People generally have a question about good host, very few of the clients are really eager  to know about the Datacenter where the servers are stored. This is also very important.

Lets have a look of the some of the aspects of the Datacenter:

Datacenter spends a lots of amount on the hardware, license, and maintenance, however the most of the cost is spend on the power that it needs.

Power consumption: It needs power consumption to keep the servers running 24×7x365. Hence as the power is consumed non stop heat is generated. There is a need to keep them cool as well. It takes a big amount of power to cool a single server.

How it becomes Inefficient?

Traditionally datacenters are thought to be inefficient environmentally. As compared to older days, power was the lowest cost of the expense, computing was precious, if a little amount of power wasted a large amount of computing was needed. This was in early 70 and 80 where power was never a problem, ample of amount was available. This is not the case in 2009. Power has become more expensive and less is amount. Although this is the case some of the datacenters do not take care of the power consumption. According to the report in 2008, it says that only 6%  of server capacity is bielng used and the data centers facilities to run at no more than about 56% capacity.

Can we cool it in a cheaper way?

The answer is yes.  Some ways can help you in this concern.
Virtualization, resource management and physical server consolidation are three methods which you and your hosting company must follow to save the power consumption and increase the data center efficiency.

Virtualize the servers:

Virtualize comes into picture when you think of getting every bit of power out of each bit of piece of hardware. This can conserve a great amount of energy.  It help you in consolidate your server requirement onto some fewer physical machines. The virtual machines consume only 1/50 amount of the power. E mail servers, web servers and applications will just act as if they are running on individual boxes.
Using Grid Grid and the EPA, make the datacenter more efficient and greener datacenter. The products such as Vmware provides some of the highest consolidation rates on a secure and reliable platform. With this technology the unused severs can be powered off and turned back when needed.
This VM ware’s hardware based virtualization also offers a great application access for users, faster installation of new servers and better uptime. This helps the server to reduce the carbon footprint and save the money for you. It also increases the companies competitiveness.

Resources : DRS and DPM.
Cost can be reduced through virtualization by using two more technologies.
DRS: It is a short hand for Distributed Resource Scheduler. It helps to monitor the clients and company’s utilization and can intelligently assign the resources as needed.
DRS allows to assign the resources on the priority basis, you can ensure that it gives priority to the critical applications first. It provides the dedicated environment to the business units, without keeping the resources idle.
DPM: Distributed Power Management, helps in optimizes the power consumption by continuously monitoring power usage and automatically consolidating workloads and power off the resources that are not needed. When the load of the server is less the DPM shifts the server workload to the optimum number of physical servers and turns off the others. When the load increase the original server is back online.

Consolidating Servers with blades:

Energy footprints can be reduced by using the blades, it allows multiple servers to be consolidated on one chassis. There is one management interface per blade and adds more advanced management features.

Green Datacenter : Power and heat generation problem is been encountered all over the world. Many of the  organizations and projects are working for the cause to address the problems.

By using above techniques you can certainly save some of the power consumption in the organization. When it comes to the heat generation , the heat generated in the datacenters is wasted, there is a research going on the recycle the heat generated in the Datacenter.

Anyone is the world will not want their things to be kept insecure. If we say about the web applications, they are insecure too. If we spent time, money and efforts creating a web application why not a further step in protecting them. In the case of web application if you don’t secure it anybody can copy the work and the code. This issue was highlighted by two PHP developers and they thought of the software called Zend optimizer tool from the Zend Technologies.

This optimizer tool helps you to use the Zend Guard encoded files. If you don’t use this tool the code which is Zend guarded cannot be executed. If this code is encoded the visitor will be to interpret it, but won’t be able to see it. This tool enhances the performance of the PHP applications. The zend optimizer goes through the code generated by the standard Zend run time compiler and then it will optimize the code for the faster execution. Even though the optimizer runs every time the page is executed it has a very little or you can say negligible overhead. It speeds up the code execution process with 40% to 100 %. Additionally it will enable PHP to load  and execute the files that are encoded by using the Zend guard.

Zend Optimizer has a limited functionality to only interpret the encrypted the code. In actual to encrypt tit you need to use the Zend guard. This Zend guard will convert the code in the PHP format to the binary equivalent known as “Zend Intermediate Code“. When the conversion is over the new encoded files will take place of the original regularly coded PHP files. Zend guard is helpful in suggesting if any module or functions needs to be excluded from the encryption process for the better development time.

Lets see some of its specifications.

Supported Operating systems, Platforms.

Linux : Linux x86, Linux x86-64, Linux Power.

Solaris: Solaris Sparc 8, 9, 10, Solaris x86 9, 10.

Free BSD x86 5.x, 6.x

Windows x86 2000, XP, 2003.

OS X Mac Power

AIX pSeries 5.

Web Servers it supports:

Apache 1.3x

Apache 2.0.x (prefork mode)

IIS 5,6

Support for PHP versions:

PHP 4.2.x to 4.4.x

PHP 5.0.x, 5.1.x

Things to be ensured before using the zend optimizer. Zend optimizer will not run if the following PHP settings are enabled:

1. Thread Safety.
2. Enable Versioning

Zend optimizer is free and easy to use software. Mainly good hosting companies use this utility for the security of the web applications and code as explained above
