Network Infrastructure Components

The following are common components of network infrastructures, implementing them correctly can drastically increase network speed and network security.

  • Routers and switches
  • Firewalls – more about firewalls and security here.
  • Storage Area Network (SAN)
  • DNS

Routers and Switches

Routers connect networks of your infrastructure, enabling systems to communicate. You need to ensure that the routers have spare capacity after the deployment to cope with projected growth and usage.

In a similar vein, switches connect systems within a network. Routers or switches running at capacity tend to induce escalating bottlenecks, which result in significantly longer times for clients to submit messages to servers on different networks. In such cases, the lack of foresight or expenditure to upgrade the router or switch could have a personnel productivity impact far greater than the cost.

Firewall Access Control

Firewalls sit between a router and application servers to provide access control. Firewalls were originally used to protect a trusted network (yours) from the untrusted network (the Internet). These days, it is becoming more common to protect application servers on their own (trusted, isolated) network from the untrusted networks (your network and the Internet).

Storage Area Networks (SANs)

Fujitsu Eternus - Understanding the data requirements of the storage system is necessary for a successful deployment. Increasingly, SANs are being deployed so that the storage is independent of the servers used in conjunction with it. Deploying SANs can represent a decrease in the time to recover from a non-functional server as the machine can be replaced without having to relocate the storage drives.

Domain Name System (DNS)

Servers which make heavy usage of DNS queries should be equipped with a local caching DNS server to reduce lookup latency as well as network traffic. We are experienced at setting up these solutions for our clients to provide the best speeds without compromising security. System Integration.
We can build custom solutions combining hardware, software and cloud services. This enables us to offer each client a bespoke solution using industry standard hardware and software components. Making these system work together well is what we do best! Systems Integration diagram.
