1. An application provisioning system for requesting configuration updates for a plurality of application specific infrastructure components across data centers by generating an application provisioning request, said application provisioning system comprising: a memory unit that stores a database and a set of modules; and a processor configured to: create an application provisioning template to receive one or more first inputs from a user for updating or creating configuration of an application specific infrastructure component, wherein said application provisioning template is created by generating one or more customized form fields to receive said one or more first inputs associated with said application specific infrastructure component for updating or creating configuration of said application specific infrastructure component, wherein said application specific infrastructure component comprises at least one of a firewall device, an application delivery controller (ADC) device, a certificate or a domain name system (DNS); automatically generating and executing a first script to fetch a first information associated with said application specific infrastructure component based on said one or more first inputs, wherein said first information comprises at least one of a data center of said application specific infrastructure component or a device type of said application specific infrastructure component; and automatically generating and executing a second script to associate said fetched first information associated with said application specific infrastructure component with said corresponding one or more form fields in said application provisioning template; automatically generate said application provisioning request for updating or creating configuration of said application specific infrastructure component based on said one or more first inputs and said first information associated with said application specific infrastructure component when said user submits said application provisioning template; automatically generate and execute a third script for generating and implementing a work order for said application provisioning request, wherein said generation of said work order comprises automatically compiling a logic to generate appropriate configuration commands using at least one of command line interface (CLI), or Application Program Interface (API) calls based on said one or more first inputs; and automatically implementing said work order for updating or creating said configuration of said application specific infrastructure component, wherein said implementation of said work order comprises automatic modification or updation or creation of said configuration of said application specific infrastructure component based on said application provisioning request raised in said work order and said appropriate configurations commands, wherein said processor is configured provide a plurality of work orders spawned for said application provisioning request; review said configurations of said application specific infrastructure component; modify said configurations of said application specific infrastructure component; submit said work order for approval; implement said work order; search a work order from said plurality of work orders using a plurality of keywords; clone a work order to obtain a cloned work order when said work order that is implemented is rejected; and modify or update said cloned work order and submit said updated cloned work order for approval.
