Containers Enhanced Features

Application Management

FusionInsight RTD deploys Tomcat clusters and distributes BLUs, and also monitors the Tomcat clusters and BLUs.

After obtaining an application developed by a service developer, the system administrator can easily and quickly deploy the application to a cluster with the UI.

Service Governance

Developers can quickly develop RESTful services in BLUs. FusionInsight RTD manages services provided by BLUs, including controlling service access, managing load balancing policy, and performing grayscale release. FusionInsight RTD also monitors calling latency and TPS of the services.

Figure 2 shows the basic service invoking process in FusionInsight RTD.

Figure 2 Basic service invoking process

1. After the service provider instance is started, it registers its services with the registration center.

   ZooKeeper provides the registration center and manages the list containing the mappings between services and service addresses.

2. The service consumer subscribes to the specific service address list from the registration center when the consumer starts.
3. The registration pushes the changes in the service address list to the clients of related services.
4. The service consumer selects a service address based on service management policies and accesses the service.
