2. Lack of Scalability
“Sensor-based IoT is driving an unprecedented data footprint explosion. Today, most of that data is discarded because it cannot be processed with the existing infrastructure. This marks an opportunity for flash to be a pillar for instant data analytics infrastructure...because [it] is capable of processing petabytes of data, enabling real-time decision-making.” -Michael Cornwell, Pure Storage
Issues with scaling IT resources are among the most common reasons for the collapse of IoT projects. According to Microsoft, one-third of businesses whose IoT project failed at the proof-of-concept stage cited a high scaling cost.
As we mentioned above, the IoT and big data go hand in hand. For these projects to succeed, there has to be enough bandwidth on the network and adequate data processing power to manage the influx of streaming data without crippling existing operations. Traditional architectures, including relational databases, aren’t normally suitable for developing larger IoT projects. Instead, they require a scalable, flexible, modern data storage solution with a non-relational database and adequate processing power to extract insights in real time.
Why Scalability Matters
Part of the challenge with traditional databases is that they use a fixed schema for performing queries. When you enter data into a traditional database, it must be “structured” so it’s compatible with the relational columns and rows accessed by a relational database management system (RDBMS).
IoT devices generate different types, however, and usually at high velocity. Traditional storage systems can quickly reach capacity when receiving this type of data. The data also needs to be processed, cleaned, and sorted for real-time analytics—and not every network is designed to support that.
Storage solutions using an RDBMS can become slow and cumbersome even before they reach capacity, as the index must update each time you insert a new record. Then, other operations become more resource-heavy as the relationships between database entries multiply.
Scaling Up vs. Scaling Out
When a traditional, centralized database hits capacity, your option is typically to scale up by buying additional servers and migrating data over.
Distributed databases allow you to scale “out” rather than “up.” Using a distributed database also means you can operate on commodity hardware. This allows you to scale by adding new servers—rather than swapping out existing servers for a bigger one.
There are immense advantages to scaling “out” for IoT projects. There’s no need to migrate your data to a new system or manage loads between multiple systems, and you can easily add or remove storage capacity as required.
3. Poor Security
Security concerns are another reason IoT projects can fail. You must implement security, encryption, and privacy-by-design principles into your IoT project at all stages—and in all aspects—of the development process.
For example, you can protect data that’s in transit and at rest (in storage) using AES-256 encryption. It’s recommended to use a storage provider that is certified under an official standard such as the Federal Information Processing Standards (FIPS).
Privacy Law Compliance
But that’s not all. Compliance with privacy law is another crucial consideration for any IoT project. Laws like the EU General Data Protection Regulation (GDPR), California Consumer Privacy Act (CCPA), and other regulations have major implications for data collection via IoT devices.
Part of privacy law compliance is implementing anonymization of data or security measures, such as encryption, as described above. But privacy laws also require that you do not collect unnecessary personal information—or that you seek user consent under certain circumstances.
Device Management
To the extent possible, implement strict security and privacy settings of IoT devices by default. Disallow the modification of these settings by the user where appropriate. And remember: A vulnerable IoT device can create backdoors into your network, opening you up to a slew of other concerns.
Weak passwords are a major cause of security incidents, and IoT devices are no exception. For consumer devices, you can’t force users to encrypt their home wifi networks, but you can require them to select passwords that are unique, unguessable, and changed regularly.
Avoid using deprecated, out-of-date, or insecure software components and libraries. Consider the security of operating systems, third-party software, and hardware supply chains. In addition, make sure you implement a secure mechanism for updating your IoT equipment. This should include device firmware validation and security controls like anti-rollback mechanisms, encryption of updates in transit, and security notifications.
Finally, ensure devices deployed in production have security support, including capabilities such as asset management, update management, systems monitoring, and secure decommissioning.
4. Data Gravity
All across the IoT, data is collected by edge devices. However, moving all of this data to another location can be costly. Data gravity means it is more efficient to move infrastructure to the point of data creation rather than moving data to existing infrastructure.
The key is an architecture with a single control pane that can support and provide visibility into IoT data preprocessing and use, both locally and at the edge—meaning, before any of it has been moved to your cloud storage or data centre.
