VA Linux is a company of open source experts who keep on working toward the growth of open source technologies. Besides being Linux kernel experts, many of our developers have been taking lead roles in OpenStack, KVM, Xen and Open vSwitch projects. This knowledge, along with a detailed understanding of issues from the source code level and above, enables a swift response to our clients' advanced and specialized needs.
Kernel analysis at the source code level in response to kernel-related system crashes and system hangs. Likewise, our team possesses an expertise in determining whether problems exist with kernel itself or with the applications, an expertise which they can offer. Various methods to correct or avoid future occurrences for many open source software such as KVM and Xen can be offered as well.
Open source software such as KVM, Xen, CloudStack and OpenStack analysis designed to identify performance bottlenecks and to improve system performance.
Issue examinations, problem clarifications, suggestions for improvement and support the roll-out of virtualization and cloud computing technology
Technical and industry trends analysis of open source software including Linux kernel, virtualization and cloud computing.
VAQuest offers failure analysis solutions for mission-critical systems by using open source software in complex IT client/server environments from the code-level with crash dump analysis, failure analysis, proposal to avoid future failures and providing the correct patches.
VA Linux supports the design and development for mission-critical systems, cloud computing infrastructures and server/network virtualization with functional improvement, tuning and OSS architecture/missing functions development.

VA Linux provides instructive proposals, research, analysis, verification and evaluation reports in order to build system infrastructure with open source software.
We strive to help and support our clients when it comes to sorting out the many issues involved in employing Linux kernel and other open source software so that it will meet specific system- and product-needs. The company is also dedicated to continuously working to help clients clearly understand areas where/how their system can be improved.
The professional services will be available to support a wide range of open source technologies.
Kubernetes written in Go is a powerful open source platform meant for the automation of deployment, scaling and management of containerized applications across clusters of hosts.
AWS and OpenStack are virtual machine-oriented platforms, whereas Kubernetes is an application-oriented platform that is suitable for the management of containerized applications.
Kubernetes was originally developed and designed by engineers at Google and was created as a result of learning from the application-oriented platforms Borg and Omega.
Kubernetes was introduced as an open source version of Borg in 2014 by Google and after 2016 the Cloud Native Computing Foundation (CNCF) hosts Kubernetes activities such as development and project management.
REST API allows container management across multiple nodes.
By simply increasing the number of nodes, you can easily extend cluster resources (CPU, memory, disk) without affecting other existing services.
Independent application deployment.
Scale in (out) applications while operating a system.
Seamlessly deliver new functions of applications.
Rolling updates allow deployments’ update to take place without downtime by incrementally updating Pods instances. Also, all of the Deployment’s rollout history is kept in the system so that it can be rolled back at any time.
The Kubernetes Cluster centrally manages information such as common settings and database password which is then used from application of container. This structure uses etcd.
If a pod goes away, the Kubernetes control plane detects this status and automatically restarts the pod in accordance with Spec.
The implementation of original functions and utilization of the platform itself as a framework. By using this extensibility, you can also implement your own resources for Kubernetes.
Providing an externally-accessible IP address that sends traffic to the correct port on your cluster nodes, provided your cluster runs in a supported environment.
