AWS Questions

What is Cloud Computing

It is type of Internet-based computing that provides shared computer processing resources and data to computers and other devices on demand.

It is a model for enabling ubiquitous, on-demand access to shared pool of configurable computing resources (e.g., computer networks, servers, storage, applications and services) provisioned minimal management effort.

This relies on sharing of resources to achieve coherence and economy of scale, similar to a utility (like the electricity grid over an electricity network.)

Compute forms the nucleus of creating and executing business.

AWS provides several compute products that allows to deploy, run, and scale applications as virtual servers, code, or containers.

AWS Compute Covers

  • Simple websites and applications on one or a few servers
  • Control and manage cluster or server level functions such as deployment and scaling
  • Manage stateful or stateless applications packaged as Docker containers
  • Stateless, event-initiated applications that require fast response times

AWS Compute Offerings different Compute services offered by AWS.

  • Amazon EC2 – Virtual Servers in the Cloud
  • Amazon EC2 Container Service – Run and Manage Docker Containers
  • AWS Lambda – Run Code in Response to Events
  • Amazon EC2 Container Registry – Store and Retrieve Docker Images
  • Amazon Lightsail – Launch and Manage Virtual Private Servers
  • Amazon VPC – Isolated Cloud Resources
  • AWS Batch – Run Batch Jobs at Any Scale
  • AWS Elastic Beanstalk – Run and Manage Web Apps
  • Auto Scaling – Automatic Elasticity
AWS Architecture

What is Software as a Service (SaaS)

  • Capability to run applications on a cloud infrastructure.
  • Applications are accessible from several client devices via either a thin client interface, like a web browser e.g., web-based email
  • Interplay between outside world and organization. e.g., email newsletter campaign software
  • Software for a short term requirement. e.g., collaboration software for particular project
  • “Vanilla” offerings where the solution is not differentiated.
  • Consumer does not control or manage the underlying cloud infrastructure, which includes servers, network, operating systems and storage.
  • SaaS is not suitable in scenarios where the application
  • SaaS processes quick real time data.
Software as a Service SAAS


SaaS has a regulation or legislation that does not allow data being hosted externally. Existing on-premise solution that satisfies all of the requirements of organization.

What is Platform as a Service (PaaS)?

Computing platform that permits creating web applications effortlessly, fast, with no complexity of buying or maintaining the infrastructure and software.

  • Services to develop and test applications, as well as deploy, host and maintain applications in the similar integrated development environment.
  • Ability to deploy on cloud infrastructure with the help of programming languages, services, libraries, and tools.
  • Built in scalability of deployed software with failover and load balancing.
  • Integration with databases and web services through common standards.

PaaS is not suitable in scenarios where the application –

  • requires to be more portable with respect to where it is hosted.
  • performance needs customization of the underlying software and hardware.
  • proprietary approaches or languages would affect the development process.

What is Infrastructure as a Service (IaaS)


Capableness to provide networks, processing, storage, and other fundamental computing resources, and ability to deploy, run arbitrary software that can include operating systems and applications. Here, the consumer is incapable of controlling or managing the underlying cloud infrastructure.

  • Resources are distributed as a service and enables dynamic scaling
  • Utility pricing model
  • Multiple users on one hardware Applicability-
  • New organizations with less capital could invest in hardware easily
  • Organizations growing rapidly
  • Pressure on the organization to restrict capital expenditure and to migrate to operating expenditure
  • IaaS is not suitable in cases where strict regulatory compliance is followed
  • very high level of performance is required.
