  • IT Infrastructure Build

    Most businesses depend on software applications which in turn depends on the network infrastructure foundation that supports them. It is extremely important to have a reliable and secure network infrastructure so you can focus on running your business. Some technology firms implement networks using residential-grade networking solutions which often lead to unstable networks, poor performance and less return on investment. Ostec builds networks using enterprise-class solutions and solid design principles. This results in higher performance, more stability and a better long-term return on investment.

    Local Area Network (LAN) Infrastructure

    Whether your LAN is comprised of a few PC’s in a small office or a large campus network of interconnected buildings supporting thousands of devices, Ostec has the experience to build and support LAN’s using the latest switch and cabling technologies. Ostec’s focus on networking allows us to provide extensive specialized experience in LAN technologies often not available from general-purpose IT firms. Examples of technologies available in enterprise-class LAN’s such as those deployed by Ostec include:

    • Virtual Local Area Network (VLAN)
    • Fiber optic Campus Area Network (CAN)
    • High availability switch redundancy
    • Fiber or wireless Metro Area Network (MAN)
    • Proper multilayer network design
    • High performance layer-3 switching
    • Wide Area Network (WAN) Infrastructure


    From small WAN’s of a couple of linked sites up to vast implementations of hundreds of sites, Ostec knows how to build and support enterprise WAN’s using the latest communication and technologies. Our extensive experience with many telecommunication carrier companies covers a wide variety of technologies including:

    • Virtual Private Network (VPN) Technologies


    Enabling secure stable communications across untrusted networks such as the Internet has become commonplace. VPN’s serve as a secure and very cost effective way of linking sites or allowing secure remote access to a network from anywhere. Using the latest encryption and authentication technologies, Ostec often builds and supports enterprises with VPN-linked remote sites all over the world. Ostec has extensive experience with many kinds of VPN including:

    • IPSEC site-to-site VPN’s for inexpensive WAN’s
    • IPSEC remote access
    • SSL clientless remote access
    • SSL client-based remote access

    Many organizations have yet to realize 21st century network security realities. Ostec builds secure networks, secures existing networks and conducts network security assessments. We analyze networks for security issues, help fix them and show customers how to maintain solid and secure networks. Network security, a subset of information security, can be a challenge for most enterprises. Ostec has extensive experience with many areas of network security including:

    • Network Intrusion Detection / Prevention Systems (IDS/IPS)
    • Firewall and VPN
    • Network Security Assessment (NSA)
    • Email filtering

    Benefits of a Data Centre to your Company

    Most small to medium sized business owners keep their server and other IT equipment on a shelf in the corner of the office or perhaps locked in the stationery cupboard. They might have it connected to a UPS (Uninterruptible Power Supply) so when power goes down the server will still keep on working. Also internet connection is a mission critical tool for most businesses so what do you do if the line goes down? You can have more than one line provided by different providers or have a mobile 3G backup though that is probably not going to be fast enough for your needs.

    What you can do is keep your important server or servers off site at a data centre. This has some major benefits:

    • A data center is essentially a computer room – a physical facility that allows you to store and manage your servers, networks and other computer equipment in a controlled environment
    • A data center is a building or premise that houses the central data processing equipment (i.e. servers and infrastructure required for operation) of one or several companies or organizations. The data center must consist of at least one separate room featuring independent power supply and climate control
    • The data center is the core of a company; it creates the technical and infrastructural conditions required for virtually all business processes in a company. It secures the installed servers and components in use, protects them from external dangers and provides the infrastructure required for continued reliable operation. The physical structure provides protection against unauthorized access, fire and natural disasters. The necessary power supply and climate control ensure reliability.


    Data Centre Developing Process:

    The first and most important step in constructing a data center is design planning. Our critical environment experts at Ostec will work with you to ensure peak performance and reliability of your data center before the first concrete is poured. Proper design for data center planning requires a thorough understanding of your specific operation, support equipment, objectives and needs today and into the future. With decades of experience, Ostec ensures maximum reliability and efficiency of each data center we design and build.

    Data Centre Design

    Our approach to every engagement starts with defining and understanding the project requirements for the data center and identifying the business objectives. This is followed by an assessment and audit of the available assets and inevitable detriments. We then establish the design criteria and create a preliminary design to summarize the associated project build costs.

    Our team of architects, consultants and mechanical and electrical engineers will work closely with you to create a design that provides a cost-effective and energy-efficient solution.

    Data Centre Build

    Once the design for the data center is complete, Ostec will manage the entire project to ensure it is completed on time and on budget. Ostec maintains relationships with ‘best-of-breed’, critical infrastructure suppliers, local architect/engineers and construction partners. This ensures you receive the best possible equipment cost, with the most favorable delivery terms and have it installed by the most skilled craftsman.

    Post construction, we will continue to work with you to service all equipment and ensure your data center operates at its most efficient with the highest network availability.

    Many administrators and IT Managers are still asking this question. The reality here is that this is always going to be a bit of a challenge when the decision has to be made. The modern business continues to ask more from their IT department, while still spending lessOstec offers both build and outsourcing options!

    Build – To Build or remediate your existing in-house data center, relying on the expertise and resources of your internal IT staff to ensure the availability and security of your system. What kind of advantages are associated with building your own data center?  Mainly control; complete control over an operating environment, including access, temperature, etc. Low risk of losing your lease and the ability to leverage and share existing space.


    Many administrators and IT Managers are still asking this question. The reality here is that this is always going to be a bit of a challenge when the decision has to be made. The modern business continues to ask more from their IT department, while still spending lessOstec offers both build and outsourcing options!

    Even if IT is your core business, setting up your own data center or computer room is an expensive proposition both in terms of money, time and deployment of human resources. Apart from the high capital costs, there are the high day-to-day management costs. Routinely adding new services or upgrading to the latest technology is also not feasible. In this scenario, it makes sense to outsource this service to a co-location, carrier-neutral data center.

    Co-location means that you rent specific space to house your servers along with the servers of other companies in a common physical location. Each company’s equipment is physically secured inside a lockable wire cage or a cabinet. Co-location offers you the flexibility to upscale (or even downscale) your technology and requirements as your business grows (or slows down), without having to make repeated capital investments.

    With Ostec, you also benefit from the services and expertise of an in-house group of technicians – whose central focus is the security, availability and maintenance of your applications and mission critical data.

Taking Full Advantage of Technology Driven Opportunities

A major advantage of technology consulting is that, a business can pursue technology driven opportunities and not get left behind. It helps businesses discover the best use of information technology and also implement, deploy and administer efficient IT systems. A business’s success is determined by its ability to reach out to wider markets and improve customer access.

Maximizing value of IT investments

Business success is assured if users can make optimum use of technology, which promotes business growth and ensures that the IT assets offer high ROI. Getting the best of out of IT investments is dependent on having the requisite IT capabilities and infrastructure that meets the changing demands of the marketplace.

Gain time to focus on core business functions

People are generally happiest doing what they do best. And they get frustrated by distracting tasks that have nothing to do with their essential job functions. The time and effort spent on figuring out Information Technology has a very real opportunity cost. More often than not, researching solutions, implementing new technology and fixing technology problems are extremely inefficient for non IT professionals. IT consulting frees internal staff to spend time focusing on revenue-generating opportunities for the business.
