Cloud Computing – Cloud Services and Deployment Models

What is Cloud Computing?

Cloud Computing refers to the on-demand accessibility of IT resources such as data storage, servers, databases, networking, and software applications without the user’s direct management. Rather than purchasing, operating, and maintaining physical data centers and servers, one may acquire as-needed computing power, storage, and databases from a cloud service provider.

Cloud service providers enable customers to store files and apps on remote servers and then access the information through the Internet. This lets the user work from anywhere, since they don’t have to be in a certain place to use it.

Cloud Computing Services

A Cloud-Service model may be selected from the cloud stack, which consists of three cloud computing (and distinct business) models that are distinguished by key participants, resources, value created, expenses, and revenue streams. Three different service models are Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS).

Software as a Service (SaaS)

This is a system for software distribution in which a Cloud Service Provider hosts apps and makes them accessible to subscribers through the internet. The cloud service provider handles the cloud architecture, scalability of the underlying hardware, operating system, and database management system version. SaaS has the advantage of offloading the majority of the engineering work associated with a cloud service. In a matter of minutes, you can deploy a MySQL database and begin writing data to it. In a SaaS model, businesses are not committed to costly long-term agreements for software support and maintenance, but the vendor receives recurring revenue from subscriptions, which is far more valuable than one-time license fees.

Platform as a Service (PaaS)

Platform as a Service (PaaS) is a service model that offers a virtual platform for developing, deploying, and managing the application lifecycle for internet-based applications. PaaS is a version of SaaS with extra architectural and utility components, and is often used for the quick development and deployment of mobile and web applications. PaaS caters to the engineering/product development requirements of a corporation. PAAS allows outsourcing of both physical infrastructure and software environments, including databases, integration layers, and runtimes.

Infrastructure as a Service (IaaS)

Infrastructure As A Service (IAAS) refers to the leasing and use of a third-party provider’s physical IT infrastructure, such as network, storage, and servers. The IT resources are hosted on other servers, and users can connect to them through the internet. This eliminates the need to place servers in the data center, connect them to the network, or attach storage to them. Flexibility and virtualization are the two most essential benefits of IaaS. IaaS satisfies the demands of the IT department and eliminates the need for enterprises to make initial investments in their technological infrastructure.

Cloud Deployment Model

A Cloud Deployment Model specifies the cloud services you are using and the management responsibility model. It specifies your cloud architecture, the scalability of your computing resources, what you may alter, the services offered to you, and how much of the infrastructure you control. It is vital to select the optimal cloud service deployment model among the available options. This would guarantee that your organization has the required performance, scalability, privacy, security, compliance, and cost-effectiveness. There are four major Cloud Deployment Models.

Public Cloud

Public Cloud is where computer services are offered and accessed over a publicly accessible network. In this deployment approach, a third-party service provider owns and maintains all infrastructure, including hardware, software, and network capacity. The greatest benefits of cloud services include elastic scalability, resource efficiency, and a reduction in initial capital expenditure. One only has to pay for the resources they use, and they can add or remove resources as needed. This is called “cloud bursting,” and it can be used to scale up or down as needed. Amazon Web Services (AWS), Microsoft Azure, IBM Cloud, and Google Cloud are the major Pubic Cloud Service providers.

Private Cloud

Private Cloud is an environment allocated to a particular firm or organization. Private Clouds combine self-service and scalability with the security and control of an on-premises IT infrastructure. It will be managed by your IT team and linked to your data center. You may also decide to host it externally. When it comes to flexibility, the Private Cloud provides more alternatives that help organizations fulfil their unique needs. It is also a sensible solution for mission-critical procedures whose needs may change often. Red Hat OpenStack, Rackspace, IBM Bluemix Private Cloud, Microsoft Azure Stack, and VMware Private Cloud are examples of well-known private cloud providers.

Hybrid Cloud

As the name suggests, Hybrid Cloud is the combination of two or more clouds (private, communal, or public) or on-premise services that remain independent entities but are connected together to provide the advantages of numerous deployment types. Many enterprises already possess hardware that they wish to continue utilizing alongside cloud-based services, making the Hybrid Cloud model the most popular option. In this deployment model, the organization can choose to run some applications on-premises while deploying the remaining applications to the Public Cloud. A Hybrid Cloud deployment model is the right way to go for businesses with legacy applications that contain sensitive data. Appsvolt migrated a legacy desktop healthcare application to a cloud-based healthcare solution using Hybrid Deployment Model.

Community Cloud

The community Cloud functions in a similar manner to Public Cloud, the sole distinction is that it restricts access to a specified group of users that have similar goals. It is a distributed system established by combining the services of many clouds to meet the particular requirements of a community, industry, or enterprise. The majority of the time, it is managed by a third party or a collaboration of community organizations.
