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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"Portable object format (POF serialization) allows objects to be serialized and deserialized between Java and .NET so the two platforms can exchange data seamlessly."

"A robust standalone caching solution that prioritized speed of data serialization and data integrity was a must, and Coherence delivered on that front."

"It can handle an extremely high volume of data."

"We are storing information from one of our applications; this allows us to answer requests in milliseconds, while the application would take seconds to answer requests from clients."

"Introducing a data grid, we moved from a vertically scalable solution to full scalability."

"This product helped our organization to focus on implementing business logic without worrying about scalability on user loads of huge data queries."

"The product is stable and solid."

"Coherence has improved response times for queries of sizeable data sets, and by allowing for data distribution and replication through clustering, it improves the reliability of information systems."

More Oracle Coherence pros

"Varnish Enterprise has positively impacted my organization because the response time is an upgrade, as the response time for HTTP requests is more efficient and quick."

"Before and after implementation, there was a marked difference in the speed of the systems, and the users noticed it as well."

"The tool is really easy to install, very light, and extremely fast."

"Varnish Enterprise is not just a caching layer; it is a performance layer that enables showing real-time data with proper project architecture without issues."

"Varnish Enterprise has impacted my organization positively, as we are getting good clients because our websites are very fast and we are achieving good scores on Google Web Vitals."

"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."

"The reduction in latency with Varnish Enterprise has affected business outcomes positively because the conversion rate of search for the suggestions shown to users has been significantly higher than for the search pages they land on by manually typing out the whole query."

"Varnish Enterprise is quick and fast."

More Varnish Enterprise pros

Cons

"Oracle Coherence has considerable operational risks."

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

"Data transfer performance over geographical locations. Oracle database has better performance compared to Coherence when accessed from different regions."

"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."

"Initial setup is very complex; specifically, a lot of XML effort is required."

"The initial setup is complex and time-consuming."

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

"We have encountered the occasional minor bug and very occasional more serious bug."

More Oracle Coherence cons

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

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

"The monitoring features must be improved."

"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."

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

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

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