Its advantages go beyond traditional computing methods and go beyond grid computing and others. A key moment in the maturation of cloud computing occurred in 2006 when Amazon introduced the first cloud services. Hong Kong is particularly suitable for the deployment of cloud services due to its extensive daily data processing across various sectors. Despite the slow start, there are strong signs that Hong Kong\'s local companies are gearing up for significant growth in cloud orders. In the field of research, cloud computing has reached the pinnacle of computing. Its far-reaching implications, especially when dealing with big data, make it an important consideration. A cloud service that fulfills the long-held dream of treating computing as a utility has the potential to transform a significant part of the IT industry. This not only increases the appeal of software as a service, but also reshapes the landscape of IT hardware design and procurement.
In the modern panorama of the 1960s, Joseph Carl Robnett Licklider pioneered Cloud Computing, laying the inspiration via his groundbreaking paintings on ARPSNET. His imaginative and prescient aimed to create a unbroken surroundings wherein human beings should have interaction with facts from any place at any time. Fast ahead to 1983, while CompuServe added a pioneering concept, granting customers a restrained but giant quantity of disk area to keep documents in their choosing.
Much like actual clouds fashioned via way of means of water molecules, the term 'cloud' in cloud computing encapsulates a group of networks.
Users now have the remarkable flexibility to effects hire diverse cloud computing modalities as needed, disposing of the want to spend money on and control their bodily infrastructure.
Rather than putting in place their infrastructure, customers frequently select the ease of middleman provider carriers in cloud computing. This pay-as-you-move version guarantees that customers handiest pay for the precise offerings they make use of . Furthermore, the workload distribution in cloud computing is dynamic, taking into account a greater green allocation of assets and decreasing the weight on neighborhood computer systems while strolling programs . Consequently, the call for hardware and software program on the user's cease is substantially mitigated, with simply an internet browser, like Chrome, being the gateway to gaining access to cloud computing offerings.
Key pillars of cloud computing encompass 3 number one offerings: Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS) . Everyday programs like Facebook, YouTube, Dropbox, and Gmail constitute tangible examples of the way cloud computing has seamlessly included into our each day lives. The adoption of cloud computing in businesses is on a meteoric upward thrust because of its inherent scalability, flexibility, agility, and simplicity. As this generation keeps to evolve, it reshapes the manner we technique and make use of computing assets withinside the virtual age.
II. EVOLUTION OF CLOUD COMPUTING
In a 1960 speech at MIT, John McCarthy envisioned computing being sold as a utility like water and electricity. Taking a big step in 1999, sales staff began distributing applications to customers through a user-friendly website . In 2002, Amazon launched Amazon Web Services, which provides storage and computing services. By 2009, industry giants such as Google, Microsoft, HP and Oracle started offering their cloud services . Today, cloud computing is seamlessly integrated into everyday life thanks to widely used services such as Google Photos, Google Drive and iCloud. In the future, it is clear that cloud services will become the basic needs of the IT industry.
The cloud service consists of three important parts:
III. SOFTWARE AS A SERVICE (SAAS)
Software as a Service (SaaS) describes the delivery of applications over the Internet, allowing users to access computers without local installation. This approach frees users from the hassle of managing software and hardware as they do not need to be purchased, maintained or upgraded. All you need is a simple internet connection for easy access. Popular examples of SaaS are Microsoft Office 365 and Google Apps.
In the world of cloud computing, SaaS extends its reach by offering software to users online, through a subscription model. This template is especially useful for applications that require extensive web or mobile functionality, such as mobile sales management software. Managing SaaS from a central location can reduce the burden on your business, especially for short-term projects.
There are many benefits of cloud computing.
IV. ADVANTAGES OF SAAS
Unlocking the potential of advanced applications has never been easier thanks to Software as a Service (SaaS). When delivering SaaS applications, the need to invest, purchase, upgrade or manage hardware, middleware or software becomes a thing of the past. This accessibility extends to complex business applications such as ERP and CRM, bridging the affordability gap for organizations that do not have the resources to acquire, deploy and manage the necessary infrastructure and software on their own.
The financial benefits of SaaS are clear in its distributed cost model, which ensures that users pay only for the services they actively use. In addition, the flexibility of SaaS services, which automatically adapt to usage levels, means tangible savings. This dynamic model proves particularly useful for organizations dealing with changing demands.
User interaction is simplified with free client software. Most SaaS applications can be run directly from a web browser, eliminating the need for users to download and install additional software. While certain applications may require plug-ins, this approach streamlines the user experience and removes the burden of purchasing and installing specialized software.
Mobilize your workforce effortlessly with a SaaS service that enables users to access applications and data from any Internet-connected computer or mobile device. This eliminates the concern of developing applications for different platforms, while the service provider deals with complex computing environments. The security issues of mobile data processing are also addressed by a carefully selected service provider that ensures the security of data regardless of which devices they are used.
V. TYPES OF CLOUD COMPUTING
A. Public Cloud
A public cloud is a service provided by third parties over the public Internet. It is available to all users and payment is based on certain services consumed. Public clouds are designed for widespread use.
B. Private Cloud
On the other hand, private clouds provide computer services over the Internet or private networks only to selected users or organizations. These clouds prioritize higher security and privacy, achieved through firewalls and internal hosting, creating a controlled work environment.
C. Hybrid Cloud
Hybrid cloud combines public and private cloud models. In this configuration, each cloud (public and private) can be managed independently, while data and applications can move seamlessly between the two clouds. This approach allows organizations to leverage both public and private clouds and optimize their cloud strategy.
VI. BENEFITS OF CLOUD COMPUTING
A. Cost Saving
In, cloud services, users pay only for the services used, which leads to significant savings. The beauty lies in the fact that users do not have to invest in purchasing and managing infrastructure, so it is an economically reasonable solution for companies that want to optimize their consumption.
Cloud computing stands out for its flexibility, which allows companies to quickly scale their operations. Whether a business is growing or declining, cloud computing provides the necessary adaptability to quickly adjust hardware and resources. This ensures that companies can perfectly adapt their computing resources to their ever-changing needs.
C. Better Security
Security is a top priority in cloud computing. Applying data encryption, strong access control, key management and information security together creates a stronger environment. Users can be sure that their data is treated with utmost security, creating confidence in the protection of sensitive data.
VII. DRAWBACK OF CLOUD COMPUTING
A. Internet Connections
In cloud services all kinds of information, whether image, audio or audiovisual content, find their home in the cloud. Accessing this information is a seamless process facilitated by Internet access, allowing users to manage and retrieve their information from almost anywhere.
B. Vendor lock-in
A major challenge in cloud services is the concept of vendor lock-in. This happens when companies encounter obstacles in moving their services from one service provider to another. The various platforms offered by different vendors can make it difficult to switch from one cloud service to another.
C. Limited Control
The cloud infrastructure is fully owned, maintained and controlled by the service provider. Because of this, users of cloud services have limited control over the functional aspects of the services and their implementation in the cloud framework.
D. Security Issues
Despite the strict security measures implemented by cloud service providers, there are inherent risks. Organizations should be careful when entrusting all their data to a third party - a cloud service provider. Sharing data in the cloud carries potential risks of data breach or unauthorized use.
