What are 4 of the fundamental services that Cloud Providers provide?
CANS
Compute power - such as Linux servers or web applications
Analytics - such as visualizing telemetry and performance data
Networking - such as secure connections between the cloud provider and your
company
Storage - such as files and databases
Advantages/Benefits of the Cloud
High availability: Your cloud-based applications can provide a seamless user
experience with no apparent downtime-even when things go wrong-depending on the
service-level agreement that you choose.
Scalability: Applications can be scaled in the cloud in a couple of different ways:
Vertically: Additional computing capacity is available by adding RAM or CPUs to a
virtual machine.
Scale out - Horizontally: Computing capacity can be increased by adding instances of a
resource; for instance, adding virtual machines in your configuration.
,Elasticity: Cloud-based applications can be configured to take advantage of
auto-scaling, wherein your applications will always have the needed resources.
Agility: Application changing requirements can quickly deploy and configure
cloud-based resources.
Geo-distribution Applications and data can be deployed to regional datacenters around
the globe, so your customers always have the best performance in their region.
Disaster recovery By taking advantage of cloud-based backup services, data
replication, and geo-distribution, you can deploy your applications with the confidence
that comes from knowing that your data is safe in the event that disaster should occur.
Azure benefits
Innovate with confidence: Nonstop innovation from Microsoft is so you can develop
today and your product vision for tomorrow.
Build on your terms: You have choices. With a commitment to open source, and support
for all languages and frameworks, build how you want and deploy where you want to.
Seamlessly operate hybrid: On-premises, in the cloud, and at the edge--we'll meet you
where you are. Integrate and manage your environments with tools and services
designed for a hybrid cloud solution.
Trust your cloud: Get security from the ground up, backed by a team of experts, and
proactive compliance trusted by enterprises, governments, and startups.
What are typical Choices for Compute Power?
VACS
,Virtual Machines: Software emulations of physical computers
Azure App Service: This represents the PaaS offering in Azure for hosting
enterprise-grade web-oriented applications.
Containers are a consistent, isolated runtime environment for an application. They're
similar to VMs, except without the need for a guest OS. Instead of using a guest OS, the
application and all its dependencies are packaged into a "container," and then a shared
runtime environment is leveraged to execute the app. This enables the container to boot
up in mere seconds because there is no OS to boot and initialize. You literally just need
the app to start.
Serverless computing is allowing you to run application code without having to create,
configure, or manage a server. It was a concept based on your application, which would
break down into discrete functions that would automatically execute when triggered by
some action. That's great for automated tasks: You could create a serverless process
that sends an automatic email confirmation after a customer has purchased something
online.
Basic difference between VMs and Containers
Containers do not require a host OS and are smaller, hence more resource-efficient
than VMs
What's the most significant advantage of Serverless Computing over VMs or
Containers?
The serverless model is different from both the VMs and containers in that you pay only
for the computing time each function uses while it's running. The VMs and containers
are billed even when they are running, and their resident applications are idle for some
time.
What are four major subjects to know for the fundamentals exam?
CASC
, * Cloud Concepts
* Azure Pricing and Support
* Security, Privacy, Compliance and Trust
* Core Azure Services
Can you have several subscriptions at the same time?
Yup
Does it make any sense to have multiple subscriptions?
Yes. Some companies do this for billing purposes; they get separate billing and invoicing
reports. Or for separating Production from development subscriptions.
Who owns the azure subscription?
The person creating the subscription
What are the purchasing options for Azure products and services?
WEC
Web Direct
Enterprise
Cloud Solution Provider
Enterprise Agreement
An agreement to buy a pre-determined quantity of Azure Services.
Savings of 15-45% percent with respect to Web Direct users
When do you qualify for an Enterprise agreement?
As a private business you have to have 500 users and devices. As a public organization
you must have at least 250 users and devices
