This patent arises from a continuation of U.S. patent application Ser. No. 15/370,747, (Now U.S. Pat. No. 10,558,449) which was filed on Dec. 6, 2016. U.S. patent application Ser. No. 15/370,747 is hereby incorporated herein by reference in its entirety. Priority to U.S. patent application Ser. No. 15/370,747 is hereby claimed.
The present disclosure relates generally to cloud computing and, more particularly, to methods and apparatus to distribution and execution of instructions in a distributed computing environment.
Virtualizing computer systems provides benefits such as the ability to execute multiple computer systems on a single hardware computer, replicating computer systems, moving computer systems among multiple hardware computers, and so forth.
“Infrastructure-as-a-Service” (also commonly referred to as “IaaS”) generally describes a suite of technologies provided by a service provider as an integrated solution to allow for elastic creation of a virtualized, networked, and pooled computing platform (sometimes referred to as a “cloud computing platform”). Enterprises may use IaaS as a business-internal organizational cloud computing platform (sometimes referred to as a “private cloud”) that gives an application developer access to infrastructure resources, such as virtualized servers, storage, and networking resources. By providing ready access to the hardware resources required to run an application, the cloud computing platform enables developers to build, deploy, and manage the lifecycle of a web application (or any other type of networked application) at a greater scale and at a faster pace than ever before.
