A handful of cloud vendors set the price, get teams addicted to the surface area of proprietary services, and count on the switching cost being high enough that you stay.
Most people have stopped questioning it. Kubernetes clusters in the big clouds run at eight to ten percent utilization. A team spending $1M a year uses $80k of it.
Cloud native was supposed to fix this a decade ago but it didn't.
Spot is an open market for cloud servers. Users bid for machines, and a true market auction determines the price.
Prices are discovered by auction, not set by a vendor.
Servers, storage, networking, and a free managed control plane. No nickel-and-diming.
Virtual machines, Kubernetes, and serverless. Not two hundred services.
Idle compute resold at near-zero incremental energy cost.
Every server pool trades at a live price set by supply and demand.
You name the most you are willing to pay per node hour.
You pay the market's clearing price, which usually sits below your bid.
If the clearing price rises above your bid, your machines are pre-empted. In the past 2.5 years, 99.32% of bids ran without interruption.
Capacity is sold by auction, and the market sets the price.
Three ways to run a cloudspace.
Fully managed Kubernetes through your own kubeconfig and kubectl.
Storage classes, Calico networking, and load balancers, ready to use.
A30 and H100 classes with no upfront hardware.
Spin up market-priced VMs without a cluster.
Bring your own image and run whatever you like.
Bid per hour and pay the clearing price.
Serverless cloudspaces are coming soon.
Every cloudspace includes
Fully managed Kubernetes, consumed through your own kubeconfig and kubectl. No control-plane bill.
SSD and SATA storage classes, Calico networking, and load balancers, wired up and ready.
NVIDIA A30 and H100 classes for AI, machine learning, and analytics, with no upfront hardware.
Bring your own cluster, or start fresh.
Start clean on the free managed Kubernetes control plane and let the market price every node. This is where the savings are deepest.
Start freshPoint an existing EKS or similar Kubernetes environment at Spot to gain capacity on the cheap. Nothing to migrate, and the savings become available in the environment you already run.
COMING SOONSpin up a cloudspace and point a non-critical workload at preemptible nodes. Get a feel for the market.
Add your interruption handling and watch how the workload behaves when capacity shifts.
Move the steady-state load over once you trust it, and keep the on-demand pool for what cannot pause.
You write a little code to handle preemption, in exchange for radical savings.
Consume Spot with your choice of interface.
Provision and manage cloudspaces straight from your Go services.
View project →Declare Spot infrastructure as code alongside everything else you run.
View project →Drive the whole platform from your terminal and your pipelines.
View project →Hand Spot to your agents and let them stand up compute on request.
View project →"Spot helped us render videos at scale without going bankrupt as a bootstrapped company. Monthly expenditure compared to AWS dropped by 87%."
"We went from $4,000 for AWS for the three nodes to $50 a month. It was like night and day. A lot of people were singing my praises in the office — like, where did you find this? You get the same or similar reliability as DigitalOcean at a super cost."
"With Rackspace Spot and Kubernetes, we've deployed Airflow and run our workloads at a lower cost than other cloud providers."
"We use Spot to host large test and compiling infrastructures at a fraction of the expected cost, for a non-profit organisation."
"Rackspace Spot is the most cost-effective managed Kubernetes solution in the industry. Today it's fantastic for rapid prototyping and development."
"Spot is my first choice for stateless, compute-intensive workloads. The Terraform integration and hands-free Kubernetes management deliver massive value for the price."
"Spot is an awesome way to scale out your Kubernetes footprint without the high cost of the hyperscalers. Perfect for intermittent workloads like batch processing."
"Rackspace Spot offers revolutionary value for Kubernetes. My web services have a new home at Rackspace Spot."
"Spot lets me use Kubernetes for projects that can't support a full production cluster's budget. I recommend it to anyone learning Kubernetes who wants to deploy in the cloud instead of just minikube."
"Spot has given my solo startup a Kubernetes cluster to grow into at a liveable cost."
