Now that’s what I call… Tech Predictions 2017

predictions

At this time of year, it is customary to look back at the past 12 months and make some random or not-so-random guesses as to what will happen over the coming 12. As such, what could be more fitting for my final post of 2016?!

Here’s a few of my personal best, worst, and easy guess candidates for 2017…

Tekhead Predictable Tech Predictions 2017

Easy Guesses

Come on Alex, even Penfold could have predicted these!

  • AWS will continue to dominate the cloud market, though the rate at which they deploy new features will start to slow (over 1000 a year is pretty unsustainable!). Their revenues will continue to grow at gangbuster rates, however their market share will be slightly eroded as people experiment more with their competitors too.
  • Microsoft Azure will grow massively (not quite 100% but not far off it). Their main growth will probably be in hosting enterprises and typical line of business applications as people move their legacy junk into the cloud. The recent announcements of the Single Instance VM SLA of 99.9% will definitely accelerate this as customers will feel less include to refactor their applications for cloud.
  • Distributed everything!
  • Docker will start to become more mainstream production and less Dev/Test.
  • Google will kill off at least one popular service with multiple millions of users.
  • The homelab market will reduce as people do more and more of their studying in the cloud.
  • Podcasting will become the new blogging (if it hasn’t already!)
  • DellEMC will continue to hack off bits of its anatomy to pay back that cheeky little $67Bn debt.
  • I continue to use memes as a crutch to make my otherwise lifeless articles marginally more interesting!obvious
Best Guesses

Its on the cards… maybe?

  • Google will continue to be ignored by most enterprises for Cloud IaaS. They will gain some reasonable growth in the web application space after another mass marketing activity to developers, ISVs and hosters.
  • Oracle grows Cloud revenues 50% or more but market share remains small. Their growth is mainly driven by IaaS revenue as customers begin to move their workloads to be closer to their data in the Oracle PaaS and SaaS services.
  • There will be no major storage company IPO in 2017, i.e. over $200m.
  • Many storage startups will run out of funding and die on the vine (depressing I know!). Their IP will be snapped up by the old guard storage companies in the proceeding fire sales…
    fire-sale
  • 3D XPoint will begin to creep into storage arrays by the end of the year, fuelling another storage VC funding bubble for at least another 12 months for any company who claims to have an innovative way to use it.
  • A major cloud provider suffers a global outage.
Worst Guesses

These probably won’t happen, but if any of them do, I’ll claim smugly that I knew they were always going to!

  • Pure Storage will make an acquisition of a storage startup to create their third product line, perhaps a secondary storage company (i.e. not just all flash) along the lines of Cohesity.
  • Cisco will buy a storage company. They will be more successful at integrating it than they were with Whiptail! (Which wouldn’t be difficult… 😮 )
  • Spanning a single application over multiple clouds becomes a real possibility, as one or more startups come out of stealth to provide innovative ways to span clouds. Nobody buys into it, except maybe for DR.
  • Tekhead.it becomes the most read blog in the world in 2017
  • Cats take over the planet and dogs are forced to form a rebel alliance which is ultimately victorious when a chihuahua takes out the entire cat leadership in one go, with a stolen reaper drone.Cats vs Dogs
  • Jonah Hill wins Strictly Come Dancing, narrowly defeating Frankie Boyle and Charlie Brooker in the final.
And finally…

Here’s wishing you all an awesome, fun and prosperous 2017!

Data Corruption – The Silent Killer (aka Cosmic Rays are baaaad mmmkay?)

Minion Assassin

If you have worked in the IT industry for a reasonable amount of time, you have probably heard the term bit rot, referring to the gradual decay of storage media over time, or simply Data Corruption. What I never realised was what one of the primary causes is behind bit rot, and the amount of effort the storage industry goes to prevent it!

At Storage Field Day 9 we attended one of the most genuinely fascinating and enjoyable sessions I have ever seen. It was “proper science”!

Apparently one of the dominant causes of data corruption in SSDs, is in fact something which completely blew my mind when I heard it! Believe it or not, bit rot and data corruption is often caused by cosmic rays!

Cosmic Rays cause Data Corruption!

These cosmic rays are actually protons and other heavy ions which originate from the Sun, or even distant stars! Next thing you know these evil buggers are coming down here, taking our bits and stealing our women! Ok, maybe not the last part, but they’re certainly interacting with other elements in our atmosphere and generating storms of neutrons (we walking flesh bags actually get hit by about 10 of them every second but as we’re not made primarily of silicon, no biggie on the data corruption front!).

These neutrons occasionally also then slam into integrated circuits, and more occasionally still, this causes a bit to flip from a 0 to a 1, or vice versa.

data corruption mind blown.jpgNow a flip of a single bit might not seem like a lot, especially with CRC and other features in modern HDDs, but the cumulative effect or a large number of these flips can lead to corrupt data. Furthermore, corruption of even a single bit of certain data types, such as the vast quantities of DNA data we plan to store in the future, could mean the difference between you being diagnosed with cancer or not!

As such, Intel have introduced a feature within their SSDs which will deliberately brick the drives if they detect too many bit flips / errors! More amusingly, they adopt “aggressive bricking“, i.e. brick the drives even when minimal data corruption is detected! A brilliantly ironic description for something which is actually trying to protect data, as this has the effect of causing your RAID or Erasure coding data protection to rebuild the drive contents on another drive, therefore ensuring that you don’t end up with corrupt data replicating etc.

Intel actually test this using a particle accelerator at Los Alamos Neutron Science Centre, by firing neutron beams at their drives and checking the data corruption rates! But don’t worry about the poor drives… it’s all over in a flash! 😉

This is genuinely an absolutely fascinating video and well worth spending 45 minutes watching it:

Also for those of you who may notice some snickering and shaking of shoulders going on in the video, it was partly down to the crazy awesomeness of the subject, but also due to some very humorous twitter conversations going on at the same time! I finally understand the meaning of the term corpsing now, having most definitely experienced it during this session! Vinod did an awesome job of putting up with us! 🙂
