Customer → A leading mobile IOT solutions provider

Size → 200+ users worldwide

Our client, a leading mobile IOT solutions provider, had their on-premise mobile solutions running in their primary Data Center in Oregon. In the event they had downtime issues with their applications, their basic disaster recovery approach was to failover to a secondary Data Center in Las Vegas. Data was synchronized between the two data centers using standard data backup mechanisms. This approach however did not scale very much as:

• Procuring and provisioning new infrastructure was a nightmare thereby impacting
• their overall time to market.
• Recovery time objective (RTO) and Recovery point objective(RPO) were higher
• leading to longer application downtime.
• Resource Overheads to manage the resources in primary and secondary data
• center were higher

The proposed architecture by Aplima was to run and maintain client’s mobile application

on a minimal footprint of Amazon EC2 Instances or AWS infrastructure (warm standby) to meet Customer’s required RTO and RPO.In the case of failure of the on-premise production system, the standby environment would be scaled up for production load , and DNS records would be changed to route all traffic to AWS.

As part of the design implementation:

• Used Virtual Private Cloud to provision a logically isolated section of the AWS Cloud 
• Set up OpenVPN and Bastion hosts to allow corporate users login to AWS
• infrastructure
• Created and maintained Amazon machine Images using t2.small instance type for
• the web and application servers.
• Set up CloudFormation templates to scale the infrastructure for production load.
• Set up AWS RDS MySQL instance to replicate(mirror) data from on-premise MySQL
• server.
• Set up Elastic Load Balancers to distribute traffic to web and application servers.
• Leveraged Simple storage service to store cloud formation templates and all logs.
• In the event of a failover:
• Used highly scalable and available Route 53 service to route end user requests to
• infrastructure running in AWS.
• Increased the size of the web and application EC2 instances in service with the ELBs.
• Increased the size of the RDS MySQL database instance for the production load.
• Created read replicas for increased performance.
• Used CloudWatch and AutoScaling to monitor and right-size the fleet or
• accommodate the increased load

Setting up warm standby disaster recovery in AWS drastically reduced the recovery times

by leveraging the minimal footprint running on AWS and quickly provisioning

pre-configured AMIs with the automated templates in the event of a disaster, all at a

fraction of cost of traditional DR approach.

• Cost-effective DR solution
• Scalable DR infrastructure
• Failover capability
• Minimal downtime

• Detailed cost analysis on setting up a traditional DR site vs setting up a DR site in AWS.
• Pre-configured AMIs
• CloudFormation templates to scale the infrastructure to production load
• Database mirroring to RDS
• Failover capability
• Monitoring and automated scaling
• Documentation of new DR solution

• Review of the existing infrastructure
• Cost Analysis of DR solutions
• Proof-of-Concept for proposed DR solution
• Implementation of DR solution
• Admin Training

• A cost effective DR solution which
• Was 55% lower than a traditional DR solution
• Met Client’s Recovery Time Objective
• Met Client’s Recovery Point Objective
