Frequently Asked Questions

WHAT IS GOOGLE CLOUD INTERCONNECT? Google Cloud Interconnect is a set of services provided by Google Cloud Platform (GCP) that enables customers to establish private, high-performance connections between their on-premises infrastructure and Google Cloud.
WHAT IS THE DIFFERENCE BETWEEN GCI AND PEERING? Google Cloud Interconnect is focused on providing dedicated, private connections between your on-premises network and GCP. Peering establishes connections between different networks within GCP or between a Google Cloud network and external networks.
WHAT IS THE DIFFERENCE BETWEEN DEDICATED INTERCONNECT AND PARTNER INTERCONNECT? The dedicated approach involves a dedicated physical connection that isn’t shared with others. The interconnect partner approach involves an intermediary service provider such as a colocation data center and doesn’t require a direct physical connection.
HOW DOES CLOUD INTERCONNECT IMPROVE ENTERPRISE RESILIENCE? Cloud Interconnect improves enterprise resilience through the ability to configure redundant connections; the combination of low latency and high throughput; and predictable, consistent network performance.
WHO USES GOOGLE CLOUD INTERCONNECT AND WHY? Some of the users of GCI include enterprises with hybrid cloud deployments, media and entertainment companies that work with media files, healthcare organizations that require compliance with sensitive data regulations, any business that has fluctuating and/or seasonal compute requirements and enterprises with global operations that require consistent, efficient access to cloud resources.
HOW DOES CLOUD INTERCONNECT ACCELERATE DIGITAL TRANSFORMATION? Cloud Interconnect enables the seamless integration between on-premises infrastructure and cloud resources, allowing enterprises to place workloads strategically, and share data and applications. Access to cloud scalability overcomes traditional limitations of data center capacity, which can speed up go-to-market initiatives. Additionally, enterprises can move data to and from the cloud to satisfy regulations.
