What is cloud computing?

Cloud computing refers to manipulating, configuring, and accessing the applications online. It offers online data storage, infrastructure, and application. It provides us a means by which we can access applications as utilities over the Internet. cloud computing allows us to create, configure and customize applications online with cloud computing, users can access database resources with the Internet from anywhere for as long as they need. Without worrying about any maintenance or management of actual resources. cloud infrastructure involves the hardware and software components required for the proper implementation of a cloud computing model. These services are divided into three main categories or types of cloud computing: infrastructure as a service, platform as a service, and software as a service. It also refers to the technology that makes the cloud work. This includes some form of virtualized IT infrastructure- servers, operating system software, networking, and other infrastructure that’s abstracted, using special software, so that it can be pooled and divided irrespective of physical hardware boundaries.

How does cloud computing work?

Cloud computing works to enable client devices and access data so these cloud applications go through the internet from the remote physical servers, computers, and databases. The internet network connection links the front end, which includes the accessing client device, browser, network, and cloud software applications, with the back end, which consists of databases, servers, and computers. communications between the front and back ends are managed by a central server. The server of central data relies on protocols to facilitate the exchange of data. There is a dedicated server for each individual application or workload.

Cloud computing relies heavily on virtualization and automation technologies. To comprehend how a cloud system works, it is easier to categorize them into 2 sections: the front end and the back end. They’re linked to one another via a network. cloud storage users can also edit documents or with other users as well, making it easier to work away from the office. history of cloud computing

How safe is the cloud

Every day, millions of new records are generated and stored digitally in the cloud. Special attention should apply to security standards offered by the cloud provider. Including measures to secure transmission and storage of data, as well as the physical security of the cloud provider data center to control the access rights of your own employees. With the word tired approach to cloud security, we protect the most important data in which we monitor our application systems and processes continuously and optimized so that they meet the increasing demands and safety requirements.

Types of Cloud Computing Services

1. Iaas- Iaas providers, such as amazon web services, supply a virtual server instance and storage, as well as application programming interfaces that let users migrate workloads to a virtual machine. The Iaas cloud model is closest to a remote data center for business users.

2- Paas- Cloud providers host development tools on their infrastructures. Users access these tools over the internet using APIs, web portals, or gateway software. PaaS is used for general software development, and many PaaS providers host the software after it is developed. Common PaaS products include salesforce’s lightning platform, AWS Elastic Beanstalk, and google app engine.

3- SaaS- Saas is a distribution model that delivers software applications over the internet, these applications are called web services. In the Saas applications and services from any location using a computer or mobile device that has internet access. one common example of a SaaS model, is users gain access to application software and databases. An example of Saas is Microsoft 365 for productivity and email services.

Who uses the cloud?

The cloud has become so integral to our everyday lives that most people use it without even realizing it. For so many people, life without the cloud would be radically different. There would be no Facebook, no Gmail, and no Twitter. The cloud has transformed the business landscape. Today, millions of organizations around the world rely on cloud services for everything from document creation and backup to social CRM and accounts. Companies with over 25,000 employees use an average of 545 cloud apps or services. Over half of all Internet users rally on cloud-based email services like Gmail and Yahoo. Just mail to send and receive their messages.

History of Cloud Computing

Cloud Computing was invented in the early 1960s by J.C.R Licklider (Joseph Carl Robnett Licklider), an American Psychologist and Computer Scientist. During his network research work on ARPANet (Advanced Research Project Agency Network), trying to connect people and data all around the world, gave an introduction to the Cloud Computing technique which we all know today. Born on March 11^th, 1915 in St. Louis, Missouri, US, J.C.R Licklider pursued his initial studies. In 1961, John MacCarthy delivered his speech at MIT that “computing can be sold as a utility, like water and electricity. They thought the technology they are using was efficient enough for them. So this is implemented by salesforce.com in 1999. This company started delivering an enterprise application over the internet and this way the boom of cloud computing was started. The pandemic accelerated business adoption of cloud services as the organization turned to online services and infrastructure to accommodate remote employees and customer demand for online meetings, events, and commerce.

Advantages of Cloud computing

1. Self-service provisioning- End users can spin up compute resources for almost any type of workload on-demand. An end-user can provision computing capabilities, such as server time and network storage, eliminating the traditional need for IT administrators to provision and manage to compute resources.

2- Elasticity- Companies can freely scale up as computing needs increase and scale down again as demands decrease. This is to eliminate the need for massive investments in local infrastructure and which might or might not remain active.

3- Pay per use- Compute resources are measured at a granular level, enabling users to pay only for the resources and workloads they use.

4- Workload resilience- CSPs often implement redundant resources to ensure resilient storage and to keep users’ important workloads running often across multiple global regions.

5- Migration flexibility- Organizations can move certain workloads to or from the cloud– or to different cloud platforms- as desired or automatically for better cost savings or to use services as they emerge.

6-Migration flexibility- Organizations can move certain workloads to or from the cloud — or to different cloud platforms as desired or automatically for better cost savings or use new services as they emerge. Advantages of cloud computing

Disadvantages of Cloud Computing

1-Dependency- Cloud computing is the user’s dependency on the provider. Dependency on the availability and quality of communication.

2-Risk- Cloud computing services mean taking services from remote servers. The risk of technical damages so taking services in remote servers.

3-Requires a constant internet connection- The most obvious disadvantage is that this computing completely relies on network connections. This is where a cloud computing service can become expensive.

4- Security- Security and privacy are the biggest concerns about cloud computing. Their dependence on remote cloud-based infrastructure means. Taking on the risk of outsourcing everything.

5-Migration issue- The migration problem is also a big concern about cloud computing. The challenge of cloud migration we most often that it is lacking a clear strategy determined by business objectives. Cloud sprawl is caused by not having a clear understanding of the full scope of cloud environments.

6-Limited control and flexibility- The cloud infrastructure is entirely owned, Managed, and monitored by the service provider. It transfers minimal Control over to the customer. Customers retain control of their applications, data, and services, but may not have the same level of control over their backend infrastructure.

Conclusion

Cloud computing is the fastest-growing part of network-based computing. It provides tremendous benefits to customers of all sizes, simple users, developers, enterprises, and all types of organizations. It offers real alternatives to IT departments for improved flexibility and trimming down the cost markets are developing for the delivery of software applications, reforms, and infrastructure as a service to other departments or the cloud. These services are readily accessible on a pay-per-use basis and offer great alternatives to businesses that need the flexibility to rent infrastructure on a temporary basis or to reduce Capital costs. Computing technology is undergoing important transitions and changes are creating serious data security, privacy, and management challenges. Our application on Android is an attempt to accomplish sharing of files over the cloud. It is rapidly emerging as a viable alternative to traditional approaches. Agencies’ costs are being significantly reduced along with personal time spent on computing issues. Storage availability increases, higher automation eliminates worries about keeping applications up to date, and flexibility and mobility.
