With the advent of Amazon Web Services in 2006 and other large-scale cloud IaaS providers, the cloud computing market changed substantially: platforms were born with scalability, availability and geographical scope never seen before.
It was not a mere change of dimension; the characteristics of these clouds brought a new category, known today as Public Cloud.
This new paradigm has meant a different way to build, deploy and evolve cloud solutions, and the technology sector has led to a new stage, marked by agility, efficiency, and constant innovation. These are some of the features in the center of the disruption caused by major players such as Amazon Web Services, Microsoft Azure or Google Cloud Platform, presented as Public Cloud advantages over other cloud models:
The passage of time makes us forget the complexity of traditional systems and processes, but it is still a determining factor in choosing a cloud model. Building and deploying a basic cloud platform such as Amazon Web Services is an intuitive, efficient and dramatically faster process than in a dedicated Private Cloud infrastructure.
The complexity and value of cloud solutions have shifted from providing physical resources to the design and development of services with the focus on the application.
The size of large clouds becomes an obvious advantage in processes such as the auto scaling. The infrastructure expands automatically and in real time as the demand for resources and the number of users grows. Cloud infrastructure such as Amazon or Google allows advanced technology that orchestrates the process.
The current brevity of life cycle applications would not be possible without these new clouds and technology developed on them. Update of a website several times a day or to complete a mobile application is now a reality thanks to the extreme speed of implementation and deployment that large clouds provide.
The speed and simplicity are the basic advantages of the Public Cloud, which guarantee the operation of services. The infrastructure design of the major public clouds like Amazon Web Services provides high availability through a replica of the platforms in separate data centers.
In this configuration, you may also add advanced levels of security, continuity, encryption and geographical replication to ensure the functioning of the solution to adverse scenarios. Adding additional services, along with good design solution also ensures that performance and end user experience will be optimal in all cases.
These new actors have consolidated the pay per use model, burying significant investments up front and allowing convert CapEx to OpEx technological spending. All resources are provisioned and deactivated on demand, offering a highly tuned on costs control and opening the possibility of testing and deploying solutions.
Besides, most Public Cloud providers offer default volume discounts or resource consumption that increase price competitiveness compared to other alternatives in the IT market.
One of the most important features of this new generation of cloud services and an undoubtedly essential to its success is innovation. Not only is high the rate at which the big players like Amazon Web Services update their portfolio; the possibilities offered to the end customer to investigate, test and improve their technological base are incalculable.
Thanks to the items listed above, the Public Clouds has acted as an enabler and driver of new technological waves such as Big Data or Internet of Things; flexible Q&A and development environments; frameworks and processes automation; agile and work philosophies as DevOps.
Thanks to these and other advantages, the Public Cloud is now the model with the most pronounced cloud adoption curve, generating the largest mass migrations to the cloud and providing great value in hybrid environments.
With appropriate design and management, public cloud companies are able to increase their technological efficiency, expand their business potential and drastically reduce their time-to-market.
