Cloud-Native Infrastructure ​

The Simple Platform is built on a foundation of modern, battle-tested, cloud-native technologies. Our infrastructure is designed from the ground up for high availability, elastic scalability, and deep observability, ensuring your mission-critical applications are always performant and reliable.

High Availability on Kubernetes (GKE) ​

The entire platform runs on Google Kubernetes Engine (GKE), leveraging its powerful orchestration capabilities to deliver resilience and scale.

  • Multi-Zone Architecture: Our services are deployed across multiple availability zones within a region. This design ensures that the failure of a single zone — or even an entire data center — will not impact the platform's availability.
  • Automated Scaling: We utilize Kubernetes' Horizontal Pod Autoscaler and GKE's Cluster Autoscaler to dynamically add or remove resources based on real-time demand. This ensures you always have the performance you need, without paying for idle infrastructure.
  • Intelligent Scheduling: We employ pod anti-affinity and topology spread constraints to ensure that critical service replicas are distributed across different physical machines and zones, further enhancing fault tolerance.

Massive Concurrency with Elixir & OTP ​

Our core backend services (Data API Gateway, Trigger, Identity, Metadata) are written in Elixir, running on the Erlang VM (OTP). This is not an arbitrary choice; it is a strategic decision to leverage one of the most robust and scalable runtime environments ever created.

  • Extreme Concurrency: The BEAM VM is famous for its ability to handle millions of lightweight, concurrent processes. This makes it the perfect foundation for our event-driven architecture, allowing the Trigger Service to process a massive volume of simultaneous database events, webhooks, and scheduled tasks without breaking a sweat.
  • Fault Tolerance & Self-Healing: OTP's "let it crash" philosophy and supervision trees mean that if an isolated part of a service fails, it is automatically restarted in a known good state without bringing down the entire service. This provides a level of resilience that is difficult to achieve in other runtimes.

Zero-Trust Networking with a Service Mesh ​

We operate on a zero-trust security model. We assume no internal traffic is safe by default. To enforce this, we use Linkerd, a lightweight, high-performance service mesh.

  • Automatic mTLS: Linkerd automatically encrypts and authenticates all communication between our microservices using mutual TLS (mTLS). This means every internal API call is secure, preventing eavesdropping or request spoofing within the cluster.
  • Secure by Default: Because mTLS is managed by the mesh at the infrastructure layer, security is automatic and does not depend on developers remembering to implement it in application code.

High-Performance Networking & Observability with eBPF ​

To achieve both best-in-class network performance and deep, real-time insights, we leverage eBPF (Extended Berkeley Packet Filter) at the core of our Kubernetes networking fabric.

  • Kernel-Level Networking: eBPF allows us to implement advanced networking logic — such as load balancing, policy enforcement, and routing — directly within the Linux kernel. By bypassing traditional, slower kernel networking paths (like iptables), we significantly reduce network latency and CPU overhead for service-to-service communication.
  • Deep Observability without Overhead: The same eBPF foundation provides unparalleled, fine-grained visibility into network traffic, application behavior, and system calls. Unlike traditional monitoring agents that can consume significant resources, eBPF gathers deep metrics with near-zero performance impact. This allows us to monitor every aspect of the platform continuously, ensuring we can detect and diagnose issues before they impact users.

By combining a service mesh for security with eBPF for networking and observability, the Simple Platform achieves a networking architecture that is simultaneously secure, highly performant, and deeply transparent.
