Benefits of Using GCP Interconnect for Cloud Connectivity

With Tata Communications as your trusted network partner, leveraging GCP Dedicated Interconnect or Direct Interconnect GCP ensures unmatched performance, reliability, and security for your cloud journey.

• Low Latency and High Throughput:

With GCP Interconnect, your data bypasses the public internet and travels through dedicated high-bandwidth routes. This dramatically reduces latency and improves throughput—which is critical for businesses running real-time applications, data-intensive workloads, or latency-sensitive services.

• Reliable and Consistent Performance:

Since the traffic moves directly between your on-premises network and Google Cloud, you benefit from a highly stable and consistent connection. Tata Communications ensures this reliability through global reach and industry-leading service standards.

• Redundancy and High Availability:

Interconnect offers support for multiple physical links and routing diversity. Tata Communications designs each connection with built-in redundancy to minimise any risk of downtime, ensuring your applications remain available when you need them most.

• Scalable Capacity:

Based on your bandwidth requirements, you can start with 10-Gbps or scale up to 100-Gbps Ethernet connections. Tata Communications offers flexible scaling options, allowing you to grow your infrastructure without disruptions.

• Private and Secure Connectivity:

Your data remains within a private, controlled path by avoiding the public internet. Tata Communications further enhances this with advanced encryption, secure access policies, and full compliance with global security standards.

• Cost Efficiency:

GCP Interconnect through Tata Communications can significantly reduce your gcp egress costs and network costs. With fixed port pricing, you gain predictable monthly costs, simplifying budgeting and eliminating surprises.

• Simplified Network Management:

Direct connectivity between your data centre and Google Cloud means fewer intermediaries, reduced complexity, and easier network control. Tata Communications offers managed services to streamline operations further, leaving you free to focus on your business.

Comparing GCP Interconnect with Other Cloud Interconnect Solutions

When it comes to connecting your on-premises network to the cloud, each cloud provider offers its own interconnect solution. Let's understand how Direct Interconnect GCP or GCP Dedicated Interconnect compares with similar options from other providers.

• Connection Type

GCP Dedicated Interconnect provides a direct, private connection between your data centre and Google Cloud. Similarly, AWS offers Direct Connect, and Azure offers ExpressRoute. While all three avoid the public internet, GCP stands out for its flexible bandwidth options and lower latency routing across Google's global fibre network.

• Bandwidth and Performance

With GCP, you can scale from 10 Gbps to 100 Gbps, matching enterprise workloads. Google's backbone is known for its speed and reliability, making it ideal for real-time apps and large data transfers. Azure and AWS also offer high-capacity options, but GCP's performance is often more consistent due to its tightly controlled infrastructure.

• Pricing Structure

GCP Interconnect offers straightforward, fixed port pricing, which helps manage costs better. AWS and Azure can have more layered or region-dependent pricing, which sometimes adds complexity to forecasting bills.

• Setup and Integration

GCP's integration with its native services is seamless. Whether you're running hybrid applications or migrating workloads, GCP makes the process smooth. AWS and Azure also provide integration, but GCP is known for its developer-friendly tools and quicker setup.

• Global Reach

All three cloud providers have wide global coverage, but Google's extensive edge presence and robust fibre network provide exceptional reach and stability, especially for enterprises with users or sites across the globe.

In summary, GCP Dedicated Interconnect is a strong choice if you need high-speed, reliable, and cost-effective cloud connectivity. Unlike standalone interconnects, MCC lets you centrally manage ExpressRoute, Direct Connect, and GCP Interconnect together—using a single policy framework and analytics dashboard Backed by Tata Communications' expertise, you get a fully managed, secure, and globally optimised connection for your enterprise needs.

Best Practices for Implementing GCP Interconnect

At Tata Communications, we help enterprises get the best out of their GCP Dedicated Interconnect by not just enabling reliable connectivity but also guiding on key practices that ensure security, compliance, and performance. Here are some essential practices to follow.

• Start by ensuring that you have a sufficient log data retention period. Logs are critical for auditing, troubleshooting, and compliance, so keeping them for an appropriate duration is vital.
• Use Bucket Lock to configure retention policies. This ensures logs can't be deleted before the retention period ends, adding an extra layer of control.
• Enable global logging to ensure that activities are tracked across all regions and services, offering a complete view of your network operations.
• For better security, enable Logs Router encryption using your own customer-managed encryption keys, giving you full control over how logs are protected.
• Lastly, always monitor any changes made to audit configurations or bucket permissions, helping to detect and respond to unauthorised modifications quickly. 

MCC also simplifies compliance mapping across cloud services, ensuring your GCP traffic policies align with enterprise-grade standards from day one.
