- 18. Azure Deployment Models • CLASSIC MODEL (ASM) • AZURE RESOURCE MANAGER (ARM) • ARM VS CLASSIC MODEL
- 19. Classic Model - ASM Azure originally provided only the classic deployment model Each resource exists independently and cannot be grouped Manage resources in a coordinated approach Deploy/Delete all the resources in the correct order Tags are not supported
- 20. Azure Resource Manager (ARM) Resource manager provides template based repeatable deployment model for all Azure resources Behaves as control planes for Azure services Within Resource Manager, resources can be grouped, deployed, managed and monitored as a resource group Faster than classic Azure Service Management (ASM) model Reusable/linkable JSON template Mark one resource dependable on another Supports tagging of resources Microsoft recommends all the new Azure resources should be created using ARM
- 21. Resource Groups Under ARM, all the resources are grouped into a Resource Group All of the resources in a resource group share the same lifecycle A resource can only be assigned to one group at a time A resource can be added to or removed from a resource group at any time. Most types of resource can be moved to a different resource group at any time The resources in a resource group can be in different regions You can use a resource group to control access for the resources therein
- 22. Resource Providers Offers a set of resources and operations for working with an Azure service Microsoft.AppService Microsoft.AzureActiveDirectory Microsoft.Compute Microsoft.DocumentDB Microsoft.EventHub Microsoft.Sql Microsoft.Storage ….
- 23. Role based Access Control Fine-grained control over the operations and scope with which a user can perform an action Permissions at resource level against Co-administrators Supported roles- Owner Reader SQL DB contributor SQL Security Manager Storage Account Contributor VM Contributor Custom Roles Supports Service Principals

- 36. Azure Storage • STORAGE ACCOUNTS • Blobs • Tables • Queues • Files • DEMO
- 37. Azure Storage - Overview Microsoft-managed service providing durable, scalable, and redundant storage Includes following services- Blob Storage Table Storage Queue Storage File Storage
- 38. Storage Accounts Secure account to give access to Azure Storage services Unique namespace for storage resources Types of storage accounts- General-purpose storage accounts Blob storage accounts 100 storage accounts per subscription Each storage account has 500TB of storage limit
- 39. Shared Access Signatures Provides controlled access to Azure storage resources A shared access signature (SAS) is a token that can be appended to a URL that enables delegated access to a storage resource Anyone who possesses the token can access the resource it points to with the permissions it specifies, for the period of time that it is valid Two types- Service SAS Account SAS
- 40. Redundancy options Protects data and preserves application up-time in the event of transient hardware failures Replication copies data, either within the same data center, or to a second data center Replication Types Locally-redundant storage (LRS) Zone-redundant storage (ZRS) Geo-redundant storage (GRS) Read-access geo-redundant storage (RA-GRS)
- 41. Azure Blob Storage Large amounts of unstructured object data Highly cost-effective and scalable Every blob is organized into a container http://<storage account>.blob.core.windows.net/<container>/<blob> Blob types includes- Block blobs Append blobs Page blobs Useful for storing media files like videos, audios, images Useful for back-up
- 42. Azure Table Storage Microsoft's NoSQL key/attribute store – schema-less design Highly available, massively scalable storage for structured data Collection of entities – where a collection of properties and their values comprise an entity http://<storage account>.table.core.windows.net/<table> Two entities in the same table can contain different collections of properties, and those properties can be of different types An entity always has 3 properties – PartitionKey, RowKey and TimeStamp The combination of PartitionKey and RowKey should always be unique to serve as primary key All entities with same partition key are stored on same storage node RowKey denotes uniqueness within the partition Each entity can have 252 properties or key/value pairs
- 44. Azure Storage Queues Reliable messaging solution for asynchronous communication Supports managing asynchronous tasks and building process workflows A message can be up to 64KB of size http://<storage account>.queue.core.windows.net/<queue> Time-to-live(TTL) for a message can be up to 7 days Maintains all server-side logs for all the transactions against the queue Preferable when queue size grows over 80 GB in size
- 45. Azure File Shares Cloud-based SMB file shares Idle for moving legacy applications to Azure that rely on file shares A virtual machine can mount a file share just as a desktop application mounts a typical SMB share Based on SMB-3, it can be mounted on Windows VM across Azure regions or on-premise Accessible over REST API anywhere Maximum size can be up to 5 TB and each file can be of 1 TB maximum size Multiple VMs can share same Azure File Share

- 47. SQL Database • INTRODUCTION TO SQL DATABASE • SQL SERVER IN A VM • DEMO
- 48. Azure SQL Database - Overview Managed Cloud Database as a Service Based on SQL Server Engine Each database in Azure SQL Database is associated with a logical server Scale on the fly It can be A single database with its own set of resources (DTUs) Part of an elastic pool that shares a set of resources (eDTUs)
- 49. Azure SQL Database – Size Chart
- 50. Azure SQL Database – Elastic Pool Simple, cost-effective solution for managing and scaling multiple databases that have varying and unpredictable usage demands The databases in an elastic pool are on a single Azure SQL Database server and share a set number of resources at a set price Optimizes the price performance for a group of databases within a prescribed budget while delivering performance elasticity for each database. When to consider a pool? Well suited for a large number of databases with low average utilization with relatively infrequent utilization spikes The more the number of databases added to a pool the greater are the savings
- 51. Azure SQL Database On-premise SQL Server database need some re-engineering before migrating from on premise to Azure SQL Database Does not supports Windows Authentication, but supports Azure Active Directory authentication Unsupported features includes – Always On Availaibility Groups, BACKUP, CLR, Database Mirroring, Database Snapshots, SSIS, SSRS, SSAS, etc. Complete list is here Unsupported T-SQL statements includes – HAS_DBACCESS, sp_configure, EXECUTE AS LOGIN, fn_get_sql, etc. Complete list is here T-SQL debugging is not supported Differences with On-premise SQL Server
- 52. Azure SQL Database - Demo
- 53. SQL Server in a VM Useful when SQL Database doesn’t offers the required features Things to consider while opting for SQL server on a VM: Pricing might includes OS license cost, SQL Server license cost You can bring your own licenses Pricing also includes Azure Storage cost which is used for storing VHDs At Least DS2 VM for standard edition At least DS3 VM for Enterprise edition Azure will offer high availability of VM overall but not the SQL Server instance Choose SQL Server in a VM if high level of control is desired Also useful for lift-and-shift database migrations Consider other databases to bring down the costs – MySQL is available on Azure
