High Availability
The ability to keep services up and running for long periods of time, while experiencing little to no downtime.
Scalability
The ability to increase or decrease resources for a given workload. You can add resources to service a workload (scale out), or add additional capabilities to handle increases in
demand (scale up).
Elasticity
The ability to automatically or dynamically increase or decrease resources as necessary.
Agility
The ability to react quickly. Cloud services can allocate and deallocate resources quickly.
Disaster Recovery
The ability to recover from a cloud service outage. Cloud services disaster recovery should happen quickly through automation.
Predictive Cost
The ability to predict what costs will be incurred for a particular cloud service or offering.
Fault Tolerance
The ability to remain up & running even if a component or service is no longer functioning.
PUBLIC CLOUD
-Owned by the cloud services provider
-Provides resources to multiple organizations
-Most common cloud-type deployment model
-Deep technical knowledge not required to set up
-Usually accessed over the internet via browser
PRIVATE CLOUD
-Owned / operated by organization that uses it
-Created within organization's own datacenter
-Usually accessed securely over private network
-Does not provide access to the public
-Technical knowledge needed to setup & manage
HYBRID CLOUD
-Combines both public and private clouds
-Technical knowledge needed to setup & manage
-Resource deployed across private & public clouds
-The most complex cloud model
-The most flexible cloud model
Infrastructure-as-a-Service
IaaS is the most basic category of cloud computing services. IaaS has no upfront costs and users pay only for what they consume.
Customers are responsible for the purchase, installation, configuration, and management of their own operating systems, middleware, and applications.
Cloud provider maintains underlying cloud infrastructure.
Platform-as-a-Service
PaaS provides an environment for building, testing, and deploying software applications.
Resources are purchased from a cloud service provider on a pay-as-you-go basis and accessed over a secure Internet connection.
There are no upfront costs, and users pay only for what they consume.
Customers are not responsible for managing the server or infrastructure.
Software-as-a-Service
SaaS is software that is centrally hosted and managed for the end customer.
Typically licensed through a monthly or annual subscription.
Common examples are email, calendars, and office tools such as Microsoft Office 365.
No upfront costs. Cloud provider is responsible for the provision, management, and maintenance of the application software.
Common Microsoft Azure Commute Resources:
Azure Functions
Azure Kubernetes Service
Azure App Service
Azure Container Instances
Azure Virtual Machines
Key Azure Network Services
Azure Virtual Network
Key Azure Network Services
Allows Azure resources, like virtual machines, to securely communicate with one other, with the internet, and with on-prem networks.
Azure Load Balancer
Provides a way to scale applications and to create high availability for them. The Load Balancer service supports inbound and outbound scenarios, while providing low latency & high throughput. Typically, you'll use a load balancer to load balance incoming internet traffic & internal traffic across Azure services.
VPN Gateway
Used to send encrypted traffic over the public internet between an Azure Virtual Network and an on-prem network.
Azure Application Gateway
A web traffic load balancer that is used to manage traffic to web apps. Included web application firewall can be used to help protect your web application.
Content Delivery Network
Referred to as a CDN. It's a distributed network of servers that are used to moreefficiently serve web content to users.
THE THREE AZURE DATA CATEGORIES
STRUCTURED DATA vs SEMI-STRUCTURED DATA vs UNSTRUCTURED DATA
Structured:
Structured data is data that sticks to a schema. Can be stored in a database table that consists of rows and columns, and it relies on keys to indicate how one row in a table relates to data in another row in another table.
Referred to as relational data. Structured data is generally easier to enter, query, and analyze because all of the data adheres to the same format.
SEMI-STRUCTURED:
Semi-structured data is less organized than structured data.
The fields of semi-structured data don't neatly fit into tables, rows, and columns.
Isn't stored in a relational format, like structured data is.
Tags are used to make the organization and hierarchy of semistructured data apparent.
Also referred to as non-relational data or NoSQL data.
UNSTRUCTURED
Unstructured data has no specific structure.
Can hold ANY kind of data.
Businesses are turning more and more to unstructured data to drive sales and improve marketing.
Things like PDF documents, JPG images, and video content is considered unstructured data.
THE 5 DIFFERENT Azure Storage Services
- Disk Storage
Disk storage provides disks that VMs, applications, and other services can access and use as needed – much in the same way they would in any typical onprem scenarios.
Disks come in two flavors - managed and unmanaged. Managed disks are managed by Azure, whereas unmanaged disks are managed by the user or customer.
2 Containers (Blobs)
Azure Blob storage is Microsoft's Azurebased object storage solution. It's optimized for storing massive amounts of unstructured data, such as text or binary data.
You would generally choose blog storage in cases where you need to serve images or documents directly to a web browser, or when you will be storing files for distributed access.
3 Azure Files
Azure Files allows organizations to set up highly available network file shares that are accessible via the standard SMB protocol. This allows multiple virtual machines can share the same files with both read and write access – just as they could with any typical on-prem file share.
Data stored in an Azure file share can also be accessed using the REST interface or the storage client libraries.
4 Azure Queues
The Azure Queue Service is used to store and retrieve messages. Queue messages can be up to 64 KB in size, and a queue can contain millions of messages.
Queues are normally used to store lists of messages that need to be processed asynchronously.
5 Azure Tables
Azure Table storage is a NoSQL datastore designed to store large amounts of structured data. It accepts authenticated calls from both inside and outside the Azure cloud.
Organizations will often use Azure Table storage when they need to store TBs of structured datasets that don't require complex joins, foreign keys, or stored procedures and can be denormalized for fast access.
