Today we all are working on software systems and everyone is aware of what is Cloud Computing technology and its benefits. Development leading to revolution – established IT now uses a variety of virtualization technologies to properly use substantial IT resources. Shifting to private clouds is another step in the data center development, in which existing infrastructures will be used and updated to provide cloud-based services. Additionally, public cloud services are getting tremendous market momentum today, as more and more businesses migrate their applications to third-party cloud providers. These public clouds are presently leading companies to further business limits.
You should understand cloud fundamentals which is a significant part when are about to start with Cloud Computing, like what is cloud computing, the benefits of adopting its types, and models of cloud deployment. You can consider the example of Amazon Web Services (AWS), which is one of the best cloud providers that deliver above 300 services. Many people who are new to this computing world, keep thinking about what is cloud computing and its benefits.
What is Cloud Computing?
Cloud Computing is described as collecting and accessing computing services and data across the internet. This Cloud computing provides you the option to convert IT infrastructure into a utility, which implies you can get into your IT infrastructure through the internet by utilizing computing resources on the cloud. Without the requirement to install or manage these resources on-premises. It does not save any data on your personal computer, instead, it is an on-demand availability of computer services such as data storage, servers, networking, databases, etc. The primary goal of cloud computing is to provide access to data centers for several users. Users can also get data from a remote server.
The reverse of on-premise is the cloud providers, who give you these services through the internet. Cloud providers are businesses that have their servers, hire IT people, pay, and maintain the real estate for those servers. Those firms provide you the opportunity to manage the configuration of these cloud services that you use, while they take care of the rest.
Benefits of Cloud Computing
We read what on-premise IT does, the conventional way of maintaining IT infrastructure. Based on the distinctions between provider and on-premise solutions, there are a few definite benefits of cloud computing that you get while using cloud resources:
1) Lower Cost of Ownership
Cost-saving remains one of the greatest Cloud Computing advantages. It supports you to save large capital costs as it does not require any physical hardware expenses. Also, you do not require any qualified personnel to manage the hardware. The purchasing and managing of equipment are done by the cloud service provider.
2) Performance and Scale
These are the two most significant benefits of cloud computing that you will get when shifting to cloud technologies. Whenever you desire that your consumers should have an amazing user experience utilizing your product, anywhere.
Cloud computing services operate on a global network so that they can give you the capability to scale and deliver the resources when they’re required.
3) High Speed
What is cloud computing -High Speed. Let’s check, it enables you to use your service instantly with some clicks. This accelerated deployment permits you to get all the required resources for your system within fewer minutes. In only a few clicks you’re ready to get up and running the computing resources you require for all your applications.
4) Reliability and Unlimited Storage Capability
Reliability is one of the most significant benefits of cloud computing. You can get instantly updated about any changes. This cloud also gives nearly unlimited storage capacity. You can instantly expand your storage capacity at any time with very nominal monthly charges.
5) Faster Deployment
It provides you the benefit of fast deployment. Therefore, when you choose to use the cloud, your complete system can be entirely functional in very few minutes. Although, the amount of time needed depends on what sort of technologies are employed within your business.
What are the Security Risks of Cloud Computing?
Although Cloud offers several advantages, like excellent accessibility, improved collaboration, Storage capacity, Mobility, etc. But there are also security risks involved in the cloud. Let us look at some of the most common security risks of Cloud Computing:
1) Data Loss and Data Breach
Data loss is the most widespread cloud security risk of cloud computing. It is also recognized as data leakage. During data loss, data is being corrupted, deleted, or becomes unreadable by users, applications, or software. In a cloud ecosystem, data loss happens when any sensitive data is in somebody else’s hands, the hard disk is not working correctly, or if the software is not updated.
Data Breach occurs when any confidential data is accessed, seen, or stolen by a third party without any authorization, so an organization’s data is hacked by hackers.
2) Insecure APIs and Hacked Interfaces
As we all understand, what is cloud computing and how it depends on Internet, so it is necessary to defend APIs and interfaces used by external users. The easiest method to communicate with most of the cloud services is with the use of APIs. In cloud computing, some services are available in the public domain and these services can be easily accessed by third parties. Therefore, there is a chance that these services are easily hacked and harmed by hackers.
3) Vendor Lock-In
Vendor lock-in is the of the biggest security risks of cloud computing. Businesses encounter problems while transferring their services from one vendor to another. As different platforms are provided by different vendors which can cause difficulty and problems while moving from one cloud to another.
4) Denial of Service Attacks
When the system gets too much traffic to buffer the server then Denial of service (DoS) attacks occur. DoS attackers mostly target web servers of big organizations such as media companies, banking sectors, and other government organizations. To retrieve the lost data, DoS attackers charge a huge deal of money and time to handle that data.
5) Account Hijacking
Account hijacking is a severe security risk of cloud computing. It is the process within which an individual user’s or organization’s cloud account like an e-mail account, bank account, or social media account is stolen by hackers. The hackers utilize this stolen account to conduct various illegal and unauthorized activities.
Cloud technology today provides a variety of possibilities and opportunities for businesses, researchers, independent developers, professors, and students. By understanding and learning the different services, benefits, models, and risks offered by the cloud, users can make informed decisions regarding how to completely take advantage of what is cloud computing offers.
