How to Cloud – Public, Private or Hybrid?

Before moving to the Cloud it’s important to evaluate what different Cloud technology solutions offer and the different Cloud models and their offerings in line with your business strategy. Currently, there are 3 primary cloud models, namely Public Cloud, Private Cloud, and Hybrid Cloud.

Let’s help you understand the nuances of each and help you get a better idea about which model might be best suited for your enterprise requirements:

What Are They?

  • Public Cloud: A Public Cloud is the most basic and simple implementation of the cloud, where a cloud service provider provides different kinds of resources, such as applications (SaaS), Infrastructure (IaaS) or an entire Platform (PaaS) to customers. This typically works on a pay-per-usage model, where the customer pays the service provider for the services used. Microsoft Azure and AWS are the two most common examples of Public Clouds.
  • Private Cloud: A Private Cloud is similar to an on-premise setup with the benefits of a cloud-based model. The private cloud is set up on-premise on infrastructure owned by the company, but provides for quick ramping up and down of capacity and installation of virtual machines for optimum utilization of the available resources. VMWare is a common Private Cloud service enabler.
  • Hybrid Cloud: A Hybrid Cloud allows customers to enjoy the benefits of both the Public Cloud and the Private Cloud. Most organizations have an IT landscape which are too complicated to go for either a completely Public Cloud, or Private Cloud based approach. Budget constraints too may prevent companies from implementing a Private Cloud model where data security concerns as well as security requirements may prevent them from a completely Public model. In such a case, a Hybrid model allows the creation of a Public as well as Private cloud to fulfill both requirements.

    A Hybrid Cloud based approach is typically implemented with the help of a system integrator who can help integrate cloud systems from public and private cloud service providers. Microsoft Azure is quickly gaining traction in this space. Embee is a leading Cloud System Integrator with a Pan-India presence.

How Is the Market Doing? 

As per RightScale’s 5th Annual Cloud Survey for 2016, 95% of all respondents are using cloud computing in some or the other model.

The increase in the adoption of private cloud has increased the overall percentage of respondents using a Hybrid Approach to a very high 71% as compared to 58% in 2015.

As is clearly, Hybrid Cloud is the current model of choice.

While 89% of the respondents are using Public Cloud, the adoption of Private Cloud has also risen to 77% in 2016 as compared to the 63% in 2015.

Which Model Is Right for Me? 

A one-size fits all approach doesn’t work for Cloud Computing. It can never be a simple THIS or THAT answer, there’s a need to for an organization to first evaluate their requirements internally and take the help of a system integrator and strategic partner such as Embee to answer basic questions such as analysis of current applications, the applications which will be moved to the cloud, performance requirements, and regulatory and data security constraints. Once these questions are answered and IT budgets are analyzed, it becomes easier to choose the correct model.

However, below are examples of the typical kind of companies that use the different models: –

  • Public Cloud: Organizations that need to quickly ramp performance and has fluctuating capacity and a limited resource pool for the investment. Typically suited for basic SaaS applications like E-Mail, and in an environment where data and applications are not very critical or susceptible to attack and theft.
  • Private Cloud: Best suited for organizations where applications and data are mission critical and bound by restrictions. A typical example of this would be Government organizations, where it’s not allowed for data to travel outside the company’s premises. For example, AWS’ shared drive space platform is not compliant with HIPAA requirements, which means it can’t be used in sectors like Healthcare and Nuclear. In such situations, investment in a Private Cloud system with optimum security is ideal.
  • Hybrid Cloud: Most modern organizations are unable to make a decision between taking a completely public or private cloud approach. Transferring storage and computation to the public cloud definitely has its cost advantages, but some mission critical data and applications must remain on premises. A hybrid cloud model makes perfect sense in such a scenario. It is also highly suitable for organizations that are just starting with the cloud, because it allows them to run instances of applications on the cloud to compare performance and finalize their cloud strategy.
