Cloud Computing – Cloud Services and Deployment Models

What is Cloud Computing?

Cloud computing refers to on-demand access to IT resources such as data storage, servers, databases, networking and software applications without the direct management of the user. Instead of purchasing, operating and maintaining physical data centers and servers, one can obtain the necessary 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 via the Internet. It lets the user work from anywhere, as they do not need to be in a fixed location to use it.

cloud computing services

A cloud-service model can be selected from the cloud stack, which consists of three cloud computing (and specific business) models that are distinguished by key participants, resources, value created, expense and revenue streams. The 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)

It is a system for software distribution in which the cloud service provider hosts the apps and makes them accessible to customers via 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 most of the engineering work associated with a cloud service. In just a few minutes, you can deploy a MySQL database and start writing data to it. In the SaaS model, businesses are not committed to costly long-term agreements for software support and maintenance, but the vendor receives recurring revenue from the subscription, which is much more valuable than the one-time license fee.

Platform as a Service (PaaS)

Platform as a Service (PaaS) is a service model that provides a virtual platform for developing, deploying and managing the application lifecycle for Internet-based applications. PaaS is a version of SaaS with additional architectural and utility components, and is often used for accelerated development and deployment of mobile and web applications. PaaS caters to the engineering/product development needs of a corporation. PAAS allows the 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 networks, storage, and servers. IT resources are hosted on other servers, and users can connect to them via the Internet. This eliminates the need to place servers in a data center, connect them to a network, or attach storage to them. Flexibility and virtualization are the two most essential benefits of IaaS. IaaS meets the demands of the IT department and eliminates the need for enterprises to make initial investments in their technology infrastructure.

cloud deployment model

The 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 can change, the services to be offered to you, and the infrastructure you control. It is important to select the optimal cloud service deployment model from the available options. This will guarantee that your organization has the required performance, scalability, confidentiality, 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 the infrastructure, including hardware, software, and network capability. The biggest benefits of cloud services include elastic scalability, resource efficiency, and reduced 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 a “cloud burst”, and can be used to scale up or down as needed. Amazon Web Services (AWS), Microsoft Azure, IBM Cloud and Google Cloud are the major public 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 can also decide to host it externally. When it comes to flexibility, Private Cloud offers more options that help organizations meet their unique needs. It is also a sensible solution for mission-critical processes whose needs can change frequently. 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, a hybrid cloud is a combination of two or more clouds (private, communal, or public) or on-premises services that remain independent entities but together to provide the benefits of multiple deployments. are attached. Many enterprises already have hardware they want to continue to use with 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 rest of the applications to the public cloud. A hybrid cloud deployment model is the right way to go for businesses with older applications that contain sensitive data. AppsVolt migrated a legacy desktop healthcare application to a cloud-based healthcare solution using a hybrid deployment model.

community cloud

The community cloud functions in a similar way to the public cloud, with the only difference being that it restricts access to a specified group of users with similar goals. It is a distributed system set up by combining the services of multiple clouds to meet the specific needs of a community, industry or enterprise. Most of the time, it is managed in collaboration with a third party or community organizations.

AppsVolt is an efficient cloud computing solutions provider. Our experience includes converting legacy desktop applications to cloud-based solutions using data analytics solutions in Microsoft Azure and AWS. Please contact us for your cloud migration needs.
