Introduction

Cloud Computing Services – You have a variety of eating alternatives when you’re hungry. You may go to the market and buy food for yourself, order food for delivery, cook meals at home, or go to a restaurant.

Currently, cooking at home is an on-premise approach where all the labor must be done using the available resources.

It is an Asset as a Service model where you purchase your dinner at the market; you are then in charge of heating it at home, eating it, and doing the dishes.

You are using a Platform as a Service model when you order meals delivered to your house since you depend on the vendor to do the essential activities involved in cooking. While you furnish dishes, the seller supplies the prepared food.

You use a Software as a Service paradigm when you eat out since you don’t have to prepare the meal. You only need to visit the restaurant, eat, and then make a payment. There are no dishes to wash here.

Cloud Computing Platforms

Clients are being twisted by cloud-based platforms that improve the attractiveness of how application functionality is supplied.

Cloud-based applications increasingly resemble platforms, which indicates that they are growing technologically and starting to sprout APIs, libraries, or even programming models.

One may consider all of these developments in developing technologies to be platforms for cloud-based applications. Like conventional platforms, cloud computing platforms provide tools that enable developers to build new apps that use already-existing features on free Cloud Computing course. After all, these platform tools can be freely accessed over the Web or through an operating system or bundle installed on a local machine. A web browser is required to utilize the app.

The rapid development of the opportunities provided by this kind of platform service has been fuelled by the popularity of mash-ups, which are websites or applications that combine tools from different cloud computing platforms without requiring the user to install additional software or tools in local computers to create new functionality.

The utilization of various cloud computing platform technologies in modern technology, such as Google’s search API, allows developers to integrate the functionality of that search engine into their applications.

Platform-as-a-Service (PaaS)

PaaS refers to using a platform on which developed applications are made available as a service online.

It’s a setting where programmers construct apps using programming tools provided by a service provider and then publish them in the cloud. Customers may access the application online as a service hosted by the host. An excellent API is made available by the PaaS provider for building and enhancing specific apps. The PaaS provider is also accountable for the daily upkeep, management, and support of the deployed application and each client’s data. Examples include Google App Engine and the platform utilized.

Use Cases

PaaS suppliers provide customers with an environment in which hardware and infrastructure, as well as operating systems and servers, are taken care of, abstracting away much of the need to deal with servers.

Instead of investing in hardware and other resources, the organization may request as needed, growing as demand increases.

Infrastructure-As-A-Service (IaaS)

IaaS stands for Internet-based access to infrastructure, including application servers & storage servers. Infrastructure-as-a-Service consists of mainly automated and scalable computational resources that may be self-provisioned, metered, and made available on demand. It also includes cloud storage and network capabilities.

The foundational component of the cloud computing concept is service. Rack space, Microsoft Azure, AWS, and Digital Ocean are businesses that provide IaaS.

Use Cases

IaaS enables programmers to build their platforms and applications. A company can swiftly and effectively spin up more resources without investing in hardware. The typical payment structure for this approach is “pay as you use” or “pay as you expand.”

Software-as-a-Service (SaaS)

SaaS refers to an application hosted as a service offered to clients through the Internet.

Examples:

  1. CRM Salesforce
  2. MS CRM

Use Cases

When cost concerns a company, they often remove technical workers who are most inclined to install, administer, and update software to lower the cost of ownership and software licensing. SaaS offers a subscription model as a check against this. SaaS is bundled with IaaS; however, unlike IaaS, it does not allow the development of unique software.

Functions-as-a-Service (FaaS)

Functions-as-a-Service is a more recent cloud computing service that enables customers to autonomously create, modify, and execute programs without the burden of infrastructure development. It is related to designs for serverless computing.

Function categories:

  1. a web HTTP request is processed
  2. handle an MQ message (queue)
  3. queues for scheduling and processing
  4. manually executing procedures

Use Cases

  • Scale and isolate transactions with a large volume.
  • Burstable workloads: You don’t need to pay for a server if you use it once daily or monthly.
  • Task scheduling is a great approach to regularly executing a certain code.

Communication-as-a-Service (CaaS)

A contracted corporate communications solution is called communication-as-a-service. Vendors of CaaS are those that provide this kind of cloud-based service. The administration of the hardware and software needed to provide consumers with networking resources, including Voice over IP (VoIP) services, Instant Messaging (IM), free certificate courses, and video conferencing capabilities, falls within the purview of CaaS. With clearly stated SLAs, CaaS products ensure QoS (Quality of Service). Circuit diversity and redundant switching are additional features of the CaaS system.

Conclusion

The kind of cloud computing services you choose is determined by the amount of accountability and control you desire over the IT infrastructure. If you want a lot of control while employing cloud benefits like scalability, pricing, and disaster recovery, go with the IaaS approach. CaaS is beneficial in these IaaS scenarios if you want your developers to benefit from the simplicity of container orchestration. PaaS is ideal if you have the time, money, and resources to construct your software applications, including a talented team of engineers. Still, you do not wish to deal with the complexity and intricacy of setting up servers, networks, and databases. FaaS is appropriate for high-volume transactions, particularly for software that experiences spikes in demand and has to be quickly scaled up, and for applications that are run dynamically or regularly.
