Why Cloud services?
Cloud Computing
Wat is Cloud Computing?
“the delivery of computing services—servers, storage, databases, networking,
software, analytics, intelligence and more—over the internet (the cloud), enabling faster
innovation, flexible resources, and economies of scale”
Hoe heet een bedrijf dat cloud-services levert?
Cloud provider
Waar is een cloud-provider verantwoordelijk voor?
De fysieke hardware en het up-to-date houden ervan
Welke services levert een cloud-provider?
Compute power (bijv. linux, web-applications)
Storage (files en databases)
Network (scure connections between cloud provider and your company)
Analytics (visualizing telemetry and performance data)
Wat is het doel van cloud computing services?
to make running a business easier and more efficient
Wat is een VM?
Virtual Machine: an emulation of a computer where you don’t have to buy hardware or
install the OS.
Wat is een container?
a consistent, isolated execution environment for acpplications. Similar to VM’s except
they don’t require a guest operating system.
The application and all of its dependencies is packaged into a container and run in a
standard runtime environment.
Multiple containers can be run on a single machine.
Wat is het voordeel van een container?
- Start up in just a few seconds, because there is no OS to boot or initialize.
- Portability of containers allow them to be moved between environments and be
deployed in multiple environments, either on-premise or in the cloud, often without
changes to the application
Wat is Serverless computing?
Lets you run application code without creating, configuring or maintaining a server.
Wat is de achterliggende gedachte bij Serverless computing?
Your application is broken into separate functions that run when triggered by some
action
Waar is serverless computing met name geschikt voor?
Automated tasks. Example send email-confirmation after customer makes online
purchase.
Waarin verschilt serverless computing t.o.v. VM’s en containers?
you only pay for the processing time used by each function as it executes, while VM’s
and containers are charges while they’re running, even when idle.
Wat is een voordeel van serverless computing t.o.v. VM’s en containers?
you can test and update them seperately. They launch in microseconds. The fastest
, option for deployment.
Wat is een voordeel van cloud-based data storage?
scale to meet your needs.
Key cloud concepts and benefits
Noem karakteristieken en overwegingen van cloud-services?
- High availability
- Scalability
- Elasticity
- Agility
- Fault tolerance
- Disaster recovery
- Global reach
- Customer latency capabilities
- Predictive cost considerations
- Technical skill requirements and considerations
- Increased productivity
- Security
Wat is High availability?
ability to keep services up and running for long periods of time, with very little
downtime, depending on the service in question
Wat is scalability?
Ability to increase or decrease resources for any given workload.
Scaling out: add additional resources to service a workload
Scaling up: add additional capabilities to manage an increase in demand to the
existing resource
Scalability doesn’t have to be done automatically.
Wat is Elasticity?
Automatically or dynamically increase or decrease resources as needed.
Verschil met scalability is dat elasticity automatisch gebeurt.
Wat is Agility?
Snel reageren. Quickly allocate and deallocate resources. No manual intervention in
provisioning or deprovisioning services.
Wat is Fault tolerance?
remain up and running in the event of a component or service no longer functioning.
Typically redundancy is buil into close services architectures.
Wat is disaster recovery?
Recover from an event which has taken down a clue service.
Wat is global reach?
Reach audiences around the globe.
Wat is customer latency capabilities?
Address slowness experienced by a customer bu deploying resources in datacenters
around the world, so close(r) to the customer.
Wat is predictive cost considerations?
to predict what costs a user incurs for a particular cloud service.
Welke technische skills en overwegingen zijn te maken bij het gebruiken van cloud-
services?
a user can be expert in the application without having to need skills to build and
