Summary:

PaaS player Heroku launches bigger, faster — but still lightweight — Performance XL Dynos for web-scale applications.

On Monday, Heroku launched what it’s describing as bigger Dynos that are better suited than the current generation to support web-scale applications. In Heroku terminology, a Dyno is actually a lightweight virtualized container to run your commands. Basically, it represents the resources needed to run an application.

The new XL Performance Dynos are 40 times the compute power of traditional Dynos and are “tuned for the new apps” flooding the market, Heroku VP Adam Gross said in an interview. A Heroku blog post outlines XL Dynos’ features, but the chart below sums up the sales pitch:

performance dynoThis move comes as Amazon Web Services keeps rolling out new, and more powerful instance types and as developers look to what some see as container-ish PaaS alternatives like Docker. The development platform competitive landscape is nothing if not fluid.

Also new is a run-time metrics capability that lets developers see how their Dynos are running. And Heroku has launched round-the-clock support with a one-hour Service Level Agreement (SLA) on critical items for $1,000 per month or 20 percent of the total bill, whichever is greater. Gold rejoined the Salesforce.com/Heroku universe last fall when Salesforce.com bought his startup cloudconnect.

Salesforce.com bought Heroku four years ago and has pretty much run it as an independent entity since then. The fact that Salesforce.com fields its own Force.com PaaS as well led to some confusion. At Dreamforce last fall, Heroku tried to make sense of the two PaaSes, oddly enough, by launching a third — Heroku1, a Salesforce.com-focused version of Heroku — and positioning it as the best PaaS for designing customer-facing applications in the Salesforce.com universe. Force.com, meanwhile, is for employee-facing applications.
