Is it possible for a Data Connection agent to connect to NFS in order to transfer data?
There is no out of the box support for connecting directly, however, you could mount the NFS on the agent host (https://linuxize.com/post/how-to-mount-an-nfs-share-in-linux/), and then just use a standard Directory source to ingest the data.

When using Data Connection, can I ingest files into Foundry from an SFTP (SSH File Transfer Protocol, not FTPS) source?
Data Connection doesn't support STFP out of the box. However, there is a custom source.
Ask your Palantir team to install it.
Is it possible to run a local db with cloud backup where if the local db fails it changes over to cloud, so that new data stores in cloud until the failure is resovled, and then once resolved new data is copied to the local db and then the system resumes to use the local db. Any solution can be accepted ie aws or azure but how do i set it up where the db login address and configuration within the application stays the same.
I searched a lot and according my experience, there isn't any tools or Azure Service can do that.
I think it's impossible for now.
We have a local mysql server(not on public domain) and want that server replicated to a google cloud sql instance that we have. My question is that:
1. is this possible?
2. our local server is accessible on the local network only. no public IP, etc. Although the server has internet. Im not sure how replication works, is this a one way traffic from master to slave?
if this is the case, then this might be possible even if the local mysql server is not accessible on the public domain since it only need to connect to the slave up on the cloud.
hope this makes sense
MySQL replication requires a connection from the slave to the master. The easiest way to make this possible is to set up a DMZ or port forwarding so your SQL instance is accessible over the internet.
Google Cloud SQL does not support replication from off-site to Cloud SQL, but you can do it with MySQL on GCE.
If you do use MySQL on GCE you have the added option of using Cloud VPN to allow a connection from your GCE instance to your local MySQL instance without requiring public exposure of either.
Can Arduino Yun connect to MYSQL on External Server and store sensor data on it. If yes how?.
Technically you can.
You could write or port a mysql driver to the Arduino, but the small amount of memory and process power will make that no very easy.
With the Yún you could also install some libraries and program an app running on the linux side that forwards incoming data from the serial to your mysql database.
An other option:
Use an intermediary app to save incoming data to your database. The interface could be a typical HTTP API or via a publish/subscribe broker.
For simplicity I would recommend to go for option three.
i have a web application running on tomcat7 and mySql, now i want to deploy it to aws..
the application need to write file on disk (such as images uploaded by users)
some one can help me pointing out how to configure a good infrastructure in aws for my need?
i read this: http://aws.amazon.com/elasticbeanstalk/ , i think that my needs are an EC2 instance for running tomcat and an Amazon RDS whit mySql...
i need something else for R/W file ?
i need to change my code in some way in order to make it work on aws?
thanks in advance,
Loris
Elasticbeanstalk is a good way to get started with an application deployment at AWS. For persistent file storage you can use S3 or an EBS volume.
S3 allows you to read and write using amazon's SDK/API. I am using this on a java application running at AWS and it works pretty smoothly.
http://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/services/s3/AmazonS3Client.html
It is also possible to mount S3 over NFS, you can read some interesting points in this answer:
How stable is s3fs to mount an Amazon S3 bucket as a local directory
With EBS you can create a persistent storage volume attached to your EC2 node. Please note that EBS is a block level storage device so you'll need to format it before its usable as a filesystem. EBS allows you to help protect yourself from data loss by configuring EBS snapshot backups to S3.
