Stephen O'Herlihy, Chief Technical Officer at PFH Technology Group recently spoke to Quinton O'Reilly of the Sunday Business Post regarding the Cloud and how it can meet it's potential.

The hybrid model doesn’t just give you the best of both worlds; it also means you have to consider how it affects staff and processes. For Steve O’Herlihy, chief technology officer at PFH Technology Group, you need to make sure you’re not creating more work for yourself by moving.

As mentioned earlier, not all services play nicely with each other so you may have to deal with them individually instead of having an overview.

“Certainly from the majority of business, it’s about leveraging their existing investments and that’s investments in on-premise solutions, not just the systems but also the people and processes,” said O’Herlihy. “When you move the cloud. your people think of technical feasibility, how quick or fast it is, how it runs and availability.

“But what about your people involved and how does that impact the business? What happens to those people in those roles? I think that’s become very apparent in recent times.

“By example, if you have a series of workloads on-premise and you move some to the cloud, you’ve now doubled your management overheads, your footprint has doubled in two very different platforms

“The likes of Azure and AWS are very different to what you would typically have in a traditional environment so when it comes to optimising, absolutely drive efficiencies, but give me something where I can see all of my workloads across multiple workloads and on-premise, give me something where I have financial transparency.”


The same lack of knowledge can be filed under cost too, according to O’Herlihy. There are many different models in place and it’s probably more apparent when you dive into the cost of it.

“If you were to dig under the covers and look at the term cloud, it’s a very, very broad term used to describe what’s used to run a workload,” he said. “If you were to describe the characteristics of cloud, they’re basically things like a consumption model, pay as you go, and more importantly, you don’t pay with what you’re not using which is important.

“The whole consumption model — if you’re describing availability, security and reduced management overheads — when you start delving into this, the answers are those characteristics vary depending on the cloud offering.

“Typically you would have a situation where I would go into a costumer and our CIO or senior management team has made a decision that it’s cloud-first and then only start to explore what is the reasoning for that.”
