Earlier this month, we listed the 5 areas of technology that former Fortescue Metals CIO, Vito Forte, believes will soon disappear.\nForte also discussed the 5 areas of IT that are on the rise \u2013 growth areas that technology chiefs need to think about \u2013 at last month\u2019s CIO Summit in Perth.\nThey are:\n1. The rise of the service broker\nUse your knowledge and experience to bring the right things to the right people, said Forte.\n\u201cYou are fundamentally becoming a broker of capability \u2013 you don\u2019t need to build and run [systems] anymore,\u201d he told attendees.\n\u201cYou need to deliver and service. So that means what you are doing is relying on others to do that sort of thing and making sure that they actually create and add the value that you and your organisation really needs,\u201d he said.\nForte said a CIO\u2019s value proposition is his or her understanding of what the business is about and mapping their knowledge and experience to the capability.\n\u201cIs it going to be perfect? Does it need to be perfect? No, because it\u2019s going to change again. So what you need to be is adaptable and flexible \u2013 this is where your value is because aren\u2019t you in this industry to be a change agent?\u201d he asked.\n2. The rise of software-as-a-service (SaaS)\nInfrastructure-as-a-service (IaaS) is a means to an end, it\u2019s not where the future is and is a way for people to understand the \u2018as-a-service\u2019 mentality,\u201d claimed Forte.\nThe SaaS market \u2013 which will be worth $142 billion globally by 2020 \u2013 is where it\u2019s at, he said. This compares to a $5 billion IaaS market and $4 billion platform-as-a-service market, according to research by Forrester.\n\u201cAre you taking advantage of this? Why maintain legacy [systems]?\u201d he asked.\nForte believes organisations are still focusing on the 98 per cent and forgetting the 2 per cent where value is added. Moving to SaaS infrastructure enables IT teams to focus on high value tasks, he said.\n\u201cWe believe all organisations are different \u2013 that they fundamentally process things differently because that\u2019s where their value lies. No it doesn\u2019t,\u201d he said.\n3. The rise of identity-as-a-service (IdaaS)\nForte pointed to new service offerings that allow companies in industries that deal with very confidential information to encrypt all data right down to end point devices.\n\u201cThese are services that are now appearing for different types of industries. So the rate of change in this space is going to grow exponentially as we see the embedding of security in applications and capability rather than it being this thing that sits on the side that we then have to try and integrate,\u201d said Forte.\n\u201cNormally, if this doesn\u2019t work out, we then build a walled garden and throw everything in the middle and set all the troops up around the outside with bows and arrows hoping to keep the bad guys out.\u201d\nIdentities are no longer the domain of a single organisation, said Forte. There\u2019s a lack of a perimeter for organisations that are dealing with a large distribution of customers, employees and partners.\n\u201cThe key thing here is around identity. Do we put all these people in our directories?\u201d he asked. "How do you validate identities? Do you ask people to give you a 100 point check before you give them an email account? Why would we do that?\u201d\nForte said that most consumers are now logging into many services with their Facebook, Google+ or LinkedIn IDs.\n\u201cWhy don\u2019t we take advantage of that?\u201d he asked. \u201cThis will reduce the reliance on a whole bunch of internal infrastructure to work out \u2018who is who in the zoo\u2019,\u201d he said.\nHe said organisations \u2018sort of get this wrong anyway\u2019 so there\u2019s an opportunity to learn from consumer-oriented capabilities.\n4. The rise of ArcOps\nAlthough DevOps \u2013 a concept aimed at improving interaction between app developers and IT operations staff \u2013 provides agility and helps to speed up application deployment, IT teams need to start earlier at the architecture level, said Forte.\n\u201cArchitecture is about strategy execution and that\u2019s it. So if you are not executing on those particular elements, and following it through to see if you have architected something that actually delivers value, why are you doing it in the first place?\n\u201cTo deliver with velocity, we need to architect for operations, not just develop. Architecture is not an island of perfection,\u201d he said.\nHe questioned how a chart with 75 million lines that is only understood by one person creates value.\n\u201cWho takes ownership of delivering that? The conversations I have heard in the past have been: \u2018Well the reason that failed is because you, being operations, didn\u2019t understand what I designed.\u2019\n\u201cWell whose fault is that? Aren\u2019t we on the same team?\u201d he said.\n\u201cSo making that end-to-end capability responsible from the architecture piece right through [to completion] is really important and can drive a lot more value.\n\u201cIt does upset the architects though but that\u2019s OK \u2013 that\u2019s the whole point of disruption,\u201d he said.\n5. The rise of the \u2018sharing\u2019 economy\nForte believes we have barely scratched the surface of the potential of the sharing economy currently driven by innovators like Uber, Airbnb and Airtasker.\nThe disintermediation that has occurred with companies like Uber means we are \u201cbasically excising infrastructure\u201d, he said.\n"Australia Post\u2019s biggest challenge is trying to work out who is going to \u2018do an Uber\u2019 on them. That\u2019s what they are petrified about. They haven\u2019t worked it out yet.\u201d\nHe questioned why Australia Post has its own delivery trucks or why it can\u2019t join forces with supermarket giants to deliver to customers.\nHe cited a partnership between Audi, DHL and Amazon as an example of an innovation in this sharing economy. Amazon is testing a postal service that will see DHL staff deliver parcels to customers' cars.\n\u201cAudi will give Amazon access to your boot of your car for a short period of time for them to deliver your parcel,\u201d Forte said. \u201cThis costs Amazon nothing.\u201d\nGoogle is just about to start its autonomous car trials in California, said Forte.\n"That's about vehicle-to-vehicle communications, cars are talking to each other now," he said. "What people don't realise is that they are talking to each other in terms of positioning, velocity and other aspects of the driving experience.\n"But if those networks are in place and you've got a connected mesh of things with CPU and processing power, what else can they do? Can they carry other data? Can they take data off sensors in the road and transmit it to a Department of Transport? Can they take data off trains and allow it to be transmitted somewhere else?\n"It's that sort of stuff that starts to come out when these sorts of things start to happen," he said.
