We get the impression that going to the Cloud means signing up and getting the payment and login details. Of course this is false. We have no end of articles telling us about teething problems, or being better off with hybrid or private or public cloud or anything other than what we had before. But there are still more things to consider, and that means wading through a lot of figures and making a few worrying decisions. And actual experience might change a few decisions and opinions too.
The speed will vary according to which cloud server that you use, both the company and the options within that company. Bigger machines can be slower, and the reasons for this vary. This is complicated further by the fact that different test programs can run quickly in some situations but less quickly in others, and not run at all in the case of some servers who aren’t set for that particular software.
It would make sense if the more expensive services were faster, or had some other advantage; but this is not always the case. More CPU’s will be faster, all else being equal, but while 8 CPU’s will be faster than One they are unlikely to be 8 times as fast. Windows Azure machines were more than twice as fast when they used the 8 CPU’s option instead of one, but that doubling of speed came at 8 times the cost.
If you increase the number of CPU’s but keep the same amount of RAM you might save some cost. But this can affect the performance in unpredictable ways. Sometimes a 2 CPU Machine is faster than a single CPU machine with the same RAM, but not by a large amount (perhaps 30%). Sometime the 2 CPU is actually slower.
Google Cloud seems to have a fair way of tallying their performance with price, so that their expensive options do have significantly better performance. How that compares to the options offered by another company is another matter.
To make matters more confusing the performance varies over time even with the same system and provider. If you’re using Cloud you are sharing resources with other users, because that’s what Cloud is about. If a lot of computing power is being used by a lot of other groups, then you don’t get any special consideration; things will be slower. Occasionally this works to your advantage and you get bursts of high speed interaction, but only at off peak usage times. If you only want lots of computing power for short periods of time this might be fine. Constant usage, however, will probably mean fluctuating speeds.
Fluctuating Cloud speed might make a smaller provider more attractive, or a super large provider with greater resources; but you need a lot of CPU’s and RAM to achieve significantly higher speeds. Even then it’s had to know which option is best, as speed still varies with the application, and will fluctuate with user traffic. You can’t know these things till you (or somebody else) has tried the service, and even then it might degrade if they accumulate more clients, or improve when they decide to upgrade.


– Security will always be a concern. But this is most noticeable in a time of transition, specifically a business’s transition to the public cloud. A mixture on new and established approaches will be used and modified/developed for the cloud environment. There will always be hackers and other threats, but the cloud will end up at least as safe as previous computing models.
– Hybrid cloud, the combining of public and private, will be common. Hybrid cloud is not a set template, so each company will have their own combination that integrates the two forms. The solution provider will need the skills to do this, but there should be plenty of work for those who are capable.
– Mobile apps already allow employees to work from anywhere. Having half a dozen enterprise apps or more on your smartphone will soon be quite regular. Offices will become further decentralized as employees work from wherever they are.
– The phone and IT systems may merge; mergers and acquisitions between companies may be common, and hopefully mean well integrated services.
– The internet of things has been imminent for a while. If it seems to progressing slowly it may be because of the huge range of items and services that may come about. And the fact that the changing computer landscape means nothing can be finalizes till standards are set. Watches and Google glasses have been selling for a while. Other wearables such as clothing with sensors also exist. Expect home appliances, furniture, healthcare, manufacturing and so much else to be net connected.
– Many tends followed or predicted the past have proved false, often comically so. We tend to notice either the true patterns or the laughably false ones at any point in time, and draw attention to one or the other. Really, some patterns prove accurate, some do not. The fact that the false predictions are permanently recorded on the net proves embarrassing; the true predictions are also recorded, but just seem obvious in hindsight.
