As the world is going towards digitalization, cloud computing is gaining more and more popularity in the world of business. We all know that from traditional on-premise services, the business world is moving towards cloud-based services.
But do we know what cloud computing means, types of cloud computing and what and all the benefits we can get from cloud services? Choosing cloud computing can be a unique decision. Before choosing a cloud service, let’s read A to Z about this service.
What is the Cloud Computing Definition?
Cloud computing can be defined as the use of hosted services such as databases, servers, data storage, networking, and all the software over the internet.
In simple terms, it is a practice of using a network of remote servers hosted on the internet to store and manage the data rather than hosting it on the local server or a personal computer. Grids and clusters are the foundations for cloud computing.
Instead of storing files on a hard drive or any storage device, user can store their data on cloud storage. Once you save the data on cloud storage, you can access the data from anywhere, anytime, as long as you have access to the web.
there are two different layers of Cloud computing:
» Front-end
» And Back-end
The front-end layer is the layer from which the user can interact. Users can access the data which is stored in the cloud through the cloud computing software.
3 Models of Cloud Services
Are you thinking of moving to the cloud services, but need clarification about what and all options you have with you?
Well! There are 3 models of cloud computing:
» Infrastructure as a Service (IaaS)
» Platform as a Service (PaaS)
» Software as a Service (SaaS)
1. Infrastructure as a Service (IaaS)
Companies that don’t want to maintain their own on-premises data centers use infrastructure as a service. It is a form of cloud computing that provides virtualized or we can say, digitalized computing resources on the internet. Cloud computing is changing the world of Small business now these days
The cloud provided in the IaaS model manages IT infrastructures such as storage, server, and networking resources, and delivers them to subscriber organizations via machines that can be virtually accessed through the internet.
IaaS provider provides the following services:
1. Compute: It includes virtual central processing units and virtual main memories for the virtual machines that are provisioned to the end-users.
2. Storage: The IaaS providers provide back-end storage for storing files.
3. Network: Network as a Service (NaaS) provides networking components such as routers, switches, and bridges for virtual machines.
4. Load Balancers: They provide load-balancing capability at the infrastructure layer.
Advantages of Infrastructure as a Service Cloud Service:
» You pay for what you actually use. The charges are computed via usage-based metrics.
» IaaS is a monthly operational expense and because of this, it reduces capital expenditures.
» It has access to a state-of-the-art data center, hardware and hardware and operating systems and hence it is future-proof.
» It enables instant recovery from outages.
» It can be accessed via a simple internet connection.
Disadvantages of Infrastructure as a Service Cloud Service:
» There is a lack of support i.e., live help is sometimes hard to come by.
» Even the largest service providers experience downtime and depend on managing availability.
» Transferring or moving from one IaaS provider to another can be difficult.
» Peak usage may be more than expected and lead to unexpected costs.
» Service level agreements (SLAs) can be difficult to understand.
Examples of Infrastructure as a Service:
The popular IaaS providers include Microsoft Azure, Amazon Web Services, Rackspace, and Google Compute Engine.
» Microsoft Azure is a cloud computing service developed by Microsoft for building, testing, and deploying applications and services. The data is managed by Microsoft-managed data centers.
» Amazon Web Services is a secure cloud computing platform that offers computing power, database storage, content management, and other functionality to help businesses scale and grow.
» Rackspace is a managed cloud computing company that makes IaaS easy to manage private and public cloud deployments.

2. Platform as a Service (PaaS)
It is a cloud computing model where a third-party provider delivers hardware and software tools to users. Usually, these tools are used for application development.
It provides a runtime environment where programmers can easily create, test, run, and deploy web applications over the internet. You can purchase them and pay on per per-user basis and access them using the internet connection.
It includes various infrastructure and platforms to support the web application life cycle.
PaaS provider provides the following services:
1. Programming Language: The provider provides various programming languages for the developers to develop web applications. Java, PHP, Ruby, Perl, and Go are some of the popular programming languages provided by PaaS providers.
2. Application Frameworks: The providers provide application frameworks to easily understand the development of the application. Node.js, Drupal, Joomla, WordPress, Spring, Playl, etc. are some of the popular application frameworks.
3. Database: PaaS providers provide various databases such as MongoDB, PostgreSQL, etc. to communicate with the applications.
4. Other tools: Other tools that are used for developing, testing, and deploying the applications are also provided by the PaaS providers.
Advantages of Platform as a Service Cloud Service:
» It allows developers to focus on development and innovation without worrying about infrastructure management.
» A developer only requires a PC with an internet connection to start developing applications. There is no need to invest in hardware and software and hence it lowers the risk.
» You can find defined business functionality to avoid developing the application from scratch and you can directly start with the project only.
» These vendors provide online communities where developers can get innovative ideas, share their experiences, and get advice from other developers.
» Application once deployed can scale hundreds of users to thousands of users without any charges.
Disadvantages of Platform as a Service Cloud Service:
» According to the platform provided by the PaaS vendors, the developer needs to write the application, so that migration of an application to another PaaS vendor will be an issue.
» If the data is not located within the walls of the company, there are risks in terms of privacy of the data.
» There might be chances that some applications are on a local server and some are in the cloud. So it will be complex if we use the data that is in the cloud with the local data.
Examples of Platform as a Service:
Here is a table that shows some of the best PaaS providers and services offered by them:
3. Software as a Service
It hosts the applications by making them available to the users by using the internet. With Saas, a business need not have to install or set up any software for its existing IT infrastructures. It is also known as “on-demand software”.
The software as a service provider will host the application and the data related by using its own servers, database, networking, and computing resources.
The application will be accessible to any device that is connected to network connections and is typically accessed via web browsers.
SaaS provider provides the following services:
» Business Services: The SaaS providers provide various business services, especially to start-up businesses. It includes ERP (Enterprise Resource Planning), CRM (Customer Relationship Management), billing, and sales.
» Documentation: SaaS document management is an application software that is offered by third-party SaaS providers to create, manage, and track digital documents.
For example, Slack, Zoho Forms, etc.
» Social Platforms: In today’s world, everyone is highly active on social media platforms like Facebook, Instagram, etc. It is no used by the general public and hence social networking service providers use SaaS for their convenience and handle the data of the general users.
» Mail Services: To handle a numerous number of users and e-mail services, many email providers use SaaS for their service.
Advantages of Software as a Service Cloud Service:
» SaaS is easy to buy and it is based on a monthly fee or annual fee subscription. It allows businesses to access functionality related to the business.
» It offers a one-to-many model in which a single instance of the application can be shared by multiple users.
» You can host the software remotely so that businesses do not need to invest in any additional hardware.
» The services can be accessed from multiple devices such as desktops, laptops, tablets, and phones.
» It is easy to integrate with other software or services through standard APIs.
Disadvantages of Software as a Service Cloud Service:
» The data stored is stored in the cloud, so security can be an issue for some users.
» If you don’t have a proper internet connection, you can’t use most of the SaaS applications.
» Switching SaaS vendors is a difficult and slow process. Transferring large data files over the internet is a tough task.
Examples of Software as a Service:
