Highlights
- Smooth information sharing keeps government services running smoothly, and interoperability is at the heart of this.
- Interoperability could include - interoperable data sources, timely access between and within systems, information exchange, and harmonious infrastructure.
- The benefits of a multi-cloud strategy include access to different technologies from different providers, the ability to negotiate costs, and reduced risk of downtime or data loss.
Interoperability at the heart
Smooth information sharing keeps government services running smoothly, and interoperability is at the heart of this.
By interoperability, we mean - interoperable data sources, timely access between and within systems, information exchange, and harmonious infrastructure.
Benefits of interoperability
The benefits of a multi-cloud strategy include access to different technologies from different providers, the ability to negotiate costs, and reduced risk of downtime or data loss.
Let’s explore the breadcrumbs that public sector organizations can follow to find their way to interoperability in a multi-cloud environment with a quick investigation into the interoperability options from the hyperscalers below:
- API management and gateways are offered as platform-as-a-service, supporting the complete API lifecycle, with policies to control how data is exposed to external systems within and across cloud platforms.
- Data transfer between cloud providers through site-to-site VPN or via a private network to facilitate network connectivity between workloads and services across cloud platforms.
- Data integration to orchestrate movement and transformation of data between data stores. Data integration services are primarily designed for ETL (Extract, Transform, Load) within the same cloud environment.
- Backend process logic workflows with visual integration platform-as-a-service (iPaaS) options to help you connect and bring together disparate systems. You can build distributed applications and orchestrate microservices (currently cloud provider-specific).
- Message-driven communication to send and receive messages between cloud applications. While primarily designed for sending notifications within each hyperscaler’s own cloud ecosystem, it is possible to achieve cross-cloud communication by setting up a custom solution.
- Event-driven architectures for point-to-point integration between event producers and consumers. To integrate directly between cloud providers, you must create a custom bridge via APIs to connect two event systems. We are seeing some published reference architectures in this area from the hyperscalers.
- Serverless functions to execute code in response to events. Hyperscaler services are not designed for cross-cloud orchestration and will require custom solutions that may be challenging to debug and optimize.
Other than at the network connectivity level, Cloud providers facilitate interoperability with API services.
This includes new services such as Amazon Q Gen AI Chatbot. To integrate Amazon Q with Azure, for example, you need to create a custom plugin that uses natural language to query data in Azure and take action in Azure-hosted applications.
API management services support some of the latest query languages, such as GraphQL. This allows clients to request and receive only needed data, leading to more efficient data retrieval and reduced network overhead associated with REST.
Conclusion
Governments are improving citizen experiences with a single login, data marketplaces, and publishing toolkits and guidelines consistent across domains and localities.
We are seeing significant progress from the major cloud providers. They publish interoperable reference architectures and release services supporting bi-directional data flow with SaaS providers (such as Salesforce, SAP, and ServiceNow).
Each buying organization still has responsibility for managing the interoperability challenge in a multi-cloud environment. This includes evaluating integration architecture choices, maintaining security measures, ensuring data integrity after data exchange, testing, error handling, and not overcomplicating integration solutions with excessive customization.
For now, independent iPaaS tools might be the easiest path to integrate multi-cloud services. These tools provide a unified interface and pre-built connectors to simplify the integration process, combining APIs and messaging to create integrated workflows for applications and services.
