AWS Web Services for Application Delivery
White-label web application delivery across AU, UK, and SG. We build the load balancer, API gateway, TLS, WAF, and hosting layer that sits between your client's users and their application logic.
From Application Load Balancer listener rules and API Gateway throttling to AWS WAF bot protection, Certificate Manager TLS automation, S3 and CloudFront static web app hosting, and App Runner. Delivered under your agency brand.
The AWS Web Services Delivery Layer Gets Blamed for Problems That Started Elsewhere
When a web application starts returning errors or slowing down under load, the load balancer usually gets investigated first because it’s the visible entry point. Most of the time the problem is not the AWS web services delivery layer itself. It’s an ALB health check threshold configured too generously so unhealthy targets stay in rotation longer than they should. Or an API Gateway throttling limit set to a default nobody revisited that starts dropping requests the first time traffic actually spikes. Or a WAF rule that fires on legitimate traffic nobody tested during implementation because testing WAF rules properly takes time nobody scheduled.
We configure the web delivery layer to surface problems at their actual source rather than masking them. Health checks that reflect real application readiness. Throttling limits backed by measured traffic data. WAF rules tested against realistic traffic patterns before going into blocking mode. See how this approach has delivered for our clients across our case studies.
AWS Web Services for Application Delivery
Six specialist capabilities covering the full web application delivery stack from load balancing to edge protection.
Application Load Balancer Architecture
We configure ALB listener rules to route traffic based on host header, path, query string, and HTTP method, so a single load balancer serves multiple applications or routes API and frontend traffic to different target groups. Following AWS’s ALB documentation, health checks are tuned with thresholds and intervals matched to real application startup times, not left at defaults that let a slow-starting container stay in an unhealthy target group for sixty seconds before it gets pulled from rotation.
AWS API Gateway for REST and HTTP APIs
HTTP API for low-latency, cost-efficient Lambda proxy and container integrations where the simpler feature set is sufficient. REST API where usage plans, API keys, request transformation, or request validation are needed. We configure throttling at both the stage and method level so a single endpoint’s traffic spike cannot consume the entire account’s quota, and set up CORS headers correctly for APIs consumed from browser-hosted frontends, since CORS misconfiguration is one of the most common API Gateway deployment issues we encounter during handover reviews.
AWS Certificate Manager and TLS Automation
ACM issues and auto-renews public TLS certificates for domains validated through DNS or email, eliminating the manual certificate renewal cycle entirely when attached to an ALB or CloudFront distribution. We configure DNS validation over email validation wherever the domain’s hosted zone is in Route 53, since DNS validation renews without any manual action and email validation depends on someone actually responding to a validation request before the certificate expires.
AWS WAF Web Application Firewall
WAF web ACLs attached to ALB or CloudFront with AWS Managed Rule Groups covering OWASP Top 10 vulnerabilities, rate-based rules that block IPs exceeding a request threshold within a rolling window, and Bot Control for distinguishing legitimate bot traffic from malicious scraping or credential stuffing attempts. Rules are deployed in count mode and validated against real traffic logs before switching to block mode, because a WAF rule blocking legitimate users is harder to diagnose than no WAF rule at all.
S3 and CloudFront for Static Web App Delivery
Single-page applications deployed to S3 with CloudFront in front, origin access control restricting bucket access to CloudFront only, and cache invalidation triggered automatically on each deployment so users receive updated assets without manual intervention or stale cache debugging. Separate CloudFront behaviours route API calls through to the ALB or API Gateway origin while serving static assets from the S3 origin within a single distribution.
AWS App Runner for Containerised Web Apps
App Runner deploys containerised web applications from ECR or source code without requiring ECS task definitions, cluster management, or load balancer configuration, making it the right choice when a client needs a public HTTPS endpoint for a containerised application without the operational overhead of running a full ECS or EKS cluster. Concurrency and auto-scaling settings configured against expected traffic so the service scales without manual intervention.
Our Traffic-Path-First Approach to AWS Web Services Delivery
We map the full traffic path for every web application before touching any configuration: how a request arrives at the domain, which certificate validates it, which load balancer rule it matches, which target group handles it, and which WAF rules evaluate it along the way. That map surfaces decisions that need to be made together rather than independently, because a WAF rule configured on the ALB and the same rule also on the CloudFront distribution in front of it means every request gets evaluated twice, and a false positive that only fires under load may not be visible during testing.
From that traffic path we configure each AWS web services component in sequence, validating behaviour at each stage before moving to the next. To scope your client’s web application delivery architecture, book a discovery call, and we return a preliminary scope within a week.
Capabilities We Bring to Every AWS Web Services Engagement
WebSocket support, sticky sessions, custom error pages, and deployment pipeline integration built into the delivery layer, not handled separately.
WebSocket and Long-Lived Connection Support
ALB WebSocket support for real-time web applications that need bidirectional communication without polling, configured with appropriate idle timeout values so connections don’t get silently dropped mid-session. API Gateway WebSocket APIs for serverless real-time applications where managing connections through Lambda is the right trade-off versus a persistent connection-aware compute layer.
Session Stickiness and Connection Affinity
ALB sticky sessions configured when a web application genuinely requires connection affinity to a specific target, alongside a clear recommendation against stickiness for applications that should be stateless, since stickiness that persists through a deployment sends returning users to the old version of the application longer than intended and complicates zero-downtime rollouts.
Custom Error Pages and Maintenance Responses
CloudFront custom error responses returning branded error pages from S3 for 4xx and 5xx origin responses, so a backend failure presents a controlled experience rather than a raw error code. ALB fixed-response actions returning a maintenance page with a specific status code during planned outages without requiring any origin changes.
Deployment Pipeline Integration
CloudFront cache invalidation integrated into the CI/CD pipeline so static web app deployments automatically invalidate changed assets without manual intervention. ALB weighted target group switching for gradual traffic shifts between application versions during deployments that need more control than a rolling update provides.
AWS Web Services Delivery Delivered Under Your Agency Brand
We work as the invisible engineering layer behind your agency’s AWS web application delivery. Our engineers configure load balancers, API gateways, WAF rules, certificates, and static hosting, and produce architecture documentation in your agency’s format. Your clients receive a delivery layer where the health checks reflect reality, the WAF rules have been validated against real traffic, and the TLS certificates renew automatically rather than expiring during a holiday nobody was monitoring.
Our white-label development model is built for agencies managing multiple clients’ AWS web applications. You scope confidently knowing the technical delivery is handled by engineers who’ve configured ALB routing rules and WAF rule validation before. For agencies running several concurrent web delivery projects, our agency partner programme provides priority access to our web engineering team, preferred project rates, and a dedicated account contact across all active client engagements.
Why AWS Web Services Delivery Problems Are Usually Hiding in the Configuration Defaults
The most common pattern: a WAF rule set deployed in block mode without a count-mode validation period first. Everything looks fine in staging because staging traffic is synthetic and doesn’t match the unusual but legitimate patterns real users generate. The first week in production, customer support starts receiving reports of intermittent errors from users whose requests happen to match a managed rule group pattern that was never intended to catch their specific browser or request format. Diagnosing which WAF rule is responsible requires CloudWatch logs and time nobody had budgeted.
The second pattern: an API Gateway stage-level throttling limit set to a default value that made sense at launch and never got revisited as traffic grew. The limit starts dropping requests the first time a genuine traffic spike hits, and the application returns 429 errors that look like a service failure to end users rather than a configuration limit that could be raised in five minutes once correctly identified. Our AWS development services practice validates every delivery layer default against real traffic data before a client goes to production, so configuration limits are set deliberately rather than inherited from a default nobody questioned.
Engagement Models for AWS Web Services Projects
Structured for agency delivery workflows. Scalable across your full client portfolio.
Web Delivery Architecture Sprint
A defined 2-to-4-week sprint covering the full web delivery stack: ALB configuration, API Gateway setup, ACM certificate provisioning, WAF rule validation, and static hosting or App Runner where applicable. Best for agencies whose clients need a properly configured delivery layer at the end of a fixed engagement.
Dedicated Web Delivery Engineer
A senior AWS web services engineer embedded in your client project, configuring load balancers, API gateways, and WAF rules, and validating delivery performance under realistic load. Operating in your project channels, producing documentation in your format. Available full-time or part-time depending on the current engagement phase.
Ongoing Delivery Layer Retainer
A monthly retainer for agencies managing multiple clients’ AWS web delivery configurations simultaneously. Covers WAF rule tuning as traffic patterns evolve, throttling limit reviews ahead of anticipated load events, certificate expiry monitoring, and ALB target group health reviews. Predictable monthly cost across your active client portfolio.
WAF and Security Review
A focused WAF and delivery security review for clients whose web application is already running on AWS but has never had its WAF rules, CORS configuration, or TLS settings properly audited. Covers count-mode log analysis, rule effectiveness testing, and certificate renewal configuration. Reach us via our contact page to discuss scope.
Our AWS Web Services Delivery Process
Six phases from traffic path mapping to production handover, with validation gates before each stage.
Phase 1 — Traffic Path Mapping
We map the full request path from domain to origin for every web application endpoint: DNS, certificate, CDN or load balancer, routing rules, and WAF evaluation order. This map surfaces configuration decisions that need to be made together and prevents duplicate enforcement at multiple layers that causes harder-to-debug production problems.
Phase 2 — Load Balancer and Routing Configuration
ALB listener rules and target groups configured for each application, with health check thresholds set against actual container or application startup times. Weighted routing between target groups configured where blue-green or canary deployment control is needed.
Phase 3 — TLS and Domain Configuration
ACM certificates provisioned with DNS validation for all domains and subdomains in scope, attached to the relevant ALB listeners and CloudFront distributions. HTTPS redirect rules configured on ALB HTTP listeners to ensure no plaintext traffic reaches the application.
Phase 4 — WAF Rule Deployment and Count-Mode Validation
WAF web ACL configured with selected managed rule groups in count mode, traffic routed through it, and CloudWatch logs analysed against real traffic patterns to identify false positives before switching any rule to block mode. Custom rate-based rules and any application-specific allow-list rules added based on count-mode findings.
Phase 5 — Static Hosting and CDN Configuration
S3 buckets configured with origin access control, CloudFront distributions set up with separate behaviours for static assets and API traffic, and cache invalidation integrated into the deployment pipeline. App Runner services provisioned where containerised hosting without cluster management is the right fit.
Phase 6 — Load Testing and Production Handover
Delivery layer behaviour validated under realistic load: health check thresholds confirmed functional, throttling limits verified against peak traffic estimates, WAF rules switched to block mode after count-mode validation, and architecture documentation delivered to your client’s team.
