Introduction
What is cloud computing
Cloud computing is the term used to describe the online provision of computing resources such software, storage, and processing power. With a global network of servers and data centres, cloud computing enables users to access these services remotely rather than depending on local servers or personal devices to run apps or store data. Since it offers more flexibility, scalability, and cost effectiveness than conventional IT infrastructure, cloud computing has emerged as a crucial technology for both organisations and people.
History of cloud computing
The idea of time-sharing first appeared in the 1960s as a method to make the most of pricey mainframe computers. From that point on, cloud computing has a long history. As a result, several users were able to share the processing and storage capabilities of a single computer system. Building virtual machines that allowed different operating systems to coexist on a single physical server became practical in the 1990s as virtualization technology developed.
Google CEO Eric Schmidt originally introduced the phrase “cloud computing” to characterise his company’s strategy for providing computer services over the internet in 2006. The rise of the internet, the prevalence of mobile devices, and the necessity for companies to extend their IT infrastructure fast and affordably were some of the elements that sparked the development of cloud computing.
The majority of services were first provided by a small group of businesses, including Amazon Web Services, Microsoft, and Google. These organisations created cloud platforms that let corporations rent computer resources on a pay-as-you-go basis rather of making costly hardware or software investments.
Evolution of Cloud Computing
The first wave of cloud computing
The term “first wave of cloud computing” describes the early years of the cloud computing period, which began in the middle of the 2000s and lasted until the beginning of the 2010s. The use of cloud computing technology increased significantly during this time, both among individuals and enterprises.
A number of significant players in the cloud computing market, including Amazon Web Services, Microsoft Azure, and Google Cloud Platform, emerged during the first wave of the technology. These businesses offered a variety of cloud-based services, including software as a service, platform as a service.
The creation of new cloud standards and technologies like virtualization, containerization, and OpenStack also marked the initial wave of cloud computing. These innovations contributed to the increased scalability, flexibility, and effectiveness of cloud computing.
The second wave of cloud computing
The current phase of cloud computing, which started in the middle of the 2010s and is still developing today, is referred to as the second wave of cloud computing. Focus on artificial intelligence (AI), machine learning (ML), and data analytics, as well as an emphasis on the cloud’s potential to support business digital transformation, are characteristics of this era.
The necessity for organisations to use cutting-edge technologies like AI and ML, as well as the rising need for data-driven insights, are what are driving the second wave of cloud computing.
