Network stability is tightly connected with “high availability” and redundancy in links and device links. Single point of failure and misconfigured networks appliances can cause network downtime as well as network instability.

Network Security appliances like Firewalls and Intrusion prevention appliances are very important to protect networks from disruption, and unless these appliances are configured properly and network security policies and procedures are regularly maintained and implemented, your network could be still vulnerable.

Different types of network attacks have been implemented and developed throughout the years with different methods to prevent and hide from security appliances. Such threats include viruses, browser and application based exploits, DDOS etc. Usually these threats are either planted to gain remote or local access to specific information and data, or to stop a certain network service from working. Up to date network security procedures can prevent most of these attacks.

-By installing network security appliances to separate and scan all incoming and outgoing information to and from the organization.
-By keeping all software and operating systems patched and up to date at all times.

-By implementing a tight security policy throughout the network and performing regular checkups.

Most common attacks come from inside the network itself, usually enterprises and companies implement all kind of security measures on the edge of the network and leave the inside of the network wide open and vulnerable to attacks. Protecting the network from within is as important as protecting it from outside. And so, security appliances are added to separate and inspect network traffic to and from datacenter to ensure maximum protection.

VPN networks are very common nowadays, and almost every company has a VPN network to connect their branches across public networks such as the internet. Some of the protocols used for VPN traffic encryption are outdated and have been cracked and proven to be unsecure. In order to maximize the data confidentiality and security, companies should migrate to more recent security protocols and algorithms.

WAN optimization appliances have been proven to increase data transfer efficiency across WAN links while delivering business critical applications over WAN or VPN. These appliancies help eliminate the need for fast and pricy WAN links needed to reach a satisfying network application performance level.

The question should be: "Why haven’t you moved to the cloud already?"

Not having to worry about server maintenance is more than you could ask for! And the cloud gives you just that and more:

-Work from anywhere, anytime and on any device.

-Never worry about losing data because Disaster Recovery is implemented on all servers, giving you constant automatic back-up.

-Gain free and automatic backup for your servers for years and years to come! You also won’t need to buy the new version of the software every 2 – 3 years.

-Reduce CAPEX and maintain OPEX. By moving to the cloud you will say goodbye to all your IT problems!

By illuminating all common IT problems, your employees and customers can focus on more important matters at your company or organization.

CRAC stands for Computer Room Air Conditioner, which is a machine used to measure, preserve and control the temperature and the distribution of airflow in datacentres using perforated air tails.The process is carried out by having cool air stream through the racks where the air gathers heat and flows out of the rack.Split air conditioning, on the other hand, cannot manage the air distribution, or humidity like CRAC.

Cold aisle management provides enhanced and improved airflow, higher density installation, improved heat exchange via air handler capacity, and central plant energy efficiency by giving and obtaining elevated water temperatures. It also has the ability to isolate hot aisle and cool aisle. These benefits allow you to save costs while enjoy well-managed air flow in your data centre.
