Today we're excited to announce Site-to-Site Virtual Private Network (VPN) support for Heroku Private Spaces. Heroku customers can now establish secure, site-to-site IPsec connections between Private Spaces on Heroku and their offices, datacenters and deployments on non-AWS clouds.

VPN is a powerful, proven and widely-adopted technology for securely combining multiple networks (or adding individual hosts to a network) over encrypted links that span the public Internet. VPN is well-understood and in use by most enterprise IT departments, and is supported on all major cloud providers and by a range of hardware and software-based systems.

Today we’re announcing a powerful new network control for apps running in Heroku Private Spaces: Internal Routing. Apps with Internal Routing work exactly the same as other Heroku apps, except the web process type is published to an endpoint that’s routable only within the Private Space and on VPC and VPN peered networks (see the Private Space VPN support companion post). Apps with Internal Routing are impossible to access directly from the public internet, improving security and simplifying management and compliance checks for web sites, APIs and services that must not be publicly accessible.

Need to quickly catch up on this past quarter's announcements? Here are the top three topics to tune in on:

Heroku has expanded regions availability for Private Spaces and introduced the general availability of the Dublin region on September 26, 2017. Heroku users are able to run apps in all of the following Private Spaces regions: Virginia, Oregon, Frankfurt, Tokyo, Sydney, and Dublin. Please verify that your add-on's manifest accurately reflect the supported Privates Spaces regions.

Heroku app webhooks for customers and add-on webhooks for partners are generally available. Partners are able to track many kinds of events relating to add-on resources on apps, domains, builds,...

Today we are happy to announce Heroku Shield, a new addition to our Heroku Enterprise line of products. Heroku Shield introduces new capabilities to Dynos, Postgres databases and Private Spaces that make Heroku suitable for high compliance environments such as healthcare apps regulated by the Health Insurance Portability and Accountability Act (HIPAA). With Heroku Shield, the power and productivity of Heroku is now easily available to a whole new class of strictly regulated apps.

Today, we are excited to announce DNS Service Discovery for Heroku Private Spaces, an easy way to find and coordinate services for microservice-style deployments.

As applications grow in sophistication and scale, developers often organize their applications into small, purpose-built “microservices”. These microservice systems act in unison to achieve what otherwise would be handled by a single, larger monolithic application, which serves the benefit of simplifying applications’ codebases and improving their overall reliability.

DNS Service Discovery is a valuable component of a true microservices architecture. It is a simple, yet effective way to facilitate microservice-style application...
