With the unbeatable flexibility it offers, the acceptance of Cloud Computing is growing steadily. The agility and cost benefits offered by the cloud makes it a viable choice for large and small businesses alike. By eliminating the need for physical servers and storage systems, clouds allow businesses to save on high initial investment and focus more on operating expenses, while also giving them a free-hand on increasing and decreasing capacity as per volume of business. The demand for Cloud Computing solutions is also helping drive the demand for Cloud Computing specialists and cloud computing courses online, that are key for organizations to implement, support, and develop applications on their cloud environments.

The concept of cloud computing had its humble beginnings within the development of virtualization and mobile technologies, and has developed into several frameworks and delivery models as discussed below:

Public Cloud:

The most common and the most cost effective type of cloud opted by most businesses is the public cloud. A few years back, this was the one type of cloud that was ruling the industry due to the ease of setting up a public cloud and the lower cost incurred. You only have to pay for what you use and of course you have the scope to expand.

  • The Good:
    • Scalability is indeed the first good thing about public cloud.
    • Cost – it requires the lowest investment costs among the other types thus making it ideal for startups and small businesses.
    • Ease of use and flexibility.
  • The Not So Good:
    • Given the cloud is public and there are several other businesses and users accessing the same cloud, security aspect is the first main vulnerability of this system.
    • Reliability is not the best in the segment. There have been instances of reported outages of public cloud impacting all the involved businesses.

Private Cloud:

Though more expensive than the public cloud, this offers better levels of control and security. There would be a private network on which your infrastructure is maintained. Your organization would be the sole party accessing this portion of the private cloud. These private clouds could either be located on premise or could be hosted externally by the cloud service provider.

  • The Good:
    • You exercise better control over the cloud.
    • Private clouds are more secure making them ideal for those businesses where data security is the prime requisite.
    • The resiliency the private clouds offer.
  • The Not So Good:
    • These are higher investments than the public cloud. When you opt for on premise solution, the cost increases further.
    • You might not gain universal accessibility as you would with public clouds.

Hybrid cloud:

The balanced approach that most organizations have learned to adopt to get the best of both worlds is by going hybrid. This is done by segmenting and prioritizing the data and storing the more critical ones on the private cloud while having a public cloud to store the rest of the data. This type of infrastructure aims at making use of the benefits of both public and private clouds as and when required.

  • The Good:
    • As you have a public cloud to hold the less critical information, you have the option to expand and the flexibility that comes with it.
    • This would also bring the scalability of the public cloud.
  • The Not So Good:
    • This is not a wide-spread system. The scope for the improvement of hybrid cloud infrastructure is pretty vast.
    • As it has both public and private clouds in the picture, just like it offers the best of both types, the associated drawbacks of both comes along too.

With 95% of all respondents from a 2016 RightScale survey stating that they use Cloud Computing in some model or the other, the popularity of the platform can’t be ignored. Cloud service providers such as Microsoft Azure, Amazon Web Services, and Google Cloud are constantly plugging in resources to develop their offerings further, leading to even faster growth for the entire sector. With such kind of growth, it’s no wonder that Cloud Skills are among the top 10 most in-demand skills as selected by LinkedIn 2 years in a row.
