Choose the Right Architecture

Every modern business depends on technology to manage its operations, employees, accounts, inventory, production and customer information. As organizations grow, they need reliable IT infrastructure to operate ERP software, databases, business applications, file storage and reporting systems.

One important infrastructure decision is whether to operate applications using a local on-premise server or a cloud server. Both options can support business operations, but they differ in ownership, cost structure, maintenance, accessibility, scalability and disaster recovery.

For Bangladeshi businesses, the decision requires additional consideration. Internet reliability, electricity availability, generator and UPS capacity, hardware investment, IT team capability, data security and the location of factories or branch offices can all influence the right infrastructure model.

A small trading company may benefit from cloud hosting because it can avoid purchasing and maintaining physical servers. However, a large garments or textile factory operating ERP, production applications, barcode systems and machine integrations may require local infrastructure, cloud services or a combination of both.

This practical guide compares cloud and local servers, explains their advantages and limitations, examines business infrastructure costs in Bangladesh and provides a decision-making framework for selecting the right architecture.

Key recommendation: Do not select a server model only because it is modern or inexpensive. Evaluate the complete business requirement, application workload, connectivity, security, support capability and long-term total cost of ownership before making an investment.

1 Understanding Cloud Servers and Local On-Premise Servers

A server is a computer system that provides applications, data, services and resources to other computers or users over a network. Businesses use servers to operate ERP systems, databases, file sharing, email applications, websites, authentication services and reporting platforms.

What is a local or on-premise server?

A local server is physical server hardware installed and operated within an organization's own office, factory or data room. The organization purchases or leases the hardware and manages its operating system, storage, network, security, backup and maintenance.

For example, a garments factory may install a physical server in its IT room and host its ERP application, database, file services and internal reporting systems. Employees access these services through the factory's local area network.

  • Physical server hardware is installed at the organization's premises.
  • The company controls its hardware, storage and network configuration.
  • Internal applications can operate over the local network.
  • The organization is responsible for hardware maintenance and replacement.
  • Power, cooling, physical security and backup infrastructure must be managed.

What is a cloud server?

A cloud server is a virtual or physical computing resource provided through a cloud service provider. Instead of purchasing and maintaining the underlying server hardware, a business rents computing, storage and networking resources from the provider.

Cloud infrastructure can be hosted in a provider's data centre and accessed through the internet or a private network connection. Organizations can provision resources according to application requirements and adjust capacity as workloads change.

  • Server infrastructure is hosted in a cloud provider's data centre.
  • Businesses typically pay according to selected services and usage.
  • Resources can often be increased or reduced when required.
  • Remote users can access applications through approved connections.
  • The provider manages the underlying infrastructure, while the customer remains responsible for many application and security configurations.

Cloud vs local server: Basic comparison

Comparison Area Local Server Cloud Server
Infrastructure Installed at company premises. Hosted in a provider's data centre.
Ownership Company owns or leases hardware. Provider generally owns the infrastructure.
Initial Investment Usually higher hardware and setup investment. Can start with lower infrastructure investment.
Recurring Cost Maintenance, power, cooling and support. Subscription or usage-based charges.
Scalability May require additional hardware. Resources can often be scaled more quickly.
Internet Dependency Local applications can work over LAN. Remote access normally requires connectivity.
Maintenance Primarily managed by the company's IT team. Shared between provider and customer.
Disaster Recovery Requires a separate backup and recovery plan. Can use provider services and separate backup locations.

A cloud server is not automatically more secure or reliable than a local server. Both require proper configuration, monitoring, access control, patching and tested backup procedures.

2 Types of Cloud Computing: Public, Private and Hybrid Cloud

Cloud computing is not a single infrastructure model. Organizations can choose different cloud deployment models depending on their security requirements, application architecture, compliance obligations and operational needs.

Public cloud

Public cloud infrastructure is operated by a cloud service provider that offers computing, storage, networking and other services to multiple customers. Each customer's resources are logically isolated according to the provider's architecture and security controls.

  • Suitable for websites, business applications and scalable workloads.
  • Reduces the need to purchase physical server infrastructure.
  • Offers a wide range of managed services.
  • Requires careful configuration of access, networking and security.

Private cloud

A private cloud is an environment dedicated to a single organization. It may operate inside the company's own data centre or be hosted by a third-party provider.

  • Provides dedicated infrastructure or an isolated environment.
  • Allows greater control over architecture and resource allocation.
  • Can support specialized security and operational requirements.
  • May involve higher implementation and management costs.

Hybrid cloud

Hybrid cloud combines local infrastructure with cloud services. Applications and data can be distributed between the two environments according to performance, security, availability and business requirements.

For example, a manufacturing company may keep its factory ERP database and production applications on local servers while using cloud services for off-site backup, disaster recovery, email, collaboration and management reporting.

Cloud deployment model comparison

Model Infrastructure Typical Business Use
Public Cloud Shared provider infrastructure with logical isolation. Web applications, SaaS and scalable workloads.
Private Cloud Dedicated organizational environment. Specialized enterprise applications and controlled workloads.
Hybrid Cloud Combination of local and cloud infrastructure. Factory ERP, local applications and off-site backup.

Hybrid infrastructure is worth evaluating when a business needs fast local access to factory systems but also wants off-site backup, remote accessibility and cloud-based services.

3 Advantages and Disadvantages of Cloud Servers for Businesses

Cloud infrastructure can help businesses reduce hardware procurement responsibilities and deploy applications without building their own server rooms. However, the benefits depend on workload requirements, connectivity, provider selection and cost management.

Major advantages of cloud servers

  • Lower initial infrastructure investment: Businesses can avoid purchasing physical servers, storage systems and some supporting equipment.
  • Flexible resource allocation: CPU, RAM and storage can often be adjusted according to workload requirements.
  • Remote accessibility: Authorized employees can access business applications from different locations.
  • Faster deployment: New virtual servers and services can often be provisioned quickly.
  • Geographical redundancy options: Some providers offer multiple regions, availability zones and backup services.
  • Managed services: Databases, monitoring, security and backup services may reduce operational workloads.

Potential disadvantages of cloud servers

  • Recurring expenses: Monthly charges can increase with compute, storage, bandwidth and additional services.
  • Internet dependency: Poor connectivity can affect access to cloud-hosted applications.
  • Data transfer costs: Moving large volumes of data may create additional charges.
  • Provider dependency: Migration to another provider can require planning and technical effort.
  • Configuration responsibility: Incorrect access policies, exposed services and weak credentials can create security risks.
  • Service availability dependency: Outages at the provider or connectivity level may affect business operations.

When is a cloud server a good choice?

  • Small and medium-sized businesses with limited infrastructure budgets.
  • Organizations with multiple offices or remote employees.
  • Businesses using cloud-based ERP, CRM and accounting software.
  • Web applications and services with changing workloads.
  • Companies that need off-site backup and disaster recovery.

Before choosing cloud hosting, calculate the complete monthly cost, including server resources, storage, backup, bandwidth, security services, monitoring and any required software licences.

4 Advantages and Disadvantages of Local On-Premise Servers

Local server infrastructure remains important for organizations that require direct control over hardware, internal network performance, application integration and data management. It can be especially useful in manufacturing environments where multiple operational systems communicate over a factory network.

Major advantages of local servers

  • Direct infrastructure control: The organization can select hardware, operating systems, storage and network architecture.
  • Local network performance: Internal users can access locally hosted applications without depending on internet connectivity for every transaction.
  • Custom application integration: Local systems can integrate with production machines, barcode devices, RFID readers and other factory equipment.
  • Control over data location: The organization can determine where its primary data is physically stored.
  • Predictable hardware capacity: Properly sized infrastructure can provide consistent resources for known workloads.

Potential disadvantages of local servers

  • High initial investment in server hardware, storage and networking.
  • Additional expenditure for UPS, generator, cooling and physical security.
  • Requirement for skilled IT personnel to maintain the environment.
  • Hardware failures may interrupt services if redundancy is not designed.
  • Capacity expansion may require additional hardware procurement.
  • Off-site backup and disaster recovery require separate planning and investment.

When is a local server a good choice?

  • Garments and textile factories with intensive local production systems.
  • Organizations with stable and predictable workloads.
  • Businesses requiring direct integration with local machines and devices.
  • Companies with reliable IT teams and suitable server facilities.
  • Organizations that need local access during internet interruptions.

Owning a physical server does not automatically mean lower long-term costs. Include hardware depreciation, maintenance, power, cooling, licensing, backup, replacement and IT support in the financial evaluation.

5 Cloud vs Local Server Cost in Bangladesh: Initial Investment and Monthly Expenses

Cost is one of the most important factors when selecting infrastructure. However, comparing only the purchase price of a local server with the monthly price of a cloud virtual machine can lead to an incorrect decision.

Businesses should compare the total cost of ownership (TCO) over an appropriate period. This includes hardware, software, electricity, internet connectivity, maintenance, backup, security, support and future upgrades.

Local server infrastructure cost components

Cost Category Examples
Server Hardware Rack server, CPU, RAM, RAID storage and network cards.
Storage & Backup NAS, SAN, external backup storage and backup software.
Networking Switches, firewall, routers, cabling and network upgrades.
Power Infrastructure UPS, generator, power distribution and batteries.
Cooling & Facilities Air conditioning, server racks and physical security.
Software & Licensing Operating systems, virtualization, database and application licences.
Operations Maintenance, monitoring, IT personnel and hardware replacement.

Cloud server cost components

Cost Category Examples
Compute Virtual CPU, RAM and server instance charges.
Storage Disk capacity, snapshots and object storage.
Network Bandwidth, data transfer and network services.
Backup Backup storage, retention and recovery services.
Security Firewall, monitoring, encryption and security services.
Software Operating system, database and application licences.
Support Technical support plans and managed services.

Example: Compare the total cost of ownership

Consider a business evaluating a local server against a cloud-hosted environment for an ERP application. The following is a planning template, not a quotation or current Bangladesh market price.

Cost Element Local Server Cloud Server
Initial hardware investment Required Generally not required
Monthly infrastructure charges Power, cooling and maintenance Compute and storage billing
Backup infrastructure Separate storage and off-site copy Backup service and storage charges
Hardware replacement Company responsibility Underlying provider responsibility
Internet connectivity Required for remote access Required for application access
IT administration Company IT team Shared responsibility

How to calculate total cost of ownership

A simple infrastructure TCO model can be calculated as follows: 

Local Server TCO =
Initial Hardware Investment
+ Software and Licensing
+ Power and Cooling
+ Maintenance and Support
+ Backup and Disaster Recovery
+ Hardware Upgrades and Replacement

Cloud Server TCO =
Monthly Compute Charges
+ Storage Charges
+ Network and Data Transfer
+ Backup and Recovery Services
+ Security and Monitoring
+ Software Licensing
+ Technical Support

For a fair comparison, calculate both options over the same period, such as three or five years. Include expected growth, backup requirements, service availability and the cost of downtime.

Bangladesh-specific consideration: For local infrastructure, include electricity consumption, generator fuel, UPS battery replacement, cooling and physical server-room maintenance. For cloud infrastructure, evaluate internet connectivity, international bandwidth, data transfer charges and currency-related billing exposure.

Frequently Asked Questions

A cloud server runs on infrastructure provided by a cloud service provider and is accessed over a network or the internet. A local server, also called an on-premise server, is physically installed and managed at a company's own premises or data center. Cloud hosting generally reduces the need to purchase physical server hardware, while local servers provide more direct control over infrastructure, hardware and internal network operations.
Neither option is universally better. Cloud servers can be suitable for businesses that need remote access, flexible scalability and lower initial hardware investment. Local servers can be suitable for factories and organizations that require reliable access to applications over an internal LAN, direct infrastructure control and integration with local production systems. The right choice depends on business requirements, internet reliability, total ownership cost, security and IT management capabilities.
Cloud hosting usually requires less initial investment because businesses do not need to purchase physical server hardware, storage and related infrastructure. However, recurring monthly subscription, storage, bandwidth, backup and support charges can increase over time. A local server requires higher upfront investment, including hardware, UPS, cooling, networking and maintenance. Businesses should compare the total cost of ownership over three to five years instead of considering only the initial purchase price or monthly cloud fee.
Yes. Many ERP applications can run on cloud infrastructure, depending on their architecture, database, licensing and vendor requirements. Cloud-hosted ERP can support multiple branches, remote employees and management access from different locations. Before migration, evaluate application compatibility, database performance, internet connectivity, security, backup, integration requirements and the ERP vendor's support policy.
A local server can be advantageous for garments and textile factories where ERP, production monitoring, barcode scanning, RFID, MES and machine-related applications depend on fast internal network communication. It can also support local operations when the external internet connection is unavailable, provided the applications are designed to work within the local network. However, cloud services can still be useful for remote management, off-site backup, business intelligence and communication. A hybrid infrastructure may be appropriate for many factories.
A cloud-based ERP generally requires an internet connection to communicate with its hosted application and database. If the connection is unavailable, users may lose access until connectivity is restored, unless the ERP provides a supported offline mode. Businesses can reduce this risk through dual internet connections, automatic failover, reliable networking and appropriate continuity planning. Confirm offline capabilities with the ERP vendor before selecting a cloud solution.
Cloud servers are not automatically more secure than local servers. Security depends on configuration, access control, monitoring, patch management, encryption, backup and operational practices. Cloud providers may offer advanced security services, but customers remain responsible for securing their applications, user accounts and data according to the provider's shared responsibility model. Local servers require organizations to manage physical security, firewalls, operating system updates, access permissions and other security controls themselves.
Common disadvantages include recurring service costs, dependency on internet connectivity, possible latency, provider dependency and potential data transfer or storage charges. Businesses may also face migration complexity, service limitations and compliance considerations. These risks can be managed through proper provider selection, network redundancy, data backup, security configuration and a documented exit or recovery strategy.
Local servers require upfront investment in hardware, storage, networking, UPS, cooling and physical security. Organizations must also manage maintenance, operating system updates, hardware failures, backup, disaster recovery and technical support. Scaling capacity may require additional hardware purchases and installation. Without proper IT management, local infrastructure can become expensive, outdated and vulnerable to security risks.
Hybrid infrastructure combines local on-premise servers with cloud-based services. For example, a factory may run its ERP application and production systems on a local server while using cloud services for off-site backup, email, remote access and management dashboards. This approach can balance local operational requirements with cloud scalability and remote accessibility. However, proper integration, synchronization, security and disaster recovery planning are essential.
Server requirements depend on the number of concurrent users, applications, database size, transaction volume, reporting workload, virtualization and future business growth. A small application server may need significantly fewer resources than an ERP database server supporting hundreds of users. Evaluate CPU performance, RAM, storage capacity, SSD or NVMe performance, IOPS, network capacity and redundancy before purchasing hardware. Avoid selecting server specifications based only on user count.
Businesses should implement multi-factor authentication, strong access controls, endpoint protection, regular security updates, network segmentation and continuous monitoring. Maintain separate offline or immutable backups so ransomware cannot easily encrypt every backup copy. Restrict administrative privileges, secure remote access and regularly test data restoration. A documented incident response and disaster recovery plan is also important.
The 3-2-1 backup rule recommends maintaining at least three copies of important data, storing them on two different types of media, and keeping one copy off-site. For stronger ransomware protection, organizations can also maintain an immutable or offline backup. Backups should include databases, ERP application files, configurations and other critical business information. Regular restoration tests are necessary to confirm that backup data can actually be recovered.
RPO (Recovery Point Objective) defines how much data loss a business can tolerate, measured in time. For example, an RPO of one hour means the recovery strategy should aim to limit data loss to approximately one hour of transactions. RTO (Recovery Time Objective) defines how quickly a system must be restored after an outage. Both targets should be determined according to business impact, application criticality and recovery cost.
Yes, a properly designed local server environment can continue supporting applications that operate entirely within the factory or office LAN, even when the external internet connection is down. However, cloud-dependent applications, remote access, online services and integrations may stop working. The actual impact depends on application architecture, DNS configuration, network design and external service dependencies. Test this scenario before relying on local operations during an outage.
Begin by auditing existing servers, applications, databases, storage, network dependencies and business-critical processes. Identify application compatibility, migration risks, security requirements and expected costs. Select a suitable cloud provider, prepare the target environment, test application and database migration, and validate integrations and user access. Perform a controlled migration with verified backups, a rollback plan and post-migration performance monitoring. Involve ERP vendors and application owners throughout the process.
A cloud server may be suitable for a small or medium-sized business that wants to avoid large hardware investment and needs access from multiple locations. A local server may be appropriate when the business has stable internal network operations, specific application requirements or a need for direct infrastructure control. A hybrid model can combine local systems with cloud backup and remote services. Compare three-to-five-year costs, connectivity, security, support and business continuity before making the decision.
An IT manager should evaluate application and ERP requirements, concurrent users, CPU and RAM capacity, storage performance, network infrastructure, virtualization, high availability, backup, disaster recovery, security and future scalability. Also consider hardware warranty, vendor support, operating costs, electricity, UPS, generator capacity, cooling and physical security. Prepare a documented technical design and total cost of ownership comparison before procurement.
