Introduction:
This company stands out as the leading electronic payment services provider in Iraq country. The company issues and acquires payment cards, including international options, on behalf of multiple affiliated banks including government banks within the country. This company’s cutting-edge solution leverages biometric identification to verify cardholders. Their widely used system distributes pensions, social welfare aid, and employee salaries to millions of customers through a massive network of 6000 service points nationwide.
The Challenge:
Timelines:
Understanding the infra was a big challenge as the landing zones are to be created.
After having comprehensive discussions between Teleglobal and the stakeholders the conclusion has been derived that the dev and test environment should be deployed on AWS while the Pre-Production and Production environments should be deployed on-premises.
Understanding the Infra: 10-15 days (about 2 weeks)
Cloud Deployment (dev + test): 4 months
On-Premises Deployment (pre-prod + Prod): 6 months
Cost Optimization: 2 months
The Solution:
Our team devised a comprehensive strategy to address the client’s requirements, focusing on efficient landing zone creations, AWS service deployments, including deployments of huge amount of pipelines, all under strict cost optimization measures.
The plan was devised to deploy dev/test environments onto the AWS cloud and the pre-production and Production workloads onto on-premises in order to achieve both cost savings and PCI-DSS rules and regulations adherence.
On-Premises Infrastructure (Pre-prod and Production):
An amazing infrastructure was devised from the scratch for the deployment of production workload on on-premises.
The below are some of the components of the architecture our team devised:
Creation of Landing Zones:
Various OUs (organizational Units) were created using various AWS services to manage certain areas of concerns like Security, Logging, Monitoring, etc., centrally
AWS Infrastructure (Dev/Test):
Below is the list of some of the resources that our team deployed for dev/test workloads to run:
By going through the Hybrid strategy Teleglobal specifically devised, this Financial Giant was saved from overspending more than 2.5-3 million dollars per month on their infrastructural cost.
Cost-Optimized Deployment to the AWS Cloud:
Landing zones, where dev/test workloads were deployed, were planned wisely to optimize costs, if not configured up to the mark, may lead to an increase in compliance and security expenses. The setup of the landing zone included integration with identity directories,
formulation of account structures, establishment of virtual private cloud (VPC) networking, establishment of infrastructure for security, monitoring, and configuration management OUs.
Various options with reference to sizes and types were considered.
We made use of tools and monitoring to modify resource allocation based on authentic usage patterns.
Utilized S3 Intelligent-Tiering to automatically optimize storage costs by moving objects between frequent access and infrequent access tiers based on access patterns.
This granular data was then visualized through CloudWatch dashboards, allowing us to identify containers consistently underutilizing their allocated resources.
By skillfully right-sizing EKS worker node capacity based on the optimized container density, we achieved a 15-20% reduction in EKS costs (approximately $30,000 per month) applied on 2 various environments (dev, test) with 35+ EKS clusters, 200+ EKS worker nodes and 2000+ containers running 35+ microservices in them.
Seamlessly deployed the company’s dev/test infrastructure to the cloud, optimizing resource utilization and minimizing downtimes.
By understanding the architecture in and out and thus coming up with these personalized cost optimized solutions our team helped in saving up to $400-500K/month.
Outcomes:
Through our expertise, the leading Finance company successfully transitioned to a cloud-native infrastructure, realizing substantial cost savings and operational efficiencies.
Through our expertise the Giant was able to deploy their 2 million worth cloud infrastructure on AWS cloud and 3 million worth infrastructures on On-premises environment.
After applying all the above strategies and cost optimization techniques their 2-million-dollar AWS cloud infrastructure cost came down to roundabout $1.5 million dollars per month.
Conclusion:
Our DevOps expertise, with a focus on cost optimization, empowered our Finance client to confidently navigate their digital transformation. We leveraged AWS cloud services to achieve significant cost savings, ranging from $400,000 to $450,000 per month, representing a 20-22% reduction in their overall cloud spend. This approach, combining DevOps agility with cost control, not only optimized their cloud infrastructure but also provided the foundation for enhanced service delivery and innovation. By embracing the power of the cloud and DevOps, we positioned our client for sustainable growth within the dynamic Finance landscape of Iraq.
