Core Azure Concepts Flashcards
What is cloud computing?
Delivery of computing services over the internet (cloud)
Give examples of cloud computing services
Servers, storage, databases, networking, software, analytics, and intelligence

What are the benefits of cloud computing?
Faster innovation, flexible resources, and economies of scale
Why is cloud computing typically cheaper to use?
Pay-as-you-go pricing model which helps:
- Lower your operating costs.
- Run your infrastructure more efficiently.
- Scale as your business needs change.
Are renting compute power and storage from someone else’s datacenter.
MS takes care of maintaining the underlying infrastructure for you.
So can focus on toughest business challenges and bring cutting-edge solutions to users
Why move to the cloud?
Cloud helps you move faster and innovate in ways that were once nearly impossible
Two important trends:
- Teams deliver new features to their users at record speeds.
- Users expect an increasingly rich and immersive experience with their devices and with software.
Cloud provides on-demand access to:
- A nearly limitless pool of raw compute, storage, and networking components.
- Speech recognition and other cognitive services that help make your application stand out from the crowd.
- Analytics services that deliver telemetry data from your software and devices.
What is Azure?
Continually expanding set of cloud services
Gives you the freedom to build, manage, and deploy applications on a massive global network using your favorite tools and frameworks
What is Azure Marketplace?
Connects users with Microsoft partners, independent software vendors, and startups that are offering their solutions and services, which are optimized to run on Azure.

High availability
Depending on the service-level agreement (SLA) that you choose, your cloud-based apps can provide a continuous user experience with no apparent downtime, even when things go wrong.
Scalability
Scale vertically to increase compute capacity by adding RAM or CPUs to a virtual machine.
Scaling horizontally increases compute capacity by adding instances of resources, such as adding VMs to the configuration.
Elasticity
You can configure cloud-based apps to take advantage of autoscaling, so your apps always have the resources they need.
