Server implementations
Servers are the most business-critical part of an information system, providing information system services to a wide range of users. That is why it is difficult to over-estimate the need to make right decisions already when planning the system and drawing up its architecture. Even with seemingly simple information system services, there are so many contact points with other systems that the operational ability of one system might determine the availability of dozens of services. Often, the following rule applies – the easier a service seems to be, the more critical it is to have it functioning properly for an information system as a whole.
Basic services
Even small low-performance network devices, meant for home use, can provide basic services such as DHCP and DNS. The availability and escalating abilities of these services are important in the installation network, in order to guarantee the availability of any other information system service to the users. Furthermore, the correct configuration of these services is important to guarantee the network’s security. Those who wish to start using new network address standard IPv6, must learn what is the role of DHCP in this network which functions mainly on auto-configuration principle.
User identification
Microsoft Active Directory (AD), functioning on LDAP technology, is the main user identification system supported by Net Group. In brief, AD is a user rights system which enables to regulate user access to information services like e-mail, document management system and network catalogue. Microsoft has built a whole user work environment management system around AD. This helps to regulate the times for user access to an information system, determine the installation of certain software packages on the user’s computer, and the availability of certain printers and network catalogues to the user. What is more, AD configuration determines the construction of network catalogue service (file server) in a way for the documents to be accessible from any location.
Collaboration server
Net Group implements and manages collaboration solutions based mainly on Microsoft Exchange/Outlook and IBM Lotus Domino/Notes software. When many managers deem the collaboration services (e-mail, calendar, contact list) not to be very business-critical, collaboration server failure is the first to be noticed by a user. When this failure occurs, the internal communication of an installation is paralysed in an instant, as is communication with external partners. The availability and security of a collaboration server is critical at a time of most offers, agreements and contracts being made and signed electronically. The experience and skills of Net Group to connect collaboration systems to telephone systems and messaging (Lync, Office Communications Server) create a functioning and well-run environment where business can really take place at the speed of light.
Database server
The critical importance of database servers for business process is understood by most business decision-makers. A rank-and-file specialist’s skills might not be enough to draw up the architecture of this database server which would provide smooth service for users even when the server is heavily loaded.Net Group is uniquely experienced in optimising database systems. Net Group’s software development division can determine drawbacks in the system logic which might inhibit the functioning of a database when it is heavily loaded. In turn, IT infrastructure division specialists can configure the database server and create hardware architecture which is able to provide high-quality service even when the server is heavily loaded. We are also skilled in creating a shadow copy of the database which enables the database to be restored at any time when a failure has occurred.
