aws redis remote access

How do I access AWS Redis?

Sign in to the AWS Management Console and open the ElastiCache console at https://console.aws.amazon.com/elasticache/ . From the navigation pane, choose Redis clusters. The clusters screen will appear with a list of Redis (cluster mode disabled) and Redis (cluster mode enabled) clusters.

What is the difference between Redis and ElastiCache?

ElastiCache supports Memcached and Redis. On the other hand, Redis is detailed as "An in-memory database that persists on disk". Redis is an open source, BSD licensed, advanced key-value store. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets and sorted sets.

Is Redis free AWS?

Amazon ElastiCache for Redis ElastiCache for Redis is available for free trial with the AWS Free Tier.

Does ElastiCache require VPC?

To create an ElastiCache cluster within an Amazon VPC, your Amazon VPC must meet the following requirements: The Amazon VPC must allow nondedicated Amazon EC2 instances. You cannot use ElastiCache in an Amazon VPC that is configured for dedicated instance tenancy.

What is faster than Redis?

Redis vs MongoDB Speed This means that as the data stored in the database gets larger and larger, MongoDB is able to operate much faster than Redis. Redis is only significantly faster when the stored data is relatively small in size.

Is ElastiCache actually Redis?

ElastiCache for Redis combines the speed, simplicity, and versatility of open-source Redis with manageability, security, and scalability from Amazon to power the most demanding real-time applications in Gaming, Ad-Tech, E-Commerce, Healthcare, Financial Services, and IoT.

Can I use Redis as database?

Redis can be used as a distributed cache, which is probably its most common and popular use case, as a NoSQL Database and as a Message broker (pub\sub mode, similar to Kafka or RabbitMQ).

Is Elasticsearch faster than Redis?

A simple Wikipedia use case – We found RediSearch faster by 58% on indexing and x4 faster when performing two-word searches on the indexed dataset. A more advanced multi-tenant use case – RediSearch created 50k indices in just 201 seconds while Elasticsearch crashed after 921 indices were created.

Is Redis faster than Memcached?

Redis uses a single core and shows better performance than Memcached in storing small datasets when measured in terms of cores. Memcached implements a multi-threaded architecture by utilizing multiple cores. Therefore, for storing larger datasets, Memcached can perform better than Redis.

Can ElastiCache be public?

Amazon ElastiCache Cluster, inside or outside a VPC, is never allowed to be accessed from the Internet.

How do I connect VPC to ElastiCache?

Sign in to the AWS Management Console and open the Amazon VPC console at https://console.aws.amazon.com/vpc .In the navigation pane, choose Security Groups.Select or create a security group that you will use for your Cluster instances. ... From Type choose Custom TCP Rule. ... Choose Save when you finish.

What is AWS Redis cluster?

A cluster is a collection of one or more cache nodes, all of which run an instance of the Redis cache engine software. When you create a cluster, you specify the engine and version for all of the nodes to use. The following diagram illustrates a typical Redis cluster.

How do you use Redis in ElastiCache?

Does ElastiCache support Redis modules?

Note: Amazon ElastiCache for Redis doesn't provide support for Redis modules.

What is the difference between Redis and Memcached?

When storing data, Redis stores data as specific data types, whereas Memcached only stores data as strings. Because of this, Redis can change data in place without having to re-upload the entire data value. This reduces network overhead.

What is the difference between Elasticsearch and ElastiCache?

Amazon ElastiCache belongs to "Managed Memcache" category of the tech stack, while Elasticsearch can be primarily classified under "Search as a Service". Some of the features offered by Amazon ElastiCache are: Support for two engines: Memcached and Redis. Ease of management via the AWS Management Console.

Solution overview

To demonstrate this solution, we implement the following high-level steps:

Implementation in AWS Cloud Development Kit

We present the solution to you in the AWS Cloud Development Kit (AWS CDK), which is a software development framework that defines infrastructure through object-oriented programming languages—in our case, Typescript. You can clone the code from the GitHub repo.

Deploy the solution

The infrastructure for this solution is implemented in AWS CDK in Typescript and can be cloned from the GitHub repository.

Cost of running the solution

The solution to associate an IAM entity with an ElastiCache RBAC user requires deploying a sample ElastiCache cluster, storing secrets in Secrets Manager, and defining an ElastiCache RBAC user and user group. To run this solution in us-east-1, you can expect the following costs. Please note that costs vary by region.

Clean up the resources

To delete all resources from your account, including the VPC, call the following command from the project root folder:

Conclusion

Although fine-grained access is now possible with the inclusion of Redis Role-Based Access Control (RBAC) users, user groups, and access strings in Amazon ElastiCache for Redis 6.x, there is no out-of-the box ability to associate ElastiCache RBAC users with IAM entities (roles, users, and groups).

Finding a Redis (Cluster Mode Disabled) Cluster's Endpoints (Console)

If a Redis (cluster mode disabled) cluster has only one node, the node's endpoint is used for both reads and writes. If the cluster has multiple nodes, there are three types of endpoints; the primary endpoint, the reader endpoint and the node endpoints .

Download and install redis-cli

Connect to your Amazon EC2 instance using the connection utility of your choice. For instructions on how to connect to an Amazon EC2 instance, see the Amazon EC2 Getting Started Guide.

Connecting to a cluster mode disabled unencrypted-cluster

Run the following command to connect to the cluster and replace cluster-endpoint and port number with the endpoint of your cluster and your port number. (The default port for Redis is 6379.)

Redis-cli alternative

If the cluster isn't cluster mode enabled and you need to make a connection to the cluster for a short test but without going through the redis-cli compilation, you can use telnet or openssl. In the following example commands, be sure to replace cluster-endpoint and port number with the endpoint of your cluster and your port number.

Overview

The following diagram, shows the high-level architecture of an example scenario of using AWS Client VPN and connecting to an RDS instance.

Generating a certificate

For instructions on creating a server certificate using OpenVPN easy-rsa tool, see Mutual authentication.

Creating a VPC and subnets

Create a VPC to host the subnets and the subnet group for the RDS instance with the following code:

Creating a security group

Create a security group to be used by the AWS Client VPN endpoint and the RDS instance with the following code:

Creating an AWS Client VPN endpoint

Create an AWS Client VPN endpoint and attach it to the VPC with the following code. You use the client IP4 CIDR to assign IP addresses to the client connections. Use your own server certificate arn generated in the previous step.

Creating an Active directory

Because the SQL Server RDS instance also uses Windows authentication, create an Active Directory to be associated to the RDS instance:

Creating the SQL Server RDS instance

To create an RDS instance, you need to create a subnet group and a directory service AWS Identity and Access Management (IAM) role. This IAM role uses the managed IAM policy AmazonRDSDirectoryServiceAccess and allows Amazon RDS to make calls to the active directory.
