Abstract

Disclosed are various embodiments for a deployment management system. A second version of a deployable application is executed concurrently with a first version. Network traffic sent to the first version of the application is redirected to the second version. In the event of an error, network traffic is directed back to the first version of the application. After a period of concurrent execution, the first version of the application is terminated.

Claims

1. A non-transitory computer-readable medium embodying a program executable in at least one computing device, comprising:

code that facilitates an execution of a first version of an application associated with a first amount of computational resources;

code that obtains a second version of the application from a client device over a network;

code that allocates a second amount of computational resources associated with an execution of the second version of the application;

code that facilitates the execution of the second version of the application concurrent to the execution of the first version of the application;

code that reconfigures a load balancer to redirect a portion of network traffic directed to the first version of the application to the second version of the application;

code that, in response to a number of errors in the execution of the second version of the application exceeding a predefined error count threshold, reconfigures the load balancer to direct the portion of network traffic to the first version of the application;

code that, in response to the number of errors exceeding the predefined error count threshold, terminates the execution of the second version of the application; and

code that, in response to the number of errors exceeding the predefined error count threshold, frees the second amount of computational resources after terminating the execution of the second version of the application.

2. The non-transitory computer-readable medium of claim 1, wherein the program further comprises code that, in response to an input from the client device, reconfigures the load balancer to direct the portion of network traffic to the first version of the application.

3. The non-transitory computer-readable medium of claim 1, wherein the program further comprises code that calculates a fee associated with the second version of the application based at least in part on with the second amount of computational resources and the execution of the second version of the application.

4. A system, comprising:

at least one computing device; and

a deployment management application executable in the at least one computing device, the deployment management application comprising;

logic that, contemporaneous to an execution of a first version of an application, allocates resources of the system for an execution of a second version of the application;

logic that, contemporaneous to the execution of the first version of the application, initiates the execution of the second version of the application;

logic that, contemporaneous to the execution of the first version of the application and the second version of the application, reconfigures the system to direct communications sent to the first version of the application to the second version of the application; and

logic that, in response to an number of errors associated with the execution of the second version of the application exceeding a predefined error count threshold, reconfigures the system to direct communications sent to the second version of the application to the first version of the application.

5. The system of claim 4, the deployment management application further comprising logic that frees an allocation of resources of the system associated with the execution of the first version of the application after terminating the execution of the first version of the application.

6. The system of claim 4 further comprising a load balancer, and the logic that reconfigures the system to direct communications sent to the first version of the application to the second version of the application further comprises logic that reconfigures the load balancer to instantaneously redirect the communications.

7. The system of claim 4, wherein the logic that reconfigures the system to direct communications sent to the first version of the application to the second version of the application further comprises modifying a domain name system entry associated with the at least one computing device.

8. The system of claim 4, wherein the deployment management application further comprises logic that terminates the execution of the first version of the application in response to an input from a client device over a network.

9. The system of claim 4, wherein the deployment management application further comprises logic that terminates the execution of the first version of the application in response to a satisfaction of a predefined condition.

10. The system of claim 9, wherein the predefined condition comprises a duration associated with the execution of the second version of the application exceeding a threshold.

11. The system of claim 4, the deployment management application further comprising logic that calculates a fee associated with the execution of the second version of the application.

12. The system of claim 4, further comprising logic that obtains the second version of the application in response to a commitment to a version control system.

13. The system of claim 4, further comprising logic that communicates a notification to a client device indicating a status of a deployment process associated with the second version of the application.

14. A method, comprising:

executing, in at least one computing device, a first version of an application;

obtaining, in the at least one computing device, a second version of the application from a client device;

allocating, in the at least one computing device, an amount of computing resources to facilitate an execution of the second version of the application;

executing, in the at least one computing device, the second version of the application;

redirecting, by the at least one computing device, before terminating an execution of the first version of the application, a portion of network traffic directed to the first version of the application to the second version of the application; and

redirecting, by the at least one computing device, network traffic directed to the second version of the application to the first version of the application in response to a number of errors associated with executing the second version of the application exceeding a predefined threshold.

15. The method of claim 14, further comprising deallocating, by the at least one computing device, the amount of computing resources in response to the number of errors exceeding the predefined error count threshold.

16. The method of claim 14, wherein the specified duration is defined in a user preference input through the client device.

17. The method of claim 14, further comprising deallocating, by the at least one computing device, computing resources associated with the execution of the first version of the application after terminating the execution of the first version of the application.

18. The method of claim 14, further comprising redirecting, by the at least one computing device, network traffic directed to the second version of the application to the first version of the application in response to an input from the client device.

19. The method of claim 14, wherein redirecting the portion of network traffic directed to the first version of the application to the second version of the application comprises reconfiguring a load balancer.

20. The method of claim 14, wherein redirecting the portion of network traffic directed to the first version of the application to the second version of the application further comprises incrementally increasing an amount of redirected traffic.

21. The method of claim 14, wherein the logic that reconfigures the system to direct communications sent to the first version of the application to the second version of the application comprises logic that incrementally increases an amount of the communications sent to the first version of the application being directed to the second version of the application.

22. The method of claim 14, wherein redirecting the portion of network traffic comprises modifying a DNS entry associated with the first version of the application.
