Why Cloud Computing – Cloud computing affects us all. There is an explosion of cloud-based applications and services. Click here to learn the basics of private, public and hybrid cloud.
Cloud computing is defined as the use of data storage, servers, databases, networks and software over the Internet. Since the introduction of cloud computing, the world has seen an explosion of cloud-based applications and services in IT, which is expanding. By 2021, every small and large application we use will be in the cloud, helping us save storage space, costs and time. This article discusses the types of cloud computing and 10 trends in 2021.
Why Cloud Computing
Cloud computing refers to the use of data storage, servers, databases, networks and software over the Internet. The data is stored on the physical servers hosted by the cloud service provider. Computing system resources, especially data storage and computing power, are available on demand, without direct user management in cloud computing.
What Is Cloud Computing ? Definition, Types And Functions
Instead of storing files on a storage device or hard drive, the user stores them in the cloud, making the files accessible from anywhere as long as they have access to the internet. The services hosted in the cloud can be divided into infrastructure-as-a-service (IaaS), platform-as-a-service (PaaS), and software-as-a-service (SaaS). Based on the deployment model, cloud can be classified as public, private and hybrid cloud.
In addition, the cloud can be divided into two different layers, namely front-end and back-end. The layer where users interact is called the front-end layer. This layer allows the user to access data stored in the cloud through cloud computing software.
The back-end layer is the layer that consists of software and hardware, i.e. computers, servers, central servers and databases. This layer is the core of the cloud and is fully responsible for securely storing data. To ensure seamless communication between connected devices via cloud computing, central servers use software called middleware that acts as a bridge between databases and applications.
Cloud computing can be classified by deployment model or service type. Based on the specific deployment model, we can classify cloud as public, private and hybrid cloud. At the same time, based on the cloud model of the service, it can be classified as infrastructure-as-a-service (IaaS), platform-as-a-service (PaaS), and software-as-a-service (SaaS). offers.
What Is Cloud Computing?
In a private cloud, the computing services are delivered over a private IT network for the exclusive use of an organization. Also referred to as an internal, corporate, or corporate cloud, a private cloud is typically managed by internal resources and cannot be accessed by anyone outside the organization. Private cloud computing offers all the benefits of public cloud, such as self-service, scalability and elasticity, with added control, security and customization.
Private clouds provide a high level of security through corporate firewalls and internal hosting to ensure that an organization’s sensitive information cannot be accessed by external providers. The downside of a private cloud is that the organization is responsible for the management and maintenance of all data centers, which requires a lot of resources.
Public cloud refers to computing services provided by third-party providers over the Internet. Like a private cloud, services on a public cloud are available to anyone who wants to use or buy them. These services can be sold for free or on demand, with users paying only for the CPU cycles, storage, or bandwidth they use.
Public clouds allow businesses to save on purchasing, managing, and maintaining on-premises infrastructure because the cloud service provider is responsible for managing the system. They also offer expandable RAM and flexible bandwidth, making it easy for businesses to expand their storage needs.
A Brief History Of Cloud Computing
A hybrid cloud uses a combination of public and private cloud features. With a best of both worlds cloud model, workloads can shift between private and public clouds as compute requirements and pricing change. As demand for computing and processing fluctuates, hybrid cloud allows companies to use on-premises infrastructure in the public cloud to manage revenue streams and ensure that third-party databases cannot access their data.
In the hybrid cloud model, companies only pay for the resources they use on a temporary basis, rather than acquiring and maintaining resources that may not be used for a long time. In short, a hybrid cloud offers the benefits of a public cloud without the security risks.
Based on the service model, cloud can be classified into IaaS (Infrastructure-as-a-Service), PaaS (Platform-as-a-Service) and SaaS (Software-as-a-Service). Let’s look at each of them.
Infrastructure as a Service or IaaS is a form of cloud computing where the service provider is responsible for delivering servers, storage and networking through a virtual interface. With this service, the user does not have to manage the cloud infrastructure, but has control over the storage, the operating system and the deployed applications.
How Cloud Is Making Your Work Faster And Easier
A third-party provider manages hardware, software, servers, storage, and other infrastructure components on behalf of the user. The provider also hosts and backs up the user’s applications.
A Platform as a Service or PaaS is a type of cloud computing that provides a development and deployment environment in which users can develop and run applications without the complexity of building and maintaining the infrastructure. It provides users with the means to develop cloud-based applications. In this type of service, the user purchases the resource from the seller on a pay-as-you-go basis and accesses it over a secure connection.
PaaS does not require users to manage the underlying infrastructure such as the network, servers, operating systems or storage, but gives them control over deployed applications. This frees organizations from the responsibilities of software maintenance, planning, and resource procurement, so they can focus on deploying and managing their applications.
With SaaS or software as a service, users can access the provider’s software on a cloud basis on a subscription basis. With this type of cloud computing, users do not need to install or download applications locally. Instead, the applications reside on a remote cloud network that can be accessed directly through the Internet or an API.

In the SaaS model, the service provider manages all hardware, middleware, application software, and security. SaaS, also known as “hosted software” or “software on demand,” makes it easy for enterprises to streamline their maintenance and support.
The main reason why cloud computing is growing rapidly is that it has several advantages. It saves companies time and resources to set up a complete physical IT infrastructure. Let’s take a look at all the benefits the cloud has to offer:
Cloud expert Lucy Thorpe of Encloud Solutions, speaking about the benefits of cloud computing, says: “Cloud technology is ideal for businesses to grow because it allows you to scale your computing capabilities as you grow – adding more users and adding new ones. unlocking functionality. So, for example, if a company buys a software-in-a-box solution from a cloud service provider, you can start by speeding up the basic accounting processes using the finance element and then move to other parts of the system, such as HR , CRM and project management.
The biggest challenge of cloud computing is the security risks associated with the technology. While cloud service providers assure you of implementing the best security standards and industry certifications, there is always a risk with storing your data in the cloud.
Why Cloud Computing Is Ideal For Small Businesses
Globally, cloud computing is a very mature and growing market. It was valued at $321 billion in 2019 (including all cloud types and service models) and is expected to reach $1025.9 billion within seven years. 2021 is a critical year for cloud computing due to the accelerated pace of adoption in response to the Covid-19 pandemic. This has led to new trends, areas of attention and opportunities.
The public cloud has very few barriers to entry and is very accessible to small businesses, startups and independent professionals. As a result, the public cloud segment is expected to grow by 18.4% by 2021, to an estimate of $304.9 billion by Gartner.
This is the fastest growing software-as-a-service (SaaS) and platform-as-a-service (PaaS) account with the largest market share. The demand for distributed teams and digital collaboration has increased the demand for cloud computing and cloud-based applications, extending to IT operations through cloud-based cybersecurity, network management and service delivery.
The year 2020 and 2021 were marked by several notable cloud outages, affecting some of the largest providers in the world. In the year March 2020, some Azure North American customers experienced a six-hour service interruption due to a cooling system failure. Google’s cloud services have gone down several times in the past year, and in April, Microsoft had another outage that affected both Microsoft 365 and Azure. By 2021, companies will invest in cloud agnostic platforms with multi-cloud and hybrid cloud strategies to ensure maximum IT resilience.
Benefits Of Cloud Computing For Your Business
Regardless of the parent hosting environment (on-premises servers, cloud, or hybrid), containers provide an independent virtual environment to build and run applications. In short, it enables companies to build small and isolated clouds in their own infrastructure to enhance their development capabilities.
