Why is not using a proxy more expensive than it seems

Working with data on the internet is built around the movement of requests from your device to numerous services and websites. Many teams believe they can operate without proxies by sending requests directly to data sources. However, in most cases proxies are actually necessary. They become an intermediate layer between you and the external world, improving security and protecting your data. It is important to understand where and how to use proxies correctly, since they not only help save resources but also add stability and manageability to the entire infrastructure.

What role proxies play in working with internet infrastructure

• Proxies can be viewed as a connecting link between your application and external services. They provide stable access to data through caching, and if the required response is already stored in the proxy’s memory, the system returns it without contacting the source. This reduces overall traffic and speeds up response time. Proxies also help distribute load so that a single point is not overloaded and bottlenecks are avoided. This increases the overall throughput of the system and reduces the risk of downtime.
• During large-scale operations, such as data collection or monitoring, proxies make it possible to process a large number of requests simultaneously and reuse open sessions. Reusing already established connections simplifies scaling.
• Properly configured proxies help reduce response time and increase data access speed by being located closer to users and sources, as well as through caching and route optimization.

Main consequences of not using proxies

Without proxies, your traffic goes directly to data sources and services. Without a centralized intermediate layer, you lose important tools for control and optimization.

• Performance suffers due to the absence of caching and response reuse. Frequent requests for the same data occur without a fast local response source, so the service has to respond again every time. This adds delays and increases network load.
• During sudden traffic spikes, all requests go through a single internet exit point, which quickly turns a static scheme into a bottleneck. Services start limiting traffic, delays appear, and sometimes even blocks occur because the identifiable stream of addresses becomes too noticeable or unacceptable for service providers.
• The need for additional resources increases. To support growing workloads without proxies, the infrastructure must be expanded — more servers, more bandwidth, more logging and monitoring. This leads not only to higher costs for hardware and communication channels but also to additional labor required for configuration, updates, and maintenance of complex setups.
• Without proxies it becomes difficult to separate workloads between teams because all traffic exits through the same channel. As a result, environments must be duplicated or teams must accept the risk of unstable operation caused by queues and access conflicts.
• Opportunities for analysis and control become limited. There is no unified view of traffic, no centralized management of cache TTL, data refresh policies, or service availability monitoring — teams constantly have to improvise depending on a specific source and moment.

Indirect and “invisible” losses

Errors in automated processes

If access to data is unstable or delayed, scheduled tasks may miss deadlines, retry operations, and get stuck in queues. These failures accumulate, overload process orchestration, and reduce the overall reliability of the entire system.

Accuracy of analytics and marketing tools decreases

Data is collected with delays, reports diverge from the real situation, and therefore audience segmentation, conversion attribution, and retargeting become less accurate.

Reputational risks appear

User experience becomes sensitive to delays and service instability, affecting customer trust and brand perception. In the long term, such “invisible” problems can significantly reduce competitiveness: customers are lost, engagement metrics drop, and support costs increase.

Why using proxies saves resources

Load distribution and faster performance

Proxies make it possible to distribute requests evenly between different sources and network branches, while also caching frequently requested data. Some requests are returned to the client without contacting distant servers. As a result, latency for users decreases and the total traffic volume to external services is reduced, saving resources and accelerating the entire infrastructure.

Centralized management and monitoring

When traffic passes through a unified proxy layer, the team gains a single place to configure access policies, caching rules, and limits on the number of parallel requests. This simplifies monitoring, speeds up diagnostics, and reduces the risk of inconsistencies between individual services. A single control point helps maintain data quality and service availability without additional workarounds across different parts of the network.

Scalability

As the volume of data and the number of requests grow, proxies can be scaled independently of the main infrastructure layer. By adding a new proxy node, there is no need to redesign the architecture of data sources. This provides flexibility for expanding capacity and gradually entering new markets or audience segments.

Reduced downtime risks

Proxies create a buffer between your application and external sources: if a source experiences temporary delays or blocks, the proxy can continue serving clients using cached data and retry mechanisms within its own infrastructure. Services become more resilient to external fluctuations.

How proxy implementation pays off in practice

Investments in proxies are compensated by reducing traffic and computing costs, as well as by saving team time spent on maintaining and developing processes.

For example, the proxy service Belurk processes thousands of requests per day. Without proxies, these requests translate into significant expenses for traffic and computing resources on source systems. After implementing proxies, part of the requests to external services is cached or processed at the edge of the network, and the actual consumption of external resources decreases by approximately 45–50%.

A well-designed proxy architecture reduces traffic to external services, lowers the load on sources and teams, accelerates response times, and decreases downtime. From request to request, these improvements accumulate into consistent savings and more predictable infrastructure performance.
