Trends in data centres
Data centres in 2016 will be characterised by elasticity, density and decreasing latency, says John Schmidt
The data centre, as we have come to know it, has changed. With bandwidth needs driven by trends such as wearable technology and big data, we see a shift in how organisations are viewing, building and planning their data centres. We see many organisations migrate new data centres to leased co-location facilities and public cloud. When organisations choose to build their own data centre, the facilities need to be more efficient and achieve higher density.
With changes taking place in how technologies are used and valued within the enterprise, there are many shifts I believe will happen in the near future. Here is a summary of the key trends influencing data centres in 2016.
From storage to compute and on-demand access
The previous generations of data centres focused primarily on storage of information and disaster recovery. Geographic diversity was required for backup and data was retrieved on a periodic basis. Now the focus has shifted to analysing and processing data for on-demand access. The rise of mobility and wearable technology creates a requirement for latency that previously has never been seen.
According to a Juniper Research study, the Middle East and Africa regions expect demand for wearable technology devices of eight million units in 2018 and also $19 billion in retail revenue.
The International Data Corporation (IDC) observed that in 2015 there was an increment of 95% of smartphones purchasing with iOS and Android platforms. In addition, according to IDC, the expected growth on mobile penetration in the Middle East region will reach 96% by 2017 as opposed to 94% in 2014.
Consumers and business users alike have an expectation of on-demand access to data from the cloud with the same user experience when accessing data residing on the device. This results in data centres that are far more distributed. The most efficient way for most business to do this is with cloud computing. According to Gartner, the MENA market for cloud computing is expected to grow around 19.3% to total $880 million in 2016.
Where the growth is happening
As stated earlier, data centres will need to be more efficient and achieve higher density. From a service provider and co-location perspective, there will be a large growth in providing distributed computing. The large wave of growth will be in point of presence (PoP) data centres, supporting content delivery networks for service providers as well as promoting network virtualisation and software defined networks. A combination of growth within PoP and co-location will increase the need for interconnecting or peering between service providers.
Bringing compute power to the edge
A big expansion in the coming year will be the idea of moving computing power to the edge of the network. We see service providers wanting to push as many computing resources to the edge of the network as possible to reduce latency by reducing the number of ‘hops’ the data has to take in order to reach the end user.
A large amount of data is shifting from storage to algorithms that manipulate and analyse the data stored. As we use the data, we need to reduce latency.
Ten years ago, in the era of programs, we would pull a program up on our laptops that took some time to load and we would look at it for long periods of time a couple of times a day. Now, we’ve shifted towards an app-driven world where we look at the data hundreds of times a day in shorter durations. Users are starting to feel that data should be predictive and instantly serve up information from the cloud.
To give you an example, look at how social networks launched in the early 2000s. One factor that limited growth during the first few years was the need to increase the number of servers available. Today, a new social network can have instant access to nearly unlimited compute resources on every continent with the use of cloud services. This provides instant scalability, especially for start-ups and tech companies. So naturally, small and medium-sized businesses are going that way.
One aspect playing into the growth of computing power into the edge of the network is modular data centres. We are seeing a trend in hyperscale and service providers deploying in modules at the base of cell sites to bring compute as close to the consumer point of use as possible.
They are deploying an appropriately sized data centre at a geographically correlative location that cuts down latency.
How DCIM and ITSM play into the mix
As you build out these data centres, it becomes a case of how efficient you can make these facilities. You can’t afford to have an inefficient data centre. You need to know exactly where everything is, and how it is being used and powered. Any form of inefficiency in the data centre can be costly and data centre infrastructure management (DCIM) will be paramount in helping keep these data centres running smoothly.
The hype around hyperscale
The scale of demand stemming from the number of consumers doing online shopping has caused several high profile outages. These events will drive organisations to move some of their operations to the cloud in hyperscale data centres. This will give them the ability to flex into a cloud capability when their network becomes stressed. Some phenomena happening within the hyperscale arena include:
The streaming, uninterruptable, low latency services of music, video and information are spurring the growth of hyperscale. Users want steaming information without delay.
More people are moving their compute services to the edge of the network. Data can exist in multiple places to provide static information without latency.
This past year was the year when we heard the trumpeting of wearable technology as we watched a few major technology companies take great strides towards moving away from managing their own data centres and completely into the cloud. It’s exciting to see how the data centre will grow and change over the next few years, starting in 2016. I foresee more businesses expanding via cloud and co-location, while a simultaneous expansion of computing power continues throughout the network and around the world.
