DR on AWS Cloud Success StoryBCDR

A B O U T T H E C U S T O M E R

Srei Infrastructure Finance Limited ("Srei"), a Kanoria Foundation entity, is one of India's

largest holistic infrastructure institutions, constantly and consistently delivering

innovative solutions in the infrastructure space. Srei, derived from the Hindi word ‘Shrey’

meaning 'merit' or 'credit'.

The company has been in the business for nearly three decades and has come a long way

after starting its journey perhaps in one of the most difficult and challenging times. In 1989,

India had not opened up its economy, which during those times, was in doldrums. There

was hardly any quality investment in infrastructure projects. Srei was born then, a child of

a dream, with the aim to address two of the most critical problems in our country then –

financing and infrastructure. Today, Srei has close to USD 5.5 billion of consolidated assets

under its management.

HistorySREI is a part of the grandlineage of KanoriaFoundation. 

SREI had hosted their most of their mission-critical applications which require high

system up-time and resiliency with a leading Data-center service provider. DC was

located in New Delhi, without having a DR  was single point of failure in the event of any

outages, frequent outages in the recent past, even took over a week to resume the

application availability inevitably resulted in huge business impact at the customer's end.

Problem sets defined were:

a. High Capital Investment in procuring infrastructure.

b. Outages resulting in both loss of business and brand value.

c. Difficulty in scaling the infrastructure.

d. Operation cost on 3rd party service provider on DC support for maintenance.

e. No cost-effective solution for setting up the DR which was mandated by RBI.

f. The lengthy process of discussions and negotiations during a hardware refresh.

g. Slow and deteriorating hardware stack hampering performance.

SREI has migrated 25 Applications including 4 business critical applications built on Dot NET

v4.x, using database as Oracle 11G R2  & few custom applications which runs on

Dot Net v4.x and back-end DB as Oracle & MSSQL on  AWS embracing best practices with

guidelines for implementation.

Housing 65+ windows based instances ,40+ Production instances & 25 Development & Test

environment. 

 

Minfy’ s Enterprise Cloud Architects worked with the Infrastructure team of SREI Core

IT Infrastructure team  to design a highly scale-able & fault tolerant Disaster

Recovery on AWS paying special attention to maximizing the availability and ensuring

business continuity for all the core applications.

Minfy devices out the plan to migrate 25+Microsoft  based Dot Net Applications which 

includes 4 - Business critical most applications  & 20+ internal applications  on AWS by

leveraging the Advantages of  different AWS services. Starting with DR environment

and then production.

Minfy  reduced capital and operational costs by recommending  an alternative for

the on-premise infrastructure  for the DR site , instead of that adopting the new scale-

able infrastructure on AWS. Minfy started the migration of production server for

SREI  with a complete due-diligence of their existing infrastructure along with the

special focus on economics /TCO, migration plan has been detailed with ownership and

recommendations .

Minfy's Implementation team along with the Cloud architects worked with Infrastructureteam & business stakeholders of SREI to derive out the migration plan to ensure on zero /very minimal interruption to the website’s availability. To finalize the Migration plan, it’s started with BIA Analysis, risk assessment, CostAnalysis, Priorities established with inputs from SREI, prioritization done for functionaloperations, information flow, processing systems used, services provided inputsgathered as most practical alternatives possible in case of DR. 1. Applications were moved both in a manual and automated fashion. While simplerhomegrown web applications were migrated manually complex ERP and Legacy Financeapplications were moved using CloudEndure. 2. For block-level synchronization of databases to CloudEndure was leveraged. 3. File system integration achieved leveraging Minfy’s Intellectual proprietary applicationCloudStorz. As per the use case, S3 bucket needs to be mapped as the drive for the coreapplication for which a 3rd party application TNT Drive was used. 4. Migrated on-premise P1 legacy  applications servers hosted on windows platform toAWS via AWS VM Import/Export service as they have multiple challenges in setting upthe same on a new windows ec2 instance on AWS. 5. The additional domain controller has been set up on AWS environment from scratchalong with client by syncing the same with on-premise Primary Domain Controller toperform successful DR drill on AWS environment as client's most applications were ADdriven. being additional domain controller already configured it helped for successfulapplication usage on DR site. 6. Session management & load balancing achieved using the AWS Elastic load balancerfor multiple windows terminal servers for which houses P1 application stack. 7. For smooth DR transition of dynamic .Net Application's content,for data transfer fromon-premise  DC to DR site we have used our native tool CloudStroz which works onupload mode in DC site and in download mode in DR site having S3 as the repository. Soin the DR site when the application instances were up having this back-end mechanism ithad all the updated data in place and ready to use.

The value proposition shown by Minfy & AWS, convinced the client to make the DR which was

set up on AWS as primary datacenter & the third party DC provider as DR.

The total cost of operations of the DR was optimized at 15% of primary DC TCO.

Minfy’s DR Solution was audited & approved by Gartner without any observations and

changes helped in setting the stage for BFSI & NBFC customers to start cloud adoption.

DR Drill was immensely successful with zero data loss.

All the P1 application servers started within the stipulated RTO of two hours.

Minfy as an Omni  channel solution for SREI from the design of the solution,

implementation to managed services support (24*7) helped SREI to focus more on their

core business.

External auditors from Reserve Bank Of India audited & approved the DR set up as it

complied to all the regulations governed.

DR on Cloud strategy was presented by SREI in the Gartner symposium and was highly

acknowledged by the industry and opened doors to a lot of BFSI & NBFC customers to start

cloud adoption for DR with minimal investments.
