We design and implement fault-tolerant automated infrastructures based on Kubernetes that provide high availability of services in production.
What is it and why is it needed?
Manually launching and configuring heterogeneous applications on the same server (or in the same virtual machine) often leads to errors - with versions, paths, libraries.
The solution to the problem has long been known: containers. And the most popular containerized application management system is Kubernetes, an open source platform developed by Google.
You have a ready-made project that has “taken off” and wants to be sure that it will not “fall” due to the lack of dedicated specialists for the Kubernetes cluster.
Who is Kubernetes for?
Your project has already reached a plateau, and you need to know for sure that everything is set up correctly and there will be no disaster tomorrow.
It is clear that there are problems, but it is not clear where exactly? We'll help you find the answers.
As a company implementing Kubernetes for a client, we will first assess their requirements and objectives. We will review their infrastructure, networking, storage, and security configurations to determine how Kubernetes can help them achieve their goals.
After assessing the client's needs, we will propose a Kubernetes implementation plan that meets their requirements. We will work with the client to finalize the plan and obtain their approval before proceeding.
With the client's approval, we will proceed with the installation of the Kubernetes software on their infrastructure. We will set up the Kubernetes cluster, configure the networking and storage, and set resource quotas and limits as needed.
How we are working
Once the Kubernetes cluster is installed and configured, we will proceed with deploying the client's applications on the cluster. This will involve creating Kubernetes objects such as pods, services, and deployments to define the application deployment and scaling policies.
To ensure that the client's applications can handle increased traffic and demand, we will configure the auto-scaling policies provided by Kubernetes. This will ensure that the applications can scale automatically based on demand.
We will set up monitoring tools and dashboards to track the performance and health of the client's Kubernetes cluster and applications. This will help us identify issues and troubleshoot problems quickly.
Once the Kubernetes implementation is complete, we will provide training to the client's IT team on how to manage and maintain the cluster. We will hand over all necessary documentation and provide ongoing support to ensure that the client can use Kubernetes effectively over time.
Kubernetes Audit
We will check the stability of Kubernetes clusters to insure you against accidents or evaluate the quality of work of infrastructure contractors
You can see that during operation, random restarts of applications in the cluster happen.
You have encountered problems or downtime in the process of deploying new versions of applications.
You want to add functionality and understand how to do it right.
You need to check the integration of the solution to be sure that the pipelines are correctly adapted and the interaction between the systems is normal.
You want to check the quality of outsourced cluster deployments before accepting them.
There is a need to make sure that the security policies in the cluster are configured correctly (and that they even exist).
There is a need to cut costs, but you don't know where to start.
When it's needed
Checking the installation according to the checklist with the
conclusion that the cluster is ready for scaling and moving to a
new stage of development.
Inspection of applications and
conclusions about their working condition and ways to improve
efficiency.
Verification of solution integration, including interaction between systems and load assessment.
Revision of security policies with ingress analysis and role-based access control.
A roadmap for expanding functionality (for introducing blue / green deployments, creating a geo-distributed failover cluster, switching to GitOps, etc.).
Analysis of monitoring (monitoring of nodes, applications,
resource consumption, delays).
Analysis of the backup scheme with checking the method of backing up the state of the cluster and deploying the cluster.
Analysis of costs with optimization of costs for tariffs in the cloud and / or for physical servers.
Fault tolerance analysis with verification of installation, master configs, node substitution.
Pipeline analysis with workflow check.
Analysis of the storage system with a check of its fault tolerance and performance.
Scalability analysis.
