Introduction to Cloud Computing: Concepts, Models, Characteristics & Benefits

For example, healthcare providers and government agencies often implement community clouds in their operations. The cloud refers to software tools and services that operate with the use of the Internet or web browser. This is in contrast to legacy systems that only run locally on a computer. Therefore, cloud computing is when services, such as data storage, networking, and servers, are delivered through the Internet. With cloud computing, users can store files on a remote database, rather than on a hard drive or storage tool.

It can improve business, but every step in the project raises security issues that must be addressed to prevent serious vulnerabilities. They have a significant physical footprint, requiring allocations of space, hardware, and environmental controls. These assets have to be refreshed periodically, resulting in additional capital expenditures.

Some applications run better on one type of server and configuration, so it’s up to the customer to know which PaaS service is best to host their application. The Institute also defines five fundamental characteristics for establishing a cloud solution architecture of cloud computing. In the world we live in today, the majority of companies are transforming their businesses using data.

” Well, a hybrid cloud refers to the pairing of both private and public clouds. As previously mentioned, it relies on a private datacenter (third-party hosted or on-premises), typically used to host sensitive data, while also leveraging the computing power/resources of a public cloud. A multi-cloud model can include the use of a hybrid cloud, but it relies on more than a single public cloud. For example, a company may choose to store sensitive data in their on-premise datacenter, leverage one public cloud provider for the “IaaS” services and a second public cloud provider for their “SaaS” services. Cloud computing is the on-demand delivery of different computing services over the internet, including databases, software, servers, and analytics.

Cloud Computing Models

GPS tracking is a location-based service that uses satellite navigation to track the location of assets and people. It is often used by businesses to track the location of vehicles, fleets, and other equipment. GPS tracking can also be used for personal tracking applications, such as monitoring children or elderly family members. One of the most exciting applications of cloud computing is in the area of antivirus.

We can distinguish between thin clients and rich clients (or thick/fat clients). A thin client is heavily dependent on the computation power and functionality of the server. A rich client cloud team is a computer that provides itself rich functionality independent of the central server. By now you are probably thinking, “So what is the difference between hybrid and multi-cloud?

Infrastructure as a Service (IaaS)

The vendors provide their clients with a platform to deploy their applications without worrying about the storage and infrastructure. It provides a virtual runtime environment to develop and test applications. Although, these applications can only be written in languages the vendor’s platform allows.

Having now outlined the various risks faced when using clouds, we can now take a look at the methods industry has developed to deal with these issues. In this section we will focus on the methods used to ensure all the various forms of data security, and also take a brief look at the strategies employed to solve the other secondary issues. A. On-demand self-service cloud solutions and services A Cloud Service Customer can use an online interface to allocate computing resources like additional computers or network bandwidth without human interaction with their Cloud Service Provider . Colocation/Remote Services – In this type of service, the servers are located across multiple locations worldwide, and remote devices can access the server services.

Cloud Computing Models

Cloud-based antivirus is also more effective at detecting and removing viruses because the cloud-based system can analyze a more significant number of samples and can quickly identify new threats. Integrating сloud solutions into your website and organizational practices is the tried-and-proven method of automating your interactions with clients and team members, which leads to significant efficiency increases. OneDrive, Google Drive, Dropbox, and Box offer free space to create cloud backup copies, both manually and automatically. You may access the SaaS software from a laptop, desktop, tablet, or smartphone using a web browser such as Google Chrome.

Software-as-a-Service, or SaaS

Private cloud installations are in part motivated by users’ desire to retain control over the infrastructure and avoid losing control of information security. The cloud deployment model identifies the specific type of cloud environment based on ownership, scale, and access, as well as the cloud’s nature and purpose. The location of the servers you’re utilizing and who controls them are defined by a cloud deployment model.

Cloud Computing Models

Multiple users or staff can collaborate remotely on a project using IaaS. The scalability of the infrastructure is determined by the storage and processing requirements. Communication is crucial for preparing your company for the cloud, so keep stakeholders informed on a regular basis and ensure the IT sector is part of the decision-making process.

Which of the following subject area deals with pay-as-you-go usage model?

However, they should be aware that the server space is owned and managed by the provider. The third-party has full responsibility for data security and availability, which is why it’s important to choose a trustworthy cloud provider. The provider should encrypt the data both when it’s being transferred to the cloud and during the storage itself.

  • A Private Cloud is appropriate for delicate information, where the client is subject to a specific level of security.

Due to the use of the internet, confidential information such as employee data and user data can be easily available to third-party organisations and people in Cloud Computing. Capabilities can be elastically provisioned and released, in some cases automatically, to scale rapidly outward and inward commensurate with demand. To the consumer, the capabilities available for provisioning often appear unlimited and can be appropriated in any quantity at any time. Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, tablets, laptops, and workstations). Cloud sandbox—A live, isolated computer environment in which a program, code or file can run without affecting the application in which it runs.

Data Analytics and Solution Consulting

Availability improves with the use of multiple redundant sites, which makes well-designed cloud computing suitable for business continuity and disaster recovery. Productivity may be increased when multiple users can work on the same data simultaneously, rather than waiting for it to be saved and emailed. Time may be saved as information does not need to be re-entered when fields are matched, nor do users need to install application software upgrades to their computer. Performance is monitored by IT experts from the service provider, and consistent and loosely coupled architectures are constructed using web services as the system interface.

In PaaS, users are billed only for the platforms that they use for the time when the services were used. There is no need to pay for excessive functionality, like in desktop solutions. Over the years, business owners received tangible proof of cloud multiple benefits — and the statistics serve excellent evidence. Let’s see what these advantages that managed to attract millions of users all over the world are and how they apply to your business.

Cloud Computing Models

Software as a Service In this model, the vendor provides customers with software applications using their cloud infrastructure and cloud platforms. These end user applications are typically accessed by users via web browser, as such there is no need to install or maintain additional software. The vendor is mainly responsible for ensuring all forms of security in this service.

1 Cloud Service Models

Popular apps and services for service management, project management, HR management, etc., are all available online. Some popular cloud-based programs include Vimeo, Datadog, Slack, Zoom, Dropbox, Hiroku, etc. Therefore, if you use anything that someone else can check out simultaneously at the same time, you are using a cloud service. A community cloud is a shared environment in which several companies, or even individuals, gain the benefits of a public cloud by using private cloud-like controls and security. Poly cloud refers to the use of multiple public clouds for the purpose of leveraging specific services that each provider offers.

Cloud model relies on

The IT departments in companies are now actively hiring cloud architects, cloud software engineers, cloud consultants, cloud specialists, and cloud engineers. More jobs will continue to prosper as long as interactions like these are made with customers. Young individuals keen to learn about technology and who are willing to contribute can easily make good money by working in the cloud domain. Cloud computing is nothing but a delivery model of computing services that are done over the internet. It unlocks various features, such as real-time deployment, development, and delivery of solutions and services. They are engineered to allow people to use and store data on both platforms seamlessly.

2 Methods to ensure Data security

Internet-based cloud computing delivers data and shared computing resources on demand to computers and other devices. It is a design that makes it possible for anybody, anywhere, to have easy, anytime access to adjustable computer resources through the network (e.g., networks, servers, storage, applications, and services). With little administration work or service provider contact, these resources may be quickly supplied and released. Like a public utility, cloud computing depends on sharing resources to create coherence and economies of scale. Cloud services are considered “public” when they are delivered over the public Internet, and they may be offered as a paid subscription, or free of charge. Architecturally, there are few differences between public- and private-cloud services, but security concerns increase substantially when services are shared by multiple customers.
