Google is perceived as leader for setup, infrastructure, and application management in public clouds while IBM is viewed as leading in these attributes in private clouds.
"Most developers expect to be in a hybrid situation going forward with respect to application deployment in the cloud," said Janel Garvin, CEO of Evans Data, in a statement released by the company. "And these two vendors are perceived of as best filling the two main requirements for either public or private clouds, i.e., security and reliability. With no other vendors even close in perceived leadership, it's likely that we'll see IBM and Google dominating the cloudscape for the foreseeable future."
Developers, Evans said, want to move applications between public and private clouds.
Public clouds are generally considered to be third-party data centers available for Internet-based application deployment, from companies such as Amazon. Private clouds are usually thought of as internal networks of systems that utilize cloud-based application deployment techniques.
