As answered by people managing c12n.cloud and Framz Cloud Cost.
c12n.cloud's answer
c12n is the only open-source cloud solution integrating end-to-end GitOps automation with OpenStack, Kubernetes and Ceph. c12n is highly scalable, secure and requires minimum day-2 Ops.
Framz Cloud Cost's answer:
The price is fixed and the evidence is published. £499 for the audit, and free if it does not find at least 20% of your monthly AWS spend. About 70 automated checks run against a read-only role, then a person verifies every finding before it reaches the report.
We ran the same scanner against our own AWS account before selling it to anyone. It found $293.82 a month of savings on $8,746.75 of spend, which is 3.4% and fails our own guarantee. The whole result is published unedited at cloud-cost.framz.io/demo.
c12n.cloud's answer
Why pay for VMware when you can have 80% of its functionality for free? c12n is 100% Open Source and 100% Automated with 0% License fees. c12n puts you back in control of your own sovereign Infrastructure as a Service (IaaS), it is designed to be vendor-lock free, giving you the freedom to choose your support providers or even operate the platform with your own in-house expertise like some customers do.
Framz Cloud Cost's answer:
Most products in this category sell a dashboard and leave the deciding to you. This produces a report you can act on: every finding names the resource, what it costs today, what the fix saves, the risk, the effort, and the evidence the number came from, sorted by saving against effort.
Pricing is a flat £499 rather than a percentage of spend or a per-seat licence, so the cost does not scale with the size of the problem. Twelve of the calculators behind the checks are free with no signup, and the full audit checklist is published, so a first pass costs you nothing.
c12n.cloud's answer
Managed Service Providers (MSP), cloud providers and literally any organization that wants to run their own cloud either due to security & legal requirements or to reduce costs compared to public cloud or proprietary solutions such as VMware and Nutanix.
Framz Cloud Cost's answer:
UK companies spending roughly £2,000 to £30,000 a month on AWS, usually between 10 and 100 people. The person who gets in touch is normally a CTO, a head of engineering or a founder who suspects the bill is too high and has nobody whose job it is to check. Most common shapes: SaaS products, software agencies, e-commerce, fintech and data teams.
c12n.cloud's answer
The team behind c12n has been working with Openstack for more than 10 years. Tools such as Kubernetes and ArgoCD gave us a completely new set of possibilities to deploy, upgrade and operate OpenStack and Ceph in a highly efficient way. Since 2017 we’ve been running the first OpenStack installation on Kubernetes and quickly realized the power of such a combination.
Framz Cloud Cost's answer:
We built the scanner to answer the question for ourselves. Before charging anyone for it we pointed it at our own AWS account, and it came back with 3.4%, below the threshold we now guarantee. We published all 105 findings resource by resource anyway, because a mocked-up dashboard proves nothing and a real result that fails our own test proves the scanner is not flattering us.
The pricing came from the same reasoning. A fixed £499 with a guarantee means the incentive is to find real money once, rather than to keep a subscription running.
c12n.cloud's answer
The power behind c12n lies in its foundation of proven open-source technologies. At its core is OpenStack, a free, open standard cloud computing platform that provides all major IaaS features and has a global footprint of over 45.000.000 compute cores.
This is complemented by Kubernetes, the leading container orchestration platform, and Ceph, a distributed software-defined storage platform capable of holding 50 PB+ of data. We also integrate ArgoCD for Continuous Delivery, Prometheus for comprehensive monitoring, and MAAS for managing the lifecycle of bare-metal.
Framz Cloud Cost's answer:
Next.js App Router on AWS Amplify Hosting, TypeScript throughout. The scanner is an AWS Lambda deployed with SAM that assumes a read-only cross-account IAM role in the client account and runs its checks against the Cost Explorer, Compute Optimizer, CloudWatch and resource APIs. MongoDB Atlas for storage with findings encrypted at rest, Amazon SES for email, Cal.com for booking.
