SAP Migration & Resilience Initiative

Customer Overview

The customer is one of Thailand’s top Manufacturing, operating a 100‑million‑litre plant, supplying 400+ nationwide colour‑shop dealers, and employing more than 1,000 staff. Its 2024‑26 growth strategy targets a > THB 15 billion revenue goal and the country’s #1 market‑share position—objectives that demand always‑on digital operations.

Business Challenge

After moving SAP ECC, analytics databases, and a dealer‑ordering portal to a domestic private‑cloud, the company experienced frequent hardware and hypervisor failures that caused three‑to‑four production‑stopping outages per quarter. Continued downtime risked peak‑season sales, delayed shipments, and threatened its aggressive growth plan.

Partner Solution — What Was Built and How

SiS Distribution designed an enterprise‑grade foundation on AWS, beginning with a multi‑account landing zone created through AWS Organizations. Separate accounts were carved out for Shared‑Services, SAP production, non‑SAP production, development / test, logging‑archive, and audit. Centralised sign‑on is handled by AWS IAM Identity Center federated to Azure AD, while Service Control Policies fence off each environment with least‑privilege boundaries.
A hub‑and‑spoke network anchors the design. The hub VPC in the Shared‑Services account attaches to an AWS Transit Gateway that routes traffic among spoke VPCs and to the customer’s Bangkok headquarters. Primary on‑premises connectivity runs over a dedicated AWS Direct Connect circuit; an IPSec Site‑to‑Site VPN on a separate fibre serves as automatic fail‑over. Outbound Internet access is tightly controlled: NAT Gateways and a single Internet Gateway live only in the hub, keeping every application subnet private.
For the core ERP landscape, SiS re‑platformed SAP ECC 6 on HANA with HANA System Replication across two Availability Zones. The database runs on r6i EC2 instances backed by high‑performance EBS gp3 Block Express volumes. Encrypted backups flow directly to Amazon S3 via SAP Backint, eliminating tape libraries and secondary storage appliances.
Non‑SAP workloads—including analytics databases and a dealer‑ordering portal—were lifted almost in real time with AWS Application Migration Service into their own production VPC. Remaining Linux and Windows servers now run in EC2 auto‑recovery groups, gaining instance‑level self‑healing without manual intervention.
Operational visibility is unified across every account: Amazon CloudWatch metrics and AWS CloudTrail logs stream to an immutable bucket in the Logging‑Archive account, AWS Systems Manager orchestrates patching and run‑command automation, and the Audit account leverages AWS Security Hub to score continuous compliance against CIS benchmarks. Taken together, this architecture delivers the multi‑AZ availability, enterprise governance, and elastic scalability that the previous private‑cloud platform could not provide.

Results & Benefits — Business Impact Achieved

The move to AWS transformed reliability. In the first six months after migration, ERP, analytics, and dealer‑ordering workloads achieved 99.98 % uptime, eliminating the three‑to‑four unplanned outages per quarter that once halted factory lines and delayed colour‑shop orders.
Cost efficiency improved just as dramatically. Right‑sizing EC2 instances, taking advantage of on‑demand scaling, and retiring private‑cloud fees together cut the platform’s projected five‑year total cost of ownership by 31 %. Backup economics also shifted: by streaming encrypted copies straight to Amazon S3 and lifecycle‑tiering them to S3 Glacier Flexible Retrieval, the company trimmed backup storage spend by roughly 65 %.
Speed of innovation climbed as well. Spinning up a fresh development or test VPC from landing‑zone templates now takes less than two hours—a 90 % reduction versus the four‑to‑five days previously required. Freed from constant firefighting and lengthy environment builds, the IT team can focus on higher‑value analytics initiatives and mobile enhancements that support the company’s aggressive 2024–26 growth goals.
