There is a caching server called Varnish which retrieves data from Amazon S3 upon request, stores it temporarily, and then delivers it to the client. However, there is an issue with the limited bandwidth of 1Gbit, as the channel gets completely congested during peak loads that last for four hours. The server's performance is still sufficient, but it is unable to handle the data transfer efficiently. On average, about 4.5TB of data is transferred per day, resulting in over 100TB in a month.

One possible solution would be to add another gigabit port to overcome the bandwidth limitation temporarily, but this might not be a long-term fix. As the demand increases, more caching servers would need to be added, accompanied by a load balancer that directs requests to the same server for a specific URL, preventing duplication of cached objects.

Now, let's address the questions:

1. With the addition of multiple caching servers, the load balancer would require a total bandwidth equal to the combined capacity of all the caching servers. However, if adding more ports to the load balancer is not feasible, an alternative solution could be to introduce additional load balancers and employ Round robin DNS to distribute the incoming traffic evenly among them.

2. Standard approaches to solving such problems involve scaling infrastructure by adding more servers and load balancers, implementing caching mechanisms, enhancing network capacity, and optimizing data transfer protocols. Additionally, analyzing and optimizing the application architecture can also help alleviate bottlenecks and improve performance.

3. For hosting companies that can assist with resolving this problem, you may consider exploring the services offered by reliable providers in both the American and European markets. Some prominent options include Amazon Web Services (AWS), Google Cloud Platform (GCP), Microsoft Azure, and DigitalOcean. These providers offer comprehensive solutions for managing and scaling infrastructure, ensuring efficient data delivery, and optimizing network performance.


Can we not request a provider to aggregate LACP channels?

The load balancer lacks the capability to handle all traffic on its own. However, it can redirect the request to one of the caching servers for processing.

 aggregating LACP channels can greatly improve network performance and reliability by combining multiple physical connections into one logical link. This allows for increased bandwidth and redundancy. Additionally, offloading traffic to caching servers can help optimize resource allocation and improve overall system performance.


Can we not distribute the content across multiple servers?

Consider LVS as a solution. According to the description provided on, options like IP Tunneling and Direct Routing address the issue of limited bandwidth on the load balancer by utilizing their own channels to provide responses.

While I haven't personally encountered it in practice, exploring these options may prove beneficial in optimizing resource allocation and improving overall performance.

Dividing the content across multiple servers can help alleviate the load on individual servers, improve scalability, and enhance fault tolerance. By utilizing load balancing techniques like LVS, organizations can ensure efficient distribution of workload among servers, resulting in enhanced performance and reliability.


If your load balancer is trustworthy,
consider installing ADX 1016,
and you can rest easy knowing that your traffic will be efficiently managed.

As for the nature of the traffic, based on my understanding, you are referring to static traffic.

Implementing a reliable load balancer like ADX 1016 can significantly enhance the performance and reliability of your network infrastructure. It ensures that incoming traffic is evenly distributed across multiple servers, avoiding overloading and maximizing resource utilization. This not only improves the user experience but also provides a level of peace of mind, knowing that your system is effectively handling the workload.
