Scope International is the Global Shared Services Centre of
the Standard Chartered Group. The company was incorporated in 2000 and commenced
actual operations in Chennai from 2001. In a short span, Scope has grown to
become an organization with over 5,000 employees and constitutes about 8% of
Standard Chartered Group’s global workforce. It services all 56 countries of
the Group and processes over 80 mn transactions a year in banking operations
alone. Scope handles a wide range of value-added and complex services from
banking operations to supporting global HR processes, finance and accounting
services, software development and maintenance, and providing IT service and
helpdesk support to the group globally. With these processes in the back drop,
the bank’s connectivity and network infrastructure assumes a mission critical
role. Sarabjit Anand, head ITSC (W) and country technology manager India
and GSSC, Scope International, walks through the company’s networks in an
interview with Shrikanth G of Dataquest. Excerpts
How critical are the Networks for you?
A few years back we decided to move towards a network centric model as part
of our strategic vision. The initiative was started three years back, and we
moved our core and critical application to our data center. The network centric
model called for strategic and well defined networks for seamless operations.
For instance, from a group perspective, we established 10 core sites spread
across countries like India, Hong Kong, Singapore, Malaysia, UK, UAE among
others. With this model in the backdrop, our network needs to be up and running
always to meet the stringent requirements of Standard Chartered Bank’s (SCB)
operations. So in that perspective, our networks play indeed a mission critical
role as all our apps sit in the centralized data center.
How is the model defined?
Our networks are defined in three layers. For instance, the first layer is
the core, and then we come to the second layer that is distribution. The third
one is the access layer. The ten sites that form the core are fully redundant
MPLS based network. Then we come to distribution and when we take one of the
core sites like India- within it we have two sites- Chennai and Mumbai, these
are next level critical sites that drive the banking operation at the country
level. So all bandwidth lands in these critical sites and then gets distributed
across through the access layer.
How do you manage connectivity in your network model?
With ten core sites, the need for a reliable yet agile connectivity backbone
is a must. We used different types of connectivity and multiple vendors, and
arrived at a connectivity paradigm that meets our needs and requirements.
International connectivity is primarily MPLS and we use IPLC in a small way. Our
domestic connectivity is through leased lines enabling point to multi-point
connectivity. We also use VSAT, but in a very limited way.
Choosing a connectivity vendor is critical for operations, given
that what’s your approach here?
Our connectivity infrastructure is made up of multiple vendors. We
deliberately adopted that approach to arrive at a network that gives us
resilience. Moreover, we are not tied with one vendor as multi-vendor approach
gives us flexibility and heterogeneity in-terms of managing our networks
effectively. We have defined standards in every areas of IT and network is no
When we factor typical banking operations such as the ones
spread across branches, ATMs, e-Banking etc. How big are these challenges from a
SCB is in 21 cities and 81 sites in India. Some of the sites are support
offices. But providing connectivity is indeed a primary requirement for all
branches to successfully connect and interconnect with each other. We have 198
ATMs in India and this calls for systems to always be linked and, hence, network
availability is extremely critical. We have a primary set-up and a back-up, with
dial-ups as the back up. This combination of leased, dial-up and VSATs works
well for us to arrive at securing peak uptimes for our ATM operations.
What about network security?
Security is of paramount importance. One is our own banking operation that’s
internal. The other one is external customers linked to us through our websites.
In terms of managing the network security internally, we have well defined
controls and access from inside to outside. For instance, only authorized people
are able to access applications, and it is multi-tiered with various levels of
access. We also have three-tiered firewall for Internet banking operations and
the best proactive practices to control spam and spyware.
In terms of applications, can you give us a snapshot?
We have a core banking application called ‘Hogan’, which India uses and
it is housed in our data center in Hong Kong. All our locations in India use
this CBS application. We also use payment-based applications like RTGS with our
What are your key goals through the network centric model?
Our two key goals here are availability and scalability. I think these are
the two most critical factors that define the efficiency of the networks. For
instance, the networks we have created should be available to the banking
operations spread across many locations. From accessing the apps to a simple
function like email, the networks form the backbone and any downtime in that is
totally not acceptable. Meanwhile, any network has to be scaleable to the
business expansion and growth coming out of it. For instance, SCB is going on an
aggressive growth mode and our networks have to meet that without any stress. To
take stock of things from a network perspective, a while back, we have launched
a network re-engineering program aimed at further improving our overall network
backbone. We are enabling our network to future demands. For instance, once the
re-engineering program gets completed by this April, we would have bandwidth
capacity that would be 5 to 20 times higher than what we are currently having.
On new technologies…
Since we adopt a standardized approach, any new technology has to be tested
fully and we need to be comfortable to deploy that on an organizationwide basis.
Hence, our use of technologies like Wi-Fi is limited to conference rooms. And
here also, we have adopted restricted wireless usage through token-based access
and not everybody can access it. As for technologies, we are looking closely at
VoIP, where in we have created some proof points and are exploring the
possibilities of deploying it.
What are the key challenges CIOs face today in managing their
enterprise networking infrastructures?
I think the twin challenges revolve around availability and scalability. Any
network planning has to be done with growth in mind. Here you need to create a
network that is able to take up the current requirement and provide round the
clock availability. But QoS changes very frequently, and one needs to constantly
scale up the networks to accommodate new requirements. For instance,
applications and access patterns keep changing. Yet another key challenge I
consider lies in prioritization of the networks. One should be always aware of
what goes on in the network and need to put in place pro-active monitoring
mechanisms in place that ensures a secured and reliable network backbone.
