Resource Orchestration Service (ROS) allows you to model and configure your Apsara Stack resources.

After you create a template that defines your required resources (such as ECS and RDS instances), ROS creates and configures these resources based on the template, facilitating resource management. ROS has the following benefits:

Infrastructure as Code

ROS is an Infrastructure as Code (IaC) solution provided by Alibaba Cloud to quickly implement IaC as a key component of DevOps.

Fully managed automation service

ROS is a fully managed service and does not require you to purchase the resources that are used to maintain your templates, allowing you to focus on maintaining the resources of your business and the template specifications. When you need to create multiple projects that are distributed across multiple stacks, managed automation of the creation process enables you to complete tasks faster. We recommend that you use ROS API operations to maintain stacks and use source code versioning software such as Git and SVN for centralized management of templates.

Repeatable deployment

You can use the same templates to deploy resources to the development, test, and production environments. You can set parameters to different values for different environments. For example, you can set the number of ECS instances in the test environment to 2 and the number of ECS instances in the production environment to 20. You can also use the same templates to deploy resources to multiple regions. This improves the efficiency of multi-region deployment.

Standardized deployment

In practice, subtle differences in different environments often lead to complicated management and high costs, prolong troubleshooting time, and interfere with the normal operation of your business. By using ROS for repeated deployment, you can standardize deployment environments, minimize the differences between different environments, and build environment configurations into templates. A rigorous management process similar to code implementation can ensure standardized deployment practices.

Unified authentication, security, and audit

Compared with other similar services, ROS provides better integration with other Apsara Stack services. Integration with Resource Access Management (RAM) provides unified authentication, eliminating the need to establish a separate user authentication system. Operations on all cloud services are called through APIs. You can use ActionTrail to review all O&M operations, including operations on ROS.
