ECS extensions
Elastic Compute Service (ECS) extensions are plugins that extend the features of ECS instances. They include driver extensions, application performance booster extensions (KeenTune), and CloudOps Orchestration Service (OOS) extensions for quickly installing software such as Docker, Java, and MySQL.
To use ECS extensions, you must have the AliyunECSExtensionsFullAccess system policy. Alibaba Cloud accounts have this system policy by default. If you use a Resource Access Management (RAM) user, contact an administrator of the Alibaba Cloud account to grant this system policy to the RAM user. For more information about how to grant permissions, see Manage RAM user permissions.
Network acceleration driver extensions
Extension | Scenarios and description | Installation method | Uninstallation support | Technical support |
eRDMA driver | Enable instances to drive eRDMA devices. This is the device driver for the eRDMA network interface card (ERI). It allows the operating system to detect and use eRDMA hardware. This enables you to experience a high-performance RDMA network service with ultra-low latency, high throughput, and high elasticity on your existing network. For more information about this feature, see eRDMA overview. | Configure eRDMA and test performance on an enterprise-level instance | Manual uninstallation is supported. | The software is developed in-house by Alibaba Cloud. Alibaba Cloud provides technical support. |
Application performance booster extensions
These extensions improve the performance of applications such as Nginx, MySQL, Redis, PostgreSQL, Memcached, x264, and x265.
Extension | Scenarios and description | Installation method | Uninstallation support | Technical support |
Performance booster | Improve application performance. Use KeenTune to perform full-stack performance tuning. This improves the performance of applications such as Nginx, MySQL, and Redis by about 20% on average. | Manual uninstallation is supported. For more information, see Accelerate application performance. | Application performance booster extensions include the installation of third-party open source software and configuration changes for performance tuning.

OOS extensions
ECS extensions are integrated with the extension feature of CloudOps Orchestration Service (OOS). This lets you quickly install various software extensions in batches on one or more ECS instances, such as Java, Python, MySQL, Docker, SVN, Grafana, and Simple Log Service. This feature improves the efficiency of software installation and uninstallation and simplifies complex program installation processes.
OOS extensions are published and maintained by CloudOps Orchestration Service (OOS). You can also create custom extensions.
Extension | Scenarios and description | Installation method | Uninstallation support | Technical support |
Public extensions | Solve software installation issues on ECS instances, such as installing Java, Python, Docker, server management software, and Simple Log Service. |
| One-click uninstallation is supported. | Alibaba Cloud provides technical support. |
Custom extensions | Meet requirements for specific application scenario configurations or personalized experiences. For example, use custom operating system or application extensions for flexible environment configuration, or use custom web browser extensions to enhance your personal browsing experience. |
| These are user-defined. Alibaba Cloud does not provide technical support. |
