Cloud Computing Architecture?

Posted on: May 24th, 2018 by nexstepaz No Comments

The National Institute of Standards and Technology (NIST) says that cloud computing possesses different qualities. These are necessary to achieve delivery of server-based computing resources using digital networks available on both mobile and desktop platforms. In order to get a better understanding of this technology, it is necessary to look at its architecture and subcomponents. So, what is cloud computing architecture?

Cloud Computing Architecture

The execution of Cloud computing relies on a number of components and subcomponents, which on the whole is referred to as its architecture. The basic components of this architecture are the platforms, delivery system, and the network. All of these are critical in ensuring that content delivery in Cloud computing works for all its users.

Cloud Client Platforms

In general, the Cloud architecture can be divided into the Front End and Back End sections. These sections are designed to connect with each other using the Internet as its overall network.

The Front End section is represented by the user interface that appears on the computer screen of the client or user. The appearance may vary depending on whether a desktop computer or a mobile device is used. It is important to point out that not all computing systems that make use of the Cloud will have the same user interface.

The Back End section is what is actually known as the Cloud as far as the computing architecture is concerned. It is made up of the different resources needed to deliver the computing services. The Back End can include data storage facilities, computer servers, virtual machines, security protocols, including the services and the deployment model needed to ensure that the Cloud service can be provided.

When we talk about Cloud computing architecture we normally mean that the control, management, and delivery of the applications that emanate from a Cloud-based server. The data will be remotely replicated and preserved depending on the configuration of the Cloud. When you have an efficiently integrated Cloud system the possibilities and efficiencies can be virtually limitless.

Essential Contents

The most critical content of the Cloud server is its operating system because it makes possible the delivery of the various services. The operating system serves as the primary authority responsible for the operation of the different features of the Back End like its traffic control, security mechanisms, and protocols among others.

All other contents of the Cloud server would be useless without the operating system or more commonly known as the hypervisor. By guiding the communication protocols between the containers and the connected world outside, multiple guest virtual machines can run alongside each other without much problem.

The efficient operation of the central server focuses on the systematic review of all client requests to ensure that traffic flows smoothly. It also manages the running system to come up with the best possible way to serve all client requests effectively. There are three types of hypervisors:

  1. Native – these run directly on the server without using an in-between operating system;
  2. Embedded – integrated as a separate chip on the processor, these improve server performance; and
  3. Hosted –executed as a distinct layer of software above the operating system and the hardware to improve performance in both private and public Cloud environments.

Cloud Storage

A type of data storage model where logical pools are used for storing digital data. Multiple servers, and sometimes multiple locations are used for physical storage with a hosting company owning the physical components of the storage system and its environment.

Availability and accessibility of the data is the primary responsibility of the hosting company including the physical and virtual protection of the stored digital data.

Cloud-Based Delivery

Every content marketer should be aware of the content delivery system used by the Cloud. This is because the delivery model is a representation of a specific combination of IT resources that are offered by hosting providers. Normally there are three common models that have been formalized and established like:

  1. Infrastructure-as-a-Service (IaaS);
  2. Platform-as-a-Service (PaaS); and
  3. Software-as-a-Service (SaaS).

There are also other specialized variations of the delivery model that are characterized by the combination of distinct IT resources. This delivery model is also sometimes known as the Cloud Service Delivery primarily because every model can be classified as a different service offered by the Cloud.

Infrastructure as a Service (IaaS)

This particular delivery model takes the conventional physical hardware configuration of your computing system and takes it to the virtual world. For enterprises that are used to having its business process managed within the confines of their offices, some reservations may be felt when the computing goes to the Cloud.

However, with businesses paying a fee for the use of Cloud computing, the assurance of security, better networks, higher storage, and running of virtual servers can be expected from the Cloud. Businesses will also get the advantage of mitigating costs associated with maintaining hardware and data centers locally.

Platform as a service (PaaS)

Do you want to enhance your business productivity? Then you need to make sure that you have the right application platforms and databases available to you. This is primarily what PaaS is all about. In traditional computing environments, this represents the middleware that allows the end user to take full advantage of the computing power of the hardware and software components.

Software as a service (SaaS)

This Cloud delivery model focuses on the installation and maintenance of required software that the Cloud user needs. The software runs on the client side using the Internet or Intranet as the network of choice.

The client machine of the end user does not require any installation that is software specific. This is because everything runs from the Cloud server. The great thing about SaaS is that it is highly scalable so system administrators have the luxury of running applications on different servers. This is seen as a huge improvement from older delivery models where end users will buy and install the software on their own servers.

Getting rid of local installation helps minimize the maintenance cost and the upgrades of the software will normally be covered by the service fees paid to the hosting service.
