The future of technology seems pretty bright, considering the development we are getting to see on a global level. Some of the best technologies that we witnessed in the last few years are Artificial Intelligence (AI), Machine Learning (ML), Blockchain, Internet of Things (IoT). Out of the lot, the internet of things (IoT) is growing at an exponential level, and most of the gadgets around us are working on the architecture based on the Internet of Things (IoT). 

Speculations are that the IoT market will reach the mark of 30.9 billion connected devices by the year 2025. Now the intriguing part here is that the number of devices connected to IoT will be approximately three times the human population right now. Most of the top mobile application developers in USA offer IoT apps to businesses for better operations and seamless working. It is known that IoT apps can be built on cloud platforms. The reason behind developing IoT applications on the cloud is that they become more scalable and productive. 

Moving further in the article, we will try to explain the procedure of building scalable IoT applications on the cloud. But before that, we will first learn about the basics of IoT and IoT app development, which is surely going to help you understand the concept better. Moreover, if you are a business that is looking for a company that provides IoT application development services, then here you will understand all that is needed to be looked out for. 

Basic definition of IoT and its working explained

A network of interconnected devices on the internet is known as Internet of Things or IoT. In the current times, things like kitchen appliances, cars, cleaning devices, and even our smartwatches all work on the principles of IoT. The ecosystem of Internet of Things (IoT) consists of things like entity network layers, application layers, remotes, physical layers, networks, analytics, data storage, and dashboard. 

Manufacturing, defense, retail, mining, food services, agriculture, connected homes, smart buildings, logistics, infrastructure, smart cities, banks, oil, transportation, gas and more can be said to be the major industries where the involvement of IoT is increasing with time. First things first, IoT is made up of four individual components, including hardware, software, network, and computing servers. Moving further in this article, we will briefly explain these components and how they contribute to making a scalable IoT ecosystem. 

Components of IoT

Hardware: Any IoT app development services providing company should know that the hardware plays a major role in the optimization of IoT. They should go for reliable third parties that offer chips, sensors, appliances, and more. On the contrary, the hardware can also be created in-house according to the requirement of the businesses. Choosing the best hardware plays a major role in establishing a seamless connection between different components of IoT. 

Cloud: The cloud is something without which the IoT ecosystem will fail and achieve scalability. This is the reason why cloud servers play a major role in IoT application development. The cloud servers are used to manage the storage, flow, and processing of the data that is produced by IoT. Having customized computing power via the cloud servers is something that is necessary at this point in time because the IoT app development company is supposed to keep the data safe from any kind of breach. For the best cloud solutions, you can contact a company that provides cloud computing consulting services.  

Software: IoT software is nothing but end-user applications that can be based on the web, smartphone, or even cross-platform. The main purpose of the software is to allow the user to interact with the system. In most of the cases the IoT software or application works as a dashboard that holds all the stored data and information received via the sensors. It also helps the user in altering the settings and even making minor changes to the connected devices. This software is mainly designed to perform particular tasks, and they need only a small amount of user interface as human interaction is pretty limited. 

Networks: Another significant component that plays a vital role in IoT application development. It helps in linking all the devices in an IoT ecosystem. Connectivity options ranged from MQTT, LAN to HTTP, and LPWAN for stationary devices, satellites, WiFi, wireless cellular, or Bluetooth. All of the connectivity options have their own advantages and disadvantages. 

For example, WiFi offers high speed and decent compatibility, but it only works in short ranges and consumes a lot of power as compared to any other alternative. Similarly, Bluetooth offers high speed and low power consumption, but it also has a short range of operation and low bandwidth. Talking about ethernet, it offers high speed coupled with security. However, it lacks mobility and has a short range of functioning. As for cellular networks, they offer long-range, high-speed, global coverage and reliability. 

Like every other network, the cellular network also has limitations, which are high cost, high power consumption, and security vulnerabilities. The satellites provide a long-range along with nearly global coverage but have disadvantages like low speed, high cost, and even high latency. LP WAN, on the other hand, delivers long-range, fast-paced performance and low power consumption. Nonetheless, it also has limitations like high latency and low bandwidth. 

So, these are the four major components that are used to build an IoT ecosystem by any company that provides IoT application development services. The growth of IoT is directly proportional to the growth of smartphone users all around the globe. The reason behind the same is that smartphones can be used in two different ways – they offer users remote access to multiple services at the same time, and they pack various sensors that can establish a connection with WiFi or Bluetooth flawlessly. 

How to create an IoT application on the cloud?

So, basically, any IoT app development company needs to follow a set of steps to create a scalable IoT application on the cloud. One thing to mention here is that the four components needed for the IoT app development should be taken care of. In terms of hardware, an IoT application development company is supposed to look out for things like hardware size, weight, dimensions, operation environment, sensor type, product design, appearance, connection protocols, certification standards according to the region, and power consumption method. 

Once the hardware is looked after then, it comes to the protocols required for the creation of IoT-based applications. The protocols for the same can be separated into two categories – IoT data protocols that are used for establishing the connection of low-power IoT devices and offer communication with hardware on the user side. These types of protocols are represented by the CoAP, WebSocket, HTTP, and MQTT. On the other hand, there are network protocols that connect the devices across a network like LAN, WiFi, Bluetooth, cellular network, etc. The top mobile application developers in the USA need to keep a tab on factors like the distance of connections, connection speed, and device power consumption rate to make their projects highly optimized.

One of the most important factors in IoT application development is the selection of the cloud platform for the same. Here, we will explain the importance of platform selection for developing an IoT application. 

What is an IoT cloud platform, and why is it important?

IoT (Internet of Things) cloud platform works in order to boost and streamline IoT app development. It offers a generic layer for the application that is being built. Now, going to a company to get cloud computing consulting services or looking for cloud service providers to build a complete IoT system is influenced by various things that are in play. Some of the factors that affect the same are data processing, storage, safety, stream, speed, process, scalability, etc.

If you are going to offer your client IoT app development services without relying on different cloud platforms, then you have to provide elements based on the aspects like tech stack, solution scalability, and security. The tech stack means that the shortlisted language for the development should have the support of the developers’ community and should be the one that is used frequently. Moreover, the IoT app development company should be able to choose between libraries and frameworks. In addition, the system should always have the scope of scalability, as without that, matching up with the latest technological trends is going to be a tough nut to crack. 

Apart from that, security is also a major concern for all the IoT applications out there in the market. To tackle data breaches, all the IoT application development services providing companies should offer data encryption, filters, firewalls, authentication, and authorization of drug reports. Another factor that will impact the security of IoT apps is the use of secure protocols for inter-service communication. On top of that, companies are also supposed to make the decision of whether they are going to store the data on-premises or in the cloud. 

Coming back to the point, if you go for an IoT cloud platform that helps in developing and deploying IoT applications for your clients, then there are a lot of options in the market to choose from. To make it easy for you, here we have mentioned the best cloud platforms that you can go for in order to get the best IoT app development services, along with their pros and cons.
