Intelitec Support & Infrastructure Services

Intelitec provides a range of consulting and support services relating to the IT infrastructure for any organisation. Our consultants work closely with the client to identify needs and to manage the implementation, training and monitoring processes for IT systems and networks.

Network & Communications Design
Intelitec infrastructure services can help your organisation communicate. With data and voice integration the possibilities are virtually limitless. The emergence of wireless and voice over IP standards have seen the introduction of truly cost effective equipment to help facilitate complex networks with relatively low investment. Multi-site organisations can also benefit from cost savings brought about by the use of public infrastructure with a secure virtual-private-network. Both wireless and bi-directional satellite availability means broadband benefits are available to the geographically dispersed organisation. For personnel on the ground, Intelitec Pacific builds mobile solutions deployed on popular pocket pc hardware, again leveraging wireless availability. Intelitec Pacific is gearing up now for the introduction of 1XRTT slated for release by mid-2003. Mobile staff can gain access to all corporate database information and applications from anywhere within the huge CDMA coverage area at speeds of up to 150kbps. We design both synchronization-based and live corporate data access solutions for PDA deployment with 802.11 wireless, GSM, GPRS, CDMA data and soon the mobile broadband - 1XRTT (CDMA2000).

Data Conversion
Many failed software integration projects have cited underestimation of data conversion requirements as a weak link. When a new or integrated component of a system's data is mapped, it is essential for software engineers to understand the meaning of the data, how it relates to the system objective and if indeed a data mapping is semantically correct. The risk to data integrity and downtime is often left hidden long after implementation. Specific and custom software required for data conversion and scrubbing should not be left out of the budget, this development lifecycle is very much a part of any system integration into a business process. Intelitec Pacific engineers call upon a depth of experience and a vast array of software modules to construct data conversion software and automated verification mechanisms in line with our common development methodology.

Intranet Implementation
The corporate intranet has quickly become one of the most important tools in the modern organisation. An intranet has many benefits. Firstly, it allows the organisation to centralise the operation of what can be many and varied information systems - it can be the ultimate convergence of all systems. All staff quickly become very familiar with the layout, navigation and operation of a well planned intranet. For document control, and workflow applications, an intranet connected to your messaging system is a powerful process optimisation tool. An intranet can also be very portable. Because corporate systems are accessed via a web browser, the intranet be be made accessible from outside the organisation to selected staff. Also the IT manager need not be concerned with maintaining the desktop environment to ensure compatibility with many different applications.

Testing/Verification Services & System Tuning
Enterprise information systems have become very complex. Often performance of operability concerns can arise long after the implementation. Intelitec can reassess how the software system is meeting the requirement and offer a range of solutions from system tuning and sizing to integration and extension.

Case Study
SME Server Suite Implementation

Client: National Registered Training Organisation
Requirement: Network and Server Infrastructure

A demand for complex hosting and server services, combined with the need to maintain fidelity in security and privacy has lead our client to implement an in-house server infrastructure capable of supporting the online needs of their business for many years.

Based on Windows 2000 Active Directory, the network and supporting services have been engineered to meet a modular yet cohesive set of requirements. Our client is now enjoying the benefits of server services capable of supporting complex messaging and workflow; online training delivery; extranet services; web mail; credit clearing facility and extensible database services.

Expansion into other regions and the growing number of mobile staff has prompted the design and implementation of virtual private networking services (see sidebar). A corporate intranet brings together much of the workflow functionality.

Case Study
SME Server Suite Implementation

Client: Local Business Cluster
Requirement: Shared infrastructure supporting mobile clients

Where a group of related companies need to share information and services, yet maintain security and privacy, Windows 2000 active directory has delivered. Network engineers have designed a system on AD where a number of services can be safely shared among a small group of companies. Group policy administration gave the design secure, robust and extremely fine grained control over user access.

Our client is also trialling Microsoft Mobile Information Server supporting a number of roaming staff. Synchronisation with key server information is affected quickly and securely from anywhere via GPRS. The design also features 802.11 wireless elements supporting seamless roaming from GPRS into the office wireless network.

The cluster also benefits from hosting internet services directly from the business premises. This has made possible hitherto unrealizable remote access to in-house services and information and allowed their clients access to ah-hoc queries and workflow functions.

Public Key Infrastructure

A Public Key Infrastructure (PKI) enables users of a basically unsecured public network such as the Internet to securely and privately exchange data and money through the use of a public and a private cryptographic key pair that is obtained and shared through a trusted authority. A public key infrastructure provides for digital certificates that can identify individuals or organisations and directory services that can store and, when necessary, revoke those certificates. Although the components of a PKI are generally standardised, a number of different vendor approaches and services are emerging. Typically they use a hierarchy of Certification Authorities (CAs). Often they use LDAP access to X.509 directories to implement this.

Virtual Private Networking

The essence of a Virtual Private Network (VPN) is its use of the Internet, Frame Relay or ATM networks as a Wide Area Network (WAN) backbone to supplement or replace the costly long-distance leased and dial-up links in a traditional private network. Sending private information via these new public networks either domestically or internationally is similar to using the Public Switched Telephone Network (PSTN) for internal communications, or sending confidential correspondence by mail. Enterprises can benefit tremendously by using these new, more advanced public networks, which are operated and managed by Internet Service Providers (ISPs) and carriers.

The primary motivation of the distributed enterprise when implementing a VPN is cost saving. Gartner Group expects VPNs to offer a savings of at least 50% for remote access and, owing to this substantial savings, 70% of Fortune 500 companies will use VPNs for remote access by 2003. Forrester Research found 60% savings when comparing private and virtual private solutions for a 2000-user remote LAN access network.

Security is often cited as the primary concern regarding VPNs. By taking the necessary precautions, however, a VPN can be made just as secure as any private network, and even more secure than most. The foundation of VPN security is the firewall. A firewall passes only authorized traffic for all trusted users, and blocks everything else. In other words, all unknown or un-trusted users are denied access, and the two-way traffic of trusted users is screened to ensure it is expressly permitted.
