Application link resource scaling method, apparatus, and system based on concurrent stress testing of plural application links

One or more computer readable media storing executable instructions that, when executed by one or more processors, cause the one or more processors to perform acts comprising:

• obtaining an application link, the application link being a path formed by at least two associated applications for a service scenario, the service scenario comprising a plurality of application links;
• determining target resource information required by capacity scaling for at least one subset of the at least two associated applications in the application link;
• allocating respective resources to the at least two associated applications according to the target resource information, wherein the respective resources are initialized for the at least two associated applications based at least in part on a ratio of flow information of the at least two associated applications;
• performing a stress test on the application link, wherein performing the stress test on the application link comprises:
• determining that one of the at least two associated applications in the application link is involved in the plurality of application links;
• ensuring that resources of each of the plurality of application links are sufficient;
• and
• performing the stress test on the plurality of application links at a same time for making resource correction after ensuring that the resources of each of the plurality of application links are sufficient;
• correcting the respective resources allocated to the at least two associated applications according to a result of the stress test, wherein correcting the respective resources allocated to the at least two associated applications comprises taking one of the at least two associated applications offline, and updating application information of a resource associated with the one of the at least two associated applications to be reserved for another of the at least two associated applications without updating application information for all of the at least two associated applications;
• and
• generating instances of the at least two associated applications using the respective resources.
