Abstract

An apparatus for enabling resiliency for cloud computing systems is provided. An apparatus includes a processor and a memory storing computer program code. The memory and the computer program code are configured to, with the processor, cause the apparatus to perform actions. The actions include modifying a topology graph of a network architecture by mapping processes flows onto the topology graph and creating a resiliency graph based on the modified topology graph. The actions also include modifying the resiliency graph by translating at least one SLA into the resiliency graph and identifying overlaps and dependencies in the modified resiliency graph. Apparatus and computer readable instructions are also described.

Claims

1. An apparatus, comprising a processor;

and a memory including computer program code, the memory and the computer program code configured to, with the processor, cause the apparatus to perform at least the following;

to modify a topology graph of a network architecture by mapping processes flows onto the topology graph;

to create a resiliency graph based on the modified topology graph;

to modify the resiliency graph by translating at least one service level agreement into the resiliency graph; and

to identify overlaps and dependencies in the modified resiliency graph.

2. The apparatus of claim 1, where the memory and the computer program code are further configured to cause the apparatus to determine at least one potential point of failure based on the overlaps and dependencies.

3. The apparatus of claim 2, where the memory and the computer program code are further configured to cause the apparatus to classify the potential point of failure.

4. The apparatus of claim 2, where the memory and the computer program code are further configured to cause the apparatus to split the subsystem into a plurality of instances of the subsystem in response to determining that the potential point of failure is a subsystem shared by multiple processes.

5. The apparatus of claim 2, where the memory and the computer program code are further configured to cause the apparatus to ensure the plurality of critical subsystems does not share a hypervisor in response to determining that the potential point of failure is a plurality of critical subsystems shared by multiple processes.

6. The apparatus of claim 2, where the memory and the computer program code are further configured to cause the apparatus to allow the plurality of non-critical subsystem to share infrastructure resources in response to determining that the potential point of failure is a plurality of non-critical subsystem shared by multiple processes.

7. The apparatus of claim 2, where the memory and the computer program code are further configured to cause the apparatus to, determine a primary and backup split for the replicated subsystem in response to determining that the potential point of failure is a replicated subsystem.

8. An article of manufacture tangibly embodying computer readable instructions which, when implemented, cause a computer to carry out the steps of a method comprising:

modifying a topology graph of a network architecture by mapping processes flows onto the topology graph;

creating a resiliency graph based on the modified topology graph;

modifying the resiliency graph by translating at least one service level agreement into the resiliency graph; and

identifying overlaps and dependencies in the modified resiliency graph.

9. The article of manufacture of claim 8, where the steps of the method further comprise, in response to determining that a potential point of failure is a subsystem shared by multiple processes, splitting the subsystem into a plurality of instances of the subsystem.

10. The article of manufacture of claim 8, where the steps of the method further comprise, in response to determining that the potential point of failure is a plurality of non-critical subsystem shared by multiple processes, allowing the plurality of non-critical subsystem to share infrastructure resources.

11. The article of manufacture of claim 8, where the steps of the method further comprise, in response to determining that the potential point of failure is a replicated subsystem, determining a primary and backup split for the replicated subsystem.
