Abstract: Techniques are described for dynamically establishing and scaling IPSec tunnels to connect hundreds of sites of a network by making use of the user intent of connecting certain applications for applying security policies and translating it dynamically based on the location and needs of the workloads to set up the network on demand. The techniques involve a tight loop between the network controller of a site (e.g., a cloud Application Policy Infrastructure Controller) and the inter-site or multi-cloud inter-connect controller, stitched through services that enable security and network automation at scale. In particular, to control the number of IPSec tunnels, IPSec tunnels are established only when required. Additionally, IPSec tunnels may be eliminated when no longer required. Thus, resources of a network may be used in a measured way that is necessary and sufficient to meet network traffic demand.

Abstract: Systems, methods, and computer-readable media for replicating data in a distributed storage cluster using an underlying network. In some examples, a primary node of a placement group in a network overlay of a distributed storage cluster can receive data for replication in the placement group. The primary node can provide the data to a first slave node of a plurality of slave nodes within the placement group in an underlying network of the distributed storage cluster. The data can subsequently be replicated using the underlying network by providing the data to at least one other slave node of the plurality of slave nodes within the placement group in the underlying network directly from the first slave node in the underlying network.

Abstract: Aspects of the subject technology relate to ways to determine the optimal storage of data structures in a hierarchy of memory types. In some aspects, a process of the technology can include steps for identifying a retrieval cost associated with retrieving a field in an object from data storage, comparing the retrieval cost for the field to a cost threshold for storing data in persistent memory, and selectively storing the field in either a persistent memory device or a non-persistent memory device based on a comparison of the retrieval cost for the field to the cost threshold. Systems and machine-readable media are also provided.

Abstract: Aspects of the disclosed technology relate to ways to determine the optimal storage of data structures across different memory device is associated with physically disparate network nodes. In some aspects, a process of the technology can include steps for receiving a first retrieval request for a first object, searching a local PMEM device for the first object based on the first retrieval request, in response to a failure to find the first object on the local PMEM device, transmitting a second retrieval request to a remote node, wherein the second retrieval request is configured to cause the remote node to retrieve the first object from a remote PMEM device. Systems and machine-readable media are also provided.
