What is Cloud Computing

Technology has massively changed the way we do things. For instance, you don’t need to go to the office to access specific resources. Besides that, you no longer need hard drives to store information. All these and many more can now be done in what is popularly known as “Cloud.” But what exactly is cloud computing, and what can it do? 

What is Cloud Computing? 

Cloud computing is basically the delivery of on-demanded computing services over the internet. Everything is effectively stored and conveniently accessed over the internet without the use of physical hard drives. 

Types of Cloud Computing Services 

Some several terms and phrases related to cloud computing. It is essential to understand what the cloud is computing for you to utilize its resources efficiently. To help you understand it better, here are the 3 main types of cloud computing services 

Software-as-a-Service (SaaS)

It’s currently the most common type of cloud computing service. SaaS has a massive user base, and it’s clear that most of us use it daily. Generally, you can access this model of cloud computing through a web browser or an app.  

Even though some SaaS services are free, others may need a monthly or annual subscription. But what makes this service quite popular, from this platform’s cloud computing definition, is clear that you don’t need to install software to use it. Besides that, you can conveniently access it anywhere at any time. Some of the most common types of SaaS services include: 

  • Dropbox 
  • Google Apps 
  • BigCommerce 
  • MailChimp 
  • Salesforce 

Platform-as-a-Service (PaaS) 

This is a cloud environment that’s specifically designed to support the development of web applications and their deployment. Generally, PaaS is usually used to support the full lifecycle of various applications. It’s efficient to help cloud users build, test, deploy, update, and manage the apps centrally. Examples of PaaS include: 

  • Windows Azure 
  • AWS Elastic Beanstalk 
  • Magento Commerce Cloud 
  • Google App Engine 

Infrastructure-as-a-Service 

These are cloud services that provide instant computing infrastructure. It should be noted that this infrastructure can only be managed or provisioned over the internet. For instance, an Infrastructure such as azure can be installed for the management of your own software. Common examples of IaaS include: 

  • Google Compute Engine 
  • Digital Ocean 
  • Amazon EC2

Working Process

Cloud computing services are usually decentralized in a particular place. This way, information can be efficiently shared with different users in various locations via satellite networks. Understand that every cloud application typically has a host. This includes hosting companies that are responsible for managing massive data centers that provide cloud computing security. 

When information is sent to the cloud, it’s the host company’s responsibility to ensure it’s protected. Besides that, the host needs to provide adequate storage space for the data. Some of the biggest companies that host the cloud include: 

  • Google – Google Drive 
  • Microsoft- Azure 
  • Apple -iCloud 
  • Amazon- Amazon Web Service 

Cloud computing’s delivery model involves the following key components: 

  • Public: Ideally, it’s the most common because it can be accessed from anywhere. You need to have the right application and login details. Examples include Apple, Google, Microsoft, and Amazon. 
  • Private: Specific users or companies usually use it for specified services such as data storage, hosting, etc. A private model has limited access. This means that it has more security layers compared to the public model. 
  • Hybrid: It’s a highly versatile model that combines the essential features of public and private models. Generally, it involves a combination of the two types of models over the internet. So users can conveniently access the appropriate resources they need.

Uses of Cloud Computing

There are so many uses of this internet resource service. Whether it’s an individual, group, or business, you can gain a lot from the different platforms. Some of the common uses include: 

  • Efficient communication and group communication: This usually facilitates by applications such as WhatsApp, Skype, and Zoom, among others 
  • Create cloud-native applications: You can quickly build and deploy or scale applications on the cloud; they may include web, mobile, and API. 
  • Store, back-up, and recovery data: It is highly effective in data storage. It’s not only cost-friendly, but the space is usually massive as well.  
  • Stream audio and video: Cloud-based applications can be used to access audio and video content from anywhere. This is due to the global-based design feature. 
  • Delivery of software on demand: With cloud computing, it’s now possible to deliver software on demand using SaaS. That’s why you can download or update the latest software version of different applications anytime and anywhere.  

Is Cloud Computing Really Important?

The benefits of cloud computing are significant. Basically, it has made the world to be a global village. You can talk and work with someone else in a totally different time zone in real-time. Cloud computing isn’t just crucial in current times, but it’s now essential. 

Apart from communication, data storage facilities have massively changed. Companies no longer have to store data and software in servers and hard drives physically. This would quickly result in data loss as well as lots of physical space. However, organizations can now conveniently store data in the cloud. They all need to scale the size if necessary. But with convenient sensitive data in the cloud, security is very much important. In recent times many high profile sensitive companies like HBO and Sony came under cybersecurity attacks. So cybersecurity measures are something businesses should also regard.

The Present and Future of Cloud Computing 

At the moment, it’s clear that cloud computing is an essential part of technology. It not only enhances productivity but also helps to accelerate the process of innovation. Its ability to streamline operations usually leads to an overall reduction in operation costs.

With the corona-virus pandemic, companies have been able to change and navigate through this global crisis. So, we are very optimistic about the future of cloud computing. We expect more organizations to make this the basis of their operations. It seems to be more flexible, reliable, secure, and scalable.

Final Thoughts

Cloud computing is here to stay and make things better. The idea of sharing resources over a network is highly effective in streamlining operations and enhancing communication. Besides that, it’s essential in enhancing security and reducing operation costs. Even though we can’t fully tell about the future, current trends indicate that it will continue evolving.
