Effective mitigation starts before traffic reaches the server, with edge filtering, traffic analysis and an operation that is ready for real incidents. For anyone hosting communities in Brazil, the right choice cuts downtime during peak hours. 5 min Read guide](https://streethosting.com.br/en/guides/infrastructure/anti-ddos-game-server-brazil) [Infrastructure Intermediate Single thread vs multi thread CPU: what matters on a server A game server can lag with the CPU at 25% while a database puts every core it can find to work. Learn where that difference comes from, how to tell which side your application is on, and what kind of vCPU to buy. 11 min Read guide](https://streethosting.com.br/en/guides/infrastructure/single-thread-vs-multi-thread-cpu) [Infrastructure Intermediate Layer 3 vs layer 4 vs layer 7 DDoS: what's the difference? A layer 3 DDoS fills the pipe, a layer 4 DDoS fills up connection tables, and a layer 7 DDoS makes the application work until it falls over.

Each one ruins the experience in a different way, and knowing which one is bad is what decides the fix. 9 min Read guide](https://streethosting.com.br/en/guides/infrastructure/ping-vs-jitter-vs-packet-loss) [Infrastructure Intermediate Protect a web application from attacks: defense in layers No single tool protects a web application on its own.

UDP delivers what it can without waiting for anyone. Understanding that trade explains why games and voice use UDP, why APIs use TCP and why opening lots of ports in the firewall does not work. 9 min Read guide](https://streethosting.com.br/en/guides/infrastructure/tcp-vs-udp) [Infrastructure Intermediate How to use traceroute to find routing problems Traceroute lists every router between you and the server and how long each one takes to answer. Read the right way, it shows whether the delay starts at your home, at your ISP, between networks or at the destination. 8 min Read guide](https://streethosting.com.br/en/guides/infrastructure/how-to-use-traceroute) [Infrastructure Intermediate How to use MTR to diagnose network problems MTR combines traceroute and ping and shows, hop by hop, where latency climbs and where packets get lost. The trick is knowing which loss is real and which is just a router rationing its replies. 8 min Read guide](https://streethosting.com.br/en/guides/infrastructure/how-to-use-mtr) [Infrastructure Intermediate Dedicated server checklist: what to ask before you sign Almost every dedicated server headache comes from something nobody asked before signing.
