My name is Tim Poultney I am the CEO of Veber, Veber is a UK based hosting service provider that prides itself on selling the best of breed solutions. We were formed in 1999 and we work with small businesses and larger businesses alike. We have extensive experience in hybrid, dedicated and cloud hosting environments.

Today I am here to talk about Understanding the Difference Between Public, Private and Hybrid Cloud and what Veber can offer its clients.

Public Cloud

To start with we’re looking at public cloud, and what most people in the industry will look at as the standard, being Amazon, Microsoft and Google. These businesses offer a very nice platform for developers, administrators to use because everything has a nice GUI, and it’s well documented.

publicLooking at the benefits that most people perceive in these, (public clouds) they have very low upfront costs because you don’t need to buy servers, you have no high Capex costs, they are easily acceptable because all of the documents are just there, you just put a credit card in and you can be up and running. They are relatively cheap to start with, so you can actually bring them up for pennies, pounds, it’s just a very little amount of time, there isn’t a big requirement to get dedicated staff to work with them.

The big disadvantages with public cloud are well documented, and are more around the inflexibility they offer. Things like the choice of hardware – you actually don’t choose the hardware that your server sits on, that’s all decided for you at the backend. They will normally give you a specification, a performance, a virtual CPU’s and an amount of IOPS you can get on the disk. These are relatively small compared to what you would normally look at if you were specking a normal server.

The amount of control that you have in security is one of the primary focuses the IT industry is looking at within the cloud. It is more about the fact that your data is stored in an environment that you don’t control, so you have no idea who is reading your data or who can access your data, we just blindly follow the GUI’s and the setup information on the firewalls, but you actually have no idea what’s happening behind it. The other big disadvantage is that it is a shared platform so you could be sharing your environment with a small web hosting company or a person sending email, or you could be sharing it with a massive company- a news business organisation could be the other user of that server, you have very little idea, so if that company is having a problem, will that slow down your server? Potentially.

On security, one of the biggest questions we actually talk to clients about is the compliance in regulation, ISO standards are pretty much the norm, most businesses try to get them but with amazon and Microsoft they are very hard to achieve the right levels.

The last thing that I bring up with clients is that when you actually use the service, you go into production and you are now a full cloud user, the costs around that can be significant.

Private Cloud

Moving on we are looking at private clouds, the examples of private cloud are much more around an environment that is built to your specification. so with these environments you have a workload that you need to process or deal with, you know what you’re doing, and it will allow you to control costs significantly and actually reduce the operating costs long term compared to the public cloud environments. They are a highly controlled, managed secure environment where we can tune the performance and give you exactly what you need. It’s not a finger in the air to try and work it out.

privateWith most private clouds they’re actually adaptable to growth, so you can grow the environment or you can shrink the environment. But it’s not burstable. The environment doesn’t just grow on its own and shrink on its own.

The big disadvantages is normally there’s a high upfront cost for these environments. So, the service provider that is supplying the environment will have a high Capex cost which he’ll mostly likely itemise over time with an operating cost instead. More resources can be supplied than are actually needed so with a cloud environment offered on the public side you can shrink the size of your server. If you go for a private cloud environment it’s actually hard to reduce the amount of size quickly and reliably for the business because obviously you have a big operating and Capex setup, so they’re going to want to retain the value coming in on that.

There is a lack of sharing of your environment with other people which some people see as good, some people see as bad. If you are suffering problems, niggles, if you’re in something like a public environment many people will suffer it – whether if you’ve got to have the expertise there to work out what’s happening – it can take more time.

Hybrid Clouds

Moving on and looking at the hybrid environments…

Hybrid 2So a hybrid environment is basically where we link the public and private cloud. So you put on the private cloud connections, workflows, known environments that you want to leverage over a long term whether that be your databases, whether that be your processing of bank transactions, your credit card information, things that you don’t want to be in the public cloud. Yet when we look at the public cloud side of all of this we put the things like the front end web servers in the cloud so they can grow significantly.

The benefits… it can be highly scalable-quickly and reliably for clients, it’s much more flexible because obviously if you’ve got a workload that you need to deal with now you can just buy extra resource in the public cloud. It permits enterprises to control the IT settings more than just going for the public cloud so that they can actually control where data flows to and from. They can make sure it’s secure, it’s encrypted, and it works the way they want it to work, and programmers and developers like the flexibility of having the growth on the front end whereas the business likes the fact that they can reduce the costs by having the private cloud back end.

The disadvantages- it is significantly more complex and so if you’re a start-up business you might well not want to look at the hybrid environment to begin with.

Veber’s Approach

So the Veber approach. Veber is a believer that we have to deliver what the client wants, so a lot of our clients will come to us for private cloud environments which we will build out and will help them integrate into a public environment like Amazon or Azure, primarily because as they grow they have different requirements and we understand we can’t supply every piece of this puzzle. So for us our approach is bespoke environments for bespoke businesses, not every business is the same.
