Scheduling upgrades in distributed computing systems

At least one non-transitory computer-readable storage medium including instructions that when executed by a first computing node, cause the first computing node to:

• detect a current version of a first component of the first computing node of a clustered computing system and a current version of a second component of a second computing node of the clustered computer system;
• based on detecting the current version of the first component and the current version of the second component, obtain an upgrade module corresponding to the first component and an upgrade module corresponding to the second component;
• generate a time-based sequence of instructions for installation of the upgrade module corresponding to the first component and the upgrade module corresponding to the second component, including instructions for parallel installation on the first computing node and the second computing node, wherein the time-based sequence of instructions comprise one or more sequential upgrade operations for installation of the upgrade module corresponding to the first component and the upgrade module corresponding to the second component;
• and
• install, in parallel, the upgrade module corresponding to the first component on the first computing node and the upgrade module corresponding to the second component on second computing node.

A clustered computing system comprising:

• a storage pool;
• and
• a first cluster comprising a first computing node and a second cluster comprising a second computing node, the first computing node and the second computing node each configured to access the storage pool, wherein the first computing node is configured to:
• detect a current version of a first component of the first computing node hosted on the clustered computing system and a current version of a second component of the second computing node hosted on the clustered computing system;
• based on detecting the current version of the first component and the current version of the second component, obtain an upgrade module for first component and an upgrade module for the second component;
• install, in parallel, the upgrade module for the first component on the first computing node and the upgrade module for the second component on second computing node based at least in part on a time-based sequence of instructions, wherein the time-based sequence of instructions comprises one or more sequential upgrade operations for installation of the upgrade module for the first component and the upgrade module for the second component.
