Cloud computing

Types of cloud computing

Cloud computing refers to storing and accessing data and programs over the Internet instead of a computer's hard drive. Basically, there are three types of cloud computing: public, private, and hybrid.

• Public cloud: A public cloud is a cloud computing system from which services such as servers and storage are delivered over the Internet by a third-party provider. Resources such as hardware and storage are shared among multiple organizations, also known as tenants. Public clouds are beneficial because they offer great scalability and cost-effectiveness, and they are ideal for workloads with fluctuating needs or quick development timelines.
• Private cloud: Private clouds are cloud computing environments that only a single business or organization can use. A private cloud offers greater flexibility and allows businesses to customize their cloud computing to meet specific needs. Because it is only available to one organization, private clouds are more secure and compliant.
• Hybrid cloud: Hybrid clouds combine public and private clouds, allowing data and applications to be shared between them. By using hybrid cloud systems, organizations can keep their sensitive data secure in private clouds while taking advantage the public cloud's expansive resources.

Features of cloud computing

The functions of cloud computing differ among the deployment types and service models (IaaS, PaaS, SaaS). Here are some of the common features of cloud computing:

• Automation: Manual intervention is needed to do tasks in a cloud environment because sending compute resources to consumers requires speed and scale. Dynamic provisioning of resources and self-service provisioning are examples of automated functions. Resources should automatically provision and deprive themselves based on predetermined conditions.
• On-Demand Self-Service: Cloud services enable users to provision resources without needing cloud providers' human contact.
• Broad Network Access: Accessing cloud services from any location using the internet results in broad network access. cloud computing services are accessible via various devices and platforms, including smartphones, tablets, and PCs.
• Resource pooling: By pooling resources across multiple customers, cloud service providers can use their resources more effectively. Resources from a cloud service provider are pooled together to serv a large number of customers ccidentally or concurrently, which is known asmultitenancy, customers are then assigned and accessed through software -based tools with on-demand technical configuration level that souce these resources are dynamically assigned according to compution, storage and network resources metered at such granularity that they are even determinable at the level of individual customers
• Scalability: Cloud systems must be elastic to quickly and efficiently accommodate changes in demand for computing, storage, and system software. Systems should be able to scale both horizontally and vertically.
• Reliability: Cloud computing systems must provide timely, credible information about the state of systems, resources, and services.
• Security: A mature cloud computing environment and a security-conscious corporate culture Cloud security is frequently regarded as a shared responsibility.
• Mobility: Mobility implies that one may, at any time and from any location, access the cloud, allowing the workforce to work from wherever this may be and not just from the office. Mobility is made feasible by cloud computing, which allows access via the internet through any device, obtaining data and applications even if those physically stored in the office are not available.

Cloud computing scenarios

Cloud computing has multiple use cases. Here are some of the prominent cloud computing scenarios that showcase the versatility of clouds in delivering solutions to various industries.

• Cloud-based or Virtual Learning Environment (VLE)

  The healthcare or educational industry often uses cloud-based computing to promote Learning (VLE) environments that facilitate Learning regardless of time, user, or geographic constraints. Learners, educators, and administrators can standardize Learning tools and resources through a cloud-hosted learning management system or education platform.

• Data storage and backup systems

  Universities use cloud computing solutions to simplify coordinating and responding to medical and academic emergencies. Schools can leverage cloud services such as inter-institutional data storage and transfer systems to ensure continuity of teaching, Learning, and research. Academics can quickly mobilize evidence, expertise, and research findings through knowledge platforms, cloud-based information systems, social media, and other communications technologies.

• Imaging and cloud radiology

  Cloud radiology is a branch of tele-radiology. It involves storing, processing, and distributing medical images in the cloud. Healthcare organizations typically deploy picture archiving communication systems (PACS) integrated with web-based radiology reporting solutions to fulfill their cloud radiology needs. These solutions enable healthcare providers to refer patients for remote consultations within a few hours, improving access to care.

  Imaging plays a crucial role in diagnosing and screening asymptomatic patients for multiple diseases. Cloud computing technologies can provide affordable radiology and imaging solutions to diverse departments within the stipulated time frames. Clinical decision-making and patient management can be expedited through cloud imaging machinery.

How to Choose Cloud Computing

When selecting a cloud computing platform, businesses must find a partner that meets their unique needs and objectives. To do this, numerous important aspects must be considered carefully, including scalability, the kinds of services offered, security measures, and pricing models.

• Cloud computing Platform: The platform where the service provider runs its cloud infrastructure should be carefully considered and evaluated. Different platforms may offer better performance in certain geographical areas or for particular workloads. It is important to select a partner whose platform offers reliable, high-performance services tailored to specific business requirements.
• Deployment model: When selecting a cloud computing partner, businesses should carefully define the objectives they hope to achieve through the cloud. Public clouds are cost-effective for most companies, while hybrid and multi-cloud models may be more suitable if they need greater control over sensitive data or compliance obligations.
• Scalability: Scalability refers to a provider's capability to expand resources quickly in response to changing demands. Businesses must choose partners whose services can scale up or down easily as their needs evolve without incurring unnecessary costs or downtime.
• Types of services offered: Different service providers may have different types of cloud computing services, including IaaS, PaaS, SaaS, and serverless computing options. Therefore, selecting a partner whose offerings align with specific business requirements is essential.
• Security measures: To protect sensitive data stored in the cloud, It is vital to consider security strongly partnered with cloud computing service providers. Be sure they comply with industry standards and regulations regarding data protection, privacy, encryption, and access controls.
• Pricing models: Businesses should carefully assess the pricing structures associated with each potential partner to ensure transparent costs that suit budgets while offering maximum value for money. Evaluate whether pricing models are based on usage (pay-as-you-go), reserved instances, or subscription-based .
