Kubernetes Adoption
Our team is experienced in all major cloud providers – AWS, GCP, Azure. We also have experience with on-prem solutions including OpenShift, Tanzu and Bring your own Kubernetes. Our experience on varied platforms also makes us ideal partners for re-engineering and scaling pre-existing Kubernetes solutions, as well as for Kubernetes migration from one platform / solution to another.
We understand deploying Kubernetes on production can be complex. Our Kubernetes consultancy team will work with your engineering to ensure that things are done the right way and make sure that cost, management and maintenance overheads are minimized.

Kubernetes native Product Engineering
We have extensive experience in Kubernetes infrastructure component development and maintenance. This is not useful only for Kubernetes infrastructure or service provider companies, but also for companies with large Kubernetes deployments where it would be more advisable to develop in-house solutions for Kubernetes infrastructure.
For example, one might want to provide an additional level of security, authentication and authorization using Authentication webhooks for accessing various components. Another example would be the requirement of network policies for controlling access to the system.
While it might not always be required for smaller deployments, it brings a unique perspective at looking at solutions both from application as well as infrastructure perspective.
- K8S (compute/storage/network)Scheduler Extensions Development
- CRDs, webhooks based Management Application Development
- Automated enforcement of Network Policies
- Integration of Auth Webhooks, K8s native RBAC
- K8S CSI, CNI Drivers
- Overlay Network plugins
- Cloud Native Distributed Storage Stack
Cloud native Storage Solutions
Kubernetes provides a wide range of options for storage solutions from supporting various types of storages like block, object, file storage. It supports storage plugins (CSIs and extensions) from various storage vendors. It also supports various attributes and differentiated storage classes to be used. Application requirements need to be clearly understood and correct storage needs to be identified.
Choosing correct storage is very important as it does not affect only data availability, application scalability and performance, but can have substantial cost implications in case of public clouds.
Productising Kubernetes based applications also requires enterprise level storage features, be it on-cloud or on-prem. Features like storage backup, snapshots, data replication, ddup etc. might be required for different applications. In some cases certain RPO (recovery point objective) and RTO (recovery time objective) requirements would need to be met.
Our team has extensive experience in designing storage solutions for enterprise grade Kubernetes infrastructure. In fact our team was part of the first ever storage plugin (flexvolume) ever written and qualified for Kubernetes !
- Knowledge of different CSIs, every storage vendor has their own CSI
- Knowledge of various CSI extension drivers for using remote storage using NFS, iSCSI etc.
- Kubernetes Native Software Defined Storage
- Kubernetes Native Data Services (Backup, DR etc)
Infrastructure Modernization
Migrating applications to Kubernetes is effective and seamless when one uses Kubernetes native constructs to manage infrastructure components. It involves providing Storage management, network management, telemetry and observability constructs to applications so that it integrates seamlessly with Kubernetes echo-system. It is a fundamental step required for making an application robust and scalable using kubernetes.
We are adept at handling various different types of clouds and on-prem Kubernetes environments. Providing consistent metrics, visualizations, and alerting irrespective of deployment type ensures your engineering teams can maintain and optimize your cloud or hybrid environments. Correct provisioning of infrastructure is very important, so over provisioning costs are minimized and underprovisioning does not impact performance. Also Kubernetes infrastructure needs to be ready for burst-to-cloud scenarios.
- Expertise in infra components
– Networking, Storage, Security, Observability / Telemetry
- Modeling of infra into Infra-as-Code (ready to be deployed anywhere)
- Observability of Infrastructure Usage & Opex
Hybrid Cloud Management
Experience of integration with various CMPs (Cloud Management Platforms) like Rancher, Anthos, AWS, Tanzu etc. We have developed and worked with solutions that provide capability of migrating workload from one cloud to another. We have also designed burst-to-cloud solutions. This configuration allows applications on private cloud to “burst” into the public cloud and access additional resources without service interruption.
Experience with various types of deployments : Bare Metal / VM based, on-prem / public cloud based, Bring your own Kuberenetes (DIY) / Managed Kubernetes services. We have expertise in Kubernetes migration from one type of deployment to other.
- Integration with well-known K8S Control Planes (Rancher etc)
- Build DR, Migration solutions (move app from any to any cloud)
Kubernetes Site Reliability Engineering
Kubernetes is a complex system that is labor-intensive on maintenance. It requires good planning and mitigation. In order to deliver maximum value to your business, it needs to be done seamlessly without affecting availability of applications. It does tend to have high operational energy requirements.
From maintaining Kubernetes on a day-to-day basis, to providing you useful metrics in terms of system and application health, to support for security updates, to support for regular and major updates , to providing timely reports with relevant details on application failure our team can handle it all in a very dexterous manner. This allows your team to focus time and energy on meeting your customers needs.
- Keep track Kubernetes mailing lists and forums for issues reported and fixed
- Kubernetes currently has high release metabolism. Keep upto date with features and fixes in the releases.
- Kubernetes upgrades, irrespective of Kubernetes provider, are very complex, time consuming and delicate operations. We have lost count of the number of times we have done those !
Application Modernization
Application modernization should not be done in silo, and requires accurate analysis of application dependencies and use of correct tools and methodologies to address them. Depending on application complexity, it might require to strategically and incrementally refactor your monolithic application to microservices-based architecture. While converting application to microservice, various inter-process communication mechanisms also need to be ported to Kubernetes native constructs.
Each and every application and dependency maps are unique. So though underlying principles for application modernization remain the same, a tailor made approach and roadmap needs to be created to have successful migration.
In case an application can not be containerized and still needs to run in Kubernetes environment, we have expertise on Kubevirt based solutions which makes it possible to lift-and-shift VM to Kubernetes without requiring application containerization.
Of course, one needs to keep in mind the ultimate benefit of modernization – ease of deployment, maintenance, upgrade, scale and enhanced observability. These need to be taken into consideration while developing the roadmap.
- Containerization
- Microservices Architecture
- Easy Life Cycle Management (deploy, upgrade, scale etc)
- Built-in Observability features
- Automated High Availability, Load Balancing, Scalability
- Use of Kubevirt and KVM based VMs for lift and shift if required
Cloud Native Networking Services
One of the most important aspects of cloud migration and application migration is how to expose microservices, so integration becomes seamless and secure. Things like application failover, scaling applications up or down, application monitoring, burst-to-cloud etc. need to be considered.
Clear and well-defined communication with the network or system admin team is required, so that correct rules are configured on networking infrastructure. For managing, supporting and debugging network services, we have expertise both on infrastructure side like ToR switches, Gateways, Routers etc. as well as on Kubernetes side like Kubernetes network policies, Load Balancers, ingress, node port, cluster IP, headless services etc.
- Knowledge of different CNIs, every cloud provider has different default CNI
- Setting up DNS and Network policies for Kubernetes
- Service mesh
