Cloud technology ~ Everything about cloud computing A to Z

Posted on

The cloud runs on far-flung data centers. Which refers to data on hardware in a remote server. Also, the software and databases run on those servers. By using cloud technology users can access the same file and applications from wherever almost any device via the internet. If you want to log in to your twitter account on your new phone after your old phone breaks. Then you can find your account on a new phone with all your photos, videos, and chatting history. Because the storage and computing occur on servers in a data center on behalf of locally on the user device is the application of cloud technology.

What is cloud technology?


Cloud technology is a model of web-based processing. Whereby share computing resources such as servers, applications, services, storage, etc. On the other hand, it provides on-demand network access to data at each computer node anytime anywhere. As well as offering virtual resources and virtual computing platforms. We don’t know where and how resources exist.

Cloud service providers

The cloud computing service provider offers cloud computing-based services such as network, infrastructure, application, storage, and database services to businesses or individuals. Besides, clients send files to cloud data servers on behalf of storing them on their hard drives. Examples of services are Amazon web services, Kamatera, Rackspace, and Massive Grid.
Basic requirements for cloud technology and its applications


Users want their services to improve and available at any time. But computer systems will sometimes fail in this case. But, cloud technology implements a Disaster Recovery (DR) mechanism. Users can be moved from one data center to another properly by the service provider. But, users do not even have to know about it.


Users do not like to be limited to only one platform. But here, users can switch from one service provider to another. As well as able to move data and applications from one cloud to another.

Data Security

Security is the major requirement in cloud technology. It gives higher security features such as centralized monitoring, enhanced incidence detection, logging of all activity, centralized authentication testing, etc.


Customer admin must control the cloud infrastructure. Creating new accounts, allocating various services, user account monitoring must be under the control of the customers. That provides availability management, performance management, configuration management, security management of infrastructure, and applications.

Backup, storage and retrieval

Suitable data backup will offer when occurring emergency, corruption, natural disaster, power outages, and all other types of data loss.

Infrastructure as a Service (IaaS)

This provides virtualized computing resources over the cloud. IaaS provides to access computing infrastructures such as virtual machines, virtual storage, servers, networks, etc. IaaS used by network architects. Amazon web services, Microsoft Azure, and Google Compute Engine are some examples of IaaS. Reduce acquirements cost, pay for what you use, not peak capacity, and reduce environmental impact are some benefits of this.

Platform as a Service (PaaS)

PaaS is a cloud technology model. That provides tools necessary to develop, test, and organize different business applications. Furthermore, PaaS provides a runtime environment, development, and deployment tools for applications. PaaS is more useful for developers. Google App Engine,, and AWS Elastic Beanstalk are examples of PaaS.

Software as a Service (SaaS)

That gives quick access to the cloud-based web application. And hosts the software and make them available for the client over the internet. Uses by end-users. Email, Facebook, Twitter, virtual desktop, games are some examples of this. Famous SaaS offerings are Google Apps. This improves internal productivity and the rapid application of security.
Characteristic of Cloud Technology

High elasticity and scalability

Storage, networking, and compute assets can add or remove as needed. It also allows users to buy extra cloud storage for a very small amount.

Pay per use

The user has to pay only for the usage of services or space.

Automatic System

Cloud technology automatically analyses and monitors the data. As well as users can monitor, control, and report the usage.

Resource pooling

That means allows multiple customers to share the same physical infrastructure with the help of a multi-tenant model.
Device and location independence

Which means have large network access using the internet. Can access the data of the cloud by using any device at any time from anywhere using a web browser.

Easy maintenance

The servers can easily maintain. Also, downtime is very low. Sometimes no downtime.

On-demand self-service

This technology provides computer services like email, storage, and network without any interaction with each service provider. Here users can also analyze the computer capabilities.

Cost efficiency

Only pay for what is used. To that, reduce the cost of purchasing and maintaining actual equipment and infrastructure.
Reliability – If there is a fail in the current server, then you can easily transfer any other available servers. It is also more flexible.
Manageability – Provide central administration of resources. Because that can easily manage all the activities seamlessly.
Disasters Recovery – Data loss is a heavy problem for all organizations. Cloud-based services provide quick data recovery facilities. Then data is always available even if your device (laptop or mobile) damaged or when occurs natural disaster or power outages.


Availability and Reliability

Most of the businesses are dependent on third-party service providers. Therefore cloud systems should reliable and powerful.

Data management

Typically, data hosted in different locations. Therefore maintaining a cloud is not an easy task. Usually, business users easily change and update cloud services. So it is the responsibility of the service provider to manage the information and disseminate it throughout the businesses.

Security and privacy issues

This is the main challenge in this. Viruses and hacking users are major security problems. So security applications, encrypted file systems, and data loss software can apply to avoid these challenges.

Lack of knowledge and expertise

There is not sufficient knowledge to every business about the designing and implementation of cloud solutions. Lack of expert staff and tools for the better use of this technology is the main reason. It is hard to train staff about the process and tools of this.


We can transfer applications running on one platform to another new platform. Likewise, it should be implemented safely and correctly without doing any changes in designing and coding. But the portability is not possible at every time. Because different standard languages are used by each of the cloud providers.
Computing performance and cost barriers

Though the cost of actual infrastructure cut down by using this technology. Businesses have to spend a large amount of cost on high network bandwidth for data-intensive applications on the cloud. Otherwise, low bandwidth does not meet the arbitrary computing performance on cloud computing.

  1. Today, while I was at work, my cousin stole my iPad and tested to see if it can survive a 30 foot drop, just so she can be a youtube sensation. My iPad is now destroyed and she has 83 views. I know this is totally off topic but I had to share it with someone!

  2. Thanks for discussing your ideas listed here. The other element is that when a problem appears with a personal computer motherboard, people should not have some risk regarding repairing that themselves because if it is not done correctly it can lead to permanent damage to an entire laptop. It is almost always safe to approach your dealer of your laptop for your repair of that motherboard. They’ve already technicians who have an expertise in dealing with notebook computer motherboard issues and can have the right prognosis and carry out repairs.
