Cloud, Server, Mail and Hosting for Businesses
IT Systems designs and operates cloud infrastructure for businesses based on real workloads: websites, internal applications, business email, servers, backup, security, monitoring and technical support. The goal is to choose the right configuration, prepare recovery options and assign clear operational responsibility.
Cloud/VPS
Virtual servers for websites, apps and ERP workloads.
Hosting
WordPress hosting, SSL, backup and performance tuning.
Mail & Backup
Business email by domain and data backup.
Quick selection summary
Not every business needs a Cloud Server from the beginning. A small website may run well on managed hosting; internal applications or highly customized websites usually need VPS/Cloud Server; important data should have a separate backup plan.
| Situation | Recommended option | Not ideal when | What IT Systems handles |
|---|---|---|---|
| Company website, landing page or basic WordPress site | Business hosting | You need custom services, root access or a special workload. | Select hosting, SSL, cache, backup, website migration and issue handling. |
| Plugin-heavy website, small ecommerce site or staging environment | Low to mid-range VPS/Cloud Server | There is no server administrator or no backup plan. | Install web server, database, firewall, SSL, monitoring and backup. |
| Odoo, n8n, CRM, internal app or separate database | Cloud Server sized by workload | You choose only by cheap price without checking CPU/RAM/IOPS. | Assess workload, design sizing, deploy and operate the server. |
| Domain email with optimized cost | Email Hosting | You need advanced cloud collaboration, Office desktop, Teams or Drive features. | Create mailboxes, configure DNS, anti-spam and Outlook/mobile setup. |
| Data must be recoverable after incidents | Cloud Backup | Backups are stored only on the same main server or hosting account. | Design backup schedule, storage location, access rules and restore testing. |
Services in the Cloud cluster
Cloud Server / VPS
CPU, RAM, SSD/NVMe, operating system, firewall, backup, monitoring and managed operation for websites, applications and databases.
Hosting WordPress
Hosting for company websites with SSL, cache, backup, speed optimization and coordination with website management work.
Email Hosting
Domain-based email, mailbox, webmail/IMAP/SMTP, anti-spam and SPF/DKIM/DMARC configuration.
Backup Cloud
Scheduled backup for websites, databases, servers, email or important files, with restore testing when needed.
Pre-quotation assessment checklist
| Information group | What to provide | Impact on quotation |
|---|---|---|
| Website/application | Platform, source code, database, traffic, plugins and number of users. | Determines hosting vs VPS/cloud server and CPU/RAM resources. |
| Data | File/database/email size, change frequency and business-critical data. | Determines storage size, backup, retention and restore cost. |
| Performance | Current speed, peak hours, request volume, timeout errors and current CPU/RAM usage. | Avoids undersized systems that bottleneck or oversized systems that waste budget. |
| Security | SSL, firewall, admin rights, allowed IPs, plugin/theme status and user accounts. | Defines hardening, monitoring and access-control scope. |
| Operational SLA | Support hours, expected response time and acceptable downtime. | Directly affects managed service scope and support cost. |
Reference price ranges and how to read pricing
Market prices should only be used for budget planning. Two packages with the same CPU/RAM can still differ in IOPS, backup, datacenter, network quality, support level and management scope.
| Service group | Reference market range | Questions to ask before buying |
|---|---|---|
| Entry VPS | About 79,000 - 228,000 VND/month for low configurations depending on billing cycle. | Is backup included, SSD/NVMe storage, bandwidth, IP and support when errors happen? |
| Business Cloud Server | From several hundred thousand to several million VND/month depending on CPU/RAM/SSD/SLA. | HA, storage, IOPS, snapshot, firewall, uptime and migration support. |
| Business Hosting | About 239,000 - 840,000 VND/month for business hosting plans. | CPU/RAM resources, number of websites, backup, LiteSpeed/cache, malware support and restore policy. |
| Email Hosting | Usually priced by mailbox, storage and anti-spam requirements. | Mailbox quota, SMTP limits, spam filtering, DNS support and migration scope. |
Common risks when choosing the wrong infrastructure
Cheap VPS without independent backup
Disk failure, malware or human error can lead to data loss if there is no separate backup copy.
Weak hosting for plugin-heavy websites
WordPress can become slow, return 503/timeout errors, make admin work difficult and waste ad budget when landing pages load slowly.
Incomplete email DNS configuration
Missing SPF, DKIM or DMARC makes email more likely to land in spam or allows domain spoofing risk.
No server administrator
A server may run on day one, but risk increases when there is no patching, monitoring or log review process.
IT Systems implementation process
1. Assessment
Review the current system, usage goals, data, traffic load, budget and SLA requirements.
2. Design
Recommend hosting, VPS, cloud, email or backup options, resource sizing, operating model and migration plan.
3. Implementation
Set up server, hosting or email, configure DNS/SSL/firewall/backup, migrate data and test the environment.
4. Operation
Handover documentation, monitor resources, handle incidents, apply security updates and recommend upgrades.
FAQ: Cloud, Server, Mail and Hosting
Should we choose hosting or VPS?
Hosting fits websites that need simple management. VPS fits when you need dedicated resources, custom installation or a separate application environment.
How is Cloud Server different from cheap VPS?
Cloud Server usually focuses more on resilient infrastructure, better storage, backup and scalability; cheap VPS is suitable for light workloads and lower budgets.
Can IT Systems manage the service after rental?
Yes. IT Systems can combine cloud services with IT Support, website management, security, backup and user support.
Can old websites, servers or email be migrated?
Yes. IT Systems reviews data, DNS, cutover timing, backup and rollback before migration to reduce disruption.
Need to choose cloud, server, mail or hosting?
IT Systems reviews your website, application, email, data, traffic load and budget to recommend a suitable configuration, avoiding underbuying or overspending.
