1.5 years (ongoing)

Our customer is a prominent insurance carrier based in the United States, providing services to small and mid-size businesses globally.

Besides engaging Symfa in the implementation of a wide series of legacy modernization projects, the customer sought assistance with infrastructure-building tasks in the Kubernetes environment. Initially, all DevOps-related tasks were on a team of engineers from the client’s side. But as with the project expansion, increase in the number of on-premise servers, and growth in the number of applications deployed in the infrastructure, the customer decided to involve additional forces in the form of DevOps professionals from Symfa.

The most challenging task to tackle is to maintain consistency of all applications deployed in multiple clusters within the complex Kubernetes environment.

To prevent malfunctions in clusters resulting from the unsynchronized system and different applications’ versions our DevOps engineers keep an eye on maintaining similar versions and configurations of the apps.

To alleviate the synchronized work of all team members, ensure automated updates, and keep better control over deployments, our engineers introduced the GitOps approach through the ArgoCD tool. This also facilitates troubleshooting efforts in the event of failures, ensuring smooth and consistent operation of the entire system.

The most part of the customer’s infrastructure is located in dedicated servers in the client’s local data centers. These servers are merged into one working machine and are used as a virtual environment. The environment, in its turn, is divided into clusters where the customer’s applications are deployed, and have different spaces with appropriate access configurations depending on a project type.

To ensure error-free functioning of applications deployed in clusters, our DevOps engineers adhere to the Infrastructure as Code (IaC) approach in the Kubernetes environment at the customer’s on-premise servers. The Infrastructure as Code (IaC) model facilitates automatic deployment of the infrastructure along with preconfigured applications. Utilizing ArgoCD+Ansible, we achieve the seamless deployment of the entire infrastructure to any environment through app templating with just a single button click. Our team members add and fine-tune infrastructural utility for Kubernetes, deploy new applications in the environment, and deal with containerization. For new app deployment, Symfa’s DevOps engineers apply the GitOps approach through Ansible and ArgoCD tools, so new app versions can be deployed directly from the repository.
