ECS de precio de spot
Concepto
Huawei Cloud vende los recursos informáticos disponibles con un descuento. El precio cambia en tiempo real dependiendo de las demandas del mercado. Este es el precio de modo de facturación al contado.
Un ECS facturado con precio de spot es un ECS de precio de spot.
En el modo de facturación de precios de spot, puede comprar y usar ECSs a un precio de descuento. El rendimiento de los ECS de precio de spot es el mismo que el de los ECS con las mismas especificaciones en otros modos de facturación. Sin embargo, cuando los recursos de inventario son insuficientes, o el precio de mercado aumenta y excede el precio esperado, el sistema liberará automáticamente sus recursos de ECS y recuperará los ECS. En comparación con los ECS de pago por uso y anual/mensual, los ECS de precio de spot ofrecen el mismo nivel de rendimiento a la vez que a costos más bajos.
Reglas de funcionamiento
El precio de mercado para los ECS de una cierta variante fluctúa debido a los cambios de oferta y demanda. Puede comprar y usar ECS de precio de spot a un precio de mercado bajo para reducir los costos de cómputo.
Al comprar un ECS de precio de spot, usted está obligado a establecer el precio máximo que está dispuesto a pagar por un sabor específico. Un precio más alto asegura una mayor tasa de éxito para que usted compre este tipo de ECS.
- Si el precio máximo es mayor o igual que el precio de mercado y los recursos de inventario son suficientes, se compra el precio de spot ECS. El ECS se factura al precio de mercado.
- Si el precio máximo es inferior al precio de mercado, el precio de spot ECS no se puede comprar.
Después de comprar un ECS de precio de spot, puede usarlo como usar los ECS en otros modos de facturación. Sin embargo, el sistema comparará periódicamente el precio máximo con el precio de mercado y comprobará los recursos de inventario.
- Si el precio máximo es mayor o igual que el precio de mercado y los recursos de inventario son suficientes, puede continuar usando el ECS.
- Si el precio máximo es menor que el precio de mercado o los recursos de inventario son insuficientes, el sistema le notifica la liberación de los recursos de ECS (la notificación está habilitada) y elimina automáticamente el ECS en unos 5 minutos.
Escenarios de la aplicación
- ¿Qué son compatibles?
Los ECS de precio de spot son adecuados para renderizado de imágenes, servicio web sin estado, secuenciación génica, análisis fuera de línea, cálculo de funciones, cálculo por lotes, análisis de muestras, CI/CD y pruebas.
NOTA:Cuando el precio de mercado es más alto que el precio máximo que está dispuesto a pagar o los recursos de inventario son insuficientes, el precio de spot ECS será reclamado. Por lo tanto, realice una copia de seguridad de los datos cuando utilice dichos ECS.
- ¿Qué no son compatibles?
Para evitar que la reclamación de ECS interrumpa los servicios, no utilice los ECS de precio de spot para ejecutar los servicios que requieren operaciones a largo plazo o alta estabilidad.
Notas
- Solo los ECS de KVM admiten pagos de precios de spot. Para obtener más información acerca de los sabores ECS, consulte la información que se muestra en la consola de gestión.
- Los precios de mercado de los ECS de la misma variante pueden variar dependiendo de AZ.
- Los ECS de precio de spot no soportan el cambio del sistema operativo.
- Los ECS de precio de spot no soportan la recuperación automática.
- Los ECS de precio de spot no soportan la modificación de las especificaciones.
- Los ECS de precio de spot no se pueden crear con una imagen de Marketplace.
- Los ECS de precio spot no se pueden cambiar a ECS anual/mensual.
- Cuando un ECS de precio de spot está siendo reclamado,
- No se puede utilizar para crear imágenes de disco del sistema e imágenes ECS completas. Sin embargo, los discos de datos del ECS se pueden usar para crear imágenes de disco de datos.
- No se puede borrar.
- De forma predeterminada, los discos de datos y EIP de un ECS de precio de spot no se liberarán después de que se recupere. Si desea que se le notifique cuando se reclama un ECS puntual para que pueda determinar si desea liberar manualmente discos de datos y EIP, establezca una notificación de reclamación. Para obtener más información, consulte Compra de un ECS de precio de spot.
Regla de facturación:
Para obtener más información, consulte Facturación.
Ejemplos de facturación
- Si el precio de mercado es más alto que el precio máximo establecido, se libera el ECS de precio de spot. Se factura el ECS de spot de acuerdo con el precio de mercado. Ejemplo:
A las 08:30, el precio de mercado es de $0.02 USD/hora, y el precio máximo es de $0.04 USD/hora. Luego, el ECS se factura a $0.02 USD/hora.
A las 09:00, el precio de mercado es de $0.03 USD/hora.
A las 10:00, el precio de mercado es de $0.04 USD/hora.
A las 10:30, el precio de mercado es de $0.05 USD/hora, que es más alto que el precio máximo. A continuación, el sistema notifica al usuario la liberación de ECS.
Este ECS se factura en tres períodos de facturación.
Durante las 08:30-09:00, el ECS había estado funcionando durante 30 minutos y se factura por el segundo: 0.02/3600 x 30 x 60 = $0.01 USD
Durante 09:00-10:00, el ECS había estado funcionando durante 1 hora y se factura al precio de transacción a las 09:00, que es de $0.03 USD/hora.
Durante 10:00-10:30, el ECS había estado funcionando durante 30 minutos y se factura por el segundo: 0.04/3600 x 30 x 60 = $0.02 USD
El precio total es de $0.06 USD por una duración de 2 horas.
- Si los recursos de inventario son insuficientes, el sistema libera un ECS de precio de spot y lo factura en función del precio de mercado. Ejemplo:
A las 08:30, el precio de mercado es de $0.02 USD/hora, y el precio máximo es de $0.06 USD/hora. Luego, el ECS se factura a $0.02 USD/hora.
A las 09:00, el precio de mercado es de $0.03 USD/hora.
A las 10:00, el precio de mercado es de $0.04 USD/hora.
A las 10:30, el precio de mercado es de $0.05 USD/hora. Aunque el precio de mercado es más bajo que el precio máximo, el sistema lanza este ECS debido a recursos de inventario insuficientes.
Este ECS se factura en tres períodos de facturación.
Durante las 08:30-09:00, el ECS había estado funcionando durante 30 minutos y se factura por el segundo: 0.02/3600 x 30 x 60 = $0.01 USD
Durante 09:00-10:00, el ECS había estado funcionando durante 1 hora y se factura al precio de transacción a las 09:00, que es de $0.03 USD/hora.
Durante 10:00-10:30, el ECS había estado funcionando durante 30 minutos y se factura por el segundo: 0.04/3600 x 30 x 60 = $0.02 USD
El precio total es de $0.06 USD por una duración de 2 horas.
Compra de un ECS de precio de spot
Puede comprar un ECS de precio de spot en la consola de gestión o llamando a las API.
- Para obtener instrucciones sobre cómo comprar un precio de spot ECS en la consola de gestión, consulte Compra de un ECS de precio spot.
- Para obtener instrucciones sobre cómo comprar un precio de spot ECS llamando a las API, consulte "Creación de un ECS" en Referencia de la API de Elastic Cloud Server.
Recuperación de un ECS
Huawei Cloud puede reclamar y cancelar su ECS de precio de spot en cualquier momento. Un ECS de precio de spot que se está recuperando no se puede utilizar para crear imágenes.
La reclamación puede deberse a:
- Precio de mercado más alto que el precio máximo que está dispuesto a pagar
- Recursos de inventario insuficientes
NOTA:
- Si un ECS de precio de spot se reclama dentro de la primera hora después de que se aprovisiona, el precio de spot ECS no se factura.
- En el primer período de liquidación (en horas) de un precio de spot ECS, el precio de spot ECS se factura, independientemente de si se ejecuta.
- El tiempo necesario para reclamar un precio de spot ECS es de 5 minutos. Durante la recuperación, si se supera el reloj agudo, el ECS de precio de spot se factura al precio de mercado para el tiempo después del reloj agudo.
- Durante el funcionamiento de un ECS de precio de spot, su precio se actualiza una vez por hora. Después de que un ECS de precio de spot se reinicia, o se detiene y luego se inicia, se factura al precio de mercado cuando se inicia el ECS.
Copia de seguridad de datos sobre ECSs de precio de spot. Antes de que el sistema reclame su ECS de precio de spot, le notificará de la liberación de recursos si la notificación está habilitada. Utilice uno de los métodos siguientes para habilitar la notificación:
- Método 1: Utilice los metadatos de spot. Para obtener más información, consulte Obtención de metadatos.
- Método 2: Utilice Cloud Trace Service (CTS) y Simple Message Notification (SMN) proporcionados en la nube pública. Para obtener más información, consulte Compra de un ECS de precio de spot.
