Azure Redis Tutorial

Introduction to Azure Redis

Azure Redis Cache is a fully managed, in-memory cache service that provides high throughput and low-latency data access. It is based on the popular open-source Redis software and is used to improve the performance and scalability of applications by storing frequently accessed data in-memory.

Setting Up Azure Redis Cache

To get started with Azure Redis Cache, follow these steps:

1. Log in to the Azure Portal.
2. Click on "Create a resource" and search for "Azure Cache for Redis".
3. Click "Create" and fill in the necessary details:
   • Subscription: Select your Azure subscription.
   • Resource group: Choose an existing resource group or create a new one.
   • DNS name: Enter a globally unique name for your Redis instance.
   • Location: Select the region where you want to deploy your Redis instance.
   • Pricing tier: Choose the appropriate pricing tier based on your requirements.
4. Click "Review + create" and then "Create" to provision the Redis instance.

Connecting to Azure Redis Cache

Once your Redis instance is provisioned, you can connect to it using various clients. Below is an example using the redis-cli tool:

sudo apt-get install redis-tools

redis-cli -h your-redis-name.redis.cache.windows.net -p 6379 -a your-access-key

Using Azure Redis Cache

Once connected, you can start using Redis commands to interact with the cache. Here are some common commands:

SET mykey "Hello, Azure Redis!"

GET mykey

DEL mykey

Monitoring Azure Redis Cache

Azure provides built-in monitoring and alerting features to help you keep track of your Redis instance's performance and health. Navigate to your Redis instance in the Azure Portal and click on "Monitoring" to view metrics such as:

• Cache hits and misses
• Memory usage
• CPU usage
• Network bandwidth

Scaling Azure Redis Cache

As your application grows, you might need to scale your Redis instance. Azure Redis Cache supports scaling up or down to different pricing tiers. To scale your instance:

1. Navigate to your Redis instance in the Azure Portal.
2. Click on "Scale" in the left-hand menu.
3. Select the new pricing tier and click "Select".
4. Click "Save" to apply the changes.
