Cloud Computing- Everything You Need To Know

Cloud computing is a term made up of two words in which “cloud” is, used as a metaphor for the internet. In simple terms, cloud computing is saving and storing data files, and programs over the internet.

It is the on-demand availability of storing data and computing power without using active management. Generally, we used this term to describe data centers. There may be two kinds of clouds either personal or public. The one cloud which is limited to a single organization is called enterprise cloud while the one which is available for multiple organization is called public cloud which helps companies to avoid IT infrastructure tools.

It first came into existence in 2000.

With the help of cloud computing, one can have access to their files and application from any other device (which has proper internet access). It is an on-demand service available in data centers. In this application and services accessed through, web instead of the hard drive.

Computing cloud has the following essential characteristics

  • it does not require human interaction for any service, one can easily use computing capabilities.
  • All the capabilities are provided on the internet which you can use through your mobile, laptops, etc.
  • The capabilities can be available in any quantity at any time.
  • Cloud system have control on the use of resources which can be monitored, controlled and reported to both user and provider. The manufacturing organization pay for
  • It contains a feature called multi-tenancy which allows users to use the same application and infrastructure by keeping their information private and secure.
  • The servers are maintained easily and no downtime mostly. It contains a high-security system that secures the data of companies from hackers.
  • The user has access to the data, can easily upload data to the cloud or from the cloud to any device with an internet connection.
  • It allows users to buy extra storage for those who have storage issues in a very small amount.
  • It is the one-time investment like a company buys a storage place and can even sale some small storage place to other companies too just to lower their own cost.
  • In this one must pay for the service or for the space utilized by them.
  • In this one can easily and quickly upload their data.

Cloud computing benefits both hosts as well as a customer.

Following are the types of computing cloud:

Private cloud: 

It is that type in which cloud is used by a single organization contains multiple business units.

Community cloud:

This cloud infrastructure is used by the different organization who have the same requirements, missions. It is managed by more than one organization.

Public cloud:

This cloud is for open use by the general public. It may be managed by different organizations, business units, schools/colleges or any government organization. If the cloud is available in pay as you go manner, then it is called a public cloud.

Hybrid cloud:

It is a mixture of two or more clouds infrastructure.

Cloud computing is made up of applications one which delivered services over the internet and the other is system software that provides those services which are called software as a service (SaaS).  Service providers and users both get benefit from SaaS. Service providers can install, control and maintain the software while users can access the services anywhere anytime and can share data, store it safely in their infrastructure.

With provisioning point of view there are 3 new aspects in cloud computing:

  • Availability of infinite computing resources on demand which will quick enough which removes the need to plan for provisioning

  • Now the companies are allowed to start from where they want and need to like from small resources and increase the hardware resources if they need it.

  • Now it provides the ability that one can use computing resources on short terms like for one hour or day and have access to let the machines or storage go when they are no longer needed.

Following are the obstacles which may lead to the opportunity for cloud growth and development

  • Availability of services:

      For availability of services use multiple cloud providers otherwise organizations will disappoint and leave the cloud

  • Business continuity

Organizations expand their business for this they need more servers so introducing multiple cloud providers will help you to solve this issue.

  • Data confidentiality

Install VLANs, firewalls for the security purpose.

  • Quick scaling

Invent a scaler which relies on ML i.e auto scaler

  • Bugs in distribution systems

Install or invent a debugger for distribution systems

  • Scalable storage

The scalable store should be invented

  • Fate sharing reputation

Invent reputation guarding services especially for emails

  • Licensing for software

Pay-as-you-go should install or pay-for-use licenses to match the needs of cloud computing.

Due to cloud computing now, the organization does not need hardware or to pay workers for files, data.

Cloud computing is a development in the IT world.

The companies with a big task can get results as fast as their program can scale. Their elasticity of services without upgrading the customer to a premium scale is never done before in the history of IT. It is the delivering of application as services over the internet, hardware and system software which provides those services.

There are different and multiple definitions of cloud. A company can be a cloud computing provider if they have investments in large scale software infrastructure and have the operational expertise to run them. Some factors which influence the companies are:

  • Defend a franchise

  • Highest existing investment

  • Make a lot of money

  • Better customer relationships

Microsoft Azure is a cloud computing service that was created by Microsoft for managing, testing, developing applications through Microsoft data centers. It allows users to build an enterprise-class application without their own infrastructure. It is a public cloud computing using infrastructure as a service, platform as a service, software as a service for networking, storage, and virtual computing.

Microsoft azure certificate in Microsoft stack of products while Microsoft Azure developer certification is for those who develop, design and build cloud solutions.

Microsoft azure administrators are those who are responsible for maintaining Microsoft azure so the Microsoft Azure administrator certification is for them.
