为 Azure Database for MySQL 计算资源预付预留容量Prepay for Azure Database for MySQL compute resources with reserved capacity

05/20/2020

本文内容

与即用即付价格相比,Azure Database for MySQL 现在可为计算资源事先预付节省资金。Azure Database for MySQL now helps you save money by prepaying for compute resources compared to pay-as-you-go prices. 利用 Azure Database for MySQL 预留容量,你可以在一年或三年期限内提前提交 MySQL 服务器,以获得有关计算成本的重要折扣。With Azure Database for MySQL reserved capacity, you make an upfront commitment on MySQL server for a one or three year period to get a significant discount on the compute costs. 若要购买 Azure Database for MySQL 保留容量,需要指定 Azure 区域、部署类型、性能层和术语。To purchase Azure Database for MySQL reserved capacity, you need to specify the Azure region, deployment type, performance tier, and term.

不需要将保留分配给特定 Azure Database for MySQL 服务器。You do not need to assign the reservation to specific Azure Database for MySQL servers. 已在运行的 Azure Database for MySQL 或新部署的,将自动获得预留价格的好处。An already running Azure Database for MySQL or ones that are newly deployed, will automatically get the benefit of reserved pricing. 购买预留容量便会预付为期一年或三年的计算资源费用。By purchasing a reservation, you are pre-paying for the compute costs for a period of one or three years. 购买保留后,与预订属性匹配的 Azure database for MySQL 计算费用将不再按即用即付费率收费。As soon as you buy a reservation, the Azure database for MySQL compute charges that match the reservation attributes are no longer charged at the pay-as-you go rates. 预订不涉及与 MySQL 数据库服务器相关联的软件、网络或存储费用。A reservation does not cover software, networking, or storage charges associated with the MySQL Database server. 在保留期结束时,计费权益过期,按即用即付价格对 Azure Database for MySQL 进行计费。At the end of the reservation term, the billing benefit expires, and the Azure Database for MySQL are billed at the pay-as-you go price. 虚拟机预留实例不自动续订。Reservations do not auto-renew.

可以在 Azure 门户中购买 Azure Database for MySQL 保留容量。You can buy Azure Database for MySQL reserved capacity in the Azure portal. 通过提前付款或按月付款的方式为预留付款。购买保留容量:To buy the reserved capacity:

对于至少一个企业或个人订阅,你必须以即用即付费率作为所有者角色。You must be in the owner role for at least one Enterprise or individual subscription with pay-as-you-go rates.

对于企业订阅,必须在 EA 门户中启用“添加预留实例”。For Enterprise subscriptions, Add Reserved Instances must be enabled in the EA portal. 或者,如果禁用了该设置,则必须是订阅的 EA 管理员。Or, if that setting is disabled, you must be an EA Admin on the subscription.

对于云解决方案提供商 (CSP) 计划中,只有管理员代理或销售代理才能购买 Azure Database for MySQL 保留容量。For Cloud Solution Provider (CSP) program, only the admin agents or sales agents can purchase Azure Database for MySQL reserved capacity.

在购买之前确定正确的数据库大小Determine the right database size before purchase

保留的大小应基于特定区域中现有或即将部署的服务器使用的计算总量,并使用相同的性能层和硬件生成。The size of reservation should be based on the total amount of compute used by the existing or soon-to-be-deployed server within a specific region and using the same performance tier and hardware generation.

例如,假设你正在运行一个通用的 Gen5 – 32 vCore MySQL 数据库,以及两个内存优化的 Gen5-16 vCore MySQL 数据库。For example, let's suppose that you are running one general purpose, Gen5 – 32 vCore MySQL database, and two memory optimized, Gen5 – 16 vCore MySQL databases. 接下来,假设你计划在下个月中部署一个额外的常规用途: Gen5 – 32 vCore 数据库服务器和一个内存优化的 Gen5 – 16 vCore 数据库服务器。Further, let's supposed that you plan to deploy within the next month an additional general purpose, Gen5 – 32 vCore database server, and one memory optimized, Gen5 – 16 vCore database server. 假设你知道,你将需要至少1年的这些资源。Let's suppose that you know that you will need these resources for at least 1 year. 在这种情况下,你应该购买 64 (2x32) Vcore,1年保留用于单个数据库常规用途-Gen5 和 48 (2x16 + 16) vCore 1 年保留用于单个数据库内存优化-Gen5In this case, you should purchase a 64 (2x32) vCores, 1 year reservation for single database general purpose - Gen5 and a 48 (2x16 + 16) vCore 1 year reservation for single database memory optimized - Gen5

购买 Azure Database for MySQL 保留的容量Buy Azure Database for MySQL reserved capacity
