Why use Cloud Computing? Advantages and Disadvantages

Hello guys, If you are curious about Cloud computing and why every company, both big and small, is going to be cloud-native, you have come to the right place. In the past, I have shared the best Cloud Computing courses and both free and paid courses to learn about popular cloud platforms like AWS, GCP, and Azure. In this article, I am going back to basics and telling you about what is cloud computing and what benefits it offers. Cloud Computing has been a buzzword in the IT world for the last few years. When it first appeared, like many things, a lot of people has dismissed it as being the next big thing, but cloud computing has certainly lived up to expectations and truly shifted how the Information technology arm of business functions today.
Cloud Computing is made of two terms Cloud and Computing; the first term refers to its flexibility in terms of moving around and scaling up (or down) on the fly, without affecting end-users, rather like a cloud.

The second term is obviously more obvious, it refers to taking advantage of computers for real-world calculations. In fact, cloud computing is similar to distributed computing, which is a program that runs on many connected computers to produce a result.

Types of Cloud Computing

Cloud computing comes in different flavors tailored based to the client's need. Some companies might just want to use clouds for infrastructure, some may want hardware as well as software, some just want software, and others may want everything.

By the way, SasS (software as a service) and PasS (platform as a service) are two of the most popular cloud computing services.
  1. SaaS (software as a service)
  2. PaaS (platform as a service)
  3. IaaS (infrastructure as a service)
  4. HaaS (hardware as a service)
  5. EaaS (Everything as a service).

If you are new to Cloud and AWS and looking for some online courses to learn Amazon Web Service, you can also check the Introduction to Cloud Computing on AWS course on Udemy. It's completely free and provides a simple, conceptual introduction to the concepts of Cloud Computing and Amazon Web Services.

Why use Cloud Computing? Advantages and Disadvantages

Advantages of Cloud Computing

Here are some of the main advantages of cloud computing, which will help you to decide whether to move onto clouds or not.

1) No worry to maintain Infrastructure

2) Cost Benefits

3) Backup and Recovery

4) Reliability

5) Scalability

6) Convenience

7) Environment Friendly

8) Resiliency, Redundancy and High Availability

9) Performance

10) Reduced Time to market

11) Increased Storage Capacity

12) Location Independence

These are just the tip of the iceberg; there are many more advantages of Cloud computing that you can learn by joining a comprehensive cloud computing course. If you are looking for a free course, I suggest you check out Cloud Computing Concepts on Coursera; it's a great course to learn about Cloud computing in depth from beginner's point of view.

By the way, when it comes to joining this course, you have two options, you can either join this course alone which costs around $39 per month for specialization, you can also join Coursera Plus, a subscription plan from Coursera which gives you unlimited access to their most popular courses, specialization, professional certificate, and guided projects. 

Disadvantages of Cloud Computing

There is nothing like free lunch in this world. Everything has advantages and disadvantages and cloud computing is also no different. In the last section, we have seen some big benefits of moving to clouds but let's now analyze some cons of cloud computing.

1) Regulatory Requirement

2) Privacy and Security of Confidential data

3) Latency

4) Vendor Dependency

6) Limited or No Control

7) Increased Vulnerability

That's all about the advantages and disadvantages of cloud computing. You can see cloud computing has serious pros to offer, and the way it’s going, I am sure the list of cons will be reduced. Cloud computing's growth is natural, and it's coming from the real need of people and small scale companies, start-ups who cannot afford to set up and run their own data centers and in many cases, only need high availability, recovery, and resiliency for their services.

If they turn out lucky and need to scale quickly, they can easily do it using trusted and matured cloud computing companies like Amazon web services. It's a win for both service providers and customers and works best for biggies like Amazon and Google, who has built their cloud infrastructure for their own personal need rather than keeping cloud computing business in their mind.

In short, Cloud computing offers a cost-effective solution for the infrastructure, platform, and software needs of people and companies that aim to provide the same services as biggies but can't afford massive data center costs.
