Cost efficiencies by migration to public cloud and using Digital Workers for DevOps

Executive Summary

DuploCloud was engaged with its strategic customer, a world’s leading supply chain risk management platform, to migrate their decade old IT infrastructure with a few TBs of data from a private data center to the AWS and Azure cloud. Their hosting costs were reduced from north of $1,000,000 per year to $250,000. DuploCloud successfully completed this project with under 19 hours of effective downtime and three weeks of efficient agile planning and mock drills.

The Challenge

The infrastructure was setup more than a decade ago. At a high level there were 2 main challenges:

“Most vendors took an infrastructure centric view, while migration challenges are fundamentally at the application layer. Their quotes to transform the app or even own the application migration aspects were prohibitive.”

DuploCloud Approach

The combination of our developer background, an experience of managing millions of VMs across the globe in Azure, and having gone through many of these migrations across various application stacks - our team has a playbook that instills confidence.

“The key to our approach is application first, infrastructure will be weaved by our bots.”

“We feed in an application topology and an infrastructure is auto-generated that is compliant with best practices. The results are compared with existing infrastructure for sanity.”

Data Migration

Main Glitch

We were most nervous about the data but that went all relatively smoothly with the exception of the SQL part and that was minor. After bringing the application live, we were realizing unexpected session timeouts. We discovered that the co-location Load balancer had some features that AWS LB did not seem to have. At first there was a bit of panic among the younger engineers, asking how we could have missed this. But then bouncing across classic, ALB and NLB with some IIS tweaks we settled down on ALB and resolved the issues.

“Our bots were very efficient as we kept asking for different infrastructure feature sets, further that was one area we did not have to worry about their human emotions as we kept asking for changes and working 48 hours straight. The whole DevOps and Security was basically a no-op here.”

In the next few days because of the changing IPs we had issues with some FTP issues with clients and we worked through that.

Savings Chart

About 1/3 of the savings came from operations offloaded to bots. Following table shows a comparison of on premise and Cloud offering that helped us realize majority of the capex savings here. Note that in public cloud we fundamentally don’t need to create an active DR site.

RESULT

Post Migration to AWS, the system cost reduced from more than $100,000+ to $20,000 dollars a month. The entire migration was completed within a weekend across global geographies with agile planning for three weeks. The automated bots from DuploCloud made server migration seamless. We enabled SOC2 certification and along with DevSecops services, DuploCloud is also assisting in data archiving of Salesforce data to Azure for the client enabling additional savings. DuploCloud is now the ‘Managed Service Provider’ for the customer’s AWS and Azure infrastructure.
