CDN Dedicated Servers

Pick the role based on what you want to protect and where users are. For most teams, start with Origin + Shield, then add regional cache nodes.

• Origin: host the source assets your CDN pulls from. Use it for storage-heavy content.
• Shield: reduce cache-miss bursts hitting your origin. Put it near your origin.
• Regional cache: serve hot content closer to users in key regions.
• Private edge: deliver restricted content for internal or partner networks.

With dedicated CDN servers, you can run one role per node for clarity. You can also combine roles later, once traffic patterns are stable.

Choose based on peak throughput, not average usage. Peak drives outages and customer complaints.

Pick 10Gbps when:

• You serve mostly static pages and images
• Peak bursts stay moderate
• You run 1-2 regions first

Pick 25Gbps when:

• You ship large downloads or patches
• You serve streaming segments
• You run multiple regions with heavy cross-fill

On CDN Servers, you also plan headroom for cache misses. Miss storms can double origin pull rates fast.

Pick the billing model that matches your variance. Variance is what breaks budgets.

Choose metered when:

• Traffic is steady
• You can forecast TB per month
• You want a tighter monthly target

Choose unmetered when:

• Launches create spikes
• Streaming peaks are unpredictable
• Patch days pull huge bursts

Many teams start metered, then switch once growth stabilizes. With CDN Dedicated Servers, keep your routing and cache rules the same. Only the bandwidth model changes.

Start with the minimum that improves real latency. More regions add ops work.

A practical starting layout:

• USA: one region near your largest user cluster
• UK/EU: one region for Europe traffic
• India: one region for South Asia traffic

Then expand based on:

• Top 3 countries by requests
• Cache hit ratio by region
• User-reported buffering and slow downloads

With RedSwitches CDN Servers, you can add nodes per region as demand grows. Keep each region consistent in config and logging.

Use the simplest routing that meets your uptime goals. Complexity adds failure modes.

• GeoDNS fits most early-stage CDNs. You map regions to the nearest PoPs.
• GSLB fits teams that need health-based steering and weighted routing.
• Anycast fits large delivery networks that want latency wins at scale.

RedSwitches provides the dedicated CDN servers. You choose the DNS or traffic steering layer. With Dedicated Servers for CDN, you control the nodes. Your DNS or traffic steering layer decides where users land. Start with GeoDNS and add health checks early.

Pick based on how fast you need results and how complex your rules are.

• NGINX cache: best for fast deployment and simple caching. Good first choice.
• Varnish: best for advanced HTTP caching logic and fine rule control.
• Apache Traffic Server: strong for large-scale caching and high-throughput setups.
• Hybrid: common for mature stacks. Use NGINX for TLS termination, then Varnish or ATS behind it.

On CDN Dedicated Servers, start simple and measure hit ratio. Add complexity only when you see a clear gain.

Use versioning first. Purge only when you must.

Best practice flow:

• Version assets (hash in filename). Then you avoid purges for most releases.
• Use targeted purges for specific paths, not wildcards.
• Use soft purge when supported, so you serve stale briefly while revalidating.
• Batch purge requests to avoid thundering herds.

On RedSwitches Dedicated Servers for CDN, you can run purge orchestration from your deploy pipeline. Keep purge events logged for audits and rollback.

Use TTLs that match the change frequency. Short TTLs everywhere waste cache value.

A clean starting policy:

• Versioned assets: long TTL, treat as immutable.
• HTML: short TTL with revalidation. HTML changes often.
• APIs: micro-cache only for safe endpoints, very short TTL.
• Large downloads: long TTL with versioning, plus resumable delivery support.

This approach improves cache hit ratio while keeping content fresh. It also keeps CDN Servers from hammering your origin on every request.

Terminate TLS on your cache nodes and tune for modern clients. TLS tuning often cuts CPU waste.

Use this baseline:

• Enable TLS 1.3 and strong TLS 1.2 ciphers
• Turn on session resumption
• Use OCSP stapling where possible
• Prefer ECDSA certs if your client mix supports it
• Keep connections warm with keep-alives and HTTP/2

On CDN Dedicated Servers, TLS load rises fast at peak. Plan CPU headroom for handshake bursts and bot traffic.

Treat network DDoS protection as your first layer, not your full security plan.

RedSwitches includes DDoS protection for your delivery endpoints. That helps against volumetric floods and noisy traffic patterns. You still secure:

• Your OS and SSH access
• Your cache software config and exposed ports
• Rate limits for abusive paths
• An application-layer firewall if you serve dynamic endpoints

For Managed CDN Dedicated Servers, many teams want help with baseline hardening and monitoring. You still own application logic and cache rules.

Block public access to the origin. Force all traffic through your cache hierarchy.

Do this:

• Allow origin access only from your shield node IPs
• Use firewall rules at the origin and upstream network controls
• Add origin authentication headers or tokens
• Separate admin access from delivery access

This design prevents direct-to-origin bypass. It also reduces the attack surface. It makes your Dedicated Servers for CDN behave like a real delivery fabric, not just extra servers.

Harden before you put the node into routing. Most CDN breaches start with weak access control.

Day-one checklist:

• SSH keys only, no passwords
• Close all ports except required delivery ports
• Apply OS updates, enable unattended security patches
• Set firewall allowlists for admin paths
• Add basic rate limits and request size limits
• Enable time sync and log rotation
• Set up monitoring for CPU, disk, bandwidth, and cache hit ratio

On RedSwitches CDN Servers, you also keep recovery access available. Use it as an emergency tool, not a daily workflow.

Plan migration like a release, not like a server move. You want a clean rollback path.

A safe migration sequence:

• Deploy new nodes and apply your standard config
• Validate headers, cache keys, and purge behavior in staging
• Warm cache with top paths and critical assets
• Cut traffic with a small percentage first
• Increase gradually while watching the hit ratio and origin load
• Keep the old path ready for rollback for at least one release cycle

With CDN Dedicated Servers, you can run parallel stacks during cutover. That reduces risk and keeps customer experience steady.

Act fast and isolate. A bad cache rule spreads issues quickly.

Incident response steps:

• Drain traffic from the node at the routing layer
• Disable the risky rule set and reload the service
• Clear only the affected cache keys when possible
• Verify origin health and shield behavior
• Reintroduce the node slowly after metrics stabilize

Use configuration versioning for cache rules. Treat config changes like code changes. On Dedicated Servers for CDN, recovery speed depends on discipline, not luck.

Log with intent. Full logs on every request can crush disks and CPUs.

A practical approach:

• Keep access logs, but rotate aggressively
• Separate cache logs from system logs
• Forward logs asynchronously to your SIEM or analytics stack
• Sample high-volume endpoints if needed
• Track the metrics that matter: hit ratio, 4xx/5xx rates, origin fetches, egress

On CDN Dedicated Servers, logging should never compete with delivery. Protect disk I/O and keep cache serving priority first.
