How to Choose and Implement the Correct Cloud Model


New Member

Choosing the right cloud model for your organization is critical to your business practices. It can, however, be quite challenging. This is because your business needs are unique and you need a cloud model that can meet these unique needs.

According to a study by cloud automation tools vendor, RightScale that was published on the Forbes website, more companies are adopting cloud computing in one form or another. The study that collected views from 80,000 respondents, most of whom are not RightScale customers, found that up to 93% are experimenting with IaaS.

The same study also shows that the number of companies utilizing the hybrid cloud grew from 74% in 2014, to 82% now. 63% of these surveyed organizations were using the private cloud and 88% utilized public cloud models.

Are you wondering where you fit in? In order to pick the right model for you, you need to understand some of the factors that cause a company to pick one model over another.

Factors to Consider when Choosing a Cloud Model
  • Control – you have to find the right balance between control and convenience. With public clouds, you often don’t have to worry about certain things like maintenance, but your options will be limited. With private clouds, you have more freedom to choose how everything works and whom to work with.
  • Security – if you have highly sensitive materials you probably want to go with a private cloud. This is because as much as public clouds are somewhat secure; your data could still land out in the wrong hands.
  • Scalability and flexibility – you will find that public clouds have more options when it comes to scalability and flexibility. Private clouds can however achieve the same Scalability and flexibility standards that public clouds can. You may just need to work a little harder and pay close attention to detail to get tangible results.
  • Management – do you want to manage your cloud or would you rather delegate this task? A managed cloud will ease the burden of cloud deployment for your organization. If you would like a little more time to do other things, a managed option is a good choice.
Now that we have an idea of what to consider when choosing a cloud model, let’s look at the different models available. We can then select and implement a model based on individual organization needs.

Private Cloud Model
In this model, you as a business or organization manage your own cloud deployment. This is the perfect choice for you if you want to maintain control and management of your access to data. It can, however, be very costly in terms of monetary investment and time investment to implement the private cloud model. This is why only large organizations can implement this model and explains why only 63% of the surveyed organizations use the Private cloud.

Public Cloud Model
In this model the cloud service provider manages the cloud and security on your behalf. While they are cost-effective and easy to implement, they only provide a reasonable level of security. They are therefore not ideal for high level security data. They are ideal for you if you don’t want to have to worry about infrastructure requirements and other management issues.

Hybrid Cloud Model
With the hybrid model you get the capabilities of a public cloud with the Security and control of a private model. It is essentially the best of both worlds. In fact it is very likely that hybrid models may outpace and replace both public and private models. This model will give you the advantages of both the private and public clouds while limiting the disadvantages.

The Hybrid cloud model has been known as the new Private cloud. It is not surprising that the number of hybrid cloud users has risen to 82%. In fact it is expected to keep growing in the coming years.

Matching technology to your business needs is always complicated. When it comes to the cloud, understanding the different “as a service” models is important to make sure you receive the benefits you’re hoping to get by using this technology.

Software as a Service
Software as a Service (SaaS) is perhaps the simplest cloud model. In SaaS, you are a subscriber to an application. The application vendor hosts the application on their own site and stores all the data at their site as well. You have no responsibility for supporting the hardware or for making sure there’s sufficient storage for your data. You are also not responsible for applying any patches or updating the application. However, you are responsible for ensuring that user privileges are granted only to authorized employees.

Infrastructure as a Service

With Infrastructure as a Service (IaaS), the cloud provider gives you a virtual machine and storage, both sized according to your requirements. You’ll also get basic networking services. The cloud provider handles the hardware support. You are responsible for all application support, usually including the operating system. The cloud provider will ensure the physical facility is secure, but you’ll need to handle the security of your virtual machines and your applications.

Platform as a Service
Platform as a Service (PaaS) provides you a virtual machine and frameworks needed to deploy and run applications. The goal is for these services to allow your internal developers to write, test, and deploy code faster, often using a “DevOps” methodology. In some ways, PaaS is like SaaS, where your developers are the subscribers to the development software.

All three of these models offer agility and scalability. You can add users and resources on-demand, as you need them. There can be large cost savings, as you don’t need to have spare capacity purchased and provisioned in advance.

Software as a Service is ideal when there’s a vendor product that provides the exact functionality you need or the application isn’t a core business function. Platform as a Service is the right choice when you need to build custom applications but don’t want or need to handle the lower-level infrastructure that supports them. Infrastructure as a Service gives you the most control and the most flexibility to tailor your cloud environment to your exact specifications.

Everything as a Service
In addition to the three “standard” cloud models, you’ll find many other products offered “as a Service.” This includes Database as a Service (DBaaS), Disaster Recovery as a Service (DRaaS), Desktop as a Service (DaaS), Identity as a Service (IDaaS), Security as a Service (SECaaS), and more. These offerings provide access to specialized functions and maybe appropriate choices to meet specific technology needs.

Adopting and Adapting to Cloud
Whichever cloud model you choose, it will take time to adapt to it. You’ll need to migrate your existing technology to the new cloud platform and train your team to monitor and manage it. It’s often helpful to get support from a managed services provider with expertise in the cloud to make sure your new environment operates properly and you get the benefits you expected.
