There is a common requirement to migrate datacenter from on-premises to cloud.

During my consulting career, I led several on-premises datacenter migrations. Additionally, these projects targeted financial, utilities, and transportation organizations.

To give you a big-picture view, I outline the datacenter structure.

The datacenter structure includes racks, power bus, cooling towers, networking gear, air handling units, backup generation, and water storage. This layout supports power distribution, environmental control, and resilience. Understanding how these elements interact helps operators plan capacity and respond to changes.

Within each rack, components such as network switches, cable management, servers, and cooling modules exist...

I would like to provide a data architecture summary briefly. Additionally, it reflects my long-term working practices in this area.

Data Architecture and Governance:

• Data governance involves strategies, policies, processes and procedures, collaboration, tools, audit and metrics, etc. For detail info, please refer to Seven Steps to Effective Data Governance.
• Data quality includes data validation, foreign keys, constraints and data cleansing. Please refer to 10 Best Practices in Database Schema Design.
• Metadata management involves schema design, data linage, API contracts, etc. Building a Database-driven Application Framework includes good references.
• Toolbox: MS Purview, Ataccama, Denodo

One of my clients is moving its SAP on-premise instances to the cloud. SAP offers Near Zero Downtime Technology (NZDT) to reduce the migration downtime from approx. one week to 6-60 hours (from 6pm Friday to 6am Monday). The purpose of applying NZDT is to secure business continuity. However, it’s not cheap, to pay a million-dollar bill for a weekend! If you know how, then the estimation of building your own in-house developed NZDT component should be less than 50K.

Please be aware, NZDT is neither a new technology, nor the invention of SAP. The discussion of how to implement it is all over the place on the internet. Our Architects have gained enough experience in this area during the past two decades. We have designed and developed sophisticated non-stop 24*7 data replication tool Live...
