The Technical "Know-How"
Server Tier - The Font Tier
Our Server definition:
The term server is used to express a number of concepts. We view "Server"
as a hardware or software entity which services other computers, programs,
users, clients or even other servers. The following are servers:
Web (HTTP), Proxy, FTP, Mail, File, Application, Database, SQL, ..etc.
The actual computer hardware, but your mobile device can also function as
a server. My laptop may run a number of servers and act as a physical server
(hardware and software) also.
A virtual server may act as an independent hardware server, but in reality
it is Zeros and Ones.
The real benefits behind servers is that a server works as an independent
entity and may have several dynamic functionality or services. Servers can
be added or removed with ease and have several functionalities. For
example, a web server may also be an application server and database
server. An FTP server can be used as a remote buffer or a remote file server.
Managing servers and their communication may need the following:
• Need to manage servers
• Check to see there is no network problems
• Check client's connection
• Check network connectivity
• Test the communication between the client and server
• Must first enable the server Access log before you can view the log.
• View server Access log
• Network issues include the firewall blocking access, or networks not connecting to each other
Security and Proxy Server:
Proxy server is a mediator server between client and the internet. Proxy servers
conceal and make your network id anonymous by hiding your IP
address. Proxy servers offers basic functionalities such as firewall and network
data filtering, network connection sharing plus data caching.
Proxy server may include Authentication, Authorization and Assurance (security attributes).
Loosely Coupling and Servers:
Servers are ideal for architecting system with tiers, loosely
coupled components, components structure , independent services and software engines.
