What is AWS cloud. Amazon Web Services (AWS) is a bundled remote computing service that provides cloud computing infrastructure over the Internet with storage, bandwidth and customized support for application programming interfaces (API).
Launched in 2006, AWS is provided by cloud solution concept pioneer Amazon Inc. Amazon’s internal IT resource management built AWS, which expanded and grew into an innovative and cost-effective cloud solution provider.What is AWS cloud
Amazon Web Services provides services from dozens of data centers spread across availability zones (AZ’s) in regions across the world. An AZ represents a location that typically contains multiple physical data centers, while a region is a collection of AZ’s in geographic proximity connected by low-latency network links. An AWS customer can spin up virtual machines (V Ms) and replicate data in different AZ’s to achieve a highly reliable infrastructure that is resistant to failures of individual servers or an entire data center.
What is Cloud Computing
Cloud computing is an internet-based computing service in which large groups of remote servers are networked to allow centralized data storage, and online access to computer services or resources.
Using cloud computing, organizations can use shared computing and storage resources rather than building, operating, and improving infrastructure on their own.
Cloud computing is a model that enables the following features.
Users can provision and release resources on-demand.
Resources can be scaled up or down automatically, depending on the load.
Resources are accessible over a network with proper security.
Cloud service providers can enable a pay-as-you-go model, where customers are charged based on the type of resources and per usage.
Cloud Service Models
IaaS stands for Infrastructure as a Service. It provides users with the capability to provision processing, storage, and network connectivity on demand. Using this service model, the customers can develop their own applications on these resources.
PaaS stands for Platform as a Service. Here, the service provider provides various services like databases, queues, workflow engines, e-mails, etc. to their customers. The customer can then use these components for building their own applications. The services, availability of resources and data backup are handled by the service provider that helps the customers to focus more on their application’s functionality.
SaaS stands for Software as a Service. As the name suggests, here the third-party providers provide end-user applications to their customers with some administrative capability at the application level, such as the ability to create and manage their users. Also some level of customizability is possible such as the customers can use their own corporate logos, colors, etc.
