Question

What are the advantages and disadvantages of cloud computing?

​

Answer 1

Advantages of Cloud Computing

Cost Savings

Perhaps, the most significant cloud computing benefit is in terms of IT cost savings. Businesses, no matter what their type or size, exist to earn money while keeping capital and operational expenses to a minimum. With cloud computing, you can save substantial capital costs with zero in-house server storage and application requirements. The lack of on-premises infrastructure also removes their associated operational costs in the form of power, air conditioning and administration costs. You pay for what is used and disengage whenever you like - there is no invested IT capital to worry about. It’s a common misconception that only large businesses can afford to use the cloud, when in fact, cloud services are extremely affordable for smaller businesses.

Reliability

With a managed service platform, cloud computing is much more reliable and consistent than in-house IT infrastructure. Most providers offer a Service Level Agreement which guarantees 24/7/365 and 99.99% availability. Your organization can benefit from a massive pool of redundant IT resources, as well as quick failover mechanism - if a server fails, hosted applications and services can easily be transited to any of the available servers.

Manageability

Cloud computing provides enhanced and simplified IT management and maintenance capabilities through central administration of resources, vendor managed infrastructure and SLA backed agreements. IT infrastructure updates and maintenance are eliminated, as all resources are maintained by the service provider. You enjoy a simple web-based user interface for accessing software, applications and services – without the need for installation - and an SLA ensures the timely and guaranteed delivery, management and maintenance of your IT services.

Disadvantages of Cloud Computing

Downtime

As cloud service providers take care of a number of clients each day, they can become overwhelmed and may even come up against technical outages. This can lead to your business processes being temporarily suspended. Additionally, if your internet connection is offline, you will not be able to access any of your applications, server or data from the cloud.

Security

Although cloud service providers implement the best security standards and industry certifications, storing data and important files on external service providers always opens up risks. Using cloud-powered technologies means you need to provide your service provider with access to important business data. Meanwhile, being a public service opens up cloud service providers to security challenges on a routine basis. The ease in procuring and accessing cloud services can also give nefarious users the ability to scan, identify and exploit loopholes and vulnerabilities within a system. For instance, in a multi-tenant cloud architecture where multiple users are hosted on the same server, a hacker might try to break into the data of other users hosted and stored on the same server. However, such exploits and loopholes are not likely to surface, and the likelihood of a compromise is not great.

Hope it helps you :)

                     Cloud computing

Cloud computing is on-demand service provided by various organisations and companies. The main motive of the cloud computing is to give high speed internet facility, Low cost usage, Best cloud gaming, High specs PC usage  to users. Organisations first established their computer and servers in Server farm in different locations , and they made it available to all users.

In short, Cloud computing is a term that provides the use of data centers to users. This organisations established their various servers and cloud storage services; This helps them to run the cloud computing very smoothly. As Cloud computing provides us High speed internet, Integrated and High PC specs,  Low cost usage, Cloud gaming, Storage devices and hardware visualization, Cloud computing has achieved their best place all over the world.

We can compute to our account created in Cloud computing organisation. This organisations have established their difference services for different uses. Like Cloud computing for online browsing and gaming at high speed and low cost, Online data storage; This provides users online data storage to store their data digitally. Various Tech Giants companies stores their data in the services like this. This is helpful to various users, If our data is deleted from our PC or server, then we can recover it through this service which is very addition point.

What is Visualization in cloud computing ?

Visualization is a creation of Virtual Hologram anything. Like Server, Desktop, Computing, Internet Facility. In short, Virtualization is a technique, which allows organizations share a single physical instance.

Types of Virtualization:

• Hardware Virtualization.

• Operating system Virtualization.

• Server Virtualization.

• Storage Virtualization.

Visualization plays very important role in cloud computing, As it provides most important thing, Connection between Clients and users. If any company releases the next version of their application, then by the process of Visualization, Cloud computing provides us the latest version to use.

In addition, This cloud services have their 2 different server points. Means, If their any server location is damaged or any technical error is occurred, then they use other server. This servers are programmed in Linux operating system, as it is very fast and efficient, various cloud services uses Linux OS.

There are two types of Cloud computing; Public and private

Public - Data is made available to all users from their official homepage.

Private - Data is private; No one can read and steal it.

How cloud computing works ?

To understand it in better way, I am classifying cloud computing in 2 different types. - Front end and back end.

Back end of the computer is connected to the network physically and Back end is connected to users or clients.

The back end is everything in the term "Cloud". Back end consists of Data storage servers, Internet, Network, Database, Computing, monitoring, Content, Block storage, Collaboration, Run-time and everything database. And later, This data is provided to users and clients by their High speed internet facilities.

What is Cloud Gaming ?

Cloud gaming is a similar service like cloud computing announced by Google in their I/O event 2018. Cloud gaming services provides us high speed cloud internet, Highly advanced PC specs and Best monitoring to run and play Games.

This service has been officially started to roll-out all over the world by 2019, Google firstly launched this service, It aims to give the best gaming performance to Users and Clients on their smartphones, TVs and old laptops.

And, According to a survey, Cloud gaming is going to be future of the Gaming consoles. Most of the gaming consoles like XBOX, PS4, Google are struggling on making Cloud Gaming more smoother and more reliable.
