What are the differences between cloud servers and on-premise (physical) servers?
The following are some of the differences and comparisons between cloud servers and on-premise (physical) servers:
| Cloud Server Features | |
| Safety | - The hardware infrastructure (servers/network) is built in as standard, so there is little service interruption due to hardware failure |
| Operational aspect | - You can quickly build servers, add more servers, and upgrade their specifications regardless of the server location
- The server can be scaled out to accommodate high loads of access |
| Price | - Most cloud services charge a per-data-transfer amount, so monthly costs fluctuate
- Overseas cloud services such as AWS, Google Cloud (GCP), Azure, and Oracle Cloud have service usage fees that fluctuate depending on the monthly exchange rate |
| merit | - Resources can be added easily, as much as needed, when needed
- Even if the server configuration is minimal when the cloud is introduced, it is possible to upgrade or downgrade the specifications after the service starts |
| Disadvantages | - Because the hardware infrastructure and configuration are black boxes, it is difficult to identify the cause of hardware-related failures and to evaluate performance
- Data transfer is charged as you go, so monthly service fees may increase |
| comprehensive evaluation | - For web services and systems where the access load to the server changes suddenly, such as games, apps, e-commerce sites, media sites, and digital content, the cloud is suitable as it can quickly respond to adding resources and scaling out
- In terms of cloud reliability, most cloud services undergo annual audits by internationally accredited third-party auditing organizations to provide assurance about security, privacy, and compliance controls |
| On-premise (physical server) features | |
| Safety | - Since the data is stored in a physical environment, the location of the server is clear |
| Operational aspect | - Machine resources such as servers, firewalls, and load balancers can be exclusively used by one company, making it easy to customize the system to suit your company's requirements |
| Price | Although initial implementation costs are incurred, monthly costs are often fixed, making monthly cost management stable. However, there are indirect, invisible personnel costs involved, such as infrastructure maintenance man-hours, data center rack costs, electricity costs, and hardware manufacturer maintenance renewals |
| merit | ・Since it is exclusive to one company, it is not affected by other users' systems. ・The performance of the machine and resources, such as CPU/memory, is clear. |
| Disadvantages | ・There is a risk of server shutdown due to physical hardware failure. ・It is difficult to upgrade hardware resources. ・When initially introducing hardware, it takes time to size and estimate the system. |
| comprehensive evaluation | - Because it allows you to make maximum use of server machine/hardware resources, when developing mission-critical systems that do not use the external Internet, physical servers can maintain stable, high performance rather than the cloud
- Some studies have shown that performance evaluations compared to cloud services have shown that performance results are more than three times faster |
*Beyond can provide server operation, maintenance, and monitoring (24 hours a day, 365 days a year) even for on-premise (physical server) infrastructure environments
In addition, for the design and construction of on-premise (physical server) infrastructure environments and on-site support, we will work in collaboration with Beyond's infrastructure partners
● Cloud server design and construction
● Cloud server migration
● AWS cloud integration
