Why Cloud computing is expanding ? 7 reasons for shifting to cloud computing

Read

Cloud computing, the term is defined as the-on-demand availability of the resources like storage , compute services , virtual machines all are provided by a hosted service provider over the Internet. Cloud is the technology that every industry, start-ups ,small businesses and Reputed companies like Amazon , Microsoft , Oracle , Alibaba , IBM and many more other companies leveraging this technology , even many of them Offer the cloud computing services to others as well, will talk about this later on.First you should know about why we need Cloud computing for us ?

after seeing this short info graphic video you got the terms that makes cloud computing advantageous for the companies after that we will illustrate them briefly :

1.SCALABILITY :

Scalability in cloud computing can be defined as the ability to increase or decrease the IT resources as per our requirements.In just few seconds you can scale up the storage and use other compute services as well . we can increase the virtual machines too in our system. In this we can customize the infrastructure according to the customer's need as well.

Vertical scaling :

In the vertical scaling we basically add more resources to the existing system or adding more power to the system with the same code. we will add more power to the CPU/RAM and we can also scale up the storage as per system need. here we only add up the things rather to extend the nodes.

Horizontal scaling :

In the horizontal scaling we will add the extra nodes to the system , the virtual machines altered as per the user needs. in this we can split up the servers for limiting the number of

requests that landing up one a single server.

scalability is the major advantage of cloud computing that's why companies are leveraging this technology to make their markets more agile.

2. Software at best :

In the cloud computing software as service provides us software applications over the internet

on demand and on a subscription bases . cloud providers host and manage these software to the underlying infrastructure and upgraded to security patches accordance to the time . In service models Saas includes all the facilities like : database management , operating system , servers , storage and firewalls security too . SaaS allows organization to running app quickly at minimal upfront cost.

3. Availability of services :

cloud services always available for their users , they are always at up-time for their users . Users can access their data or documents from anywhere in world as long as they are connected to a internet connection and same implies for the Time. Services are always running from real time analysis to security and for the companies data too.

4. Analysis of Data :

When Adapting a new technology or new plans for the industry their risk exposures are high but using cloud real - time analysis and analyzing of few years data of the company they can predict and adapt new plans. By using IOT (Internet of things) they can leverage the use of real-time analysis of data and keep an eye on their products too .This really helps companies differently in many ways .

5.Cost - Efficient :

Cloud computing is cost-efficient because here you only pay for what you use called as pay-as-you-go service.There are different strategic plans according to their prioritize business ideas. you can scale up and scale down your plans according to your uses.

6. Security Manager :

The very first fear is for companies that their data may be hacked. Security is something play a vital role for data protection.Cloud defend user's data by software and firewall and different security patches.Cloud also uses Data Encryption for the data so that only user can access the data. customers can also protect their data by keys too.security level cloud offers to their customers is appreciable.

7. Data management :

Cloud computing manages our data restores it and also keeps a backup so that company's data will not vanish in future. Governing the data also done by cloud computing. Data management is the really big responsibility when you work this on your own else cloud collects the practices , concept , procedures , systems to gain control of the data resources of the organization .

conclusion :

here , i will conclude that cloud computing is something that every industry should adopt for the betterment. they offer scalability for the scale up and scaling down the IT services.they turn up your work of managing the data , security , visualization , real world problem solver, the software at time with updated version and all management in to a single room.There are companies who provides cloud computing services to other users we will explain these topics in our upcoming articles on cloud computing stay tuned with us for this amazing series of cloud computing an upcoming - era.

Thank you everyone who share this knowledge with others and do tell us what we should cover in this cloud computing series.

Cloud computing

Cloud computing, also referred to as “the cloud,” is the delivery of on-demand computing
resources everything from applications to data centers—over the internet on a pay-for-use
basis as long as you connected to any network as well..

Cloud computing is a general term for anything that involves hosted services over the internet as for the pay as you service.
Examples of computing resources include networks,storage ,applications services and hosting as well

cloud computing consist of 3 major elements -

1. 5 Essential characteristics

2. 3 Deployment model

3. 3 Service model

5 Essential characteristics :

1. On-demand service :

On-demand Self-service, the 1st characteristic, means that you access to cloud resources such as the processing power, storage, and network you need,using a simple interface without requiring human interaction with each service provider.

2. Broad Network access :

In this, cloud computing resources can be accessed via the network through standard mechanisms and platforms such as mobile phones,tablets, laptops, and workstations.

3.Resource pooling :

In the resource pooling is an IT term that we use in cloud computing environment to describe a situation in which providers serve multiple clients , customers or "tenants" with provisional and scalable services.

It gives cloud providers economies of scale , which they pass on to their customers , making cloud cost-efficient . using multi -tenant model, computing resources are pooled to serve multiple consumers ; cloud resources are dynamically assigned and reassigned, according to demand , without customers needing to concern themselves with the physical location of the resources.

4. Rapid Elasticity :

This , implies that you can access more resources when you need them , and scale down when you don't , because resources are elastically provisioned and release.

5. Measured services :

Measured services , means that you only pay for what you use or reserve as you go ; if you're not using resource you're not paying . resource usage is monitored , measured , and reported transparently based on utilization.

3 Deployment services -

1. Public cloud :

Public cloud is when you leverage cloud services over the open internet on hardware owned by the cloud provider , but its usage is shared by other companies.The data stored in public cloud can be accessed by people around the world .

example - google derive is considered a public cloud service , where you can save the data & excess that data anywhere in the world just by good internet connection.

2. Private cloud :

private cloud means that the cloud infrastructure is provisioned for exclusive use by a single organization that means in simple terms it dedicated to only one organization its not accessible by the public it is purely dedicated . It could run on-premises or it could be owned , managed and operated by a service provider.

BONUS- Difference between public and private cloud

Although the concept of public and private cloud are similar , there are several differences is that a public cloud is available over the internet , while a private cloud is deployed through a firewall.

3. Hybrid :

Hybrid cloud basically a mix of both public and private clouds, working together seamlessly. companies can run a mission critical workload or sensitive applications on the private cloud to handle workload or spikes in demand by public cloud.

3 Service models :

1. Iaas :

In an Infrastructure as a model , you get access to infrastructure and physical computing resources such as , networking , storage and data center space - without the need to manage or operate them.

Infrastructure as a service basically like leasing a car. so if you ever leased a car, you probably did a lot of research , and you care about the specs of the car and their performance . you are also paying for the gas and any tolls or maintenance.

2. Paas :

In an platform as service model , you get access to the platform , that is the hardware and software tools , usually those needed to develop and deploy applications to user over the internet .

Platform as service is like , renting a car . when we rent the car we don't really care about the color and specs , in that we will pay for the gas and tolls.

3. Saas :

Software as a service is a software licensing and delivery model in which software and applications are centrally hosted and licensed on a subscription basis, and sometimes also referred to as "on-demand software."

Saas is basically most simple and easy to use service , its like taking an uber or ola and when we book our rides we don't care about anything , we don't pay for gas and tolls too

CONCLUSION-

In this post we explained the essential models of the cloud computing , by this you can now elect the best deployment service and service model for businesses . how you gonna use this effectively in your work . and by the end of this blog i want to know that which service and deployment you think most effectively work in this upcoming era ? --------
