AWS Services for Networking and Connectivity
White-label network architecture across AU, UK, and SG. We design the VPC topology, hybrid connectivity, and DNS layer that every other AWS service your client runs actually depends on.
From multi-AZ VPC architecture and Transit Gateway design to Direct Connect hybrid connectivity, Route 53 traffic management, CloudFront edge delivery, and layered network security. Delivered under your agency brand.
The AWS Services Nobody Notices Until the Network Design Is Wrong
Most AWS services environments we inherit were never designed as a network, they accumulated. A VPC gets created for the first project, a second VPC gets created for the next one with an overlapping CIDR range nobody checked, and by the time a client needs the two to talk to each other, peering is off the table and the only fix is re-addressing one of them while production traffic is live. None of this shows up in a demo. It shows up eighteen months later when the business needs two environments connected and discovers the addressing plan was never actually a plan.
We treat VPC CIDR allocation, subnet tiering, and hybrid connectivity as foundational decisions made once and planned for years of growth, not configured per project as each new requirement appears. Getting the address space and routing strategy right before the first AWS services workload deploys is the difference between a network that scales and one that needs re-architecting under pressure. See how this approach has delivered for our clients across our case studies.
AWS Networking and Connectivity Services
Six specialist capabilities. One engineering team designing the network layer every other AWS service your client runs depends on.
VPC Architecture and Multi-AZ Subnet Design
We design VPC CIDR allocation across accounts with enough address space for years of growth, not just the current project, the same discipline we apply across every AWS services engagement, following AWS’s VPC design guidance. Subnets are tiered by function, public for internet-facing load balancers, private for application compute, isolated for databases, spread across at least two availability zones so a single AZ failure does not take down the whole workload.
AWS Transit Gateway for Multi-VPC Connectivity
Transit Gateway replaces a sprawling mesh of point-to-point VPC peering connections with a single routing hub, which matters once an organisation runs more than a handful of VPCs across multiple accounts. We design route table segmentation so workloads that should not communicate stay isolated even though they share the same transit hub, and configure inter-region peering for organisations running infrastructure across more than one AWS region.
AWS Direct Connect for Hybrid Connectivity
Direct Connect provides dedicated, private network connectivity between on-premises infrastructure and AWS, bypassing the public internet entirely for latency-sensitive or compliance-driven hybrid workloads. We configure BGP routing with appropriate AS path prepending for failover behaviour, set up Direct Connect Gateway for connectivity across multiple regions, and design Site-to-Site VPN as a backup path so a single circuit failure does not sever hybrid connectivity entirely.
Amazon Route 53 DNS and Traffic Management
Route 53 handles more than basic DNS resolution. We configure weighted routing for gradual traffic shifts during deployments, latency-based routing for multi-region applications serving users across different geographies, and health check-driven failover so DNS automatically routes away from an unhealthy endpoint without manual intervention. Private hosted zones are configured for internal service discovery that should never resolve from the public internet.
Amazon CloudFront CDN and Edge Delivery
CloudFront distributes static and dynamic content from edge locations close to end users, reducing latency and offloading traffic that would otherwise hit origin servers directly. We configure origin failover between primary and backup origins, cache behaviour tuned per content type so dynamic API responses are not cached when they should not be, and AWS WAF integration at the edge to block malicious traffic before it ever reaches application infrastructure.
Security Groups, NACLs and AWS Network Firewall
Security groups provide stateful, instance-level filtering scoped tightly to actual traffic requirements rather than broad rules nobody has revisited since launch. Network ACLs add a stateless subnet-level layer for defence in depth. For organisations needing centralised, inspection-grade filtering across a Transit Gateway-connected environment, we deploy AWS Network Firewall, one of the more overlooked AWS services for centralised inspection, with rule groups that apply consistently regardless of which VPC traffic originates from.
Our Address-Plan-First Approach to AWS Network Design
We do not start by provisioning AWS services in isolation, beginning with a VPC because a project needs one. Every engagement starts with an IP address plan covering every VPC the organisation expects to run over the next several years, not just the one in front of us today. Getting this wrong is one of the more expensive mistakes to fix in AWS networking, because re-addressing a live VPC means touching every resource inside it.
From the address plan, we design the connectivity model for every AWS services workload that will sit behind it, whether workloads need Transit Gateway, simple peering, or no inter-VPC connectivity at all, and the routing and security boundaries follow from that decision rather than being bolted on afterward. To scope your client’s AWS network architecture, book a discovery call, and we return a preliminary scope within a week.
Capabilities We Bring to Every AWS Networking Engagement
PrivateLink architecture, DDoS protection, cost-aware connectivity choices, and traffic visibility built into the design from day one.
VPC Peering and PrivateLink Architecture
VPC peering for simple, low-volume connectivity between a small number of VPCs, and AWS PrivateLink for exposing a service to other VPCs or accounts without the connectivity, routing, and security group complexity that full peering introduces. We choose between the two based on whether the relationship is genuinely peer-to-peer or actually a service being consumed by multiple unrelated consumers.
DDoS Protection with AWS Shield
AWS Shield Standard protects every AWS customer by default against common network and transport layer attacks at no additional cost. For workloads with a genuine business case for stronger guarantees, we configure Shield Advanced with cost protection for scaling charges incurred during an attack and direct access to the AWS DDoS Response Team, justified against the actual risk profile rather than added as a default upsell.
Cost-Aware Connectivity Decisions
NAT Gateway hourly and data processing charges add up quickly for high-traffic outbound workloads, and we evaluate NAT instance alternatives or VPC endpoint usage to avoid unnecessary NAT traversal for AWS service calls. Direct Connect versus Site-to-Site VPN is evaluated on actual bandwidth and latency requirements rather than defaulting to the more expensive option because it sounds more robust.
Network Observability with Flow Logs and Traffic Mirroring
VPC Flow Logs enabled and routed to a queryable destination for traffic pattern analysis and security investigation, with Traffic Mirroring configured for deep packet inspection on specific high-value workloads where Flow Logs metadata is not detailed enough to diagnose an issue.
AWS Networking Services Delivered Under Your Agency Brand
We work as the invisible engineering layer behind your agency’s AWS networking delivery. Our engineers design the address plan, configure Transit Gateway and hybrid connectivity, set up DNS and CDN, and produce architecture documentation in your agency’s format. Your clients receive a network that scales with their actual growth and with every new AWS services workload added to it, not a VPC created once and never revisited until it becomes a constraint.
Our white-label development model is built for agencies managing multiple clients’ AWS network estates. You scope confidently knowing the technical delivery is handled by engineers who’ve designed Transit Gateway topologies and hybrid connectivity before. For agencies running several concurrent AWS networking projects, our agency partner programme provides priority access to our network engineering team, preferred project rates, and a dedicated account contact across all active client engagements.
Why AWS Network Designs Fail Quietly Until Growth Exposes Them
The most common pattern: every new project gets its own VPC with whatever CIDR range was convenient at the time, and nobody tracks address allocation across the organisation. The first time two business units need their environments connected, peering fails because the ranges overlap, and the only paths forward are re-addressing one VPC under live traffic or building NAT-based workarounds that add latency and complexity nobody wanted. This kind of problem compounds across every AWS services deployment that follows, and it is entirely avoidable with a CIDR allocation plan made once at the start, and entirely painful to fix once dozens of resources already depend on the existing addressing.
The second pattern: security groups accumulate broad rules over a project’s lifetime because tightening them later risks breaking something nobody fully understands anymore. A rule allowing access from 0.0.0.0/0 added during initial development never gets narrowed once the application is live, and it sits there as an open door until a security review finally flags it. Our AWS development services practice designs the address plan and security boundaries before the first workload deploys, not as a remediation project after growth or an audit exposes the gaps.
Engagement Models for AWS Networking Projects
Structured for agency delivery workflows. Scalable across your full client portfolio.
Network Architecture Sprint
A defined 3-to-5-week sprint covering address plan design, VPC and subnet provisioning, Transit Gateway setup where multiple VPCs are involved, and baseline security group and NACL configuration. Best for agencies whose clients need a properly architected foundation for their AWS services before scaling further, an AWS network foundation at the end of a fixed engagement.
Dedicated Network Engineer
A senior AWS network engineer embedded in your client project, designing VPC topology, configuring hybrid connectivity, and setting up DNS and CDN delivery. Operating in your project channels, producing documentation in your format. Available full-time or part-time depending on the project phase and current network complexity.
Hybrid Connectivity Retainer
A monthly retainer for agencies managing multiple clients’ hybrid AWS connectivity simultaneously. Covers Direct Connect circuit health monitoring, Transit Gateway route table reviews as new VPCs come online, security group audits, and periodic cost reviews of NAT and data transfer charges. Predictable monthly cost across your active client portfolio.
Multi-Account Network Build
A full greenfield network build for agencies setting up a client’s multi-account AWS environment from scratch, address planning across every account, Transit Gateway hub design, Direct Connect or VPN hybrid connectivity, and centralised Network Firewall inspection. Reach us via our contact page to discuss scope and timeline.
Our AWS Networking Delivery Process
Six phases from address planning to production handover, with sign-off gates before each build stage begins.
Phase 1 — Address Plan and Connectivity Assessment
We document every existing VPC, CIDR range, and connectivity requirement across the client’s AWS accounts, and design an address allocation plan sized for years of growth, not just current workloads. The output is an addressing and connectivity blueprint covering every current and planned AWS services deployment, your agency uses to set scope before any infrastructure is touched.
Phase 2 — VPC and Subnet Provisioning
VPCs and subnets deployed via CloudFormation or Terraform following the agreed address plan, with public, private, and isolated subnet tiers spread across multiple availability zones for resilience against a single zone failure.
Phase 3 — Transit Gateway and Hybrid Connectivity
Transit Gateway provisioned where multiple VPCs need centralised routing, with route table segmentation enforcing isolation between workloads that should not communicate. Direct Connect or Site-to-Site VPN configured for hybrid connectivity, with BGP routing validated for correct failover behaviour.
Phase 4 — Security Group, NACL, and Firewall Configuration
Security groups scoped to actual traffic requirements per workload, NACLs configured for subnet-level defence in depth, and AWS Network Firewall deployed where centralised inspection across a Transit Gateway-connected environment is required.
Phase 5 — DNS and CDN Configuration
Route 53 hosted zones configured with the appropriate routing policy per use case, weighted, latency-based, or failover, and CloudFront distributions set up with origin failover and cache behaviour tuned per content type for any workload needing edge delivery.
Phase 6 — Monitoring and Handover
VPC Flow Logs enabled and routed to a queryable destination, CloudWatch alarms configured for Direct Connect circuit health and Transit Gateway attachment status, and network architecture documentation delivered to your client’s team.
