Cloud Managed Services and Deployment Models
One of the most common questions Teck Genius gets from its customers is based around the different cloud “types” and how it can be a confusing process to go through. Choosing cloud managed services is one thing, but actually making that first leap requires the right partner to be working with you and for you. More often than not, the keep-it-simple narrative gets lost in translation and before you know it, you have numerous options and ultimately wasted time and potentially cost.
So, let’s start with the cloud deployment models. There are essentially three cloud models that you can utilise, and they can be described as Public Cloud, Private Cloud and Hybrid. Each offers its own benefits and limitations and the one that is best suited for you and your business can differ depending on the requirement. Let’s look a bit more into each model.
A public cloud is a deployment model that is offered to more than one person/company by a cloud service provider. Like pretty much all cloud services, a public cloud runs on servers that are hosted from a data centre are or usually owned and operated by the cloud service provider. Think of a public cloud of a house with multiple rooms. You don’t own the whole house or the room – you merely rent a part of it for a small amount of time.
A private cloud is a deployment model that is offered solely to you for your dedicated own use. It generally has a contracted time and, in that time, you can run all your services on it with the comfort of knowing that it will not be shared. Think of a private cloud like a leased apartment. You buy the apartment on a leased basis for 10 years and in that time only you can and will use it.
A hybrid cloud is a model that is provided across two cloud platforms. For example, you may have services running across two cloud services such as Private Cloud (VMware) and Public Cloud (Azure or AWS). You have the best of both worlds and limit risk by not being aligned to only one cloud.
The deployment model that you select will largely depend on what services/applications you want to consume. To get to the correct decision requires a few questions that need to be answered and then selecting a suitable provider of the model.
So where does Cloud Service Models come into this?
One of the challenges Teck Genius sees with companies is ensuring that the deployment and service model are aligned to what they actually need in terms of functionality, capability and security. Whilst the cloud deployment model decision can be fairly straight forward (and is likely aligned to inherent IT Support capability, experience, cost, to name a few ) the decision on which Cloud Service model to take is largely down to the commitment to the cloud journey you want to make. There are ultimately three services you can choose form. Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS). Let’s look a little deeper into each service models:
> Infrastructure-as-a-Service (IaaS)
This cloud service model is provided by the vendor and allows you to access and consume servers, storage and networking on a specific platform. It is essentially rentable hardware and infrastructure services which you can scale up and down, as and when required. It is very popular for those that want to be able to run their own infrastructure services and applications and have the skills to do so without worrying about the underlying hardware.
> Platform-as-a-Service (PaaS)
This cloud service model is provided by the vendor and allows you to access and consume certain application-centric services including the likes of a database. As a user you don’t have to worry about the hardware and the underlying operating system, and nor do you need to be concerned with the overlaying service you consume. An example of PaaS would be managed SQL service.
> Software-as-a-Service (SaaS).
This cloud service model is provided by the vendor and allows you to access and consume full software application services. You generally are not burdened with the hardware, operating system, platform and its inherent dependencies. A good example of a SaaS would be Outlook online or Office 365.
