IndicThreads Cloud Computing 2010 Trip Report

Filed under: glassfish, javaee — arungupta @ 4:46 am had their inaugural conference on Upcoming Technology on Aug 20/21 in the city of Pune, India. As the name says, the goal of this conference is to talk about upcoming technologies and Cloud Computing was the chosen topic this time. Harshad & Sangeeta Oak – the driving forces behind Rightrix and this conference made it clear that this conference is not intended to be a training and the aim is to present the latest happening in the cloud world and get the attendees thinking. BTW, Harshad is also an Oracle ACE Director and a Java Champion. The theme of the conference was easily summarized in "Learn, Discuss, Debate, Argue".

Please provide feedback for the sessions at

I gave a session on "Running your Java EE 6 applications in the Cloud" and the slides are available below:

Running your Java EE 6 applications in the Cloud

I continue to stick to my philosophy of "Code is king" and showed several code samples & screen snapshots. Several attendees told me afterwards that they liked the session because it was well grounded.

The conference had a single track which gives you the ability to attend all the sessions, and there were several of them. Here are my brief notes from some of the sessions I attended. All the slides from different sessions are given below:

And now some notes …

Cloud computing – making the right choice by Kalpak Shah

  • Why cloud ?

    • No capital expenditure, only operational expenses
    • Reduced IT administration
    • Elasticity – Fast & inherent scale up/down
    • Commoditization of IT – Only storage, only content delivery, only messaging
    • Automation using APIs
    • Pay-as-you-go for tools & ecosystem
    • Reduced time to market, focus on core competency
  • Explained the concept of Iaas, PaaS, SaaS, and then Storage-as-a-Service (yet another SaaS)

    • Consideration for IaaS

      • Combine Support & Infrastructure – Amazon is cheap for infrastructure, costly for support
      • Cores are much slower on Amazon, faster on Rackspace
      • Good matrix for comparing IaaS vendors
    • Comparing PaaS & SaaS vendors

      • Development language & available skill sets
      • Ease of deployment & maintenance
      • Size of vendor & ecosystem maturity
      • Tools, monitoring, connectors, adaptors
      • Maturity of API & bindings available
      • Does vendor allow private cloud integration ?
  • Ways to Cloudify

    • Public clouds – Large datacenters, provide many services (CPU, storage, CDN, databases, etc), can try it, but comes with security, latency & bandwidth issues
    • Private clouds Normal on-premise databcenters with cloud with all usual benefits of elasticity, self-service, pay-asyou-go, programmabilty, offerings from VMWare, IBM, Microsoft, Eucalyptus
    • Hybrid clouds SaaS Virtual desktops for training Cloud storage for backup etc
  • Interesting private cloud platforms

    • Eucalyptus – Open-source IaaS cloud computing platform, compatbile with AWS enabling almost seamless movement with AWS, Extremely flexible and easy to administer
    • VMWare vCloud – Take the private cloud image, drag/drop on the public cloud and it just works. Platform is consistent & mature and it just works
    • Appistry – Application platform for private, public, and hybrid clouds
    • Rackspace – OpenStack compute and OpenStack storage
    • VMOps
  • Azure

    • Cloud services operating system
    • Provide services across the entire cloud stack – IaaS, PaaS, SaaS
    • Development, service hosting & management
    • Integrated with exisitng on -premises environment
    • Private cloud integration
    • Reliance is using Azure for some of their projects

Architecture Challenges in Cloud Computing by Prabodh Navare

  • Design for auto-scaling, high performance, failover, data portability, pay-as-you-go
  • Vertical scalability – write algorithms that are efficient
  • Horizontal scalability – Have the applications as simple/replicable as possible
  • Options for private cloud in open Source – Eucalyptus, Ubuntu enterprise Cloud, Open nebula, Nimbus, redhat

Getting started with jClouds by Vikas Hazrati

  • Fog, Deltacloud – Ruby-based multicloud library
  • Libcloud – Python-based
  • Dasein uses jclouds as their base API
  • jClouds easy to start

    • Simple interface (Map object)
    • OSS
    • Runtime portability
    • Java & Clojure
    • Unit testability across clouds
    • High performance because of NIO
  • Blobstore (atmos, azure, rackspace, s3)
  • Compute (vcloud, ec2, gogrid, ibmdev, rackspace, rimu)
  • Not 100% but pragmatic portability, dig in with extensions
  • Integration with Apache VFS to see the listing of Blobstore

Preparing data for your cloud by Narinder Kumar

  • Advantages of Non-relational DBMS

    • Scalability
    • Replication / Availability (less feature set but more performant)
    • Performance
    • Deployment flexibility
    • Modeling flexibility
  • Disadvantages

    • Lack of transactional support
    • Data integrity is app’s responsibility
    • Data duplication is app dependent
    • Eventual consistent
    • No standardization
    • New technology
  • RDBMS & Cloud

    • MySQL, Oracle, PostgreSQL, DB2, SQL Server are cloud-capable RBDMS
    • Microsoft SQL Services and AWS RDS are cloud native RDBMS
  • SQL Azure is built on SQL Server and so very intuitive.
  • Non-relational DBMS

    • Key value stores – Amazon Dynamo (not for public consumption), S3, Project Voldemort, Redis, Scalaris, MemCacheDB, Tokyo Tyrant
    • Document stores – CouchDB, mongoDB, riak, Amazon SimpleDB
    • Column stores – Google Column Store, Cassandra, HBase, Hypertable
    • Graph stores

Day 2 had interesting sessions on Azure by Janakiram M from Microsoft, EC2 by Simone Burnozzi from Amazon and multi-tenancy by Vikas from Inphina.

The Unconference at the end of Day 1 had some interesting topics like Cloud Standards, how Cloud can help fight massive scale diseases, and what a Java stack needs to provide in the cloud.

Over all, I had a great time, enjoyed some great conversations with Dhananjay Nene, Vikas Hazrati, Narinder Kumar, Rohit Naik, Navin Kabra, Manju, Amarpal Singh, and several others. I hope more attendees can join us for an impromptu social gathering in the evening. Anyway, looking forward to participate in the future Upcoming Technology conferences and others hosted by IndicThreads.
