Industrial IoT vs SCADA: Which is More Powerful?

Industrial IoT and the attached factory notions are fiery hot topics. Most often, there is turbulence among professionals in both on and offline discussions around the performance of Industrial Internet of Things (IIoT) applications. Internet of Things should be scrutinized as a technology that is achieving on top of SCADA. Industrial IoT makes things like adaptable, data analytics, normalization, and internetworking realities. SCADA or Supervisory Control and Data Acquisition is a system of software and hardware that allows industries to control industrial processes locally or at remote locations, monitoring, gathering, and processing real-time data. SCADA is very similar to IoT.

So far, the Internet of Things, the glittery new technology, is establishing swiftly than anything we have seen in modern years. Nonetheless, SCADA is still an important notion in the oil and gas industry. Industrial IoT offers heavy assets in industries like the ease of installation, decreased cost, upsurged data accuracy, and universal remote control and supervising. However, Industrial IoT is comparatively a new modern technology than SCADA.

What are the Differences Between SCADA and Industrial IoT?

SCADA vs. Industrial IoT is an age-old debate topic, but it is most often occurring between industry analysts, IoT vendors, and desk jockeys. Our motto in this blog is to administer an engineer’s viewpoint on the necessary differences between SCADA and Industrial IoT.

1.    SCADA is built for real-time, Industrial IoT is built for analysis

As we already know, SCADA has core features like- concurrent HMIs, agitating, control alliance. Modern engineers require bigger, trustable, efficient datasets to analyze in total so they can distinguish greater optimization trends that aim to the most eloquent ROI. SCADA was never built to serve this function since cloud-based computing embarked to propagate across crucial industries. Industrial IoT was built with features like modern secluded surveillance systems that caught eyes which made work easier and data accessible.

2.   SCADA is for field operations, Industrial IoT works for every employee

 As already mentioned above, the real intent for a SCADA system in heavy industries was to deliver a selected bunch of site and field operations personnel with direct overlook for operational equipment. SCADA was never built to assist Engineers, Accountants, Vendors, or Executives. Most Industrial IoT-based remote supervising platforms allow a collection of integration tools that utilize modern protocols, such as REST or MQTT, that impart data siloes and get data precisely to the point of need.

3.    SCADA requires capital, Industrial IoT can be affordable

Remarkably medium-to-large industrial companies have a private team committed to operating their SCADA system. SCADA construction usually works as a part to facilitate the engineering phase, and paying out often gets swallowed into an authorization for expenditure (AFE), exploiting capital budgets to set up the various SCADA components. The modern Industrial IoT-based remote supervising systems often take a different converge. In few systems, software access might be transported under a “Software-as-a-Service” (SaaS) model, where consumers pay a monthly fee on a per user basis. In this case, the hardware still requires CAPEX funds, but at least some of the capital encumbrance is mitigated by the SaaS model.


Since, with all the information provided, it is clear that Industrial IoT is more powerful than SCADA and will be fully replacing it any time sooner. The motto for any engineer is to have invariable access to accurate, impeccable data that aims to better decision attributes and stronger execution trends. Whether it is a small organization or a large industry both can avail the modern technology by partnering with Industrial IoT. Industrial IoT has already made its place in many sectors and is the future of industries.


It depends upon the perspective of the consumer whether they prefer SCADA systems or IoT systems. But the fact that IoT is more powerful and has many more promising features cannot be denied. Industrial IoT are less complex than SCADA.

Industries that still use SCADA systems are – Water Systems, Oil and Gas Industries, Food Production Industries and many more.

Internet of Things (IoT) is important because it can develop information about linked objects, analyze the situation, and take an appropriate decision. With an affordable cost Industrial IoT gives phenomenon and satisfying results.
