HCLTech RecoverNxt Offering

RecoverNXT is a framework that provides end-to-end DR service across enterprise infra landscape leveraging features stitched under workflows to perform tool-based replication across application layers. it uses S3 for storage, EC2 for compute, general purpose storage and other AWS infrastructure components as per the solution requirement.

RecoverNXT framework consists of four phases and are as follows:

1. Assessment: Involves discovery and analysis of customer’s current environment. Gain information on various application dependencies, existing DR strategy and roadmap.

2. Design and plan: A solution approach is designed, and the best fit tool and deployment model is finalized. The solution design/approach also maintains the project scope. A blueprint for execution is created which consists of selecting tools, finalinzing the project scope, project timelines, etc.

3. Build and Implementation: Involves execution of the project activities as per the defined timelines like configuring the tools required, setting up the DR infrastructure, application onboarding, building DR workflows and testing & vaildating DR drills.

4. Operate & Signoff: In this phase the DR drills test reports are shared with the client, knowledge transfer take place from BAU team to the client. The environment is kept under Hyper care support. The operations are then handed over to the BAU which may exist within HCLTech or at the customer’s end.

The RecoverNXT framework encompasses DR management which provides managed DR solutions to build, operate and manage DR workflows and operations. The framework leverages third party tools serve following use cases:

• On prem to Cloud – Switchover / Failover and switchback/failback of applications from Physical & Virtual Servers at Production Datacentre to hyperscalers. Hot-Warm and Hot-Cold DR Strategies as per the Application Requirements. Supports both Low RPO – Low RTO solutions and Low RTO-High RPO Solutions. Also provides the benefits of scalability and elasticity of resources when needed.

• On prem to on prem – Switchover / Failover and switchback/failback of applications from Physical & Virtual Servers at Production Datacentre to DR site. Hot-Warm and Hot-Cold DR Strategies as per the Application Requirements

• Cloud to cloud – Switchover / Failover and Switchback/Failback of applications from Instances at in Public Cloud to the DR Instances at Public Cloud, Hot-Warm and Hot-Cold DR Strategies as per the Application Requirements.

• DR Automation & Orchestration - The solution framework has capabilities to provide DR process automation and Orchestration, DR drill Automation. It has the capability to provide DR drill automation leveraging Azure DevOps or GitHub providing efficient DR drills by testing the readiness of client’s environment for potential disruption.

• Kubernetes- The solutions have the capability of integrating disaster recovery seamlessly into Kubernetes app deployment, ensuring apps are protected from the start. The replication and DR within the Kubernetes environment can either be provided by using native storage and CSI snapshots to create up-to-date copies of the data present in the environment or through Journaling to enable the checkpoints with a granularity of seconds.
