Future of Dedicated Hosting Delivery

For all the hype, over the last few years an increasing number of businesses have started moving not just distribution but more important business processes online in earnest. The main reason this much anticipated migration has dragged its heels is that change takes time, and businesses going online are faced with hurdles of cost, complexity, resourcing, and marketing at every step of the process.

The workhorse in terms of infrastructure of this fundamental change is hosting.

As many businesses now know, hosting has a wide range of options in terms of cost and function, but it's the growth of Dedicated Hosting that has continued to gather momentum over recent years. The most interesting aspect of this growth is that indicators show that most businesses are at the bottom of the adoption curve and that the most aggressive growth is yet to come.

What customers want

What customers have wanted, but more importantly needed, over the past years has changed considerably. As businesses become leaner and headcounts shrink, so priorities and their drivers have changed. So-called "Have-to-haves" or essential requirements are the issues ones getting any traction, relegating "Nice-to-haves" to the back-burner until they either become irrelevant or are escalated for other reasons.

This phenomenon has seen companies spend less time, resources and money on their online presence than they might have.

Priorities have changed.

Issues that have re-prioritised the importance and investment in online presence and tools now include better brand awareness through greater exposure, increased distribution driving higher sales and new markets, and better processes to increase efficiency and reduce costs.

As customers realise that their commitment to their online tools needs to increase, so too does their requirement for effective development. Once the development has been defined and is nearing completion, the tool requires a means of delivery, being effective hosting. Hosting is then divided into two categories: Shared hosting (otherwise known as virtual hosting, as opposed to virtualised hosting) and dedicated hosting.

Dedicated hosting is a requirement once the environment that the developer requires becomes either more complex. or more customised than a vanilla shared hosting environment. In short, custom development requires the freedom that only a dedicated hosting environment can deliver.
How service providers are meeting customers’ needs

Dedicated hosting has traditionally been delivered by Carriers, Internet Service Providers or Hosting Providers. Of these, it has quickly become apparent that hosting, particularly dedicated hosting, is a specialisation requiring specific skills to deliver the required product offerings.

As dedicated hosting growth gathers momentum, so too does the need for fast, cost effective delivery. Until recently, delivering dedicated hosting has meant a long-winded and complex process for both service provider and customer alike, involving specifying and sourcing the right hardware, burn testing, server OS configuration, application configuration, IDC installation and connectivity configuration and finally a handover to the customer to, only then, start the process of final configuration for production rollout.

The process is long-winded, expensive and complex for all parties concerned. Issues continue for dedicated hosting servers set up this way as, when the times to upgrade disk, RAM or even the whole server, the process begins again from the start.

Virtualisation: Not as good as, better.

New virtualization technology is now set to deliver dedicated hosting in a way that not only eliminates most of the complexity for both service provider and customer alike, but introduces many additional virtualised hosting benefits that have not previously existed.

For service providers, it allows scalable, profitable and fast delivery of premium dedicated hosting.

For customers, it eliminates hardware, hardware drivers and hardware upgrades. In addition, due to the features included in some server virtualisation technology, it delivers far higher levels of availability and allows clones of production environments to be created for seamless development and rollout.

Virtualisation and virtualisation

As either a service provider or a customer, it’s important to understand that many different flavours of server virtualisation exist, bringing different price points, levels of resource control and base-OS independence. Apart from resource control and allocation, stability of, and independence from, the underlying OS is essential to realising all the available benefits of server virtualisation technology and quality virtualised hosting.

Of all the current crop of server virtualisation technology, VMware Virtual Infrastructure 3 seems to lead the market against all of the above criteria, combining the highest available resource control with elimination of hardware drivers. Infrastructure 3 also allows intelligent high-availability redistribution of VMs from failed physical servers to the remaining healthy servers in the farm.

Server virtualisation technology is set to expand its market share as it has in the wider server market – it just depends on whether virtualised hosting service providers and customers alike realise the possibilities available for premium virtualised hosting.

What is Double Password?

Strong passwords should have a significant length and cannot contain normal words. Only random digits and letters of different case. Such passwords are extremely hard to remember and it takes time to enter. But, even strong passwords have their weaknesses. When you type a password, it can be intercepted by a spy program that logs all your keystrokes. Others can see what you type (even if the password field on the screen is masked, the password can be read by buttons you hit on your keyboard.)

Until now, the only solution was to buy a secure token. A secure token is a hardware key that is used instead of or in addition to your normal password authentication. There are two main problems with the hardware solution, though. First, it is expensive. And second, you can use them only with software that has built-in support for this method of authentication.


But, from now on, you can turn any USB flash drive into a secure token! No need to purchase an additional expensive device. All you need is about 2 megabytes of free space on your flash drive or other USB gadget, such as an MP3 player, PDA or even a USB-pluggable mobile handset.

Strong Password



How does it work? Our software, Double Password, installs onto your flash drive. When you type a password, the program intercepts it and converts it into a super-strong password string on-the-fly. You can use simple, easy-to-remember passwords without the risk of being cracked.

Another benefit of using Double Password is that nobody can steal your passwords. Spy programs are useless. Even if someone gets the "weak" password that you type on the keyboard, it means nothing. This password will only work when your USB flash is inserted.

While typical hardware locks will work only with software that supports secure tokens, Double Password works with any software. It simply substitutes your weak password with a strong one.

Double Password can be effectively used to securely lock your Windows account, to protect your laptop and to bring a new level of security to all software that uses password authentication.

optimize broadband and dsl connections

These settings allow you to boost the speed of your broadband Internet connection when using a Cable Modem or DSL Router with Windows 2000 and Windows XP.

Open your registry and find the key below.

Create the following DWORD values, as most of these values will not already exist you will need to create them by clicking on 'Edit -> New -> DWORD Value' and then set the value as shown below.

DefaultTTL = "80" hex (or 128 decimal)
Specifies the default time to live (TTL) for TCP/IP packets. The default is 32.

EnablePMTUBHDetect = "0"
Specifies whether the stack will attempt to detect Maximum Transmission Unit (MTU) routers that do not send back ICMP fragmentation-needed messages. The default is 0.

EnablePMTUDiscovery = "1"
Specifies whether the TCP/IP stack will attempt to perform path MTU discovery as specified in RFC 1191. The default is 1.

GlobalMaxTcpWindowSize = "7FFF" hex (or 32767 decimal)
Specifies the system maximum receive window size advertised by the TCP/IP stack.

TcpMaxDupAcks = "2"
Determines the number of duplicate ACKs that must be received for the same sequence number of sent data before "fast retransmit" is triggered.

SackOpts = "1"
Enables support for selective acknowledgements as documented by Request for Comment (RFC) 2018. Default is 0.

Tcp1323Opts = "1"
Controls RFC 1323 time stamps and window scaling options. Possible values are: "0" = disable RFC 1323 options, "1" = window scale enabled only, "2" = time stamps enabled only and "3" = both options enabled.

TcpWindowSize = "7FFF" hex (or 32767 decimal)
Specifies the receive window size advertised by the TCP/IP stack. If you have a latent network you can try increasing the value to 93440, 186880, or 372300.

Exit your registry and restart Windows for the changes to take effect.

If you don’t want to edit the registry, here's a little TCP utility that is ideal...

Recover data from a quick-erased CDRW/DVDRW disc

Procedure used to recover data from a quick-erased CD/DVD-RW disc

1. Make a file of exactly the size of the cd/dvdrw disc's capacity .
(this step may not be needed)

2. With Nero I created a new project and added the file to it so that I have the disc filled. I gues you can also fill up the disc with other files.
The reason why I fill the disc is because I want Nero to make a session that uses the entire disc. Like I wrote earlier in this thread I experienced that my CD/DVD-Drive refuses to read off the disc beyond the session's boundaries. When you quick-erase a disc there is no session anymore so the drive will not read at all. Burning a new session will overwrite the data and burning only a small session will NOT make the drive read the other data that is still on the disc.
The reason why I used the one big file is so that I could later on recognize which part of the disc was overwritten by this file because this file contained all zeros (0x00).

3. I pressed burn and selected disc-at-once. Then while Nero was burning the leadin I pressed cancel. My CD/DVD-Drive finished writing the lead-in and Nero reported an error.
This is what was accomplished however: Now the disc contains a session that says that the used disc size is the complete disc. Nero did not get to writing file because I cancelled it. Good thing because I don't want Nero to write any files because my old data will get overwritten!
I gues it works the same with different writing software. Another method that I used during a test was simply press the reset button of the computer when the burning software was done with writing the lead-in and started with the files.

4. I had to restart the computer after cancelling burning.
With the cdrw disc inserted I saw in "my computer" that windows recognized that the disc was 650MB, clicking on it gave an error. Good so far!

Now with IsoBuster you can extract the sectors from a disc to a file. This is what I did.
I gues that if you have data-recovery software at this point it will be usefull because now (if all went well;)) the CD/DVD-Drive WILL read data from the entire disc. Anyway, I used ISO-Buster because the files that I needed to recover where a bit odd for nowadays (.XM, .S3M, .MP3):
In IsoBuster I had to do several steps:

Step 1: Find out from and to which sector the drive will read
By choosing "Sector View" you can look at any given sector.
Here I found out what the first and the last sectors where that are readable. (Hint I used the method for the old game: "Gues a number below 100, I'll tell if it is higher or lower than what you gues")
Step 2: Extract the actual sectors
By choosing "Extract From-To" you can extract any given range of sectors to a file. My disc was a data-disc so I choose the first extraction type "User data, 2048 bytes/block...".

In the end I got a .tao file which was about 650MB. I ran several programs on it to look for files inside a file by searching for file-header-paterns:
1. Multi Ripper 2.80 (for DOS, for the .XM files. It does many other file formats as well (jpg,png, bmp,wav,etc,etc +100). Try google with this query: Multi Ripper 2.80. I still had the file from good old days but I saw several good search results)

2. Winamp for mp3.
Winamp will scan any file when you give it the extension .mp3 and play it as one big song (so I renamed the .tao file to .mp3). I used the discwriter to get a .wav and the Adobe Audition to manually cut and save my songs. I looked at the MP3 file format and it is hard to find an mp3 file in a big file because it has no clear header just a bunch of mpeg-frames in most cases for me . A lot of my files had no ID3v2 or ID3v1 tags... But after a couple of hours I recovered everything.

Finally a list of used stuff:

Software:
- IsoBuster v1.9 and above
- Nero 6.8 and above
- Multi Ripper 2.80 and above
- WinAmp v5.02 and above
- Windows XP Pro NL (patched up)
