintaining the AWS (Amazon Web Services) architecture in compliance with architecture and security standards
Planning a Cloud Business Chargeback capability to ensure cost transparency and usage of services
Establishing a Cloud Governance Framework to define roles and responsibilities of client, IT partner and AWS
Designing and deploying self-service portal with role-based access and real-time feedback on costs, warnings, etc.
Designing the AWS architecture for a virtual private cloud setup with robust and secure network connectivity with value adds like data encryption and windows authentication

Business impact

Following were the benefits realized by the client:

Cost savings of 47% due to the deployment of AWS
Transparent and usage driven ‘pay-per-use’ cost model
Reduced complaints from business and improved customer satisfaction
Data center space problems resolved
Capacity to deploy new services with the enhancements
Servers and storage solutions provisioning time reduced to less than 24 hours
Self-service portal enabled users to assume control
IT service is now perceived as more reliable and available
