Cloud computing is an excellent way for small and mid-size businesses compete in the global economy.
There are essentially three Meadewillis.com cloud service models: infrastructure as a service, platform as a service, and software as a service.
- Infrastructure as a service (IaaS) pertains to the provision of access to server hardware, server storage, network capacity, and/or any other fundamental computing resource
- Platform as a service (PaaS) refers to providing access to basic operating software and services in order to develop and use customer-created software applications
- Software as a service (SaaS) refers to the provision of integrated access to a provider’s overall software application suite
These three cloud service models, then, are deployed through one of four types of settings: private, community, public, and hybrid.
- Private cloud pertains to access from intranet servers with an internal host that is used only by a single organization
- Community cloud pertains to an infrastructure that is accessible only to a specific community
- Public cloud pertains to an infrastructure that is accessible from the whole of the internet, from an external host, that is used by the general public
- Hybrid cloud pertains to a combination of two or more cloud types.
Of course, you would want to use cloud-based computing because it offers a few benefits over other forms of computing (like enterprise). Cloud computing, for one, offers a scalable online environment that makes it easier for smaller companies to handle more and more work volume without a setback to performance.
- Reduced capital costs—organizations are able to provide specialty services in a large-scale computing capacity without sacrificing workload in a fluctuating environment
- Reduced operating costs—as an organization you rent server space from a cloud computing service, which means you only pay for what you use, essentially, instead of paying a staff
- Absolutely no hardware or sofware
- Optimal IT infrastructure that provides you quick access to essential computing services
Of course, everything carries risk; the key is to know if the benefits outweigh these risks. In order to do that, you have to know the risks, first.
- Cloud environments are more often the target of virtual machines and bot malware as well as brute force attacks, than enterprise environments
- Cloud environments are not quite as private and secure as other forms of networked computing.
- When you move all of your information to a cloud service, you place all of the disaster recovery responsibility in their hands (giving you no control over regulation).
