Rackspace Spot - Pricing
Cloud pricing is notoriously complex: rife with hidden complexities and unexpected fees. Our goal with Rackspace Spot is to offer an unbeatable value proposition, while also keeping the model simple and predictable.
Pricing Philosophy
- Compute capacity is priced dynamically, based on an open market auction (subject to a base price of $0.001 / hr). Price for instances is set by lowest bid for compute that can be fulfilled by available capacity
- Add-ons such as highly available control plane, persistent volumes, load balancers and others are priced with a simple, predictable model
- All resources are billed to the second, based on usage during a month
Pricing Summary Resource
| Resource | Model | Price / Unit |
|---|---|---|
| Compute Servers | Open Market Auction | From $0.001 / hr (varies by type). Minimum bid accepted is current market price, or reserve price, whichever is higher. |
| Persistent Volumes | Fixed | ssd - $0.06 / GB-mo ssdv2 - $0.06 / GB-mo sata - $0.02 / GB-mo ssdv2-performance - $0.06 / GB-mo |
| Bandwidth - Ingress | No cost | |
| Bandwidth - Cross-region | No cost | |
| Bandwidth - Egress | Fixed allowance + Variable for excess | Allowance of 100 GB-mo per GB of Compute RAM. Additional egress - $0.01 / GB |
| Load Balancers | Fixed | $10 / mo |
| Cloudspace Control Plane | Fixed | Highly available control plane - $40 / mo |
| Cloudspace Add-Ons | Fixed | Varies |
Compute Pricing
Compute capacity is priced dynamically based on an open market auction. All compute flavors in all regions are subject to a minimum base price that varies by their age, capacity and value. The lowest base price is $0.001 per hour; i.e. 0.1 cents per hour. The actual price for any instance at any given point in time will vary, and is determined by the lowest price determined by Open Market Auction. See Cloud Server Classes for the configurations of available cloud servers by region.
Compute Comparison vs Equivalent Hyperscaler Prices
Spot makes it easy to compare the current price for a server class VS the equivalent price from the 3 leading Hyperscalers (AWS, Azure and GCP). To view this information, select your preferred server class and click "What should I bid?":
Factors Included in Comparable Prices
Cloud pricing is notoriously complex, and various factors such as add-on fees (e.g. egress fees), the availability of various added services (e.g. PaaS services), and regional availability can make it hard to compare on a true apples-to-apples basis.
The Comparable prices interface is not perfect, since it is impossible to take all of these factors into consideration and there may be a lag in the rate at which the comparable hyperscaler prices are updated. However, these factors are taken into account in showing the comparable price:
- Spot instances pricing from Hyperscalers. Savings shown are savings vs Spot server pricing from Hyperscalers
- Same or nearly identical region
- Same or nearly identical hardware generation
- Same or nearly identical CPU
- Same or nearly identical Memory
Billing for compute instances
Compute servers are billed from the time when they are provisioned for a winning bid, power up, and reach the READY status in the Kubernetes control plane. In other words, servers are not billed if:
- The bid for servers didn't win in the market auction
- The bid won in the market auction but servers failed to provision or power up
- Servers took too long to provision (such instances are treated as failed instances)
- Servers powered on but couldn't successfully become READY as seen by the Kubernetes control plane (due to any reason)
Persistent Volumes
Persistent volumes are creating by a persistent volume claim that references an available storage class:
Please note that persistent volumes are billed as long as they exist. Unbound volumes will continue to incur costs until they are deleted.
Bandwidth - Ingress (Inbound data transfer)
Inbound data transfer is free without any additional charges.
Bandwidth - Cross-region traffic
Cross-region data transfer, within Rackspace Spot data-centers, is free without any additional charges.
Bandwidth - Egress (Outbound data transfer)
Every organization gets an allowance for free outbound data transfer. This allowance scales with the amount of server infrastructure used by the organization (across one or more Cloudspaces). Outbound data transfer beyond that allowance is billed at $0.01 / GB.
Outbound data transfer allowance per month = (avg. amount of compute server GB used in month) * 100 GB
Outbound data-transfer beyond the included allowance is billed at $0.01 / GB.
Load Balancers
Load balancers can be created by creating a Kubernetes service of type "LoadBalancer". Load balancers cost $10 / mo. See Load Balancers for more details
Cloudspace Control Plane
Non-production control planes have fewer resources allocated to them, and are not intended to be highly available. Non-production control planes are free.
Production control planes have greater resources, and are designed to be highly available. Production control planes cost $40 / mo. See (Link Removed) for more details
Cloudspace Add-Ons
Cloudspaces will offer a variety of additional add-on services. The pricing of each add-on will vary, and will be specified as they become available.
