Security Level
A data center can only be considered reliable if it ensures a high level of security. To achieve this, the facility’s management must implement strict access controls, 24/7 security, multi-level authentication, video surveillance in server areas, and other protective measures. For user convenience, data centers are classified based on their reliability level.
There are four tiers—TIER I, II, III, and IV. The higher the tier, the more secure the data center.
For maximum safety, it’s best to choose Tier III or IV centers, as they guarantee high reliability for both hardware and network infrastructure.
Location
The server should ideally be located in the same region as the majority of the project’s users. For websites targeting a Russian audience, it’s best to select data centers within Russia to ensure optimal connection speeds. If the server is located far away (e.g., in the USA), users may experience slower loading times due to multiple intermediate network nodes.
Additionally, the physical placement of the data center matters. Avoid facilities in basements, bunkers, or bomb shelters, as they may face flooding or sudden eviction by authorities. Office buildings are also not ideal—the best option is a standalone industrial facility designed specifically for data centers.
Uptime
Uptime refers to the uninterrupted operation time of a server since its launch, measured as a percentage. To calculate it, subtract the total downtime from 100%. Downtime can be caused by:
- Software failures
- Hardware malfunctions
- Cooling system issues
- Power supply disruptions
- Network outages
- DDoS attacks
Since no data center is completely immune to these risks, 100% uptime is impossible. However, a reliable facility should maintain at least 98% uptime.
Technical Specifications
A data center must be equipped with essential systems to ensure smooth operations, including:
- Uninterruptible power supply (UPS)
- Backup generators
- Advanced cooling systems
- Climate control (temperature & humidity regulation)
- Fire detection & suppression (e.g., gas-based systems)
- Dust-free, sealed server rooms
Technical Staff Expertise
The competence of the data center’s technicians is crucial. They must be skilled professionals capable of quickly and effectively resolving technical issues. The quality of their work directly impacts server stability and, consequently, the performance of hosted projects.
Additional Considerations
When selecting a data center, also evaluate:
- Service offerings & pricing
- Customer support quality
- User reviews
- Other relevant criteria
