04 Cloud Computing Architecture

Let's Cloud Series - 03 Cloud Computing ArchitectureThe Cloud Computing Architecture comprises of many Cloud Components, but we have two main parts of the Cloud Computing Architecture:

  • Front End
  • Back End

Each of them are connected through a network via Internet.

04 cloud computing architecure -  front end vs. back end

FRONT END

Refers to the client part of cloud computing system. It consists of interfaces and applications that are
required to access the cloud computing platforms.
Example: Web Browser.

BACK END

Refers to the cloud itself. It consists of all the resources required to provide cloud computing services. It
comprises of huge data storage, virtual machines, security mechanism, services, deployment models,
servers, etc.

03 Cloud Computing Technologies

Let's Cloud Series - 03 Cloud Computing TechnologiesThere are four technologies that work behind the Cloud Computing Platforms, making cloud computing reliable, flexible and usable, and these technologies are:

  • Virtualization
  • Service Oriented Architecture(SOA)
  • Grid Computing
  • Utility Computing

Virtualization

It’s a technique, which allows to share single physical instance of an application or resource among
multiple organizations or tenants (customers). It does so by assigning a logical name to a physical resource and providing a pointer to that physical resource when demanded.

And here’s a diagram to show the idea and sequence of Virtualization.part1-hardware-virtualization2

Service Oriented Architecture(SOA)

It  helps to use applications as a service for other applications regardless the type of vendor, product or technology. Therefore, it is possible to exchange of data between applications of different vendors without additional programming or making changes to services.

And this is a good reference, to know more about SOA deeply. LINK

Grid Computinggridcomputing

It’s a distributed computing in which a group of computers from multiple locations are connected with each other to achieve common objective. These computer resources are heterogeneous and geographically dispersed.
Grid Computing breaks complex task into smaller pieces. These smaller pieces are distributed to CPUs that reside
within the grid.
Grid size varies a considerable amount. Grids are a form of distributed computing whereby a Super Virtual Computer is composed of many networked loosely coupled computers acting together to perform large tasks.

Utility Computing

It’s based on Pay per Use model. It offers computational resources on demand as a metered service. Cloud computing, grid computing, and managed IT services are based on the concept of Utility computing.

IBM, HP and Microsoft were early leaders in the new field of utility computing, with their business units and researchers working on the architecture, payment and development challenges of the new computing model. Google, Amazon and others started to take the lead in 2008, as they established their own utility services for computing, storage and applications.

Utility computing can support grid computing which has the characteristic of very large computations or a sudden peaks in demand which are supported via a large number of computers.

 

 

 

Let’s Cloud Series | 02 Overview

Let's Cloud Series - 02 OverviewWhat is Cloud?

Cloud refers to a Network or Internet. In other words, we can say that Cloud is something, which is
present at remote location. Cloud can provide services over networks.

What is Cloud Computing?

Cloud Computing refers to manipulating, configuring, and accessing the applications online. It offers online
data storage, infrastructure and application.

Why Cloud? | Benefits:

  • You don’t have to install a piece of software on your local PC.
  • One can access applications as utilities, over the internet.
  • Manipulate and configure the application online at any time.
  • Cloud Computing offers online development and deployment tools, programming runtime environment
    through Platform as a Service model.
  • Cloud resources are available over the network in a manner that provides platform independent access to any
    type of clients.
  • Cloud Computing offers on-demand self-service. The resources can be used without interaction with cloud
    service provider.
  • Cloud Computing is highly cost effective because it operates at higher efficiency with greater utilization. It
    just requires an Internet connection.
  • Cloud Computing offers load balancing that makes it more reliable.

Let’s Cloud Series | 01 Introduction.

Let’s Cloud Series:

It’s a series of blog posts, that will cover many topics in Cloud Computing, starting from the scratch to advanced level in general. And then, we will post about Microsoft Azure as an Implementation of Cloud Computing Concept.
This series will take you a step-by-step approach while learning Cloud Computing Concepts .

Audience:

For whom is this series?
I’ts for absolute beginners who are really interested in Cloud Computing and Azure, and it’ll lead them to understand the basic-to-advanced concepts of Cloud Computing.

 

History:

The concept of Cloud Computing came into existence in 1950 with implementation of mainframe computers,
accessible via thin/static clients. Since then, cloud computing has been evolved from static clients to dynamic
ones from software to services.

Next blog post will cover an overview about Cloud Computing.
Stay tuned 🙂
