In essence, a closure is a block of code that can be executed at a later time, but which maintains the environment in which it was first created - i.e. it can still use the local variables, etc of the method which created it, even after that method has finished executing.

Here's an example using an anonymous method: using System; class Test { static void Main() { Action action = CreateAction(); action(); action(); } static Action CreateAction() { int counter = 0; return delegate { // Yes, it could be done in one statement; // but it is clearer like this. counter++; Console.WriteLine("counter={0}", counter);

So we can say that Kubernetes help us manage the containerized application, We can use Kubernetes on a different type of environments let it be a physical server, virtual machines or cloud. What Problem Does It Solve : The rise of microservice architecture has increased the use of container technologies. nowadays a complex enterprise application can have thousands of containers. managing those containers using scripts or self-made tools is very tough and error-prone. Kubernetes like container orchestration tools solve this problem. A container orchestration tool offers the following features High Availability or no downtime Scalability or high performance Disaster recovery Basic Architectures: Kubernetes cluster is made of at least one master node and connected to it a couple of worker nodes .
