If the number of connections is expected to be low, but the amounts of data are large or projected to grow it is a good solutions especially if there is previous exposure to PostgreSQL. Speaking of Postgres, Redshift is based on several versions old releases of PostgreSQL so the developers would not be able to take advantage of some of the newer SQL language features. The queries need some fine-tuning still, indexing is not provided, but playing with sorting keys becomes necessary. Lastly, there is no notion of the Primary Key in Redshift so the business must be prepared to explain why duplication occurred (must be vigilant for)

I think this service works very well for me, but I have been a Verizon customer for almost 15 years. If you are someone who hops carriers it may not be the best fit. I also like that you can easily use it with all of your employees regardless if they prefer Android or Apple phones. (Whereas using Apple's or Google's services may not work seamlessly for all phones.) I think it still has room for improvement, and sometimes I worry about the longevity of utilization due to the nature of cell phone carriers constantly changing prices, plans, and every option under the sun to make a buck that we could be very screwed in the future if Verizon does something stupid (because historically, they all have)

[Amazon] Redshift has Distribution Keys. If you correctly define them on your tables, it improves Query performance. For instance, we can define Mapping/Meta-data tables with Distribution-All Key, so that it gets replicated across all the nodes, for fast joins and fast query results.
[Amazon] Redshift has Sort Keys. If you correctly define them on your tables along with above Distribution Keys, it further improves your Query performance. It also has Composite Sort Keys and Interleaved Sort Keys, to support various use cases
[Amazon] Redshift is forked out of PostgreSQL DB, and then AWS added "MPP" (Massively Parallel Processing) and "Column Oriented" concepts to it, to make it a powerful data store.
[Amazon] Redshift has "Analyze" operation that could be performed on tables, which will update the stats of the table in leader node. This is sort of a ledger about which data is stored in which node and which partition with in a node. Up to date stats improves Query performance.

We've experienced some problems with hanging queries on Redshift Spectrum/external tables. We've had to roll back to and old version of Redshift while we wait for AWS to provide a patch.
Redshift's dialect is most similar to that of PostgreSQL 8. It lacks many modern features and data types.
Constraints are not enforced. We must rely on other means to verify the integrity of transformed tables.

The home screen shows a little bit of everything, but being a control freak, I would like to be able to customize it. (Granted, it would most likely have most of the same elements, but, for example, I don't need photos scrolling across the top. I'd rather have buttons like quick links to jump directly to what I want or to see a further bird's eye view of the content.
I like receiving notifications that a back-up is complete, but I would like to be able to set what other notifications are and aren't allowed to push to my phone.
I have set Verizon Cloud to back up on wifi OR using the data network. But if you are using wifi while doing a content restore and you lose that connection, either by leaving the building or the local wifi dropping out momentarily, the entire content restore will stop and need to be restarted. This can be very frustrating.

Just very happy with the product, it fits our needs perfectly. Amazon pioneered the cloud and we have had a positive experience using RedShift. Really cool to be able to see your data housed and to be able to query and perform administrative tasks with ease.

The support was great and helped us in a timely fashion. We did use a lot of online forums as well, but the official documentation was an ongoing one, and it did take more time for us to look through it. We would have probably chosen a competitor product had it not been for the great support

Than Vertica: Redshift is cheaper and AWS integrated (which was a plus because the whole company was on AWS). Than BigQuery: Redshift has a standard SQL interface, though recently I heard good things about BigQuery and would try it out again. Than Hive: Hive is great if you are in the PB+ range, but latencies tend to be much slower than Redshift and it is not suited for ad-hoc applications.

All of the others provide more free storage. Verizon should out best or at least equal the best when you are already a Verizon data subscriber. It seems that by not doing this that they want to "nickle-and-dime" their already loyal customer base

Redshift is relatively cheaper tool but since the pricing is dynamic, there is always a risk of exceeding the cost. Since most of our team is using it as self serve and there is no continuous tracking by a dedicated team, it really needs time & effort on analyst's side to know how much it is going to cost.

Our company is moving to the AWS infrastructure, and in this context moving the warehouse environments to Redshift sounds logical regardless of the cost.
Development organizations have to operate in the Dev/Ops mode where they build and support their apps at the same time.
Hard to estimate the overall ROI of moving to Redshift from my position. However, running Redshift seems to be inexpensive compared to all the licensing and hardware costs we had on our RDBMS platform before Redshift.

Thus far is has been a positive experience, and has saved a lot of man hours of both employees who replaced their phones to the IT department trying to help them put everything back no longer needs to go through a lengthy process.
The cost of this option is a bit higher than I'd like. I think Verizon is a little too proud of a product that every company is now starting to offer.
There is a free version with limited space, so at least trying it out to see how it will fit with your needs isn't much of a risk.
