Is sticky session good?
Sticky sessions can make it more complicated to have high availability and scalability. For the former, consider the case where one server goes down – all sessions on that server will also go down and you will have to write code to fail them over to the other server.
Why do we need sticky session?
However, you can use the sticky session feature (also known as session affinity) to enable the load balancer to bind a user’s session to a specific target. This ensures that all requests from the user during the session are sent to the same target.
What can sticky sessions affect?
Since requests for a user are always routed to the same machine that first served the request for that session, sticky sessions can cause uneven load distribution across servers.
How do I get rid of sticky sessions?
An application can get rid of sticky sessions by using an external service for keeping its state. See the example below. Each server performs actions, saving the process of each task or request to a shareable resource, like MySQL or Redis, making it available to all other servers of our infrastructure.
What are the issues with sticky sessions?
Is sticky session load balancing?
Enabling sticky sessions on a load balancer
- Ensure that both web servers have the same machine key.
- Ensure that the websites have been precompiled before deployment. For serialisation of objects by ASP.NET State Service.
- Ensure that the application path on the iis metabase is identical on both web servers.
How do you stop a sticky session?
To avoid this kind of problem, there are several ways:
- Use a clustered web application server where the session are available for all the servers.
- Sharing user’s session information in a database or a file system on application servers.
- Use IP level information to maintain affinity between a user and a server.
Is Kubernetes a load balancer?
In other words, Kubernetes services are themselves the crudest form of load balancing traffic. In Kubernetes the most basic type of load balancing is load distribution. Kubernetes uses two methods of load distribution. Both of them are easy to implement at the dispatch level and operate through the kube-proxy feature.
What is a headless service?
What is a Headless Service? When there is no need of load balancing or single-service IP addresses. We create a headless service which is used for creating a service grouping.
