Methods, systems, and computer program products for executing trusted software components in public computing clouds. Verifiably authentic software components are installed into a tenant partition of a multi-tenant public cloud-based environment. To do so, a software component installer is configured to install registered software components into the tenant partition. Installer processing includes (1) obtaining a component-specific token for a software component wherein the component-specific token is specific to both the software component to be installed and a particular tenant, and (2) installing the software component on behalf of the given tenant in the multi-tenant public cloud-based environment. Prior to executing the underlying code of the tenant-specific software component, the software component is authenticated with a component registry using the component-specific token. Additional trusted components are installed based on demand from within the tenant partition. No user or administrator intervention is needed and no credentials are hard-coded into the software components.

Extending a security perimeter into a tenant-specific public cloud partition

Methods, systems, and computer program products for flexible virtualization system deployment into different cloud computing environments. A set of floating licenses to virtualization system software components is established. The set of floating licenses are configured to permit usage of the virtualization system software components on different cloud computing infrastructures. Workload parameters of a workload to be deployed to one of the different cloud computing infrastructures is considered with respect to cloud attributes corresponding to the different cloud computing infrastructures. One or more candidate target cloud computing infrastructures are selected based upon a comparison between workload attributes of a computing workload and cloud attributes of the candidate target cloud computing infrastructures. Virtualization system software components are deployed into the selected target cloud computing infrastructures. Licenses to the virtualization system software components can float between any combination of different cloud computing infrastructures, including floating the licenses between private clouds and public clouds.

Multi-cloud licensed software deployment

Methods, systems and computer program products for deploying a virtualization system onto cloud computing infrastructure. Virtual machines of a virtualization system are deployed onto computing nodes that are interconnected via a cloud provider's networking infrastructure. When migrating a virtual machine from a source computing node to a target computing node that is also interconnected to the cloud provider's networking infrastructure, the addressing of the to-be-migrated virtual machine changes. Dynamically-updated media access control translation tables are maintained at the computing nodes. The media access control translation tables are populated with cloud provider media access control addresses received from the cloud provider. A virtual switch at each computing node modifies incoming and outgoing packets of a to-be-migrated virtual machine based on contents of that node's media access control translation table. On an ongoing basis, addressing information for migrated virtual machines is received at the computing nodes by operation of address resolution protocols.

Virtual machine migration in cloud infrastructure networks

Methods, systems and computer program products for hibernating a computing cluster. An information lifecycle manager facility (ILM) is invoked to carry out movement of data from the hypervisor of a node of a computing cluster to a different storage location. Multiple nodes of the computing cluster can be hibernated until the entire computing cluster has been hibernated. The ILM observes a replication factor of the computing cluster to suppress saving multiple copies of data. A hibernation object comprising state information of a node is stored in a network-accessible storage location. The hibernation object is accessed in response to an instruction to initiate restoration of all or parts of the computing cluster. The hibernation object can be stored using first cloud computing storage infrastructure and later, can be restored to a different cloud computing infrastructure. Upon restoration, the hibernated cluster has the same state as of the time of hibernation.

Hibernating and resuming nodes of a computing cluster

Disclosed is an improved approach for managing floating/virtual IP addresses in a virtualization system. Where a bare metal cloud provider does not provide adequate facilities to implement broadcast operations, the approach would capture broadcast packets, and from the captured packets, generate calls to the cloud provider to implement configuration changes to reflect the changes desired by the broadcast packets.

Virtual IP support for bare metal cloud infrastructures

Methods, systems and non-transitory computer readable media for handling IP network addresses in a virtualization system. Embodiments are configured to receive, from a cloud provider, a cloud provider media access control address to assign to a network interface of a computing node. Also received from the cloud provider is a cloud provider's IP address associated with the cloud provider's media access control address. A virtual machine on the computing node is configured such that the cloud provider's IP address serves as an IP address of the virtual machine and such that a virtualization system media access control address serves as a MAC address of the virtual machine. The virtualization system correlates the cloud provider's media access control address to the IP address of the virtual machine. In some cases, the cloud provider's media access control address stored in a virtual switch of a hypervisor.

Systems, methods, and media for efficient file replication are provided herein. According to some embodiments, exemplary methods may include detecting a write operation occurring within an operating system of the computing system, identifying block parameters for the write operation, as well as one or more of buffering and batching the write operation, and transmitting the write operation to a replication receiver system.

Efficient file replication

Efficient cloud storage systems, methods, and media are provided herein. Exemplary methods may include locating a Merkle tree of a stored object on a deduplicating block store, comparing an object at a source location to the Merkle tree of the stored object, determining changed blocks for the object at a source location, and transmitting a message across a network to the deduplicating block store, the message including the change blocks and Merkle nodes that correspond to the change blocks.
