In the previous platform, the network flow between components did not have direct observability. If there is a problem in the communication between user components, you can only manually check through traditional command line tools, while cilium's Hubble service can Provides a UI interface to display real-time traffic status to users, and exposes these indicators to Prometheus for aggregation and sorting, allowing users to observe and monitor the underlying network status more intuitively.

:::info In the Rainbond cluster, each team corresponds to a Namespace of the underlying Kubernetes. Because the underlying network used before cannot perform network management at the Namespace level, so between different teams under the same Rainbond cluster, so the components Mutual access can be freely performed, and users cannot make any restrictions on this, which also leads to the existence of hidden security risks in the underlying network.Now the Kubernetes cluster provided by cilium for network services can solve this problem very well. Users can formulate network policies for each team and each component according to their own needs, strengthen the underlying network management, and realize the security control of the network layer. . :::

OpenVSCode is an online IDE code editor based on a web interface. It only needs a browser on the PC side to use. It is lighter, efficient and concise. Its basic functions completely inherit the VS Code produced by Microsoft. You can continue to strengthen code editing capabilities by installing extensions.The OpenVSCode launched by the Rainbond open source application store is pre-installed with the gitlab-workflow extension to connect to the private code repository Gitlab, and pre-installed with common language runtime environments (the current version integrates Golang , Node.js , python , java ), which can be found in Terminal Quickly debug business code in the terminal.

Rainbond has the ability to quickly build an integrated development environment, and complete the whole process from the start of the code to the final launch of the business through the docking of the code warehouse webhook mechanism.By incorporating the OpenVSCode cloud IDE, the Rainbond integrated development system can be hosted on the cloud, and developers only need a browser to complete the entire process from editing to online. :::

:::info Rainbond is a product that has been committed to opening up the entire process of enterprise application delivery. An indispensable part of this process is the continuous upgrading and iteration of enterprise applications.The unique ability of Rainbond is to package enterprise application systems including multiple service components, and perform one-click installation, upgrade and rollback operations.The above only solves the versioning problem of the application itself.To fully automate the upgrade iteration process of enterprise applications, it is also necessary to automatically handle the version control of the database table structure (Schema).After continuous exploration, Rainbond first integrated the ability of database schema version management in the cloud native era with the industry-leading Liquibase in the field of source code construction. :::
