It’s a highly competitive and dynamic market because players spent a lot of money in research and development to launch new and differentiated products at competitive prices. Due to liberal government regulations, the market easily attracts new players. Amazon web services (AMZN) is the largest public cloud in the market. In May, 2014, Google (GOOG) launched Google compute engine and Rackspace (RAX) relaunched its public cloud services in the market. VMware (VMW) vCloud Hybrid Service and Microsoft (MSFT) Azure services platform are other leading players in the market.

One of the important factors driving public cloud adoption is an organization’s preference and need to reduce overall expenditure on IT infrastructure.

It’s preferred by companies that have few regulatory hurdles to overcome and are looking to outsource their IT requirements either partially or fully. By employing cloud services, they’re as good to launch themselves in the market with immediate online storage and services.
