Modern businesses operate in diverse technological environments, ranging from on-premise to distributed cloud solutions. Connecting these multi-platform environments efficiently, securely, and scalably is a significant challenge. Many organizations seek tools and solutions that promise to alleviate these connectivity difficulties, but they often find that a single solution doesn't address all their specific needs, especially considering the variety and complexity of constantly evolving integration scenarios.

Red Hat Service Interconnect has emerged as a solution to facilitate communication between multi-platform environments in various contexts. It fills a significant gap in the ecosystem by simplifying service-to-service connectivity, especially in multi-cloud and hybrid scenarios. However, it is essential to recognize that there is no single tool that serves as a "silver bullet" for all connectivity and integration challenges.

While Red Hat Service Interconnect offers clear advantages, like eliminating the need for complex VPNs and deeper integration with specific platforms, there are scenarios and requirements that might be outside its optimal scope. Some organizations might encounter specific needs, such as custom integrations, advanced security policies, or functionalities that go beyond what Red Hat Service Interconnect offers.Therefore, it's crucial for companies to conduct a thorough and careful assessment of their communication and integration needs.

Red Hat Service Interconnect might be a cornerstone in many scenarios, but it might not be the complete solution in others. Thus, when considering any tool, it's vital to balance enthusiasm and pragmatism, ensuring the chosen solution aligns well with the specific objectives and challenges of the organization. In technology, detailed understanding and adaptation are often the keys to success.

What is Red Hat Service Interconnect?

Red Hat Service Interconnect is a supported version of the open source project called Skupper. This type of technology makes it easy to connect applications and services between and on top of Kubernetes clusters, virtual machines, or bare metal.

Red Hat Service Interconnect Architecture and Functionality

Virtual Application Network (VAN) is a virtualized, application-centric network layer decoupled from the underlying network infrastructure. Its goal is to enhance application performance and agility by dynamically adapting to their needs and streamlining network management. Rather than focusing on traditional infrastructure, the VAN prioritizes application demands, offering an optimized user experience and more efficient network operation. Instead of merging the nodes of several clusters, Red Hat Service Interconnect sets up a VAN that facilitates communication on top of Kubernetes clusters, virtual machines, or bare metal. 

No Need for VPNs: VPNs often introduce latency and complexity. With Red Hat Service Interconnect, such abstractions are eliminated, focusing strictly on service connectivity.

Deep Technical Benefits of Red Hat Service Interconnect

  • No scope for common failures: By connecting services rather than clusters, Red Hat Service Interconnect isolates potential faults, preventing systemic propagation issues.
  • Standard encryption: Security is not an afterthought. With Red Hat Service Interconnect, all communications are encrypted out-of-the-box.
  • Flexible routing logic: Red Hat Service Interconnect routing logic lets engineers have granular control, optimizing for latency, redundancy, or other criteria as needed.
  • Resilience and scalability: Different clusters can be managed, scaled, or updated independently. Red Hat Service Interconnect keeps communication between the services intact, regardless of changes in the cluster environment.

Key Takeaways for Technology Vendors

  1. Differentiation in a crowded market: Red Hat Service Interconnect allows technology vendors to differentiate their offerings. By focusing on service rather than cluster connectivity, they can offer solutions that address unique challenges faced by large enterprises.
  2. Baked-in security: In a world where security breaches make headlines, Red Hat Service Interconnect out-of-the-box encryption gives vendors an edge when marketing to security-conscious clients.
  3. Customizable routing logic: Being able to offer customers the ability to fine-tune routing based on their specific needs, such as latency or redundancy, adds another layer of customization and value to vendor portfolios. It does not replace the existing layer 3 network.
  4. Promise of resilience: Vendors can emphasize Red Hat Service Interconnect's inherent resilience and scalability, ensuring clients that their inter-cluster communications will remain robust irrespective of cluster environment changes.
  5. Flexibility: It can be used on any Kubernetes, any virtual machine, any bare metal host and any public cloud and allows connectivity to be ported to other environments.

Differences between Red Hat Service Interconnect and VPN

Red Hat Service Interconnect and VPNs (Virtual Private Networks) are both solutions to connect networks and systems across different locations. However, their conception, design, and purposes have notable distinctions. Let's explore these differences:


Red Hat Service Interconnect


Primary Purpose

Primarily focused on connectivity between services across dispersed Kubernetes clusters. It's designed to enable service-to-service communication across different environments on top of Kubernetes clusters, virtual machines or bare metal.

Aims to create a secure channel between distinct networks, allowing them to communicate as if they were on the same local network.

Level of Abstraction

Operates at the application level, facilitating communication between specific microservices across different environments.

Operates at the network level, establishing a tunnel between entire networks.

Complexity and Overhead

Designed to be more lightweight and straightforward for service-to-service connectivity, often resulting in less overhead.

Can introduce additional latency and overhead due to encrypting all traffic and routing it through the tunnel.


It requires MutualTLS connectivity, guaranteeing a direct and secure tunnel to the services.

Ensures secure communication between two networks with certificates at both ends.

Implementation and Management

Simplified management with a web interface that doesn't require any understanding of routing; can be implemented on Kubernetes, virtual machines, and other types of platforms.

It can be complex to set up and consistently maintain based on the dynamically needs of the business

Flexibility and Routing

Allows for more flexible routing logic, optimized for latency, redundancy, or other service-based criteria.

More general in its routing approach as it operates at the network level.


Example of Use Cases

Multi-Cloud Scenarios

Companies with workloads spread across different cloud providers (such as AWS, Google Cloud, and Azure) might want their services to communicate without the need for complex VPNs. Red Hat Service Interconnect can bridge services across different cloud providers seamlessly.

Hybrid Environments

Organizations that operate in a hybrid model or are moving to the cloud (some workloads on-premises and others in the cloud) often face connectivity challenges. Red Hat Service Interconnect facilitates this service-to-service communication without exposing the entire network.

Development and Production

For teams with separate development, testing, and production environments (possibly in different clusters or networks), Red Hat Service Interconnect can facilitate continuous integration and delivery by enabling secure, direct communication between these environments.

Data Isolation and Compliance

Companies operating across multiple geographic regions and needing to comply with specific regional regulations regarding data storage and processing can use Red Hat Service Interconnect to ensure services communicate efficiently while data remains in the appropriate region.

Company Expansions and Mergers

When two companies merge or when one company acquires another, infrastructure integration challenges are common. Red Hat Service Interconnect can be a swift solution to bridge services and applications of both companies, without extensive infrastructure overhauls.

Edge Computing

For companies that operate edge computing models in which edge devices can have small gateways to make communication between applications and services simple and secure. Red Hat Service Interconnect can help connect these edge devices to central clusters, enabling real-time data communication and processing.

Final Thoughts

For professionals dealing with container orchestration at scale and seeking an optimized and effective solution, Red Hat Service Interconnect might be a crucial addition to their toolkit. It not only addresses the issue of interconnecting clusters but does so in a way that places performance, security, and robustness at the heart of its architecture. When facing multi-cloud or hybrid implementation challenges, Red Hat Service Interconnect could be the technical game-changer you need.
