Telcos have found Kubernetes to be a valuable tool for deploying and managing their legacy telco applications. By converting these applications into Kubernetes objects, telcos have been able to improve uptime and scalability. The simplicity and speed of Kubernetes make it ideal for managing microservices, enabling easy deployment, service discovery, configuration management, autoscaling, and fault tolerance. This has been particularly useful for organizations like LinkedIn, which has used Kubernetes as an experimental product for building and managing Machine Learning pipelines and accessing GPU clusters. Additionally, Kubernetes is widely adopted as a PaaS solution throughout organizations, solving the problem of immutable infrastructure and providing a low learning curve for users. It offers scalability and reliability, making it suitable for managing developer and customer environments at both departmental and organizational levels. Moreover, Kubernetes excels in orchestration across diverse hardware infrastructures, including data centers and multiple cloud providers. It effectively manages containerization applications consisting of hundreds of containers deployed on physical machines, virtual machines, or cloud machines. This addresses resource allocation and scheduling challenges by creating and tearing down containers based on resource demand. Furthermore, Kubernetes serves as a powerful tool for containerizing on-premises servers for seamless deployment to the cloud. Its versatility and standard deployment through Helm have made it the preferred microservice container orchestration platform for deploying web-based applications. Overall, Kubernetes offers a wide range of use cases that enhance the deployment, management, and scalability of various applications in different environments.

(1-5 of 5)Kubernetes is the answer but, what was the question?
- Makes sure that the workload remains UP & running by maintaining the desired state.
- Gives a lot of flexibility in choosing the networking, storage, monitoring, etc solutions of your choice.
- The biggest advantage is to upgrade the application with a new version without any downtime.
- Portability of the code is possible up to a great extent.
- Flexibility gives birth to complexity & therefore designing an application on K8s is also complex.
- Writing Yaml manifests manually & then validating them for errors is a pain that should be worked upon with a solution that can write YAMLs & Helm charts in the background with the user designing the application on a GUI-based sketch. Just like they do in OpenStack.
- The overall approach of operations should be shifted from CLI to GUI-based for ease of use.
- Due to a lot of objects & new concepts, the learning curve is really flat i.e. slow.
- Adding GUI-based operations like finding the exact point causing latency OR showing the POD consuming the highest CPU/RAM would be of great help.
Kubernetes is a good choice - When the application needs quick scaling, is already in microservice-based architecture, has no fixed traffic pattern, most of the employees already have desired skills.
- Upgrade without downtime
- Quick scaling
- Redundancy & uptime
- Flexibility to choose the various CNI & CSI options.
- Reduced downtime by more than 50%.
- Increased upgrade frequency by 30%.
- Avoided management escalations by 45%.
- K8s manage the workloads better as compared to OpenStack in terms of reliability, observability & reachability.
- K8s is not limited to only a single networking or storage solution as compared to OpenStack.
- Networking (which is a key concept) is much simpler in K8s as compared to OpenStack.
- It is possible to upgrade your applications without downtime in K8s but in OpenStack, you either have to divert the traffic or face an outage because you have to delete the whole stack & then recreate it.
Kubernetes - Open-Source container management
- Deploy applications on multiple nodes.
- Store application definitions in source control.
- Abstract away the implementations of storage and networking.
- Kubernetes is very high-maintenance compared to VM deployments in my opinion.
- Some failure scenarios are hard to recover from.
- High effort is needed for upgrading clusters and deployments to new versions of Kubernetes.
- Open Source
- Vendor neutral
- Declarative
- Positive: simpler deployment of new applications.
- Positive: better observability.
- Negative: more frequent maintenance cycles.
