Why is Cloud Computing so needed? It can be due to market uncertainty or high software, hardware, and infrastructure costs. It also can be because of resource limits and security issues. Yet, those are only some problems business owners need help scaling up their businesses. As you can see, they represent an extremely high investment cost, which is a significant risk for them. These are just some of the main reasons Cloud Computing came into play. 

Amazon Web Services defines cloud computing as the on-demand delivery of IT resources. In other words, the only cost you need to worry about is the cost you incur. The best part is the benefits of Cloud Computing aren’t limited to IT businesses. It has helped business owners from almost any industry, like healthcare, education, finance, manufacturing, and entertainment.

The truth is we, as users, also greatly benefit from cloud computing! Let me illustrate that with a quick example. Think about a situation where you travel abroad for a business meeting. You left your laptop behind and realized you have all your essential files and documents on your laptop. That would be a significant problem. Unless, of course, you have your files and documents stored in the cloud. That way, you can access anything from any device with an internet connection. 

Cloud storage is the primary data storage option for 65% of users. In addition, 60% of the world’s business data is in the cloud. That should give you a rough idea of why Cloud Computing is so popular and has taken over so quickly. In this post, we’ll cover all the ins and outs of Cloud Computing to inveil how something that good is even possible. 

What is Cloud Computing? 

Cloud Computing refers to the ability to deliver online computing pay-as-you-need services. These include servers, storage, databases, networking, software, and analytics. In simpler terms, it's storing and accessing data and apps online instead of a hard drive. There's something you are surely asking yourself. How is all that even possible? The fact that you don't need to get more hardware to expand your business doesn't mean it doesn't exist.

Cloud computing is possible thanks to companies that provide this kind of service. These companies are cloud service providers. They make some profit as you lower your expansion costs to a large extent. This technology has revolutionized our work and has become an integral part of our lives. It's worth mentioning that some cloud providers offer free services, like storage, perfect for individuals. A practical example is the popular email service Gmail provided by Google. Users can access their emails, attachments, and contacts from anywhere. Google's data centers store all the data; users can access it through the Gmail website or mobile app.

Cloud Computing IaaS, PaaS, and SaaS

There are three main Cloud models available with different abstraction levels. Thus, users can choose the level of control they need over their computing resources. 

What is a Cloud Computing IaaS?

Infrastructure as a Service (IaaS) is the most basic Cloud Computing model. It provides servers, storage, virtualization, and networking components through an on-demand platform. Users use these resources to build and deploy their applications. With IaaS, users care for apps, data, operating systems, runtime, and middleware. Examples of IaaS providers include AWS, Microsoft Azure, and Google Compute Engine.

What is a Cloud Computing PaaS?

PaaS (Platform as a Service) gives you a little less control over applications. It provides cloud platforms and runtime environments for developing, managing, and testing applications. Users don’t need to worry about the underlying infrastructure they need to deploy their apps. This model provides web servers, databases, middleware components, OS, and developer tools. They are pre-configured and managed by the provider. Among known PaaS providers, you can find Heroku, Google App Engine, and Microsoft Azure.

What is a Cloud Computing SaaS?

Software as a Service (SaaS) is a complete cloud service model. In other words, vendors have complete control of these functional software applications. SaaS providers care for everything; users interact with the application through a web browser or API. Examples of SaaS include Customer Relationship Management (CRM) and solutions like HubSpot and productivity suites like Microsoft Office 365, Adobe Creative Cloud, and Google Workspace. 

You’ve probably heard of deployment models in Cloud Computing. We’ve covered it already in this article! Yet, to clear any doubts, we’ll explain the idea with a practical example below. 

Cloud Computing Deployment Models

There are several deployment systems in Cloud Computing. Let’s explain how they work.

What is a Public Cloud?

A public cloud is similar to renting a public storage unit for your belongings. Anyone can rent a team and have access to the same storage space. Similarly, in a public cloud server, you store data on shared remote servers alongside the data of other users. 

What is a Private Cloud?

Here, you can store your belongings like in your personal storage unit. The difference is that, in private clouds, you have a dedicated space that you don't share with others. This method can be safer and give you more control over your data. Yet, it’s more expensive because you must manage and maintain the infrastructure.

What is a Hybrid Cloud?

Hybrid Clouds can be seen as having some of your belongings in a public storage unit while others lay in a private storage unit. Depending on your needs, a hybrid cloud can store some of your data in the public cloud and some in the private cloud. For example, you could store less sensitive data in the public cloud to save money. The other way around, sensitive data in the private cloud increases security.

Pros and Cons of Cloud Computing for Businesses

Let’s move to understand the pros and cons of Cloud Computing. We’ve listed them below:

Pros of Cloud Computing Cons of Cloud Computing
Scalability: Businesses of all sizes in almost any industry can scale their businesses as needed. Privacy: Security threats can compromise data, making it vital to choose the right tools and instruct teams.
Updates: Regardless of the model, cloud vendors handle all software updates—of course, limited to their offered tools. Reliance: Any disruption in connectivity can have severe consequences. Thus, Cloud Computing must be flexible.
Security: Cloud providers have strong measures to protect their customers' data from cyber threats. Migration: Moving from on-premise to the cloud can be daunting since it entails security, privacy, and compliance.
Accessibility: As mentioned in our previous example, you can access any tool in the cloud from any device.  Downtime: Cloud solutions providers strive to improve proficiency and guarantee results, yet service downtime is always a scenario.
Collaboration: Teams can improve productivity and efficiency using Cloud Computing tools. Some include real-time collaboration, file sharing, version control, access control, project management, etc. Compliance: Countries and industries have different, challenging to navigate rules and regulations, like the discrepancies between the EU’s General Data Protection Regulation (GDPR) and the CLOUD Act in the US.

Best Cloud Computing Software and Tools

We think distinguishing between cloud service providers and cloud-based tools is important. The difference is that the latter uses cloud technology from a third party to offer a new service. Now that we have established that, let’s take a look at some of the best for each category.

Cloud Service Providers

Amazon Web Services (AWS) is one of the most robust Cloud Computing platforms. It provides various services like storage, databases, analytics, and machine learning. Similar to AWS, Microsoft Azure is another major player in the Cloud Computing space. Azure excels in hybrid cloud, AI, and Machine Learning. Also, we can see Google Cloud Platform as a high contender here. Google's Cloud provides a wide range of services. These include computing, storage, and networking. GCP is well-known for its data analytics and ML capabilities.

Cloud-Based Tools

Slack is a widespread cloud-based communication and collaboration platform. In fact, our team uses Slack daily to improve communication and collaboration! Also, at the top of our list, we can see Salesforce’s cloud-based CRM to manage customer interactions and sales processes. Another example is Dropbox, a file-sharing and storage service that lets you access your files anywhere. It also allows users to do real-time collaborations.

Why is Cloud Computing Important?

Cloud Computing has become an essential part of the modern-day digital world. It has changed the way people access computing resources. Hence, cloud computing has made them more accessible, scalable, and with low maintenance costs. It has also enabled collaboration and new opportunities for businesses of all sizes. The usage of cloud computing services can only keep growing. According to AppsRunTheWorld, the Cloud apps market is to reach $168.6 billion by 2025!

Cloud-based services include tools like Virtual Machines, Databases, and Content Delivery Networks. Some even offer DevOps tools and services with Continuous Integration and Continuous Delivery pipelines. Cloud Computing can make businesses more profitable and our lives so much easier. However, the importance of Cloud Computing lies in scalability. Plenty of the largest businesses in the world wouldn’t have been able to grow without it! 

Conclusion

Cloud service environments are more than powerful tools that can improve productivity. It has become a must for almost every firm! Choosing a service would only care if you consider the types of cloud computing models and their efficacy to reach your goals!
