Facilitating real-time business insights with enhanced data querying

Coherence is beneficial due to its multi-indexing to the same object and filtering based on data attributes within the object, followed by aggregation. These features facilitate querying data with multiple keys rather than just a single key. Its real-time data processing capabilities provide insights for business decisions with up-to-date information.

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.

More Varnish Enterprise pros

Cons

"Configuration is too complex."

"Cluster management tools that are independent of WebLogic. Dynamic cluster config rollout and rollback."

"Technical support is 3 or even 2 out of 10. Working directly through an account rep or a contact on Coherence dev team helps a lot."

"The price is high. I believe there should be a cheaper version for only the caching solution."

"It is very easy to set up a basic topology, but hard to configure and tune to make it really work."

"It has become very heavy along with the price for Oracle's integrated product as a fusion middleware."

"Due to the licensing prices, we are looking for other solutions as an alternative to Coherence."

"Complexity being a huge contributor to risk/cost for projects, I am more likely to use other products as a result."

More Oracle Coherence 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 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."

"I think Varnish Enterprise can be improved from a user experience point of view."

"The monitoring features must be improved."

"We were forced to move out of Varnish Enterprise."

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

"I think Varnish Enterprise can be improved as the prices can be cheaper."

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