Securities and threats of cloud computing and solutions

Currently, IT computers are one of the most attractive technologies due to the ability to reduce computational costs by increasing the flexibility and scale of IT processes. In recent years, cloud computing has become a promising concept in one of the fastest parts of the IT industry. Such organizations have expressed concerns about critical issues regarding broad implementation of cloud computing (for example, security). This concern is since the data is stored remotely by the client; In fact, it can be saved everywhere. Security is one of the most accessible problems in cloud computing; Different companies watch cloud computing carefully for security risks. Private security and private threats can be less than cloud computing than those that must be stored in a single machine, instead of in the cloud (a network of computers used for external registration and conservation). To fully assess the profitability of cloud computing, it is necessary to compare the benefits of cloud computing and the risks to the current situation. Thus, customers have problems when they consider cloud computing for their business. In this article, we summarize the issues of reliability, availability and security of cloud computing (RAS issues), and provide feasible and accessible solutions.
