- Max endpoints per deployment: 25 input endpoints, 25 internal endpoints
- SLA: 99.95% (with two or more role instances in different fault and upgrade domains)
| Size | CPU | RAM | Disk |
|---|---|---|---|
| A8 | 8 @ 2.6 GHz(Intel® Xeon® E5-2670) | 56 GB (DDR3-1600 MHz) | 1,770 GB |

Notes
- PaaS only
- 10 Gbps Ethernet
- 40 Gbps back end, Remote Direct Memory Access (RDMA) capable.
- RDMA is only enabled through applications that use the Network Direct interface. (i.e. HPC Pack 2012 R2 on Windows Server 2012 or Windows Server 2008 R2. NOT supported on Windows Server 2012 R2)
- Only available in West Europe. (Feb 2014)
- Cannot be deployed by using a cloud service that is part of an existing affinity group. Likewise, an affinity group with a cloud service containing A8 or A9 instances cannot be used for deployments of other instance sizes.
- Number of Roles Allowed In Windows Azure Deployments Increased To 25
