Diagonal autoscaling of serverless computing processes for reduced downtime

1. A method comprising:

receiving a request to execute a computing process in a serverless computing environment;

creating a first node within the serverless computing environment to execute the computing process, wherein a first amount of computing resources are assigned to implement the first node;

determining that computing resources necessary to implement the first node exceeds the first amount of computing resources;

determining, with a vertical autoscaling (VA) process which executes on a first computing unit, a second amount of computing resources to include in an updated request;

intercepting, at a second computing unit, the updated request and providing the updated request including the second amount to a horizontal autoscaling (HA) process which executes on the second computing unit;

creating, using the HA process, a second node within the serverless computing environment to execute the computing process, wherein the second amount of computing resources are assigned to implement the second node; and

executing the computing process within the serverless computing environment using both the first and second nodes.

2. The method of claim 1 , wherein the first amount of computing resources remains assigned to the first node after the second node is created.

3. The method of claim 1 , wherein the second amount of computing resources is initially determined by the VA process as an increase in computing resources for the first node.

4. The method of claim 3 , wherein the second amount of computing resources is determined as a proportion of the first amount of computing resources.

5. The method of claim 3 , wherein the second amount of computing resources is determined based on at least one of processing utilization by the first node, memory utilization by the first node, and a total request load for the first node.

6. The method of claim 1 , wherein the request identifies minimum and maximum computing resources for the computing process.

7. The method of claim 6 , wherein the computing resources include memory capacity available to the computing process and processing capacity available to the computing process.

10. The method of claim 9 , further comprising proportionally routing requests for the computing process to be fulfilled by the first and second nodes based on relative magnitudes of the first and second weights, and wherein the weights are normalized such that the smallest weight has a value of 1.

11. The method of claim 9 , further comprising:

detecting that a number of requests for the computing process has decreased by more than a predetermined threshold; and

halting at least one of the first and second nodes.

12. The method of claim 11 , wherein the at least one of the first and second nodes is selected based on the first weight and the second weight.

13. A system comprising:

determine that computing resources necessary to implement the first node exceeds the first amount of computing resources;

determine, with a vertical autoscaling (VA) process which executes on a first computing unit, a second amount of computing resources to include in an updated request;

intercept, at a second computing unit, the updated request and providing the updated request including the second amount to a horizontal autoscaling (HA) process which executes on the second computing unit;

create, using the HA process, a second node within the serverless computing environment to execute the computing process, wherein the second amount of computing resources are assigned to implement the second node; and

execute the computing process within the serverless computing environment using both the first and second nodes.

14. The system of claim 13 , wherein the first amount of computing resources remains assigned to the first node after the second node is created.

15. The system of claim 13 , wherein the second amount of computing resources is initially determined by the VA process as an increase in computing resources for the first node.

16. The system of claim 15 , wherein the second amount of computing resources is determined as a proportion of the first amount of computing resources.

17. The system of claim 13 , wherein the instructions further cause the processor to update a routing table with a first weight for the first node and a second weight for the second node, wherein the first weight is determined based on the first amount of computing resources and the second weight is determined based on the second amount of computing resources.

18. The system of claim 17 , wherein the instructions further cause the processor to proportionally route requests for the computing process to be fulfilled by the first and second nodes based on relative magnitudes of the first and second weights.

19. The system of claim 17 , wherein the instructions further cause the processor to:

detect that a number of requests for the computing process has decreased by more than a predetermined threshold; and

halt at least one of the first and second nodes.

20. A non-transitory, computer-readable medium storing instructions which, when executed by a processor, cause the processor to:

receive a request to execute a computing process in a serverless computing environment;

create a first node within the serverless computing environment to execute the computing process, wherein a first amount of computing resources are assigned to implement the first node;

determine that computing resources necessary to implement the first node exceeds the first amount of computing resources;
