What’s that, you say? This week’s topic may seem a little ‘surreal’, but there is, in fact, such a thing as a zombie server and there’s increasing numbers of them out there draining away power and resources that could otherwise be put to more productive purposes. It’s certainly a power efficiency problem, but it’s also an environmental problem as well as a capital resource problem. Zombie servers have now become a major hassle for data centres around the world. Comatose devices running with no external communications or visibility, and contributing nothing in the way of computer resources. Here at 4GoodHosting, we like to think that staying on top of major trends in the industry is a big part of what makes us a good Canadian web hosting provider. And considering that estimates now suggest that there are over 10 million zombie servers worldwide, this is definitely one that we’d prefer to never be discussing again. These 10 million+ servers are wasting the equivalent of the electrical power generated by eight major power plants. Reliable research indicates that 30% of servers are comatose, and that means that almost one-third of capital in enterprise data centres is squandered. Then you add the security risk posed by zombie servers because of how they aren’t patched or maintained. The Horde is Growing It’s a fact that identifying a zombie server isn’t easy, and particularly for those who don’t interact with them frequently or extensively. More and more data centres with hundreds and thousands of comatose servers are completely unaware of the power these devices eat up. Many of these ‘zombies’ remain anonymous, devouring energy while providing no real active function. Example of their evil ways include dozing off for months at time, generating heat for no real reason, and accelerating the power meter simply for the sake of doing so. And more often than not the only way to identify them is to walk up down the aisles of a data centre with a clipboard taking notes of the transgressors. That’s something few operations managers have the time to do. Consider as well that another massively problematic issue related to these zombie servers is...
