Data Centres & Hosting

Data centres are where the internet lives. We design and operate the network fabric that makes them run — high-density, high-availability, and built for the demands of modern hosting environments.

Data Centre Networking Is Where Architecture Decisions Have the Longest Consequences.

AMROTS works with data centre operators, colocation providers, managed hosting companies, and enterprises with private data centre infrastructure on the network fabric that underpins their entire operation. In a data centre environment, the network isn’t just infrastructure — it’s the product. Every tenant, every workload, every SLA commitment depends directly on the fabric performing reliably, at scale, without interruption.

The networking demands of modern data centres are significant. High-density server connectivity, east-west traffic patterns from virtualised and containerised workloads, multi-tenancy requirements, data centre interconnect between sites, and the operational complexity of managing a fabric that dozens or hundreds of customers depend on simultaneously — these are challenges that require specialist expertise, not general-purpose networking knowledge.

We design and deploy EVPN-VXLAN spine-leaf fabrics on Juniper JunOS and Arista EOS platforms — the architectures and platforms that power the world’s most demanding data centre environments. We bring the same carrier-grade engineering discipline to data centre networking that we apply to backbone and WAN work, because at data centre scale, the standard for precision and reliability is the same.

Frequently Asked Questions

Some of the questions we hear most from data centre and hosting clients

When should a data centre operator move from a traditional three-tier architecture to spine-leaf?
When east-west traffic patterns start to dominate, when spanning tree is causing operational pain, when you need to scale beyond what your current core can handle, or when you're planning a significant hardware refresh. The transition to a spine-leaf fabric is a significant undertaking — but the operational benefits are substantial and the architecture scales in ways that a traditional three-tier simply doesn't. We'll give you an honest assessment of whether the timing is right for your environment.
What platforms do you recommend for data centre fabric design?
Our primary data centre fabric work is on Juniper JunOS and Arista EOS — two of the most capable and widely deployed platforms in the data centre space. Both support EVPN-VXLAN natively, have excellent operational tooling, and are proven at the largest scales. Platform selection ultimately depends on your existing environment, operational team familiarity, and specific feature requirements — and we'll give you a vendor-neutral assessment of the right choice for your situation.
Can you migrate our existing data centre fabric to EVPN-VXLAN without taking production offline?
Yes — live migration from a legacy architecture to EVPN-VXLAN is one of the most complex projects in data centre networking, and it requires exhaustive planning and disciplined execution. We document the existing environment thoroughly, design a staged migration sequence that keeps workloads online throughout, and maintain rollback procedures at every step. We've planned migrations of this type and know exactly where the risk concentrates.
How do you handle multi-tenancy in an EVPN-VXLAN fabric?
EVPN-VXLAN provides native multi-tenancy through VNI separation and per-tenant VRF routing instances — isolating tenant traffic at the fabric level without requiring physical separation or complex VLAN management across the entire infrastructure. We design VNI allocation schemes and VRF architectures that scale cleanly as your tenant count grows, with clear operational procedures for provisioning new tenants.
Can you help us connect multiple data centres or extend our fabric to the cloud?
Yes — Data Centre Interconnect (DCI) extends your EVPN-VXLAN fabric between sites, maintaining layer 2 and layer 3 consistency across physical facility boundaries. For cloud connectivity, we design and deploy dedicated interconnects to AWS, Azure, and Google Cloud — and have deep experience with Cloud On-Ramp providers like Megaport for flexible multi-cloud access from co-location facilities.
What does managed operations look like for a data centre networking environment?
We provide 24/7 monitoring of your fabric — device health, BGP session stability, link utilisation, and tenant connectivity — with senior engineer on-call response for incidents. We also handle ongoing operational tasks: VXLAN tenant provisioning, firewall policy updates, capacity reviews, and fabric software upgrade programmes. Think of us as your dedicated network operations team, without the overhead of building one in-house.

How We Help Data Centre & Hosting Clients

From fabric design to managed operations — here’s where we add the most value for data centre and hosting environments.

Our Expertise

With Our Experience, We Understand the Complexity of Operating Data Centre Network Infrastructure.

Data centre operators face a unique combination of engineering challenges — high-density scale, multi-tenancy, continuous availability requirements, and the operational complexity of managing infrastructure that dozens or hundreds of customers depend on simultaneously. We bring the depth of expertise to address these challenges directly.

Designing spine-leaf fabrics that eliminate spanning tree, enable ECMP load balancing, and scale without re-architecture.
Building EVPN-VXLAN overlay architectures that support multi-tenancy cleanly at the fabric level.
Engineering high-availability server connectivity using ESI-LAG and MLAG for active/active redundancy.
Connecting data centres and cloud platforms with private, dedicated DCI and cloud interconnect solutions.
Migrating legacy three-tier architectures to modern spine-leaf fabrics without disrupting production workloads.
Providing managed operations and 24/7 monitoring for data centre fabrics with senior engineer response .

Our Approach

We Are Engineers First. Data Centre Fabric Design Demands Nothing Less.

Data centre network architecture decisions have consequences that last years — sometimes decades. We approach every data centre engagement with the rigour and attention to detail that the environment demands, from initial discovery through to post-deployment verification and ongoing operations.

We document existing data centre infrastructure thoroughly before recommending any changes — physical topology, switching configuration, VLAN design, server connectivity patterns, tenant requirements, and all dependencies that would affect a migration or upgrade.

For greenfield fabric designs, we produce detailed architecture documentation covering physical topology, BGP underlay design, EVPN-VXLAN overlay, VNI allocation, VRF design, and server connectivity — with a clear rationale for every decision and a growth plan that accommodates your expected scale trajectory.

For migration engagements, we design staged cutover sequences that move workloads from legacy architecture to the new fabric progressively — maintaining production availability throughout and providing documented rollback procedures at every step of the migration.

Post-deployment, we provide ongoing managed operations — fabric monitoring, tenant provisioning support, capacity planning, and software upgrade programme management — so your data centre network is always in the hands of engineers who understand it at the deepest level.
