Provisioning is the allocation of resources and services to a user. Cloud provisioning is based on procedures that specify how a user procures cloud services and resources from a cloud provider. Cloud services include infrastructure as a service, software as a service, and platform as a service. Cloud resources include processing resources, network resources, storage resources, and etcetera.
In current cloud architectures, a service provisioner includes multiple sub provisioners that support different types of activities. Identity and Access Management (IAM) is a framework of policies and technologies that ensure users in an enterprise have appropriate access to technology resources (e.g., an authentication manager for each provision operation). When a provision request reaches the service provisioner, a series of provision operations in the service provisioner occurs. For example, the service provisioner may trigger a provision operation based on the provision request, the service provisioner may trigger an IAM request for authentication, and/or a provision operation is triggered by other operations.
According to one embodiment of the present disclosure, an approach is provided in which a set of provision information is generated from a set of provisioners that are in process of fulfilling a client's provision request. The approach creates a set of provision events based on the set of provision information and, in response to detecting a failure of the provision request, the approach generates a provision chain from the set of provision events. The provision chain links the set of provision events based on correlation rules and identifies at least one isolation point of the failure. The approach informs the client of the at least one isolation point of the failure identified in the provision chain.

Northbridge 115 and Southbridge 135 connect to each other using bus 119. In some embodiments, the bus is a Direct Media Interface (DMI) bus that transfers data at high speeds in each direction between Northbridge 115 and Southbridge 135. In some embodiments, a PCI bus connects the Northbridge and the Southbridge. Southbridge 135, also known as the Input/Output (I/O) Controller Hub (ICH) is a chip that generally implements capabilities that operate at slower speeds than the capabilities provided by the Northbridge. Southbridge 135 typically provides various busses used to connect various components. These busses include, for example, PCI and PCI Express busses, an ISA bus, a System Management Bus (SMBus or SMB), and/or a Low Pin Count (LPC) bus. The LPC bus often connects low-bandwidth devices, such as boot ROM 196 and “legacy” I/O devices (using a “super I/O” chip). The “legacy” I/O devices (198) can include, for example, serial and parallel ports, keyboard, mouse, and/or a floppy disk controller. Other components often included in Southbridge 135 include a Direct Memory Access (DMA) controller, a Programmable Interrupt Controller (PIC), and a storage device controller, which connects Southbridge 135 to nonvolatile storage device 185, such as a hard disk drive, using bus 184.
ExpressCard 155 is a slot that connects hot-pluggable devices to the information handling system. ExpressCard 155 supports both PCI Express and Universal Serial Bus (USB) connectivity as it connects to Southbridge 135 using both the USB and the PCI Express bus. Southbridge 135 includes USB Controller 140 that provides USB connectivity to devices that connect to the USB. These devices include webcam (camera) 150, infrared (IR) receiver 148, keyboard and trackpad 144, and Bluetooth device 146, which provides for wireless personal area networks (PANs). USB Controller 140 also provides USB connectivity to other miscellaneous USB connected devices 142, such as a mouse, removable nonvolatile storage device 145, modems, network cards, Integrated Services Digital Network (ISDN) connectors, fax, printers, USB hubs, and many other types of USB connected devices. While removable nonvolatile storage device 145 is shown as a USB-connected device, removable nonvolatile storage device 145 could be connected using a different interface, such as a Firewire interface, etcetera.
Wireless Local Area Network (LAN) device 175 connects to Southbridge 135 via the PCI or PCI Express bus 172. LAN device 175 typically implements one of the Institute of Electrical and Electronic Engineers (IEEE) 802.11 standards of over-the-air modulation techniques that all use the same protocol to wirelessly communicate between information handling system 100 and another computer system or device. Optical storage device 190 connects to Southbridge 135 using Serial Analog Telephone Adapter (ATA) (SATA) bus 188. Serial ATA adapters and devices communicate over a high-speed serial link. The Serial ATA bus also connects Southbridge 135 to other forms of storage devices, such as hard disk drives. Audio circuitry 160, such as a sound card, connects to Southbridge 135 via bus 158. Audio circuitry 160 also provides functionality associated with audio hardware such as audio line-in and optical digital audio in port 162, optical digital output and headphone jack 164, internal speakers 166, and internal microphone 168. Ethernet controller 170 connects to Southbridge 135 using a bus, such as the PCI or PCI Express bus. Ethernet controller 170 connects information handling system 100 to a computer network, such as a Local Area Network (LAN), the Internet, and other public and private computer networks.
While
As discussed above, when a provision request reaches a service provisioner, a series of provision operations in the service provisioner occurs. A challenge found, however, is that multiple provision requests occur in parallel and relationships between operations in the same provision request are uncertain except for directly triggered associations. As a result, when a provision failure occurs, cloud architectures have difficulty in isolating the root cause of the provision failure.
Client 300 sends instances requests 302 to service provisioner 304 executing in cloud 306. Service provisioner 304 interacts with dependency services 308 to fulfill instances requests 302. Dependency services 308 includes identity access management (IAM) framework 310, which interacts with, in one embodiment, kubernetes provisioner 312, virtual machine provisioner 314, storage provisioner 316, and network provisioner 318. In turn, dependency services 308 generate instances 320 for client 300 to utilize.
During the provision request fulfillment process, information capture module plugins 322 capture information pertaining to the provisioning process and send the information to provision events queue 334 within performance monitor 340. In one embodiment, information capture module plugins 322 capture the provision information from each of provisioners 312 through 318, such as requester id, provisioner name, instance id, timestamp, serving instance id, and status. Information capture module plugins 322 also capture authorization information from IAM framework 310, such as requester id, resource id, timestamp, serving instance id, and status. In turn, information capture module plugins 322 generate event data based on the captured information and send the event data to provision events queue 334 where provision events queue 334 persists all of the provision events accordingly (see
When client 300 detects a provision request failure, client 300 sends fault analysis request 324 to service provisioner 304. In one embodiment, service provisioner 304 detects the provision request failure. Service provisioner 304 then sends fault analysis request 326 to fault analysis module 328 to begin the fault analysis process.
Correlation engine 330 retrieves the provision event information from provision events queue 334 and generates provision chains 332 based pm a set pf correlation rules (see
In one embodiment, provision events queue 334 sends information to optimization engine 336. Optimization engine 336, after running for some time, checks whether removing a parameter for a type of certain correlation will cause error outputs. If no conflict exists, optimization engine 336 removes the parameter in both information capture module plugins 322 and correlation engine 330 to optimize the performance of the event capture and analysis process.
Each of plugins 400-440 captures the required information, forms the captured information into provision event data, and sends the provision event data to provision events queue 334 (see
In one embodiment, plugins 400-440 include two types of plugin implementations. A first type of plugin is an HTTP proxy. The HTTP proxy parses http headers and captures information to generate provision events. A second type of plugin is a library that builds inside a provisioner and IAM framework to provide an interface to generate provision events. This plugin type combines raw data of the provision events into data transform records (e.g., JSON) that are sent to provision events queue 334.
Provision events queue 334 aggregates the event data into two sets of information, which are correlation and aggregation information (columns 520, 530, 540, 550, and 560) and provision properties (columns 570, 580, and 590). The correlation and aggregation information include requester ID column 520, which includes IDs of end users who trigger the provision request. Provisioner name column 530 includes names of provisioners in IAM framework 310 that are also abstracted to be a provisioner. Instance ID column 540 includes IDs of instances that are provisioned by a provisioner. Serving instance ID column 550 includes IDs that trigger provisions to occur. In one embodiment a service instance provision may provision several lower layer service instances as part of components. For example, kubernetes provisioner 312 may need to provision virtual machine (VM) provisioner 314 and storage provisioner 316 as dependencies. Next provisioner column 560 includes names of a next provisioner of the provision request.
The provision properties information includes timestamp column 570 that includes timestamps of when provision events are generated. Status column 580 includes flags that indicate whether the provision starts or completes. Other information column 590 includes other user required information.
Correlation engine 330 includes events selection 600, next events type classification 610, correlation checking 620, and correlation & aggregation 630. In response to receiving fault analysis request 326, events selection 600 selects each of the events from provision events queue 334 related to user entry points (e.g., components that are first accessed). Next events type classification 610 checks the next type of the event in provisioner from the events. Correlation rule checking 620 checks if there are events that fulfill a correlation rule. In one embodiment, the correlation rule default is “Requester id=selected.request id;” “Serving instance id=selected.instance id.”
If a correlation rule is fulfilled, then correlation checking 620 interacts with events selection 600 to select all the events from provision events queue 334. If the correlation rule is not fulfilled, then correlation checking 620 interacts with correlation and aggregation 630 to generate a link between events that fulfill the correlation and aggregate the events that fulfill a criterion, such as “Requester id & same Provisioner & same instance id” (see
Correlation and aggregation 630 generates links between each of the events that fulfill the correlation. Correlation and aggregation 630 aggregates each if the events that fulfill the same ‘Requester id & same Provisioner & same instance id’ into the same node and rewrites their status as: ‘start→completed→failed.’ In turn, correlation and aggregation 630 generates provision chain 332 that identifies isolation points of failure (see
At step 720, the process generates event data based on the captured information and stores the events in provision events queue 334 (see
At step 740, the process (e.g., services provisioner 304) sends fault analysis request 326 to fault analysis module 328. At predefined process 750, the process performs correlation analysis and provision chain generation steps (see
At step 770, in one embodiment, the process uses optimization engine 336 to analyze the provision event data and identify ways in which to minimize future information collected for a certain user, which optimization engine 336 applies to the information capture module plugins. In addition, at step 780, the process updates correlation rules in correlation engine 330 according to the optimization results.
At step 820, the process identifies a next provisioner corresponding to the provision events (column 560 in
The process determines as to whether a correlation rule is fulfilled (decision 840). If a correlation rule is fulfilled, then decision 840 branches to the ‘yes’ branch which loops back to select the events that fulfill the correlation rule and generate links between the previous events and the selected events (step 850). Then, for each of the selected events, the process repeats the step to check the next link (step 820). This looping continues until there are no more events that fulfill a correlation rule, at which point decision 840 branches to the ‘no’ branch exiting the loop.
At step 860, in one embodiment, the process aggregates each of the events that fulfill same “Requester id & same Provisioner & same instance id” combination and rewrites the status as start→completed→failed. At step 870, the process analyzes the correlation and aggregation of each selected event and generates a provision chain accordingly (see
In the embodiment shown in
