CDN expertise — from Switzerland

Frequently Asked Questions

What CDN consulting services does VSHN offer?

VSHN offers vendor-neutral CDN consulting covering architecture design, provider evaluation, performance optimisation, security configuration, and cost analysis. We work with all major CDN providers including Cloudflare, Akamai, Fastly, KeyCDN, AWS CloudFront, Azure CDN, Google Cloud CDN, and F5 Distributed Cloud CDN. Engagements range from a one-day architecture review to multi-week implementation projects. We also offer ongoing advisory retainers for organisations that need continuous CDN optimisation support.

Which CDN providers do you recommend?

We do not recommend a single provider for every use case. Our evaluations consider your traffic volume, geographic distribution, performance requirements, security needs, and budget. For Swiss organisations, KeyCDN is particularly interesting as a Swiss-based provider. Cloudflare offers excellent DDoS protection and a generous free tier. Akamai and Fastly excel for enterprise-grade delivery with fine-grained configuration. AWS CloudFront integrates tightly with the AWS ecosystem. We help you find the right fit.

What is a multi-CDN architecture?

A multi-CDN architecture distributes your content across two or more CDN providers simultaneously. Traffic is routed using DNS-based load balancing, real-user measurement steering, or application-level logic. This approach eliminates single-provider outages as a risk, reduces latency by choosing the fastest provider per region, and gives you commercial flexibility. VSHN designs multi-CDN setups using combinations of Cloudflare, Fastly, Akamai, and cloud-native CDNs from AWS, Azure, and Google Cloud.

Can you help with CDN security configuration?

Yes. CDN security is a core part of our consulting practice. We configure DDoS mitigation, Web Application Firewalls, bot management, TLS certificate management, and rate limiting. Providers like Cloudflare, Akamai, and Fastly offer sophisticated security features that require careful tuning to avoid blocking legitimate traffic while stopping attacks. We review your current configuration, identify gaps, and implement best-practice security policies tailored to your application and threat model.

What SLA does VSHN guarantee for CDN consulting engagements?

VSHN consulting engagements follow our standard service level agreements. For ongoing advisory retainers, we target 99.9% availability for our support channels with guaranteed response times. The CDN providers themselves offer their own SLAs — for example, most enterprise CDN contracts guarantee 99.99% uptime with over 500 GB of included traffic. We help you evaluate and negotiate provider SLAs as part of our vendor selection consulting, ensuring your CDN infrastructure meets your business availability targets.

Does VSHN have cloud provider partnerships relevant to CDN?

Yes. VSHN is a Swiss Select Partner for major cloud platforms, which gives us deep technical access and commercial benefits for our customers. This partnership status covers AWS, Azure, and Google Cloud — all of which offer integrated CDN services (CloudFront, Azure CDN, and Cloud CDN respectively). Our partner status means we can provide authoritative guidance on cloud-native CDN solutions and help you leverage committed-use discounts that reduce your overall CDN costs.

How does Swiss data residency affect CDN configuration?

CDN edge nodes cache your content in data centres around the world, which can create data residency complications for organisations subject to Swiss data protection law or GDPR. We help you configure geo-restrictions to control where content is cached, evaluate which CDN providers have Swiss points of presence, and design architectures that satisfy compliance requirements without degrading performance. Swiss-based KeyCDN and providers with Zurich edge nodes like Cloudflare and Fastly are often part of the solution.

What does a CDN performance optimisation engagement involve?

We start by measuring your current performance using real-user monitoring and synthetic tests from multiple Swiss and European locations. We then analyse cache hit ratios, origin response times, TTL configurations, and content purging workflows. Based on the data, we design an optimised caching strategy, configure origin shielding, tune HTTP headers, and implement image and asset optimisation. Typical engagements deliver a 40-60% improvement in page load times as measured by Core Web Vitals and Lighthouse scores.

How do I get started with VSHN CDN consulting?

Contact us using the form below or send an email to info@vshn.ch. Describe your current CDN setup or requirements — whether you need a new CDN evaluation, performance optimisation of an existing setup, a multi-CDN migration, or a security review. We provide a free initial consultation to understand your needs and a written scope with CHF cost estimate within one business day. There is no commitment at the scoping stage. Engagements typically start within one to two weeks of agreement.

Can VSHN help migrate between CDN providers?

Yes. CDN migration requires careful planning to avoid downtime and performance regressions. We handle DNS cutover planning, SSL certificate provisioning on the new provider, cache warming strategies, and parallel running periods where both old and new CDNs serve traffic. We have migrated customers between Cloudflare, Akamai, Fastly, and cloud-native CDNs on AWS and Azure. Our migration projects include rollback plans and real-time monitoring to ensure zero-downtime transitions.
