Cloud Computing Types: The 3 Services to Know (2023)<br />

Cloud Computing Types

Picture a massive food court, packed with a variety of stalls, each serving a different cuisine. Now, instead of food, imagine those stalls offering servers, storage, databases, and software. That’s cloud computing for you! A smorgasbord of tech resources, accessible anytime, anywhere.

Summary

Cloud computing is like a buffet of digital services – you access servers, storage, databases, and applications over the internet, pay only for what you use, and save the hassle of maintaining your own infrastructure.

Type 1 – Public Cloud: This is like a big amusement park open to everyone. You pay for the rides (services) you enjoy, with the assurance of safety and maintenance taken care of by professionals. Companies like Amazon, Google, and Microsoft offer public clouds, providing services to multiple clients.

Type 2 – Hybrid Cloud: Imagine having your private playground that also has a gate to that large amusement park. That’s hybrid cloud for you – a combination of private and public clouds. You keep sensitive data in your private cloud while tapping into the public cloud’s vast resources as needed.

Type 3 – Serverless Computing: This type of cloud computing is like hiring a taxi. You’re not worried about its maintenance or fuel; your focus is reaching your destination. Similarly, with serverless computing, developers focus on their application code, while the cloud provider manages the infrastructure.

Cloud Computing Types In-depth

Public Cloud

So, remember our big amusement park analogy? That’s right, the one where everyone can come, enjoy the rides, and leave without worrying about maintaining the park itself. In the realm of technology, that amusement park is what we refer to as the “Public Cloud.”

Just like the diverse crowd at the park, the Public Cloud is open to everyone, from small startups to large corporations. It’s a space where companies can store their data, run their applications, and even harness advanced tech tools without needing to own any of it. They can just hop onto the cloud (just as you’d hop onto a roller coaster) and let the cloud service provider (the park management) worry about the technical nitty-gritty.

Public Cloud providers are like these mega amusement park operators, but instead of rides, they offer a vast array of computing services. These include servers, storage, databases, networking, software, and even entire artificial intelligence platforms. Big names like Amazon Web Services (AWS), Google Cloud Platform (GCP), and Microsoft Azure lead the pack, serving millions of customers around the globe.

In a Public Cloud, resources are shared among all users, much like the rides in our amusement park are shared by all visitors. This model, often termed as multi-tenancy, allows costs to be kept low since the expense of maintaining and upgrading the infrastructure is spread across many users.

Now, you might be wondering, “is my data safe in this crowd?” That’s a valid concern. In our amusement park, security guards ensure safety. In the Public Cloud, there are cybersecurity professionals and advanced security protocols in place. While no system is entirely invulnerable, reputable Public Cloud providers invest heavily in security to protect their users’ data.

The beauty of the Public Cloud is its pay-as-you-go model. Imagine if, at the amusement park, you only had to pay for the rides you actually took, rather than a flat entry fee. That’s exactly how the Public Cloud works. You only pay for the resources you use, allowing businesses to scale up or down based on their needs. It’s like having an unlimited access pass to an amusement park, where you only get charged for the fun you experience!

To sum it up, the Public Cloud brings to the table the power of vast, shared resources, cost-effectiveness, and the convenience of letting someone else handle all the technical upkeep. Just like a day at the amusement park, it’s all about enjoying the ride and leaving the maintenance worries to the pros!

Hybrid Cloud

Think back to the analogy we used before – the private playground with a gate that opens up to a larger amusement park. That’s the perfect way to envision a “Hybrid Cloud.” It’s the best of both worlds, a mix of your private space and the boundless resources of a public amusement park.

Just like a playground owner who gets to choose which toys and games to keep in their private lot, organizations with a hybrid cloud have a “Private Cloud.” This is an exclusive space only they can access, and it’s perfect for storing sensitive information or running critical applications. It’s all under their control, just like a personal playground.

However, even the most generous playground can’t hold every type of game or cater to a sudden surge in playdates. That’s where the gate to the big amusement park comes in. In tech terms, the “Public Cloud” is just beyond this gate. It’s got seemingly limitless resources that can be accessed as and when needed.

Say there’s an unexpected crowd of kids ready to play (think of it as a sudden increase in data traffic or demand for resources). Instead of scrambling to accommodate them in your limited private playground, you simply open the gate and let them enjoy the vast amenities of the amusement park. In other words, you scale up using the public cloud. Once the crowd disperses, you scale back down. You’re charged only for the additional resources you used, just like paying for extra rides at the amusement park.

This freedom to move between private and public clouds as per necessity is what gives the Hybrid Cloud its name and its appeal. It provides flexibility, scalability, and cost-effectiveness. Plus, it’s all under one roof, or rather, under one sky!

Data and application portability is another key advantage. Imagine if you could move your favorite rides between your private playground and the public amusement park whenever you wish. That’s what Hybrid Cloud enables in the virtual world!

Now, just as security is crucial in both private playgrounds and public parks, hybrid cloud models prioritize strong security measures. Private cloud components are safeguarded under the organization’s direct control, while reputable public cloud providers offer robust security for their part of the infrastructure.

In a nutshell, the Hybrid Cloud, much like our combined private-public play space, offers the best of both worlds. It’s a solution that can cater to changing demands, protect sensitive data, and still provide access to vast resources when required. It truly is a playground for innovation and growth!

Serverless Computing

If you recall, we compared serverless computing to hiring a taxi. Just as you’re unconcerned with the car’s maintenance or fuel, serverless computing allows you to focus solely on your destination – in this case, creating and deploying your application.

Now, imagine you’re planning a road trip. Without a taxi, you’d need to ensure your car is fit for travel, check the oil, fuel up, and maybe even map your route. That’s a lot of extra work before you can even start your journey. In a similar vein, traditional cloud computing models require businesses to provision, scale, and maintain servers to run their applications. This can be time-consuming and deviate focus from the real task at hand: building great applications.

Enter serverless computing, your metaphorical taxi. With serverless computing, all the responsibilities of server management are handed off to the cloud service provider, just as a taxi driver takes care of the vehicle and navigation. Developers can simply write their code and deploy it without worrying about the underlying infrastructure. It’s all about the journey (the application development), not the vehicle maintenance (the servers).

But wait, there’s more! Serverless computing, like our taxi service, operates on a pay-as-you-go model. Imagine paying the taxi only for the miles it covers. Similarly, with serverless computing, you pay only for the actual compute time your application uses, not for idle server capacity. This can be a significant cost-saver, making it as economical as it is convenient.

An additional perk of this model is its automatic scaling feature. Picture a taxi service that magically expands and contracts the car size to accommodate the number of passengers – more space when there’s a crowd, and less when it’s just you. That’s what serverless computing offers: it automatically scales your applications based on incoming traffic. No more manual adjustments or guessing games!

But what about roadblocks, you might wonder? Just as a proficient taxi driver is equipped to handle the bumps and detours on the road, cloud providers ensure serverless environments are secure and highly available.

In conclusion, serverless computing lets you sit back and enjoy the ride, focusing on your destination (creating awesome applications) while someone else handles the driving (managing the infrastructure). It’s a game-changer in the world of cloud computing, providing efficiency, scalability, and a smooth ride to your digital destination!

Conclusions

To navigate the digital landscape of the 21st century, understanding the different types of cloud computing is crucial. Whether it’s the boundless, bustling Public Cloud, the best-of-both-worlds Hybrid Cloud, or the take-the-wheel-and-drive Serverless Computing, each brings unique benefits to the table. They’re like different kinds of amusement parks, each with their distinctive attractions, but all under the vast sky of computing. By knowing their features and advantages, businesses can make informed decisions on the right cloud model, ensuring a fun and efficient ride through the tech amusement park!

How to stay safe online:

  • Practice Strong Password Hygiene: Use a unique and complex password for each account. A password manager can help generate and store them. In addition, enable two-factor authentication (2FA) whenever available.
  • Invest in Your Safety: Buying the best antivirus for Windows 11 is key for your online security. A high-quality antivirus like Norton, McAfee, or Bitdefender will safeguard your PC from various online threats, including malware, ransomware, and spyware.
  • Be Wary of Phishing Attempts: Be cautious when receiving suspicious communications that ask for personal information. Legitimate businesses will never ask for sensitive details via email or text. Before clicking on any links, ensure the sender's authenticity.
  • Stay Informed. We cover a wide range of cybersecurity topics on our blog. And there are several credible sources offering threat reports and recommendations, such as NIST, CISA, FBI, ENISA, Symantec, Verizon, Cisco, Crowdstrike, and many more.
