Affinity Groups vs Availability Set
Affinity Groups: verschiedene Resources physikalisch nahe beieinander (geringe Latenzen) - obsolet seit 2012 da selbe Performance wenn Resources in einer Region
Availability Set für IAS (bei PAS Standard): physikalische Trennung (fault domain und update domain) in verschiedene Racks
Classic Portal vs Preview
Classic: only ASM
Preview: ARM - Namespace enthält RM in cmsLets
Name Azure Powershell modules

standard (HDD - zahlen nur für belegten platz)
Storage pool
data discs zusammenpacken, darauf StorageSpace definieren
CloudServices IAAS vs PAAS
IAAS: automatisches Networking im ASM (Vnet wird automatisch mit erzeugt) - nur V1
PAAS: Web und Workerrole compute

A1
VM Size v2?
does not mean ARM - only depending on processor families

Storage account performance - which options?
Standard storage accounts are backed by magnetic drives and provide the lowest cost per GB. They’re best for applications that require bulk storage or where data is accessed infrequently. Premium storage accounts are backed by solid state drives and offer consistent, low-latency performance. They can only be used with Azure virtual machine disks, and are best for I/O-intensive applications, like databases. Additionally, virtual machines that use Premium storage for all disks qualify for a 99.9% SLA, even when running outside of an availability set. This setting can’t be changed after the storage account is created.
