The Challenge
Building highly available, scalable and secure applications was getting difficult and extremely costly in their on-prem (private cloud) setup. It would not have been possible to expand their services in 90 countries across the world without using services from AWS like CloudFront.
Why AWS
MultiBank Group chose to launch their cloud journey with
Amazon Web Services (AWS) because of the resilient
global cloud infrastructure and services they provide to
customers by delivering the most robust security
requirements globally and providing customers the
ability to modernize their infrastructure that can
handle unexpected spikes in customer traffic to drive
business growth.
Moreover, technical leads at Multi Bank explored the
power of AWS's global edge network that can serve their
clients globally with more than 215 Edge locations in 90
cities across 47 countries and that was another great
advantage that can help the organization expand its
service as their business grows and evolves.
Why Zero&One
With a fully certified team of 50+ cloud engineers, Zero&One will be able to recommend the best practices for migration and take care of infrastructure monitoring end to end.
The Solution
Both teams had long discussions to assess and evaluate
the business and technical side of their current
infrastructure where they dove into short and long-term
goals and objectives to start building the roadmap on
how to move forward on their cloud journey. Following
that phase, a new AWS account was created for MultiBank
to help their staff discover the various services to
gain experience and confidence before building a plan
for the migration. During the migration process, Cloud
Endure was used to replicate the on-premises workloads
into a staging area in the sub-second range and then
utilized Amazon Elastic Compute Cloud (Amazon EC2)
Reserved Instances, Amazon Simple Storage Service
(Amazon S3) to store their static objects, Amazon
Relational Database Service (Amazon RDS) with Multi-AZ
to store the clients’ personal data in a highly
available managed database service that requires zero
maintenance efforts from MultiBank technical team thus
reducing the maintenance overhead drastically.
The network setup was one of the most important aspects
to serve the client’s requests where Amazon CloudFront
was utilized as the first point of contact for all
requests which then forwards the traffic for Amazon S3
buckets to serve static content and Elastic Load
Balancing to automatically distribute traffic across
multiple targets. At this stage, almost all resources
were successfully migrated to AWS, and then both teams
were able to migrate the core site of Multi Bank which
had the most significant load amongst all the production
applications with almost zero downtime and data loss.
Moreover, the Zero&One team helped MultiBank set up a
cloud-native and modernized solution on AWS that was
able to solve a critical problem they had on-premises
which is integrating all the production applications
their core CRM system by utilizing Amazon DynamoDB,
Amazon DynamoDB Stream, Amazon API Gateway, and AWS
Lambda.
Results and Benefits
Using AWS, MultiBank has improved the application
uptime, and page-load speed by serving static content
from Amazon CloudFront and automatically scale their
instances in a load-balanced environment using Amazon
EC2 Autoscaling to meet the customer’s demand without
the need to configure additional resources to the
running machines. MultiBank's digital transformation
enabled them to lead the financial industry by
constantly adding new features and enhancements to their
applications that allowed them to increase the number of
deployments by 300% compared to their on-premises
infrastructure.
This transition also had a positive impact on Multi Bank
developers and the IT team as both teams had more trust
in the robust environment, they had on AWS which allowed
them to innovate, and experiment with new cloud features
that can be easily utilized without having to worry
about maintaining the underlying infrastructure. In
addition, the modernized cloud-based solution on AWS was
able to synchronously share user and activity data in a
centralized CRM system eliminating the hassle of
manually exporting that data on a regular basis and
saving more time and effort compared to the on-premises
solution. Finally, MultiBank was able to cut costs by
55% using EC2 saving plans and Amazon EC2 Autoscaling.
