The Business Challenge
The client wanted to build a dependable, robust and secure technology infrastructure that could:
- Facilitate script automation to eliminate manual process-related errors.
- Reduce the cost of operations as more bandwidth means more complexity and increased operational expense.
- Minimize downtime to prevent revenue loss as network outages significantly disrupt business operations, adversely impacting customer loyalty.
- Protect enterprise data to tackle the ever-increasing threat of cyberattacks and data breaches incidents.
- Scale the network to equip it for future 'on-demand' growth to manage changes in real-time.
- Enhance network performance through agile applications that can handle dynamic bandwidth needs and network topology changes.
Technology Components
- AWS Organization structure separated to departments with service control policy
- AWS-S3, EC2, AIM, Snapshots, EIP, NAT, AWS-VPC, Public-Private Subnets, NACLs, VPN, VGW, Endpoint Security Groups, IAM, Roles, Policy, MFA, SAML, AD Federated
- AWS WAF, AWS DDoS
- CloudTrail, CloudWatch
- Other Platforms: Jira 7, Splunk, Git bucket, Jenkins
The Approach
TSYS selected Trianz to build a continuous integration and continuous delivery (CI/CD) pipeline, which can automate the entire code deployment process.
Additionally, Trianz implemented the following solutions:
- Created PoC for multiple cloud framework models to meet business requirements for multiple lines of business.
- Developed the cloud agnostic automation process (Infrastructure as a Code) through scripts like Terraform, Python, Cloud formation, etc.
- Improved deliverables' efficiency, monitoring and infrastructure management.
- Enabled continuous delivery with built-in DevOps capabilities; integration with Jenkins and platforms/ tools identified and leveraged by the client within a cloud deployment.
- Guided the client on implementing industry best practices while meeting deliverables' timelines.
- Periodically reviewed architecture and provided necessary feedback towards (cost) optimization as per best practices and industry recommendations.
- Provided cloud support portal login to help the client raise support requests and get access to relevant information about the supported environment.
Transformational Effects
- Streamlined the new hire onboarding process using a single self-service offering and auto-routing of those requests, reducing manual effort.
- Implemented Enterprise Splunk on the cloud.
- Integrated on-prem cost model tool (Apptio) on the cloud using tagging technology.
- Enhanced visibility to software-hardware allocations and capacity monitoring.
- Operation Automation: The new CI/CD pipeline uses GitHub, CodeDeploy and CodePipeline to remove friction while deploying the new code. As a result, TSYS is now able to push small, incremental updates to its software, version control and documentation updates to match the pace of innovation.
- Enhanced Security: Organization and department segmentation with multi-factor authentication, active-directory federation control and least privilege access for developers.
- High-Availability: The implementation of Auto Scaling Groups, ec2, and network to handle spikes in traffic, snapshots and AIM usages to tackle immediate deployment or disaster recovery issues.
