Distribution and execution of instructions in a distributed computing environment
摘要
說(shuō)明書
The example instruction validator 650 determines whether the retrieved instructions are valid (block 840). The example instruction validator 650 may determine whether the retrieved instructions are valid by, for example, computing a checksum of the retrieved instructions stored in the instruction cache 620 and comparing the computed checksum against the checksum provided by the repository 134. However, any other approach to validating retrieved instructions may additionally or alternatively be used. For example, validating the instructions may involve verifying that any pre-requisites of the instructions have already been installed and/or are otherwise available for execution of the instructions, performing a virus scan on the instructions, etc.
If the example instruction validator 650 determines that the retrieved instructions are valid (e.g., block 840 returns a result of YES), the example management endpoint interface 630 provides a status update to the management endpoint 340 indicating that the management agent 350 is processing the instruction (block 845). The example instruction executor interface 660 instructs the instruction executor 610 to execute the instructions stored in the instruction cache 620 (block 850). The example instruction executor 610 then executes the instructions. When executing the instructions, the example instruction executor 610 may output results of the execution of the instructions via, for example, a standard out interface, a standard error interface, an event log, an output file, etc.
