It brings about ubiquitous and flexible access, on-demand computing resource configuration and vast computation resources at a very low price.
Cloud computing may enable geospatial processing since it refers to, among other things, efficient computing resources providing on demand processing services.
Cloud computing is a pattern for delivering ubiquitous and on demand computing resources based on pay-as-you-use financial model.
Cloud computing has emerged as a paradigm to deliver, on demand computing resources to cloud consumers, similar to other utilities (e.g., water, electricity and gas) [1].
Back in the 1990s, when Internet connectivity boomed and they first became widely used [12], key sizes of 384 through 1024 bits were deemed enough; using longer keys demanded computing resources beyond what was practical at the time.
As stated in [10], most interactive services such as web search, social networks, online gaming, and financial services now are heavily dependent on computations at data centers because their demands for computing resources are both huge and dynamic.
IPs build the capacity to cope with increasing demands for computing resources, which requires significant investment in infrastructure, skilled personnel and incurs power costs.
Compared to ultra-fast sequence alignments and database searches using, for example, BLAST [ 18], protein threading and metathreading that include structure-based components put significantly higher demands for computing resources, which becomes an issue particularly in large, proteome-scale projects.
The foundation of Cloud Computing is sharing computing resources dynamically allocated and released per demand with minimal management effort.
Doing it efficiently requires a system that can dynamically allocate more or less computing resources to programs in response to demand, as well as security that effectively handles maliciously or foolishly programed code.
to function as a flexible, pervasive, and inexpensive accessible pool of computing resources that can be used on demand by any task.
