Waiting for Spring

Optimize and wait - Spring is coming. Winter is slowly turning its back on us here in Finland and the sun melts the frozen trees, snow slowly turns into water and we start having a little more sunlight. One has to wait until noon when the sun is at its highest point for optimal lighting. But once the sun is up, it's beautiful and full of hope.

Vaadin 7.4 released

Vaadin 7.4 released

Welcome to the next 7-series release. Vaadin 7.4 is the largest release we've had in a long time, featuring the new Grid component, declarative UI building and many more fixes. The Grid is the most advanced datagrid on the market, with features such as inline editing, filters, sorting, custom cell rendering and many others you've wished for in Table. There's so much new, it's almost a crime to call it a minor version.

Does it scale?

Does it scale?

As a rule of thumb, a typical Vaadin application scales up to 10 000 concurrent users per server. An application's scalability is affected by three things: the amount of server resources the application consumes per user, the number of concurrent users that are using the application at peak time and the number of servers. Take a look at how Vaadin tackles the common scalability issues at the newly launched Scalability-feature page.
