ELB Health Check return code

You can have TCP and HTTP health checks. A TCP health check will simply check if the web page exists (can be pinged essentially) a HTTP health check needs to return a 200 to pass the health check. More can be found here:

Bulk loading data to AWS from on premise

I spoke about bulk loading data to AWS in this blog post:

http://cloudconclave.blogspot.com/2013/04/on-premise-application-replication-and.html

A couple other options I did not mention are:

1. Apera - Asperasoft Company has developed a proprietary file transfer protocol based on UDP, which has shown to introduce very high-speed file transfer experience over the Internet.

2. http://docs.aws.amazon.com/ElasticMapReduce/latest/DeveloperGuide/UsingEMR_s3distcp.html   Apache DistCp is an open-source tool you can use to copy large amounts of data. DistCp uses MapReduce to copy in a distributed manner  You can also use S3DistCp to copy data between Amazon S3 buckets or from HDFS to Amazon S3.  Since it is based upon MapReduce, it is most applicable when moving HDFS and other map reduce files as you will obviously have MapReduce installed in your environment. 

Oracle specific protocol support on AWS ELB

Some Oracle customers are running Oracle specific protocols and when they move to AWS they would like to know if AWS services (such as ELB) support these products.  AWS ELB supports the HTTP, TCP, HTTPS and SSL protocols.  Oracle UCM IDC protocol is not supported with AWS ELB.  In looking at common on premise software and hardware load balancers (F5, Riverbed etc), I do not see any that support Intradoc (IDC).  The more important question to ask is: "What load balancer do you use on premise to load balance IDC traffic?"  If it is a software load balancer, you could run this on an EC2 instances.>

Another protocol that some Oracle customers run is Sockets Direct Protocol (SDP). SDP is an industry-standard wire protocol between InfiniBand network peers. When used over an InfiniBand network, SDP reduces TCP/IP overhead by eliminating intermediate replication of data and transferring most of the messaging burden away from the CPU and onto the network hardware.  This protocol is not supported on AWS.
