Abstract: Methods and systems for cloud computing service integration with an end-user application are described. The methods receive connection information necessary to connect to a cloud platform, the cloud platform being an architecture hosting the cloud computing services, and request, at runtime by submitting the connection information to the cloud platform, endpoint information of one or more components hosted by the cloud platform. The methods then receive, from the cloud platform, in response to the submitted connection information, endpoint information of the one or more components hosted by the cloud platform. The endpoint information includes at least parameters required to invoke the one or more components. The methods also generate metadata for each component of the one or more components, the metadata of each component comprising endpoint information enabling the end-user application to invoke the respective component of the cloud platform. The systems are configured to implement the described methods.

Abstract: A packet generation method based on a server cluster and a load balancer, where the method includes receiving a client request packet, determining a destination server according to a preset load balancing policy, sending an Address Resolution Protocol (ARP) request packet according to the destination Internet Protocol (IP) address, obtaining an ARP response packet according to the ARP request packet, the initial Media Access Control (MAC) address is different from an actual MAC address of the destination server, and updating the destination IP address according to the initial MAC address to obtain an updated client request packet, where the updated client request packet includes the source IP address and an updated destination IP address. In this way, in a process of transmitting a packet, a source IP address of a client is detected on a network layer without changing a source IP address in a request packet.
