Build modern cloud native applications with Kubernetes and OSS databases on Azure Sunitha Muthukrishna Senior Program Manager Microsoft

Speaker Sunitha Muthukrishna, Senior Program Manager Azure Database for PostgreSQL, MySQL & MariaDB @mksuni

Agenda What’s new with Open Source DBs on Azure • What’s is AKS • Top scenarios for AKS • Best practices with using AKS • Deploy a cloud native WordPress application with MySQL • Simple Postgres Deployment • Github Action for Postgres and MySQL • Scale and Manage the cluster and database • Diagnose and Solve experiences

Azure builds upon the core benefits of PostgreSQL and MySQL Global reach Security Scale up Built-in HA Compliance Easy ecosystem integration

Existing deployment options for Postgres and MySQL Hyperscale (Citus) Worry-free PostgreSQL in the cloud with an architecture built to scale out Single Server Enterprise-ready, fully managed community OSS engines

Looking back Security § Azure AD authentication § Customer-managed key encryption § Infrastructure double encryption § Minimum TLS version requirements Performance § Read replicas § Intelligent Performance Manageability § RI for all GA services § Storage auto grow Trusted by companies of all sizes 50 regions

New deployment option : Flexible Server Hyperscale (Citus) Worry-free PostgreSQL in the cloud with an architecture built to scale out Single Server Enterprise-ready, fully managed community OSS engines Azure Arc enabled Postgres Hyperscale NEW Scale out PostgreSQL in environment of your choice Flexible Server (Preview) NEW Maximum control with a simplified developer experience

Introducing Flexible Server (Preview) for Build resilient apps across availability zones Maximum control for your databases Simplified developer experience

When to use Single Server vs. Flexible Server (Preview) Single Server Flexible Server (Preview) Database Version § MySQL 5.7, 8 § Postgres 9.5, 9.6, 10, 11 § MySQL 5.7 § MySQL 8.0 (planned) § Postgres 11, 12 § Postgres 13 (planned) High Availability Built-in HA (Single-AZ) Zone Redundant HA Scheduled Maintenance System scheduled System or custom scheduled Stop/Start P P PITR P P Network Isolation P Private Link P VNET Integration Customer managed keys for Encryption P O (planned) Reserved Instances (RI) P O (planned) Cross region replicas P O (planned) Uptime SLA 99.99% O (planned)

Data Platform Virtual Summit 2020 is a community initiative by DataPlatformGeeks AZURE KUBERNETES SERVICE

Kubernetes on its own is not enough Save time from infrastructure management and roll out updates faster without compromising security Unlock the agility for containerized applications using: • Infrastructure automation that simplifies provisioning, patching, and upgrading • Tools for containerized app development and CI/CD workflows • Services that support security, governance, and identity and access management IDE container support Registry supporting Helm CI/CD Monitoring Microservice debugging Networking Virtual machines Security Governance Identity Source code repository <\> Kubernetes Storage Data Infrastructure automation

Azure Kubernetes Service Enterprise-grade by design Unified management Multi-layer security Hardened security and layers of isolation across compute resources, data, and networking Enterprise support Support from certified Kubernetes experts or an interactive portal experience for faster diagnostics and troubleshooting Consistent configuration and governance across environments Built-in best practices Proactive and actionable recommendations, based on knowledge from thousands of enterprise engagements

Top Scenarios for Kubernetes on Azure with OSS databases

Data Platform Virtual Summit 2020 is a community initiative by DataPlatformGeeks DEPLOY WORDPRESS APP IN AKS + MYSQL FLEXIBLE SERVER

Command to create mysql flexible server Create MySQL flexible database server using these command which uses public access connectivity. Provide an IP address for your client machine to give access. az mysql flexible-server create --public-access

Command to create aks cluster with 4 node count Create an AKS cluster az aks create --name MyAKSCluster --resourcegroup MyResourcegroup –node-count 4 Install Kubectl to connect and manage cluster az aks install-cli Set PATH set PATH=%PATH%;C:\Users\\.azure-kubectl Get Credentials to connect to the cluster az aks get-credentials --name MyAKSCluster --resourcegroup MyResourcegroup

Install Kubernetes manifest file Use the sample WordPress Kubernetes yaml file Docker image used in the demo php-sample-app:wordpress This docker image has custom WordPress installation with custom wp-config.php.

Retry logic for transient faults • An error occurs when you try to open a connection. • An idle connection is dropped on the server side. When you try to issue a command, it can't be executed. • An active connection that currently is executing a command is dropped. protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder) => optionsBuilder.UseNpgsql( "", options => options.EnableRetryOnFailure(maxRetryCount, maxRetryDelay, errorNumbersToAdd));

Connection pooling PostgreSQL or MySQL pod Main app Main app Pgbouncer Connect Connect

Optimize container sizing • Some containers may require large amount of memory • Cron runs memory heavy jobs such as indexer which allocates a few GB of memory • Redis may allocate 4 – 8 GB of memory Resource requests

Data Platform Virtual Summit 2020 is a community initiative by DataPlatformGeeks SCALE AND MANAGE AKS CLUSTER AND FLEXIBLE SERVER

Commands to scale up your cluster and database server Scale the AKS cluster • az aks scale --resource-group myResourcegroup --name myAKSCluster --node-count 1 -- nodepool-name MyPoolname Scale the MySQL database server using these commands. The example below will convert storage size to 512 GB and update the pricing tier to Burstable 2vCore • az mysql flexible-server update --sku-name Standard_B2s --resource-group myResourcegroup –name servername --storage-size 512 Example for PostgreSQL flexible server • az postgres flexible-server update --sku-name Standard_B2s --resource-group myResourcegroup –name servername --storage-size 512

Commands to manage your cluster (Start/Stop) This is in preview (documentation) Install AKS preview CLI # Install the aks-preview extension az extension add --name aks-preview # Update the extension to make sure you have the latest version installed az extension update --name aks-preview Register Start/Stop preview feature az feature register --namespace "Microsoft.ContainerService" --name "StartStopPreview“ Refresh registration Microsoft.ContainerService resource provider az provider register --namespace Microsoft.ContainerService Start and Stop the AKS cluster az aks stop --name myAKSCLuster –resource-group MyResourcegroup az aks start --name myAKSCLuster –resource-group MyResourcegroup

Commands to manage your database server (Start/Stop) Start and Stop the MySQL database server az mysql flexible-server stop --name servername –resource-group MyResourcegroup az mysql flexible-server start --name servername –resource-group MyResourcegroup Start and Stop the PostgreSQL database server az postgres flexible-server stop --name servername –resource-group MyResourcegroup az postgres flexible-server start --name servername –resource-group MyResourcegroup
