We currently use Tableau Online. I am wondering if there are differences from Tableau Server as in cost per year, report sharing and performance.
Here's a link to up-to-date Tableau pricing:
https://www.tableau.com/pricing/teams-orgs
"On Premise and Public cloud" refers to Tableau Server and "Fully hosted by Tableau" refers to Tableau Online
Tableau Server licensing cost is less than Tableau Online but with Tableau Online you don't have to purchase or maintain the infrastructure (server) which hosts the software. In my opinion Tableau Online is generally more cost effective for smaller scale solutions and any upgrades are managed by Tableau whereas Tableau Server is generally better if you want to keep all your data on premise or for larger solutions.
I don't think there is any difference in terms of sharing reports.
Performance wise, Tableau Online runs on a shared infrastructure whereas you can choose the spec of the server you run Tableau Server on. If performance is a concern, then you have more flexibility with Tableau Server and you can usually situate the server closer to the data source and spec the server as high as you need.

We're evaluating ITextSharp (now known as IText) for producing pdf documents. This will be used in our websites which will be published across a load-balanced solution amongst several servers.
According to Itext, this will require a production license per server (we're not open-source) in our load balanced configuration, as well as uat and developer licenses. This is obviously a considerable investment.
Could anyone recommend any alternatives to reduce the costs?
Also, is there a pattern we could adopt to minimise the migration effort of the existing website prototype if we were to use another product?
You could change your architecture a bit and have a dedicated PDF generation server. You'd then need to boil your requests down to something that could be sent between the servers. Depending on your goals, that could be something relatively simple, such as a user ID and a report name, or complex (text layout, that image there).
As far as distancing yourself from the commercial iText, there are two options.
1) Use the older MPL iTextSharp. It won't have all the latest features and bugfixes, but it's hard to beat the price.
2) The "wrapper" design pattern. Build a relatively generic interface, and have your current implementation of that interface sit atop iText. If you later need to swap it out, you're rebuilding the glue code, not your whole app.

Recently I learned Tableau Visualization tool but I am not able differentiate between Tableau and QlikView.
could any one detailed me what's functional difference, I take round in google so please don't reply copy past from google.
Not a detailed functional difference analysis, no, but an overview as I see it.
Tableau is, as you say, a visualisation tool - it has some fairly simple data loading capabilities, but for complex environments relies on other data extraction tools like Alteryx. Tableau focuses on the front-end with things like a wide range of chart types, recommended chart types based on the nature of the data. That said, it is not a fully-responsive web-based product - you design separately for mobile and other different screen resolutions.
QlikView it's fair to say isn't as "pretty" as Tableau, but it does have a very powerful data extraction script language as well as in-memory associative technology for very fast data analysis. It's also not fully-responsive in a web browser - although it does have some limited mobile functionality that works out of the box.
You should also look at Qlik Sense (essentially the successor to QlikView) which seems to me to be the best of both worlds - it's visually appealing like Tableau but has the powerful ETL tools and in-memory technology of QlikView.
Hope that helps. I think the Gartner BI 2017 report just came out, so it'd be worth looking at that for a broader overview of capabilities across BI tools.

Our Raw Data is in SQL SERVER,Data keep on growing,Growth rate is high,We need to load the data incrementally to Redshift for Analytics.Can you please point out me a good practice to load the data.How feasible with SSIS to load directly to Redshift (with out S3).
It's going to be impractical to load from SQL Server to Redshift without landing the data on S3. You can try loading via SSH but, of course, SSH on Windows is not well supported.
http://docs.aws.amazon.com/redshift/latest/dg/loading-data-from-remote-hosts.html
I did a presentation a while back on what we discovered when migrating from SQL Server to Redshift. One of the things we discovered was that SSIS was not very useful for interacting with AWS services.
http://blog.joeharris76.com/2013/09/migrating-from-sql-server-to-redshift.html
Finally, you could look into some of the commercial "replication" tools that automate the process of incrementally updating Redshift from an on-premise database. I hear good things about Attunity.

i want to know detailed information about JD Edwards. How is used JD Edwards? Generally, what can I do in jd edwards? i've searched about it but cannot find wished info.
JD Edwards is an ERP for managing a business
There's a wiki that explain it very well http://en.wikipedia.org/wiki/JD_Edwards
The complete documentation of the product can be found on the oracle web site http://docs.oracle.com/cd/E16582_01/index.htm
JDE has many modules (but not limited to)
Manage projects
Human resources
Procurement
Sales Order
Supply management
CRM
Finance
Pricing
Transportation
Work order
and many more
Jdedwards is oracle ERP. Platform where it can be installed is real time platforms of customers. Osperating System it uses is windows or IBM As400. Just think that SAP is bigger business clients ( Adidas puma) and JDE is smaller and for medium business clients ( banks shops stores) choice. Customer asks service and support for smooth transactions. Customer interface with the database is interfaced by a frontend software just call this Jde. Next jde is two types on the basis of backend database wich is used by customer, IBM Db2 and Oracle 12g. So customer saves store data in database through Jde. The above Wikipedia link can answer most answers.

I keep finding -quite interesting- job positions that require knowledge of this specific framework. My question is: It's worth gaining laboral experience at TIBCO? Besides the job search related sites, where can I find trustful information regarding the current use of a framework/technology?
And, on which factors does usually depend the success of certain programming framework amongst others?
I want to figure out if TIBCO will have a long-term future. Thank you for any help you can provide on this subject.
(Feel free to edit if the question(s) can be formulated better ^^)
TIBCO BusinessWorks (I assume you are talking about that specific product, out of the very large TIBCO product selection) is an integration software. As such, you should learn it if you are interested in working in the integration field.
FYI : Integration requires a lot of soft skills and complex problem resolution techniques. It is mostly related to data routing and transport (think: REST-enabling Mainframe software).
As for selecting TIBCO products, I personally believe the company to be a great integration software provider.
TIBCO is a lot more than BW ! Many products deserve attention, such as EMS, Service Grid, BPM, MFT, Spotfire, etc.
How popular really is TIBCO ?
It might be simplistic, but I like to use Google Trends for that sort of questions...
TIBCO vs Websphere vs webMethods vs Spring int : TIBCO 2nd, Websphere 1st (dropping rapidly)
TIBCO alone (a steady slow drop, but still strong)
TIBCO EMS vs MQ vs Active MQ vs RabbitMQ : EMS steady (but not high), RabbitMQ rising
Some topics like TIBCO Spotfire have some more traction...
