Exploring the hybrid cloud | A podcast
Config Cast, Episode 1
The very first edition of the Config Cast coming from the London and New York Sweagle offices. This hybrid cloud podcast episode is a discussion about the biggest issues of running applications in the cloud.
Everyone’s talking about the hybrid cloud
Everyone seems to have been talking about the cloud for at least ten years. And adoption hasn’t taken off at the rate you might expect. Why is that?
In theory, it’s appealing
Firstly, moving to the cloud in theory seems easy and very appealing. But if you’re a large enterprise it’s actually massively complex. There’s a lot of hassle involved because you have a multitude of old and new systems. And if you’re in a regulated industry, you’ve got a high degree of risk of where you expose your data. So, it’s not a trivial decision to move to a hybrid cloud infrastructure. It takes a long time for organizations to come to that decision.
It’s not an easy decision
Secondly, when they get there, there’s a massive push to make that transition happen as soon as possible. So, in the case of complex organizations, it takes a long time to come to the decision. But once it’s made, people are under a huge amount of pressure to do it quickly.
Legacy applications vs modern applications
On the one hand, if you’ve got a modern application and it’s built in microservices, then it’s relatively easy to move it into the cloud. You get all the benefits of the cloud because you can process different jobs at different times and use the elasticity of the cloud.
On the other hand, if you’ve got a legacy application, it’s like a big lift and shift. So as a big organization, you probably haven’t got that choice to decide whether you’ll leave these on-prem or you’ll put these in the cloud. It’s usually the case that it’s all going to the cloud. So you have to figure out how to put the whole lot in there.
As a result, you can move the easy things across to the cloud first – and relatively quickly. However, in large enterprises 90% of your applications are all legacy applications. In that case, you have to work out how you’re going to fix that.
For example, if you’re an architect, and you’ve been told to figure out how you are going to migrate to the cloud, there will be a lot of head scratching going on. How on earth do you move a 25 year old application to the cloud? And, ultimately, if you don’t move everything to the cloud, you’re probably not going to get the financial benefits of a cloud infrastructure.
What’s the role of AI and machine learning?
From a machine learning point of view, does automation and the lack of human intervention reduce the risk that people feel from moving to the cloud?
When you start to talk about artificial intelligence and machine learning, it’s more than real. It’s very usable in a lot of cases. Although, it’s possibly not the magic button that everyone hoped it would be. However, it’s certainly a way to accelerate what you’re doing.
