Choosing the Right IoT Platform Strategy: Build, Buy & Integrate, or Buy Off-the-Shelf

• By 2030 over 40 billion IoT devices will be connected worldwide, making platform choice a critical business decision, with IoT Platform (Software & Cloud services) accounting for approximately 5-15% of the final product cost.
• The Internet of Things (IoT) has transformed how businesses collect, process, and** leverage device data**.
• When developing an IoT strategy, organizations face a critical decision: should they build a custom platform, buy an off-the-shelf solution, or pursue an integration approach?
• This article explores these three strategies, with a special focus on AWS IoT Core as a compelling option for businesses.

Build from Scratch

Best for: Businesses with unique requirements, deep technical expertise, and the resources to develop and maintain an IoT ecosystem.

The Build from Scratch approach offers full customization and control, but requires a significant investment in time and technical resources. This is best suited for organizations with strong in-house teams and long-term scalability ambitions.

Pros	Cons
Complete control – Full ownership over architecture, security, and customization.	High costs – Significant investment in development, infrastructure, and maintenance.
No third-party dependencies – Avoids vendor lock-in.	Long time to market – Development cycles can be lengthy.
Highly tailored solution – Built to meet specific business needs.	Technical complexity – Requires deep expertise in IoT, cloud, and security.
Potential competitive advantage – Unique features can differentiate the business.	Ongoing maintenance burden – Responsible for system updates, security, and scalability.

Buy & Integrate

Best for: Companies that want to leverage existing IoT services while maintaining flexibility to customize and scale.

This approach offers a flexible and efficient balance between rapid deployment and customization. It reduces the burden of building from scratch while maintaining the ability to tailor the platform.

Pros	Cons
Faster time to market – No need to build core IoT infrastructure.	Customization effort – Requires integration work to meet specific needs.
Scalability & Security – Managed platforms handle device connectivity, messaging, security, and data processing.	Vendor lock-in risk – Dependence on third-party services and pricing models.
Cost-Effective – Reduces upfront costs by leveraging existing infrastructure.	Ongoing costs – Subscription and usage-based pricing may accumulate over time.
Ecosystem support – Pre-built integrations with cloud services, analytics, and AI tools.	Limited control – Certain features and configurations may be restricted by the provider.

Buy Off-the-Shelf

Best for: Companies looking for an out-of-the-box solution with minimal customization.

This is ideal for businesses seeking fast implementation with lower technical complexity, though it sacrifices long-term flexibility.

Pros	Cons
Quickest implementation – No development required.	Limited customization – May not fit all business needs.
Predictable costs – Typically a subscription-based pricing model.	Scalability concerns – Some platforms may not be as flexible for long-term growth.
Lower maintenance burden – The provider handles updates, security, and support.	Potential feature bloat – Paying for features that may not be needed.
