Infrastructure as a Service

just few hours back I wrote this article & already we have a best usecase where in IaaS providers will gain , http://edition.cnn.com/2008/POLITICS/09/30/congress.website/index.html
this is exactly the LIVE unpresedented, un anticipated user bombardment which could happen to any application available online/internet, I feel if they had a IaaS solution they would have easily scaled up instaed of taking the site down , so in this case both the parties are in loss i.e. the visitiors who should have been able to view the legislative document which they could not & the gov in itself was not able to server its own stakeholders (citizens) who have the rights towards the service offered.

Honestly even though I have mastered the programming side of the IT world I get sleepless when it comes to deployments & managing the applications designed, be it the 24x7 up time, faster response, or scalability issues it always feel being challenged by the unknowns of this ONLINE WORLD of inter connected applications. Good news though now that services like Hadoop, Amazon EC2, SQS, SimpleDB or evn FPS it has shifted the power back to the developers in terms of getting to design & deploy scalable & expandable infrastructure on demand which I feel will make my job much easier when it comes to deploy on EC2/S3 as a file system while run the applications as an AMI (amazon instance), essentially that is helping a common developer by abstracting the low/system level challenges into fragmented API's those are easily understandable & usable within shorter span of time & that too without having to be the master of all the low level transactions. even though amazon has been building these systems since last few years I think we are on verge of seeing an exponential growth for companies & end users (programmers) who can build & be successful with very high end solutions, & in case they even remotely FAIL (obviously for the solution use case they tackle) they can retry/realign their product without having any impact on the infrastructure investments (which are base don how much you use ) & is bare minimum even in terms of $100 & NOT Millions what we have seen getting evaporated because of above issues.

Only things that concerns me are that while accessing these on "demand business objects" off the cloud we end up paying PER FETCH that could mean that the objects are expensive till they are ALIVE, so I am giving it a try to understand how much of cost advantage it is to manage a BUSINESS OBJECT off & on cloud based platform. Though initial cost seems to be minuscule though over time the archived data would becomes more expensive (I guess) which could be a major issue for large enterprises who have to archive huge chunks of data for Sarbens Oxley or any other corporate obligations....

Cloud Computing

having seen the traditional software development efforts over the last 12+yrs & having seen the way we always have common development issues in terms of supporting the product on the server side & the object data store which is of utmost importance to scale the application & also offering the backend support for the business data that is being transacted day in & day out.This demands a greater team of resources who have expertise handling the server side & transaction level details(OS, Server Hardware, Databases, Front/GUI API etc).
Flash forward to 2008 & we are already seeing great support to Cloud or "Platform as a Service" models giving breather to groups of innovators who have been delaying the efforts due to failed teams or expensive resources, personally I have been involved with metadata based applications & support the cloud model by heart, have always tried to project that companies do not need a team of IT developers to design/develope/maintain day to day business applications, Amazon EC2/S3 & other upcoming data storage as well as PaaS Services will make it easy & cost effective for all to build/deploy/ & maintain applications in cloud with minimal IT resources/teams.

SalesForce Integration

Sharing few thoughts that crossed my mind while integrating SalesForce web services API, overall I loved the ease & clear documentations as to SFObjects & their detailed usecases, building SOAP binding API with java was quick with Axis wsdl2java, also saleforce developer account setup helped to test the api calls without impacting the live site, though only hitch was that for developer account only 2 accounts (whic is understandable) are allowed to be ACTIVE though the API allows CRUD on non ACTIVE SFObjects,

SaaS Integration

Lately have been agressively doing SaaS application integration for my client. Have come across vendors allowing integration using xml & various flavour of soap integration, best of the breeds so far I have seen is the Salesforce integration API, we were up & running with all integration business needs within days & not weeks, still for some reasons there are vendors who offer web services in a custom pattern like WebEx which more or less is a xml over http/https , no object binding adds an extra step to marshal/de-remarshal objects using either a custom or standard/open source xml data/document convertor like Apache xmlbeans which does a greater automation converting objects defined in xsd to java bean patterns making it a breez when it comes to parsing xml http request & response from xml server.....

Metadata based application design

Have been instrumental in designing & developing metadata based enterprise applications. Now that SaaS & PaaS services are being offered by major vendors we are moving away from traditional product development models.Given the cost advantage along with the application infrastructure maintenance benefits I feel cloud computing is here to stay, so enterprise on demand is a reality.From CRM, Email, to hosted data services like Amazon s3 building a product offering seems like a click away, which I think will boost greater innovation & bring more competitive vendors in the market giving cost advantage to clients. So 3 cheers to metadata & multi tenant platforms, I feel the multi tenant should extend to multi technology so that 1 is not bound by the platform limitations, though the integration seems open ended via web services & xml the end user should have a choice to deploy the app using PaaS while choosing the technology he wants. that way he has the option to keep his product development both in sync on & off PaaS/SaaS frameworks.
