Disaster Recovery Program for business critical applications to ...

Project Category:?Corporate
Sub Category: Enterprise Technology Solution
Reference No.:?PSE2013/awards/39

Details of?Programme?/Project/Initiative:

Brief Description:
IT-DR program was initiated to safeguard the business critical applications in case of any natural, manmade disaster & thereby ensuring business continuity and minimising business losses. Currently there are total 11 businesses critical applications along with 11 surround applications present & operational at Disaster recovery site. To achieve the objective of disaster recovery of IT applications the agreed Recovery time objective (RTO) is set for 4hrs as well as Recovery Point Objective (RPO) is for 2 hrs with service partner.

Objective:?Objective of DR was to enable business continuity in case of disasters and provide a. Continuous availability of customer services b. Safeguard interest of key stakeholders, reputation, and brand. C. Minimize business losses

Target Group:?11 business critical applications

Geographical Reach within India:?NA

Geographical Reach outside India: N/A

Date From which the Project became Operational:?15-12-2012

Is the Project still operational?: Yes

List 5 key achievements of the programme/project:

1.?Nearly 100% Availability of business critical Systems to run the show
2.?? Operational Excellence ? Data replicated & secured with minimal or no impact to the production environment ? Quicker availability of applications at DR through Automation ? System health checks through online Dashboards and periodic Reports ? Reduced planned downtime windows & costs
3.?Minimize Business and Revenue risks
4.?Achievement of compliance requirements by conducting regular periodic drills
5.?Achievement of RTO, RPO as per the agreed SLA.

List 5 key challenges faced while implementing the programme/project/initiative and how they were overcome:

1.?Complex Production environment Since production applications are tightly integrated and dependent, hence, in addition to DR scope applications, core dependent applications were also introduced in the DR site so as to reduce the impact of non-availability of business services in post DR scenario.
2.?Adverse impact on production environment. With the use of Hybrid solution for data replication, the impact on production was either mitigated or simplified. Like use of data guard helped not only replicating data at DR site but also helped in reverse replication too.
3.?Product scalability and support issues. Evaluated multiple solution to arrive at a hybrid solution which is scalable, cost efficient, robust and reliable with proper reporting and alert mechanism. The Oracle data guard with IBM global mirror solution was implemented to address these issues.
4.?Extremely high data volume for replication. Data volume of DR scope applications was extremely high it was very difficult to replicate at DR site due to continuous data processing. This was mitigated using the hybrid solution where in the Oracle DB archive were asynchronous replicated at DR site.
5.?High bandwidth requirements. Having voluminous data replication at DR site was resulting in extremely high bandwidth i.e in terms of GB which was proving a very costly solution on YoY basis. This was also solved with the use of Hybrid solution which helped minimize the BW requirement by 70%.
