Redis Cloud is a fully-managed cloud service for hosting and running your Redis dataset in a highly-available and scalable manner, with predictable and stable top performance. You can quickly and easily get your apps up and running with Redis Cloud through its App Service add-on at Azure Store, just tell us how much memory you need and get started instantly with your first Redis database.
Redis Cloud offers true high-availability with its in-memory dataset replication and instant auto-failover mechanism, combined with its fast storage engine. You can easily import an existing dataset to any of your Redis Cloud databases, from your S3 account or from any other Redis server. Daily backups are performed automatically and in addition, you can backup your dataset manually at any given time. The service guarantees high performance, as if you were running the strongest cloud instances.
Choose the Redis Cloud add-on from the Azure Store's App Service catalog, select your plan and set a unique name for your resource, approve your purchase and you're done.
On your Azure add-ons console, wait for your Redis Cloud service to be started. Then, simply click on your service's Connection Info and get your Redis Cloud host, port and password.
The redis-rb is a very stable and mature Redis client and is probably the easiest way to access Redis from Ruby.
Install redis-rb:
sudo gem install redis
For Rails 2.3.3 up to Rails 3.0, update the config/environment.rb to include the redis gem:
config.gem 'redis'
For Rails 3.0 and above, update the Gemfile:
gem 'redis'
And then install the gem via Bundler:
bundle install
Lastly, create a new redis.rb initializer in config/initializers/ and add the following code snippet:
$redis = Redis.new(:host => "<your_redis_cloud_host>", :port => <your_redis_cloud_port>, :password => "<your_redis_cloud_password>")
Add this code snippet to your configure block:
configure do
. . .
require 'redis'
$redis = Redis.new(:host => "<your_redis_cloud_host>", :port => <your_redis_cloud_port>, :password => "<your_redis_cloud_password>")
. . .
end
No special setup is required when using Redis Cloud with a Unicorn server. For Rails apps on Unicorn, follow the instructions in the Configuring Redis from Rails section and for Sinatra apps on Unicorn see Configuring Redis on Sinatra section.
$redis.set("foo", "bar")
# => "OK"
$redis.get("foo")
# => "bar"
Jedis is a blazingly small, sane and easy to use Redis java client. You can download the latest build from github or use it as a maven dependency:
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>2.0.0</version>
<type>jar</type>
<scope>compile</scope>
</dependency>
Configure the connection to your Redis Cloud service using your Connection Info and the following code snippet:
JedisPool pool = new JedisPool(new JedisPoolConfig(),
"<your_redis_cloud_host>",
<your_redis_cloud_port>,
Protocol.DEFAULT_TIMEOUT,
"<your_redis_cloud_password>");
jedis jedis = pool.getResource();
jedis.set("foo", "bar");
String value = jedis.get("foo");
// return the instance to the pool when you're done
pool.returnResource(jedis);
(example taken from Jedis docs).
redis-py is the most commonly-used client for accessing Redis from Python.
Use pip to install it:
sudo pip install redis
Configure the connection to your Redis Cloud service using your Connection Info and the following code snippet:
import os
import urlparse
import redis
import json
r = redis.Redis(host="<your_redis_cloud_host>", port=<your_redis_cloud_port>, password="<your_redis_cloud_password>")
>>> r.set('foo', 'bar')
True
>>> r.get('foo')
'bar'
Redis can be used as the back-end cache for Django. To do so, install django-redis-cache:
pip install django-redis-cache
Next, configure your CACHES in the settings.py file:
import os
import urlparse
import json
CACHES = {
'default': {
'BACKEND': 'redis_cache.RedisCache',
'LOCATION': '%s:%s' % ("<your_redis_cloud_host>", <your_redis_cloud_port>),
'OPTIONS': {
'PASSWORD': "<your_redis_cloud_password>",
'DB': 0,
}
}
}
from django.core.cache import cache
cache.set("foo", "bar")
print cache.get("foo")
Predis is a flexible and feature-complete PHP client library for Redis.
Instructions for installing the Predis library can be found here.
Loading the library to your project should be straightforward:
<?php
// prepend a base path if Predis is not present in your "include_path".
require 'Predis/Autoloader.php';
Predis\Autoloader::register();
Configure connection to your Redis Cloud service using your Connection Info and the following code snippet:
$redis = new Predis\Client(array(
'host' => '<your_redis_cloud_host>',
'port' => <your_redis_cloud_port>,
'password' => '<your_redis_cloud_password>'
));
$redis->set('foo', 'bar');
$value = $redis->get('foo');
node_redis is a complete Redis client for node.js.
You can install it with:
npm install redis
Configure the connection to your Redis Cloud service using your Connection Info and the following code snippet:
var redis = require('redis');
var client = redis.createClient(<your_redis_cloud_port>, "<your_redis_cloud_host>", {no_ready_check: true});
client.auth("<your_redis_cloud_password>");
###Testing (Node.js)
client.set('foo', 'bar');
client.get('foo', function (err, reply) {
console.log(reply.toString()); // Will print `bar`
});
