I'm tasked with creating a hyperledger application that will represent a consortium of same-skilled organizations.
I have the barebones prototype with a network of 2 orgs, built by following the fabric-samples example that I created as a capstone project; I am looking to upgrade the application to a production level.
My question is, is there a GUI/platform available to create and maintain hyperledger fabric networks?
What are the alternatives for tools like the Console?
What would be the best way to start building such an application considering the goal is to get to the production level?
Is IBM Cloud Blockchain Platform the best option for me?
Thank you for taking the time to reply.
I know of Hyperledger Console. I have used it previously for school projects. But can it be used to create and maintain+govern a production-grade HLF app?
IBM Blockchain Platform on IBM Cloud is withdrawn (https://www.ibm.com/common/ssi/cgi-bin/ssialias?htmlfid=872/ENUSWP22-0062&infotype=AN&subtype=CA). But the console is open sourced as https://github.com/hyperledger-labs/fabric-operations-console
I have some SAPUI5 Fiori applications developed using SAP WEB IDE in the Neo platform. Now I need to migrate those applications to the cloud foundry environment. So far as I checked there are few differences in the application files of NEO & Cloud Foundry.
eg:
Neo has neo-app.json and cloud foundry has xs-app.json
Are there any guidance or information related on correctly migrating SAPUI5 apps from Neo to Cloud Platform.
There are indeed not that many differences but there is some different handling in terms of tooling files, etc ...
I would propose to create a new multi-target test project using the provided standard templates and then add a UI5 test template subproject.
That will give you an idea of how the CF UI5 project structure looks like and which files are being generated.
It also depends on whether you are going to use the new HTML5-repo application architecture or not. That newer format has more impact and changes under the hood.
I followed the instructions on IoT Asset Tracking on a Hyperledger Blockchain . BUILD and DEPLOY finished successfully, but I can't find the composer-rest-server- app under Cloud Foundry Applications.
I can use the CF Blockchain services, enter the Monitor and open the Swagger UI. The question is, where can I find the application-specific APIs mentioned in the tutorial:
If everything deployed correctly, you can find the app in the IBM Cloud dashboard at https://console.bluemix.net. If you have many apps and services deployed, make sure to filter correctly or to be aware of paging.
If you suspect that something got wrong during build and deploy, go to the toolchain and check the logs. The toolchains can also be reached from the dashboard.
I would like to know the different approaches to deploy the locally built MobileFirst hybrid application to dedicated Bluemix environment.
I have used containers from public Bluemix environment to create worklight console to deploy wlapp and adapter files. Containers are not available in dedicated Bluemix environment.
Is there anything we can do to deploy the files in dedicated environment?
Thanks in advance.
The ability to use containers in a dedicated Bluemix environment is not supported at this time.
That is correct that the IBM Container Service is not yet available as part of the Bluemix Dedicated offering but we are working on making the Container Service available in the dedicated offering so stay tuned.

I love Heroku but I would prefer to develop in Scala rather than Ruby on Rails.
Does anyone know of any services like Heroku that work with Scala?
UPDATE: Heroku now officially supports Scala - see answers below for links
As of October 3rd 2011, Heroku officially supports Scala, Akka and sbt.
http://blog.heroku.com/archives/2011/10/3/scala/
Update
Heroku has just announced support for Java.
Update 2
Heroku has just announced support for Scala

Check out Amazon Elastic Beanstalk.
To deploy Java applications using
Elastic Beanstalk, you simply:
Create your application as you
normally would using any editor or IDE
(e.g. Eclipse).
Package your
deployable code into a standard Java
Web Application Archive (WAR file).
Upload your WAR file to Elastic
Beanstalk using the AWS Management
Console, the AWS Toolkit for Eclipse,
the web service APIs, or the Command
Line Tools.
Deploy your application.
Behind the scenes, Elastic Beanstalk
handles the provisioning of a load
balancer and the deployment of your
WAR file to one or more EC2 instances
running the Apache Tomcat application
server.
Within a few minutes you will
be able to access your application at
a customized URL (e.g.
http://myapp.elasticbeanstalk.com/).
Once an application is running,
Elastic Beanstalk provides several
management features such as:
Easily deploy new application versions
to running environments (or rollback
to a previous version).
Access
built-in CloudWatch monitoring metrics
such as average CPU utilization,
request count, and average latency.
Receive e-mail notifications through
Amazon Simple Notification Service
when application health changes or
application servers are added or
removed.
Access Tomcat server log
files without needing to login to the
application servers.
Quickly restart
the application servers on all EC2
instances with a single command.
Another strong contender is Cloud Foundry. One of the nice features of Cloud Foundry is the ability to have a local version of "the cloud" running on your laptop so you can deploy and test offline.
I started working on the exact same thing as what you said a few weeks ago. I use Lift, which is a great framework and has a lot of potential, on top of Linux chroot environment.
I'm done with a demo version, but Linux chroot is not that stable (nor secure), so I'm now switching to FreeBSD jail on Amazon EC2, and hopefully it'll be done soon.

There are also other Java hosting environment including VMForce mentioned above.
If you are looking for a custom setup which also has the ease of deployment that heroku offers: http://dotcloud.com. They are invite only right now but I was given access in under three days. I am working on a Lift/MongoDB project there and it works well.
Off the top of my head, only VMForce comes to mind, but its not available yet. This will be a Java-oriented service, so that probably means you'll have to spend a wee bit of time figuring out how to package the app.
For more discussion, there was a debate about this in 2008.
I'm not entirely sure if it's really suitable or not, but people have deployed Scala applications to Google App Engine, for example http://mawson.wordpress.com/2009/04/10/first-steps-with-scala-on-google-app-engine/
Actually you can run scala on heroku right now. You don't believe it?
https://github.com/lstoll/heroku-playframework-scala
I'm not sure the tricks lstoll has used are legit but using the
new cedar platform where you can run custom processes and some
ingenious Gemfile hacking he has managed to bootstrap the Java
play platform into a process. Seems to work as he has a live
site running a test page.
Stax cloud service offers preconfigured lift project skeleton. Also, there is a tutorial on how to deploy lift project to appengine.
