History of Cloud computing

Introduction: History of Cloud computing. Cloud computing, a paradigm that has revolutionized how businesses and individuals utilize technology, has a history spanning several decades. Its origins can be traced back to the 1960s, with the concept evolving to become the ubiquitous force it is today.

The idea of cloud computing can be delineated back to the 1960s, with the emergence of time-sharing systems. During this era, multiple users could access a single computer simultaneously, sharing its resources. This laid the groundwork for remote resource sharing, a fundamental aspect of cloud computing.

In the 1970s, the development of virtualization technology took shape. Innovations like IBM’s VM system allowed multiple operating systems to run on a single physical machine, enhancing resource utilization and flexibility. Nevertheless, it wasn’t until the 1990s that the term “cloud computing” gained traction.

History of Cloud computing in the late 1990s

The 1990s witnessed the rise of telecommunications companies offering virtual private network (VPN) services. These networks allowed organizations to connect and share data securely over the Internet, setting the stage for the broader cloud concept.

Additionally, the dot-com bubble led to the creation of Application Service Providers (ASPs), who offered software and services over the Internet, laying the foundation for Software-as-a-Service (SaaS) models.

The cloud gained popularity as companies better understood its services and utility. In 1999, Salesforce became a famous example of successfully using cloud computing. He used it to introduce the idea of ​​using the Internet to provide software programs to end users.

The program (or application) could be permitted and downloaded by anyone with internet access. Companies can buy software on-demand, cost-effectively, without ever leaving the office.

Cloud computing in the early 2000s

The early 2000s marked a turning point with the emergence of Amazon Web Services (AWS) in 2002. AWS introduced the infrastructure-as-a-Service (IaaS) concept, allowing users to rent computing resources on demand. This move transformed how businesses managed their IT infrastructure and paved the way for other cloud providers to follow suit.

As the 2000s progressed, cloud computing gained momentum. Google launched its suite of productivity tools as Google Apps in 2006, showcasing the potential of cloud-based software. 

In 2007, IBM, Google, and several universities united forces to design a server farm for research projects requiring fast processors and large data sets. The University of Washington was the first to sign up and use resources delivered by IBM and Google. Universities rapidly realized that computer experiments could be done quickly and cheaply if IBM and Google supported their research.

Because much of the study concentrated on issues in which IBM and Google had interests, they also benefited from the arrangement. 2007 was also the year Netflix launched its streaming video service using the cloud and furnished support for “binge-watching.”

In 2009, Salesforce.com introduced the concept of Platform-as-a-Service (PaaS), allowing developers to build, deploy, and manage applications without the complexities of the underlying infrastructure.

The introduction of these varied cloud service models fueled rapid adoption and innovation. Businesses increasingly recognized the benefits of cost savings, scalability, and flexibility that cloud computing offered. This led to a surge in cloud providers, offering various services catering to different needs.

2010 and Beyond

Although private clouds were introduced in 2008, they needed to be developed and unpopular. Poor security concerns in public clouds were a strong driving force encouraging the use of private clouds. In 2010, companies such as AWS, Microsoft, and OpenStack developed private clouds that were quite functional. The mid-2010s saw the mainstreaming of cloud computing.

Microsoft Azure gained prominence, becoming a strong competitor to AWS. Meanwhile, industries like healthcare and finance, previously hesitant due to security concerns, began migrating sensitive data to the cloud, thanks to enhanced security measures and compliance standards.

Containerization technology, with Docker as a frontrunner, gained traction around this time. Containers facilitated efficient deployment and management of applications, further streamlining the cloud development process.

The notion of hybrid clouds was introduced in 2011. A considerable interoperability capacity between the private and public clouds and the power to move workloads back and forth between the two clouds is required. At the time, few businesses had systems capable of doing this, although many wanted to because of the tools and storage the public cloud could offer.

In 2011, IBM presented the IBM Smart Cloud framework, sustaining the Smarter Planet (a cultural thinking project). After that, Apple launched iCloud, which focused on storing more personal information (images, music, videos, etc.). Also, that year, Microsoft started promoting the cloud on television, making the general public conscious of its capability to store pictures or video with an accessible permit.

Oracle presented Oracle Cloud in 2012, offering three core offerings to businesses, IaaS (Infrastructure-as-a-service), PaaS (Platform-as-a-service), and SAAS (Software-as-a-Service). -A-Service). These basics fast evolved the norm, with some public clouds offering all these benefits while others concentrated on just one offering. Software as a service became quite popular.

By 2014, cloud computing had developed its core features, and security had become a significant concern. Cloud security has become a rapidly growing service due to its importance to consumers. Cloud security has advanced significantly over the past few years and offers protection comparable to traditional IT security systems.

This includes protecting critical information from accidental deletion, theft, and data leakage. Security is, and always will be, the primary problem of most cloud users.

Now, one of the primary users of cloud services is application developers. In 2016, the cloud started to shift from developer-friendly to developer-driven. Application developers began to take full advantage of the tools available to them from the cloud.

A large number of services try to be developer-friendly to attract more users. Realizing the demand and the profit potential, cloud vendors developed (and continue to grow) tools that app developers want and need.
