AWS Cloud Computing
The concept of the client-server model is essential in cloud computing, where multiple clients utilize services from a centralized server. The client interacts with and requests information from the server. Cloud computing, a computing service accessible via the internet, follows a pay-as-you-go model for delivering IT resources. Deployment models in cloud computing include cloud-based, on-premises, and hybrid. Cloud-based deployment allows for the development of new applications or migration of existing ones to the cloud, with varying levels of services. On-premises deployment, also known as private cloud deployment, involves utilizing virtualization and resource management tools within an organization’s data center. Hybrid deployment connects cloud resources with an on-premises infrastructure, often chosen when dealing with sensitive data or government regulations. AWS (Amazon Web Services) offers free and paid cloud courses, enabling individuals to upskill and engage in text and video-based learning experiences.

What is cloud computing? | IBM
Cloud computing refers to the delivery of software applications, development platforms, and computing resources over the internet. There are three primary models of cloud services: SaaS, PaaS, and IaaS.
SaaS, or Software-as-a-Service, involves hosting application software in the cloud, allowing users to access it through a web browser, desktop client, or API integration. Users typically pay a subscription fee based on usage. SaaS is widely used and offers a wide range of software solutions, from industry-specific applications to enterprise software and AI.
PaaS, or Platform-as-a-Service, provides developers with an on-demand platform for running and managing applications. The cloud provider hosts the entire software stack, infrastructure, and development tools, eliminating the need for on-premises maintenance. PaaS often utilizes container technology, allowing developers to package applications with specific operating system services.
IaaS, or Infrastructure-as-a-Service, offers on-demand access to computing resources such as servers, networks, and storage. Users can scale these resources as needed, reducing the need for upfront capital expenditures. IaaS provides users with the most control over computing resources in the cloud and was popular in the early 2010s, although SaaS and PaaS are now growing at a faster rate.
Serverless computing, or Functions-as-a-Service (FaaS), is a cloud computing model that outsources backend infrastructure management tasks to the cloud provider. It allows developers to focus on application code and business logic while the provider handles provisioning, scaling, and patching. Serverless computing runs application code on-demand and automatically scales the supporting infrastructure based on request volume. Customers only pay for resources used during application runtime.
Overall, cloud computing offers cost savings, scalability, and time-to-value benefits. SaaS, PaaS, and IaaS are common models used by organizations, and serverless computing is a subset of serverless architecture that enables developers to execute specific functions in response to events, with automated provisioning and billing based on execution time.

Top 11 benefits of cloud computing
Cloud computing offers numerous benefits for organizations, including high availability, reliability, scalability, elasticity, agility, cost savings, global reach, pre-certified compliance, enhanced security, automation, and environmental sustainability.
High availability is a key advantage of cloud computing, as cloud-based services experience minimal downtime and offer near real-time deployment capabilities. Cloud providers offer service level agreements (SLAs) guaranteeing uptime of 99.95% or higher.
Reliability is ensured through regular system upgrades, updates, patching, and testing by cloud providers. Cloud storage services offer high levels of durability, with promises of up to 99.999999999% reliability.
Scalability in the cloud is effortless, allowing organizations to quickly and easily scale their architecture to meet demand. Additional processing power, virtual CPUs, and throughput can be added within minutes and with a few clicks.
Elasticity is another advantage, enabling organizations to scale their resources up and down as needed. This flexibility eliminates the need for overprovisioning hardware and reduces operational expenses.
Cloud computing enhances agility by freeing developers from the burden of infrastructure management. They can quickly experiment with new software and test changes against various server configurations, saving time and effort.
Cost savings are a significant benefit of cloud computing. Capacity planning becomes more accurate, and organizations avoid upfront costs for software licenses and hardware. Operational expenses are incurred only for the resources used, and the cloud’s economies of scale lead to cost efficiencies.
Global reach is achievable through cloud-based services, with data centers located on multiple continents. Organizations can deploy applications globally and reduce latency by utilizing edge locations for data caching.
Pre-certified compliance is advantageous for highly regulated industries, as major cloud providers offer infrastructure that meets various privacy, security, and regulated standards. Cloud vendors maintain lists of compliance certifications, allowing organizations to run applications in a pre-certified environment.
Enhanced security is provided by cloud vendors through features such as automatic encryption of data in transit and at rest. Built-in tools and monitoring capabilities help organizations ensure compliance and detect noncompliant configurations.
Automation is a fundamental aspect of cloud computing, with APIs available for programmability and resource management. Developers can create, configure, query, and destroy cloud-based resources using SDKs, enabling efficient and automated infrastructure management.
Cloud computing contributes to environmental sustainability by leveraging economies of scale and using resources more efficiently. Cloud providers achieve significant reductions in the number of servers, power consumption, and carbon emissions compared to individual data centers.
In summary, cloud computing offers a wide range of benefits, including high availability, reliability, scalability, elasticity, agility, cost savings, global reach, compliance, security, automation, and environmental sustainability.
