Infrastructuer Security at Premise Data
A stable and scalable relational database that ensures a return on investment for its users
The most valuable feature of the solution is its scalability. Scalability comes with two options, among which Google Cloud Spanner can scale horizontally, compared to other relational databases that scale vertically. You can change Google Cloud Spanner's resource configuration, which is done through processing units. Suppose you set up Google Cloud Spanner initially with a hundred processing units, and then you run out of resources since your database used too much CPU. In the aforementioned scenario, you can scale up or down and face no downtime in the production phase. The solution's features are important when running a company twenty-four hours, seven days a week.

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.

Quotes from Members

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

Pros

"It is a very scalable solution."
"The application deployment in the cloud is the best feature of the infrastructure."
"The most valuable feature of the solution is its scalability. Scalability comes with two options, among which Google Cloud Spanner can scale horizontally, compared to other relational databases that scale vertically."
"The solution is stable and reliable."
"Google Cloud Spanner is stable."
"We can scale the solution if we need to."
"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."
"Redis is a simple, powerful, and fast solution."
"Redis provides an easy setup and operation process, allowing users to quickly connect and use it without hassle."
"It is particularly efficient for cloud-based storage and operations."
"The ability to fetch and save data quickly is valuable."
"The performance of Redis is very fast."
"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."
"The product offers fast access to my database."
 

Cons

"I want to improve the deployment of cameras and surveillance infrastructure."
"The tool lacks to offer AI features."
"Google came up with something called Cloud Spanner Emulator, which fails to work like the real product if I want to develop some code and run a database locally on my machine."
"The cost can be a bit high."
"The tool needs to improve horizontal scaling."
"The development of clusters could improve. Additionally, it would be helpful if it was integrated with Amazon AWS or Google Cloud."
"There are some features from MongoDB that I would like to see included in Redis to enhance its overall efficiency, such as the ability to perform remote behaviour. MongoDB is more efficient in handling updates than deletions and is quicker in processing updates, but it can be slower regarding deletions. This can sometimes pose a challenge, especially when dealing with large datasets or frequent data manipulations that involve deletions. In such cases, I often rewrite columns or update values instead of directly deleting data, as it can be more efficient."
"The only thing is the lack of a GUI application. There was a time when we needed to resolve an issue in production. If we had a GUI, it would have been easier."
"Managing memory efficiently and troubleshooting issues can sometimes require additional tooling, so these areas can also be improved."
"Redis could be improved by introducing a GUI to display key-value pair database information, as it is currently a CLI tool with no visual representation."
"The initial setup of Redis was difficult, with a rating of two or three out of ten."
"Redis should have an option to operate without Docker on a local PC."
"Redis could improve its efficiency in handling locally stored data, not just Amazon Cloud or Google Cloud."
 

Pricing and Cost Advice

"It is expensive."
"The solution is expensive."
"Price-wise, I heard that Google Cloud Spanner is on the higher side."
"Google Cloud Spanner is an expensive solution."
"Redis is an open-source product."
"Redis is an open-source solution. There are not any hidden fees."
"We saw an ROI. It made the processing of our transactions faster."
"Redis is not an overpriced solution."
"The tool is open-source. There are no additional costs."
