As any technology that is new more commonplace, to the point of commoditization, price starts to become one of the main points of differentiation. You’ve only got to look at the way mobile phones are sold to see that in action on a basis that is daily.
It’s also present where cloud hosting is concerned. No one would argue that price isn’t important; it is, rightly, a vital commercial consideration of any purchase. But when price is the point that is focal of conversation it can be all too easy to lose sight of the combination of factors that go into determining that price. Particularly when it comes to technology that, because of its utility-like nature, is almost taken for granted.
It’s all too very easy to switch off a little and start to become ambivalent towards the things we are acquainted with, and so it never hurts become reminded not just of what something does, but the way the nuances of its performance, and prices, can affect the rest of our lives that are working.

Tiers tend to be more than just stones that are stepping
That’s definitely the full case when it comes to uk colocation tiers. This standard methodology for defining colocation uk engineering standards, in tiers one-to-four, lends it self too easily to being dismissed as superficially obvious. Most likely, Tier 1 is the least well performing and Tier 4 is the best, Tier 1 the cheapest option and Tier 4 the most expensive right? As soon as you’ve got your mind around that, what else will there be?
Therein lies part of the nagging problem with taxonomies; simple to read labels can conceal an abundance of valuable information.
Getting your face around some of the differences in the tiers will mean you’re able to make better decisions when it comes to choosing a cheap colocation, and most importantly you’ll avoid a true number of potential pitfalls.
Crunching the figures
First let’s consider the differences that are uptime the four tiers.
Tier 1 equates to the fundamental requirements for a uk server colocation – an individual distribution path for power and cooling serving the processing hardware, and non-redundant capacity. Annually, uptime would be at the rate of 99.671% and include 1,730.4 minutes (1.20167 days) of downtime.
Tier 2 infrastructure provides capacity that is redundant can be swapped in and out without causing system failure. It will also include one non-redundant distribution path. Tier 2 data centers aren’t intended to be fault tolerant when it comes to things like natural disasters, nonetheless they have 99.741% uptime, and 1,362.2 minutes of downtime, per year. That means almost 23 hours.
Tier 3 Rackspace colocation have actually one active and one passive distribution path. They’re built to be more resilient, although they’re not intended to be completely immune to disasters. But they will better withstand them, because of higher capability equipment. Tier 3 1u colocation pricing offer 99.982percent of uptime and 94.7 minutes of downtime each year.
Tier 4 are fault tolerant with two active distribution paths, offering the level that is highest of capacity, including mission-critical levels of tolerance, fully redundant subsystems and components with concurrent maintainability. They also have dual-powered cooling systems. Uptime is 99.995% per year, and the annual downtime is 26.3 mins.
Get the stability right for your online business
Unless you are running genuinely mission-critical applications and downtime is utterly unconscionable, you are unlikely to want to shoulder the not insignificant investment a Tier 4 data center will require, which could be as much as double the cost of a Tier 3. Tier 4 also involves a very high environmental overhead, and a much higher carbon footprint.
Similarly, unless all you’re doing is running a simple information-only, non-transactional site, you should walk far from Tier 1 too.
Identifying which for the two remaining tiers is right for you comes down to understanding the impact of a number of the differences.
Even at the headline degree, the difference in yearly downtime between Tier 2 and Tier 3 is substantial, from almost one full day, to just over an hour and a half, respectively. Are there going to be cost implications? Of course there are. But pause, it takes to fly from London to Sydney if you will, and reflect on the difference in those downtime numbers; one is the time. The other is the duration of a football match, with a little stoppage time added on.
That’s a considerable difference, and you’d need to imagine carefully about the potential for exposing your online business to harmful consequences because of this of it. A lot can happen in 24 hours.
You need to map that against what’s being offered by your data center if you have SLAs in place with your clients and customers that include penalties and reparations for missed application availability. If unexpected outages prompt modest reparations that are financial important computer data center, for instance, how does that stack up with the potential losings for the company caused by those outages? Will it make a difference if customers come to your site and can’t transact with you? Will your clients invoke penalty clauses in SLAs if applications they rely upon are impacted?
Making the right choice
Weighing up which data center tier are the fit that is best for your business operations is more than a simple price vs uptime equation. Price differentials are inexorably lined to tiers, but you can’t do a comparison that is like-for-like these scenarios unless you are fully up-to-speed with most of the implications. You will need to peel back some layers and determine what the implications are in the occasion the lights stop.
A cure for the best, plan the worst? Possibly. But be familiar with the have to do a little risk evaluation when it involves deciding where your organization shall be hosted. Knowing which data center tiers your potential providers operate from will always be an essential first step.
