The journey from On-premises to the Cloud

According to AWS, Cloud Migration is the process of moving applications, data, and IT infrastructure from physical servers or on-premise environments to a cloud computing platform. Instead of investing in, operating, and maintaining an entire server stack, businesses can utilize Cloud resources flexibly based on actual demand.

In operation, physical servers can face overloads, hardware failures, power outages, disk malfunctions, or data center disruptions. These incidents not only slow down systems but can also lead to data loss, affecting transactions and customer experience. Consequently, an increasing number of enterprises in Vietnam are seeking Enterprise Cloud Solutions to optimize IT infrastructure, reduce risks, and enhance scalability.

Why are On-premise systems prone to overload?

On-premise is a model where businesses host and manage physical servers at their own offices, private server rooms, or data centers. The company is responsible for investing in and operating all hardware, networking equipment, power, cooling, backups, and maintenance.

While this model may be suitable in the early stages, physical servers often become bottlenecks as the business grows, data increases rapidly, or the user base expands. Common causes include:

• Fixed resources: CPU, RAM, and storage capacity are limited by the purchased configuration.

• Scaling difficulties: When websites, ERP, CRM, or accounting systems experience traffic spikes, businesses cannot add resources instantly.

• High upgrade costs: Requires purchasing additional servers, networking gear, UPS, cooling systems, or licenses.

• Dependency on internal IT: The IT team must manually monitor, troubleshoot, backup, and maintain the system.

• Physical risks: Power outages, disk failures, hardware malfunctions, or server room incidents can disrupt operations.

The On-premise model may be suitable initially but is prone to overloading

For instance, a business might use the same server for ERP, CRM, and accounting software. At month-end, when multiple departments access the system simultaneously to process orders, generate reports, and verify data, the system may slow down or crash if the server lacks sufficient resources. In such cases, the issue is not just performance but the risk of disrupting the entire business workflow.

Benefits of flexible Scale up/down in the Cloud

Scale up involves increasing system resources such as CPU, RAM, or storage capacity. Scale down involves reducing resources when demand is lower. On the Cloud, adjusting resources is significantly more flexible than with physical servers.

The core strength of the Cloud is that businesses do not need to over-provision hardware just for peak periods. Whether launching a sales campaign, opening new branches, or deploying new software, resources can be expanded. When demand subsides, resources can be adjusted back to prevent waste.

Criteria	Physical Server	Cloud Hosting
Initial cost	High (Hardware investment)	Thấp hơn, trả theo tháng hoặc mức sử dụng
Scalability	Slow (Hardware dependent)	Linh hoạt, dễ tăng/giảm tài nguyên
Maintenance	Self-managed	Reduced operational burden
Cash flow	Large CapEx, long depreciation	Easy budget control (OpEx)
Hardware risk	Directly borne by business	Mitigated by specialized infrastructure

For Vietnamese enterprises, the Cloud helps optimize cash flow by eliminating the need for large investments in servers, server rooms, UPS, networking equipment, and cooling systems. IT costs shift from capital expenditure (CapEx) to flexible operational expenditure (OpEx). This is why enterprise cloud solutions are not just a technology choice but a strategy for sustainable growth.

What challenges cause downtime during data migration?

Downtime is the period when a system is disrupted, making it impossible to access or process transactions normally. For businesses, downtime results in lost revenue, negatively impacts customer experience, and puts immense pressure on operations teams.

Downtime is the period of disruption that impacts business systems

Cloud Migration offers many benefits, but without a proper plan, the migration process can introduce risks. Common issues include inadequate planning, failure to assess dependencies between applications and databases, lack of backups, Cloud misconfigurations, unstable connections, or insufficient testing before going live.

To minimize downtime, businesses should start by assessing their current IT infrastructure: identifying running systems, data locations, critical applications, and the ideal transition window. The migration plan should then be executed in phases, including data backups, execute migration to cloud, and a rollback plan in case of errors.

This approach ensures a safer transition to the Cloud, reducing disruptions and avoiding the "fix-after-migration" scenario.
