What is VPS service? Learn how to administer VPS effectively

VPS (Virtual Private Server) is a form of virtual server created by the method of dividing a physical server into many different servers with features similar to a dedicated server, running in the form of resource sharing from that original physical server.

What is VPS?

VPS (Virtual Private Server) is a form of virtual server

Today VPS services are widely used in businesses and small business models. But usually VPS is used for the following needs:

– Game server (game server).

– Hosting multi-service websites (sales websites, e-commerce websites, forums, websites with high traffic …)

– Platform development.

– Server for enterprise email systems.

– Run media programs directly.

– Create virtual environments for programming, virus analysis, research, etc.

– Store data: documents, images, videos, etc

Compare VPS and Cloud server

  • Convenient in management

When comparing VPS and Cloud server, we see that the common VPS services mostly provide customers with admin account or root for remote access. For tasks such as booting, backing up, reinstalling the OS, the customer must send a request to the service provider.

On the VPS cloud, customers are provided with a portal account, customers can actively start, shut down, backup, reinstall the OS from the local image or available on the system. Customers will be proactive in every situation.

  • Flexible scalability

When comparing VPS and Cloud server, we see that ordinary VPS is hosted on a separate server, when customers want to upgrade VPS, if that server still has resources, it’s okay, but if the server is running out of resources reserve, the upgrade will interrupt VPS for a period of time, though not much.

As for the VPS cloud, reserve resources are plenty and always ready to upgrade VPS, the allocation is also very fast.

With superior features, the provision of VPS cloud services is the current trend of the providers and also the choice of customers.

  • High security

VPS is usually deployed on physical servers, so if there is a problem with this server, the VPS will be affected. So what happens when the physical space has a problem? At that time, the risk of equipment failure leading to your data loss is very high. Meanwhile, if using the Backup mechanism for VPS, the cost is not cheap and not all IDC providers support you.

VPS is usually deployed on physical servers

For VPS cloud, the VPS is hosted on a system of many physical servers, but that server has a problem, the VPS is automatically transferred to the host on another computer in the system. This ensures availability for VPS.

  • Cost savings

Using VPS, the scalability is very limited due to dependence on physical VPS, while with Cloud VPS, you only pay the cost for the parameters you need (HDD, RAM, Capacity …). Easy upgrade/downgrade (when demand drops) will help you save a lot on service costs.

Guide to administering VPS effectively

  • Ping

From your computer: type: ping -t in cmd

Your computer will check the connection to the VPS to see if the connection to the VPS is guaranteed to connect. With a normal network connection, the ping will be about 70 ~ 90 ms.

  • Check uptime

Like the time the server operates continuously, you check the VPS time from the time of delivery to the time of checking. If it is larger than the uptime, you should report it

Use the command: # uptime

  • Check the hard drive writing speed

Use the command: # dd if = / dev / zero of = 1GB.tmp bs = 1024 count = 1M conv = fdatasync

The result will tell you how long it takes to copy 1G of data to the hard drive and the speed of copying (> 50Mb / s is good,> 100Mb / s is very good )

Check hard drive capacity

  • Use the command: # df -h
  • Check the amount of RAM

Use the command: free -m

The “Total” column will tell you the total amount of RAM you have (including the extra RAM).

The used column will indicate the amount of RAM you have used and the free column will show the remaining RAM.

VPS is working well is the amount of RAM consumption reaches from 1/2 to 2/3 of the actual RAM. If the amount of RAM used is more than 3/4 and can reach the limit of RAM, we recommend that you also upgrade the VPS package because RAM determines the ability to maintain the operation, if the amount of RAM is exhausted, it will cause VPS overload status.

With just a few basic operations, you can manage your VPS effectively at home or work. In other cases, you can contact the service provider directly for the best VPS management support.
