Types, Benefits and Use Cases of Cloud Computing
Cloud computing allows companies and individuals to rent instead of purchasing their IT. Today, companies choose to access their computing power over the internet or the cloud and pay for it as they use it rather than making significant investments in databases, software, and hardware. The current cloud service examples include servers, storage, databases, networking, software, analytics, and business intelligence. The speed, scalability, and flexibility that cloud computing offers enables firms to create, innovate, and maintain commercial IT solutions.
Cloud computing technology offers considerably more than the sum of its components. It facilitates the use of cloud-native technology, encourages more effective working practices, and fosters the development of machine learning (ML) and artificial intelligence (AI) skills (AI). Cloud computing has boosted innovation and competition in the business industry via cost reductions, increased flexibility, elasticity, and efficient resource use.
Uses of Cloud Computing
Storing files in the cloud is convenient, as they can be easily accessed and edited. Files are accessible from any device, anywhere; all that is needed is an internet connection. Cloud storage comes in various forms, including block, file, and object storage. Each is suitable for a distinct use case. Using cloud computing storage services, companies gain secure accessibility and scalability to add or reduce storage based on their demands and budget. Cloud computing storage is not only very economical but also quite safe.
Infrastructure-as-a-Service (IaaS) and Platform-as-a-Service (PaaS)
IaaS (Infrastructure as a Service) offers users pay-as-you-go access to basic computing, network, and storage capabilities on demand through the internet. Companies can cut expenses by using pay-per-use cloud infrastructure instead of purchasing, administering, and managing their own IT system. Moreover, the cloud is conveniently accessible. IaaS is included with most of the main cloud service providers' cloud computing services, including Amazon Web Services (AWS), Google Cloud, IBM Cloud, and Microsoft Azure.
Platform-as-a-Service (PaaS) gives users access to a full cloud platform, including hardware, software, and infrastructure, so they can build, run, and manage applications without having to worry about the expense, complexity, or rigidness of establishing and managing that platform on-premises. Businesses can use PaaS to accelerate development on a ready-to-use platform and deliver applications with a dependable and affordable pricing structure.
Although software-as-a-Service (SaaS) is similar to IaaS and PaaS, it has significantly revolutionized the way businesses access software. Instead of requiring IT personnel to purchase and install software on each system, SaaS enables online access to applications via a subscription.
SaaS providers enable access to software whenever and wherever there is an Internet connection. These solutions have enabled more sophisticated tools and capabilities, including automation, improved processes, and real-time communication across several locations.
The Hybrid Cloud and the Multi-Cloud
A hybrid cloud is a computer environment that combines on-premises private cloud services a business provides with external public cloud services to provide a unified, adaptable infrastructure for executing mission-critical workloads and applications. It is simpler to choose the best cloud for each application or task and then shift the workloads easily between the two clouds when conditions change, thanks to this special combination of public and private cloud resources.
Multi-cloud, on the other hand, enables businesses to utilize two or more clouds from several providers. Any combination of IaaS, PaaS, or SaaS resources can be used in this kind of cloud computing. Workloads can be executed in many cloud environments using Multi cloud to meet specific requirements. This implies that businesses can avoid vendor lock-in.

• Private Clouds
• Hybrid Clouds
• Multi Clouds
• High-Performance Computing Clouds
Advantages of Cloud Computing
The agility and speed of software development have changed because of the quick creation of new cloud computing instances. Developers may quickly test new concepts and create application architecture without being constrained by on-site hardware restrictions or drawn-out procurement procedures.
Automatic Software Upgrades and Integration
Cloud computing has made it easier to develop, upgrade and integrate software. New software versions can be readily tested and deployed in the cloud environment, continuously allowing for increased product innovation velocity and improved features' integration.
Companies can save money on acquiring and maintaining equipment by using cloud infrastructure. This significantly decreases CAPEX and Total Cost of Ownership (TCO). Companies do not need big IT teams to manage their cloud data center operations as they can rely on their cloud provider. Companies also don't have to spend time or money resolving possible downtime issues.
The cloud has several advanced security mechanisms to ensure data is safely stored and managed. Granular permissions and access control limit access to sensitive data to only the personnel who need it, lowering the attack surface for hostile actors.
Baseline safeguards, such as authentication, access control, and encryption, are implemented by cloud storage providers for their platforms and the data they handle. Most businesses enhance these safeguards with additional security measures of their own to strengthen cloud data protection and restrict access to sensitive information in the cloud.
