The benefits of flexibility, scalability, cost savings, etc. are weighed against availability concerns. It is important to evaluate if cloud is right for you from a strategic and operational perspective. Does your demand for IT vary throughout the year? Are the costs of your IT impacting your ability to grow as a business? If so you may consider a cloud option that can be easily scaled.
Physical resources reside in secure facilities, with independent auditing practices followed by the cloud vendors. Data are encrypted and host companies do not have access to those encryption keys. You (the account holder) manage access through user identities and access policies.
In regards to hosted applications, the system will look and work virtually identical to the on-premise counterparts. The difference is that the software is installed and maintained at the vendors facility as opposed to being installed at the clients location
Because data is stored in the cloud, it is not dependent on one device, says Gabe Authier, product manager cloud computing with Viewpoint Construction Software. You can literally grab a new device, get Internet access and never miss a beat. All your data is there, and youll never have to worry about data transfer again, he says.
Many cloud-based hosting services provide redundancy, data backup and data recovery services, says Dexter + Chaney. Data backup is another function of security measures as well, and ideally should be backed up in multiple physical locations.
Cost depends on use.
We start with the Three Thousand rule of thumb: A modest machine with one CPU will cost you three cents per hour. Storing one Gigabyte of data for one month costs Three Thousand. We partner with many Cloud hosting companies to provide deep-dive consulting and a set of tutorials to help you get very accurate cost estimates.
Technically, you can put any application in the cloud.
More importantly, regulatory and compliance concerns prevent enterprises from putting certain applications in the cloud, particularly those involving sensitive customer data.
