"Generally, Power BI paginated reports (SSRS reports) are optimized for printing, or PDF generation. Power BI reports are optimized for exploration and interactivity."
So, what really IS up with MSBI these days? Is SSRS getting shuttered? PBI has paginated RS-like reports, but not a lot of the other features SSRS provides. Microsoft marketing will continue to hate people like me who would go to great lengths to help keep alive an aging reporting technology. But the thing is- SSRS simply does the job for the vast majority of reporting use cases. In the last 18-20 years, there have been no major advancements in scheduling and snapshotting and otherwise caching and managing and distributing electronic information. And SSRS has all of that built in.
Nearly all of the advancements in reporting technology have come on the presentation and client-side. We can now create beautiful ad-hoc analysis and brilliantly composed interactive charts and other data presentations. But this all comes with a not insignificant price ($10 per user/month). And beyond the price, much like Azure SQL (vs. a genuine "Microsoft SQL Server" VM) and the extremely limited Azure SQL Workbench (vs. SSMS), there is a lot that Power BI cannot do well or at all.
You may have noticed the built-in SSRS reports in SSMS19's new QueryStore feature. These are very useful reports that can give DBAs an idea of how queries and being processed and what processes are consuming the most CPU. And it is a good example of a company "eating its own dog food".
I've seen SSRS installations that contained thousands of reports representing trillions of dollars of value, categorized and summarized with realtime security ownership, counterparty, price and other core trade data. Several of these business-ctitical reports had scheduled delivery and were cached and snapshotted programmatically.
Little old SSRS is a quiet but reliable business data spartan. To my surprise it is actually quite popular in the investment banking industries where stock valuations and company summaries on reports are a big part of the lifeblood that drives investment banking decision making.
And with a little bit of customization magic via things like ExtRSAuth, ExtRSNET48, ExtRS and other RS extension tools, SSRS and Power BI can be tailored-made to serve as a uniquely effective symbioses of print formatted, scheduled and data-driven management reports (SSRS) and ad-hoc or OLAP-based interactive data analysis charts with data visualizations (Power BI).
To answer the question of "when will SSRS be end of life?", I would say that SSRS isn't going away anytime soon. Microsoft has decided to combine SSRS and PBI (RS, .rdl reports are the "Paginated Reports" in PBI) in a way that serves both platforms. The PBI3.0 REST API indicates as much as the combined SSRS/PBI API offers a plethora of functionality that .NET developers can use to get the best of both worlds (SSRS and Power BI) and customize RS and/or PBI dashboards to support unique business processes.
The choice in what tool or tools you will enrich your printed reports and data visualizations with, is yours. Keep in mind that many organizations make use of both- with SSRS getting equal to more attention than PBI even to this day- not only because of the huge, global SSRS install base with all of these currently running SSRS reports- including many which support critical business and governmental processes across the globe. But also because Power BI requires a monthly subscription fee :( . Freeware seems to be slowly dying. Let's hope things change with the next version of SQL Server and maybe we'll get free* PBI.
SQL Server 2025? Happy reporting and data analyzing. Always remember that PBI and SSRS serve different organizational needs- ad-hoc analyzation of data and pixel-perfect, professional, print-ready reports, respectively.
*(at least a free "tier"? I mean c'mon MSFT..... developers want to CREATE, and MSBI data visualization creativity is dying behind that paywall)- SSRS and PBI should be free and work hand in glove. Anything less is a mistake and a gigantic missed opportunity, imho.
