Provisioning of high-availability nodes using rack computing resources
In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a pod manager. The pod manager receives a data object for composing a target composed-node. The pod manager determines that the data object includes an indication for high-availability. The pod manager accordingly composes a collection of composed-nodes based on the data object. The pod manager further configures the collection of composed-nodes to function as the target composed-node.
1. A method of managing composed-nodes of a computing pod, comprising:
receiving a data object for composing a target composed-node and specifying a hardware configuration of the target composed-node;
determining that the data object includes an indication for high-availability;
composing a collection of composed-nodes that includes at least two composed-nodes each being a hardware node in accordance with the hardware configuration specified by the data object, including: for a given node of the collection of composed-nodes, selecting each hardware element of the given node from a pool of hardware elements of a same type available in one or more computing racks in accordance with the hardware configuration; and
subsequent to the composing the collection of composed-nodes, configuring the collection of composed-nodes to function as the target composed-node, including:
provisioning one or more high-availability operation components to each of the at least two composed-nodes, the one or more high-availability operation components operating the at least two composed-nodes to handle tasks directed to the target composed-node, and
provisioning two or more virtual machines (VMs) to each of the at least two composed-nodes.
2. The method of claim 1 , wherein each composed-node of the collection of composed-nodes has a same hardware configuration in accordance with the data object.
3. The method of claim 1 , wherein the target composed-node is requested to provide a service, wherein each composed-node of the collection of composed-nodes has a same software configuration to provide the service.
4. The method of claim 1 , wherein the operating the collection of the composed-nodes includes:
allocating the tasks among the collection of the composed-nodes.
5. The method of claim 1 , wherein the collection of composed-nodes is configured to operate in an active-active mode.
6. The method of claim 1 , wherein the collection of composed-nodes is configured to operate in an active-passive mode.
7. The method of claim 1 , wherein the collection of composed-nodes is composed with hardware elements from different computing racks.
8. An apparatus for managing composed-nodes of a computing pod, comprising:
a memory; and
at least one processor coupled to the memory and configured to:
receive a data object for composing a target composed-node and specifying a hardware configuration of the target composed-node;
determine that the data object includes an indication for high-availability;
compose a collection of composed-nodes that includes at least two composed-nodes each being a hardware node in accordance with the hardware configuration specified by the data object, wherein the at least one processor is further configured to: for a given node of the collection of composed-nodes, select each hardware element of the given node from a pool of hardware elements of a same type available in one or more computing racks in accordance with the hardware configuration; and
subsequent to the composing the collection of composed-nodes, configure the collection of composed-nodes to function as the target composed-node, wherein the at least one processor is further configured to:
provision one or more high-availability operation components to each of the at least two composed-nodes, the one or more high-availability operation components operating the at least two composed-nodes to handle tasks directed to the target composed-node, and
provision two or more virtual machines (VMs) to each of the at least two composed-nodes.
9. The apparatus of claim 8 , wherein each composed-node of the collection of composed-nodes has a same hardware configuration in accordance with the data object.
10. The apparatus of claim 8 , wherein the target composed-node is requested to provide a service, wherein each composed-node of the collection of composed-nodes has a same software configuration to provide the service.
11. The apparatus of claim 8 , wherein to operate the collection of the composed-nodes, the one or more high-availability operation components are configured to:
allocate the tasks among the collection of the composed-nodes.
12. The apparatus of claim 8 , wherein the collection of composed-nodes is configured to operate in an active-active mode or an active-passive mode.
13. A non-transitory computer-readable medium storing computer executable code for managing composed-nodes of a computing pod, comprising code to:
receive a data object for composing a target composed-node and specifying a hardware configuration of the target composed-node;
determine that the data object includes an indication for high-availability;
compose a collection of composed-nodes that includes at least two composed-nodes each being a hardware node in accordance with the hardware configuration specified by the data object, wherein the code is further configured to: for a given node of the collection of composed-nodes, select each hardware element of the given node from a pool of hardware elements of a same type available in one or more computing racks in accordance with the hardware configuration; and
subsequent to the composing the collection of composed-nodes, configure the collection of composed-nodes to function as the target composed-node, wherein the code is further configured to:
provision one or more high-availability operation components to each of the at least two composed-nodes, the one or more high-availability operation components operating the at least two composed-nodes to handle tasks directed to the target composed-node, and
provision two or more virtual machines (VMs) to each of the at least two composed-nodes.
14. The non-transitory computer-readable medium of claim 13 , wherein each composed-node of the collection of composed-nodes has a same hardware configuration in accordance with the data object.
15. The non-transitory computer-readable medium of claim 13 , wherein the target composed-node is requested to provide a service, wherein each composed-node of the collection of composed-nodes has a same software configuration to provide the service.
16. The non-transitory computer-readable medium of claim 13 , wherein to operate the collection of the composed-nodes, the one or more high-availability operation components are configured to:
allocate the tasks among the collection of the composed-nodes.
17. The non-transitory computer-readable medium of claim 13 , wherein the collection of composed-nodes is configured to operate in an active-active mode or an active-passive mode.
