Examples described herein are generally related to configurable computing resources.
Software defined infrastructure (SDI) is a technological advancement that enables new ways to operate a shared pool of configurable computing resources deployed for use in a data center or as part of a cloud infrastructure. SDI may allow individual elements of a system of configurable computing resources to be composed with software. These elements may include disaggregate physical elements such as CPUs, memory, network input/output devices or storage devises. The elements may also include composed elements that may include various quantities or combinations of physical elements composed to form logical servers that may then support virtual elements arranged to implement service/workload elements.
The virtual elements of the SDI can be ordered to form a service chain. In general, each virtual element of the service chain will have differing performance limitations. As a result, a virtual element can become a bottleneck in the overall performance of the service chain.
As contemplated in the present disclosure, SDI may allow individual elements of a shared pool of configurable computing resources to be composed with software. Service chains can be formed from an ordered set of these virtual elements. Furthermore, a service chain may be classified as a local service chain. As used herein, a local service chain is a service chain comprising two or more virtual elements (e.g., a virtual machine (VM), container, or the like) executing on one physical platform. In some examples, an orchestrator for the cloud infrastructure may attempt to co-locate the virtual elements of a service chain, for example, to reduce latency, minimize traffic over physical links, or the like. Accordingly, local service chains may be formed.
As the various virtual elements of a service chain have differing performance limitations, bottlenecks can form in the service chain. More particularly, each virtual element of the service chain may operate on a pre-allocated portion of the underlying hardware. As the hardware requirements of each virtual element differ, and can change during operation, a virtual element of the service chain can become a bottleneck. For example, a virtual element can become a bottleneck for throughput, latency, power efficiency, or the like.
According to some examples, techniques to dynamically allocate resources to virtual elements within a service chain (or local service chain) to optimize performance of the service chain and reduce bottlenecks are provided. Performance of the virtual elements of a service chain can be monitored. Resources can be allocated or resource allocations can be modified to increase performance of the service chain based on the monitored performance. For example, a performance monitor can determine where the bottlenecks are within a service chain and allocate more resources to the virtual elements causing the bottleneck to increase overall service chain performance.
It is important to note, that the resource allocation can be done dynamically, during operation of the service chain. As such, resource allocation for the service chain can be modified to account for changes in network traffic or computational demands. Furthermore, it is important to note that a variety of resources can be managed, such as, for example, processing components (CPU, GPU, etc.), memory, cache, accelerators, or the like. Additionally, a number of different performance metrics can be optimized, such as, for example, power usage, throughput, latency, or the like.
According to some examples, as shown in
In some examples, as shown in
According to some examples, as shown in
In some examples, virtualized elements 130 may be arranged to form service chains 140. As shown in
For example, logical server 122-1 (refer to
The SCO 150 can be configured to receive performance information for the service chains (e.g., the service chains 142-a) and to allocate (or adjust an allocation of) a portion of the shared pool of configurable resources (e.g., the disaggregate physical elements 110) for any number of the virtual elements (e.g., the virtualized elements 130) that make up the service chains based on the received information.
Turning more specifically to
Each virtual element of the service chain 142-1 is depicted having a resource allocation 210-a. The resource allocations 210-a correspond to portions of disaggregate physical elements 110 used to implement the logical server 122-1. More particularly, resource allocations 210-a correspond to portions of disaggregate physical elements 110 used to implement each virtual element (e.g., VNFs 136-a, or the like) of the local service chain 142-1.
For example, a resource allocation 210-1 is shown including CPU 112-1, CPU 112-2, Cache 113-1, Memory 114-1, and N/W IO 118-1. The resource allocation 210-1 is further shown supporting the VNF 136-1. Resource allocation 210-2 is shown including CPU 112-3, CPU 112-4, Cache 113-2, Memory 114-2, and N/W IO 118-2. The resource allocation 210-2 is further shown supporting the VNF 136-2. Resource allocation 210-3 is shown including CPU 112-5, CPU 112-6, Cache 113-3, Memory 114-3, and N/W IO 118-3. The resource allocation 210-3 is further shown supporting the VNF 136-3.
Turning more specifically to
The system 200 can further include performance monitors. In particular, the system 200 can include virtual performance monitors (vMonitor) 222-a and physical performance monitors (pMonitor) 224-a. In general, the vMonitors 222-a can be implemented to monitor performance internal to the virtual elements while the pMonitors 224-a can be implemented to monitor performance external to the virtual elements. With some examples, a given vMonitor 222-a can be configured to monitor the queue depth of a buffer, monitor the number of threads waiting to be executed, or the like. For example, the VNF 136-1 is depicted including the vMonitor 222-1. The vMonitor 222-1 can be implemented as part of the VNF 136-1 or may be implemented external to (e.g., as a separate virtual element, or the like) but configured to monitor performance internal to the VNF 136-1. More particularly, if the virtual element is a propriety element (e.g., a proprietary virtual function for intrusion detection, or the like) the vendor of the VNF may include a vMonitor to facilitate reporting of performance as described herein. In some examples, if the virtual element is implemented as a container, the cloud infrastructure may include vMonitors 222-a configured to monitor the internal operation of the container. For example, the VNF 136-3 may be implemented as a container (e.g., one of container 138-a) and the vMonitor 222-2 implemented to monitor various buffers, registers, queues, stacks, or the like internal to the container.
With some examples, the pMonitors 224-a are configured to monitor the performance of the data flow through the service chain (e.g., from input 201 to output 203) and particularly at each point between the virtual elements of the service chain. Furthermore, the pMonitors 224-a can be configured to monitor the performance of disaggregate physical elements 110 supporting the virtual elements. For example, the pMonitors 224-1, 224-2, and 224-3 are configured to monitor corresponding resource allocations 210-a and portions of the data path through the service local service chain 142-1. In some examples, the pMonitors 224-a can be configured to monitor various data processing portions (e.g., vSwitches 134-a, N/W IO 118-a, a shared memory, or the like) of the system 200 to monitor data flow (e.g., throughput, or the like) through the local service chain 142-1 to identify virtual elements that may correspond to a bottleneck in the system. With some examples, pMonitors 224-a can be configured to monitor other portions of the logical server 122-1 or disaggregate physical elements 110 implementing the logical server 122-1. For example, a given pMonitor 224-a can be configured to monitor cache misses, CPU utilization, memory utilization, or the like for a resource allocation 210-a.
The SCO 150 can be configured to receive performance information for the service chain 142-1. In particular, the SCO 150 can be configured to receive performance information from the vMonitors 22-a and the pMonitors 224-a, the performance information to include indications of the performance of the various virtual elements forming the local service chain 142-1. For example, the SCO 150 can receive performance information for the VNF 136-1 from the vMonotor 222-1 and the pMonitor 224-1. Additionally, the SCO 150 can receive performance information for the VNF 136-2 from the pMonitor 224-2. Furthermore, the SCO 150 can receive performance information for the VNF 136-3 from the vMonotor 222-2 and the pMonitor 224-3.
Additionally, the SCO 150 can determine a resource allocation (e.g., resource allocations 210-a) or an adjustment to a resource allocation (refer to
Turning more particularly to
In some examples, the SCO 150 can be configured to determine an adjustment to make to a resource allocation. With some examples, the SCO 150 can determine that processing power needs to be increased or decreased. For example, if the policy specifies that power is to be conserved, and the performance information indicates that the CPUs 112-a are underutilized (e.g., based on the pMonitor 224-a monitoring the C-states of the CPU's 112-a, or the like) in a given VNF 136-a, the SCO 150 can determine that the resource allocation for the given VNF 136-a be adjusted to comprise less computing power (e.g. less CPUs 112-a). For example, the resource allocation 210-5 includes less CPUs 112-a than the resource allocation 210-2 but supports the same VNF 136-a in the system 200.
In some examples, if the policy specifies that network throughput is to be maximized and the performance information indicates that a given VNF 136-a is maximizing (e.g., based on monitoring the vSwitches 134-a, the N/W IO elements 118-a, or the like) its allocated network bandwidth, the SCO 150 can determine that the resource allocation for the given VNF 136-a be adjusted to increase network bandwidth, thereby increasing overall throughput through the service chain. For example, the resource allocation 210-4 includes less more N/W IOs 118-a than the resource allocation 210-1 but supports the same VNF 136-a in the system 200.
It is important to note, that the present disclose can be implemented to optimize performance of a virtual element that is not part of a service chain. Additionally, the present disclosure can be implemented to optimize performance of a service chain or a virtual element supported by a cloud infrastructure implemented across logical servers.

Various components of apparatus 600 and a device, node or logical server implementing apparatus 600 may be communicatively coupled to each other by various types of communications media to coordinate operations. The coordination may involve the uni-directional or bi-directional exchange of information. For instance, the components may communicate information in the form of signals communicated over the communications media. The information can be implemented as signals allocated to various signal lines. In such allocations, each message is a signal. Further embodiments, however, may alternatively employ data messages. Such data messages may be sent across various connections. Example connections include parallel interfaces, serial interfaces, and bus interfaces.
Included herein is a set of logic flows representative of example methodologies for performing novel aspects of the disclosed architecture. While, for purposes of simplicity of explanation, the one or more methodologies shown herein are shown and described as a series of acts, those skilled in the art will understand and appreciate that the methodologies are not limited by the order of acts. Some acts may, in accordance therewith, occur in a different order and/or concurrently with other acts from that shown and described herein. For example, those skilled in the art will understand and appreciate that a methodology could alternatively be represented as a series of interrelated states or events, such as in a state diagram. Moreover, not all acts illustrated in a methodology may be required for a novel implementation.

Furthermore, it is important to note, that the present disclosure may be implemented to adjust resource allocation for a service chain dynamically (e.g., during operation of the system implementing the service chain). Accordingly, logic flow 700 may be repeated (e.g., iteratively, periodically, or the like) to adjust the resource allocation based on repeatedly receiving performance information (e.g., at block 710) and repeatedly adjusting resource allocations (e.g., at block 720). As such, the logic flow 700 can be implemented to optimize performance of a service chain during operation to account for changing conditions (e.g. network data, computational requirements, or the like).
