A computer-implemented method for building socket transferring between containers in cloud-native environments by using kernel tracing techniques is provided including probing a connection-relevant system call event by using an eBPF to collect and filter data at a router, creating a mirror call at a host namespace with a dummy server and dummy client by creating the dummy server with mirror listening parameters, sending a server host address mapping to overlay the server host address to the client coordinator in an overlay process, and creating and connecting the dummy client to return a client host address to the server coordinator. The method further includes transferring mirror connections to the overlay process via a forwarder by temporary namespaces entering and injecting socket system calls and probing a transfer call event to map an overlay socket with a transferred dummy socket to activate duplication when the overlay socket is not locked.

Socket transferring for HPC networks using kernel tracing

A computer-implemented method for scheduling and scaling a cloud system for microservice applications is provided including identifying a plurality of nodes within one or more clusters associated with a plurality of containers, generating a model for predicting resource usage among the plurality of nodes, automatically deciding on a number of replicated containers, node bindings, and weight for each replicated container according to application requests and current usage status of a cluster of the one or more clusters that reduce resource usages and microservice cohesion, and determining at least node redistribution of the plurality of nodes within the plurality of containers and workload partitioning to reconfigure scaling, scheduling, and balance deployment requirements of the microservice applications.

Full-dimensional scheduling and scaling for microservice applications

Networking methods and systems include determining a first state of a connection on a first network based on connection buffers at a host. A first system call relating to the connection is identified. A next state of the connection that would result from the first system call is determined. The first system call is executed responsive to a determination that the next state does not move the connection farther from a safe transition state.

Live socket redirection

A computer-implemented method for detecting bottlenecks in microservice cloud systems is provided including identifying a plurality of nodes within one or more clusters associated with a plurality of containers, collecting thread profiles and network connectivity data by periodically dumping stacks of threads and identifying network connectivity status of one or more containers of the plurality of containers, classifying the stacks of threads based on a plurality of thread states, constructing a microservice dependency graph from the network connectivity data, aligning the plurality of nodes to bar graphs to depict an average number of working threads in a corresponding microservice, and generating, on a display, an illustration outlining the plurality of thread states, each of the plurality of thread states having a different representation.

Detecting layered bottlenecks in microservices

A new host is detected being added to a network cluster, wherein each of a plurality of hosts are on the network cluster. Available interfaces on each of the plurality of hosts on the network cluster are detected responsive to detecting the new host being added. A classless inter-domain routing (CIDR) range is calculated for hosts and interfaces on the network cluster using the available interfaces. Pod routes with interface range and L3 host routes are set for each host.
