How To Choose Hong Kong 100g High-defense Server Bandwidth Configuration Based On Business Traffic

this article teaches you how to properly allocate bandwidth for high-defense servers deployed in hong kong from the dimensions of business traffic characteristics, concurrency and peak calculations, computer room and operator selection, protection strategies and billing models, taking into account cost, stability and anti-ddos capabilities, so as to facilitate quick decision-making and procurement.

how much bandwidth is enough: how to estimate it by business type?

different services have widely varying requirements for bandwidth configuration . static content (pictures, file downloads) is mainly estimated based on peak bandwidth and concurrent downloads; streaming media and live broadcasts are mainly estimated based on the code rate multiplied by the number of concurrencies; api and e-commerce focus on the number of concurrent connections and response time. generally, the normal peak traffic is estimated first, and then 1.5-3 times is set aside to allow for redundancy to cope with instantaneous surges and cleaning overhead. for scenarios where hong kong 100g high-defense servers are used, the baseline bandwidth is often set to 30%–50% of the expected peak value, and the rest is guaranteed through the upstream backbone or cleaning and forwarding.

which peak metric is most important: bandwidth, pps or concurrency?

it is easy to misjudge by looking at numbers alone. bandwidth (mbps/gbps) determines throughput; pps (packets/second) affects the processing capability of network equipment; the number of concurrent connections determines server-side concurrent processing and database pressure. ddos attacks often package and traffic both ends at the same time. therefore, when purchasing, you must confirm the pps processing capability and connection table size of the high-defense server under the 100g port, as well as the cleaning capacity and response delay provided.

how to calculate concurrency and bandwidth requirements? can you give me the formula?

a simple formula can be used to make a preliminary estimate: bandwidth (mbps) ≈ (average page size (kb) × number of concurrent requests per second)/128. example: the page size is 300kb, and when the concurrency is 1000, the bandwidth ≈ (300×1000)/128 ≈ 2344mbps ≈ 2.3gbps. streaming media is calculated based on the code rate × the number of concurrencies, for example, 2mbps code rate × 1000 concurrencies = 2000mbps ≈ 2gbps. don’t forget to add tls, retransmissions and header overhead, as well as redundancy to resist attacks.

where can i deploy it to get better delay and protection effects? which computer room in hong kong is more suitable?

as an asia-pacific exchange hub, hong kong is directly connected to the mainland and southeast asia networks, and is suitable for businesses with both mainland and international traffic. when choosing a computer room, consider the backbone bandwidth (direct connection to mainland china, cn2 line), operator resources (telecom/china unicom/china mobile internet quality in hong kong), and the scale of the local cleaning center. if the target users are mainly in mainland china, they can give priority to hong kong computer rooms with good direct connections to domestic operators, and use hong kong's 100g high-defense servers to achieve low latency and high availability.

why choose 100g high defense instead of smaller caliber? what are the advantages and cost considerations?

the advantage of the 100g port is that it can respond to large-scale bandwidth-based attacks, facilitate large-scale traffic cleaning and diversion, and reduce the paralysis of the entire machine caused by excess traffic. however, high costs and excess resources will lead to waste of expenses. small and medium-sized businesses can use the 10g/40g+cdn+cloud cleaning combination. for high-value targets such as finance, games, and videos, 100g provides a higher security margin and operation and maintenance flexibility, which is a guarantee of protection capabilities and business continuity.

how to choose protection strategy and elastic bandwidth to reduce risks and costs?

it is recommended to adopt the "baseline + on-demand elasticity" strategy: the baseline bandwidth meets the daily peak value, and elastic cleaning or upstream cleaning (billed by hour or traffic) is automatically enabled after the threshold is triggered. configure intelligent traffic identification, whitelist, speed limit and traffic mirroring to avoid accidentally injuring normal users. the cleaning trigger conditions, sla, cleaning duration and recovery process need to be clearly specified in the contract to ensure that the service is available and the cost is controllable during the attack.

which purchase plan is more suitable for enterprises or individuals: yearly and monthly subscription or billing based on traffic?

the annual and monthly subscription is suitable for enterprises with stable traffic and sufficient budgets. the price is more cost-effective and exclusive resources can be reserved; the traffic/hour is suitable for scenarios with large traffic fluctuations or short-term activities, and can be expanded on demand during the attack period. for enterprises pursuing the lowest latency and maximum control, it is recommended to choose the hong kong high-defense hybrid solution with local cleaning and cross-machine room redundancy, while retaining on-demand flexibility to deal with extreme traffic events.
