Choosing the Right Infrastructure Approach

Kubernetes is a powerful orchestration platform. It is also one of the most misapplied infrastructure tools in use today. The decision to adopt Kubernetes -- or any infrastructure approach -- should be based on concrete operational requirements, not industry trends.

This post provides a framework for making that decision and shows how Puchify supports each approach.

The Kubernetes Operational Cost

Before adopting Kubernetes, evaluate what it requires:

Cluster management. The control plane needs ongoing attention. Version upgrades, etcd backups, CNI plugin configuration, and node health management are recurring tasks. A three-node cluster requires more operational overhead than ten standalone servers.

Team expertise. Someone on the team needs to understand the scheduler, API server, controller manager, and their interactions during failure scenarios. This knowledge is specialized and takes time to develop.

Abstraction overhead. Kubernetes adds layers of abstraction -- Pods, Services, Deployments, Ingresses, NetworkPolicies -- that must be understood and maintained. Each layer is a potential failure point and a source of cognitive load.

For teams of fewer than six engineers running fewer than six services, this overhead rarely provides commensurate value.

When Kubernetes Makes Sense

Kubernetes delivers value when:

Multiple services require independent scaling. The scheduler can allocate resources dynamically across services with different load profiles. An API server, worker pool, WebSocket service, and batch processor can share a node pool, with each service scaling based on its own metrics.

The team has dedicated infrastructure engineers. At a team size of six or more, the operational overhead of Kubernetes can be assigned to specific team members. The cost of cluster management is amortized across the organization.

Multi-tenancy with isolation is required. Namespace-level resource quotas, network policies, and RBAC provide isolation that is difficult to achieve with standalone servers.

Complex traffic management is needed. Service mesh, mTLS, fine-grained ingress rules, and canary deployments are easier to implement with Kubernetes than with alternative approaches.

Simpler Alternatives

For most teams, one of these approaches is more appropriate than Kubernetes.

Single Server with Docker

A single server running Docker with systemd provides process supervision, logging, automatic restarts, and straightforward management. This setup handles significant traffic when the server plan is scaled appropriately.

Server with Managed Database

This is the recommended default for most projects. One server handles the application and reverse proxy. A managed database handles persistence with automated backups and credential rotation. Object storage handles file assets.

This stack scales vertically to handle millions of requests per day. Upgrading the server plan and adding database read replicas are single API calls.

Decision Framework

Use this table to determine the right approach:

Condition	Recommended approach
1-3 services, team of 1-3	Single server + managed database
3-6 services, team of 3-6	Multiple servers or managed containers
6+ services, team of 6+	Kubernetes
Complex networking requirements	Kubernetes or dedicated networking resources
Multi-tenant workloads	Kubernetes with namespace isolation
GPU workloads	Dedicated GPU server or Kubernetes with GPU node group

How Puchify Supports Each Path

Puchify does not require a specific infrastructure approach. You can provision a single server and a database, or a multi-node Kubernetes cluster, or any combination of resources. All resources share the same API, authentication, and management interface.

Start with the simplest approach that meets your current requirements. Add complexity when your operational needs justify it. Change your approach without changing your infrastructure provider.
