Lifting Your Legacy SCADA to the Cloud – an Azure Approach

When it comes to manufacturing and utilities, legacy applications have considerable sticking power. For example, a substantial number of manufacturers are still using legacy SCADA (Supervisory Control and Data Acquisition) systems. These legacy systems are unable to keep up with the speed demanded by information technology in the era of industry 4.0 – and they’re also dramatically vulnerable to cyberattacks. A recent survey by Kasperksy labs shows that almost 43% of industrial control systems (ICS, of which SCADA is a subset) were attacked or infected by malware last year.

Lift and Shift to Azure for Manufacturers


What is SCADA

SCADA and ICS are traditionally based in on-premises appliances that are directly connected to assembly lines or capital equipment. In other words, it’s the exact opposite of cloud-based software. Increasingly, however, industrial information technology professionals are considering how to move these systems to the cloud, where they would gain the benefits of security, ease of use, and increased efficiency.


Why Would You Consider a Cloud SCADA?

The first reason to consider lifting your SCADA to the cloud is the sheer difficulty of maintaining an up-to-data SCADA system. On-premises SCADA depends on a connection to a PC in order to receive updates and patches. Once your PC software goes out of date, your SCADA will no longer be able to receive software updates. For example, if your SCADA is connected to a PC running Windows 7 – which is shortly going end-of-life – you’ll probably need to purchase a paid upgrade to your SCADA system in order to receive updates from a PC running Windows 10.

Windows 7 end of life


Based on this difficulty, it’s not hard to understand why many administrators simply choose to let their SCADA systems go out of date.

Now, let’s move to the cloud. Obviously, you still have to have some kind of physical sensor attached to your equipment, but much else can be moved to the cloud. Instead of connecting the SCADA to a PC that goes out of date, you connect the SCADA to a server in the cloud. The interface lives in the cloud, the data that the SCADA generates lives in the cloud, and operators can now access the SCADA from any device – including tablets and mobile devices.


Lifting and Shifting your SCADA via Microsoft Azure

If you’re a cloud skeptic, you may know that it’s one thing to espouse the benefits of the cloud, but it’s another thing to place your infrastructure there. If you choose the wrong infrastructure or the wrong methods, then your digital transformation may drag for years, balloon over budget, and fail to achieve a return on investment. According to some estimates, companies waste up to 35% of the budget that they allocate for cloud resources.

Fortunately, Azure represents one of the best platforms when it comes time to easily “lift and shift” your existing on-premises IT infrastructure to a cloud environment. In a SCADA context, that means taking the applications that your SCADA is reporting to, lifting them out of their on-premises environment, and shifting them to a new hosting infrastructure.

Azure is flexible and affordable


Why choose Azure? First of all, there’s cost. Cost-benefits are one of the main reasons that companies choose to switch to the cloud, and Azure is up to five times less expensive than its leading competitor. In addition, if you’re already using Windows Server and SQL Server (which you probably are, as many SCADA systems are connected to SQL databases), then your Azure cost will be further reduced.

In addition, Azure is flexible even if you aren’t using Windows products already. If your SCADA product is based on RedHat Linux, for example, then you’ll find that Azure has native support for the operating system built in already.

Finally, Azure is gentle on those who are new to the cloud. If you have information technology expertise on-premise, those skills will map onto the controls that Azure provides its cloud users. Thus, it’s not only easy to get started with Azure, it’s also easy to iterate on it once you’ve finished moving your applications there.
