We assist both application developers and end users of Kubernetes-based systems at all levels of operation.
Kubernetes-based containerization is gaining popularity by storm. There is nothing strange about it - it allows for very well-configurable management of a containerized environment, facilitates the implementation and development of applications, and provides unprecedented possibilities of scaling and monitoring applications running in a clustered environment. Designers of modern applications, both based on microservices architecture and monolithic, but cooperating with many components, wanting to equal the world systems, as one of the most common challenges, but also development opportunities, mention basing on docker containerization and the task of migrating to Kubernetes.
Due to the introduction of the level of abstraction, separating application developers from the complex mechanisms that perform all the above-mentioned functions, as well as the enormous possibilities of configuring for your own needs and using many independent components, Kubernetes is also an environment difficult to manage for teams with little experience with it.
As Hostersi, we help design, implement, monitor, and develop customer environments. Our services also include consultations regarding the solutions used. We share our experience, knowledge, and cases based on the experience of working with many differently constructed Kubernetes-based systems. Your team does not have to experiment on their own and painstakingly overcome subsequent problems. You can rely on the knowledge and skills of experts, gaining the necessary competencies in the course of cooperation to design your systems based on the best business and technical practices.
We are a certified Kubernetes service provider - Kubernetes Certified Service Provider (KCSP). With this certification, Hostersi customers are assured that they are working with a leading, internationally recommended company (The Cloud Native Computing Foundation (CNCF), which is part of the Linux Foundation) for the implementation and maintenance of Kubernetes environments.
Form of cooperation
As part of the provided services related to the Kubernetes environment, we delegate a team of engineers to work with the client, which includes architects, DevOps engineers, and system administrators. They are the ones who will get to know or design the specific infrastructure and the way the application works best.
The number of engineers depends on the size of the project and the planned period of cooperation, and they can interact directly with the client as full team members, or carry out the task on their own - depending on the client's preferences.
During the cooperation, we provide access to all technological knowledge of our company, e.g. networking, security, CI / CD, EKS, AKS, GKE, etc. With administrative care over the environment, we give our clients the possibility of 24/7 contact with engineers and access to a 24/7 hotline, allowing for quick and direct contact with administrators and operators in the event of a sudden failure. Online meetings are standard for design work. It is also possible to organize a meeting at the client's premises.
Basic technologies
Selection of solutions and technologies
A frequent task valued by our clients is to recommend the technology, configuration, and security mechanisms. For example, we talk about whether the implementation of Network Policies is needed, we show the possibilities of calico or flannel stacks, we help in the selection, configuration, and implementation of ingress controllers.
We agree with our clients the use of typical operational, security, or infrastructure patterns, such as the RBAC system, sidecar applications, service mesh implementation needs, and many others, increasing the level of customer experience and knowledge in these areas. We present to the client sets of good practices in all areas of Kubernetes-based systems management - we also perform such activities on demand for existing systems.
Design, installation, and management of Kubernetes clusters
Whether the planned or maintained cluster is implemented on-premise (including OpenStack, proxmox) or in the cloud, is it launched via managed services (EKS, GKE, AKS) or launched in self-hosted mode (kubeadm, kops) - we are ready to prepare for it. We know and use the Infrastructure as a Service tool (with an emphasis on Terraform) - we use them to manage the entire cloud infrastructure of our clients.
Migration of applications (workloads) to Kubernetes
Our team of DevOps engineers can guide the client through the process of automatic or semi-automatic implementation of new versions of the application in the Kubernetes environment. We have experience with CI / CD systems and methods of their cooperation with Kubernetes (eg GitLab, Spinnaker, Jenkins). We introduce our clients, we help design and develop methods of automatic installation and update of applications using helm, we support developers in the process of implementing the CI / CD pipeline
Customer infrastructure management
For clients, we implement the infrastructure management process based on K8s. We implement monitoring systems that collect metrics and logs, alerting them about undesirable parameters and events in the system.
Regardless of whether the monitoring is based on open-source technologies (Prometheus, Loki, Grafana) or implemented using commercial systems or cloud services (DataDog, CloudWatch, Stackdriver) - we can implement a stack of these solutions, develop, configure and operate them.
Implementation of solutions compliant with the GDPR and the PCI DSS standard
We have been hosting personal data for over ten years. We know which solutions are worth using to meet the technical requirements of the GDPR. We also prepare environments that meet the Payment Card Industry Data Security Standard (PCI DSS).
We ensure an appropriate level of security of the environments and infrastructures in which the data of payment cardholders are processed. As Hostersi, we have an ISO 27001 information security management certificate.
