Solr spins up nicely and works effectively for small enterprise environments providing helpful mechanisms for fuzzy searches and facetted searching. For larger enterprises with complex business solutions you'll find the need to hire an expert Solr engineer to optimize the powerful platform to your needs. Internationalization is tricky with Solr and many hosting solutions may limit you to a latin character set.
Due to its perpetual licensing model, VMware Fusion is a great option for users whose needs do not change as much over time. It is also great for occasional-use scenarios such as testing and preparing code to run on newer platforms. Fusion is not really recommended for running graphics-intense applications as graphics acceleration in Fusion is fairly limited in both performance and API support. It has, however, come a very long way and offers near-native performance for many tasks.
Easy to get started with Apache Solr. Whether it is tackling a setup issue or trying to learn some of the more advanced features, there are plenty of resources to help you out and get you going.
Performance. Apache Solr allows for a lot of custom tuning (if needed) and provides great out of the box performance for searching on large data sets.
Maintenance. After setting up Solr in a production environment there are plenty of tools provided to help you maintain and update your application. Apache Solr comes with great fault tolerance built in and has proven to be very reliable.
These examples are due to the way we use Apache Solr. I think we have had the same problems with other NoSQL databases (but perhaps not the same solution). High data volumes of data and a lot of users were the causes.
We have lot of classifications and lot of data for each classification. This gave us several problems:
First: We couldn't keep all our data in Solr. Then we have all data in our MySQL DB and searching data in Solr. So we need to be sure to update and match the 2 databases in the same time.
Second: We needed several load balanced Solr databases.
Third: We needed to update all the databases and keep old data status.
If I don't speak about problems due to our lack of experience, the main Solr problem came from frequency of updates vs validation of several database. We encountered several locks due to this (our ops team didn't want to use real clustering, so all DB weren't updated). Problem messages were not always clear and we several days to understand the problems.
For Apple workstations VMware Fusion is the virtualization software to use. No other application (free or paid) can do what Fusion can. The features and constant updates make Fusion an application that cant be beat.
I made an 8 because it's good in almost every aspect. As I said if you are on macos and you need both windows and linux I think is the best options out there. Otherwise if you need only windows there is a competitor that could be better for performance and integration.
I have never contacted VMware, but there is a lot of support online on message boards, forums, StackOverflow, YouTube tutorial videos, and the like. VMware has been around nine years longer than its leading competitor, VirtualBox, although both seem to have a good presence of online user communities who can help solve issues that come up.
I've heard of other/competitive software but frankly once I tried VMware, I never looked back. There is absolutely nothing that I need that this product does not deliver. It's fast, effective and seems to be extremely durable and reliable. My only concern (and minor) might have to do with memory resources, but frankly it has not been an issue yet.
Users using a VM often don't need something as "fancy" as VMware Fusion, and instead can use a free option like Virtual Box, so we waste money on using an extra amount of VMware Fusion licenses.
Developers using and IT admins using VMware Fusion for testing saves us time and money. Simply, we know mistakes would take time and money to fix, but VMware is powerful, allows for proper and fast testing.
