Virtualized network service management and diagnostics

A method, comprising:

• applying, by a device, a plurality of diagnostic tests to a plurality of network environments of a software-defined networking wide area network (SD-WAN), wherein the plurality of diagnostic tests are applied hierarchically according to a prioritization of potential issues relating to the plurality of network environments, wherein:
• the plurality of diagnostic tests includes at least one of:
• a hardware diagnostics evaluation, a network connectivity diagnostics evaluation, or a virtualized network services diagnostics evaluation;
• and
• the prioritization of potential issues relates to at least one of a quantity of affected users or a utilization of computing resources;
• generate an analytics model associated with the SD-WAN deployment based on results associated with applying the plurality of diagnostic tests;
• receiving, by the device and based on the plurality of diagnostic tests, service information relating to a plurality of virtualized network services of the plurality of network environments;
• determining, by the device and based on the service information and the analytics model associated with the SD-WAN deployment, a parameter, deviating from a particular range of values that corresponds to the parameter and is associated with a normal operation of a particular network environment of the plurality of network environments, via an application program interface (API) associated with the particular network environment,
• wherein the parameter relates to an issue associated with the particular network environment,
• determining, by the device and based on the analytics model, a recommendation for resolving the issue;
• and
• implementing, by the device, the recommendation for resolving the issue.

A non-transitory computer-readable medium storing one or more instructions, the one or more instructions comprising:

• one or more instructions that, when executed by one or more processors of a gateway device, cause the one or more processors to:
• receive service information that identifies a state of a plurality of network environments of a software-defined networking wide area network (SD-WAN) deployment based on applying a plurality of diagnostic tests hierarchically according to a prioritization of potential issues relating to the plurality of network environments, wherein:
• the SD-WAN deployment includes a plurality of virtualized network services associated with the plurality of network environments;
• the plurality of diagnostic tests includes at least one of:
• a hardware diagnostics evaluation, a network connectivity diagnostics evaluation, or a virtualized network services diagnostics evaluation;
• and
• the prioritization of potential issues relates to at least one of a quantity of affected users or a utilization of computing resources;
• generate an analytics model associated with the SD-WAN deployment based on results associated with applying the plurality of diagnostic tests;
• detect, based on the service information and the analytics model associated with the SD-WAN deployment, an issue, associated with a particular network environment of the plurality of network environments, via an application program interface (API) associated with the particular network environment;
• generate, based on the analytics model, a recommendation associated with a resolution of the issue;
• and
• provide the recommendation to a client device associated with the particular network environment.
