Abstract: A cloud infrastructure performs governance and security control for datacenters on a cloud platform. The system specifies one or more session policies for the plurality of datacenters. A session policy associated with a datacenter specifies a set of access conditions for accessing the entities of the datacenter, and may be generated based at least on the network information in the declarative specification for the datacenter, and network artifacts from provisioning the network resources for the datacenter. Responsive to receiving a request to access an entity of a datacenter from a user, the system obtains credentials for the user and attaches the session policies. Responsive to determining that the credentials are used to access the datacenter from a set of access conditions that match the set of access conditions in the attached session policy, the cloud platform grants access.

Abstract: Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for managing blockchain-based trustable transaction services. One of the methods includes: storing order data of an order between a buyer and a seller on a blockchain of a blockchain network, the order data including one or more payment conditions and data of a trustable undertaking (TU) service for the order, verifying that the buyer has the TU service for the order guaranteed by the buyer financial institution, generating a smart contract for the order based on the order data on the blockchain, and executing the smart contract to automatically instruct the buyer financial institution to make a payment of the order for the buyer to the seller according to the TU service for the order in response to determining that a payment condition for the payment specified in the smart contract is met.

Abstract: Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for managing blockchain-based trustable transaction services. One of the methods includes: storing order data of an order between a buyer and a seller on a blockchain of a blockchain network, the order data including one or more payment conditions and data of a trustable undertaking (TU) service, generating a trustable undertaking certificate for the order based on the order data, storing the trustable undertaking certificate on the blockchain, and transmitting the trustable undertaking certificate to a seller financial institution to determine whether to approve a financing request of the seller based on the trustable undertaking certificate. The TU service is guaranteed by a buyer financial institution that automatically makes a payment based on a credit of the buyer in response to that a condition specified in a smart contract deployed on the blockchain is met.
