We use HAProxy because it offers us the option to balance requests between multiple ElastiCache nodes without explicitly using additional cloud services. We’ll establish an SSH tunnel to an instance running HAProxy without having to manage any SSH bastion hosts or open inbound ports for external access.

We’ll also show you how to use port forwarding through AWS Systems Manager Session Manager (SSM) in your development process. The same mechanisms apply for any resources inside a private subnet (for example, an Amazon Aurora DB cluster).

This use case is not limited to ElastiCache for Redis. In this blog post, we will solve a connectivity obstacle where developers have to query a remote Redis cluster because replicating the same development data locally is not feasible. However, placing resources in private subnets and restricting system access inevitably limits how developers can interact with the system and develop or test new features. An ElastiCache cluster can quickly become a valuable target, so it’s important to keep every data storage medium as secure as possible.įor this reason, one of the core security and infrastructure design best practices is to encapsulate resources in private subnets of Amazon Virtual Private Cloud (Amazon VPC) and limit the inbound access of resources using mechanisms like security groups. Malicious parties are always on the lookout for ways to exploit security flaws and obtain access to customer data. Amazon ElastiCache for Redis is versatile in-memory storage that offers highly available, highly scalable, and extremely fast retrieval time for frequently queried data.

When it comes to optimizing the response time of read-intensive applications, data caching is one of the first steps to consider. With the increasing adoption of the public cloud, customers must minimize the attack surface of their infrastructure.
