Like any other SSL protocol, stunnel requires a certificate to use for client to server communication. non-TLS aware daemons running on your system can communicate with clients over secure TLS channels. It works as TLS encryption wrapper between remote clients and local or remote servers. Stunnel is a Transport Layer Security (TLS) offloading and load-balancing proxy. “stunnel” is of the TLS wrappers which is available for free. A TLS proxy can be used with redis-cli to enable it for connection to Redis over an encrypted link. However, redis-cli doesn’t support SSL or Transport Layer Security (TLS). To access data from ElastiCache for Redis nodes enabled with in-transit encryption, you must use a client that works with Secure Socket Layer (SSL). In addition, you can also perform the following actions on the database:Ĭonnecting to Redis with in-Transit Encryption Enabled Which commands are being process by the server right now?.What key-values pairs are currently stored in the database?.Who is connected and from what IP address?.If you feel the need to interact with the database and get the following questions answered, you need to connect to the database using a client tool: From CloudWatch, you can look at the following counters individually or create a custom dashboard to include them all in it. You can navigate to the ElasticCache dashboard and view service level events (Services > ElasticCache > Events). It offers different levels of on-disk persistence and clustering for high availabilityĪWS Web console gives you very limited options to monitor Redis health and activity. Redis is a popular choice for caching, session management, real-time analytics, geospatial, chat/messaging, media streaming, and gaming leaderboards. It delivers sub-millisecond response times enabling millions of requests per second for a variety of real-time applications. Redis is an open source, in-memory, key-value data store for use as a database, cache, message broker, and queue.
