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.
Cisco is a name well known in the IT field. The technology is tried and true and they have built a reputation on a solid platform. Though many people do not like the cost of the devices and the continued fees associated with long term ownership, you get what you pay for. I dont hesitate to recommend Cisco because I know people will get a solid product that will last a long time.

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

Easy setup and configuration. While the web UI has its quirks, setting up VLANs and other tasks which can be exceedingly complicated on other switches, are much easier on Cisco SG switches. You also have the ability to upload an existing configuration to switches, which can speed up the task of deploying many identical switches.
Features for the price. Getting a 48 port L3 switch with PoE+ for less than $2,000 is a great value.
Reliability. We have hundreds of the SG switches in dozens of client sites, many in harsh conditions, and they just keep going.

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.

The web UI has taken a turn for the worse with the latest firmware on the SGx50 models -- the bifurcation between basic and advanced modes and the changes to the way VLANs are modified is a step backward in my opinion.
The power bricks on smaller models are enormous. I'm sure, however, keeping this circuitry external to the switch is what keeps my switches running year after year in hot environments.
Fans can be a bit loud on larger switches -- this is true of pretty much any 1U device though.

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.

Cisco is more enterprise level, more reliable, and generally more feature rich but also very expensive. That being said old or refurbished Cisco switches are much more affordable and in comparison to even new switches from the competitor they are still a great value even though they are used. I like Ubiquiti switches as well but Cisco is usually better overall.

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.
