2. Kinvey

Kinvey has been a leader in mobile Backend as a Service (mBaaS) for over six years. It connects mobile, web, and IoT apps to backend resources using unified APIs and SDKs. Built on a microservice architecture and a serverless cloud platform, Kinvey is designed to automatically scale based on demand. Let’s dive into how Kinvey handles IoT data.

IoT Data Storage

When it comes to data storage, Kinvey takes a smart approach by offering federated access to both enterprise and cloud services. Instead of forcing organizations to migrate their existing data, it connects IoT applications to current backend systems through unified APIs. Its RapidData services simplify integration with major enterprise platforms like SAP and Salesforce, as well as various NoSQL databases, eliminating the need for complex API development.

Kinvey also ensures secure access to internal data sources with its Secure Gateway, which establishes encrypted connections to systems like Microsoft SQL Server - no need to tweak firewalls or set up VPNs. Plus, its client SDKs provide strong offline capabilities, including two-way synchronization between devices and backend datastores. This ensures data stays consistent, even when the network is unreliable.

Data Processing and Real-Time Analytics

Kinvey uses FlexServices, lightweight Node.js microservices, to integrate data and business logic while leveraging the vast NPM ecosystem. This setup supports advanced data processing workflows and real-time analytics. The Kinvey Microservice Framework allows for scalable and modular development, abstracting the complexities of backend systems. This means developers can focus more on frontend work, as highlighted in the platform's documentation:

development teams no longer need to know the nuances of enterprise systems data access paradigms, allowing them to focus 100% on frontend work.

Security and Compliance

Security is a top priority for Kinvey. Its RapidAuth services connect applications to existing identity and single sign-on solutions, supporting various authentication protocols like OAuth2, SAML, OpenID Connect, Active Directory, LDAP, and even Facebook Auth. For added protection, the Secure Gateway enables encrypted connections to internal data sources without exposing them to the internet. This feature is especially critical for industrial IoT applications that handle sensitive operational data.

Integration and Ecosystem Support

The Kinvey high productivity platform makes it easy for Node developers to create native apps across multiple platforms while staying in control.

Kinvey’s RapidServices framework offers low- to no-code tools to simplify integration between IoT apps and existing business systems. Its Command Line Interface (CLI) integrates seamlessly into CI/CD pipelines with tools like Jenkins and Travis, allowing teams to store application metadata in version control systems like GitHub for consistent deployments. Additionally, by abstracting backend complexities, Kinvey creates a reusable service catalog that shields frontend developers from the intricacies of enterprise system integration. This ensures IoT applications remain adaptable to future backend updates.
