Cloud computing offers storage and management of data to IoT firms through advanced cloud platforms. The advancement of Software as a Service (SaaS) – which is one of the services offered by the cloud- offers scalability necessary for the delivery of applications. On the other hand, massive data generated by IoT devices per day gets the storage required. According to Cisco, IoT devices will generate more than 847 zettabytes of data annually by 2021. In most cases, the devices generating this data are often sensors that collect data and send it for processing. Although IoT devices can generate massive amounts of data, only cloud computing enables data to travel. The data allows for better workflow efficiency for developers who can store and access data remotely, therefore implementing their projects without hitches and unnecessary delays.

But the biggest question that many ask is, how does IoT-to-cloud connectivity actually work? Like every communication channel, the link between the IoT device and cloud service is achieved through either wired or wireless communication networks such as Ethernet or Wi-Fi. The communication is facilitated by a common transport and application layer protocol between an IoT device and a cloud service.

The cloud speeds up the storage and analysis of data in real-time, allowing firms to benefit from the aspect of speed. According to a survey by InformationWeek, speed is a critical factor in IoT. 65% of the respondents stated that the ability to meet business demands quickly is an important reason for moving to a cloud environment. Cloud computing means your organization is safe from the extreme cost of extensive hardware, configuration, and management of networks and infrastructure. Furthermore, cloud computing allows businesses to scale up their infrastructure depending on their demands without the need to set up additional hardware or infrastructure. This addresses the aspect of the cost of development.

Security, scalability, and reliability are critical in IoT-to-cloud connectivity. The current cellular technologies are known for their reliability, scalability, and security hence their choice in IoT projects. The 3GPP standard, which Cellular Internet of Things (CIoT) is based on, is useful because it takes advantage of the existing infrastructure to give excellent IoT coverage and offers commendable speeds. The CIoT includes devices, a dedicated SIM card, and a management platform. It provides benefits such as better coverage, security, and a bandwidth of up to 10 Gbps. The coverage of cellular data is broad and continues growing with the potential to reach underground spaces, remote environments, and buildings. On the other hand, the end-to-end security is supported by the SIM card's credentials, which keeps the data secure.

In a nutshell, building IoT solutions will involve solving various challenges across different domains. Regardless of the obstacles, connecting IoT devices to the cloud brings the aspects of speed, scalability, visibility, and affordability, which are necessary for effective operations. Adhering to the connectivity best practices enables enterprises to seamlessly connect the cloud with a secure network and improve their operations through large-scale IoT deployments.
