Hadoop has been an amazing development in the world of big data. Where relational databases fall short with regard to tuning and performance, Hadoop rises to the occasion and allows for massive customization leveraging the different tools and modules. We use Hadoop to input raw data and add layers of consolidation or analysis to make business decisions about disparate data points.

3. Storm

Apache Storm is a free and open source distributed real-time computation system. Storm makes it easy to reliably process unbounded streams of data, doing for real-time processing what Hadoop did for batch processing. The storm is simple, can be used with any programming language, and is a lot of fun to use!

The storm has many use cases: real-time analytics, online machine learning, continuous computation, distributed RPC, ETL, and more. The storm is fast: a benchmark clocked it at over a million tuples processed per second per node. It is scalable, fault-tolerant guarantees your data will be processed, and is easy to set up and operate.

Review: G2

What do you like best?
If you are needing real-time computing on most newer servers these days, apache storm has it covered, as one of the most reliable frameworks for batch processing.

What do you dislike?
I have used many apache products but getting this set up seemed to take much longer around 4hrs. After figuring everything out we were recommended a list of installation guides and support we wish we had prior.

Recommendations to others considering the product
If you have never used Apache before we recommend finding an authorized installer to set up as this would most likely speed up the process.

What business problems are you solving with the product? What benefits have you realized?
Realtime Server Accusation responses. Speeding up network response time from multiple branches within our network of over 200 systems.

4. Statwing

Statwing was built by and for analysts, so you can clean data, explore relationships, and create charts in minutes instead of hours. There is no faster or more delightful way to work with data, even if you’re already an expert with spreadsheets (like most of our customers).

Asking a simple question of your data in a spreadsheet takes minutes of shuffling data, creating charts and pivot tables, and writing formulas. Traditional statistical software was built decades ago for statisticians, so it requires technical expertise to ask even simple questions.

And unlike traditional software, statwing accounts for data issues like outliers, so you can always be confident in your analyses. Statwing also translates results in plain English, so analysts unfamiliar with statistical analysis can still get its benefits.

Review: Capterra

Comments: I used to use spss to do this kind of analysis. I didn’t think it was that bad at the time, but after using statwing I’m blown away by the difference. It’s just a lot easier to use, much more intuitive, and I get things done much more quickly.

The only knock is that it doesn’t have more sophisticated analyses like PCA or survival analysis. But I personally only needed the basic + regression analysis, so it worked well for me.

5. Cassandra


The Apache Cassandra database is the right choice when you need scalability and high availability without compromising performance.

Linear scalability and proven fault-tolerance on commodity hardware or cloud infrastructure make it the perfect platform for mission-critical data.

Cassandra’s support for replicating across multiple datacenters is best-in-class, providing lower latency for your users and the peace of mind of knowing that you can survive regional outages.

Review: G2

What do you dislike?
Weak Read performance and stability during automated tasks (table compression etc) – if heap gets over the limit, the node just crashes and don’t respawn.

Recommendations to others considering the product
Take into account, that each Cassandra node requires a decent amount of system requirements. About 4 GB of RAM is usually minimal, so running it in a cloud can be very costly. Second thing – do you have enough data? Cassandra is designed to store a lot of data, however, it lacks in other aspects. If you have very little data, other NoSQL options may be a lot better.

What business problems are you solving with the product? What benefits have you realized?
Storing vast amounts of meta information. It is intended to be quickly received and queried

6. Pentaho

The term big data applies to very large, complex, or dynamic datasets that need to be stored and managed over a long time. To derive benefits from big data, you need the ability to access, process, and analyze data as it is being created.

However, the size and structure of big data make it very inefficient to maintain and process it using traditional relational databases.

Review: TrustRadius

Pentaho is the primary source of business intelligence in my company. We have many Pentaho users across the whole organization that is making good use of Pentaho Analyzer to create the reports. At the reported side, it helps the business users to evaluate all the work that has been done by the different teams across the organizations.

By seeing the reports they can check, for example, how many issues are open, how many bugs have been fixed in a specific duration, how many builds failed in which phase, etc.

Review: techradar

The prospect of turning their regular, boring home into a smart one still seems a little bit scary and very time-consuming. Luckily, the hive active heating 2 is looking to change all of that and make upgrading your home easier, quicker and worth it in the long-run.

One of the main reasons why building up your smart home can seem scary is because there’s an assumption that you have to go ‘all in’ and upgrade everything to really see the benefits. This isn’t how it works. At least not anymore.

Review: TrustRadius

Qubole was used across the company to ease migration strategies from an on-premise Hadoop environment into the cloud. The end place for the data was between Amazon services such as S3 and RDS, but the initial goal was to use multiple clouds, as some parts of the company were using Google’s BigQuery.

From what I’ve seen, Qubole abstracts away the setup, scalability, and installation of many Hadoop services by providing an a la carte offering of big data processing services from query engines of Hive, Spark, and Presto to useful UI tools of the query editors and Zeppelin Notebooks.

Review: G2

CouchDB will be easy to pick if you are already familiar with JavaScript and JSON. The data is stored as JSON, and you use MapReduce functions in JavaScript to query the data. This makes it a nice complement to a full-stack JavaScript application running Node and a JavaScript front end.

If it fits the requirements of your application, you can use CouchDB as a REST API, and forgo the need for an additional API implementation on the server.

Easy to get started and good documentation to learn how to use the database. There is a GUI available to easily view your data.

What Do You Dislike?

The GUI that is available is not always intuitive. When I was first gettings started with it there were a few things that did not work as I expected them to that caused frustration.

The MapReduce query method can be hard to adjust to if you are used to traditional SQL databases. It is very powerful but takes some time to get familiar with it.

Recommendations To Others Considering The Product

As with most database decisions, you need to understand the needs of your application. CouchDB is well suited for document storage, but you will probably have an easier time with something else for a typical CRUD app.
