Optimising multi-cloud performance with peering strategies

Modern businesses are no longer confined to a single cloud provider. With growing application demands and distributed workloads, multi-cloud connectivity has become the backbone of digital transformation. However, the complexity of interconnecting multiple clouds brings challenges in performance, latency, visibility, and cost. To overcome these, enterprises are adopting smarter network peering strategies that ensure seamless, secure, and cost effective connectivity between clouds.

The right peering model can transform your multi-cloud architecture, enabling consistent user experiences, predictable performance, and significant cost savings. Tata Communications, through its intelligent architecture and advanced multi-cloud connect demo, showcases how enterprises can set up reliable cloud connections in less than ten minutes, achieving agility and scalability without compromising on performance.

Why network performance matters in MCC

In a multi-cloud connectivity setup, even milliseconds of delay can impact application performance, productivity, and user experience. Every cloud provider has its own routing paths, bandwidth policies, and data egress costs. Without optimised peering, data must travel through the public internet, exposing traffic to congestion, unpredictable latency, and security risks.

When performance bottlenecks occur between clouds, applications slow down, data transfer costs rise, and service reliability suffers. By implementing strategic network peering, enterprises gain direct, high throughput routes between clouds, reducing latency and jitter while enhancing stability.

The key objective is to ensure predictable and consistent performance across environments, whether data moves from cloud to cloud, from data centre to cloud, or from branch to cloud.

Role of peering in enhancing intercloud traffic

Network peering plays a vital role in facilitating direct communication between cloud environments. Instead of routing data through the public internet, peering creates private connections between cloud providers or between an enterprise and a provider. This not only reduces dependency on third party internet routing but also enhances performance, security, and visibility.

Through Tata Communications’ IZO^TM plus platform, enterprises can set up inter cloud connections on demand, automatically provisioning bandwidth and routing policies to ensure smooth traffic flow. Such intelligent architectures help mitigate performance unpredictability while reducing egress costs by up to forty percent.

By applying efficient peering models, data transfer becomes faster, safer, and more cost efficient, ensuring that every workload performs at its best.

Bilateral peering: direct provider-to-provider routing

Bilateral peering involves establishing a direct connection between two specific networks or cloud providers. This is the most traditional form of network peering, where each party agrees to exchange traffic directly without any intermediary.

The key advantages of bilateral peering include:

• Predictable performance: Data follows a fixed, private route, reducing latency and jitter.
• Enhanced security: Direct connections bypass the public internet, minimising exposure to threats.
• Custom traffic management: Each provider can control routing policies for optimal throughput.

Bilateral arrangements work best when two clouds exchange significant volumes of traffic or when specific workloads demand low latency. However, managing multiple bilateral agreements can become complex as the number of cloud environments increases.

In the Tata Communications ecosystem, bilateral peering ensures that enterprises enjoy direct, high performance connections across major cloud providers, ideal for mission critical applications such as data analytics, online transactions, or real time customer engagement.

Multilateral peering: simplified scalable interconnects

While bilateral arrangements provide control, they can be difficult to scale. This is where multilateral peering comes in.

Multilateral peering allows multiple cloud providers, networks, and enterprises to interconnect through a single exchange point, commonly a carrier neutral hub. Instead of managing dozens of one to one agreements, a single multilateral setup provides access to many participants simultaneously.

Benefits include:

• Simplified operations: One connection gives access to multiple peers.
• Cost efficiency: Reduced administrative overheads and shared infrastructure.
• Scalability: Easy to add or remove peers as requirements evolve.

For organisations running diverse workloads across AWS, Azure, and Google Cloud, multilateral peering delivers flexibility without the complexity of managing multiple links. Tata Communications’ global presence across internet exchanges and PoPs enables such scalable interconnects to deliver secure, reliable, and high performance multi-cloud connectivity.

When to use bilateral vs multilateral (Decision matrix)

Choosing between bilateral peering and multilateral peering depends on your performance, scale, and cost requirements.

In short, choose bilateral peering when performance and control matter most. Opt for multilateral peering when scalability, simplicity, and cost savings take priority. Many enterprises deploy a hybrid approach, leveraging both models for different workloads.

Best practices: routing, cost, redundancy

To achieve true high performance multi-cloud connectivity, follow these architectural best practices:

1. Optimise routing paths: Ensure shortest path routing between clouds. Use intelligent traffic steering to avoid congestion.

2. Manage costs actively: Monitor bandwidth utilisation and egress fees. Implement peering strategies that lower overall data transfer costs.

3. Build redundancy: Always design dual paths for failover. Redundant network peering links ensure business continuity during outages.

4. Automate provisioning: Use platforms like Tata Communications Core Connectivity plus that allow provisioning of bandwidth and routing policies within minutes.

5. Monitor visibility: Employ end to end monitoring to track performance, latency, and cost across all clouds.

Following these principles ensures agility and resilience while maximising return on investment.

Beyond peering: other ways to improve MCC (Edge nodes PoPs SDN)

While network peering forms the foundation, several complementary technologies further enhance multi cloud connectivity.

• Edge nodes: Deploy compute and storage closer to end users to reduce latency and accelerate response times.
• Points of Presence (PoPs): Extend your network’s global reach. Tata Communications’ global PoP network ensures consistent performance across continents.
• Software Defined Networking (SDN): Automate and manage your network dynamically. With SDN, you can allocate resources on demand and optimise routing in real time.

Together with bilateral peering or multilateral peering, these technologies enable an intelligent, adaptive, and secure cloud network that performs at scale.

Conclusion: choosing the right strategy

Optimising multi cloud performance is not about selecting one perfect model but about architecting flexibility. Bilateral peering ensures control and low latency where it matters most. Multilateral peering provides scalability and simplicity across diverse workloads. Combining these with edge computing, PoPs, and SDN creates a truly intelligent network fabric.
