1. Introduction Cloud Computing is an increase, use, and delivery model for internet-related services. It takes computing to the pool of resources that are made up of a large number of computers, enabling a variety of applications to acquire the ability of calculation, storage space, and information services as needed [1,2]. Firstly, Cloud Computing allows users to use a variety of terminals at any location to obtain application services and the requested resource is from the cloud rather than the fixed entity. When measuring the marine data, the location and terminal are non-stationary, so the computation and storage of data will not be affected by the application of Cloud Computing [3,4]. Next, Cloud Computing has high scalability and large scale. The scale of the cloud can be extended dynamically and this dynamic extension is transparent to the user and does not affect the user’s business and application [5]. Finally, it also has high reliability. Cloud Computing takes use of multiple copies of fault tolerance, multi-computing node isomorphism, and other measures to guarantee the high reliability of service [6,7]. With the purpose of improving the ability of system to collect data and analyze data, it is significant to combine the Cloud Computing with Internet of Things [8,9]. Internet of Things(IoT) is an important part of the new generation of information technology. It is still based on Internet and the expansion of Internet by thing to thing with the purpose of exchanging information and communicating [10,11]. There are various kinds of sensors(pressure, temperature, speed, etc.) in IoT, allowing us to use the data of each sensors and make the sensors interact each other [12,13]. As the basic model of Cloud Computing and IoT shown in Fig. 1, there are three parts in this model. The various sensors collect data and interact with each other. Then the data will be transmitted to the cloud. Based on Internet server and cloud, the Cloud Computing is used to deal with the larger quantity of data. According to the processed data, they will be used in many applications [14,15]. According to IoT and Cloud Computing in marine field, it is a new technology in IoT, which can be used to process the big data and develop new oceanic technologies [16,17]. It combines the IoT and ocean. To be more specific, IoT can be linked with a large number of information from various sensors [18]. According to the contract agreement, any items connected with the Internet in order to achieve intelligent identification, positioning, tracking, monitoring and management of a network [19].
