A SYSTEM AND METHOD TO DOWNLOAD AND CONVERT A VIRTUAL APPLIANCE IN A CLOUD COMPUTING SYSTEM

FIELD OF THE INVENTION

The present invention relates to a system and method to download and convert a virtual appliance in a cloud computing system. More particularly, the present invention relates to downloading and converting the virtual appliance concurrently by the virtual appliance manager.

BACKGROUND OF THE INVENTION

A virtual appliance is a virtual machine image file consisting of a preconfigured operating system environment and ready-to-run applications. Most of the file format of virtual appliance depends on type of hypervisor. Furthermore, the virtual appliances are available at different marketplaces with different image formats. Conventionally, downloading a virtual appliance is time consuming due to the virtual appliance’s size and network connectivity. Besides, converting from one format of virtual appliance to another format is time consuming as well as it depends on the size of the virtual appliance.

There have been a number of solutions provided for efficient system and method for downloading and converting a virtual appliance and few of them are discussed below.

US 9104517 B2 discloses a system for downloading and executing a virtual application. The system comprises a virtual process manager and a client application wherein both executing on a first computing device in communication with a second computing device over a network. The second computing device storing a virtualized application file at least partially implementing a virtual application. Further, the prior art focuses on downloading the virtual appliances only.

US 9910694 B2 discloses a system and a method for providing a custom virtual appliance. The system comprises one or more processors for generating a description file of a custom virtual appliance based on a user requirement. The processors acquire configuration metadata of the custom virtual appliance from the description file, create a list of candidate virtual appliances based on the configuration metadata, acquire a disk size of the custom virtual appliance based on configuration metadata, acquire a disk size of the specific virtual appliance and determine based on the disk size conversion information, whether the specific virtual appliance is required to convert a disk size of the custom virtual appliance. In response to determining that a candidate virtual appliance from the list is required to convert the virtual disk, the processors construct the candidate virtual appliance as the custom virtual appliance. Further, the prior art focuses on downloading and converting the virtual appliances yet not concurrently.

The aforesaid documents and other similar solutions may strive to provide an effective system and method to download and convert a virtual appliance in a cloud computing system; however, they still have a number of limitations and shortcomings such as, but not limited to, it is time consuming for downloading the virtual appliance as it is depending on the virtual appliance’s size and network connectivity. Furthermore, it is also time consuming for converting from one format of virtual appliance to another format as it is depending on the size of the virtual appliance.
