How was C10K problem solved?

C10K Problem – So Last Decade. A decade ago engineers tackled the C10K scalability problems that prevented servers from handling more than 10,000 concurrent connections. This problem was solved by fixing OS kernels and moving away from threaded servers like Apache to event-driven servers like Nginx and Node.

What is ck10 problem?

The C10k problem is the problem of optimizing network sockets to handle a large number of clients at the same time. The problem of socket server optimisation has been studied because a number of factors must be considered to allow a web server to support many clients.

How many clients does a server have?

On the TCP level the tuple (source ip, source port, destination ip, destination port) must be unique for each simultaneous connection. That means a single client cannot open more than 65535 simultaneous connections to a single server. But a server can (theoretically) serve 65535 simultaneous connections per client.

How many concurrent connections can Nginx handle?

Each NGINX worker can handle a maximum of 512 concurrent connections. In newer versions, NGINX supports up to 1024 concurrent connections, by default. However, most systems can handle more. Nevertheless, this configuration is sufficient for most websites.

What is NGINX and how it works?

NGINX is a web server that also acts as an email proxy, reverse proxy, and load balancer. The software’s structure is asynchronous and event-driven; which enables the processing of many requests at the same time. NGINX is highly scalable as well, meaning that its service grows along with its clients’ traffic.

Does Kubernetes use NGINX?

The NGINX Ingress Controller for Kubernetes combines the benefits of using the Kubernetes control plane to manage load‑balancing configuration with the performance, reliability, and advanced features of NGINX and NGINX Plus.

What is the first step in the problem solving process?

The first phase of problem-solving requires thought and analysis. Problem identification may sound clear, but it actually can be a difficult task. So you should spend some time to define the problem and know people’s different views on the issue. Understand everyone’s interests. You should not skip this critical step in the problem-solving process.

How do you solve problems effectively?

Keep in mind that effective problem solving does take some time and attention. You have to always be ready to hit the brakes and slow down. A problem is like a bump road. Take it right and you’ll find yourself in good shape for the straightaway that follows. Take it too fast and you may not be in as good shape.

What is the A3 methodology for problem-solving?

Instead of fighting only the symptoms, you need to dig deeper and discover the root cause. By doing so, you will be able to protect the work process from recurring problems. This is where the A3 methodology comes into play. Implementing an A3 problem-solving tool is a bright example of how problems should be treated to be eliminated efficiently.

How to solve a problem with countermeasures?

Once you are familiar with the root cause, you may start offering solutions. From here, you can go back to the initial goal and add more details. In all cases, the countermeasures should lead to a clear understanding of how the initial goal will be achieved.
