Until now, many companies use only the traditional desktop PC as the only possible means of work. But there is another way to carry out effective work of employees, and at the same time to reduce the total cost of ownership and support of information systems. This method - using of thin clients.
Thin client is an input device and information display (Terminal). Typically, a thin client - a compact and silent computer without a hard drive (without fans), loading the main operating system which occurs on the server, but we also offer a thin client configuration with SSD hard drive, it can be used as a normal PC. All custom applications are running on a terminal server (application server). Since all the computational burden placed on the server, thin client has a minimum hardware configuration without sacrificing performance and, accordingly, a low price.
Let's try to compare the two approaches
A typical approach: using a desktop PC
- Long and complicated installation;
- High costs of maintenance and technical support, especially for remote offices;
- The need for constant upgrades of systems and software installed at each workplace;
- Ability to uncontrolled user activities (playing games and other "Unofficial" activities);
- The complexity of the backup critical data;
- Sensitive data can easily be copied to external media and made out of the office;
- Each PC - a potential "hole" for infection by viruses of the information system;
- Every 3 years recommended renewal of the PC;
A new approach: using a thin clients
- Installation is simple, you just need to make connecting to the network;
- No local settings or copy data to your hard drive;
- Fully centralized management;
- All data and applications are stored centrally - increased security, backups are easy to organize;
- All hardware and software upgrades are made only on the server, client systems do not require upgrading;
- Thin clients are not likely to be infected by viruses;
- Thin client is not an independent computer in itself, is of no value as an object of theft;
- The average lifespan of a thin client is 5-7 years;
So, summing up, we can provide a list of the main differences and advantages of using thin clients instead of conventional PCs.
- Working on a standard PC, office workers use 10-20% of PCs capability and its cost. The company loses 80% -90% of the money invested
- Reduction of the initial purchase cost, because thin client have the minimum configuration requirements;
- Significant reduction in energy use - a typical thin client has a power consumption from 10-25 watts (compared to 250-350 watts for a PC)
- Ease of implementation of tasks - no need to configure each computer separately, there is a centralized management of clients. All settings for managing thin-client system administrator performs centralized on the server;
- Saving system administrator’s time, serving exactly the same computers, the likelihood of damage which is reduced to a minimum, and all the programs installed on the server;
- Scalability - once created a system image for the entire group of users you can easily maintain a scalable network. You can install so many jobs as you want, the addition of new jobs require minimal effort;
- Security and fault tolerance. When terminal is loading, it gets the operating system "from manufacturer". All user information stored on the server on RAID-array, and is regularly backing up, which increases fault tolerance;
- Protection from leaks of information - no local drives - you can’t make copies of documents on removable storage media (unless otherwise permitted by the system administrator).
- The rate of work. Terminal access is different in that the thin client is transmitted only picture from the screen, while a personal computer can transfer a large amounts of data. A good example of such programs is 1C. When the server and the client part 1C is located on the same machine, then there is no transfer of the database on a network, and 1C programs run much faster.
