PayMe, a leader in embedded finance and a PCI-certified financial services provider recognized for its long-standing credibility and excellence, is redefining how SMBs access financial services globally. To stay ahead, they needed an infrastructure as modern and efficient as the platform they deliver.

Author: Evgeny Lukashov, Cloud Solution Architect  

The Challenge  

PayMeโ€™s AWS environment was built on EC2 with Elastic Beanstalk and NAT Gateway routing traffic through the public internet. The setup was expensive, hard to manage, and lacked modern security monitoring. Threat detection was reactive, and maintaining the infrastructure was eating up valuable engineering cycles. 

What PayMe Needed 

โœ” Compute Modernization โ€“ Shift from legacy EC2 to a serverless container approach. 
โœ” Private Connectivity โ€“ Establish a secure, low-latency channel to their payment partner. 
โœ” Real-Time Security Visibility โ€“ Gain centralized, automated threat detection and alerting. 
โœ” Lower Operational Overhead โ€“ Eliminate patching, scaling, and instance management. 

The Solution  

2bcloud worked with PayMe to rebuild their infrastructure using modern AWS primitives that prioritized security, efficiency, and performance. 

Compute Modernization with ECS Fargate 

  • Migrated workloads from EC2 + Beanstalk to ECS Fargate to remove infrastructure management.ย 
  • Deployed ECS Service Discovery for more reliable inter-service comms.ย 
  • Streamlined deployments with CI/CD pipelines and auto-scaling, minimizing downtime.ย 

Private Network Connectivity 

  • Implemented AWS Direct Connect to securely link AWS with PayMeโ€™s Israeli payment processor.ย 
  • Eliminated NAT Gateway usage, reducing latency and data transfer costs.ย 
  • Encrypted, dedicated connection replaced flaky internet-based routing.ย 

Security Visibility and Threat Detection 

  • Enabled AWS GuardDuty org-wide to monitor threats across all accounts.ย 
  • Integrated with Slack and email for instant alerting.ย 
  • Moved ECS workloads to private subnets with strict security group rules.ย 

The Technical Stack

1๏ธโƒฃ ECS Fargate + Service Discovery 

  • No EC2 managementย 
  • Faster, more reliable inter-service trafficย 

2๏ธโƒฃ AWS Direct Connect 

  • Static latency, no public internet exposureย 
  • Cost savings on data transferย 

3๏ธโƒฃ AWS GuardDuty Integration 

  • Centralized threat detection across the orgย 
  • Alerts routed via Slack & email in real-timeย 

4๏ธโƒฃ CI/CD Pipeline Revamp 

  • GitHub Actions and IAM roles streamline deploymentsย 
  • Reduced release friction and overheadย 

The Results 

โœ” 30%+ cost reduction by cutting EC2 and NAT Gateway usage 

โœ” Significant drop in latency to the payment partner via Direct Connect 

โœ” Near-zero maintenance overhead with serverless infrastructure 

โœ” Real-time threat detection and centralized observability 

Why It Matters 

“As a PCI-certified financial platform, we continuously align our infrastructure to meet high compliance and performance standards. Migrating to ECS Fargate, eliminating NAT Gateway, and using Direct Connect was a strategic move that directly supports our platform’s scalability, and security needs to serve our customer’s best”.

Looking Ahead 

PayMe remains focused on maintaining enterprise-grade security while accelerating innovation. With infrastructure off their plate, PayMe’s engineering team is now fully focused on building features that matter to their users. Their platform is scaling securely and cost-efficiently, opening up more opportunities to serve global SMBs with faster, safer, and more reliable embedded finance solutions.
