Presto is an open source SQL query engine designed to run queries on data stored in Hadoop or in traditional databases.
Teradata supported development of Presto followed the acquisition of Hadapt and Revelytix.
Oracle Exalogic in conjunction with an Oracle Exadata based platform is what I would consider the best of breed solution; however the performance may be overkill for what you need. Don't spend the money unless you need the performance, Oracle offers other solutions at a much lower cost. Purchase what you need not what's the shiny new product.

Presto is for interactive simple queries, where Hive is for reliable processing. If you have a fact-dim join, presto is great..however for fact-fact joins presto is not the solution.. Presto is a great replacement for proprietary technology like Vertica

Private Cloud: in the virtual configuration, you can create several accounts and assign different resources (vCPU, RAM, etc.) to several departments in your organization.
SDP & Infiband: Oracle Exalogic can be connected to Oracle Exadata using Infiniband Fabric, to take advantage of high bandwidth and low latency network to connect Weblogic to Oracle Database.
Standardization: Oracle Weblogic Server running on Oracle Exalogic is the same software running on a normal Linux machine, so you can easily move Java applications without changing it, and immediately benefit from the Exalogic Optimizations.

Linking, embedding links and adding images is easy enough.
Once you have become familiar with the interface, Presto becomes very quick & easy to use (but, you have to practice & repeat to know what you are doing - it is not as intuitive as one would hope).
Organizing & design is fairly simple with click & drag parameters.

Currently, the management of Exalogic is a little arcane. There is a good chance that Oracle can bring flexibility into the control stack because we have seen changes with each version of the software Echo was an improvement and foxtrot even more so. The ability to easily change VM shapes was another welcome change.
Again the fact arises that to build a very high performance machine there will be idiosyncrasies and a certain amount of retraining may be required. I think this is one area where Exalogic lacks not as a product but as a solution is that there isn't as much good knowledge available about it as there is for other engineered systems.
The Exalogic default setup could do with an SSD storage option, currently the onboard comes with a spinning disk.

Presto was not designed for large fact fact joins. This is by design as presto does not leverage disk and used memory for processing which in turn makes it fast.. However, this is a tradeoff..in an ideal world, people would like to use one system for all their use cases, and presto should get exhaustive by solving this problem.
Resource allocation is not similar to YARN and presto has a priority queue based query resource allocation..so a query that takes long takes longer...this might be alleviated by giving some more control back to the user to define priority/override.
UDF Support is not available in presto. You will have to write your own functions..while this is good for performance, it comes at a huge overhead of building exclusively for presto and not being interoperable with other systems like Hive, SparkSQL etc.

It is a very condensed version of what used to be rows of servers. I like that storage, networking and compute nodes fit in one rack. The power and the software are top notch. The only problem is cost. You need to do some serious processing to get the true value out of the Exalogic system.

It's hard to compare Oracle Exalogic Engineered Systems with anything else on the market. It's so purpose built for application performance and intended to be used in conjunction with other Oracle Engineered Systems. As I alluded to earlier in this review the cost may not be worth the investment if the performance isn't needed. Oracle offers other solutions like the Oracle PCA which will meet the need for licensing compliance at a much lower cost of ownership and may fit better into your current infrastructure.

Presto is good for a templated design appeal. You cannot be too creative via this interface - but, the layout and options make the finalized visual product appealing to customers. The other design products I use are for different purposes and not really comparable to Presto.
