Cloud computing is sometimes described as a stack of three layers of services that is collectively called the “cloud.” The idea behind cloud computing is that end users can participate in bulk resources which can be accessed efficiently.
A service is considered to be “cloud” when it aligns with these characteristics:
1 Self-service that is accessible on-demand
2 Resources that are connected across multiple customers
3 The ability to scale during peak seasons
4 Access to a broad range of platforms
The three layers within cloud computing from top to bottom are:
1 Software as a Service (SaaS) which are applications delivered online and designed for end-users.
2 Platform as a Service (PaaS) which is a set of tools and services that make deploying applications quick.
3 Infrastructure as a Service (IaaS) which is hardware and software that supports and energizes all the storage, servers, operations, and networks that the cloud stack uses.
An integrated system includes a combination of these services and is ideal for accelerating to a virtualized data center that efficiently deploys a flexible data center infrastructure. Organizations have to keep in mind vendor management when selecting the right cloud computing system and must balance the ability to innovate with outcomes.
If you are looking to move to cloud computing, assess your situation, and consider an integrated approach that will allow for the flexibility, accessibility, and ease of use your company needs.
