Reduce power and space requirement in data centres

Fast application and service provisioning

Improved manageability

Business continuity

When these factors are measured by a survey taken by f5 few years a go we got the following results. This clearly explains that the Businesses are focused to do server consolidation and reduction of power and space requirement which is the driving factors even today. The types of virtualization do we currently have ? as discussed this on my previous post, I am going to compare them today. According to surveys taken recently we have the following stats. This clearly explains us that most of the Virtualization technologies are been used today, however still the most popular one is Server virtualization. Never the less this is taken on a different level today to get the Desktop virtualization for the end users companies like Citrix and VMware have got a lot of powerful products for this.

Finally I would like to discuss the products which are used in the industry and to what extent. The most widely used product is VMware ESX and then comes Microsoft Hyper-V. As we can see from the table below.

I will be disscussing VMware and Hyper-V Technologies and theire benifites over one and outher in detail in my next post.

Eventually someone else started using their network; they only realized this after they felt that their connection became slow. This could have been worst as people can capture all the packets and get the critical information like online banking information, CC numbers etc. The truth is even if your using secure Wi-Fi connection, wireless technology can still be very easy to compromised, how ? Check out for yourself Googleit – how to crack Wi-Fi network and you will get the answer. However we can avoid this just by making sure we do not use simple name or dictionary words as a passphrase. Always use complex passphrase /WEP/WPA2 keys and make sure you have a key which is at least 10 to 12 characters long. Now let’s get to the point How to secure Your wireless network ? Change Your network name and Your router login information Simple job just login to the router using the details from Manufacture. Usually found at the back on the router long and change the Name of the network and login information or at least the password. Secure Your Wi-Fi network: If you do not secure your network it will be open for anyone who can get your wireless signal. WEP (Wire Enabled Protection) this should only be used if you have old laptop that does not support the advanced encryption. If you are using this make sure you use 128 bit encryption. WPA 2 encryption is the best so far, However I suggest you keep a long passphrase and complex at the same time. Hide Your network name (SSID) Although most people don’t do this, but I strongly suggest you to hide the SSID. Simple logic if they can’t find your Wi-Fi signal you will be less vulnerable to get hacked. Enable Software and Hardware Firewall: Let me explain Software firewall is the firewall built into the Operating System i.e., Windows Vista or Windows 7 just enable it. Hardware firewall ah might be new to some of us, but most of the routers built today even the cheapest one has a firewall program built into them. So all you got to do is login to the router using your admin login and enable it. Hope you find this post useful feel free to comment if you ever used open / un-secure Wi=Fi.]]>
