Introduction

Cloud Computing Concepts, Technology, & Architecture

Cloud computing, or simply cloud, represents the delivery of hosted services over the Internet via a network of remote servers, accessed through standard and usually open protocols such as TCP/IP, HTTP, and XML-RPC.

computing involves the deployment of cloud infrastructure, an abstraction layer on top of physical hardware and software, to manage servers and other resources used in cloud computing environments.

This infrastructure-as-a-service (IaaS) layer provides users with on-demand access to systems that can be rapidly provisioned with minimal management effort.

What is Cloud Computing?

The term cloud computing generally refers to the delivery of computing services over the internet. Cloud Computing is an umbrella term for a variety of different types of computing technologies.

The most common technologies are web-based applications and storage services. These cloud applications may reside on a company’s servers, or they may be hosted by a third party.

two main types of cloud service providers are Infrastructure as a Service (IaaS) and Platform as a Service (PaaS). IaaS provides virtualized computers that users can provide as needed,

while PaaS provides software platforms for online application development. Google Docs is an example of an IaaS service, while Salesforce is an example of a PaaS provider.

Benefits of Cloud Computing

Cloud Computing Concepts, Technology, & Architecture

If you’re in the market for a web host or just trying to figure out what the heck cloud computing is all about, this blog post is for you.

We’ll take a look at some of the benefits of cloud computing and look at how it can change your company’s bottom line.

The term cloud refers to remote servers that hold data.

When people refer to cloud computing they are usually talking about services like Gmail and Dropbox that store your data on a remote server somewhere

so that you can access it from any device with internet access.

It’s convenient because your data lives on the server so when you switch devices or replace a laptop, phone, or tablet all of your stuff is still there!

Types of Clouds

The three types of clouds are public, private, and hybrid. Public clouds are typically accessed by the general public without restriction. Private cloud computing is accessible only by an organization’s internal staff members.

A hybrid cloud is a combination of two or more of the other two types of clouds.

Organizations will typically use different types of clouds to meet their specific needs and requirements.

Public Clouds

A public cloud is a type of cloud computing service where the provider rents out physical or virtual computing resources over the internet.

This allows clients to access these resources from any device that has an internet connection.

Public cloud services are typically billed on a pay-as-you-go basis and are made up of three main components: infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS).

Infrastructure as a service describes the underlying hardware infrastructure provided by the public cloud provider.

Platforms include software development tools such as programming languages, frameworks, libraries, and services for storage, backup, and other tasks.

Private Clouds

A private cloud is an IT infrastructure that relies on the use of virtualization to provide the company with a private version of the public cloud.

Private clouds can be hosted in-house or by third-party providers. For example, if Company A wants to have its own internal IT department and has enough money to invest in it,

It might set up a private cloud that is accessible only to Company A employees. Alternatively, Company B may choose not to have an in-house

IT department and instead rely on a third-party provider for its private cloud needs.

Hybrid Clouds

Most people are familiar with the concept of a private cloud – this is when you build a cloud environment in-house to address your data storage needs.

A public cloud is where you can offload storage and computing requirements to a third party.

Hybrid clouds are an amalgamation of the two types of clouds, typically blending on-premises infrastructure with an external provider.

Hybrid clouds offer the best of both worlds because they provide access to more resources without having to completely outsource your workloads. They also allow for more flexibility since you can adjust your computing power as needed.

Community Clouds

A community cloud is a collaborative effort by different organizations to pool their resources to build a shared infrastructure that is used to store and compute data. The resulting cloud computing environment provides benefits for its participants. For example, it can reduce the costs of owning and managing infrastructure. It also allows data processing and analysis tasks to be allocated among members of the group in a way that’s most efficient for the type of research being done.

Cloud Deployment Models

The decision to use cloud computing is not always easy. There are many factors to consider before committing and this is one of the major reasons why there are five different deployment models. Each model offers a different set of benefits and disadvantages depending on what the organization needs.

The five models can be broken down into Public, Private IaaS, Private PaaS, Hybrid, and Community Cloud.

All of these types have their advantages and disadvantages that need to be considered when deciding to move toward the cloud environment.

As with any IT decision, weighing all the pros and cons should be done before deciding which way to go.

Infrastructure as a Service (IaaS)

 

IaaS is the delivery of computing infrastructure over the internet. The IaaS provider manages hardware such as servers and storage devices but does not manage or maintain software applications. The IaaS provider delivers the computing resources for a fee, often with a pay-as-you-go subscription model.

Platform as a Service (PaaS)

PaaS is a type of cloud computing that provides a platform for building, testing, and deploying applications. The most well-known PaaS providers are Heroku and Google App Engine. This type of cloud computing generally has the lowest barrier to entry because it doesn’t require any specific knowledge of server configuration or programming languages. This makes it an ideal option for those just getting into development.
