What is our Colocation Power Usage Policy?

Power is one of the largest expenses in running a datacenter, and of course datacenter can easily make loss or close shop if improper manage of their power policy. Today, you can notice that almost every hosting provider in Malaysia are now implementing such  policy in controlling power usage for their colocation solutions (mainly also because datacenter in Malaysia have started to bill for additional power and limit the power allocation. Last time some just give no limit!).  

In fact, Power has become one of the key points in datacentre colocation, even more so than space. For colocation market, Power Usage Policy (PUP) is only applicable to Multiple Colocation solution, as Single Colocation solution is only giving one power point for one server. For colocation market, Power Usage Policy (PUP) is only applicable to Multiple Colocation solution, as Single Colocation solution is only giving one power point for one server. 

If you have gone through some web hosting provider for Multiple Colocation, and I guess you may seem some specification terms like 'Power Allocation' with 0.4kW for 10U Colocation or 0.7kW for 21U (Half Rack), or 0.7kW for 42U (Full Rack). Meaning to say, you are giving this such of power for your colocation every month, and you will be charge 'extra' if exceeded the limit. Currently, the market rate for power is between RM0.68 to RM0.75 per kWh (where this is very much depend on the datacenter building & infrastructure companies such as AIMS). From our survey, most of the colocation providers are putting this cost back-to-back to their clients). 

But honestly, how many of you really know how to count if exceeded the quota? Let me use one scenario to explain on this.   

"Our default power allocation for Full Rack colocation is 1.5kW (which is a standard practice in market). Assumethat you are estimating about 3kW monthly to support all your servers, then you need additional 1.5kW power with additional of RM0.68/kWh. So how much is 1.5kW? 

1.5kWx 24 hours x 30 days x RM 0.68/kWH = RM 734.40

In summary, we are concluded the power usage formula like this: 

<Total Usage in kW> x 24 hours x 30 days x <Cost of Power>

Like I mentioned earlier, most of the colocation providers will apply the same power cost that vendor charged them back to their colocation clients, so you can roughly know their cost to their vendor on power, as well as to predict their margin in market. 

Power Usage Policy (PUP) for Shared Rack Colocation: 

As we know, Power Usage Policy is only applied to Multiple Colocation solutions such as 10U (Quarter Rack), 21U (Half Rack), 42U (Full Rack) and etc. Most of the server racks in EVERWORKS are only installed with one power meter to measure its power usage for each different rack, as well as to configure with 1.5kW as our default power usage allocation. That's mean we will be allocating 0.04kW (1.5kW /  37U) for each colocation 'U'. As we know, one full rack has 42U of colocation space, then why we divide by 37U in this formula? This is because every shared rack that designed for Multiple Colocation will take up 4U space to install the tray. Hence, we can't bundle this 4U space into our client's bill.

Implementation of our Shared Power Usage Policy is just like how we managing our Shared Hosting servers, all available resources within the server and network will be shared among all existing web hosting clients. For this Shared Power Usage Policy, we are equally sharing the default of power allocation of 1.5kW. E.g. if you are subscribed to 10U Multiple Colocation, then you will get 0.40kW (10 x 0.04kW = 0.0394kW) of power allocation.

Your next question will be, how do we 'share' the additional charges if the rack has exceed the limit of 1.5kW? Just simple, we will share the exceeded power usage among the existing colocation clients under the rack with according to their occupancy space. E.g. assume that a rack has hit 2.0kW end of the month, that mean the total exceeded power usage is only 0.5kW (2.0kW - 1.5kW), or 0.013kw per U. If you are subscribed to 10U Multiple Colocation, then you will be responsible for 0.13kW, which is equal to RM63.70  (0.13kW x RM490).

What is EVERWORKS's Hybrid Bandwidth System?

EVERWORKS is among the 1st Datacenter Hosting Provider (DHP) in Malaysia, who deployed the Hybrid Bandwidth System that allow our customers to customize their bandwidth pattern – either to focus on local or international bandwidth. Today, a lot of web hosting companies and datacenter providers already configured such bandwidth system as their main bandwidth system that packaged to all their products, and of course it can make your package look more price competencies than who are still bundling with oversea upstream providers. 


EVERWORKS’s Hybrid Network is designed for our datacenter hosting clients who need to serve more Malaysian traffic than international visitors. Hence, a lot of our customer who are colocating or renting servers under this network system are usually serving more Malaysian than oversea traffic for their online business (meaning to say most of their internet traffic is from Malaysia). 

Colocating your equipment with EVERWORKS’s Hybrid Network gives you more than just state-of-the art datacenter facilities, but to saves your total recurrence investment on bandwidth in today’s economy. You may visit our website, www.everworks.com for more information on our server colocation package, and we have categorized our package very well with this Hybrid bandwidth. Furthermore, we still offer the non-hybrid bandwidth system to some of oversea clients, who are only or mainly serving oversea traffic (which is currently available in our AIMS Datacenter, package name as Premium). Below are the some explanation when evaluating EVERWORKS's colocation package.  

Example of Who Should Consider our Hybrid Bandwidth System? 
1. Telcos Solution Provider 
2. Malaysian Forum Provider 
3. Malaysian Blogger 
4. Malaysian Portal 
5. Local Data Backup (SAN) 
6. WAP-based Solution Provider
7. Local Messaging Providers
8. Internal Billing & CRM System
9.  Disaster Recovery Site


Finally, let's talk about how Hybrid Bandwidth is born in Malaysia's Internet Industry? Firstly, I think everyone of us should say thank to the MYIX (Malaysia Internet Exchange) - www.myix.my, who formed in 2006 after the reviewed of MCMC, with main objective of moving back local traffic being routed via MyIX away from international bandwidth links. Another simply word, without this implementation, Malaysian Internet users and providers will keep paying the higher price for their bandwidth. And this is definitely stopping the industry to grow! To know more about them, you may visit their website at www.myix.my. 

So what is the benefits? Of course, by escaping this, many of local operators especially the smaller ISPs enjoy cost savings due to domestic peering. Technically, by peering within MyIX network, mean the local traffic (such as a TM users accessing to Lelong.com.my servers hosted in TM or any local datacenter in Malaysis) is kept domestically, therefore, the boomerang traffic is kept at a minimum and latency between peering operators has improved. In another word, why we are paying so much higher bandwidth before this, is due to all local access are passing by all these international upstream provider such as Level3, Pacnet, PCCW, and etc.

Are you vulnerable to SQL Injection?

Recently, we have came across some enquiries with regards to 'SQL Injection Attacks', as well as to 'How to Protect your Database in some simply' to prevent such attacks! Basically, what is SQL Injection? To understand how this thing works, and it will help you tore-evaluate your online business well! SQL Injection Attacks can be a very serious threat to your online business. Today, we are trying to share you guys some basic information on 'How a SQL Injection Attack works?', and "What you can do to prevent it'? 


How a SQL Injection Attack works?
Any site that runs on a database has the potential to be compromised by this threat. When a malicious person or script is targeting your website, they try entering certain special characters and strings in any area of the site that accepts user input. These areas are usually Forms for user data such as a login form or comment posts. When the form is submitted, your site sends the data that is in the text fields to the Database Server in what is called a "Query".

What you can do to prevent it?
The object of SQL injection attacks is basically to modify the query so that it runs malicious code. This malicious code varies between attacks, but if successful, it can gain access to all the data in your database, including modifying content. To secure your site from these attacks, you will have to inspect your coding. Your primary defense is to tell your developer to ensure that your site is safe from SQL Injection Attacks. Most developers will know what this means; any user-inputted data is validated and sanitized to ensure it is not malicious.
