Abstract: An activity stream based alert processor is configured to receive product-specific alerts from respective products implemented in information technology infrastructure, and to process the product-specific alerts to generate one or more activity streams using a specified activity stream format suitable for delivery to one or more remediation elements. For example, the activity streams may be generated in a standardized activity stream format suitable for delivery to one or more social networking applications to facilitate collaborative remediation of the product-specific alerts by multiple administrative entities, such as network, storage and server administrators. The alerts in an illustrative embodiment may comprise system management alerts generated by respective software products or other products in cloud infrastructure of a cloud service provider.
