We use Kubernetes in a big bare metal cluster, and we are here at the Red Hat summit to talk about a migration directly to OpenShift to create an hybrid infrastructure that can help us to achieve a more resilient services for our clients, actually we got a lot of problem with the limits of k8s, especially with the calico service middleware, when our transactions are with high demand calico gets crazy and reset connections, for example, also we got and issue with the middleware limits, we are running 160 pods for worker, and we got 6 mega hardware workers, that we cant use it fully hardware for the middleware limits, thats the reason we are leaving k8s and working in a migration to OpenShift en AWS

Kubernetes is the answer but, what was the question?
I deploy & manage telco workloads on top of Kubernetes. These are called CNFs (Containerized network functions) which are legacy telco applications converted into K8s objects & connected via a networking & storage solution of your choice, managed by K8s. Just like every other industry, Telcos are no exception converting all their legacy applications sitting on proprietary hardware & boxes to COTS hardware & software architectures adapted toward cloud technologies. Kubernetes helps us to manage the CNFs efficiently & gives a better uptime as compared to VM-based architecture. I see the scope of flexibility & easy scaling in K8s as compared to any other technology.

Currently we are using Kubernetes in our project to orchestrate the containers. We are using it for our banking client where some point of time user transection get increased while they try to use banking applications. whenever load get increase Kubernetes spin new pods in the cluster using replicaset to handle the load of user transections.
On the foundation, Kubernetes manages containers such as docker containers or from other technology and it helps you manage containerization applications that are made of hundreds of containers in different environments such as physical machines, virtual machines or cloud machines, or even hybrid deployment environments. As in my specific scenario, we install a Kubernetes cluster on CentOS 8 with one master node and two worker nodes for orchestration of our existing applications containers.
We have moved almost all the stateless services to Kubernetes so managing the umpty number of services can be so easy. Kubernetes helps us in scaling the services up or down based on business needs. It helps us in upgrading the bunch of clusters with zero to minimal downtime based on the applications. We also moved stateful database services (mostly NoSQL) to Kubernetes to manage a single place and to keep the cost down.
Kubernetes was used in my organization by a specific department. The business problem it attempted to address was resource allocation and scheduling. Creating and tearing down containers at will dependant on resource demand. These resources provided API services to the front-end website.

Great way to deploy/manage your servers.
I am working in a company that is currently working on moving everything to the cloud. We want to leverage as many as cloud managed services as we can. Kubernetes came to our sight when we thinking of containerizing our on-premises servers for fast and easy deployment to cloud. We are still experimenting with Kubernetes but based on what we've got now, it works perfectly for our department.

Kubernetes, a good cluster management system to place bets on
Kubernetes is currently used as an experimental product for building and managing Machine Learning pipelines (ML) at LinkedIn. It is currently used by very few teams to access GPU clusters. Kubernetes makes it easy to deploy training and monitoring workloads on clusters really simple with a robust CLI. It has a very small learning curve as is mainly driven by config files.

Kubernetes, managing the future
We use Kubernetes at a department level and across the whole organization. At a department level, we use Kubernetes to manage our developer environments. These environments are made up of 30 containers containing compilers, single sign-on managers, and various other linting tools. We selected Kubernetes to manage these containers because it's quick to deploy and immensely customizable. Across the organization, we use Kubernetes to manage our customer environments. These environments are made up of ~8 containers running various managed web services. Kubernetes was selected for this because it is open source, scalable, and reliable. This allows us to cost-effectively deploy a solution and be confident that it will perform as needed.
Kubernetes has become the microservice container orchestration platform of choice. All our software deployed into Kubernetes - including public websites.

Kubernetes is "the" tool for Docker orchestration
We as an organization have very diverse hardware infrastructure. We have our own data centers and multiple cloud providers. The technologies we use are also again very diverse, we use VMs, containers as well as server-less technologies. When it comes to container technologies we are using Docker and orchestrate it with Kubernetes. In most of the cases, each Business unit have their own Kubernetes clusters for application hosting, and categorize it separately for preproduction and production environments.

Worth the Learning Curve
Kubernetes has massively simplified and sped up the management of microservices deployed within my team. If we need to spin up a new service, even if it doesn't relate to the other services in the cluster, we can simply deploy the docker container to the cluster, complete with service discovery, configuration management, autoscale and fault tolerance. This is invaluable.

Poor man's review
- Whole organization.
- Used as a PaaS.
- Used to deploy mostly stateless and cloud-ready apps.
- Solves the problem of immutable infrastructure. No need for Chef, Puppet or Ansible.
- Low learning curve for users.
- Apps start on failure, can auto scale; burst into cloud;
- Infra is cloud agnostic; works in an in-house datacenter too. Gives leverage to mangement for negotiations with cloud providers

Easiest containerized deploy, bar none!
It is being used across many departments, with more being added every day. My team was one of the first teams to use Kubernetes 8 for our microservice deployments. It addresses the problem of HDHA applications, agile development, rolling deployments with no downtime. We are also utilizing its service discovery with spring boot admin to provide node level details for all nodes in the cluster.

The best way to run your containers
For managing containers across a cluster of servers, I won't use anything but Kubernetes. It makes scheduling containers extremely easy. Bundling applications that we develop into Docker images has made deployment a really simple process for us. It's made it so that we don't have to think too much about the clash that comes of running multiple applications on the same set of hosts. It's also helped our engineers to write idempotent applications better because we scale up and down often.
