General Availability: Azure SQL Database Basic, Standard, and Premium service tiers

2014年9月10日

Three new Azure SQL Database service tiers—Basic, Standard, and Premium—are generally available. The tiers target seven performance levels, so they're flexible enough for light to heavyweight workloads. You can look forward to:
  • 99.99 percent uptime SLA*, one of the highest for Azure services.
  • Hourly billing for greater flexibility and budget management.
  • Reduced prices (up to 50 percent from previously published generally available pricing).
Or, choose our new Standard performance level for a cost-effective solution that falls between Basic and S1. All general availability pricing for Basic, Standard, and Premium tiers will take effect on November 1, 2014.
