The term cloud computing describes access on demand, via the internet or other network, to IT resources, including servers, applications (physical and virtual), development tools as well as networking capabilities, data storage and much more. They are hosted at a remote data center run by a cloud service provider. Users are able to connect to this infrastructure using a secure connection. Cloud services are accessible through a subscription or charging per usage.
Cloud-based systems enable companies to reduce their costs and time on maintaining IT infrastructure. They also free up IT personnel to focus on other important tasks. The exact savings a business experiences will depend on the particular systems it chooses to move to the cloud and the type of system they’re replacing. However, a recent survey found that IT and Business professionals reported saving between 30 and 50 percent moving to the cloud.
There are many cloud service models, such as Software as a Service(SaaS), Platform as a Serviceand Infrastructure as a Service. SaaS is most likely the most well-known model and is one that many companies are using. It provides the application layer–software such as CRM email, office software- through the internet, eliminating the necessity to upgrade or maintain hardware.
Businesses also gain from the ease of scaling up or down the size of their servers as well as disk storage, paying only what they use. This rapid elasticity is crucial for efficient work processes and to speedily bring new technologies into production. It also means that IT departments don’t need to worry about buying or maintaining expensive hardware and can rely on their cloud vendors to stay current on the latest technological advances.
