Kubernetes Cluster Management

Leverage the advantages of reliable Kubernetes clusters for software product development and highly performant scalable applications. We provide all kinds of expert Kubernetes support and services to help our customers use their cluster-based container systems with maximum efficiency.
What we do

SHALB has years of experience in managing Kubernetes clusters, with hundreds of successfully implemented projects. Our customers benefit from secure, production-ready Kubernetes clusters, whether cloud-based, on-premise, or hybrid.

Our services include:

  • Migration of a customer’s infrastructure under Kubernetes management
  • Self-hosted Kubernetes clusters
  • Managed Kubernetes clusters
  • Kubernetes multi cluster management
  • Autoscaling
  • Multi-cloud solution
  • Cluster deployments with GitOps
  • Monitoring cluster performance metrics
  • Kubernetes cluster security
How it works

We can configure and deploy your Kubernetes infrastructure on AWS, GCP, Azure, or on-premise platforms like VMware, Rancher, and OpenShift. We also have experience with setup and management of Kubernetes clusters running in edge environments.

Our team will ensure that your clusters are fault-tolerant and highly available by using multi-DC architecture – an approach that lies in hosting a cluster in two datacenters at a time; should the active one fail, the incoming traffic is redirected to the redundant one with no downtime.

The top-notch monitoring system is based on open source tools from the Kubernetes ecosystem. It provides full visibility of your Kubernetes resources and operations, including performance metrics and graphs, monitoring of control-plane, and container health.

An advanced security system is based on best security practices and includes cluster isolation, RBAC, IAM policies, configuring Security Context for pods and containers, centralized secret storage, etc.

Benefits of managed Kubernetes services

To help customers deploy, manage and scale their containerized applications with confidence, cloud providers offer managed Kubernetes services on their platforms. Such a service includes administering the Kubernetes master nodes and all the processes running within it.
Reduced operational complexity and easy cluster upgrades.
Secure by design clusters with automated security patches of your control plane.
High availability due to a cluster’s control plane redundancy across availability zones.
Seamless integration with other services from the cloud provider for built-in monitoring, scaling, and load-balancing.
Fully compatible with Kubernetes cluster management tools, support various Kubernetes  distributions.
Autoscaling and flexible resource provisioning.

“What I liked about Volodymyr and Sergii is that they would figure things out. They were very proactive in finding the resolution to every little issue and figuring it out and doing the research. That was nice to see. We were leaning on them for their expertise as the process went on. I think they did a great job on that and figured out a lot of little details.”

“The problem with our project was we had so many people working on it that it was very convoluted, – comments Olexy Sadovy. – So it was tough to untangle all this mess. And I think SHALB did a great job of working with that. We had a couple of bumps but we got through that and I think we ended up on the good side of it.”

“The solutions proposed by Shalb have proven their quality over time. The built cluster turned out to be easy and cheap to scale. Using it, we easily increased the number of clients we can serve at the same time by tenfold, without proportionally increasing the size of our team.”


How do I manage multiple Kubernetes clusters?

Managing multiple Kubernetes clusters can be simplified by utilizing cluster management tools such as Kubernetes Federation or cluster orchestrators like Rancher. These tools enable centralized management and provide a unified view of all your clusters, allowing you to streamline operations, apply consistent configurations, and automate tasks across multiple clusters effortlessly.

How can I manage security between two apps in a Kubernetes cluster?

Kubernetes offers various mechanisms to enhance security between applications. You can leverage Kubernetes’ built-in features like network policies to control traffic flow between different applications within the cluster. By defining specific rules and policies, you can restrict communication between apps based on namespaces, pods, or labels, ensuring secure isolation and minimizing potential attack vectors.

What is the benefit of migrating my infrastructure under Kubernetes management?

Migrating your infrastructure to Kubernetes management brings several benefits. It allows you to leverage the scalability and flexibility of Kubernetes, enabling faster deployment of applications, efficient resource utilization, and simplified management of containerized workloads. Additionally, Kubernetes offers advanced features like automatic scaling, load balancing, and rolling updates, enhancing your infrastructure’s resilience and agility.

Can you explain the difference between self-hosted and managed Kubernetes clusters?

In a self-hosted Kubernetes cluster, you are responsible for setting up, configuring, and managing the cluster infrastructure yourself. On the other hand, managed Kubernetes clusters are fully managed by a service provider, taking care of cluster setup, upgrades, patching, and maintenance. Managed clusters free you from infrastructure management tasks, allowing you to focus on deploying and managing your applications.

How can Kubernetes multi-cluster management benefit my organization?

Kubernetes multi-cluster management enables centralized control and coordination across multiple clusters, whether they are located on different cloud providers, data centers, or edge environments. It offers better resource utilization, workload distribution, and improved fault tolerance. With multi-cluster management, you can deploy applications across clusters, replicate data, and ensure high availability and scalability for your services.

Can Kubernetes clusters be deployed across multiple cloud providers (multi-cloud)?

Yes, Kubernetes clusters can be deployed across multiple cloud providers, a configuration commonly referred to as multi-cloud. Kubernetes provides the flexibility to create clusters that span different cloud environments, allowing you to take advantage of the unique features and capabilities of each provider while avoiding vendor lock-in. This approach enhances resilience, reduces single-point-of-failure risks, and provides geographical distribution for improved performance.

How can GitOps be used for cluster deployments?

GitOps is an approach to infrastructure and application management where the desired state of the system is defined in a Git repository. For cluster deployments, GitOps enables you to declaratively define your desired cluster state and configurations in version-controlled repositories. Through automation, any changes pushed to the repository trigger the system to reconcile the cluster state, ensuring consistent and auditable deployments.

What monitoring capabilities are available for Kubernetes cluster performance metrics?

Kubernetes offers a robust ecosystem of monitoring tools that can provide visibility into cluster performance metrics. Popular tools like Prometheus and Grafana can be used to collect and visualize metrics related to resource utilization, application performance, and overall cluster health. These tools enable you to monitor and analyze metrics in real-time, set up alerts, and gain insights for capacity planning and troubleshooting.

How does Kubernetes ensure fault tolerance and high availability for clusters?

Kubernetes achieves fault tolerance and high availability through its architecture and features. By leveraging concepts like pod replication, automatic scaling, and distributed control plane components, Kubernetes ensures that if a node or pod fails, the workload is automatically rescheduled onto healthy nodes. Additionally, features like cluster auto-recovery and multi-DC architecture further enhance fault tolerance.
