Cloud computing, which allows users to access and use shared computing resources over the internet, comes in various forms, each with its own characteristics and use cases. The primary types of cloud computing are Public Cloud, Private Cloud, Hybrid Cloud, and Community Cloud. Let’s explore their differences:
- Public Cloud
- Definition: Public cloud services are provided by third-party providers over the public internet, making them available to anyone who wants to use or purchase them. They may be free or sold on-demand, allowing customers to pay only per usage for the CPU cycles, storage, or bandwidth they consume.
- Characteristics:
- Highly scalable and flexible.
- No need for users to purchase hardware, software, or supporting infrastructure, which is owned and managed by providers.
- Examples include AWS, Microsoft Azure, and Google Cloud Platform.
- Use Cases: Suitable for a wide range of applications, especially for small to medium-sized businesses that don’t require high-level customization of their IT infrastructure.
- Private Cloud
- Definition: A private cloud consists of computing resources used exclusively by one business or organization. The private cloud can be physically located at the organization’s on-site data center, or it can be hosted by a third-party service provider.
- Characteristics:
- Provides more control and customization.
- Higher security and privacy; operations are not shared with other organizations.
- Can be expensive due to capital expenditure, maintenance, and management.
- Use Cases: Ideal for organizations with high data security, privacy, and regulatory compliance needs, like financial institutions or government agencies.
- Hybrid Cloud
- Definition: Hybrid cloud combines public and private clouds, bound together by technology that allows data and applications to be shared between them. It offers greater flexibility and optimization of existing infrastructure, security, and compliance.
- Characteristics:
- Offers a mix of on-premises, private cloud, and public cloud services with orchestration between the platforms.
- Provides more deployment options and greater flexibility to move workloads between cloud solutions as needs and costs fluctuate.
- Use Cases: Useful for businesses with dynamic or highly changeable workloads, for example, a business might use the public cloud for high-volume, lower-security needs such as web-based email, and the private cloud for sensitive, business-critical operations like financial reporting.
- Community Cloud
- Definition: A community cloud is shared among several organizations from a specific community with common concerns (security, compliance, jurisdiction, etc.), whether managed internally or by a third-party, and hosted internally or externally.
- Characteristics:
- It is a multi-tenant setup that is shared among several organizations.
- Balances the lack of control of a public cloud with the more customized capabilities of a private cloud.
- Use Cases: Ideal for organizations working on joint projects, applications, or research, which requires a central cloud environment for data sharing and management but are still subject to stringent privacy, security, or regulatory requirements.
Each type of cloud computing offers distinct advantages and disadvantages, and the choice depends on the specific needs and goals of the user or organization.

My students are the reason this website exists, crafted with the affection and dedication they’ve shown. ❤️
Clear lessons, easy to follow even for a beginner. Very knowledgeable and gives great encouragement to beginner coders. Really helpful and responded to questions quickly. No problem too big or too small. Friendly teaching style meant I didn’t feel embarrassed to ask silly questions.
Louise
I like your jokes. It was always nice how you made us giggle sometimes. Your responsiveness was super appreciated and i loved the additional resources. I think it was nice that you spoke slowly and clearly
Elizaveta
First, Anuj makes efforts to simplify explanations of a concept and gives practical examples in a structured way. Second, he doesn’t just teach us things. He takes time to listen to our concerns and motivates us by sharing his personal experience and thoughts as an experienced software engineer.
Amanda Kartikasari
The presentations you prepare yourself are much more information dense, available and I found some topics are much easier to grasp using them, so grateful for the extra materials you always provide.
Asya Seagrave
Very thorough in terms of showing how to get the code to initially work and what the different errors could be, as well as how to fix them. Very efficient teaching style!
Cerys Cullen
Really liked your teaching style, always very clear and you explained things nice and simply which was great when learning a brand new topic! Loved your videos which were concise, easy to follow and super helpful for going back over to practice with. Loved all the extra resources you provided, your blog, and just in general how helpful and passionate you are about what you do! Thank you so much!
Megan Bradley
Anuj was a clear and concise instructor, who was always happy to help no matter the timing of it. I also liked that he made everyone feel welcome and fostered an inclusive culture, which made our team not afraid to present even if we were slightly unsure if our project work would live up the the standard of the rest of the group.
Deni Hancox
The style of the learning structure has been very constructive and the availabilityof the instructor helps to build confidence and security to try, fail and learn. 5 stars to the instructor style!
Maryl Duprat
Anuj was a fantastic instructor, super informative and knowledgeable. He was very approachable with questions, and clear and concise in his explanations. 🙂
Alice Pinch
Anuj is a great instructor who is very knowledgeable and passionate about what he teaches. He worked well with his co-instructor, which led to a positive learning experience. The course itself is an introductory course but still has a lot of material to cover, but Anuj was very meticulous in explaining concepts to ensure lessons were executed and understood. He is a great listener and always willing to answer questions no matter how obvious (and sometimes silly). I have already signed up for another course and am hoping he will be part of the team!
Pam
Well-structured lessons with the use of diagrams/images to help students understand concepts. Demonstrated examples step-by-step and answered any queries students had.
Maria
Anuj is a great instructor, who was incredibly dedicated to the course, both during teaching hours and after them. I really enjoyed the fun material he posted after the sessions, such as games and fun facts on our Slack channel. I highly appreciate that he was always responsive and patient with any queries or questions that I had, and so any confusions were very temporary.
Raimunda Bukartaite
Really engaging and helpful, always happy to answer any questions I had!
Muskaan
I really liked that the classes involved solving problems during the class and it wasn’t a person speaking alone all the time. I really appreciated the support and commitment of the instructors during the whole course.
Victoria Caballero
Instructions were really clear, and Anuj was very encouraging. He was always open to answering questions and very patient with the class.
Rashida Adekunle
Clear instructions and useful coding habits highlighted.
Asnath Lubanza
Always very helpful – going an extra mile to aid students. Always welcomes questions and will not make you feel bad or stupid for asking.
Maria
Patient when teaching, explains everything clearly and simply for non-techies(!), willing to go slower if us students find it fast or hard to keep up or understand, willing to go over topics and ensure everyone understands. Anuj goes above and beyond for the students despite understanding and learning differences. Outside of class and after class – a passionate and great teacher.
Ameera
Really enjoyed coding alongside you, clear and concise instructions and even some bits that were necessarily on the slides, but were SUPER helpful to us and our understanding of the language
Francessca
Very informative, supportive and friendly. The latter made you very approachable so I felt more at ease asking for help with things.
Amy Mulligan
I found the use cases made things very easy to follow and understand – when I was learning by myself, I was confused at some of the concepts because I couldn’t see how they would be applied, whereas you gave real-life examples that really helped it slot together!
Anastasija Medvedeva
Very supportive, very clear and gives great demonstrations and examples. The extra slides and YouTube videos were also a huge help for me.
Daisy Dobson
I liked that you walked through what you were writing for the code and showed different expamples for the same concept
