About Me:

Hey Folks! Am Vishwa, DevOps and OpenSource Enthusiast. Currently am doing LearnInPublic and BuildInPublic where I'll be documenting my entire journey on LinkedIn and Twitter to be accountable and to connect with many like-minded people to seek knowledge from them and help each other. Here, In this series, I'll delve deeper into Cloud computing, with a specific focus on AWS. This journey enables effortless learning and experimentation. My goal is to simplify complex concepts for all. Let's get into Part 1 of the series.

What is the Cloud?

- Put simply, the Cloud resembles a bank of invisible servers, empowering users to access resources remotely. Despite its hidden nature, its potential for seamless resource utilization remains unparalleled.

- The cloud refers to a distributed network of servers, each serving a specific purpose, interconnected globally to function as a unified system, despite not being a physical entity itself

Why use the Cloud?

- Embracing cloud technology has enabled numerous businesses and organizations to significantly cut costs, fostering a more efficient and economical operational framework.

- Example: Imagine a small e-commerce business that used to manage its on-site servers to host their website, store customer data, and process online transactions. This required a significant upfront investment in hardware and ongoing maintenance costs. By transitioning to cloud services like Amazon Web Services (AWS), they no longer need to maintain their physical servers. They can now scale their computing resources up or down as needed, paying only for what they use. This shift to the cloud not only saved the business money on hardware and maintenance but also allowed them to focus more on growing their online store and improving the customer experience.

Benefits of using the Cloud:

- Businesses can avoid significant upfront hardware costs and instead pay for what they use on a subscription basis.

- Cloud services can easily scale up or down based on the demands of the business, allowing for flexibility in resource allocation.

- Users can access data and applications from any location with an internet connection, enhancing collaboration and productivity.

- Cloud computing offers reliable data backup and recovery solutions, ensuring that critical data is protected in the event of a disaster.

Types of Cloud:

- The cloud can be categorized into three main types: Public cloud, Private cloud, and Hybrid cloud.

1. Public cloud:

- In the public cloud, Cloud resources and services are managed by a third-party cloud service provider, for example, Amazon Web Services (AWS).

- These resources are accessible to the general public or multiple organizations, allowing users to manage and utilize them through the Internet.

- Public clouds are cost-effective and scalable, making them suitable for a wide range of applications and services.

2. Private cloud:

- A private cloud is dedicated to a single organization and is typically hosted on-premises.

- Private clouds are often used by large enterprises, government agencies, and industries with strict regulatory requirements.

- The disadvantage of using a Private cloud is Maintaining, setting up, and providing support is more costly and time-consuming compared to deploying on a public cloud service. it's an investment that needs continuous support and maintenance

3. Hybrid cloud:

- By seamlessly integrating features of both public and private clouds, a hybrid cloud solution facilitates the seamless sharing of data and applications, enabling businesses to get the best of both worlds for enhanced efficiency and flexibility.

- Organizations use a hybrid cloud to ensure the security of sensitive data within a private cloud, while simultaneously taking advantage of the scalability and cost-efficiency of the public cloud for other essential services.

- This type of cloud offers flexibility and is useful for businesses looking to optimize their IT infrastructure.

Why public cloud is so popular?

- The primary benefit is eliminating the need for maintenance.

- Helps save costs by eliminating the need for additional investments in hardware.

Types of Cloud services:

- There are three primary services infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS).

1. Infrastructure as a Service (IaaS):

- IaaS enables users to access virtualized computing resources via the internet, providing the option to rent virtual machines, storage, and networking infrastructure based on a pay-as-you-go model. This offers businesses the opportunity to bypass the expenses and complexities associated with owning and handling physical hardware.

- Example is Amazon Web Services (AWS).

2. Platform as a service (PaaS):

- PaaS simplifies the app development process by providing a comprehensive platform for developers to build, deploy, and manage applications, freeing them from the complexities of underlying infrastructure and server maintenance. This allows them to direct their energy towards creating innovative software solutions and delivering enhanced user experiences.

- Example is AWS Elastic Beanstalk (AWS EBN).

3. Software as a service (SaaS):

- SaaS offers software applications over the internet through a subscription model, removing the necessity for users to install and manage the software on their own devices. This approach ensures effortless access to applications and allows for seamless updates and maintenance by the service provider.

- Example is Netflix.

How AWS is better than others?

- They have secured their top position in the cloud industry by having a longer tenure in the field compared to their competitors.

- The major advantage is they have more than 200 services.
