Caching has improved response times and reduces database load for high-traffic applications

Redis is very reliable, but it could be improved in areas such as monitoring, debugging, and feasibility into memory use. Better built-in tools for observability would help teams manage it more effectively at scale. Managing memory efficiently and troubleshooting issues can sometimes require additional tooling, so these areas can also be improved.One practical challenge I experienced is managing memory efficiently. Since Redis is in-memory, we need to carefully configure eviction policies and monitor usage. Debugging cache-related issues such as stale data or cache invalidation can sometimes be tricky. Additionally, tuning memory usage and eviction policies needs to be planned very carefully.

Caching has cut backend costs and traffic while configuration language still needs simplification

One of the best features Varnish Enterprise offers is how it maintains the cache, serving it via memory, which is very fast and helpful in our case. We did not want to add extra layers or scale our backend servers too much for cost reasons, and Varnish Enterprise was able to handle those requests well with its memory, as memory I/O is significantly faster than file system I/O. The configuration of Varnish Enterprise was easy because it uses Varnish Configuration Language, which takes some time to get used to, but it is manageable. I particularly appreciated the request routing feature; if a cached request is not found, Varnish Enterprise dynamically routes the request to backend servers. It also shields the backend traffic and IPs, adding an advantage. The challenge we solved with Varnish Enterprise is that it reduced RAM and resource consumption on the backend servers. When we added Varnish Enterprise, we did not see any spike in resource usage, but after removing it, we experienced a significant spike because all requests went to the backend servers, forcing us to scale up. Adding a single Varnish Enterprise server was enough since it maintained the cache efficiently, allowing for less scaling of the backend servers and containers, making it cost-effective. Varnish Enterprise positively impacted our organization by saving us a considerable amount of cost. Without Varnish Enterprise, we would need to scale our containers to around two hundred, but with Varnish Enterprise, we maintained fifty to eighty fewer containers while handling the same traffic, which was definitely advantageous.

However, I haven't explored Redis extensively for managing complex data structures beyond caching, as MongoDB might be more suitable for such scenarios."

"I use Redis mostly to cache repeated data that is required."

"The most valuable features of Redis are its ease of use and speed. It does not have access to the disc and it is fast."

"Redis is a simple service that does what it promises."

"Redis provides an easy setup and operation process, allowing users to quickly connect and use it without hassle."

"What I like best about Redis is its fast and easy use. It has interesting algorithms like HyperLogLog and provides useful features. It's also good for implementing scalable rate limiting."

Cons

"Making management easier, especially for teams operating large Redis clusters, would be helpful."

"The disadvantage of Redis is that it's a little bit hard to have too many clusters or too many nodes and create the clusters."

"I would prefer it if there was more information available about Redis. That would make it easier for new beginners. Currently, there is a lack of resources."

"If we use a lot of data, it will eventually cost us a lot."

"Redis presents a single point of failure and lacks fault tolerance."

"Redis could improve its efficiency in handling locally stored data, not just Amazon Cloud or Google Cloud."

"For the PubSub feature, we had to create our own tools to monitor the events."

"Sometimes, we use Redis as a cluster, and the clusters can sometimes suffer some issues and bring some downtime to your application."

More Redis cons

"Varnish Enterprise can be improved, particularly on the security features, as it does not differentiate itself compared to Cloudflare because it only provides the usual TLS termination and load balancing capabilities."

"The monitoring features must be improved."

"I think that the usage of Varnish Configuration Language can be improved."

"I have not seen a return on investment with Varnish Enterprise."

"The configuration can be somewhat rigid as it is quite technical. A newcomer might need to invest a lot of time learning how to set up a Varnish Enterprise layer on any project."
