The current COVID-19 pandemic has driven individuals to work from home, yet they must communicate and collaborate online. As a result, we see cloud computing as playing an important part in meeting the issue of working from home while delivering effectively. During a lockdown, cloud computing technology assists in providing excellent service in the healthcare industry. It provides excellent infrastructure to facilitate digital transformation.
Every country has taken significant steps to halt the spread of the virus. Modern technologies play an important part in the fight against it. Thus, the existing technologies such as Artificial intelligence (AI), cloud computing, Internet of things (IoT), sensor technologies, robotics, and other technologies all contribute significantly to mitigating the consequences. Cloud computing and storage are one step ahead in terms of contribution among these technologies. Cloud services are utilized to store, monitor, forecast, and analyze a massive amount of data. This simplifies the time-consuming work of data processing and costs benefits.
Create strong applications with a diverse array of computing, storage, database, and networking components. Build on the cloud, where cloud solutions are available for every stage of your business.
Top benefits of cloud computing
Cloud computing represents a significant departure from the typical way that organizations think about IT resources. Here are seven typical reasons why businesses are flocking to cloud computing services:
Cost
Cloud computing reduces the capital investment of purchasing hardware and software as well as establishing and operating on-site datacenters—the racks of servers, round-the-clock electricity for power and cooling, and IT specialists to manage the infrastructure. It quickly adds up.
Speed
Since most cloud computing services are self-service and on-demand, even massive quantities of computing resources may be delivered in minutes, generally with only a few mouse clicks, allowing enterprises a lot of flexibility and relieving capacity planning strain.
Performance
The largest cloud computing services are delivered through a global network of secure datacenters that are continually upgraded to the most recent generation of fast and efficient computer gear. This has various advantages over a single corporate data center, including lower network latency for applications and larger economies of scale.
Productivity
On-site datacenters often need a significant amount of “racking and stacking”—hardware installation, software patching, and other time-consuming IT administration tasks. Cloud computing eliminates the need for many of these duties, allowing IT staff to focus their efforts on more critical business objectives.
Global Scale
The capacity to scale elastically is one of the advantages of cloud computing services. That involves delivering the proper amount of IT resources—for example, more or less processing power, storage, and bandwidth—at the right time and from the right geographical location.
Reliability
Although data may be duplicated at numerous redundant sites on the cloud provider’s network, cloud computing enables data backup, disaster recovery, and business continuity easier and less expensive.
Security
Numerous cloud providers provide a comprehensive set of rules, technologies, and controls to assist boost your entire security posture and safeguarding your data, apps, and infrastructure from possible attacks.
Types of Cloud Computing
Not all clouds are created equal, and not every form of cloud computing is appropriate for everyone. Several models, varieties, and services have emerged to provide the best answer for your needs. First, you must choose the sort of cloud deployment or cloud computing architecture that will be used to implement your cloud services. Cloud services may be deployed in three ways: public cloud, private cloud, or hybrid cloud.
Public Cloud
Third-party cloud service providers own and run public clouds, which supply computing resources such as servers and storage through the Internet. Microsoft Azure is an example of a public cloud. All hardware, software, and other supporting infrastructure in a public cloud is owned and controlled by the cloud provider. You use a web browser to access these services and manage your account.
Private Cloud
A private cloud is a set of cloud computing services utilized solely by one company or organization. A private cloud can be physically housed on-site at the company’s data center. Third-party service providers are also used by certain businesses to host their clouds. A private cloud keeps its services and infrastructure on a private network.
Hybrid Cloud
Hybrid clouds are a combination of public and private clouds that are linked by technology that allows data and applications to be exchanged between them. A hybrid cloud provides your organization with better flexibility, and more deployment options, and helps optimize your existing infrastructure, security, and compliance by allowing data and applications to flow between private and public clouds.
Types of cloud services:
IaaS, PaaS, Serverless, and SaaS
The majority of cloud computing services are divided into four categories: infrastructure as a service (IaaS), platform as a service (PaaS), serverless, and software as a service (SaaS). Because they are built on top of one another, they are frequently referred to as the cloud computing “stack.” Knowing what they are and how they vary makes it easier to achieve your company objectives.
Infrastructure as a service (IaaS)
The most fundamental type of cloud computing services. IaaS allows you to rent IT infrastructure—servers and virtual machines (VMs), storage, networks, and operating systems—on a pay-as-you-go basis from a cloud provider.
Platform as a service (PaaS)
Cloud computing services that provide an on-demand environment for designing, testing, delivering, and maintaining software applications are referred to as platforms as a service. PaaS is intended to make it easier for developers to construct web or mobile apps without having to worry about setting up or managing the underlying infrastructure of servers, storage, networks, and databases.
Serverless Computing
Serverless computing, which overlaps with PaaS, focuses on developing app functionality without having to constantly manage the servers and infrastructure necessary to do it. The setup, capacity planning, and server administration are handled by the cloud provider. Serverless architectures are extremely scalable and event-driven, consuming resources only when a specific function or trigger is triggered.
Software as a service (SaaS)
Software as a service (SaaS) is a technique of distributing software programs via the Internet on demand, generally by subscription. Cloud providers host and maintain the software application and supporting infrastructure, as well as any maintenance, such as software upgrades and security patching, via SaaS. Users access the program over the Internet, typically using a web browser on their phone, tablet, or PC.
