Building High Availability Resilience for a Global Appliances Player
How Umbrella Infocare Helped?
Umbrella Infocare has been a constant driving force in the tech journey of the prominent Appliances brand, beginning with cloud migration and moving on to Managed Services for continuous value on cloud, DevOps for faster testing and delivery, cloud security, AWS Best Practices and more.
Disaster Recovery Environment Needs
The global appliances solution provider had CtrlS data centers housing more than 150 virtual servers that support various critical internal and customer facing applications. While they have already moved many workloads to AWS, some workloads remain on-premise. The client was facing downtime for some critical applications on-premise and the existing Disaster Recovery (DR) solution was not suitable for their changing needs.
The client considered various DR solutions and with Umbrella Infocare’s help decided to set up a Disaster Recovery (DR) Environment in Amazon Web Services (AWS) Mumbai Region for their servers in their on-prem data centers.
RTO & RPO
Robust DR Stance
Dependable and resilient failover solution to ensure minimum downtime and business continuity
Automatic functioning and resilience of App & DB services in the DR environment
Major reduction in Total Cost of Ownership (TCO) for faster recovery
Ensuring Smooth Disaster Recovery on AWS for Appliance Leader
The Umbrella Infocare team also helped the client implement the DR after conducting a Proof of Concept (PoC). The solution we offered was based on the Pilot Light DR strategy and involved the following:
- Deployment of target region infrastructure with a new VLAN and DR VPC
- Setup CloudEndure for replicating their applications and Database server in near real-time to AWS cloud
- Use CloudFormation templated to quickly build infrastructure in the event of disaster using CloudFormation.
While we deployed a highly resilient infrastructure on AWS, we also optimized the DR environment for cost savings:
- Only replicating instances are running with Elastic Block Store (EBS) volumes and target compute
- The infrastructure is only launched during the DR drill or in the event of a disaster
We conducted a successful DR drill for the failover activity that helped validate the RTO and RPO and application ensuring smooth backup and recovery. We also provided a Runbook of the complete DR drill as SOP to the client for reference in the event of disaster recovery. The SOP charts out a well-defined DR drill process and acts as a clearcut guide for triggering failover process during an actual disaster.
Configuration of Network infrastructure in the DR environment including the VPC and subnets
Configuration of VPN/Direct connect between production datacentre and staging area VPC on AWS
Realtime, block-level replication in AWS staging area and data replication over secure channel
GUI-based interface for continuously monitoring the replication status of the server
Leveraging AWS to Enhance RTO and RPO
After Umbrella Infocare setup the DR environment on AWS Mumbai region for the home and life solutions provider, they realized the following benefits:
