What is cloud computing?
Cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the internet (“the cloud”) to offer faster innovation, flexible resources, and economies of scale.
List the types of cloud.
Public cloud
Private cloud
Hybrid cloud
Multi-cloud
What are the top benefits of cloud computing
- Cost. Optimising IT cost by eliminating things like capital expenditure (CapEx)
- Speed. Capacity planning made easy with fast provisioning of cloud services
- Global scale. Ability to scale elastically in the right geographic location
- Productivity. Reduces the time spent in an on-site data Center to spend it on more important business
- Performance. Properly maintained and secure cloud data centres reduce network latency and provide economies of scale.
- Reliability. Backup and data recovery are easier and cheaper on a cloud environment
- Security. Cloud providers offer a broad set of policies, technologies, and controls that strengthen security, protect data, apps, and infrastructure from potential threats.
List the categories of cloud services
- IaaS
- PaaS
- Serverless
- SaaS
What is a public cloud?
Clouds owned and operated by 3rd party cloud service providers which deliver computing services like servers and storage over the internet.
What is a private cloud?
Refers to computing resources used exclusively by a single business or organisation.
What is a hybrid cloud?
Cloud that combines both public and private clouds, bound together by technology that allows data and applications to be shared between them.
What is IaaS?
Is a category or stack of cloud computing where you rent IT infrastructure (servers, vms, storage, networks, os) from a cloud service provider on a pay as you go basis
What is PaaS in full?
Platform as a service
What is PaaS
Refers to cloud computing services that supply an on-demand environment for developing, testing, delivering and managing software applications.
What is SaaS
Software as a service (SaaS) is a method for delivering software applications over the internet, on demand and typically on a subscription basis.
What is serverless computing?
Overlapping with PaaS, serverless computing focuses on building app functionality without spending time continually managing the servers and infrastructure required to do so.
