The Four Models
of cloud infrastructure
Accessible by general public and users “pay for what they use” in terms of storage and applications. For many public cloud services, it is free of charge.
Operates solely for the benefit of a single organisation or group of people. Users usually engage a public cloud provider to set up a private cloud.
Shared by several organizations or groups of people with common interests and/or concerns. It is similar to a forum or social networking sites.
Consists of two or more clouds used by individuals and/or organisations.
The above three clouds can all be part of a hybrid cloud.
universal access
anytime, anywhere, any device
Cloud computing manages information in a way that it increases the level of information collaboration between users, mobility of information access and scalability of information use or storage.
cloud advantages
for businesseses & individuals
The cloud provides reliable backup and recovery solutions. In some cases, the cloud itself is used solely as a backup repository of the data located in local computers.
Cloud computing provides enterprises with cost-effective, flexible access to big data’s enormous magnitudes of information.
By leveraging cloud capabilities, companies can save on licensing fees and eliminate overhead charges such as cost of data storage, software updates, and management.
cloud challenges
taking risks
Despite its advantages, the cloud is not perfect. Limited by its universal access nature, it possesses inevitable risks to users and businesses alike. Click on the various icons to find out.
The threat of data compromise increases in the cloud due to the increased number of parties, devices and applications involved.
The risk of data exposure is a challenge for cloud service providers.
System must have the ability to continue operations even in the possibility of a security breach, resulting in a heavy reliance on resource infrastructures and network availability at all times.
Server technical issues such as frequent outages and weak network connection can impair the effectiveness of cloud services.
