Cloud Computing concepts, advantages, disadvantages

Cloud computing has been gaining popularity in the world of technology due to its ease of deployment, reducing the impact on server administration and additional equipment. It allows companies and users to manage resources from anywhere with an internet connection. 

‍

There are three basic concepts of cloud computing:

‍

• IaaS (Infrastructure as a Service): This model involves renting infrastructure resources like virtualization, storage, and networking. It's akin to paying for utilities in a home - you only pay for what you use.
• PaaS (Platform as a Service): PaaS provides essential tools for application development, deployment, and management. Notable examples include Amazon S3, Heroku, and Google App Engine.
• SaaS (Software as a Service): SaaS offers application usage and subscription-based billing. Popular SaaS examples are Office 365, Gmail, Google Docs, and Trello.

Benefits of Cloud Computing

Cloud computing offers several benefits that help businesses save costs and time while improving efficiency. Below are some of the advantages of cloud computing:

‍

Cost Savings:

One of the significant benefits of cloud computing is cost savings. In the cloud, you only pay for the resources you use. You don't have to purchase servers or other computing equipment to deploy your applications. The cost of server administration is implicit in the cost of use, so companies don't need to worry about hiring someone to maintain the servers or spending time on installation, backups, or application maintenance.

‍

Immediate Availability:

You can use the resources immediately after subscribing and paying for the service.

‍

Greater Security:

Cloud service providers like Amazon, Google, or Microsoft hire highly trained personnel to address issues related to server security. Additionally, the locations where the servers are located have high security for their infrastructure.

‍

Scalability:

Cloud computing also offers scalability, the ability to increase the size of the infrastructure and processing resources more quickly according to the workload. 

‍

- Vertical Scalability (Scale-up):

This involves increasing the capacity of a single server or resource to handle a larger workload.

‍

- Horizontal Scalability (Scale-out):

This involves adding more servers or nodes to a system or application to distribute the workload.

‍

Elasticity:

Cloud computing also provides elasticity, which means that a server's technical capabilities (CPU, RAM, Storage) can vary depending on the demand or traffic.

‍

Disadvantages

‍

Data security and privacy

In the cloud model, companies have to leave their databases managed by a third party, which some companies are unwilling to do.

‍

Limited control over resources

Cloud users or clients have more limitations on infrastructure and need help accessing specific configurations.

‍

Dependence on a third party (service provider)

Under this model, the user/client depends on the service provider. This implies that there may be service availability problems when server updates are made.

‍

Cloud service providers

Currently, there are many cloud service providers, but those that stand out the most for their participation in the global market are Amazon (AWS), Microsoft (Azure), and Google (GCP).

Which platform to choose?

‍

The question of which technology to use is common, and often, the answer is based on market share or popularity. Choosing a popular technology has the advantage of more available documentation and a larger community to help with any questions. However, several factors must be considered to make the best decision, such as costs, availability, supported programming languages and frameworks, and more. To help with this decision, a table of the advantages and disadvantages of the most commonly used platforms is provided below.
