Secure network access from sandboxed applications

The invention relates to secure network access from sandboxed applications. Methods, systems, and computer programs are presented for enabling any sandboxed user-defined function code to securely access the Internet via a cloud data platform. A cloud data platform receives a remote procedure call from a user defined function (UDF) executing within a sandbox process. The UDF includes code related to at least one operation to be performed. The cloud data platform provides an overlay network to establish a secure egress path for UDF external access. A cloud data platform enables a UDF executing in a sandbox process to initiate a network call. 本申请涉及从沙箱化应用进行安全网络访问。提出了用于使任何沙箱化用户定义函数代码能够经由云数据平台安全地访问互联网的方法、系统和计算机程序。云数据平台从在沙箱进程内执行的用户定义函数(UDF)接收远程过程调用。UDF包括与待执行的至少一个操作相关的代码。云数据平台提供覆盖网络以建立用于UDF外部访问的安全出口路径。云数据平台使在沙箱进程中执行的UDF能够发起网络调用。
