About Cozystack

Cozystack is a free cloud platform based on Kubernetes. It is used to build a cloud or provide development environments. It transforms bare metal servers into a system with a REST API for spawning Kubernetes clusters, databases, virtual machines, load balancers, and HTTP caching services. It is a Cloud Native Computing Foundation Sandbox project.

How to evaluate Cloud Platforms & IaaS

This is how the CIOPages Research Team evaluates this category. It is not an assessment of Cozystack. It comes from our Cloud Infrastructure & IaaS buyer guide.

25%

Compute, AI Silicon & Scaling

Instance-family breadth (general, compute, memory, ARM/Graviton-class), serverless and container compute, spot/preemptible pricing, and — increasingly decisive — GPU and custom-accelerator availability (Nvidia plus Trainium/TPU/Maia), reserved AI capacity, and queue priority for scarce silicon

20%

Networking & Data Egress

VPC/VNet design, private connectivity (Direct Connect / ExpressRoute / Interconnect / FastConnect), DDoS and edge protection, and the egress and inter-region transfer model — per-GB rates, free allowances, and how the provider prices moving data out, which is where multicloud and chatty architectures get expensive

20%

Storage & Data Services

Object/block/file storage with durability and lifecycle tiering, managed relational/NoSQL/in-memory databases, data-lake and warehouse integration, cross-region replication and backup/DR — and how deeply these proprietary services would entangle your applications

15%

Security, Compliance & Sovereignty

Identity and key-management depth, zero-trust networking, certification breadth (SOC 2, ISO 27001, HIPAA, FedRAMP, PCI-DSS), and data-residency and sovereign options — EU-operated entities, sovereign regions, national qualifications — plus a clear-eyed view of which jurisdiction’s law can compel access

10%

Management, Operations & FinOps

Console and API quality, Infrastructure-as-Code support (Terraform, Pulumi, CloudFormation/Bicep), observability, and native cost-management, tagging, and commitment-tracking tooling — because operating and governing the spend is a daily cost, not a one-time setup

10%

Ecosystem, Support & Commercial Fit

Partner and marketplace depth, training and talent availability, enterprise support tiers and their real cost, region/availability-zone footprint where you operate, and the commercial terms underneath it all — committed-use discount structure, enterprise agreement leverage, and exit/portability clauses
