A

Ensures there is no charge once credits are used

39
Q

Spending limits are useful for Dev teams exploring new solution architectures, these are not the same as Subscription, Service or Resource Group limits or quotas, what are they designed to do, and what will happen once all credits are used

A

Spending limits prevent exhausting credit on account within a billing period.
Once credits are used up, services deployed will turn off for the rest of the billing period (will be turned on next period if sufficient credits)

How and against what can reserved instances be purchased

A

Purchase via Azure portal for both Windows and Linux

47
Q

Some locations and regions cost more than others, it is possible to use lower cost regions for some services however what should you be aware of when doing this from purely a cost perspective

A

Some resources are billed on outgoing network bandwidth (egress) so you should provision connected resources that are bandwidth metered in same region

48
Q

How can you keep up to date and switch to offers providing cost savings

A

Check Azure updates page for info on products/services/features + Roadmap of announcemen

49
Q

What is Right Sizing a VM

A

Right size is the process of resizing a VM to the proper size

50
Q

A

Not only changing to a smaller size but also to another series.

51
Q

What does resizing require and how long will it take

A

Stop, Resize, Start

May take minutes or seconds so you should plan for outage or traffic shift

52
Q

When can deallocating a VM be used to save costs

Shut it down to save infrastructure and licence costs

54
Q

Natural migration to cloud starts with IaaS then goes on to…

Q

Where does PaaS typically offer savings

Resource and operational costs

56
Q

Migration to PaaS can be easy or difficult, can you give examples

A

Easy: SQL > Azure SQL DB
Difficult: Multi-Tier App to container or serverless

57
Q

True or False: PaaS is usually a quick journey so is good for quick Cost savings

A

False: PaaS is typically a longer journey and thus not so useful for quick cost savings

58
Q

79
Q

How can Enterprise Agreement customers, with SQL licences free’d up due to cloud migrations save money.

A

Save money on Azure VM cost by utilising a BYOL Instance from the Azure Market place.
You have always been able to manually do this but with these MS Certified images it is even easier

80
Q

How can you save money on you dev and test SQL workloads on a VM in Azure

A

Utilising SQL Developer Edition, it is free with the same features as Enterprise.
Look for SQL Developer Edition in the Marketplace

81
Q

How can constrained instance sizes help for Database workloads

A

Because products like SQL and oracle are licensed per CPU, customers can reduce licensing costs by up to 75% and still maintain the high performance their DB requires.

82
Q

What are constrained instances (for database workloads)

A

Customers may have high requirements for memory, storage and IO Bandwidth, but often have lesser requirements for CPU.

Due to popular request MS have made popular VM sizes available with either 1/2 or 1/4 the vCPU count, but maintaining the same Memory, Storage and IO bandwidth

83
Q

Which Popular VM sizes have MS made available in constrained VM sizes

A

DS, ES, GS, MS
