An overview on Cloud: How does “cloud” work?

Cloud is definitely a metaphor for the internet. The subject “cloud computing” is not at all new. In fact, every cloud symbol depicts a virtual space which connects users from all across the globe. It’s like sharing information through a chain of networks.

Going back to cloud computing, it refers to sharing resources, software through internet. In this data are stored on virtual servers, which are maintained by cloud server providers. As a personal computing user, details can be accessed via cloud through a secure internet connection.

“As per the statistics the global market size for cloud computing market is expected to reach $182,300 by 2024 and $36700 by 2019.”

 

What are the types of cloud computing?

There exist three main categories of cloud computing services.

  • Saas (Software as a service): It is an on-demand software offered on subscription basis and is centrally hosted. For example- Microsoft 365
  • PaaS (Platform as a service): It allows platform for customers to develop, run and manage applications without generating any kind of complexity associated with launching and developing app. For example-salesforce.com
  • IaaS (Infrastructure as Service): It offers high level of APIs used to de-reference underlying network details such as backup, security, physical computing services, scaling, data partition and location. It allows massive support to large number of customers with the ability to scale services. For example- Rackspace.

Cloud Computing Deployment Models

There are three basic cloud deployment models;

  • Public cloud: In this your data are stored in shared infrastructure. Though it provides complete isolation for the users to store their information, it is still advisable not to use public cloud for storage of sensitive documents.
  • Private cloud: The security features differs from the public cloud. In private cloud, your server will have just your applications. These are used by companies holding sensitive information. A private cloud is either provided by the cloud provider or you need to buy your own stack.
  • Hybrid cloud: It’s a combination of private and public cloud. It provides functionalities of both public and private cloud. So, if a company wants to store critical mission data, they can leap for hybrid integration.

 

Popular example for cloud computing services

There has been a significant improvement in the storage and saving system. You no longer use floppy disk, CD-Rom, USB drives to store documents.

You can easily access personal files from any corner with a strong internet connection. In cloud storage you use Dropbox, Backblaze and Box.com

Users can use the service from their laptop, tablet or any random PC. They can also edit documents making the user work easily from every other place.

As an individual user, the initial amount given for cloud storage is 5GB (free of cost) in icloud. For further storage you are asked to pay additional amount which are priced on the basis of monthly or yearly rates depending on the service requirements.

Few of the cloud computing examples are;

  • Backup: A storage unit where data is secure and infinite virtual storage is provided.
  • Big data analytics: It allows entity to analyze and store large quantity of structured, semi-structured and unstructured data to figure out underlying relationship.
  • File storage: This storage is unlimited. It provides ten times more than a local storage at same or even lesser price.

 

How does cloud computing actually work?

To understand the entire cloud computing system divide it into section: the front end and the back end, which are connected over a thorough network via Internet.

The back end is the ‘cloud’ section while the front end is used by the computer user. However, its not at all necessary that every cloud computing system has same user interface.

On the back end, there are several storage system and server that forms cloud. A cloud system potentially includes, data processing or any other computer programs with each of its own dedicated servers.

 

Who are the Cloud Storage Providers?

The major cloud providers of the world are AWS, Azure and GCP. Google owes GCP, while Microsoft owes Azure and Amazon owes AWS.

Google Cloud Platform: A growing cloud hosting company. It operated SAAS services such as Gmail and Google Drive.

Azure:  The second AWS specialized in providing PaaS service. For an instance, Visual studio and Office 365 are some of the services rendered by Microsoft and which are integrated to Azure Cloud.

Amazon Web Service (AWS): Biggest cloud service provider offering an overwhelming amount of services, with the massive share in the IaaS sector.

 

How to manage cloud storage?

If the entity has multiple clients than the demand for storage will be high. A physical server can be fooled by running independent operating system. This technique is known as server virtualization. This maximizes output of the individual servers.

 

Benefits of Cloud Computing

  • Pay-per-use-model: There is no situation of getting cheated. You will be paying what you use.
  • 24/7 support service: The support service is always available and online. There is no time boundaries for using the service. You can use it anywhere anytime.
  • Security: It has an amazing data security. For a critical mission data, local drives can wipe out the details while a cloud storage can prevent access.
  • Manageable: Only subscription fees need to be paid. All the maintenance, delivery and upgradation service are maintained by Cloud provider. It is entirely backed by Service Legal Agreement (SLA).
  • Scalable: Can be easily scaled up and down as per customer’s need. For an example, your website traffic is immensely high on Friday nights than you have the option of scaling the server on that particular day while scaling the server down on the other days.
